Specification of Letters Patent.

Patented July 10, 1917.

Application filed August 1, 1916. Serial No. 112,520.

This invention relates to a device which 1 is adapted to be displayed in a car at a point plainly in view of the passengers for the purpose of announcing or exhibiting the names of stations or street crossings along an electric or steam railway as the car or train approaches the stations or crossings,

and also for exhibiting the names of business firms or advertising data.

The invention has for its general ob]ects to improve and simplify the construction and operation of apparatus of this character so as to be reliable and efiicient in use, comparatively simple and inexpensive to manufacture and keep in operative condition and have its various instrumentalities operative from a single pull cord or pushbutton within the control of the conductor or the person in charge of the car or train.

A more specific object of the invention is the provision of a plurality of. ribbons and cooperating spools so arranged that portions of the ribbons are displayed through. openings in the casing of the device for exhibiting street or station-names, firm names, advertising data, etc., the reels being mounted and operated in a novel manner so that they will move step by step by the operation of a single actuating means.

Another object of the invention is to provide a simple and effective reversing device for the rods to permit the ribbons to be driven in either direction.

Still another object of the invention is to so mount the reels of a name-bearing ribbon that they can be bodily reversed to display either side of the ribbon through the opening in the casing.

lVith such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts whichwill be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figs. 15 and 16 are detail sectional views respectively on the lines 15-15 and 16-16, Figs. 2 and 1.

The indicator is adapted to be removably mounted on a suitable bracket at the forward end of a car, and when the car reaches the end of a trip and is to return without the car being turned, the device is removed and placed at the other end of the car. A pull cord extends through the car and either end of the pull cord is adapted to be operatively connected to the device. If the device is to be electrically operated, a push-button will be arranged at each end of the car or at any other suitable point, and the device will have means for connection with the pushbutton circuit, as will be readily understood.

The indicating device comprises a casing A having openings 1 and 2. in its front for respectively displaying advertising data, names of business firms and the like, and street or station names, the openings being covered by glass 3 for protection.

Behind the opening 1 and within the easing is a flexible strip, ribbon or conveyer B which winds and unwinds 011 reels and G. The conveyor B has longitudinal slits 4' adjacent its side edges for receiving tongues 5 on the ends of advertising or dis 7 play cards 6, as shown in'Fig. 10. 'By this whenever desired.

means the advertising data can be changed .Adjacent the side edges of the conveyer B are apertures 7 for cooperating with stop or registering means which insures stoppage of the conveyer with an advertising card directly behind or in register with the opening 1 of the casing. The apertures 7 lie centrally of each advertising card 6.

Behind the lower opening 2 lies a flexible element or ribbon D which winds and unwinds on'reels E and E. The ribbon D bears the names of street crossings or stations, the space reserved for each name being indicated by the broken line rectangles 8 in Fig. 11. Along the edges of the ribbon are apertures 9 cooperating with stop or registering devices in the casing for insuring the proper register of the station or street names with the opening 2 in the casing. The ribbon D may have station or street names on both sides, but the names on'one side are reversely arranged with respect to the names on the other side. Mountedwithin the casing at the rear thereof is a horizontal main shaft 10 from which power is derived for actuating the ribbons B and D intermittently orstep by step. This shaft 10 is actuated electrically or mechanically. For the former purpose a solenoid 11 is arranged within the casing and the core 12 is connected by a rod 13 with the arm 14 of the bell-crank lever 15, such lever being fastened to the shaft 10 16 which is operatively connected with the ratchet devices for the ribbon feeding means; The solenoid operin one direction moves the same in the opposite direction. It will be understood that pushbuttons will be arranged at opposite ends of the car and I employed to connect the pushbutton circuit with the solenoid of the device when the latter is changed from one endof the car to the other. To mechani cally operate the shaft 10 the latter has one end extending out :of the casing, and fastened to this extending end is an arm 18 formed with a orotched extremity 19 into which is fitted a spool-like knob 20, as i The conductors pull rope 21 has one of these members '20 fastened to each end so that the indicating and V ratchet wheel opposite direction,

ranged that one tooth advertising device can be mounted at either end of the car, it being merely necessary to insert one member or the other in the crotch of the crank 18. The crotch has a spring catch 22 for holding the member 20 releasably in place.

