With these objects in view my invention consists in certain details of construction and arrangement of parts :.ll as will be hereinafter fully described andpu rticularl y pointed out in the appended claims.

My invention will be niore readily understooi by reference to the accompanying drawings forming a part of this spccitieation, and in which,

'Uien-.ovmcentrally through the cas- 90 ing. A leaf sp'ng 16 secured at. its center to the membornthe extieniitiestheof respectively einltging' corresponding ilang of said :.pwlf, is evidently adapt to ho s the latter a nmst relative lateral movement.. Q Each of sad spools is preferably provided with a pwfpheral longitudinally extending .slot l?. llaving their outer en s securedat the rxtrenities of each of said slots, are iiiwardlv lmgitudinally extending rods 17 the 10 adjacent extremities of which are spaced as shown. The extremities of the ribbon 15 being provided with loops 18 adapted to be engaged by said rods 17', usi clearly shown l. in Fig. T, n detachable ettcient. connection between the former andthe spools 14 and 1t is evidenti made possible. Arranged upon either si( e of the ribbon 15, the saine beiner equally spaced thereon is ii plurality 'ol' indications individually visible through 11 l of the plates 6. `In

19 formed in either drawings the naines of streets or crossings passed by the car upon which the device is arranged, are shown, said indications being. arran upon said ribbon in the order in whic i the car in traveling in one direction crosses the streets or successively indicated thereby. Fix to the shafts 10 and 11, the same being positioned thereon so as to rotate adjacent the inner surface of the member 3 are disks 20 and 20' respectively. Pivo at 21 u n the inner surfaces of the disks 20 and ane pawls 22 and 22 respectively glam covered openings e "said pawls as shownbeing in the forms o bell crank; levers. Leaf s rings 2b exert forces upon said pawls ten ing to normall hold the same in o rative engagement wi pinions 24 and 24 fixed to the adjacent extremities of the spools 14 and 14', said pawls evidently serving as a means of establishing an operative connection between shafts 10 and 1l. and their respective spools 14 und 14'. As stated the indications upon the ribbon 15 are equally spaced thereon, hence in the operation of the device said ribbon must needs, upon each actuation, be fed an equal distance in order to suceessivel dis lay the indications thereon. Inlorder i etilct such feedi of the ribbon Yprovision is male whe y, when feeding the ribbon in one direction, the one of the spools 14 or 14 u n which the ribbon is being coiled sha1 be driven or operatively connected with its shaft 10 or 11, while the other tspool shall be loose u n its shaft whereby e pa out of the ribbon coiled thereon w' -be governedhy the demand for it as created y the driven receiving spool; and whenet such conditions will bereverscd when f ing the ribbon in the other direction. With such provision in view, the disks 20 and 20 are rovided with similar irregular cam mem rs 25 and 25' respectively rotatably mounted thereon. Said cam members sopositioned upon the disks 20 and 20', that the inoperative ends of the pawls 22 and 22 rest in ent therewith as clearly shown in Fi 8, each of said cama being of such form t at when said end portion of the pawl coacting therewith is restf ing in engagement with the-face 26 thereof the engaging or opposite end of the pawl will be in operative position that is w l be permitted to engage the teeth of its coacting pinion 24 or 24'; and that when said cnil portion of the pawl is restii in engagement with the face 27 thereof, e engaging end of the pawl will bc in inoperative posi-- tion. Formed at the upper and lower ends of the casing member 3 concentricall with the axis of the shaft 11, is a iluralitv of spaced inwardly projectin' tee 28. Said teeth are so itioned a the cams 25 and 25 so fo that the corners 29 of the latter, upon .the rotation of the disks 20 and 20' will engage said teeth as clearly shown in Fig. 8. "urther said arrangement is such that upon rotation in one direction of the connecting chain 13 the cams 25 and 25 will be actuated by the teeth 28 to cause one of the pawls 22 or 22 to be positioned to cause locking of one ofthe spools 14 or 14 to its shaft and the other pawl to be positioned to etect the free movement of the other spool upon its. shaft; and that upon notation in the other direction of the connecting chain, the cams 25--25-wil1 be partially rotated by reason of the contact of the teeth 28 to a position to cause ,the reversion of the results above stated. Such construction is clearly shown in F 8. lVith such provision it is, therefore, evident that in whatever direction the chain 13 is driven oneof the spools 14 or 14 will be automatically released for uncoiliiig and the other locked for receiving of the indicator ribbon.

Secured as by screws 30 to the upper epd of the casing 1at one side thereof, is a second auxiliary substantially' cylindrical casing 31. journaled in bea rovided in the end walls of the casing 1 is a shaft 32. .Fixed to said shaft adjacent the inner end wall of casinglisa rwheel88m witha pinion 84 tix to one extremit of e shaft 10. Also fixed to said shaft, esame beii 'tioned thereon adjacent the H a air of ratohts. wheelsl ed aving eir inner en rocking y moun upon said shaft are two upwardly extend' rocker arms 87 and 88, the former being bi ted at its attaclied end to receive said end of the other. A circular split leaf spring 89 the ma ve extremities of which engage notches prcvided in the lowerextremitiea of the arma 87 and 88 is adapted to normally hold said extremities of the latter in contact or in close proximity with each other, and consequently theupper ends' thereof in divergent positions, as clearly shown in Fig. 10. Having their outer ends upon studs 41 proj from inner aides of the arms 7 and 8 are pawls 42 and 42' respectivel Coiled com ression springs 43 arra in housings formed upon the arms 7and88,en thefreeendaof the pawls 42 and 42 are apted to normally an inwardl directed force upon the latter. The paw 42 ia so positioned that upon inward rocking of arm 37, the saine will en the ratchet 35 to cause a partial rotation ereof, and the pawl 42 is so ositioned that upon the inward rocking o the arm 88 the same will engage the ratchet 36 to cause the rotation thereof in a direction o posits to -that of the rotation imparted tf tiie ratchet 85 by the pawl 42. Formed oi the inner surface of the casing 31 are in- Having its extremities centrally h sin si. i

