EXHIBITING MECHANISM.

To all 't0/0m 'it may concern Be it known that I, CLARENCE M. Evn- Lc'rn, a citizen of the United States, residing at River Forest, in the county ol Cool: and State oit Illinois, have invented a new and useful Exhibiting Mechanism, of which the following is a specification.

The present invention relates to improvements in exhibiting mechanisms, the primary object of the invention being the provision of a mechanism for automatically exhibiting one sign at a time, said signs being provided with indications upon two sides thereof and being displayed as a pendant and in an obstructed view by the mechanism, said mechanism being operably connected to means, whereby the pendant sign is removed and the next succeeding' sign in a magazine is displayed, the removed sign being placed at the rear of and in the magazine to be again at the proper time exhibited.

A further wobject of the present invention is the provision of a novel sign exhibiting mechanism, which will operate with any number of signs, according to the size of the magazine, the same being provided with a novel form of removing and elevating mechanism, whereby the previously exhibited pendant sign is removed and placed at the rear and within the magazine while the Iii-st sign in the magazine is automatically released and placed in exhibiting position.

A still further object ol the present invention is to provide a novel -form ol sign engaging mechanism carried by the elevating mechanism which after releasing a sign to be fed within the magazine will automatically engage the supporting portions of the pendant or exhibited sign, to be actuated at the proper time for removing the exhibited sign.

A still further object oit' the present invention is the provision of a mechanism which automatically, during the elevation of a pendant sign from exhibiting position, will release a single sign from the magazine and permit the same to slide by gravity to exhibiting position.

`With the 'foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in- Specifcaton of Letters Patent.

Serial No. 713,086.

vention herein disclosed can be made within the scope oi' what is claimed without departing from the spirit of the invention.

In the drawings-Figure l is a side elevation of the exhibiting mechanism with the casing removed, the parts ol' the mechanism being .in the position assumed when exhibiting a sign, and just prior to the initial step in the elevation of the exhibited sign. Fig. 2 is a similar view with the sign elevating mechanism and releasing finger at their highest point and just prior to the releasing ol a succeeding sign ior exhibition. Fig. is a similar view with the elevating arms at iull length alter having released a sign and previous to releasing the retarding lingers controlled by the elevator, dotted lines illustrating the position ol the arms and sign during the elevation thereof and prior to the release of the sign. Fig. Ll is a similar view with the retarding fingers released and the sign entering the magazine, the elevating arms heilig moved downwardly to the next receiving position. Fig. 5 is a section through the machine, with the parts in the position they assume as shown in Fig. 3. Fig. (5 is a top plan view of the complete mechanism, with the iasing removed, the elevating arms being in the position as shown in Fig. 3. Figs. 7 and 8 illustrate the side and top view of the operation of the elevating arms when moving downwardly to receive the exhibited sign. Fig. 9 is a diagramn'iatii': view of the electrical circuit used to control the motor to operate the mechanism. Fig. 110 is a perspective view ol one ol the exhibits per se. Fig. 1l is a detached view of the clutch used to operatively connect the motor to the exhibiting mechanisn'i.

lle'lerring to the drawings, the numeral l desiguales the base ol the machine and 2 the verti lal standards, which support the top 3, thus providing a means whereby a casing (not shown) may encon'ipass the entire top and standards and conceal the mechanism from view.

Marin frm/zc mtl magos/inc.--Secured to the base are the two l'orward uprights Jr and elf, the two intermediate and longer uprights 3 and 5', and the rear supporting brace 5 to support at the proper incline, the two oppositely disposed plates (3 and (5 resiiectively. rlhe upper edges a of the plates 6 and G constitute a guide for the reduced ends ifi oi' the sign S, which when in niagazine position is disposed as shown in Fig. 1, at the forward ends of the plates 6 and 6.

Connected to the plates 6 and 6 and bridging the same near the forward ends and extending above the sign S within the magazine is a bridging plate 7, which carries the two rearwardly and upwardly extending curved sign guiding plates 8, whose free ends are supported by the transversely disposed bridging plates 9 whose terminals are connected to the outer faces of the respective plates 6 and 6 near the supporting standards 5 and 5. The extreme ends 10 of the guiding plates 8 are bent downwardly at a point intermediate of the length of the plates 6 and 6, the purpose of which will presently appear.

