Definitions
- This invention relates to an advertising or signaling apparatus of the same class as described in the specification of my pendmg application, Serial No. 642,030 filed 2nd August, 1911, but in the present invention improvements have beenintroduced in the construction of the elements; in the method of electrically-connecting same; in the means for controlling the elements section by section; and in the arrangements of connections leading thereto for automatically actuating the elements.
- the objects of these improvements have been to render the apparatus more versatile so that it is capable of reproducing devices, words, phrases, letters or signs in a larger variety and in a larger number of methods or order of appearance and capable of being controlled by fewer conductors, than is posgized.
- each individual element is so constructed that it possesses a double predetermining function and a double operating function, the predetermining function being operable without disturbing or actuating the visual section of the element, this predetermining function being provided by what may be called a primary relay and being controlled,
- the invention also comprises means of constructing the electro-magnetic devices of both the-relay system and the actuating system in such a manner that the displaying and non-displaying functions of each element may each be connected in series and a group of such elements may also be connected either in electrical series, parallel or combinations of series and parallel.
- Figure l the back of the lamp e thus disclosing the is a sectional side elevation of one form of members for display when light falls upon.
- the .non-luminous member and it may be provided with a lamp, preferably electric, capable'of illuminating or defining the, position of the said visual member during, night orfor the period that sufiicient light does not fall upon its surface to properly visualize it, such lamp being hereinafter termed "the luminous member, the term visual member being applied'to the members adapted for display both in light and darkness and the term sign being used to denote an assemblage of elements together with their cellular or other supporting back ground and" controlling means.
- the element andits means for direct actuation is constructed as a self-contained unit removable as a whole from its supporting back ground, such method of construction being adopted to facilitate manufacture, repair and transport as described in the previous specification aforesaid.
- Fig. 1 represents an'element with a hemispherical shutter a adapted to be rotated as by means of the pinion b and rack 6 upon the center d into a position at member f which may consist of white opal glass also of hemispherical form containing a lamp e and termed the visual member.
- the rack b is pivoted at 0 and has an extension consisting of a magnetic device or armature 71..
- the power coil 71 Located in proximity to said armature are the power coils i and j and if it is desired to display the visual member f, the power coil 71 is energized, thus attracting armature k and rotating the rack upon the pivot c, causing the shutter a to rotate upward and backward and assume a position behind said visual member, (the travel being limited as by a stop is), causing it to be the said shutter will not be easily brought to rest in any position between fully open and fully closed (in front of or behind the visual member) since gravity always tends tobrin it into one or the other extreme position, an
- the force of gravity will cause the shutterv to continue its travel until it is arrested "by the stop 70, this action occurring both in displaying and causing non-display of the visual member, the force of gravity being used to practically lock or retain the shutter in a position in front of or behind the visual member f.
- the plunger vm of the dashpot Z is connected by a rod n by means of a pin and slot connection 0 to the arm 7:. carrying the rack 6
- the arm may be free to move the shutter a through an angle ofmore than 90 degrees when operating in either direction without engaging with the dashpot or until the shutter is in a position to be operatd on by gravity,
- An extension from the armature h is provided to operate a contact switch 1) which is capable of making metallic contact with two contacts 9. and 9
- the contact g is connected with a conductor 8* leading to one pole of a source of electricity and the contact g is connected to a conductor sleadin to one pole of the lamp e used for illuminating the element by night.
- a further conduetor s also connects the said lamp to'the opposite pole of a source of electricity.
- the contact switch p is permitted to engage the contacts due to the tension of a spring S, thus establishing a circuit through them and causing the lamp 0 to light when the conductors s, s are energized.
- the excitation of the coil 11 causes the element to be displayed, due to the shutter a beingremoved from the front of .the visual member 7'', and the excitation of the coil causes the element to disappear due to the shutter a covering said visual member.
- I provide a relay switch, the armature t of which is aaaaece capable of engaging a contact V connected to the coil 7' by a conductor V or alternatively engaging a contactW connected with the coil iby means of the conductors W 1 so construct the relay switch that it will not take up a position intermediate the contacts.
- the opposite ends of the coils j and i are connected together and to a conductor X so that when the conductors X, U, (the latter connected to armature t) are connected to a source of electricity, the movement of the armature t will alternatively connect the coils i and j to the conductor W or V and thus cause the excitation of the coil 21 or respectively.
- the said relay switch is adapted to be operated by two electromagnets Y and Z, the magnet Z being connected to the conductors Z ZY and the magnet Y to the conductors Y ZY.
- the relay coil Y is energized due to the conductors Y ZY being connected to the source of electricity, whereupon the switch armature t is attracted to cause contact to be made at W but no movement of the shutter 0, takes place until the conductors X, U are again energized, the power coil 71 being then energized to bring the shutter into the display position.
- each group of elements enables them to be set or actuated in a panel by panel method as described in the prior specification previously referred to so as to predetermine which elements shall actuate without actually causing movement of the shutters until the conductors X, U, are energized as by the closing of an auxiliary contact or contacts causing, as predetermined by the position of their individual relays, the elements upon one panel only or the elements upon the whole of the panels forming a sign to be energized and operated together.
- Fig. 2 represents an adaptation of the form of mechanism just described in Fig. 1, to operate a hemispherical shuttercomposed of two quarter spheres, aa representing the -shutters which are free to rotate through an angle of approximately 90 degrees on the bearings 6 12 small extensions 6 e on the shutters forming arms or levers for operating same.
- hh represents a rocking armature which may be actuated in a seesaw manner by coil 2' to close and by coil 7' to open the shutters.
- the armature 11.72. is provided with extensions 7070 which, when the armature is actuated by either of the coils 2'.
