INDICATOR AND ADVERTISING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 3'73.892, dated November 29, 1887.
Application tiled July 2l, 1884,
To @ZZ whom it may con/cern,.-
Be it known that I, MARSENA M. HooroN, a citizen of the United States, residing at Chicago, vin the county of Cook and State of Illi- 5 nois, have invented a new and useful Indicator and Means for Advertising; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawings, .forming part of the to same.
An object of this invention is to provide novel and improved means whereby a set vof cards can be practically, efficiently, and economically utilized as a means in cars for successively indicating at the proper times the stations or crossings to which the car or cars is or are approaching, and also for displaying to the passengers such advertisements as may be placed upon the cards alongside the names 2o or numbers serving to indicate the names or numbers of the streetcrossings or stations along the route. y
A further object is to provide a novel, simple, and efficient street-crossing or station indica'tor which can be conveniently iitted within a car without requiring any material alteratiouin the construction ofthe car as usually made, and which can be conveniently operated by theconductor from either end of 3c the car, so that, no matter at which end of the car the conductor is standing, he can operate the indicator and thereby notify the passengers of the crossing or station to which the car is approaching without calling out the same and without opening the car-door, whereby the objectionable feature of conductors or other attendants indistinctly calling out crossings or stations can be dispensed with and the constant opening of the 4car door in cold 4o weather avoided, in addition to which said feature the cards are rendered available for advertising purposes, so that at such time as any one or more advertisements may have been displayed for the time agreed upon, and it is desired tovreplace the same by new advertise ments, said card or cards can be replaced by new ones at a small expense and without removing the remaining cards or in any wise @hanging the lconstruction or arrangement of 5o the devices for manipulating the same.
A further object is to adapt said apparatus Serial No. 138,334. (No model.)
either for service in a street or railway car, or for use as a device for displaying photographs in hotels or other' public or private placesas,`for instance, photographs alternating with 5 5 business-cards can be successively displayed where the apparatus is to be used in public places, or the cards can be omitted where photographs alone are desirable.
To such ends my invention consists in the 6o matters hereinafter described, and particularly pointed out in the claims.
In an apparatus embodying the principles of myinvention a suitable casing or boxis pro,- vided with two card-receiving compartments, which are connected together by a single cardpassage arranged adjacent to the front of the box,whereat an opening is provided .through the front wall of one ofthe said compartments, in order to expose the top or front card of a pack of cards contained within said compartment. The top or front card of a pack of 'cards in either of the two compartments is normally held against the inner front wall of j the compartment and in line with the cardpassage by means of anysuitable construction of spring-follower or spring-backing arranged between the cards and the rear wall of the compartment, each compartment being provided with such an 'arrangement of springfollower for the purpose aforesaid.
The box or casing is provided at its front side with two independent card-shifting slides, each arranged to reciprocate over one of the two compartments. rlhese slidesare respectively arranged at opposite sides of but both in line with the card-passage, and each slide is arranged to slide back or away from the card-passage to Aan extent which will permit the top'card of apack within the compartment to which the slideis allotted to lie between the inner end of the slide and the card-passage, whereby when t-he slide is moved toward the latter it will push the card through the cardpassage and carry it into the next compartment. By such arrangement the two slides and the cardpassage are in one and the same plane at the front side of the box, and in order to permit a card whichis being pushed through' the card-passage by either' slide to overlap the follower in the next compartment adepressor movable transversely to the plane of the slides IOO and cardvpassage is arranged in front of or over each compartment at a point not far from the card-passage. The depressor in front of one card-compartment is momentarily operated from and by the slide which is being advanced over the other compartment, the action being to depress the follower until t-he advancing card has overlapped the same and to then retract or move outwardly out of the way of the advancing card.
