UNITED STATES PALITENT oFFio I THOMAS R. CLARK. OF BRADFORD, PENNSYLVANIA.
DISPLAY APPARATUS.
1 ,oomaa.
To all whom it may concern:
lie it known that I, Tnoims It. CLARK, citizen of the United States. residing at Bradford. in the county of McK an and State of Pennsylvania, have invented certain new and useful Improvements in Display Apparatus; and I do hereby declare the following to be a full, clear, and-exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to provide a display apparatus for exhibiting certain signs or characters carried upon a movable web or sheet,- and it has for its object provision of means whereby the web is correctly and accurately operated in a desired manner from a prime motor, without reference to the extent or speed of movement of the prime motor, or of the vehicle upon which the apparatus may be installed, and the provision of means whereby the desired actuation of the web is more certainly obtained when the device is employed as a station indicator, notwithstanding carelessness or inadvertence on the part of the operator, and of means whereby the device when used as a station indicator on a moving vehicle may be more readily adapted to the particular conditions under which'the vehicle is operated.
In carrying out my invention I provide an actuating means for the web, which I term for convenience the prime motor, which 1s totally disconnected from the web at all times'except during the actual move- 'ment of the web thereby, and I control the duration of actuation of the web by the web itself independently of the speed or extent of movement of the prime motor. The prime motor may be any suitable source of power, and may operate continuously or intermittently provided'it is in operation at the time-or timesthat the web is to be actuated. For example, I may employ as the prime motor a shaft, operatively connected with and driven from a suitable source of power and where the apparatus is carried on a moving vehicle this shaft maybe driven from the axle of the vehicle or from the motor thereof, or from a motor operated by Specification of Letters Patent.
Application filed August 9, 1909. Serial No. 512,021.
Patented 3 also consist of a motor located within the casing of the apparatus, and may be an electric motor, a spring actuated motor or other type of motor as preferred. v 1
In the embodiment of my invention which I have selected for purposes of illustration, I have shown it applied to a station indicator to be carried on a moving car or other vehicle, and the prime motor here shown is an electric motor mounted within the casmg of the apparatus, and arranged to receive current either from the same source as the motors of the vehicle, or from a storage or other battery carried on the same.
In the accompanying drawings which illustrate one form in which I have contemplated embodying my invention, Figute 1 represents a front view of the indicator. Fig. 2 is a front elevation with the front plate removed, and the indicating web also removed for greater clearness. Fig. 3 is a vertical transverse sectional view of the apparatus on line 33 of Fig. 2. Fig. 4 is a similar section on line 44 of Fig. 2. Fig. 5 is a detail of the reversing lever and it's connected parts. Fig. 6 is a diagrammatic view illustrating one arrangement of electric circuits. Fig. 7 is a similar view showing a modified arrangement of circuits.- Figs. 8, 9 and 10 aredeta'il views of a switch illustrated in Fig. 7, for preventing an improper actuation of the apparatus. Fig. 11 is a detail partial view of the indicating web. Fig. 12 is a detail view of the locking plate for the reverse lever.
In the drawings 1 represents an inclosing casing provided with a display front 2, provided with transparent portions 2, 2 for displaying simultaneously the name of a street or station, and adjacent thereto an advertisement as indicated in Fig. 1. I prefer to form the display front of a sheet of glass having portions covered with opaque finaterial leaving the display openings 2, 2 but the result may be accomplished in other ways.
3 represents a flexible web of any suitable material carrying the characters or signs to the top and bottom of the display front, and
which are also detachably mounted in the casing. Each of the winding rolls is preferably provided with a guiding flange 8 at each end, and with gudgeons 9 and 10 projecting from opposite ends of the rollers. The gudgeon 9 of each roller is preferably provided with a conical end portion or center 11, which engages a corresponding conical recess in a yielding plate 12, contained within a bearing sleeve 13, secured to the side walls of the casing or other support, in any suitable manner, and having a spring 14 in rear of said yielding plate, the sleeve 13 having at its outer end an annular inturned retaining flange 15 to retain the'plate 12 within the same when the roller gudgeo-n is removed from engagement therewith.