- the switch 10 is arranged to engage contact 9" when the shutters are open, so as to illuminate the lamp, and to engage contact 9" when the shutters are closed in such manner that an alternative circuit including a resistance p of equal ohmic and ampere capacity is substituted in the circuit for the lamp.
- Fig. 10 where the two way lamp switch 12 in Fig. 2 is denoted by p. so that it will be seen that any combination of lamps or resistances may be placed in series and after the actuation of the element switches the circuit switch DS may be closed, thus causing all the lamps that are in circuit-by the contacting of their switches-p )Fig. 2 to be illuminated.
- switches 10 By operating thecircuit switch DS to close later than, and to interrupt earlier than, the switches 10, such switches may be operated with no current flowing through their contacts so as to lengthen their life by avoiding burning or damage to their metallic contacts. It is also desirable that the switches p should make contact with the resistances R R and R before interrupting the lamp circuit and vice versa so that in the event of their being actuated with the current flowing through them they will never interrupt the main circuit.
- Auxiliary contacts energizing the actuating coils z and 7' may be connected and electrically actuated and operated from a controller as shown in Figs. 37 hereinafter described.
- FIG. 2 there is illustrated an element with a hemispherical shutter for the purpose of displaying or obscuring the visual member, but it is manifest that the motion of the armature k may by suitable mechanical means he I .adapted to operate any desired type of ele- --coils may be'made.
- ment shutter such as those illustrated in the previous specification comprising shutters of flat formation or double shutters or nests of shutters for producing efi'ects, etc., and although the interior'electrical connections both of the relay switch and power coils are described as connected in parallel, variations in the method of elec-' trically connecting the coils both of the Trelay and the actuating mechanism or power xamples 0 some such variations are illustrated by simple diagrams, Figs. 3 to '7, hereinafter described;
- the amount of power required to actuate the normal sized element mechanism and 1e lay coils being comparatively small, it is not commercially economical to construct their operating coils of such resistance as to enable them to be connected in parallel .upon a 100 or 200 volt circuit (such being the lowest usual pressures at which public supply companies supply electricity).
- the relay multi-color may be upon one panel twenty elements more or less and if connected in series the poten-' tial difiere'nce upon ,each pair of coils can be sufliciently low to enable the said coils to be wound with comparatively thick and low resistance wire, the total resistance of a se-' ries 'of, such elements being such that they may-be connected through the conductors X, U, (Figs. 1' and 2') to each other and the series so formed may then be connected directly to the electric supply companies mains.
- Fig. 3 represents one method of connecting the actuating coils of one element and Fig. 4 represents the connections when two or more of such elements are connected together in series.
- the source of electricity is represented by DY and the two power coils are connected together by means of the conductor X to the relay-armature t, the opposite end of the.
- FIG.-4" represent s two of such elements connected in series, DY representing the source of electricity and the circuit being from W to contact W of element B through the internal connections as described in Flg.
- Fig 1 The description of Fig 1 has shown that it is not necessary to ma1n-' tain excitation of thepower coils after the shutters have assumed the desired position, and deenergized by means of the switch DS which may be operated electromagnetlcally or otherwise so that the relay switches t may be moved to either of their contacts V or W after the switch DS :is opened, the said switch being required to establish contact only for a suflficient interval of time to permit the shutters to assume the desired positions.
- the switch DS which may be operated electromagnetlcally or otherwise so that the relay switches t may be moved to either of their contacts V or W after the switch DS :is opened, the said switch being required to establish contact only for a suflficient interval of time to permit the shutters to assume the desired positions.
- the relay switches t can again be moved to predetermine whether coils i or the coils 7' shall be energized, when the switch DS is again closed so that the mechanism operated by the said power coils will again assume or retain the position predetermined by the relay switches.
- Fig. 5 illustrates an element for operating with its actuating coils connected in parallel, in which the coil 71 causing the visual element to be displayed, when the relay switch t connects it to X but it can be caused to assume the non-display position by the energization of the circuit feeding the coil j without the actuation of the relay switch t.
- the coil j will then actuate mechanism to bring the shutter into the non-displaying position.
- the whole of the coils 3' through out a sign or groups may be connected together so that the operation of the auxiliary switch D8 will always cause the elements to assume the non-display position or clear the sign. It will be observed that when the auxiliary switch DS feeding conductor X is operated it will cause only the coils i to be energized, which are connected therewith by the relay switches t contacting W with X.
- Fig. 6 where it will be seen that the resistance R and coil 13 are altcrnatively connected by the relay switch t to the source DY through circuit switch DS, the resistance R preferably being of equal ohmic and ampere capacity to the coil 2', and may conveniently be contained within the element.
- the relay switches are first operated so that they are in the position shown in the drawing, connecting to one pole of the source DY through X to the contacts of switch DS through X to relay switch t then through contact Wand first coil a through conductor X second relay switch If and second contact W to the second coil 73, connected to the opposite pole of the source of electricity by conductor W so that current flows through both coils 'c' in series when the circuit switch DS is closed.
- the first relay switch t is moved to -engage contact RV and current will flow through resistance lit and then through X second relay switch t, coil 21 and conductor W the current being kept constant due to resistance R being in circuit as a substitute for *first coil 7: and it will be readily seen that according to the positions of relay switches 25 either, neither or both of the coils i may be energized when the switch DS is operated and that current flowing in the coils 11 or the resistance R (if of equal capacity to i) will be kept constant.
- the coils j used to cause non-display of the elements are connected in series through the auxiliary switch D8 to the source DY so that when said auxiliary.
- the resistance R may be located within the element in such position as 'to be usable to remove climatic effects fromthe shutter such as frost, snow or moisture.
