CHANGEABLE EXHIBITOR FOR CARS.

Application filed March 18, 1922. Serial No. 544,879.

T 0 all whom it may concern.

Be it known that T, DIRK A. KLEIMAN, a subject of the Queen of Holland, residing at Ogden, in the county of Weber and State of Utah, have invented certain new and useful Improvements in a Changeable Exhibitor for Cars; 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.

This invention relates to a changeable exhibitor for railway cars, particularly of the urban and inter-urban type.

One object is to provide an apparatus of this kind which is controlled by a novel means from an obstacle on a trolley wire, the trackway or otherwise disposed in the path of travel.

Another object is" to provide such an apparatus having a novel escapement means operable by mechanism cooperating with obstacles in the'path of travel.

Another object is to provide a springactuated exhibitor having a motor operable to wind the spring, and a switch in the motor circuit controlled by operation of the apparatus.

It is further aimed to provide a novel means for paying out and rewinding a flexible exhibitor member or tape.

The invention aims to provide an exhibitor of the general construction and having the features and details hereinafter described with reference'to accompanying drawings illustrating one practical embodiment. Additional objects and advantages will become apparent from a consideration of said description and drawings.

Figure 15 is a fragmentary View in rear elevation of a modified form of escapement operating means, and

Figure 16 is a side elevation of said means of Figure 15.

Like reference characters designate like or similar parts throughout the views of the drawings.

The improvements are shown as associated with a street car at A. As the invention is capable of application to cars generally, such illustration is to be taken as conventional. The trolley or overhead feed wire of the car A is shown at B as engaged by the wheel C carried by trolley pole D. One of the usual transverse supporting wires for the wire B is shown at E.

An' exhibitor per se is illustrated and may be mounted at any suitable location within the car A as at the front or rear thereof in a position for view by all pas sengers. The exhibitor may have a casing in superposed sections 10 and 11 and within the section 10 aplurality of spools or drums 12 are journaled'to turn on vertical axes. Said spools 12 are preferably removably slecured in place in any suitable manner. To this end and as shown in Figure 14, plates 13 may be fastened to the bottom wall of section 10 and of such size as to form end flanges or disks for the drums 12, equivalent to the end flanges or'disks 14 thereof.

and have stub shafts 18 to mount the same which are journaled in a supporting wall 19 of said sections. Coupling disks or plates 20 are provided on the stub shaft 18 below support 19' and provided therein are conical sockets 21 to be engagcdliy a latch 22, having a correspondingly shaped conical; socket, and which latches are slidably mounted in recesses 23 of the cores of the spools 12 and urged outwardly by expansive coil springs 24 disposed therein. Slight movement of the spools 12 intermediate the plates 13 and. 20 is permissible to permit attachment and detachment of the stud 15 with the socket 16. Any suitable means may be provided to couple the spools 12 tothe plates 20. for unitary movement and tothis end, a: pin 25 may extend from. each plate 20 and enter radial slots 26 inthe flanges 14. It will thus be realized that the drums12 may be readily attachedand detached from the plates 20 and13.

elongated tape or ribbon 27 is provided which may be. divided into panels 28 containing eithibition matter, for instance atit-he top, thereof a name of the street or avenue or other-location forming the next stop and below which suitable advertising matter may, if desired be delineated. This tape has one end secured removably or otherwise to each of said spools 12. To the left, at thev front, a panel may be provided at 29 and have delineated thereon Next stop to form a key cooperating with the stop indication at the top of the panels 28. In actual use, the tape 27 will contain panels 28 for each block along its route so that the device will serve sufficiently as a street'indicator as well as an effective advertisement I Attention is called to the fact that the ad vertisement cooperates with the street indication, inasmuch as it relates to a business or profession adjacent the particular stop indicated on the panel 16. The tape 27 is adapted totravel across and for exposure at an exhibiting opening 30 in the section 10.

In order to properly guide the tape 27, suitable idler rollers may be provided within section 10 as at 3-1. In order to connect the spools 12 and'ta pe for removal from thecasing, the front" wall and end walls thereof may be removable or hinged as is obvious.

The tape is adapted to be driven positively and by any. suitable means. To this end, a spring motor may be employed utilining the shaft 33 to which one'end of a clock spring 34'is fastenedand which spring is located within a suitable casing 35 and which has its other end secured thereto as at 36. Casing 35 has a sleeve 37 in which the shaft 33 is journaled and which sleevein turn is journaled in the support 19. Formed integrally with or otherwise on-the sleeve 37 is a bevel gear wheel 38.