The gudgeon 10 at the opposite end of each of the rollers 4 and 5 is adapted to enter a recess in a stub shaft 16 mounted in a bearing sleeve 17 secured to the side wall of the casing, or other support, and the gudgeon 10 and shaft 16 are also provided with interlocking driving devices, consisting in this instance of a transversely disposed pin 18, the ends of which project laterally from the gudgeon, and enter recesses in the stub shaft, when the roller is in operative position. Each of the stub shafts 16 is provided with driving mechanism, in this instance, a worm wheel 20, secured thereto, so that when the rollers 4: and 5 are in operative position, one or the other may be driven by applying'power to its respective worm wheel 20.
The guide rollers 6 and 7 are mounted in the casing in a mannersimilar to the winding rollers, so as to be readily removable therefrom. One of these guide rollers (in this instance the guide roller 6) is constructed to form part of contact mechanism as hereinafter described, and to that end the said roller is provided'with a metallic surface 19, consisting preferably of a brass tube which is placed in electric connection with the electric circuits by which the operation of the device is controlled, in any suitable manner. In this instance I have shown a spring brush or strip 21 of conducting material secured to the casingand provided with a binding post 22, to which a wirecan be connected. In conjunction withthe conducting and guiding roller 6 I employ one or more contacts which normally bear upon the surface of the web upon said roller and are adapted to establish an electric connection with the roller, at intervals, through certain means, with which the web is provided, said means consisting preferably of holes cut in the web, although I may employ a metallic device, such as a rivet or button extending through the web, or other means for establishing an electric connection between the said contact or contacts and the roller. In this instance I emplo two of such contacts 23 and 24 located a jacent to the opposite ends of the roller 6, and a central contact 25, said contacts bein alike in construction and each consisting o a spring arm carrying a friction roller, for the purpose of reducing the friction on the' web. The operation of these contacts will be hereinafter fully explained.
30 represents the prime motor, consisting in this instance, of an electric motor, the shaft of which is provided with the female member 31 of a cone clutch.
36 represents the driving shaft for the winding mechanism, which is mounted in a suitable bearing or bearings, in axial alinement with the motor shaft.
35 represents the female member of a cone clutch, which is stationary and is mounted upon or secured to the drive shaft hearing or other stationary part of the mechanism.
33 is a movable clutch sleeve mounted on a key or feather on the driving shaft 36, and provided at its opposite ends with male cone clutch members 32 and. 34 respectively to engage the female members 31 and 35. When the clutch sleeve is shifted to cause the engagement of the clutch members 31 and 32, the prime motor will be coupled to the driving shaft, and when the clutch sleeve is shifted in the opposite direction the members 31 and 32 will be released and the members 34 and 35 engaged, thus acting as a brake to stop the driving shaft, and hold it locked against accidental rotation.
I do not limit myself to the exact. .construction of clutch mechanism shown and described, but I find this construction to be compact, and advantageous, and it forms a combined clutch .andjb'rake mechanism.
Mechanism is also provided for transmitting motion from the driving shaft to either of the worm wheels 20, for driving the winding rollers and causing the web to travel in either direction. 'The mechanism which I prefer to employ is illustrated in detail in Fig. 5 and is constructed as follows. 37 represents a driving miter gear on the driving shaft 36,- which engages a miter gear 38 on a swinging shaft 39 mounted in a racket 40, which is pivoted concentrically with the axis of the driving shaft and is preferably provided with a sleeve 41, engagmg a ortion of the drive shaft bearing or the drive shaft itself. The swinging shaft 39 is provided with a worm 42 which can be move into engagement with either of the worm wheels 20, 20, for driving the winding rollers; and the sleeve 41 of the bracket 40 is rovided with a revolving arm 43, extendmg through a slot 44 in the casing (see Figs. 4 and 12)"and provided with a locking plate 45, having a slot therein provided with lateral notches -16, 47 and 48, into which the arm 43 will seat itself, said arm being preferably made of spring material, so as to lock said arm and hold the worm 42 in engagement with either of worm wheels 20, or in a neutral or out position, as desired.