Various mechanical contrivances can be devised for operating` the slides, and I do not confine myself to any special means for independently operating the card-shifting slides, as such will readily suggest themselves, aceording to the use to which the apparatus is to be put-as, for example, means suitable for operating the slides when the apparatus is hung up in a Streetcar will desirably differ in arrangement from means for operating the slides when the apparatus is placed ina railway-car, and, again, entirely different lneans may be preferable when the box with its slides and depressors is employed as a photograph showcase or album.
In the drawings, Figure l is a perspective view of one of the interior corners of a streetcar with my indicator and advertising device applied to one end ofthe car, with a cord shown passing from the apparatus through the said end portion of the car. In this gure the eardoperating mechanism is inclosed by a case secured to the wall of the car. Fig. 2 is a front view of the apparatus removed from the outer easing shown in the preceding figure and made of slightly-different proportions.

Fig. 4 shows on a larger scale one of the bell-clappers and devices included in its actuating mechanism. Fig. 5 represents one of the card-Shifters detached from its operating mechanism. Fig. (i represents a centrai longitudinal section through the apparatus Shown in Fig. 2, with the cards in pack form in one compartment and the top card in the act of passing to the adjoining compartment. Fig. 7 is a like view, but with a pack partially formed in each compartment and a card in the act of passing from one compartment to the other. Fig. Sis a transverse section taken through either one of the card-Shifters and its adjunets. Fig. 9 is a section taken transversely through one of the depressors and through the box at one side of its central partition. Fig. 10 is a face view of the apparatus made of somewhat different proportions Afrom that shown in Figs. 2 to 9, inclusive, and adapted for a case of the conformation shown in Fig. 1. This said Fig. l() also illustrates means by which the card-Shifters can be alternately operated or brought into action. Fig. l1 is a view similar to the preceding ligure with the means for operating the Shifters ap plied to operate the upper shifter, while in Fig. l0 said means are applied to actuate the lower one of the two card-Shifters. Fig. 12 is a side view of the same with the outer casing in vertical section, in which view the spring and supporting-rod therefor at this side of the apparatus are removed for convenience of illustration.
Referring by letter to the several figures of the drawings, in which like letters denote like parts, A indicates a box or casing, which can be made of any suitable dimensions and of wood or metal, or both, as maybe deemed most desirable. The box A is provided with two compartments, B, conveniently formed by arranging within the box a transverse parlition, A, situated at or abontthe middle of the box, as in Figs. (i, 7, and 9. Each compartment is adapted to contain a pack of cards of such size as may be found best suited for the hereiirdescribed purposes for which they are intended. An opening, A2, is formed through the front ofthe box, opposite one of thc cardholding compartments, so that the top card of a pack in such compartment s hall be exposed, in which way the top or front one of two or more cards opposite this opening can be seen and such matter as may be printed thereon readily read. These cardholding compartments are connected or eonnnunicate with each other through the medium of a passage, A3, formed near the front of the box and adapt ed to allow a carto be shifted from one compartment to the other. The simplest way of providing this passage is to leave a space between the front side of the box and the partition A. The object of this passage is toallow one card at a time to be shifted from either compartment to the other, and being situated at the front, as shown, the passage will only admit of the transfer or shifting of such card as may be at the top or front of a pack of cards in either compartment. The cards are lnaintained in pack form within either compartment and a pressure constantly exerted against the pack, so as to keep the top or front card thereof in line with the passage between the two compartments, by any suitable arrangement of spring-bachi ng or springbaeked follower, (such, for example, as may bc found in a variety of card-holders,) in which way the pack will be constantly pushed toward the front of the box with a yielding pressure, and hence the top card will always be maintained in position to be shifted from one compartment to the other. It will also be seen that this spring backing or follower in a compartment accommodates itself to the size of pack, being pushed back as the pack increases in size and moving forward as the size of the pack is diminished.
In the present illustration the spring backA ing or follower consists of a plate, C, between which and the back of the box are arranged springs C', tending to force the plate toward the front of the box.