- a number of elements so that their power coils operate in electrical parallel; two elements so connected are illustrated by Fig. 7, where it will be seen that one end of the winding of all the coils z and j are connected 'together by the conductor W to one pole of the electrical source DY, the other ends of the coils being connected respectively to the relay switch contacts W and V the relay switches It also being connected by means of conductors V and through switch DS to opposite pole of source DY.
- the two relay switches t contact with W and the auxiliary switch DS is closed, current will flow through the'two coils z, and with the relay switches upon the contact V and auxiliary switch DS closed, the two coilsy' will be energized.
- the relay switches 17 may be put in such position that when the auxiliary switch DS is closed the coil z upon one element and the coil 9' upon the other element may be energized.
- the provision of the switches DS permits the relay switches T to be operated with no electricity passing through their contacts, by which means it does not expose the contacts to the slight 5 carbonizing eflect that would otherwise be caused, thereby thus lengthening their life operate the relay switches with the current interrupted by the switches DS, as for certain effects upon the sign face it may be desirable to first close the switch DS and then operate the relay switches to cause the element shutters to operate, as and when the movements of the relay switches take p ace.
- each set of shutters may be actuated independently, and in such circumstances there should be provided mechanism capable of actuation by four impulses for each set of shutters, so that if for example an element were provided with a black shutter and a red shutter the red shutter being used as a visual member covering a white visual member, it is obvious that to display the white member, both the black and the red shutters should be operated to take up a position behind the white visual member and to produce the red element only the black shutter should be operated to such position.
- each set of shutters is operated by mechanism operating with four functions, so that a twocolored element would have eight functions and a three-colored element would have twelve functions and so on, adding four functions "for each color that the element was constructed to produce but for the purpose of this specification I regard such an element as a four function element.
- One relay may also be applied to supply a predetermining function to an element constructed in the manner illustrated by Fig. 5 of the specification previously referred to, in which the colors are successively displayed by the successive energization of the magnetic system, but it is preferred to provide the four independent functions for each color because the order in which the colors shall change can then be predetermined, whereas if. a relay is added to the successively energized single magnetic system, the colors can only appear one by one in succession determined by the construction of the element.
- the relay comprised within a multi-colored element with one magnetic coil, the successive excitation of which would cause the power coils to be successively selected in a step by step manner, but such an arrangement is open to the objection above stated, that the colors could only be caused to appear in the sequence determined by the construction of the said step by step relay.
- the element has been described as comprising a luminous member for displaying-in darkness, a non-luminous member to display when light falls upon the face of the sign together with a relay to determine if a individxia1'-'relement' shall display a not, it is obvious that the invention is not ner in which the actuating or electromagnetic systems of the relay switches (hereinafter called the relay coils) may be con nected to the composing switch or secondary relay.
- the relay coils the actuating or electromagnetic systems of the relay switches
- Fig. 8 The method of connecting in series and actuating a number of relay coilsfrom a composing key or collective'relay .is illustrated by Fig. 8, showing the series connections of the relay coils of six elements to a composing key I, so that such key will cause the sequence of the relay coils to be energized as may be predetermined by the disposition of contacts upon such key and consequent selective operation of the element relay switches connected therewith, thus predetermining the action of the desired ele ment shutters, so that it may operate when the power circuit is energized.
- the coils marked A to F represent the relay coils whose function as has already been explained is to actuate a switch to connect the non-display or clearing power coils, and the relay coils marked A to F are to connect the displaying power coils.
- the coils shown are all connected in series, both the coils actuating each relay together with the coils actuating the relay switches of the six other elements.
- Conductors numbered 1 to 13 connect to the coils in the manner shown and to the contacts of a multiple switch Z, which consists of a number of contacts carried by a common stem and insulated therefrom and from each other so that all the contacts may connect conductors 1-13 to 1 to 13", when the coil H is energized.
- Said switch is normally in the disconnecting position and by energization of the coil H connects conductors 1 to 13 and 1 to 13
- the coil H may be energized either from a panel selector or by the manual or electrical manipulation of a key or contact connecting it to a source of electricity.
- a compression spring S returns the switch 'Z to non-contacting position upon the deenergization of the coil H.
- the conductors 1 to 13 terminate at the contacts J upon the secondary relays or controller keyboard.
- the composing key I is provided with pairs 'of metallic fingers orcontacts M, N,f(), R arranged to shorteircuit pairs .1 of r the conductors at contacts J, but such pairs of fingers unless adjacent as N, O are not in electrical contact with others upon the key stem from which they are insulated.
- composing key I may be actuated manually or'by, he'excitation of a coil K to cause it to contact with the conductors at the points J at the same time connecting L, L" with one pole of a source of electricity,'the opposite pole of such source being connected to a conductor 13 as at 13 directly or through a second contact as indicated at L,L".
- the key I may beoperated to make its group of contacts.
- the current flowing through the coils which are shortcircuited will be of negligible quantity and not capable of sufliciently energizing the said coils to operate the relay switches.
- the current flowing through the path just described passes through the relay coils A, B, C, D, E 1?, thus causing them to operate or retain their relay switches in the required position.
- Each group of'rel'aycoils A to F is then separately actuated from the composin keys I as determined by the operation of the multi-contact switchZ placing the desired group of relays A to F into connection with the actuated compo'singkey I, so that any group of primary relays may be connected to any one of a plurality of keys I provided with dissimilar contacts so that any key I can actuate any group of elements T to Y.
- Relay operating coils connected in parallel and selectively operated by a composing key are illustrated by Fig. 10 in which the composing key I and the multiple'switch Z are operated in the manner previously de scribed with reference to Fig.