.dimm 'um when' as slot 53 -squar as clearly s wardly extending curved shield plates 45 so positioned and of such curvature as to extend in close proximity to and to cover the end lportions of the upper peripheries of the rata, iet wheels 35 and 36, as clearly shown in' Fig. 4. Said portions 45 are of such length as to be enga d by the free ends of the pawls 42 and 42 when the arms 37 and 38 are in normal outwardly obliquely extending position, hence said portions will normally eii'ect the disengagement of said awl from their respective ratchets 35 an 36. With such provision it is evident that the feeding of the indicator ribbon upon the spools 14 and 14 as in a manner before described may be readily effected by the rockin actuation of the arms 37 and 38;

raversing the interior of the casing 3l,

.the saine being secured thereon by snows 46 threaded into formed upon l'ie inner surface ofthe casin v is a plate 47. Journaled in said plate in a position -parallelly extendin and in vertical alinement with the shaft 32 is a shaft 48. Carried at the inner extremity of said shaft is an eccentric 49 the saine being so positioned as to traverse the path of rotar or oscillatory movement of the ears 50 an 50 formed upon and pro'ecting from the outer longitudinal edges o the arms 37 and 38 res tively, such arrangement bein clearly s own in Fig. 10. Said eccentric t ereby cvidently'forms a stop to limit the extent of inward ovement of said arms. Fixed to said shaft 48 at the opposite side of the plate 47 is a beveled gear 51 and to the outer extremity thereof is un indicator arm 52 the otiset outer extremit =y of which projects through a circular graduated formed in the outer end wall of the casing 31. Loosely mounted upon the shaft 32 is a worm 54 operatively connecting which and the gear 51 is a ear 55 mounted ir. a bearing 56 secured to t e plate 47, as clearly shown in Fig. 6. The outer end of said worm rojects throu h the casing 31 and is iown in Fig. 6, to rcceive a disk 57 through tbe medium of which said worm may evidently be rotated.

Mounted upon the squared outer end of the shaft 32 is a disk 58 held in position thereon by a cotter pin 59. Formed upon the periphery of the disk 48 tre outwardly extending liifurcated ears 60. ,'Ihrcaded in an outwardly projectin ear 61 formed at the periphery of the disk 57 is a thumb screw 62 the inner extremity of which is adapted to engage the bifurcations in thc ear as clearly shown in Fig. 5. lith auch provision it is clear that said screw 6% forms a means of o ieratively connecting the worm 54 in the sha t 32. By .auch provision, by simply unscrcwing said screw to discrigement with the ears 60 the shaft 32 may rotated independently of said worin ,und hence of the gear 51 and the eccentric 49.

B521 the provision of said eccentric arranged an as shown and described, the same will automatically regulate the extent of vibration or oscillation of the arms 37 and 38 in such a manner that the length or extent of indi cater ribbon uncoiled from one spool and coiled upon the other upon each feedin thereof will be constant, in other words sai eccentric isof such design as to restrictV the extent of 'vibration of one of the arms 37 or 38 when the spool actuated thereby is carrying the majority of the ribbon, hence when said spool is of increased diameter, and at the same time to permit of the corrcspondingly greater extent of vibration of the other arm since in such instance the spool actuated thereby will be cai'i'yin a lesser amount or the minorit of the rib on hence will be of decreased diameter.

By the provision of the indicator arm 52 the exact position of said cam relative to the arms 37 and 38 may be readily ascertained. And by the provision of the means for operatively connecting said cam to the main shaft 32, namely, the disks 57 and 58 und the connectin screw 62, said cam may be readily adjustc to correct] sition the same relative to the position o t ie indicator.

ribbon on the spools 14 and 14.

The arms 37 and 38 project through a slot 63 formed in the upper side of the casing 31 and are each provided with' a projecting lug 64. By means of cords 65 secured to said lugs and passing over and operatively connected with the shaft 32 around pulleys 66 mounted in housinv 67 formed on the upper side of the casing 31, as clearly shown in Fig. 2, said cords when the device is arran ed in a car extending to either extremity of the latter, said arma 37 and 38 may be rocked by the conductor or other personage from any position in which he may be in the car.

The operation of the device is evident. The device being arran d in a car with the indicator ribbon provi ed with the names of the streets or crossings successively arranged thereon in the order in which the saine are crossed by the car all that is required in order to operate the device is to draw or pull one of the cords 65 whereu n the names of the streets will be disp ayed so as to be visible from either side of the device. TVheii traveling in one direction one of the cords 65 will be o rated to feed the indicator ribbon in one irection, and when traveling in the other direction the other will be operated to reversely wind said ribbon since. in traveling in the opposite direction the order in whichthe streets are crossed is reversed.

While I have shown what I deem to bc the preferred form of my device I do not wish to be limited thereto `urtherc might be various changes niadc in the details` of construction and arrangement. of parts without departing from the spirit of the iiiveiition coin irchended within the sco of the appende eluinis. And althouh have designed my device with specia refeicnce to ita use as a streetindicntor in a railway carr I may use the same for any other purpoee to which it in applicable.