The forward upper edges of the plates 6 and 6 are shouldered as at 11 and thus provide an abutting means for the reduced ends S of the sign S to retain the forward sign in position in combination with the abutment 11 disposed at the forward edge of the base 1. By this means the signs S will all be disposed in parallel to each other and yet at an incline according to the inclination of the edge a of the plates 6 and 6 relatively to the base 1. The eXtreme forward ends 12 of the plates 6 and 6 respectively are projected into the cut-away portion 18 of the base, such cut-away portion forming the Outlet for the depending o-r pendant sign when in exhibiting position as clearly shown in Figs. 1 and 8.

Sign feeding mccham'sna-The sign feeding mechanism, whereby one sign at a time is fed from engagement with the projections 11 of the plates 6 and 6 and down over the inclined edges b of the extensions 12, consists of the two levers 15 and 15 which are pivoted as at 1li and 111 to the respective vertical supports 5 and 5. The freeends 16 and 16 of the respective levers are disposed toward the rear of the machine, to be actuated as will later appear. In the forward ends 17 and 17 of the levers 15 and 15, are pivoted the sign extracting pawls 18 and 18, which are guided in their up and down movement by means of the pins 19 carried by the vertical strips l and 4L of the supporting frame. rlhe curved ends 2O of the pawls 18 and 18 are disposed when raised to engage the under edge of the respective reduced portion S of the foremost sign S in the magazine, due to the depression of the free ends 16 and 16 of the levers 15 and 15, and thus elevate a single sign above the projections 11 and onto the inclined edges 2'), the retraction of the respective elevating pawls 18 and 18 releasing the lerfs 20 from the sign and permitting the sign to slide by gravity down over the inclined edges b and in front of the terminal 12 of the forward extensions 12 of the plates 6 and 6 respectively. ln order to return the respective arms 15 and 15 to their lowermost position, the spring 21 is connected to the base and to the free end 1T of each arm, and in order to hold the elevating pawls 18 and 18 in the posit-ion to engage the respective signs, the spring 22 is employed and is connected to its individual pawl and to one of the standards 5 or 5 of the frame, The pins 17a limit the downward movement of the arms 15 and 15.

Sign receiver and holden-The sign receiver and holder, as the pawls 18 and 18 are elevated to eject a sign at a time from the magazine is normally positioned, as shown in Fig. 2, so that as the reduced ends S of the sign slide over the inclined edges b, the sign will be moved from the position as shown in Fig. 2, to that shown in Fig. 8 without any perceptible rllhe mechanism for accomplishing this, consists of the two supporting brackets 23 and 23 which are carried by the base 1 and form a fulcrum for the two levers 24tand 24, each one of which is provided at its upstanding free end with the plates 25 and 25, respectively, to

fo-rm a counter balancing means when the cross piece 26 constituting the sign carrying means is relieved of the weight of the sign S as will present-ly appear. The cross piece is provided with a plurality of plates 27 whose inwardly projecting prongs or hooks 28 are curved, and ride upon the forward edge of the projections 12 of -the plates 6 and 6 and thus when the cross piece 26 is elevated to receive one of the signs, the same forms with the inclined edge b a continua tion thereof to permit of the easy removal of the sign from the inclined edges b into the receptacle formed by the respective prongs 28. In order to prevent any jar as the sign is delivered into the respective hooks 28, the cushioning spring 29, o-ne to each hook 28 and also connected to the cross piece 26, is disposed toward the free end 80 thereof in line with and between the body portion and the terminals of the respective hooks 28. By this means the lugs S will normally assume the position as shown in Fig. 8 with the said lugs S at the rear of the free ends 30 of the cushioning springs 1n order to prevent any undue swinging of the sign when in exhibiting position, the respective cushioning wires 80 are carried by the cross piece 26 and thus retain the pendant Vsign in a proper position and against swinging due to the delivery thereof within the elevating mechanism, or the jar of the vehicle carrying the exhibitor. In order to cushion the downward movement of the arms 211 and 241 after having received the sign, the buffers 81 are positioned upon the base, as clearly shown in Fig. 6.