It will be evident that various forms of springs for spring-backing the pack can be employed, the springs herein shown,which are IOO ISO
common `in apparatus for holding cards, serv- These Shifters or card shifting slides are eachA formed of a plate arranged to work in a plane parallel with the front of the box, and preferably made somewhat wider than the card to be shifted.
A card-shifter is provided for each compartment, and these card shifters are guided by slots or ways A, formed longitudinally through the sides of the box, near the front of the same.
Referring to Fig. 5, it will be seen that the card-shifter has at one end two corner projections, D, giving the effect of-a wide notch or recess formed in the plate between its two front corners. The space between these two corner projections is substantially equal tothe width of a card, so that when the, card shifter is movedforward to engage and shift a card from one compartment to the other the card, being at one-end engaged by the shifter between the corner projections ot' the latter, will, during the forward movement thereof, be steadied against any side movement, and hence will be prevented from shifting sidewise into either guideway A4. l
Each 'card-shifter is provided with a handle, or with some suitableappendage by which it can be conveniently connected with means for operating the same, which said means can consist of cords or levers, as desired.
As herein shown, a narrow plate or crossbar, D, arranged across the front of the box, is secured to each card-shifter, oner of said cross-.bars being provided foreach card-shifter and furnished with a knob, A, or with any device with which a'cord or hooks on cords can be conveniently connected. Each crossbar D2 is arranged to slide over the front of the box, and is bent back at its ends, extending beyond the sides of the box, so as to bring its said ends in position to be secured by screws D3 or other suitable means to lateral wings or extensions d of the plate forming the cardshifter, these said lateral or side edge extensions of the plate being extended out through the ways A4 at the sides of the box. This arrangement will be best understood by referring to Fig. 8, illustrating the card-shifting mechanism, embracing a plate arranged to work through the slots A4 and a cross-bar, D2, attached at its ends to the extensions d, formed at the rear corners of theplate.
Each card-shifter, when moved forward, is moved against a yielding spring resistance,
which, the moment the shifter is released, serves to throw the same back to its normal position, in which way the card-Shifters are both normally maintained in such position that when moved forward therefrom the advancing shifter will engage the top card of a pack in the nearest compartment. Said spring resistance is effectively provided by means of long spring-coils E. loosely arranged on stationary guide-rods F, which are supported at the sides of the box.
As a means for steadying the card-Shifters, and also for providing the same with abutments or shoulders for confining the springs on the rods and for acting against the ends of the springs, so as to compress the latter when either card -shifter is moved forward, each card-shifter is connected with a pair ofsleeves, D, arranged to slide on rods F, whereby the ends of the springs on said rods shall abut against the sliding abutments or sleeves D4. As herein shown, the lateral wingsor extensions d of the card-Shifters are secured by the screws D3 to plates d', formed with or rigidly secured to the sleeves Di, as best illustrated in Fig. 8, and the rods F, arranged parallel with 4the sides of the box, are secured at their ends to braeketeplates A, projecting from the corners of the box, as in Figs. 2, l0, and 1l. A single spring-coil is preferably arranged on each rod and between each opposing pair of sleeves fitted to slide on the rod, it being seen that by thus employing a long springcoil the same will not be compressed or compacted to an objectionable extent when either cardshifter is moved forward, since in along coil the accumulation willbe more gradual and less rapid than in a short spring-coil. The coil form ofV spring is herein employed as occupying but little space, and in other respects being more serviceable than any arrangement of bow or analogously shaped springs.
Assuming the cards to be all in pack form iu one compartment, as in Fig. 6, it will be seen that the front face of the front or top card of the pack will be exposed through opening A`l in the front of the box. This front card will be in the same plane as that occupied by the card-Shifters and the passage between the two compartments, and hence lif the shifter back of said card is moved forward it will engage the top card and push the same forward through passage A3 between the two compartments; but as the follower in the unoccupied compartment or any card upon the said follower will be normally held against the inner side of the front of the box, and hence in the way ofthe card to be advanced, it becomes necessary to depress or push inwardly the follower to such extent as shall leave room between the follower or any cards thereon and the front of the box for the advancing card. To such end I provide an automatically-operated depresso'r, which, during the advance of a card-shifter over one compartment, shall for a proper length of time push back slightly the IOO IIO
follower in the next compartment, and thereby make room in front of said follower or any card or cards thereon for the advancing card.