In mesh with the gear wheels 17, are bevel gear wheels 39 keyed to suitable shafts 40, ournaled in hearings 41 rising from the supporting wall 19. The inner portions of the shafts 40 are reduced as at 41 and keyed or splined thereto and ,slidable on the portions 41 are bevel gear wheelsp42. The wheels 42 are adapted to mesh one at a time and selectively with the gear wheel 3 r-iny'suita-ble means maybe provided to accomplish the shlftmg of the gear 42.

F or instance a yoke'isprovided at 43 having forks 44 engaging the gears 42 in such manner as not to. interfere with. rotation thereof. Yoke 43 is part of a lever 45 which may be journaled to swing horizontally-as from a shaft 46 and which may have a manipulating-handle at- 47. T he construction described forms a means whereby the motor 34 may wind the tape 27 for forward or reverse movement-towards the'opening The casing lOniay have anopening at 48 to permit insertion of the handof the operator to grasp the handle 47.

A main shaft 49 is journaled in "the upper and lower walls ofthe section 11 and extends into the; casing '10. Shaft 49' is adapted to be driven in the same direction as the 318.1% 33 and is in alinement withthe latter. Shaft 33 practically forms an extension of said shaft 49. Secured to the shaft 49 is one end of a clock spring 50 whose other end as at 51 is secured to the section 11. .Journaled on'the shaft 49 is a worm wheel 52 in mesh with which. is a worm 53 on ashaft 54 adapted to be-driven from motor 55, preferably of the electric type, in order to simultaneously drive the shafts 49 and .33 and thus simultaneously rewind spring meters 34 and 50. Worm wheel.52 has an inner gear rack 56 with which a pinion or gear wheel'57 meshes and which also meshes with the gear wheel 58 keyed to the shaft 49. Loose on the shaft 49 below gear wheels 57 and 58 is a large gear wheel 59-to which a stud or shaft 60 is rigidly fastened and on which gear wheel 57 is journaled. Below gear wheel. 59, a ratchet whee-l. 61 is fast on shaft. 49 and cooperating therewith is a spring pressed pawl 62 journaled on the stud (it). When the spring 50 unwinds, its motion is transmitted through the gear wheel from shaft 49 to gear wheel 57 and thence to gear wheel. 59. When the spring is wound. shaft 49 is turned throught-he turning of the worm 53, worm wheel 52, gear wheel. 57 and gear wheel 58, the pawl 62 permittingfa slip con nection of the wheel. 59 relatively to-shaft 49.

Shafts 33 and 49 are. not positively connected as a single shaft since at times they are required to move independently. To this end, the shaft 49 may have an exten sion 62 journaled in a socket 63 in the shaft 33. To this end, a pawl 64 is pivoted at 65 to the shaft 49. This pawl cooperates with teeth of a ratchet at 66. The ratchet 66 is positively moved by the pawl 64 when shaft 49 is turned to wind the spring. When shaft 49 turns in an unwinding direction, it moves independently of and relatively to shaft 33 during which action the pawl 64 freely slips over the teeth of ratchet 66. In order to prevent reverse rotation of the shaft 33, a pivoted pawl 67 is provided within the casing and engages other ratchet teeth of the ratchet 66 as at 68:

Through expended motion from spring 50, shaft 49, through the medium of gear wheel 59 and a gear wheel 69 keyed on the shaft 46 within the section 11, shaft 46 is turned. Keyed on shaft 46 is a gear wheel at '70. Journaled on a vertical axis within the section 10 is a shaft 71 which may carr one or more feed rollers 7 2 provided witi projections 73 adapted to enter projections 7 4 provided along the edges of the tape 27. Shaft 71 is adapted to be driven. in either direction from the gear 70 in order to turn the disk 72 and move the tape 27 through positive engagement of the teeth 73 in the openings 74. Thus the shaft 71 may have gear wheel thereon as at 75 above the supporting plate or wall 19.

To provide for reverse rotation of the shaft 71, a lever has a plurality of gear wheels 76 and 77 journaled thereon as at 78 and79. It will be seen that one of the gear wheels 76 or 77 is in engagement with the gear wheels 70 and. 75, and the other gear wheel is disengaged there-from. Such engagement will drive the shaft 71 in one direction. When the lever 45 is shifted, the other gear wheel 76 or 77 will mesh with i the gear wheels 70 and 75, thus driving the shaft 71- in the opposite direction.

