DEVICE FOR AUTOMATICALLY SETTING TRAIN BRAKES Filed May 1929 TW W JanwsMJweem W Gum/new).
Patented July 9, 1929. 7
UNITED STATES JAMES M. SWEENEY, OF LEWIS RUN, PENNSYLVANIA.
DEVICE FOR AUTOMATICALLY SETTING TRAIN BRAKES;
Application filed May 6, 1929. Serial No. 360,787.
This invention relates to railway rolling stock, and aims to provide novel means for automatically setting the brakes forming a part of the air brake system of railway rolling stock, so that damage to the railway property caused by falling brake beams, will be eliminated.
An important object of the invention is to provide a. valve located in the train pipe line, which valve will be automatically operated by the weight of a falling brake beam, to release the air in the train pipe line and set the brakes.
Another object of the invention is to provide a device of this character which may be readily and easily installed on the trucks of railway rolling stock, without the necessity of making extensive alterations in the construction of the truck to apply the device.
Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure 1 is a fragmental plan view illustrating a device constructed in accordance with the invention as installed on a truck of a car or the like.
Figure 2 is a side elevational view thereof.
Figure 3 is a detail view of one of the pipe supporting brackets.
Referring to the drawing in detail, the reference character 5 designates atruck bolster, which is constructed of channel bar material, the free edges of the flanges of the channel bar material accommodating the brackets 6. Each of these brackets includes a length of substantially wide metal material, one end thereof being bent downwardly as at 7, to fit with an opening 9 through which the pipe 10 of the train pipe line passes, there being provided a valve 11, fitted on the portion of the pipe 10 that extends above the laterally extended portion 8 of the bracket. The reference character 12 designates an arm that connects with the valve, and as shown this arm extends laterally in the path of travel of the arm 13 which is carried by the brake beam, which in the present showing is indicated by the reference character 14.
A clamp indicated by the reference character 15 clamps the arm 13 to the brake beam 14 with the result that as the beam 14 falls downwardly due to a broken supporting link or chain, the weight of the brake beam will act to rotate the arm 12 operating the valve to release the air in the air pipe line, causing the brakes which are usually held in their inactive positions by the air pressure in the pipe line, to be set, stopping the train and avoiding accident due to the broken brake beam dragging over the track.
I claim:
A pipe connected in the pipe line of the air brake system of a railway rolling stock, brackets positioned over the truck bolster and having lateral extensions, for supporting the pipe, a valve for controlling the passage of air from the pipe to the atmosphere, and means for operating the valve to release air in the pipe when the brake beam of the rolling stock falls downwardly.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
JAMES M. SWEENEY.