- actuation of the key I will cause relay coils A, C D, to operate its relay coils into the display position and coils B E and F to operate lnto the non-display position, so that upon'actuation of the composing key I and the multiple switch Z the individual primary relays assume the desired position whereby subsequent excitation of the circuit feeding the mechanism actuating the visual member will cause the display that hasbeen predetermined firstly by the key 1, although said key I is no longer contacting with conductors 1 to 12 and secondly by the individual primary relays.
- anelement comprising a shutter, separate primary electromagnetic devices adapted to move the shutter into positions of display and non-display, a relay including separate secondary electromagnetic devices adapted to determine which of said primary magnetic devices shall be energized, an alternative circuit connected to said primary electromagnetic devices, and means for operating said alternative circuit to subsequently energize the primary device deter- Y mined by said relay.

To all'whom it may concern:
Be it known that I, JAMEs PRIESTNALL NAYLOR, a subject of theKing of England, residing at Dulwich, in the county of Surin England, have invented certain new useful Improvements in Advertising or Signaling Apparatus, of'which. the following is a specification.
This invention relates to an advertising or signaling apparatus of the same class as described in the specification of my pendmg application, Serial No. 642,030 filed 2nd August, 1911, but in the present invention improvements have beenintroduced in the construction of the elements; in the method of electrically-connecting same; in the means for controlling the elements section by section; and in the arrangements of connections leading thereto for automatically actuating the elements.
The objects of these improvements have been to render the apparatus more versatile so that it is capable of reproducing devices, words, phrases, letters or signs in a larger variety and in a larger number of methods or order of appearance and capable of being controlled by fewer conductors, than is posgized.
In the principal form of the invention each individual element is so constructed that it possesses a double predetermining function and a double operating function, the predetermining function being operable without disturbing or actuating the visual section of the element, this predetermining function being provided by what may be called a primary relay and being controlled,
operated or set by asecondary relay or composing device. When it is stated that the elements are operable by four functions, four specific functions to each individual element are implied, namely 1. The setting of the primary relay switch to so affect the display mechanism that the Speciflcation of Letters Patent. Patentedjtpr. it, tart. Application filed April 14, 1914. Serial No. 831,751.
visual member of the element will operate to display when other devices" are energized.
tit":
2. The energization of the display mechanism to cause actual display of the visual member as predetermined'by the primary relay. y
3. The setting of the primary relay switch Gill to so affect the non-display mechanism that the visual members will cease displaying when other devices are energized.v
4. The energization of, the non-display mechanism to cause non-display of the visual element as predetermined by the primary relay.
These function of the composing devices or secondary relays. y I
In the previous specification above referred to, means, are disclosed whereby a, plurality of elements are controlled by the manipulation of composing keys or collective relays which might be deemed relays four functions do not include the operating the elements, but in the present invention I construct elements with individual relays introduced upon the conductors between the composing keys or secondary operating relays to directly and independently control the mechanism which actuates the visual section of each element, so that the composing devices may set the relays within or combined with the elements in 'the section by section manner disclosed in the said previous specification but without alfectin the visual member ofthe element, such vlsual meinber being subsequently caused to operate in a manner that has been predetermined by the primaryrelays, and the changing .of the display being effected independently of the excitation or manipulation of the composing devices or vice versa, solely by the energization of the actuating mechanism operating the visual sections of the elements through independent switching devices.
The invention also comprises means of constructing the electro-magnetic devices of both the-relay system and the actuating system in such a manner that the displaying and non-displaying functions of each element may each be connected in series and a group of such elements may also be connected either in electrical series, parallel or combinations of series and parallel.
In the'accompanying drawings, Figure l the back of the lamp e thus disclosing the is a sectional side elevation of one form of members for display when light falls upon.
its surface and such member is hereinafter termed the .non-luminous member and it may be provided with a lamp, preferably electric, capable'of illuminating or defining the, position of the said visual member during, night orfor the period that sufiicient light does not fall upon its surface to properly visualize it, such lamp being hereinafter termed "the luminous member, the term visual member being applied'to the members adapted for display both in light and darkness and the term sign being used to denote an assemblage of elements together with their cellular or other supporting back ground and" controlling means. The element andits means for direct actuation is constructed as a self-contained unit removable as a whole from its supporting back ground, such method of construction being adopted to facilitate manufacture, repair and transport as described in the previous specification aforesaid.
Alternative means of electrically connecting the element actuating devices are disclosed herein so that it is not necessary to move the relay into the non-displaying position before energizing the power circuit to cause the elements to assume the non-display position.
In order that the construction of the element may be comprehended, reference is directed to Fig. 1, which represents an'element with a hemispherical shutter a adapted to be rotated as by means of the pinion b and rack 6 upon the center d into a position at member f which may consist of white opal glass also of hemispherical form containing a lamp e and termed the visual member. The rack b is pivoted at 0 and has an extension consisting of a magnetic device or armature 71.. Located in proximity to said armature are the power coils i and j and if it is desired to display the visual member f, the power coil 71 is energized, thus attracting armature k and rotating the rack upon the pivot c, causing the shutter a to rotate upward and backward and assume a position behind said visual member, (the travel being limited as by a stop is), causing it to be the said shutter will not be easily brought to rest in any position between fully open and fully closed (in front of or behind the visual member) since gravity always tends tobrin it into one or the other extreme position, an
if power is applied to the armature h to cause the shutter to rotate through an angle of slightly more-than 90 degrees andrthen ceases, the force of gravity will cause the shutterv to continue its travel until it is arrested "by the stop 70, this action occurring both in displaying and causing non-display of the visual member, the force of gravity being used to practically lock or retain the shutter in a position in front of or behind the visual member f.