Sign elevating meclzfmsm-ln order to remove the sign from the outer free ends of the arms 2-1 and 24 and return the pendant sign to the magazine after the proper exhibition thereof and to make ready for the reception of the next succeeding sign to be exhibited, the two journals 32 and 32 are carried by the base to the rear of and within the journals 23 and 23 and have disposed for rotation therein the transversely disposed shaft 33, which has keyed there upon the gear wheel 34, which is normally in engagement at all times with the teeth 35 of the rack bar 36. This rack bar 36 is pivotally connected, as at 37, to or near the lower free end of the main actuating lever 38. This actuating lever 38 is hingedly connected, as at 39, to a plate 40, said plate 40 being supported from the rear connecting bars (5"L of the plates 6 and G. Upon the inner face of the actuating lever 38 is the cam projection 41, while the lower free end is engaged by a spring 42, which normally tends to move the actuating' lever 38 toward the front of the machine or in the direction of the arrow as shown in Fig. 5. Two standards 43 and 43 are carried by the base 1 at the rear of the standards 32 and 32 and have journaled therein a shaft 44 which as shown in Fig. 5 carries an arm 45 with the anti-frictional roller 46 in the free end thereof. As this shaft 44 is rotated, as will later appear, the free end of the lever engages the actuating lever 38 and moves the same in opposition to the spring 42 so as to rotate through the gear 34, the shaft 33 as will later appear.

Carried upon the extreme ends of the shaft 44 outside of the journals 43 and 43, are the respective cams 47 and 47 which are disposed in operable relation to the free ends 16 and 1G of the sign projecting arms 15 and 15', the complete operation of which will be set forth later on.

Keyed upon the extreme end of the shaft 33 are the two arms 48 and 48, respectively, which are connected at their free ends by means of the cross piece 49, said cross piece 49 being so positioned as to describe an arc of a circle to abut the spring terminals 30 of the cushioning springs 29 carried by the cross piece 2G of the sign receiving and hold ing mechanism.

Connected to the extreme ends of the arms 48 and 48 are the downwardly extending strips 50 and 50, which carry the plates 51 and 51 respectively. Each one of these plates 51 or 51 is provided with a guiding strip, which is provided with the forward slightly curved edge 52, the receptacle portion and the releasing cleat 54. By this means when the arms 48--48 are moved downwardly from the position shown in Fig. 3 to that shown in Figs. 1 and 7, the sign being in the hooks 28, the two edges 52, of the plates 51 51', abut the inner' faces of the lugs S of the pendant sign, and move the sign against the tension of the springs 29 and toward the cross piece 26. As the top of the edges 52 pass below the lower edges of t-he lugs S, the springs 29 being released proppl the lugs S', and the sign so that the lugs S pass between the plates 51--51 and assume the position shown in Fig. 7 The receptacle portions and the cleats 54, provide a means for retaining the lugs S of the sign during its elevation from the position in Fie; 'l to the position shown in Figs. 2, 3 and o, at which latter position the sign has been released from the korf or cleat 54 and deposited upon the upper edges a of the plates and 6.

In order to guide the signs to permit them to fall upright upon the edges a of the plates (3 and 6 when the elevating mechanism is in the position, as shown in Figs. and 5, the plates 51 and 51 carried by the cross piece 49 are provided with the plates 55 having inturned ends 50 disposed to cooperate with the kerfs 54 and provide a space therebetween to permit of the lugs S in an upright position to slide therethrough to be depos-4 ited upon the upper edges a of the plates 6 and G.

