GEORGE SCHNEIDER,'OF HAMILTON, NEW YORK.

TRAIN-STQPPING APPARATUS.

Application filed April 3, 1914.

To all whom it may concern:

Be itknown that I GEORGE SCHNEIDER, a citizen of .the United States, residing at Hamilton, in the county of Madison and State of New York, have invented new and useful Improvements in Train-Stopping Apparatus, of which the following is a specification;

This invention relates to improvements in train stopping apparatus and has particular application to apparatusfor operating the engineers brake valve of the air brake system of acar .or train in the event ofthe car at a minimum expense and which will embody few parts and these so correlated and arranged as to reduce the possibility of derangement to a minimum.

With the above and other objects in View, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

In the accompanying drawings; Figure 1 is a diagrammatic side elevation showing my invention installed. Fig. 2 is a view in elevation of the car carried mechanism removed from the car. Fig. 3 is a top plan view of such mechanism. Fig. 4 is a longitudinal sectional view through a detail of the mechanism. Fig. 5 is a transverse sectional view therethrough.

Referring now to the drawings in detail, 1 designates the trackway which is preferably divided into blocks and located at the entrance to each block is a semaphore embodving a signal blade capable of movement to danger and clear positions. At the entrance to each block is located some suitable form of track instrument and, in the present instance, this instrument comprises a horizontal arm 2 journaled in suitable bearings 3 carried by one of the ties upon the outer .side of one line of rails, and an arm 4: 901

nected with the arm 2 and disposed at right angles to the latter and capable of movement to horizontal and vertical positions. The arm 2 is connected through suitable mechanism with the signal blade of the adjacent semaphore and when the blade goes to danger position the arm 1 is actuated to vertical position, while when the signal blade denotes clear the arm 4: is horizontal.

The car carried mechanism is adapted to actuate the engineers brake valve to effect an application of the brakes to the wheels and comprises a cylinder 5 within which is mounted for sliding movement a piston 6 equipped with a piston rod 7 extending outwardly of one end of the cylinder. The pistonrod end of the cylinder 5 is formed with an outwardly projecting block 8 having the outer end thereof con'caved as at 9 .and de signedfto fit against the side wall of the casing of the engineers brake valve, while fastened to the outer edge of the block 8 at the opposite ends of the concavity 9 and embracing the engineers brake valve casing is a strap 10 cooperating with the block 8 to hold the cylinder 5 connected with the valve casing and in a plane at right angles to the latter. A vertical rod 11 has the upper end thereof working within a bore formed in the block 8 and the lower end extending through the floor of the cab of the locomotive. Depending from the floor of the cab is a bracket 12 and fulcrumed within the bracket 12 is a bell crank lever 13 having a horizontal limb and a vertical limb depending from the horizontal limb. The horizontal limb of the bell crank lever is formed with a slot 1 1 in which is mounted a pin 15 carried by the rod 11, while connected with the lower end of the vertical limb of the bell crank lever is a rod 16 having the outer end thereof pivoted upon a pin 17 extending upwardly from a trip arm 18 fulcrumed upon a vertical post 19 depending from the bottom of the cab. This trip arm 18 extends outwardly of one side of the locomotive and is capable of horizontal swinging movement and under normal conditions projects outwardly from the adjacent side wall of the cab at right angles thereto. On the upper end of the rod 11 is a block 20 normally disposed. in the pathof movement of the piston rod 7 and in engagement with the latter. Connected with the piston 6 in the cylinder 5. and

extending outwardly from the end of the cylinder opposite from that through which the piston rod projects is a rod 2]., a coiled expansion spring 22 having one end abutting the piston 6 and the opposite end in engagement with the adjacent end wall of the cylinder 5.

In operation, should a train pass a set danger signal the trip arm 18 will impact against the vertical arm 4 of the track instrument whereby the trip arm will be swung horizontally. In the horizontal movement of the trip arm motion is imparted to the bell crank lever 13 through the medium. of the rod 16 and the bell crank 1e ver slides the rod 11 with the effect to. move the block 20 out of the path of movement of the piston rod 7 thereby enabling the spring 22 to react and slide the piston within the cylinder 5. In the sliding ot the piston under the action of the spring 22, the outer end of the piston rod 7 engages the handle of the engineers brake valve and actuates the latter to eiiect an. application of the brakes to the wheels. By means of the rod 21. the piston may be restored to normal position against the action of the spring 22 when such is desired.

In the present instance, the lower end of the pin 17 is headed and interposed between the headed end of such pin and the adjacent face of the trip arm is a coiled. expansion spring 23 acting to hold the rod 16 and trip arm 18 in axial alinement under normal conditions so that the block 20 will remain in the path of the piston rod 7 whereby the engineers brake valve may be manipulated in the usual well known manner.

YVhile I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claim without departing from the spirit of the invention. 7

I claim:

In a train stopping apparatus, in combination, a housing, a projecting lug mounted on said housing at its bottom, a rod slidahle centrally in said housing, a piston on said rod disposed in said housing, a coiled spring surrounding said rod and bearing against said piston and the adjacent wall of said housing, said lug having a vertical opening, said spring pressing said rod advance of said opening, a valve mechanism disposed adjacentsaid lug, a lever for actuating said mechanism projecting in a path of movement of said rod adapted to be pressed by said spring against said lever to operate the same, a "ertically reciprocating rod projecting above said opening, a head formed on the upper end of said last named rod serving as a fixed abutment for said rod in the housing, said first named rod engaging said head against the tension of said spring, and means engageable with said last named rod to operate it whereby to cause said head to move below said first named rod.

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

GEORGE SCHNEIDER.
