WILLIAM B. RILEY, OF PALESTINE, TEXAS, ASSIGNOR OF ONE-HALF TO JOHN A. TEAMER, OF PALESTINE, TEXAS.
OPERATING DEVICE FOR AIR-BRAKE ANGLE-COCKS.
SPECIFICATION forming part of Letters Patent No. 722,384, dated March 10, 1903. Application filed May 29, 1902. Serial No. 109,556. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM B. RILEY, a citizen of the United States, residing at Palestine, in the county of Anderson and State of Texas, have invented a new and useful Operating Device for Air-BrakeAngle- Cocks, of which the following is a specification.
The invention relates to certain improvements in air-brake systems, and has for its principal object to provide an improved means for efiecting the opening and closing of the angle-cocks located at each end of the trainpipe section carried by the various cars; and
it consists in the arrangement of a system'of levers whereby the angle-cock may be operated by the brakeman from either side of the car and without the necessity of going between the cars, as at present practiced.
In the accompanying drawings, Figure 1 is a plan view illustrating a portion of a trainpipe and showing an angle-cock provided with operating-levers in accordance with my invention. Fig. 2 is a detail view of the doubleended lever secured to the stem or key of the angle-cock. ,7
In opening or closing the. angle-cocks of train-pipes as at present practiced the brakemen are compelled to go between the cars in order to reach the handles of the cooks, and with many of the cars now built this operation exposes the men to danger of being crushed between the cars.
In carrying out my invention I employ an angle-cock 5, having a stem or key 6, to which is secured a double-ended lever 7, said lever being provided with a downwardly-depending stop-pin 8, adapted to engage with stopshoulders 9, arranged on the valve-casing at about ninety degrees from each other and serving as fixed stops, determining the open and closed positions of the angle-cock. To properly support this pin, the'lever is provided with an ofiset 10, as more clearly shown in Fig. 2, and the relative arrangement of the stop pins and shoulders is such that in each of its two positions the axial line of vthe lever will be at about an angle of forty-five degrees from the central line of the train-pipe. To
each end of the lever is pivotally connected a rod 11 of a length sufficient to extend to the side of the car, each rod being provided at its outer end with a handled portion 12 and supported in place by a small bracket depending from the side sill of the car.
I In the operation of the ordinary angle-cock the operating-handle is in one position in direct alinement with the train-pipe and in the oppositeposition is at a right angle to the trainpipe. In the present case such position of the lever would not answer unless the connecting-rods leading to the sides of the car were arranged on lines at approximately forty-five degrees to the line of the train-pipe, and such a position could not be obtained in practice, owing to the fact that the angle-cock is generally disposed very near the extreme end of the car-frame. In the present case the position of the parts is such that the angle-cock may be opened from either side of the car by pushing in on one of the connecting-rods. To close the cock, one or other of the handles is pulled outwardly until the stop-pin comes into contact with one of the stop-shoulders. This operation is extremely simple and will be readily remembered by the brakeman, so that there will be little or no danger of accidentally placing the cock in wrong position, while alldanger resulting from reaching between the cars is avoided.
Having thus described the invention, what I claim is-.
The combination in an air-brake apparatus, of the train-pipe, an angle-cock having a stem terminating in an angular upper end, a lever 7 provided at a point intermediate of its ends with an opening adapted to fit over the angular end of the stem, said lever normally occnpying a position at about an angle of fortyfive degrees to the line of the train-pipe when the angle-cock is in either open or closed position, stop-shoulders 9 disposed on the body of the valve and spaced from each other by an arc of approximately ninety degrees, an offset portion 10 forming an integral part of the lever and projecting from one side there- 5 set portion and adapted. to engage with the stop-shoulders 9, and handled connectingrods 11 pivotally connected to the opposite ends of the 1ever7and extending respectively 5 to opposite sides of a railway-carriage, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
WILLIAM B. RILEY.
