Ta-aZZ whom it may concern.-

Be it known that we, DAVID C. EVANS and OLIVER Q. PATTERSON, citizens of the United States of America, residing at Unionindicatorv wi town, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Street-Car Indicators, of which the following is a specification, reference being had therein to the accompanying drawin s.

This invention re ates to certain new and useful improvements in indicators, and more particularly to that type of indicators adapted to be electrically actuated in connection with street and railway cars.

The primary object of this invention is the rovision of novel means for indicating the different streets and stationswhich a car approaches during the entire route of the car. In this connection we have devised novel and positive means for displaying the name of each street or station a car approaches, and to accomplish this we haveprovided a plurality of plates upon which the namesof the streets or stations which a car passes are placed, and by electrically-actuated means the name of each street or station is dis played prior to the arrival of a car at said place.

In constructing our improved indicator we have em loyed novel means whereby the l lbe automatically actuated, and the means which we have employed is constructed, whereby it will not interfere with the general construction of a railway, and the simple construction of the same reduces the expense of maintenance to a minimum.

The construction of our invention will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings accom anying this application, like characters of re erence designate corresponding parts throughout the several views, in whichindicator in side elevation.

"In the accompanying drawings we have illustrated a conventional form of 'streetcar 1, which is electrically operated, a trolleypole 2 and a trolley-wire 3 being employed or this purpose. Our innemion resides in the indicator 4, which we preferably mount" in the forward end of the car 1', wherebyit maybe easily observed by the occupants of the car. The indicator is constructed of a casin 5, having an open front 6, and transverse y of the casing adjacent to the open front we journal a shaft 7, upon which is mounted a ratchet-wheel 8, and upon this. shaft is mounted-at each end of the casing a toothed wheel 9, the teeth of said wheels forming recesses or grooves in the periphery thereof, as at 10. At each end of the casing we mount two tracks 11 and 12, the track 11 inclining from the rear of the casing to directly above the toothed wheel 9, while the track 12 inclines from the toothedwheel to the rear of the casing, as clearly illustrated in Fig. 3 of the drawings. Each track is substantially channel-shaped, and in each track is mounted a guide 14, this guide being sub- The rear end of each guide is closed by a plate 15, and between the tracks 14' 14 are mounted plate-holders-16, the number of plate-holders employed depending upon the number of streets along the routeof the car equipped with our improved indicator. Each-plateholder consists of a shaft 17, which carries depending grooved rods 17 17 and between these rods are mounted plates 18, upon which the name of a street or station is placed, as illustrated in Fig. 7 of the drawings, the name of the street being placed upon one side; while upon the reverse side of the plate placed. To retain the plate-holders 16 in position to be en gaged b the wheels 9, we suspend. a weight 16 in the rear of the plate-holders 16, said Weight being suspended from a track 16 roller 19, which is retained upon the ends of the shafts by nuts or the like fastening means. I The track 12 at each end of the boX is provided with an upwardl -extending spring-or resilient strip 21, whic is adapted to lie in engagement with the toothed wheels 9 9.

The strips 21 are pivotally mounted adjacent to the wheels 9 9, so they can be swung outwardly to remove any plateeholder that may be retained by said holder. In the casing 5 we mount an electromagnet' 22, said magnet carrying a pivoted arm 23, the one end 24 of said arm lying in close proximity to the core 25 of the said magnet, while the op osite end of said arm is connected to the plhnger 26, which normally has in engagement with the ratchet-wheel 8 of the shaft 7. "The-electromagnet is connected by wires 27 and 28 with the electrical circuit which operates the streetcar -1, the wire 27 passing upwardly through the car and along the trolley-pole 2 to an insulated contact-arm 29, carriedby the harp 30 of said pole, while the wire 28 is grounded by connecting it to oneof' the axles of the car or the likepiece of mechanism which will insure a positive circuit, as will be presently described.