50 represents a solenoid provided with a longitudinally movable core piece 51, of soft iron to which is preferably secured an extension 52 of non-magnetic metal, such as brass, which is pivotally connected by a loose joint with a clutch and brake lever"53 pivoted at 54 and provided at its upper end with a yoke 55 engaging the movable clutch sleeve The core piece 51 is provided with a retracting spring 57, the outer end is adjustably secured to a bracket 59 by means of a threaded rod 58 and nuts 60, 60 so that the tension of the spring can be adjusted, and said spring acting through the core piece 51 and lever 53 normally holds the clutch member 34 in engagement with stationary clutch member 35 .and holds the driving shaft locked. As one of the winding rollers is ordinarily in engagement with the driving shaft the web is thus held normally locked against accidental movement and out of engagement with the prime motor. When the solenoid is energized, as hereinafter explained, the core piece 51 is moved in the direction of the arrow, Fig. 2, thus disengaging clutch members 34, 35 and engaging clutch members 31, 32, and con- 'necting the driving shaft with the prime motor which may be continuously operated,
or simultaneously energized, as before stated' In the present instance the motor 30 is energized simultaneously with the solenoid, by means of an actuating switch, operated manually or otherwise, and in order to cut out said switch immediately after its actuation, I prefer to provide a cut out switch, one member of which is the lower end 56 of the lever 53,.and the other member of which comprises -two normally separated contacts 61, 61, insulated from each other, between which the part 56 is forced by the actuation of the solenoid, thus cutting out the actuating switch as hereinafter explained.
Referring now to the dia am of the electric connections shown in ig. 6, 7O represents the battery or other source of electricity for. actuating the prime motor and the solenoid. The motor 30 and solenoid 50 are connected in parallel with the battery 70, by wires 71 and 72, the actuating switch being in the circuit and here shown in wire ducting surface 19 of web guiding roller 6, and a wire 75 connects wire 71 (at a point between the motor and solenoid) with a switch 80, being connected to the central post 77. A wire 81, leads from one of the switch contacts 78 to the contact 24, and a wire 82 leads from the other switch contact to the contact 23. It is understood that the web normally intervenes between contacts 23 and 24 and the roller 6, preventing the closing of the circuit thereth'rough. Supposing the switch lever 83 to be in the position shown, on the contact 79, the operation will be as follows:
As the car or other vehicle approaches a station, the actuating switch 65 is operated in any desired way either automatically or manually. In this instance it is shown as designed to be operated manually. The operation of the switch closes the circuit through the motor and solenoid and actuates the solenoid core 51. The motor will instantly start, and the lever 53 will be by the motor and driving mechanism until the next contact means (in this instance an aperture cut in the web, adjacent to its edge) permits the contact 23 to engage the contact surface of guide roller 6, when the solenoid is short circuited through wires 75 and 76 and the spring 57 retracting the core piece breaks the motor'circuit by disengagmg the part 56, of lever 53 from contacts 61. The return movement of the lever 53 shifts the clutch sleeve into engagement with the stationary clutch member, and simultaneously disconnects the driving shaft from the motor and alsoacts as a brake to stop the driving shaft and hold it locked, until the device is again operated.