As there is a possibility of the signs when being deposited upon the upper edge of the plate 6 having one end to travel faster than the other end and` thus tend to fall between the plates G, the retarding arms 58 and 58 are provided and are pivotally connected at 57km to the upper end of the plates (3 and 6 respectively. The outer free ends 59-59 of the retarding arms 58 58 are projected beyond the cross piece 6 and are disposed to be engaged by the adjacent edge of the cross piece 49 of the arms 4;8w48, simultaneously with the releasing of the sign from thc plates 51H51. This action elevates the hooked ends (StL-G0 of the respective retarding arms 58--58 above the edges a of the plates (3*0 respectively, so that the reduced ends or lugs S of the released sign S will assume the position, as shown in Figs. 3 and 5 and be retained by said hooks GOM-GO until the elevating arms 48-48 have again moved to release the free ends 59-59 of the arms 58--58. 'It will be noted that thc respective hooks (SO-(SO are positioned at a point just beyond the terminals of the depending ends 10 of the elevating guides 8, and are so close to the inner faces of the respective plates (i and G as to not interfere with the main pfnftion of the signs S, as the lower free end thereof is rc leased from the elevating guides 8 and falls between the respective plates and 6. This slight retardation in the travel on the inclined edges a. of the plates (3H-(V, prevents the sign from unduly swinging due to the freeing of the lower end thereof' from the inclined ends 10 of the elevating plates 8 and the position of the plates 51-5`l carried by the arms 48-48.

Motor (mtl control mechanism-The motor and control mechanism for the present apparatus is preferably actuated by electricity, although it is evident that the same may be a spring motor and in "fact any other means that will effectually operate the mechanism before described.

The gearing with the electric motor M depends entirely upon the speed of the motor, and therefore the detail structure. herein shown is provided more for illustration, but is one of the methods to be employed, and particularly where a high speed motor is used. may be employed, or that the speed of the motor may be reduced when found desirable by the placing of a resistance in the motor circuit. In the present instance, the i main actuating gear 61 is keyed upon the shaft 411- between the standards A13- 43' and is controlled through the electric motor M by means of the clutch C, as clearly shown in detail in Fig. 16. is shown the motor shaft M is reduced as at (a2 and has a gear 62 rotatably mounted upon the reduced portion and carrying a clutch finger 63 which is disposed in the path to be engaged by the clutch finger c, carried by the sleeve c slidably mounted upon the motor shaft M. The gear 62 meshes with a gear 64 mounted upon the short shaft GeV, the gear 64e also having a smaller gear which is in mesh at all times with the small gear 66, mounted upon the stub-shaft 67. The geai` 66 is in mesh with the gear 68 which carries a small gear 68, which is in mesh at all times with a larger or mainoperating gear 61. By this means it will be seen that when the clutch C is thrown in, that motion will be transmitted to the large gear 64 and the shaft Let through the medium of the train of gears connected to the shaft 62 and the other intermediate gearing of the shaft.

In order .to simultaneously control the actuation of the clutch C and also the electrical circuits controlling the motor M, the lever 69 of the clutch is properly mounted to the machine, a spring 70 being connected to the lever 69 to normally actuate the same to throw the clutch C out of engagement. This actuation of the clutch C is accomplished through the medium of the link 71 which is connected to the bell crank lever 72, said bell crank lever 72 being pivoted at 73 and having its free end 74C in a position to be engaged by the cone-shaped core 7 5 of the solenoid 76. The other free end of the bell crank lever 72 is kerfed as at 7 2 and is disposed to register normally with the notch d formed in the cam 61 carried upon the outer face of the operating gear 61. By this means when the solenoid 76 is energized, the bell crank lever is operated to release the kerf 72. from the notch d of the cam 61', throwing in the clutch C and at the same It is evident that a low speed motor time establishing an electrical circuit through the motor M as will presently appear. This circuit remains closed during one full rotation of the gear 61 or until the notch l is again in t-he position to-receive the kerf 7 2 of the bell crank lever 72, the spring 70 moving the parts so as to open the circuit to the motor M and throw out the clutch C. rlhe energization of the solenoid 76 is only of sufficient duration to close the circuit to themotor M and throw inthe clutch C, and to free the end carrying the kerf 72 Afrom the notch (Z of the cam 61, and would therefore, unless intercepted immediately return to the notch tl and the machine would fail to operate. To avoid its immediate return, the arm 200 is pivoted near the shaft 44- and carries the segmental plate 201, whose outer edge is beyond the edge of the cam 61, and the curve of which is concentric with the cam 61. rlhe spring 202 holds the arm 200 toward the front of the machine or in the direction of the rotation of the gear 61 and cam 61, and provides a resilientrswitch to be engaged by the kerf 7 2 of the lever 72 until the cam 61 has moved a distance greater than the notch CZ, at which time the kerf 7 2 is guided upon the cam 61 and is held in such position until the cam 61 has traveled one full revolution, at which time the kerf 7 2 having acted upon the segmental plate 201, to open the notch (Z, will be snapped into said notch Z to halt the motor. As above explained, when the kerf 72 is again drawn from the notch d, the spring 202 through the arm 200, draws the segment to its normal position, thus instantly locking the kerf 72 from returning to the notch (l.