At each street along the route of a car-line we provide the trolley-wire support 31 with a depending insulated arm 32, having a springcontact point 33. The arm 32 is connected by a Wire 34 with the trolley-wire 3, and the operation of our improved indicator is as follows: We will first assume that a street-car is at the terminal of a line and it is about to traverse the route over which it travels. The

plates 18, carrying the names of the streets along1 the route,.are laced in the tracks 11 is being accomp ished by placing guides 14 14 in the tracks 11 11, which carry the lates, and the platesare preferably arranged in a vertical position, as illustratedin Fig. 3 of the drawings, whereby the one side of each late will be displayed through the open out of the casing. When the plates are carried by the tracks 11 11, the names of the streets are displayed-as, for instance, in Fig. 7 of the drawings we have illustrated the street Penn Aveand owing to the inclination of the tracks 11 11 these plates,which are carried by the rollers 19 19, will gradually travel down toward the toothed wheels 9, 9 and eventually drop into one of the recesses or grooves of said wheels." By referring to Fig. 3 of the drawings it will beobserved that the top edges of the .plates engage the front of the casing 5, and (when the toothed wheels are actuated by the electromagnets 22 the plates will be released and 'ermitted to drop by gravity to a position w ich will display the reverse side of the plate, as illustrated in Figs. 1,3, and 7 of the drawings. In this manner first-one name of the street will be displayed, and upon the car traveling to the next street the advertisement which was carried by the rear side "of the plate will be displ-a 'ed. The springs 21 21 serve to re- 'tain t e rollers 19 in enga enientwith the toothed wheels 99, and-a ter these wheels have rotated'sufiicient to release said rollers they are engaged by the tracks 12 12, which convey them to the rear side of the casing 5, assembling the lates in the order in which they were place in the tracks 11 11. When the terminal has been-reached by the street-' car, the guides 14 14,retaining the lates, are removed from the tracks 12 12 and replaced in the tracks 11 11 in order to be used again when the car traverses its route. As each car approaches the street the contact-arm 29, carried by the trolley, will engage the springcontact 33 carried by the depending arm 32 of the. trolley-wire su port, and a circuit will be completed throng the trolley-wire 3 to the source of electrical energy A, through the ground'B, wire 28 to the electromagnet 2'3, and throu hwire 27 to the arm 29,which will energize t 1e electromagnet 22 and attract the pivoted arm 23 and rotate the ratchetwheel 8, which will in turn rotate the toothed wheels 9 and display the name of a street each time the electromagnet is actuated.

In Fig. 1 1 We have illustrated a truck 40 of an ordinary railway-car in connection with which our indicator may be used to designate,

the various stations along the railroad. The

truck is provided with depending arms 41 41,

representing the positive and negative poles of the electrical circuit used-with our indicator. The track 42 adjacent to each station is provided with a resilient contact strip 43,

adapted to complete the circuitof the indi,

cator and actuate the same to display the name of a station. In each indicator we arrange an alarm 44, suchas an electric bell, and this bell is cut in upon the indicator-circuit to sound an alarm at each station or street approached by a car. In connection with the electrical circuit of the indicator we may employ a button or switch 45, located convenient to the operator of a car, whereby when a street or station is passed by without stopping and track or trolley contact should fail to work the operator can easily close the indicator-circuit, actuate the same, and thus insure a'perfect-operation of the indicator.

The indicator may be suitably supported within the car by any desired means, in the present instance we having illustrated screws 35, which secure the ends of the indicator to the body of the car,

The indicator is pref-- erably providedlwith a hinged door. 36, whereby the indicator can be conveniently opened from the platform of a car and the plates 18 transferred from the, tracks 12 to the tracks 11 or additional plates placed therein, according to the route over which the car passes.

It will be observed that we have provided an inexpensive and easily-operated streetindicator, which can be also used as an advertising medium, and while we have herein described the preferred manner of operating our improved indicator it is obvious that various changes may be made in the details of con struction without departing from the spirit of the invention as defined by the appended claims.

What we claim, and desire to secure by Letters Patent, is

1. In an indicator, the combination with a street-car, of a casing mounted within said car, inclined tracks carried at each end of said casing, guides mounted in said tracks, movable plates carried by said guides, toothed wheels revolubl y mounted in said Casing, and adapted to engage said plates, means for sustaining said plates in engagement with said toothed wheels, means for temporarily holding said plates in vertical position while engaged by the wheels, said last-named means being adapted to permit the plates to be successively released so as to turn over by gravity and reverse their position, an electromagcator is actuated.

2. An indicator of the typedescribed, comprising in combination a casing having an open front, inclined tracks mounted in said casing, guides carried by said tracks, plates movable by gravity in said guides, toothed wheels journaled in said casing and adapted .to successively engage each of said plates,

means to hold said plates in engagement with said Wheels, means to sustain each plate temporarily in vertical position while engaged by the wheels, said last named means being adapted to permit of the plates being successively released so as to permit them to reverse their positions by gravity while engaged by said Wheels and means to actuate said wheels.