It will be understood that on the shutter striking the stop k noise may be emitted, and that during continued work damage may also be caused to the shutter at the point of contact, and in order to avoid these objections, I provide a dashpot 'Z for retarding the moving parts and preventing violent action. The plunger vm of the dashpot Z is connected by a rod n by means of a pin and slot connection 0 to the arm 7:. carrying the rack 6 The arm may be free to move the shutter a through an angle ofmore than 90 degrees when operating in either direction without engaging with the dashpot or until the shutter is in a position to be operatd on by gravity,
An extension from the armature h is provided to operate a contact switch 1) which is capable of making metallic contact with two contacts 9. and 9 The contact g is connected with a conductor 8* leading to one pole of a source of electricity and the contact g is connected to a conductor sleadin to one pole of the lamp e used for illuminating the element by night. A further conduetor s also connects the said lamp to'the opposite pole of a source of electricity. It will be seen that when the rack 6 travels downward in order to remove the shutter and disclose the visual member, the contact switch p is permitted to engage the contacts due to the tension of a spring S, thus establishing a circuit through them and causing the lamp 0 to light when the conductors s, s are energized.
So far as this description has gone it will be seen that the excitation of the coil 11 causes the element to be displayed, due to the shutter a beingremoved from the front of .the visual member 7'', and the excitation of the coil causes the element to disappear due to the shutter a covering said visual member. In order to determine or predetermine which of these coils shall be energized, I provide a relay switch, the armature t of which is aaaaece capable of engaging a contact V connected to the coil 7' by a conductor V or alternatively engaging a contactW connected with the coil iby means of the conductors W 1 so construct the relay switch that it will not take up a position intermediate the contacts. The opposite ends of the coils j and i are connected together and to a conductor X so that when the conductors X, U, (the latter connected to armature t) are connected to a source of electricity, the movement of the armature t will alternatively connect the coils i and j to the conductor W or V and thus cause the excitation of the coil 21 or respectively. The said relay switch is adapted to be operated by two electromagnets Y and Z, the magnet Z being connected to the conductors Z ZY and the magnet Y to the conductors Y ZY. It will be seen that if the conductors Z ZY are connected to a source of electricity, the relay armature t will be-brought upon the contact V and after cessation of current in said conductors the relay armature will remain on contact V but no energy will flow in the.
coils z', j and consequently no movement of the element shutter will take place until the conductors X, U are energized, whereupon the coil j is energized and, attracting the armature It, causes the shutter to move in the direction to obscure the visual member. When it is desired that the shutter should move in the opposite direction to disclose the visual member, the relay coil Y is energized due to the conductors Y ZY being connected to the source of electricity, whereupon the switch armature t is attracted to cause contact to be made at W but no movement of the shutter 0, takes place until the conductors X, U are again energized, the power coil 71 being then energized to bring the shutter into the display position.
The provision of the individual relay system t, W, V, Z, Y, to each group of elements enables them to be set or actuated in a panel by panel method as described in the prior specification previously referred to so as to predetermine which elements shall actuate without actually causing movement of the shutters until the conductors X, U, are energized as by the closing of an auxiliary contact or contacts causing, as predetermined by the position of their individual relays, the elements upon one panel only or the elements upon the whole of the panels forming a sign to be energized and operated together.
Fig. 2 represents an adaptation of the form of mechanism just described in Fig. 1, to operate a hemispherical shuttercomposed of two quarter spheres, aa representing the -shutters which are free to rotate through an angle of approximately 90 degrees on the bearings 6 12 small extensions 6 e on the shutters forming arms or levers for operating same. hh represents a rocking armature which may be actuated in a seesaw manner by coil 2' to close and by coil 7' to open the shutters. The armature 11.72. is provided with extensions 7070 which, when the armature is actuated by either of the coils 2'.
or j, convey their acquired 'motion to the a means of locking the shutter in either its' closed or open position. As in the mechanism represented in Fig. 1, the motion of thearmature and shutter maybe retarded by the introduction of the dashpot l, and similarly, the dispositionand action of the relay, locking s ring, switch, lamp and connection and the e ectrical conductors generally may be considered in efiect to be applicable to both operating mechanisms of the examples, Figs. 1 and 2.
In the example under consideration the switch 10 is arranged to engage contact 9" when the shutters are open, so as to illuminate the lamp, and to engage contact 9" when the shutters are closed in such manner that an alternative circuit including a resistance p of equal ohmic and ampere capacity is substituted in the circuit for the lamp.
The particular utility of this arrangement is that it enables the lamps in groups of elements to be connected in series, permltting low (1?. and low voltage metallic lamps to be used. The manner in which a number of lamps are connected together is shown by Fig. 10 where the two way lamp switch 12 in Fig. 2 is denoted by p. so that it will be seen that any combination of lamps or resistances may be placed in series and after the actuation of the element switches the circuit switch DS may be closed, thus causing all the lamps that are in circuit-by the contacting of their switches-p )Fig. 2 to be illuminated. By operating thecircuit switch DS to close later than, and to interrupt earlier than, the switches 10, such switches may be operated with no current flowing through their contacts so as to lengthen their life by avoiding burning or damage to their metallic contacts. It is also desirable that the switches p should make contact with the resistances R R and R before interrupting the lamp circuit and vice versa so that in the event of their being actuated with the current flowing through them they will never interrupt the main circuit. There may be a multiplicity of switches DS preferably of equal number to the switches causing actuation of the display mechanism of the elements, so that the illumination may be caused inlike sequence. It will .be' understood that the switches DS Fig. 10, may remain in the off position during the day tlme or other period that it is not desired that self illumination element but when it is desired to arrange.
elements in a monogram by dispensing with these connections, it is possible to pack them more closely together, and there has therefore been devised the alternative methodof connecting the terminals as from X, U, ZY, Z 8 etc., to a flexible conductor X (Fig. 2) which is connected to a plug X containing as many contact pins X as there are terminals or element conductors to be connected. This plug engages with a counterpart and by irregular disposition of the pins it is impossible to incorrectly insert them into their counterparts so that by the provision of the said plug the removal and replacement of an element and its correct connection is greatlyfacilitated.