Over or in front of each compartment, and at points adjacent to and at opposite sides of the passage A3 between the compartments, is a depressor, G, arranged to work through a slot or opening formed transversely through the front of the box, one of said depressors being provided for each compartment. These depressors normally stand out from the front of the box, so as to allow the front card of a pack in either compartment to lie against the inner side of the front of the box, so that said card shall be in the plane iu which the shifters and the passage between the compartments are situated. While, however, a card is being pushed forward from one compartment to the other, asin Fig. 6, the depressor in front of the compartment into which said card is being pushed will be pushed inwardly, so as to depress or push inwardly the follower in said compartment to an extent which will allow the advancing card to lap over or pass in front of the edge of either the said follower or card thereon nearest the passage, in which way the advancing card can wedge in between the follower or cards thereon andthe front side of the box. As soon, however, as the advancing card has been brought into position lapping over the follower, as in Fig. 6, the depressor will be moved outwardly, and hence out of the way of the advancing card, so as to allow the latter to be still farther advanced, as in Fig. 7, in which a card shifter is shown in position to nearly bring the advancing card in position within a compartment into which the card is to be shifted. It is understood that the cardshifter is advanced sufficiently to push the advancing card entirely through passage A and to leave the card over the follower in the compartment in which a new pack is being formed. The operation of each one of these depressors is the same, one being brought into action during the forward movementof each card-shifter, so that the cards from a pack in either compartment can be successively shifted there from to form a pack in the opposite compartment. It will be observed that as soon as the depressor moves outwardly and releases a follower underit the advancing card between the follower and the frontof the box will keep the follower back as it is farther advanced, so that the depressor is only necessary for allowing the advancing cards to lap over the follower or any card or cards thereon, after which the advancing cards will successively push back the follower and cause the latter to yield to the gradually-incrcasing pack.
The depressors could consist of pins passing through holes in the front ofthe box and secured to cross bars outside of the latter; but preferably' each depressor consists of a comparatively narrow plate. g, arranged to work through a slot, g', formed transversely through the front of the box or case, as in Fig. 9. Each depressor is formed with or secured to a vibratory yoke, the sides or legs G' of which are pivotally supported at the sides of the box. These yoke-frames are bent so as to straddle the box, and one yoke is widened at its middle, so as to lie outside ofthe remaining yoke. Under such arrangement the middle portion of each yoke, which is constructed to provide a depressor, crosses the front ofthe box, and is then bent down at the sides of the latter to a short extent, after which the yoke runs outwardly or toward au end of the box, so as to form the legs G', which are parallel with the sides of the box and pivoted thereto. Each one of these legs has a cam, G2, (best shown in Fig. 3,) which said cams are formed at or ucar the outer ends of the legs of the yoke.
rlhe depressors G are normally held in their forward position, as in Fie. 7, by means of one or more springs, H, arranged on the front ot' the box or otherwise disposed so as to act upon the yoke-frames. These springs also serve to maintain the yokes in such position as to bring their cams or projections in the path ot' projections carried by the card-Shifters, so that when a card-shifter is moved forward it will engage the cams on one of the yokes and operate the yoke in order to move the depressor thereon inwardly. Said projections carried by the card-Shifters are conveniently formed ol' pins D5, projecting from the sleeves D'i toward the sides ofthe box. In this way, when a cardshifter is moved forward over one compartment, so as to advance the top card from a pack in said compartn'tent, the pair of pins D5, carried bysaid'advancingcard-shifter, will, during the first part of its forward movement, strike against the cams belonging to a yoke carrying that depressor which is over the compartment into which the card is to be shifted. As the pins strike and ride along these cams,the said yoke will be tilted so as to throw its depressor back into the box, in order to push back or inwardly the follower under such depressor, and as long as the pins are in engagement with these cams the yoke and the depressor thereon will be maintained in such position.