In order to insure the proper operation of the device, the next time the actuating switch is operated, and to avoid a spark which might injure the web and destroy the apparatus, I adjust the spring 57 in such manner that the driving shaft is not stopped instantly, but is permitted to make a sufficient movement to carr the aperture in the web beyond the contact 23 (or 24) and separate said contacts from the roller '6, before being stopped. For this purpose the aperture (or other contact means) must be located a little in advance of the point at which the web is to be stopped,
stop the film to show accurately the characters thereon. It is for this reason that I prefer to employ the two contacts and 24, each operating in conjunction with a separate set of holes (or other means for establishing an electrical connection with the tending transversely of the film, and indicated at :1: in dotted lines, for greater clearness. The switch 80 can be operated to throw the contact 23 or 24 into circuit according to the direction in which the web is being moved. The adjustment of the spring 57 regulates the distance which the web overruns to carry the aperture in the web beyond the contacts 23, or 24 directly by carrying the pressure or force with which the contacting frictional surfaces 334i and 35 are brought into contact and held in contact, when the solenoid is deenergized and releases its core, so that the resulting braking action of said friction surfaces will stop the web more or less quickly. In practice the spring 57 is adjusted to secure just the amount of over-running of the web which is desired.
84; represents a third contact point on the switch 80 which is connected by a wire" to the central contact 25 engaging the roller (3.-
The web 3 is provided adjacent to each end with a single aperture (or other contact device) 25 to pass between the contact 25 and roll (3. The object of this arrangement is to provide for the complete reversal of the web from one winding roller to the other. In some instances, as where an indicator is used at each end of the car, and for indicating the stations in one direction only, it is desirable to reverse the web at the end of a trip so that it will be ready for use on the next trip in the same direction. In such case itis only necessary for the operator to operate the reverse lever 43, and turn the switch 80 to the point 84 marked reverse, and operate the actuating switch when the web will be completely rewound on the roller from which it has just been unwound, until the aperture 25* adjacent the end from which it is being wound permits the contact 25 to make contact with roller 6 and thus stops the film in position tobe again intermittently operated as before, and thus avoiding the tedious rewinding of the web by hand.
In Fig. 7 I have shown a slightly modified diagram of the circuits introducing a modified form of actuating switch which I may employ to render the operation of my apparatus more certain. In the arrangement shown in Fig. 6, the operator might carelessly keep the actuating switch (35 closed until after the device had been operated and thus produce a second operation of the de vice immediately thereafter. In order to prevent the possibility of such happening, I may employ the arrangement of circuits shown in Fig. 7 in which 7 0 reprsents the source of electricity, 71 the lead wire connecting the motor 30, and solenoid 50 in parallel, 72 the other lead wire connected to the movable contact arm 90 of the modified form of actuating switch illustrated in detail in Figs. 8, 9 and 10.
The arm 90 is provided with a contact 91 adapted to engage a contact 92, connected by wire 72 with a magnet 93, thence by wire 72 to a signal bell, which may or may not be employed, thence by wire 72 to the solenoid and motor. The switch arm 90 is provided with an armature which is attracted and held by magnet 93, when the circuit is closed. Wires 7 5 and 7 6 are connected to the switch 80 and contact 21, as in Fig. 6, but in this instance the contact of any one of the contacts 24', 25 or 26 with roller 6 serves to short circuit the magnet 93 and release the switch arm 90, which is retracted to normal position by a spring 94, thereby breaking the main circuit through the motor and solenoid.
The actuating switch is provided with an actuating arm 95, pivoted on the same stud as, and above the switch arm 90 and provided with a pivoted detent 96, for engaging and actuating arm 90. This detent is held in operative or inoperative posit-ions by a spring 97 which engages fiat faces on the portions of the detent adjacent to the pivotal connection, so that when the actuating arm 95 has moved the switch arm 90 until the armature carried thereby engages the magnet poles,- the further movement of arm 95 will disengage the detent from the actuating arm, leaving it free to return at the proper tlme. As the actuating arm 95 returns under the influence of a separatearranged for certain of said stations only as express stops and use the switch S0 to switch in one or other of said contacts according as the vehicle is used for local or express service. I may also use the device for the display of advertising matter only, in which case the device' may be stationary, or mounted on a vehicle s preferred and the actuating switch may be operated by hand, or in any other desired manner.