Electrical control- As clearly shown in F ig. 9, the electrical control for actuating the solenoid 76 and the motor M is shown, the diagram being the complete circuits for energizing the solenoid 76 and actuating the motor M, the circuit being controlled through a car carried mechanism and means disposed in the path of the car. ln the diagram the contact 77 is carried by the inner free end of the bell crank lever 72 and has led thereaway from the conductor 7 6 to the motor M, while led away from the motor M is the conductor 76 which is connected tothe batteries B or any other source of electrical energy, and led away from the battery B at the opposite side to the conductor 79 is a conductor 80 provided with the stationary point 81, which is disposed in the path to be engaged by the contact 77, so that when the lever 72 is operated due to the solenoid 76, the circuit is closed to include the motor M and remains energized as long as the cam 61 retains the lever 72 in such closed position, that is one full revolution of the gear 61.

ln order to control the Asolenoid 76 automatically or manually as may be desired, a conductor 82 is led thereaway from and through a closing switch 83, which is main tained closed during the entire time that the exhibiting mechanism is in use. Led from this switch is a conductor Sit which is connected to the source ot' electrical energy lll, which has led thereaway from a conductor S5 to the automatic control switch Sli which is connected to the solenoid through the conductor S7.

In order to permit the actuation ot the indicator manually by the inotornian or conduetor, the two switches 89 and il() are employed and are bridged to the conductors 85 and SG through the conductors SS and lll, as clearly shown, the same providing a means whereby the indicator may he operated manually by either the coiuiluctor or the motorman, or may be operated automatically through the switch 8G, said switch being automatically controlled by a car car ried mechanism and a mechanism disposed in the path of the traveling car.