Auxiliary contacts energizing the actuating coils z and 7' may be connected and electrically actuated and operated from a controller as shown in Figs. 37 hereinafter described.
In the example above referred to (Fig. 2) there is illustrated an element with a hemispherical shutter for the purpose of displaying or obscuring the visual member, but it is manifest that the motion of the armature k may by suitable mechanical means he I .adapted to operate any desired type of ele- --coils may be'made.
ment shutter such as those illustrated in the previous specification comprising shutters of flat formation or double shutters or nests of shutters for producing efi'ects, etc., and although the interior'electrical connections both of the relay switch and power coils are described as connected in parallel, variations in the method of elec-' trically connecting the coils both of the Trelay and the actuating mechanism or power xamples 0 some such variations are illustrated by simple diagrams, Figs. 3 to '7, hereinafter described;
The amount of power required to actuate the normal sized element mechanism and 1e lay coils being comparatively small, it is not commercially economical to construct their operating coils of such resistance as to enable them to be connected in parallel .upon a 100 or 200 volt circuit (such being the lowest usual pressures at which public supply companies supply electricity). There the source. The relay multi-color may be upon one panel twenty elements more or less and if connected in series the poten-' tial difiere'nce upon ,each pair of coils can be sufliciently low to enable the said coils to be wound with comparatively thick and low resistance wire, the total resistance of a se-' ries 'of, such elements being such that they may-be connected through the conductors X, U, (Figs. 1' and 2') to each other and the series so formed may then be connected directly to the electric supply companies mains.
Fig. 3 represents one method of connecting the actuating coils of one element and Fig. 4 represents the connections when two or more of such elements are connected together in series. In Fig. 3 the source of electricity is represented by DY and the two power coils are connected together by means of the conductor X to the relay-armature t, the opposite end of the.
shortcircuited, and that current will flow,
from DY through the wire V to the .switch If by the conductor X through the winding of coil 2' and conductor W back to the opposite pole of the source so that the coil 2' will be energized, coil 7', being practically nonmagnetic, owing to the shortcircuiting eflect of the relay switch t. If the relay switch 25 is moved so as to contact with W, the coil '5 will then be shortcircuited and when energy flows from the source DY it will then pass by the conductorV to coil j returning by X through t, W and W to the opposite pole of switch t being so constructed as not .to remain in a position intermediate between V and W, it therefore fol lows that there will always be a shortcircuit on either the coil 2' or 7', determined by the coils z" and y'jare of equal resistance, the ciractuating or power coils by z and 3'. These cuit from W through the relay switch and coils to V always be V of practically equal resistance.-
'Fig.-4"represent s two of such elements connected in series, DY representing the source of electricity and the circuit being from W to contact W of element B through the internal connections as described in Flg.
3, to conductor WV connecting with the contact V and also to the contact W in element B and from contact W to the o posite ole of the source of electricity. N bw if 0th the relay switches t are respectively in contact with V current 'will flow from the source DY through W to coil cf (element B ture Z. .If both relay switches 27 are caused to contact withtheir 'conductors W, the two coils 7' will be energlzed, and if one switch contacts with V and the other contacts with. W, and coil 71 will be energized upon one ele- .'ment and the coil energized upon the other.
It will loo-readily seen that if these coils actuate the shutter mechanism as illustrated in Figs. 1 or 2, this method of connection therefore the conductor V is energized v will enable the elements tobe operated in series, and it is obvious that as many of such elements as may be desired may be connected in series in this manner, and. as the relay switch If is so constructed that it cannot take up an intermediate position out 'of contact with X, W or K, V there will always be in circuit in each element either the coil 11 or Pluralities of such elements connected in series will therefore be of constant resistance irrespective of the relay switch If being upon contacts W or V. The description of Fig 1 has shown that it is not necessary to ma1n-' tain excitation of thepower coils after the shutters have assumed the desired position, and deenergized by means of the switch DS which may be operated electromagnetlcally or otherwise so that the relay switches t may be moved to either of their contacts V or W after the switch DS :is opened, the said switch being required to establish contact only for a suflficient interval of time to permit the shutters to assume the desired positions.
During the periodic interruption of circuit V W, the relay switches t can again be moved to predetermine whether coils i or the coils 7' shall be energized, when the switch DS is again closed so that the mechanism operated by the said power coils will again assume or retain the position predetermined by the relay switches.
Fig. 5 illustrates an element for operating with its actuating coils connected in parallel, in which the coil 71 causing the visual element to be displayed, when the relay switch t connects it to X but it can be caused to assume the non-display position by the energization of the circuit feeding the coil j without the actuation of the relay switch t. This is accomplished by connecting one end of the display coil i to one pole of the source of electricity DY and the other end of the coil to the contact W and thence through relay switch If and conductor X through the circuit switch DS to the opposite pole of the source, so that when the relay switch is in the position shown and' the circuit switch assesses DS is closed and D53 is open, the conductors W and X will then be energized and "the shutter will move to the displayed position. When it is desired that the element should assume the non-displaying osition the conductor V is energized by t e closing of the switch D8 the coil 2' being normally deenergized until the switch DS is closed, so
that the coil j will then actuate mechanism to bring the shutter into the non-displaying position. The whole of the coils 3' through out a sign or groups may be connected together so that the operation of the auxiliary switch D8 will always cause the elements to assume the non-display position or clear the sign. It will be observed that when the auxiliary switch DS feeding conductor X is operated it will cause only the coils i to be energized, which are connected therewith by the relay switches t contacting W with X.