Fig. 6 illustrates a yoke maintained in such position as to bring the depressor against a follower and to such extent in the box as to hold the follower back in order to allow room for an advancing card. The depressor is kept in such position until the advancing card overlaps the follower, as shownin Fig.6. afterwhich the pins ofthe advancing card-shifter clear the cams and allow the springs to throw the depressor outwardly and out ofthe way ofthe advancing card, as in Fig. 7. By such arrangement a depressor is operated only during` a portion of the advance movement ot' a cardshifter, and the mechanism is so timed that the depressors shall not interrupt the forward movement of a card from either compartment.
In order to give notice to the passengers in a car that a card has been shifted, so as to call their attention to the name of the crossing to which the car is approaching, and also such ICO IIC
IIS
advertisement as may be placed on thecard, a bell or bells will be arranged in such way that when a card is or has been shifted abell shall be rung. As a convenient arrangement 'of bells and means for sounding the same at the proper moments, I provideupon one ofthe sides r is provided for each bell, each consist of an extension of a coiled spring, L', said extension being atit-s free end provided with a button for striking the bell. Referring more particularly to Figs. 3 and 4. each spring L is arranged about a stud, M, secured on the box. 4Each of said studs has a shoulder, m, located ,Y above said spring, and upon said shoulder is .endsof the clappers off from the bells.
arranged an oscillating plate d'r hub, N, provided with a stud or finger, n, normally kept in the path of the teeth on an arm, K, of the nearest shifter by means of a spring, -N, attached to the stud M and to the hub N. Each `hub N is also provided on its under side with` a pin, N2, and below said hub is arranged a stop, N, secured to the box.
The arrangement and operation of these.
parts are as follows: The springs Nl normally maintain the teeth or fingers n, on the hubs in the path of the teeth on arms K, carried with the card-shifters, and when the clappers are at a state of rest the stops N3 keep the striking The tooth of an advancing arm, K, engages the finger n of the nearest oscillatory hub and turns the latter so that the pin or finger N2 on said hub shall act against the spring-arm of the c lapper and swing the same away from the bell, thereby winding up the spring of the clapper, and also winding up the spring which controls the hub. As soon as the hub is released by reason of a further advance of arm K, the hub will-be instantly swung back by its spring, and
hence the clapper will be free to be swung back and sound the bell by reason of the unwinding action of its spring as well as by its individual spring action.
Obviously a variety of ways will suggest themselves in which a bell could be sounded at each transfer of a card from one compartment to the other, and hence I do not limit myself to the precise mechanism, sincein this part of my invention the prominent feature is a bell and means by which at each transfer of a card the bell is rung or sounded.
The box can be made, as in Fig. 2, with its greatest length coincident with the line of travel of the cards; but in many instances, ow-
ing to the space available for the apparatus, it is preferable to make the box wider and of a decreased length, as in Figs. 10, 11, and 12. A box of these dimensions will require or can, if desired, be inclosed by a case, P, subst-antially of the shape shown in Fig. 1, although of course the case can be made to suit a box of the form shown in some of the remaining figures where a box of such character is 'employed. W'here the box is thus inclosed in a case P, the latter will have an opening coinciding with the opening in the front ofthe box, and said case will also have any suitable arrangement of door or hinged side or sides, so as to allow access to the box for the purpose of putting in or taking out cards from the latter. The box .will also be provided with one or more doors or lids--sucl1, for example, as a sliding lid, Q, Fig. 3, which lid,however, can be hinged when found more. convenient.
This apparatus is especially applicable for use in street-cars, and can be either permanently secured in the car at one end thereof or can be temporarily hung up in the car and secured by buttons or the like, so that at the end of each trip the box can be moved by the conductor from one to the other end of the car.
