T 0 all whom it may concern Be it known that I, EnwAnD T. MCGABE, a citizen of the United States of America, residing at Cleveland, in the county of Cuyaho'ga and State of Ohio, have invented new and useful'lmprovements in Street Registers or Indicators, of which the following is a specification.

The 'objectof the invention is to provide a simple and eflicient and relativelyinexpensiv'e mechanism for use in connection with tramway and other cars for successively and automatically indicating the names of street or stations-as they are respectively approached in the progress of the vehicle as a means of convenience to the passengers and to avoid the necessity of having the streets or stations called bythe conductor or other train men or attendants and under such conditions as to insure accuracy in the display of the proper name or indication at such times or at such points relative to the progpage points of the car.

ress of the vehicle as'may be deemed proper andjconvenient regardless of the varying intervals between stations and streets or'stop- To this end the mvention consists in 'a construction and combination 'of parts of which a preferred embodiment is illustrated in the accompanying drawings it being understood that changes in form, proportion and details maybe resorted-to within the scope of. the claims without departing from the 7 principles involved.

In the drawings: 7 v a r Fig. 1 is a plan view in diagram to illuse trate the means and arrangement of parts whereby successive impulses are given bythe motive current of the railway system to the station indicating apparatus contained with in the car.

Fig. 2 is a view of the means. whereby the impulse is conveyed from the current carryingconductors tor the motive current to the apparatus within the car. I Fig. is a detail view ofthecontact carried by the car apparatus by which engagement is made with the current distributing elements located respectively adjacent to the stations orstopping points of the car or vehicle. I f i v Y Fig. 4 is adetail view of the. station indicating apparatus located within the, car.

Fig. 5 is ajdetail, sectional view of a storage roller employed for one end ofthe, station indicatingftape. I

6*6- of V s 7 Fig. 7 is a similar view of the stop mecha- FiglGis a similar view ofthe means for transmitting motion from the motor to the operatin drum of the indicatoron the plane nism forlimitingthe movement of the operating drum on the plane'7-7 of Fig. 4.

Fig. 8 is a'transverse sectional view of the tape carrying mechanism on the plane indicat'ed by theiline 8-8 of Fig. at.

' In Fig. 1 there is illustrated a general view of the track rails 10 trolley wires 11 and feeders 12 of a trolley" car system, a car '13 being indicated in relation thereto, andconnected with 'thecurrent carrying elements of the system there is shown a contact elementl one of which is, designed for 'lo cation at a. convenient distance from each stationor crossing at which a car traversing the track, is to stop and designed to be charged with the current ofthe systemffor communication to a complementary contact element 15 in the form of'a wiper adapted to be carried by the trolleypole 16 of the car as the latter in traversing the track brings its trolley' wheel 17 in proximity to said charged contact.' The conductor 18 by which the current received bythewiper'lti is conveyed to the interior of the car is entirely independent of the conductor 19 which constitutes a branch of the power circuit obtained' from the contact of the trolley wheels'with the trolley wire 11 and which branch. is provided within the casing20 of the station indicator with a 1 terminal I 21 forming one element of; ac irc'uit closure of which the movable element'22 is carried by a plunger rod .23. The circuit of which the conductor'lgforms an element is continued at 19 beyond the movable element 22 of the circuit closure to amotor'24t preferably located within the casing 20'andfsaid circuit is grounded as at 25 andv included therein is a reverse switch 26 to providefor the reversal of the directionof movement of the moton J r The spindle 27 of the motor is provided with, a worm 28 engaging a worm gear 29 on the spindle 3O carrying an operating roll 31 which is, arranged in operative relation with web close to'the plane of a display opening 36 in the front wallof the casin so that the name of the station exposed t rough said the sur ace of the operating roll 31 by means a.

ofpivotal bracket arms37 to which may be attached an actuatingspring 38. As the means for advancing the web or tape consists of the roll 31the accumulationof the web upon the drum 33 will not affect the extent of movement which, therefore, may be regulated to suit the distance between the indications or stations on the web or tape.

In circuit with the feedwire 18 which includes. the wiper 15 is a ma net 39 of which, the armature 40 918 carried, by the plunger 23 supporting the movable element of the circuit closure by which the motor actuating the circuit is controlled, said armature normally being held. yielding'ly out of contact with the magnet by means of a spring 41 or the equivalent thereof. Carried by .thespindle 30 of the web or tape operating roll is a stop disk-42 having a notch or seat 43 for engagement by a stop 44 carried by and consisting of a terminal of the plunger 23. When the stop is in 'engagement with the seat the web or tape feeding roll is held in a fixed position to display a given stationindicating the name through the display opening of the casing and upon the disengagement offlthe stop 'from its seat in the disk 42 the spindle of the roll is free to rotate under the influence of the motor which is included in the operating circuit 19,19 by the movement of the circuit closure element 22 into engagement with the contact 21-. The closed relation of. the elements of the circuit closure is maintained by the engagement ofthe stop 44 with the periphery .42 until the seat is broughtinto registration with said stop whereupon the plunger is depressed .by the spring 41 to break the circuit between the contacts 21' and 22. The worm gear 29 .is preferably engaged frictionally with the spindle .30 so that any movement ofTthe motor spindle 27, due to inertia, after the breaking of the motor circuit which. is ac? companied by the lockingof the feed, roll through the engagement of the stop 44 with the seat 23 will permit the said gear to slip onthe spindle without injury to other parts of the mechanism. Obviously contact: 21 may be adjusted to insure the properand effective closing of the motor circuit when the magnet is energized through the contact of the wiper 15 with the complementary contact 7 element of the power system, the energization offthe magnetv being accompanied'b the contraction of the armature 40 and t erelease ofthe locking means by which the Web or tape operati g mally docked against movement.

011 is nor- The storage'drum 34 is preferably pro movement of the storage drum under the tension of its actuatingspring 15 to take up the web and thus rerolling it thereon,

It will be understood that by reason of the actuation of the indicator occurring only when thefwiper 15 encounters the complementarycontact for a given station or stop, and it being possible to arrange said complementary contact wherever it may berequired for causing an adjustment of the stations is nglgligible, as a factor in deter; mining thee ciency of the device, and the extent or the movement of the web or tape Vindicator, the relative distances between hearing the station indicating names is con trolled by the circumferential extent of the A H disk or movable element of the stop mechanism which serves to maintain thejmotor c rcuit closed. only until the proper move ment of the web or tape has been secured,

whereuponit is again locked and held with the web in a fixed position until the engagement of the wiper with the succeeding contact of the track system causes a further retractionof the plunger to release the stop disk and close the motor circuit. l