. Elements internally connected in aman- .ner similar to that illustrated by Fig. 5, may
by the addition of an internal resistance or other alternative path be connected, and operated in groups connected in series, the method whereby this may be accomplished being illustrated by Fig. 6,where it will be seen that the resistance R and coil 13 are altcrnatively connected by the relay switch t to the source DY through circuit switch DS, the resistance R preferably being of equal ohmic and ampere capacity to the coil 2', and may conveniently be contained within the element. When it is desired that coils 11 in both elements shall be energized, the relay switches are first operated so that they are in the position shown in the drawing, connecting to one pole of the source DY through X to the contacts of switch DS through X to relay switch t then through contact Wand first coil a through conductor X second relay switch If and second contact W to the second coil 73, connected to the opposite pole of the source of electricity by conductor W so that current flows through both coils 'c' in series when the circuit switch DS is closed. If it is desired that only the second coil 71 should be energized, the first relay switch t is moved to -engage contact RV and current will flow through resistance lit and then through X second relay switch t, coil 21 and conductor W the current being kept constant due to resistance R being in circuit as a substitute for *first coil 7: and it will be readily seen that according to the positions of relay switches 25 either, neither or both of the coils i may be energized when the switch DS is operated and that current flowing in the coils 11 or the resistance R (if of equal capacity to i) will be kept constant. The coils j used to cause non-display of the elements are connected in series through the auxiliary switch D8 to the source DY so that when said auxiliary. switch is closed all the coils j forming the series will be energizd, thusbringing all the shutters displayplayed by closing theswitch D S for a short interval and the device can be caused to appear and disappear. successively by the alternate action only of the switches DS and DS.
The resistance R may be located within the element in such position as 'to be usable to remove climatic effects fromthe shutter such as frost, snow or moisture.
Where a supply of low voltage is available or other circumstances may render such a course desirable, there may be connected a number of elements so that their power coils operate in electrical parallel; two elements so connected are illustrated by Fig. 7, where it will be seen that one end of the winding of all the coils z and j are connected 'together by the conductor W to one pole of the electrical source DY, the other ends of the coils being connected respectively to the relay switch contacts W and V the relay switches It also being connected by means of conductors V and through switch DS to opposite pole of source DY. With the element connected in this manner, if the two relay switches t contact with W and the auxiliary switch DS is closed, current will flow through the'two coils z, and with the relay switches upon the contact V and auxiliary switch DS closed, the two coilsy' will be energized. The relay switches 17 may be put in such position that when the auxiliary switch DS is closed the coil z upon one element and the coil 9' upon the other element may be energized.
Elements with internal connections may also be connected in series as in Fig. 7.
It will be obvious that other methods of connection of the operating coils or groups may be adopted such as connecting in series groups already in parallel, thus forming a series parallel but the systems above described are found most suitable for the purpose in view.
In the foregoing diagrams, the provision of the switches DS permits the relay switches T to be operated with no electricity passing through their contacts, by which means it does not expose the contacts to the slight 5 carbonizing eflect that would otherwise be caused, thereby thus lengthening their life operate the relay switches with the current interrupted by the switches DS, as for certain effects upon the sign face it may be desirable to first close the switch DS and then operate the relay switches to cause the element shutters to operate, as and when the movements of the relay switches take p ace.
When an element is provided with more than one set of shutters as with color changing elements, each set of shutters may be actuated independently, and in such circumstances there should be provided mechanism capable of actuation by four impulses for each set of shutters, so that if for example an element were provided with a black shutter and a red shutter the red shutter being used as a visual member covering a white visual member, it is obvious that to display the white member, both the black and the red shutters should be operated to take up a position behind the white visual member and to produce the red element only the black shutter should be operated to such position. Again if it were desired to display at will either the White or the red visual section each set of shutters is operated by mechanism operating with four functions, so that a twocolored element would have eight functions and a three-colored element would have twelve functions and so on, adding four functions "for each color that the element was constructed to produce but for the purpose of this specification I regard such an element as a four function element.
One relay may also be applied to supply a predetermining function to an element constructed in the manner illustrated by Fig. 5 of the specification previously referred to, in which the colors are successively displayed by the successive energization of the magnetic system, but it is preferred to provide the four independent functions for each color because the order in which the colors shall change can then be predetermined, whereas if. a relay is added to the successively energized single magnetic system, the colors can only appear one by one in succession determined by the construction of the element. It is also possible to provide the relay comprised within a multi-colored element with one magnetic coil, the successive excitation of which would cause the power coils to be successively selected in a step by step manner, but such an arrangement is open to the objection above stated, that the colors could only be caused to appear in the sequence determined by the construction of the said step by step relay.
Although the element has been described as comprising a luminous member for displaying-in darkness, a non-luminous member to display when light falls upon the face of the sign together with a relay to determine if a individxia1'-'relement' shall display a not, it is obvious that the invention is not ner in which the actuating or electromagnetic systems of the relay switches (hereinafter called the relay coils) may be con nected to the composing switch or secondary relay. V
The method of connecting in series and actuating a number of relay coilsfrom a composing key or collective'relay .is illustrated by Fig. 8, showing the series connections of the relay coils of six elements to a composing key I, so that such key will cause the sequence of the relay coils to be energized as may be predetermined by the disposition of contacts upon such key and consequent selective operation of the element relay switches connected therewith, thus predetermining the action of the desired ele ment shutters, so that it may operate when the power circuit is energized.
