AIR-BRAKE DETAIL.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed April 26, 1913. Serial No. 763,913.

T 0 all whom it may concern:

Be it known that I, BENJAMIN'W. DAVIS, a citizen of the United States, residing at Evanston, in the county of Uinta and State of lVyoming, have invented a new and useful Air-Brake Detail, of which the following is a. specification.

The device forming the subject matter of this application, is adapted to be employed for manipulating the angle cocks in the train pipe line of an air brake system.

This invention aims to provide a means for controlling the angle cock of a train pipe line in an air brake system, which means may readily be assembled with an angle cock of standard construction, without making changes in the angle cock.

The invention aims further, to provide a device of the type described which will not be subject to injury when the draw bar is extracted, or when the car is chained up.

Another object of the invention is to provide a means for controlling the angle cock, which means will be within full view of the operator, and be entirely accessible for repair.

I The invention aims, as another object, to provide, as an article of manufacture, an angle cock cont-rolling means, one element of which at the will of the operator, may be omitted, so as to vary the height at which the operating handles are located with respect to the angle cock.

It is within the scope of the invention to improve generally and enhance the utility of, devices of that type to which the present invention appertains. I

Vith the above and other objects in view which will appear as the description proceeds, the invention resides in the combina-' tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows in top plan, a car to which the device forming the subject matter of the present invention has been applied; Fig. 2 is a side elevation of the structure shown in Fig. 1; Fig. 3 is an end elevation of the sill of the car, showing a portion of the present invention assembled therewith; Fig. 4 is a side elevation of the standard; Fig. 5 is a bottom plan of the standard; Fig. 6 is a plan of the lever which is assembled with the standard; Fig. 7 I

is a side elevation of one of the slide bearings through which the operating handles move; Figs. 8 and 9 are sectional details of the angle cock, the valve thereof being disposed in different positions, and F ig. 10 is a side elevation showing the lever applied directly to the valve. I

In the drawings there is shown a car 1 provided with an end sill 2 and with a draw bar 3, the train pipe being denoted by the numeral 4 and the coupling hose by the numeral 5. The angle cock mechanism connects the train pipe 4 with the coupling hose 5 and preferably is of standard construction. The angle cock, however, may include a casing 6 provided at one side with a bleed port 7. J ournaled in the casing 6 is a valve 8, provided at its upper end with the usual polygonal lug 8 indicated in Fig. 2. The valve 8 is equipped with a transverse passage 9 adapted to form a communication between the train pipe 4 and the coupling hose 5. The valve 8 is further provided with a side port 10, opening into the passage 9 and adapted to establish a communication between the passage 9 and the bleed port 7.

The invention includes a standard 11, shown in detail in Fig. 4. At its lower end, the standard 11 is equipped with an enlarged head 12, in which is formed a polygonal opening 14 adapted to receive the lug 8 of the valve 8. The head 12 is supplied with a depending stop lug'15. This stop lug 15 coacts with the stop lug which is usually and commonly formed upon the casing 6 of the angle cock. At its upper extremity, the standard 11 terminates in a polygonal end 16. The standard 11 above the head 12 is of circular cross section and is journaled in a bearing 17 which, in the present instance is shown as connected with the forward face of the end sill 2 of the car.

A lever 18 is provided, the same having an enlarged-head 19 at its forward end, in which head there is a polygonal opening 20, the contour of which corresponds with the cross section of the end 16 of the standard 11, the lever 18 being superposed upon the upper end of the standard 11 and the end 16 of the standard being received within the opening 20. The head 19 of the lever 18 is provided with an outstanding stop lug 21, corresponding to the stop lug 15 of the standard 11 and having functions which will be set forth hereinafter. At the rear end of the lever 18 is an enlarged head 22, provided with openings 23. The lever 18 extends transversely of the upper face of theend sill 2 and operating members 24:, preferably rods, lie above the end sill. The outer extremities of the operating members 24: terminate in handles 25, located between the ends of the sill 2, the inner or adjacent ends of the operating members 24 being pivotally received in the openings 23. Mounted upon the car 1 and in the present instance secured to the upper face of the end sill2 are slide bearings 26 having elongated openings 27 through which the operating members 24 pass.

In practical operation, the operating member-s24 may be controlled from either side of the car, the operating members actuating the lever 18 and the lever 18 rotating the standard 11, the standard in its turn, rotating the valve 8 of the angle cock. I At this point it may be stated, that, if desired, the side port 10 in the valve 8 may be brought into alinement with the bleed port 7 in the casing 6. In this manner, the train pipe line is cut oil, but the connected cou pling hoses 5 between a pair of cars will be permitted to discharge into the atmosphere, through the bleed port 7 and the side port 10.

Referring particularly to Fig. 2 it will be observed that the operating mechanism is so positioned that it cannot be injured should the draw bar 3 be pulled out. The lever 18 and the operating members 2 1 lie above the end sill 2, and as a consequence, these elements will be protected from injury and will be accessible and visible at all times.

The end 16 of the standard 11 is of the same cross section as the lug 8 of the valve 8, the opening 20 in the lever 18 being of the same size as the opening 14: in the standard 11. As a consequence, the standard 11 may the cock having interengaging elements and the lever and the standard having interengaging elements, the cock-engaging element of the standard and the standard-engaging element of the lever being duplicates to permit an interchangeable mounting of the lever and the standard upon the cock.

2. In an air-brake system, the combination with the angle-cock of the train-pipe line, of a standard mounted on the angle- 1 cock; a lever mounted on the standard; and means for operating the lever from a point to one side of the cook; the standard and the cock having interengaging elements and the lever and the standard having interengaging elements, the coclcengaging element of the standard and the standardengaging element of the lever being duplicates to per- 1 mit an interchangeable mounting of the lever and the standard upon the cook, the lever and the standard each being provided with a stop-lug, the lugs respectively, co

acting with the cock when the lever or the standard is assembled with the cock.

In testimony that I claim the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses.

BENJAMIN W. DAVIS.