The upper reels 0 and C are mounted on tubular shafts 23 and 24, respectively. These shafts are supported at one end in fixed bearings 25, as shown in Fig. 4:, and the opposite ends of the shafts are supported on bearing pins 26 which are carried by a door 27 at the side of the casing opposite from the bearings By opening the door the adjacent ends of the reels are left unsupported and the reels can be removed from the shafts. The reels C and C are provided with intermeshing gear wheels 28 and 29 so that the reels can be rotated, causing the ribbon or conveyer B to wind on one reel and unwind from the other. The gear 29 has a gear 30 connected therewith which meshes with a large gear 31. This gear wheel 31 is connected by a sleeve 32 with a 33 journaled on the shaft or stud 84; suitably mounted in the frame in the casing. Cooperating with the ratchet wheel is a pawl 35 fulcrumed at 36 on a rocker 37 loosely journaled on the shaft 34-, and this rocker is connected at 38 by a link 39 with the arm 16 of the bell-crank lever 15. A spring 4:0 interposed between the rockerand tail end of the pawl serves to engage the toothed end 41 of the pawl with the ratchet wheel 33. lVhen the pawl moves in a clockwise direction, Fig. 1, the toothed end slips idly over the ratchet wheel, but when the pawl moves with the rocker in the the pawl imparts a reels are actuated through the train of Only one reel is positively driven at a time, and for this purpose the reels are adapted to be clutched to the respective gear wheels 28 and 29 by the left heads h of the reels being frictionally held against the adjacent gear wheels In Fig. 4 it will be noted that the lower reel is frictionally clutched to the gear wheel 29, while the upper reel is free from its gear wheel 28. This relation is maintained while the ribbon moves intermittently in one direction throughout its length, and when the ribbon is to be reversed, the

lower reel will be unclutched from its gear 29 and the upper reel clutched to its gear 28. For maintaining this relation :1 toothed wheel 4.2 is journaled on a stud 43 carried by the door 27, as clearly shown in Figs. 2 and 4-, and this wheel has five teeth so ar- 43 engages the hub on the right end, Fig. 4-, of either reel. The hub of the lower reel C is shown engaged by the toothed wheel 42, and consequently this wheel maintains the lower reel clutched llv to its gear 29. VVhenthe wheel 42 is moved a distance equal to one tooth the said wheel will engage the upper reel and disengage the lower reel and thereby cause the advertising ribbon to travel in a reverse direction. This wheel 42 is moved only when the end of the ribbon is reached, and to effect this the wheel 42 has ten crown teeth 44 with which cooperates a reciprocatory push rod 45, Fig. 2, which has its upper end resting in a fork 46 of an oscillatory arm or lever 47, while the lower end of the push rod is connected at 48 with a crank arm 49 on the main shaft 10. A spring 50 is connected with the push rod 45 to assist in holding the latter down or seated in the part 46 of the lever 47. The rod 45 reciprocates with each step. by step movement of the ribbon, but the upper end of the push rod does not engage with any tooth 44 except when the lever 47 is held in lowered position, as when the end of the ribbon is reached, and consequently, when the next reciprocation of the rod 45 takes place it will engage a tooth 44 and move the wheel 42 one step. The manner in which the lever 47 will be held low ered will be presently described in connection with the registering mechanism for the ribbon B. wardly from the upper reel C over an idler roller 51, and from this roller the ribbon passes downwardly behind the upper opening 1 in the casing, under a lower idler roller 52, and thence to the reel G. Behind the portion of the ribbon B lyin between the guide rollers 51 and 52 is a loacking plate 53, and through this project stop pins 54 which are adapted to engage in the apertures 7 in the edge of the ribbon B, for the purpose of registering the advertising cards of the ribbon with the opening 1 of the casing. These pins 54 are carried on the front ends of the members 55, which are hingedly connected at 56 with arms 57 carried by a horizontal shaft 58. This shaft 58 is rocked with every movement of the ratchet device, so that the pins 54 will be removed to allow the ribbon to travel a step forward, and

when the end of the forward step. is reached, the stop' pins 54 will engage in the next apertures 7 and cause the ribbon B to stop at the proper point. The rock shaft 58is rocked during the forward or idle movement of the pawl 35, so that the pins 54 will be retracted from the rod before the'pawl actuates the ratchet wheel and causes the ribbon to move. To do this one of the arms 57 on the shaft 58 has an arm or member 59 extending downwardly toward the ratchet wheel, as shown in Figs. 1 and 5, and the lower end of this arm 59 lies in thepath of a cam 60 connected with or carried by the rocker 37, so that during the movement of the rockerin a clockwise direction, Fig. 5, the cam 60 will strike the arm 59 and move The ribbon B passes upthe arms 57 to the left, Fig. 5, so as to retract the stop pins 54.