The coils marked A to F represent the relay coils whose function as has already been explained is to actuate a switch to connect the non-display or clearing power coils, and the relay coils marked A to F are to connect the displaying power coils. The coils shown are all connected in series, both the coils actuating each relay together with the coils actuating the relay switches of the six other elements. Conductors numbered 1 to 13 connect to the coils in the manner shown and to the contacts of a multiple switch Z, which consists of a number of contacts carried by a common stem and insulated therefrom and from each other so that all the contacts may connect conductors 1-13 to 1 to 13", when the coil H is energized. Said switch is normally in the disconnecting position and by energization of the coil H connects conductors 1 to 13 and 1 to 13 The coil H may be energized either from a panel selector or by the manual or electrical manipulation of a key or contact connecting it to a source of electricity. A compression spring S returns the switch 'Z to non-contacting position upon the deenergization of the coil H. The conductors 1 to 13 terminate at the contacts J upon the secondary relays or controller keyboard. The composing key I is provided with pairs 'of metallic fingers orcontacts M, N,f(), R arranged to shorteircuit pairs .1 of r the conductors at contacts J, but such pairs of fingers unless adjacent as N, O are not in electrical contact with others upon the key stem from which they are insulated. The
composing key I may be actuated manually or'by, he'excitation of a coil K to cause it to contact with the conductors at the points J at the same time connecting L, L" with one pole of a source of electricity,'the opposite pole of such source being connected to a conductor 13 as at 13 directly or through a second contact as indicated at L,L". When the conductors 1l3 are connected to 1 13 by means of the multiple switch, the key I may beoperated to make its group of contacts. at J and current will then flow from a source of electricity through the switch contacts L, L, to the conductor 1 then by the shortcircuiting contacts M upon the key I to the conductor 2 and thus through the multiple switch Z to the conductor 2, thence to the coil A of the element T to the conductor 3 through the coil B to the element U, to the conductor 4, then through 4' to contact N to the shortcircuitthrough the conductor 6*.
ing contact 0 through the multiple switch to 6 and thence through the coil ()to 7, through the multiple switch and conductor 7 through the shortcircuiting contacts 1? to conductor 8, through the multiple switch to 8, through coil D to coil E, thence to conductor 10, through multiple switch to 10, through the shortcircuiting contact Q to the conductor 11*, through multiple switch to 11, through coil F, to the conductor 12, through multiple switch to 12 and through shortcireuiting contact R to the opposite pole 13 of the same source of electricity supplying the contacts L, L It will be seen that current willnot flow along conductors 3 9*, due to there being no connection established upon the contacts J attached thereto. By suitably proportioning the resistance of the conductors, coils and contacts, the current flowing through the coils which are shortcircuited will be of negligible quantity and not capable of sufliciently energizing the said coils to operate the relay switches. The current flowing through the path just described passes through the relay coils A, B, C, D, E 1?, thus causing them to operate or retain their relay switches in the required position. Assuming the coils A to F are to operate the relay switches so as to connect the displaying power coils of their elements, and A to F are arranged to connect the clearing power coils or disconnect the display coils, by reference to Figs 37, it will be seen that elements T, V and 'W will have their relays assume a position to predetermine display, and elements U, K and Y will predetermine non-display, when the composing key I is operated. To display one element only, all the non-displa coils 'and it will be understood thatthenumber of groups of coils as A to F may be extendedas may be desired as also the number of coils in each group and also the number of comto' secure by Letters Patent of the United posing keys I". Each group of'rel'aycoils A to F is then separately actuated from the composin keys I as determined by the operation of the multi-contact switchZ placing the desired group of relays A to F into connection with the actuated compo'singkey I, so that any group of primary relays may be connected to any one of a plurality of keys I provided with dissimilar contacts so that any key I can actuate any group of elements T to Y. Relay operating coils connected in parallel and selectively operated by a composing key are illustrated by Fig. 10 in which the composing key I and the multiple'switch Z are operated in the manner previously de scribed with reference to Fig. 8, but in this instance the contacts M to R upon said composing or secondary relay key I, are in' metallic contact with each other as by means of the key stem and such key when depressed is connected to one pole of the source of electricity through contacts L", L. When the multiple switch Z and the composing key I are operated 1 together, current will flow through L to L, thence to the stem of the key I through the contacting tongues M to R", then to the conductors with which they contact and the tongues of the multiple switch Z of the relay selective coils A to F and then to the opposite pole of the source 13, thus causing the relay switches to take up a position predetermined by the dis position of the contacts upon the key I. In the example given, actuation of the key I will cause relay coils A, C D, to operate its relay coils into the display position and coils B E and F to operate lnto the non-display position, so that upon'actuation of the composing key I and the multiple switch Z the individual primary relays assume the desired position whereby subsequent excitation of the circuit feeding the mechanism actuating the visual member will cause the display that hasbeen predetermined firstly by the key 1, although said key I is no longer contacting with conductors 1 to 12 and secondly by the individual primary relays.
In' the two examples illustrated in Figs. 8
and 9, which is considered to be the most versatile arrangement, is shown namely the ability of the composing key to select the relay coils required to dlsplay and the relay coils not required to display, so that subsequent energization of the mechanism operatingthe visual members causes certainlof the elements to display, certain of the elements that are already displaying to assume the non-displa ing position, and certain of the elements will have no motion imparted to them. By this means one character that may be already displayed may be caused to dissolve into another character.
