STATION INDICATOR Filed Nov. 5, 1935 3 Sheets-Sheet 3 A TTORNE Y.

Patented July 21 1936 UNITED STATES PATENT OFFICE 10 Claims.

This invention relates to station indicators or changeable signs adapted to indicate in railway carsconsecutively the next station at which the train will stop.

It is the object of this invention to provide an indicator. of this type which is mounted in the car and shall automatically and visibly show the name. of the next station.

It .is a further object of this invention to provide an indicator which is very simple in construction and is very easily installed in the car without extended alterations thereon and which may be operated from the outside thereof by very simple and inexpensive means. 7

It is another object to provide such an indicator that will operate when the car is moving in opposite directions.

With these and other objects in view, the invention consists in certain novel combinations and. arrangements of parts which will become cleareras the description progresses and which are illustrated in the accompanying drawings in which V p Fig. 1 is a front view of a station indicator embodying the invention, with the front cover and.

Fig? 13 is 'a' view partly in section and partly in elevation showing the operating parts of the improved indicator mechanism in engagement witha striker on a station platform.

Referring to Figs. 1 and 11 of the drawings, 50

represents the housing in which the station indicator is enclosed. It is preferably made of sheet metal and of rectangular shape in all three dimensions. The front opening is closed by a sheet metal cover shown in Fig. 11. It is provided 5 with a window 52 behind which the station names appear consecutively. The part 53 of the cover which is not open is preferably used for advertising matter.

Housing 50 is preferably mounted on the top transverse wall of a railway car near the ceiling where it may easily be observed by the passengers. From the right side of the housing 50 near its upper edge as viewed in Fig. 11 a shaft l4 projects.

It extends through the wall of the car and its 15 outer end terminates in a two armed handle lever I3 perpendicular to the shaft l4. This handle when turned clockwise operates the indicator mechanism presently to be described.

At the end of each station platform in the system stationary fingers or strikers 41' and 41a are suitably mounted, on posts 48 near the edge of the platform 49 as shown in Fig. 13. These strikers are positioned singly in the path of handle l3 on the moving car so as to be struck thereby when the car moves past it to operate the indicator in order to display the name of the next station in the window.

This indicator mechanism is shown in Fig. 1.

It includes a reversible universal electric motor I adapted to be energized by alternating or direct current. This motor drives a shaft 4 by means of a worm gear speed reducer 2. This shaft is perpendicular to the motor armature and carries at one end a motor brake wheel 3 and at the opposite end a spur gear 5 which meshes with a similar gear 6 driving a shaft 35 mounted in bearings 43. Between these bearings a reversing spring cam 36 is mounted on shaft 35, and on the end opposite to gear 6 a pinion is mounted (Figs. 2 and. 3). Pinion l meshes with swinging gear 8 shown as adapted to engage drum gear Be on drum or web-roll shaft 9b on which the web drum 9 is mounted to turn freely in bearings 90 and 9d.

This drum 9 carries a web ll of transparent canvas on which the names of the stations appear consecutively at equally spaced intervals. The web runs over two cylindrical bars or rollers 44 arranged in a plane parallel to the plane of the drum axes and may be rolled from drum 9 on to a second drum l0 mounted to rotate freely in a similar manner parallel to drum 9. Below each drum, a spring 42 is mounted on a bracket 42a on the floor of the housing, which spring acts as a poles suitably connected by conductors I90 to 7 terminals of the motor. The switch may be closed by moving the handle I3 clockwise and thereby rotating shaft I4 to which the handle is secured. A crank I401 on'the opposite end of shaft I4 will turn a crank; shaft tfiiby; means; of a connecting link 45, the shaft being ecqentrically mounted in bearing 41 (Fig. 6). The free'end' ofgshaft. 46, is connected to themovah je blades. of witch i9 and n this; manner the swit h is clo ed: nd he. motor star e 7 A. pcrtionof shafit 4.6; aterid ;in an pposite di-. rection from. bearing 41: and. forms. a. crank I,I- w n n invsaid bearing and. carrying; atzits, oscillatable. end a rooved wheel.

.Between drum 9: and bearing 90 a cam wheel 20 is mounted on shaft 9b (Figs. 1 and 8) to rotate with drum 9. A grooved wheel 24' is mounted on a crank shaft 22 and arranged so that the groove in its periphery is-in engagement withlthe periphery of cam plate 20. Shaft 22 is rotatable ina bearing 22c fastenedto the rear plate of housing 5fl and hastwo crank arms thereon indi: cated at'ZZa and 2219.. Arm 22a carries roller 24, and the free end of. the other arm 22b is connect- "ed to one end of a horizontal connecting rod 25a extends from side 'to side of the housing.

A. helical tension spring 23 has one end secured to an anchor 54 in the wall of housing and has its otherend connected to the arm 22a to urge said armand roller 24 towards the cam wheel 20.

This may be done by theconductor or automatically by extending shaft 33 to the outside of the car and by mounting handle 3| on the outside of the car wall with its end in-position to be struck by a suitable striker 41' or 41a mounted in its path. When handle 3| is actuated the drum which was idling before will then be driven by gear 8 which has automatically been placed in mesh with its drum gear by the action of reversing cam 36, spring 31 and lever 38.

The placing of striker arms at station platforms has tobe so arranged that when the car 54 is moving in either direction lever I3 is operated clockwise. For this purpose these strikers are arranged higher on the outgoing track than the return track to strike either the upper or the lower arm of handle l3. For example, as shown diagrammatically in Fig. 12, the lower arm of handle l3 may strike the striker arm 41a on the outgoing run, and its upper arm may strike the striker arm 41' on its return run. Of course, it

will be understood that these striker arms may be placed along the respective tracks either on the outside or inside as required.

Having thus described my invention, I want it to be understood that changes in details of construction may be made without departing from the principle of the invention and I desire to be limited only by the state of the prior art and the appended claims.