During the first half of the movement of the rocker 37 no effect 18 produced except the increment of the ratchet pawl 35, and

and the pins 54 retracted, but at the begin ning of the second half of the return movement the cam moves from under the member 59, so that the stop pins 54 can moveforwardly and bear against the rear side of the ribbon B, and when the next open- 0 'ings 7 reach. the pins 54 the latter spring into the openings and stop the ribbon. This forward movement of the pins into the openings 7 causes a shoulder '61 on the member 59 to engage the tail end of the pawl to disengage the toothed end 41 from the ratchet wheel, so that the actuating means for the ribbon is stopped at the same time the pins 54 enter the openings 7 of the ribbon. The forward movement of the pincarrying members 55 is effected by a helical spring 62 coiled around the shaft 58 and fastened thereto at 63, Fig. 3, the other end 64 of the spring being fastened to the adjacent bearing 66 for the shaft 58.

1 At each end of the ribbon B there is an opening 7 only at one edge, and consequently one of the stop pinsj54 will bear against the rear side of the ribbon and will be prevented thereby from moving forwardly with the other pin 54. This restraining movement is made use of to hold the arm 47 lowered in order that the push rod 45 will move the reversing or switching wheel 42 one step forward to unclutch the clutched reel for the upper ribbon and clutch the unclutched reel to the driving means. The hub ('37 of the arm 47 is connected with the shaft 58 by a lost motion connection consisting of a slot 68 and pins 69. This lost motion connection allows the shaft 58 to rock under the tension of the spring 62 for engaging one stop pin 54 in the alining opening of the ribbon while the other stop pin bears against the back of the ribbon. The hub 67 is connected by a helical spring 70 with the shaft 58, so that normally the shaft 58 operates through the spring 70 to move forwardly the locking pin 54, which is connected with the hub 67 of the arm 47 In Fig. 8 the left arm 57 is connected with the shaft58 through the spring 70, and the right arm 57 is positively connected with the shaft 58, it being understood that the stop pin 54 con bearing nected with the left 211 11153 is the one that s held back by the unperforated end portions f the ribbon when the :ribbon is unwound, and, being thus held back the looking pin 54: causes the reels to be reversed, as heretofore explained.

Taking up the lower ribbon D, it will be noted that the ribbon passes from the upper reel forwardly to and in front of a support F in the form of a plate which lies behind the forward opening 2, and the ribbon passes baokwardly from under the support F to the lower reel E. The reels E and E are supported respectively on hollow shafts 71 and 72 which are carried at the right ends, Fi 3, on a hanger 73, and the opposite or le ends of the shafts, Fig. 8, are supported on bearing pins 74 which are disposed in sleeves 75. These sleeves are slidable in openings 76 in the upper and a hanger 73, and each sleeve 77 slidably en- 4 and 14. By can slide in the openings '76., and on the centering The extensions 77 extend comthis arrangement the sleeves .pins 75.

qpletely, through the hanger 7 and :are

adapted to be engaged by suitable means, whereby one sleeve is forced axially against the head 79 of the associated reel,- .so that such reel will have its opposite head 80 pressed into frictional engagement with a clutch disk 81. The clutch disks 81 for the upper and lower reels are connected respectively with gear wheels 82 and 83 gwhich mesh with an intermediate gear pawl 35.

. 85 is slidably a frame 87, which frame against either one of the the clutch sleeves 75. In I shows the. upper reel clutched to its gear wheel 84 that is driven by means of a ratchet device from the bell-crank lever 15. As shown in Figs. 2 and 4., a bowed spring mounted in a .guideway 86 of is connected by hinges 88 with one side of the casing so as to swing inwardly and outwardly through an opening 89, such opening being normally closedby a door 90. which is shown in section, Fig. 15, and broken away in Fig.

