Application filed August 5, 1907. Serial No. 387,100.

To all whom it may concern:

Be it known that I, IIENRY L. Kennels, a

citizen of the United States, residing at Lundys- Lane in the county of Eric and State of Pennsylvania, have inventedcertain new and usefui Improvements in A0- tuating Mechanism for Station-Indicators; and I do hereby declare the following to pea full, clear, and exact description oft-he nvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification;

This invention relates to station indicator operating mechanism, and has for its object the construction and installment on cars of mechanism for automatically operatingsta- 20. they move along the roadway.

I The features of my invention are hereinafter 'fully set forth'and explained and diagrammatically illustrated in the accompanying drawings in which:

depressed as the flanges tion indicator mechanism in such cars as Figure 1. shows diagramn'iatically a mechanism embodying my invention installed on a car. F 2 shows a detail of one of the stops in the roadway forming part of my apparatus. I

In these drawings A is a portion of a rail road track; B B portions of car-trl'icks;

C'a compressed air tank commonly used in connection with brake and other mechauismv on cars, and D a station indicator in a car. On the car trucks B B I mount arms E E in which I- pivot swinging levers a a each provided with a spring 6 to normally retain the levers e e in a perpendicular position just inside of one of the rails of the track, and in the road-hed adjacent to said.

rail I place a stop F preferably made to be of the truck Wheels pass over it; a pre erable ty e of which stop F and its location relative y to the rail is clearly shown in Fig. 2. The object of lacing'the stop in the path of the wheel ange and making it depressible is to presentas little obstruction to vehicles on the street surface as possible. From the levers e e flexibleconnections e and lead to studs on opposite sides of a Wheel G supposedly mounted on a car-body supported -by tli'e trucks B B, so that as the car moves in the. direction of the arrow a the lever will engage the stop F and rotate the wheel G, while the lever c'-will pass over the stop without affecting it; and vice versa,-.

when thecar' is moving in the direction of the arrow at" then the lever 6 will so engage the stop F as to rotate the wheel Gl' From the" wheel G a belt g-,'preferably of sprocket-chain construction, extends to and around a suitable pulley H onthe stem of an ordinary three-way valve not specifically shown) mounted in a pipe. 0 leading fromf the air-tank G, to a cylinder I, so that when the valve is opened air will pass through the pipe 0 from the tank G into the c linder I and move thepiston 1 against t e spiral spring P, so as to communicate the motion of the piston I" through the rod i to one arm.

of a bell-crank lever J, the other arm ofwhich connects by means of a rod with one arm of a second bell-crank lever'L, the other arm of which is connected by means of a rod with a station indicator D, which is thereby actuated. For the purpose of allowing the spring I to move the piston If back to its normal position ready to again operate, I

make exhaust openings 2"and i in the 01dinder I, the exhaust opening a" connecting with a small cylinder N in which there is apiston provided withni racked bar n which inter-meshes with a segment of gear h on the shaft of the three-way valve in the pipe 0,

which when the head of the piston I passes the opening .71 in the cylinder I allows air to pass from the cylinder I into the smaller: cyl-.- inder N,-which operates to drive the-piston clearly obvious that further description thereof is deemed unnecessary. Therefore hav ing shown and described my invention so as to enable others to construct and operate the same,

a The combination of a station indicator ac-- tuating mechanism and av car, comprising substantially, a car, -an actuating cylinder and piston, and a station indicator, means connecting said piston with the station' indihat I claim as new and desire to secure byLetters-Patent is:

from for closing said va1ve,-substantia1ly as 10 set forth.

In testimony whereof I affix my signature, in presence of two witnesses.

HENRY L. KEELER.