Operatioa-.mlrom the foregoing description, taken in connection with the drawings the operation ot the present invention is readily understood but briefly stated it is as Yfollows: Pre-supposing the parts to be in the position as shown in Fig. 1, with the sign pendant and in exhibiting position, with the elevating mechanism in engagement with the lugs S ot' the pendant sign S. the trolley earried mechanism is actuated to energize the solenoid 76, such energization aetuating the bell crank 72 to close the circuit to the motor M and at the same time throw in the clutch C. As before stated, this energization of the electromagnet is sufficiently long to cause the lever 72 to have its kerf 72 thrown from engagement with the notch d ot the cam 61', said cam 61 holding the lever in circuit closing position for one full revolution of the main gear (i1. The clutch C now being in and the motor actuated, the gear 61 will be rotated and consequently rotate the shaft all, the sign ejector actuating' cams L7-4:7 and the sign elevating actuating arm 45. The free end ot' the arm 45 being brought into engagement with the actuating lever 38 will now pull upon the rack bar 3G and rotate the shaft 33 through the medium of the gear 3ft and consequently start the elevation of the arms iS-4S and the cross bar L9 et the elevating mechanism. As the sign disposed between the plates 51--51 is removed trom the arms 28 of the sign holding arms 21 and 2li and assumes the position as shown in Fig. Q, the cams l7-47 are placed in engagement with the tree ends leale ot the ejector actuating levers l5- 15. This movement will raise the pawls 18-18 and consequently cause their ker'ts 20 to engage the reduced ends S ot' the lowermost sign Si in the magazine, elevating the same above and upon the incline Previn ous to this action, the weights 25 due to the release of the pendant sign trom the outer tree end ot the arms 2t-Qt has moved the receiving hooks QS to the position, as shown in Fig. 2, so that the extreme ends thereot will be disposed in continuity with the curved edges o, so that the released sign due llo the ejecting pawls Al 8-18 will be received in such hook :5S without any perceptible jar, said sign overcoming the weights 2 and causing the arms @PM2-t to assume the position as shown in VFig. P). By this means an exceedingly short interval between the release or removal ol a pendant sign and the reception ot the next sign will be the result. The continued action oft the lever 3 due to the arni 45, will cause the elevating arms #t8 t8 to move lrom the position as shown in Fig. 2, dragging the signs S over the guides 8 until the :tree edge thereoit' will ride drnvnwardly upon the inclined terminals l0 et said plates 8 and be caused to -lall downwardly between the plates G and (i. The con tinued movement ot the arms 11S-4S and the cross plate Mitl) toward the rear olf the machine, and just prior to the position as shown in Fig. 3, will present the lugs S in the plates 5in-51', so that the said lugs will be received in the kcrt' 54totI the plates 5].51 and as the cross piece ett) engages the free end 59 of the reta rding levers iS-58', the sign will be released through the spaces be tween the cleats 5ft and the extreme ends ot the arms where the, same will be permitted to tall and engage the upper edges (a ot' the respective plates (3 and thus permitting the main portion o't` the sign S to bridge the space between the plates (i and 6 and due to gravity slide downwardly to engage and be retarded iu its movement by the li'lted hooks GO and G0. The elevating arms 48u48 and the cross piece 41.9 are held in this position 'for an instant and until the lever 45 is moved upwardly about an angle ot 90, as shown in Fig. and until the roller lo becomes disengaged :from the cam 41 of the actuating lever 3S. At this moment the spring 12, which is normally exerts ing a tension in opposition to the lever 45 will move the rack bar 35 in an opposite direction, and thus rotate the shaft 33, which due to the spring l2 and the spring band connection 42', will impart a quick movenient to the arms 4S and the cross piece 49, which moving iu an opposite direction to that oit elevating the sign will assume the position, as shown in Figs. l. and 7 bringing the forward slightly curved edges 59 oit the carrier down past and below the bottom edge oi the sign lugs S, which owing to the action ot the springs Q0 are moved slightly back and thus place the cxtreme ends ot the lugs S ot the pendant sign S within the rcceptacle termed bv the inwardly bent edges 52 and 53 carried by the respective plants 51 and 5l of the extreme outer ende ot the elevating arms @i8 and d8. As the cross piece 49 is moved to release the free ends 59-59 of the retarding levers 58-58, the hooks 60-60 will be depressed below the edges t of the plates 6 and 6 and thus permit the pendant sign which has been momentarily halted in such position, to slide downwardly upon the edges a and resume its proper position within the magazine.

The clutch employed with the present invention has the knife-edge or pointed arms especially adapted for actuating a mechanism similar to the present one, and wherein neither part of the clutch is rotated and may be thrown together, the respective engaging members of the clutch being so constructed as to render the movement to and from each other exceedingly smooth,v so as not to jar the train of gears and the operating mechanism of the sign. lt is desirable that the bell crank lever 72', which operates the clutch, should have moved the clutch into engagement-'before the closure of the motor circ-uit, thus placing the clutch in engagement with the motor shaft at a standstill.

With a. mechanism, as herein set forth, it is evident that the same will be efficiently operated whether the car or vehicle is moving either slowly or rapidly, it simply being necessary for the electromagnet 76 to be energized to actuate the bell crank lever 72, to release the same from the notch cl' of the cam 61, such release closing the motor circuit and at the same time actuating the clutch and locking the clutch in engaged position so that the denergization of the electromagnet 7G will in no way aifect the operation of the motor, which is held energized until the main gear 6l has rotated one full revolution and a complete train of operations in the exhibiting mechanism has taken place. rIhe same may be said when the switch is controlled by the conductor or motorman, it simply being necessary for either the motorman or conductor to close and open the switch to energize the electromagnet 76. It' is also evident that with the mechanism herein set forth, that the pendantl sign when in exhibiting position, said sign being a double faced sign, is disposed below and exteriorly of the casing and preferably in the center of the car, so that the sign will be readily seen by the patrons and will never be obstructed from view by any portion of the casing or exhibiting mechamsm.

`While herein is described the invention in detail, and is illustratedv a combination embodying various features, which may at 'times be used to advantage, it is not the desire or intention of claimant to be limited to the particular arrangement shown, or to an arrangement embodying the various auxiliary features, except as particularly Vpointed out in the appended claims.