12. This spring slides vertically and has a knob 91 projecting outwardly through the door, so that the spring can be moved up or down. The upper and lower extremities of the spring .are adapted to bear Fig. 4 the spring 82, while the lower reel is free and disengaged from its gear 83. i

The lower ribbon is actuated from the shaft 10, which latter'has its arm 16 connected by a link 92 with-a rocker 93 journaled on a suitable bearing" member or shaft 94, and pivoted at 95 on this rocker .is a pawl 96 similar in arrangement and function to the The pawl cooperates with a arrest the ribbon when extensions 77 of. the nut though one hundred and tion, Fig. 1, it has no effect on the ratchet wheel but on the reverse movement the spring 98 of the pawl throws the tooth 99 thereof into engagement with the ratchet wheel so as to move the latter in an anticlockwise direction and thereby feed the lower ribbon D one step forward to thereby bring the next station or street name into view. The return movement of the rocker and pawl, together with the ratchet wheel, is effected by the spring 17, which is connected with :the bell-crank lever 15. The stopping of the ribbon at the proper time is veffected by stop pins 100 carried on and extending :rearwardly from the lower ends of depending arms 101 carried 'by a horizontal shaft .102. Fastened to this shaft 102 is an arm 103, Fig. 1, "which extends rearwardly and normally lies in the path of a cam 104 as- .nected with the arm 103 so as to cause the stop pins 100 to move rearwardly to engage in the openings of the ribbon D and thereby a name is in registry with the lower opening 2 of the casing. This lever 103 has a shoulder 106 which ongages the pawl at the time the stop pins enter the openings ofthe ribbon D, and consequently the pawl will be released from the ratchet wheel at the proper instant.

The lower reels and ribbon are so mounted that the position of the reels can be reversed, that is to say, the reel E can be moved downwardly and the lower reel E can be moved upwardly so as to bring the *rear side of the ribbon'to the front. This is especially useful where the car travels on a belt line and the ribbon will have the names of the streets or stations 011 both sides but in reverse order. For this purpose the hangers 73and 7 3 are mounted to rotate on their centers. The hanger 73 is operatively connected with a wing nut or equivalent device 106, Fig. 3, which is located outside the casing so that, by turning eighty degrees, the position of the reels E and IE will be reversed. Normally the hangers engage which have their lower extremitles 110 fastened to a horizontal shaft 111 journaled in bearings 112 in the bottom of the casing. One end of the shaft is provided with a wing nut or equivalent means 113, whereby the shaft can be turned to throw the levers 109 and the support F from the full to the dotted-line position, Fig. 2. Springpressed balls 11A in the bearings 112 engage the shaft 111 to yieldingly hold the levers 109 in their full-line position, Fig. 2. The support F is connected by pivots 11A to the levers 109, and a spring 115 connects the support F with each of the levers in such a manner as to cause the support to swing on its pivots as the lovers move backwardly.

This swinging movement of the support is limited by a pin 116, Fig. :2, on the support and engageable with the adjacent lever 10% Normally the support is disposed in a vertical plane, and when it moves rearwardly the spring 115 comes into play and tends to move the support F to lie more nearly in the plane of the forwardly-extending mem bers of the levers 109, so that the support when moving rearwardly will take up less space and pass between the reels E and E. hen the support is in its rearmost position the reels can be readily reversed without the support interfering.

Vhenever it is desired to remove the lower reels and ribbon the support F is moved to the rear partof the casing, as just explained, and the door 90 is opened so that the reels will be accessible and can be pulled longitudinally off their respective shafts.

e As the door 90 is opened the frame 87 is swung outwardly to thereby disengage the centering pins 74 and sleeve 75 from the reels. This leaves the reels free to be re moved from their shafts.

If it is desired to move the ribbon backwardly, the cord 21 is first pulled and held so as to disengage the stop pins 100 from the ribbon D, and then a knob or winged nut 115 is actuated to turn the intermediate gear 84, such knob 115 being disposed outside of the casing and connected with this gear through a shaft 116 which extends through a hollow shaft 9 1.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while we have described the principle of operation, together with the machine which we now consider to be the best embodiment thereof, we desire to have it understood that the machine shown is merely'illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