A variety of means can be adapted for operating the Shifters from one or both ends ofthe car; and while the shifters could be operated `by slides, levers, or other analogous mechanisms, I have herein illustrated a cord as the operating medium, since the same can be conveniently run from the apparatus through the end of the car and terminate outside the latter in a weighted button, which shall be within convenient reach of `a conductor standing on either end platform of the car. The cord or cords can pass over pulleys arranged in or on the car-walls, and as soon as the car has passed one crossing a pull on the cord will operate such one of the shifters as the cord may be connected with, and thereby expose a card indicating the next crossing to which the car is approaching. These operations can be repeated until the end of the trip,
-at which time the cards from a pack in one compartment will have been transferred to and collected in pack form in the remaining compartment. On the return-trip no handling of the cards will be necessary, since by changing the connection of the cord with the shifting device the cards canV in the same way as before be successively shifted back into the first compartment, in which they will collect in regular order and in pack form ready for the next trip. As theorder of the' cards is thus preserved with relation to the required successive display of the cards, it will not be necessary to open the 4bx except for the pur! pose of replacing cards by others containingnew advertisements, or in the first instance introducing the pack.
A convenient way of operating the shifters where the apparatus is to be hung up in a street-car is shown in Figs. 10, 11, and 12, in which S denotes the main operating cord, which can be run 'either waylfrom the box, as in full or dotted lines, Fig. 12. rIhe cord passes over any suitable arrangement of pulley or pulleys and at one end connects with a cross- IOO IZO
bar, T, arranged to slide along guide-rods U, which stand out from the front of the box and are secured at their inwardly-bent ends to the latter. The sliding cross-bar T is guided on these rods by eyes t or the like on the bar encircling the guide-rods, one of which said eyes is shown in Fig. l2. The guide-rods should each have a stop, t', located at or about the bend at its lowest end, so as to prevent thc cross-bar T from slipping over said bend when the cord is slaekened up. Cords XV are attached to the cross bar T, near the ends of the bar, and at their free ends each provided with a hook. These cords XV pass over or around pulleys w, situated at or near the middle ofthe box,on the front thereof, and these cords are attached by their hooks to such shifter as is to be operated, for which purpose the bar D2 of each shifter can be provided with a pair of eyes or staples,with which the hooks can be readily connected. Thus in Fig. 10 the cords W are shown attached to the eross-bar D2 of the lower card-shifter, and hence by drawing on cord S the said shifter will be moved up or forward, and as soon as said cord is released the springs E will force the shifter to its original back position. This attachment of cords is also illustrated in dotted lines, Fig. 12.
In Figs. 1l and l2 the cords W (shown in full lines) pass around pulleys w, and are attached to the cross-bar Dof the upper shifter, so that by drawing on cord S this upper shifter will be operated. The pulleys w will each be arranged in any suitable block, strap, or yoke for preventing the cord from slipping off the pulley, in which case the block or strap can be formed in any way convenient for permitting the cord to be removed from the pulley or trained over the same, as occasion may require. Obviously, however, numerous ways can be provided for operating the shifters, and hence I do not limit myself to any special means. Thus this apparatus can be employed to advantage in a railwaycar for indicating stations, in which case, in place of advertisements, distances between stations might be preferable. The apparatus could be set or hung up at one end of the ear and operated by a brakeman, who could, in lieu of calling out stations, move the shifters through the medium of any suitable connection passing through a slot in the box and case. The gong or bell would in this instance call the attention of the passengers to the card thus exposed.
This apparatus could also be employed in any other connection where cards are to be used in the manner hereinbefore describedas, for example, the apparatus inclosed by an appropriate casing may be employed for displaying advertisements in hotels and other public places, in which case the cards may be alternately provided with photographs and ad vertisemcnts, and the use of cords dispensed with, it being obvious that means for operating the apparatus for such purpose could be provided without the exercise of inventionas, for example, a knob extending from the slide through a slot in the casing.