A suitable escapement mechanism is associated with the parts described and to this end a shaft 80 is journaled as in bear- 81 within casing section 11. A gear .cel is keyed on said shaft 80 and ice with a gear wheel 83 keyed .d shaft 46. At 84, a. ratchet wheel en shaft 80 with which a de cooperates. Detent 85 is journaled t and has a lug 86 adapted to the teeth of the ratchet wheel 84. ted with the detent or arm 85 is a i: link 87 pivoted at 88 within casection 11. Detent 85 has a hook end 89 :{e overthe detent 85 when in en ent with the ratchet 84. A spring 90 the arm 87 into position engaging the 86. 'Detentarr'n 85 rests on a cam 91 keyed to shaft 80 so that Said cam will prevent too rapid return of arm 85 to normal position, thus controlling the period of escapement. A spring is provided at 92 to normally urge the arm 85 into engagement with the cam 91. Adjacent the cam 91, a gear wheel 93 is keyed to the shaft 80 which meshes with a gear wheel 94 keyed to shaft 46.

Secured to the detent is a wire or cable 95 which is guided on the car in any suitable manner as by one or more pulleys 96 and which passes exteriorly of the car and is secured to a lever 97 pivoted at 98 on the trolley pole D. A spring 99 is connected to the pole and to the lever 97 to retain said lever in a normal position against a stop 100.

Along the route traversed by the car A at each street or stop, a suitable abutment is provided to tilt the lever rearwardly which thereby draws the cable 95, elevating detent 85 to release the escapement. From the wire E may be supported, one at each side street or intersection between a main street, an abutment plate 101, disposed in the path of movement of the lever 97.

A suitable switch for motor is provided. This motor is shown in an electric circuit in Figure 13.- The source of current uti lized is shown at 102 having a conductor 103 leading to the motor and a conductor 104 leading to a contact 105. A conductor 106 leads from the motor to a contact 107. The circuit through the motor 55 will be closed upon engagement of contacts 105' and 107. As to theswitch proper, contact 107 may be stationary and arranged in suitable insulated relation on the top of section-11. Contact 105 is also disposed on and insulated from the top of the casing 11, being pivoted as at 108 to swing into engagement with contact 107. Contact 105 'is normally urged into a disengaged position against a stop 109 by a contractile spring 110. The switch is adapted to be closed at suitable intervals and to this end a gear wheel may be provided at 111, journaled on a bolt or stub shaft 112 to the top of section 11. Gear wheel 111 is driven by a gear wheel 113 meshing therewith and keyed to the shaft An abutn'ient 114, preferably of insulating material, is disposed on the gear wheel 111 so that as the gear wheel 111 turns, abutment 114 will strike the contact 105 and depress or swing it into contact with the contact 107. After the abutment 114 passes over contact 105, its spring 110 restores it to normal or open circuit position.

in practice, the motor 50, through its shaft 54 and gearing drives the gear 69 and shaft 46 and gear wheel 70. The latter. through the medium of the selected gear 76 or 77 drives gear wheel 75 which drives shaft 71 causing the disk 72 to cause travel of the tape 27 in the appropriate direction. The

motor 34' atthe same time expends its energy so as to wind the tape about one of the spools 12 to the same extent that it is unwound or unwrapped from the other spool, thus maintaining it in a taut condition across the opening 30. The winding action of the spring 345 is of course limited I to the amount of tape fed by disk 72 under control of their operating gearing and motor 50. At the desired time, the tape is adapted to be moved in the manner stated but normally it is stationary. WVhen it is desired to operate, cable 95 is drawn through engagement of lever 97 with the abutment 101 thus elevating the detent 85 and releasing'the escapement mechanism, permitting the parts to operate until the cam 91 moves from the position of Figure 12 to the positionof Figure 11, where the parts are again locked against movement by engagement of arm 86 with ratchet 8-1. As the parts operate, the contacts 105 and 107 are appropriately engaged at desired times to actuate motor 55'to rewind the shafts 49 and 33 through the medium of the worm 53, worm wheel 52 and appropriate gearing, pawl 64 and ratchet 66. It

i is to be understood of course that the means for operating the detentshown is by way of example only and that other means may be used or. substituted therefor. For instance a means may be employed beneath the car as illustrated in Figures 15 and 16. In said figures,'the equivalent of cable 95 is shown at 115 passing through a suitable tube 116, which may be rigid and secured to a part 117 of the truck of the car. A bell crank lever 118 is pivoted to the sleeve 116 as at 119 and cable 115 is connected to one arm of said lever. A resilient or spring section 120 is provided in the cable 115 so that slight vibratory action of the lever 118 will not draw the cable sufficiently to release the detent 85. The other arm of lever 118 is adapted to engage track obstacles 120 disposed at suitable locations along the roadway. With the engagement of levers 118 with the track obstacles, the levers are tilted which exert a drawing action on the cable 115 and accordingly elevate the detent. 85.

Changes in the details and principles may be resorted to within the spirit and scope of the invention since merely one practical embodiment has been illustrated and described.
