MEANS FOR OPERATING TRAIN-PIPE AIR-BRAKE VALVES.

To all whom it may concern:

lie it known that I, AXnL G. OLSON, a citizen of the United States, residing at Two Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Means for Operating Train-Pipe Air-Brake Valves, of which the following is a specification, reference being bad therein to the accompanying drawing.

Ny invention relates to improvements in means for operating train pipe air-brake valves.

The object of my invention is to provide means whereby the airbrake valve arranged between the cars may be readily opened or closed from the far side without the operator passing between the cars.

A still further object of my invention is to provide a simple, cheap and more effective means to accomplish the above result and having certain details of structure hereinafter more fully described.

In the accompanying drawings: Figure 1 is an end elevation of a railway car showing my improved operating rod in a position out of engagement with the valve lever of the air-brake or retainer valve. Fig. 2 is an enlarged perspective view of the valve and operating rod clearly illustrating their relation to each other.

Referring now to the drawings, 1 represents a car and 2 the air-brake valve positioned as in the usual way upon the end of the car and to one side of the center thereof, whereby it is readily accessible from one side of the car. Carried by the valve 2 is a valve lever 3, by which the valve is operated and which is designed to remain in any position set for the retention of the air-pressure upon the air-brake, all of which is well understood to those skilled in the art.

Carried by the end of the car and spaced a distance apart are staples or ears 9 and 9 in which is rigidly supported a pipe 5, which is of such a length that it does not extend all the way to the valve lever 3. This pipe, as heretofore stated, is rigidly supported in the ears or staples 9 and 9 and loosely passing therethrough is an operating rod 4, which is of a length greater than that of the pipe 5. The inner end of the rod 4, adjacent the valve lever is turned laterally at (3 and then outwardly at 7 substantially atright angles to the lateral portion 6, but parallel with the body of the rod, as clearly Specification of Letters Patent.

shown in Fig. 1 of the drawings and forming a crank for engaging the lever 3 and operating the same.

The opposite end of the rod 4, is turned laterally at right angles to the body portion, as indicated at 8, forming a crank-arm, whereby the rod may be readily oscillated within the pipe '5. It will be observed that the pipe 5 is suiticiently shorter than the distance between the cranks 6 and 8 to admit of the rod being moved longitudinally within the pipe to allow the crank 7 to be moved inwardly to engage either side of the valve lever 3, and thus operating it in either direction, and at the same time allowing it to be drawn outwardly so that the accidental oscillation of the rod 4 will not operate the valve lever 3 when not in use, as clearly shown in Fig. 1 of the drawing.

From the description herein given, it will be readily seen that if the portion 7 of the rod 4 is on one side of the valve lever 3 to operate the valve in one direction, to open the valve, and it the valve has been opened and it is desired to close the valve, all that is necessary is to move the rod 4:, longitudinally within the pipe 5, and slightly oscillate the rod so that the portion 7 will be on the opposite side of the valve lever. The slight oscillation of the rod 4 will then move the valve lever 3 in the opposite direction to close the valve. Vhile T have shown this form of mounting the rod l, it is evident that the pipe could be readily dispensed with and the ears or staples 9 could be placed in such a position adjacent the ends cf the rod to limit the longitudinal adjustment of the rod, accomplishing the same re sult as the pipe 3. Pins or set-screws in collars upon the rod might be used to accomplish the same result as the pipe 5, or ears or staples 9 and 9.

The particular advantage of this invention is that of providing means whereby the retainer valve may be operated from the far side of the car without the necessity of the operator going in between the car and thus endangering his life.

Having thus described my invention,what I claim and desire to secure by Letters Patent is:

1. The combination with a railway car having an air-brake valve at one end, a

downwardly extending lever carried by the valve, an oscillating longitudinally movable rod supported at the end of the car and having a crank adapted to engage either side of the said valve arm and means where by said rod may be moved longitudinally and oscillated.

2. The combination with a railway car having an air-brake valve at one end adjacent one side, a downwardly extending valve arm carried by the valve, a longitudinally movable oscillating rod carried by the end of the car and having a late ally turned end provided with an outwardly extending portion parallel. with the boc y portion of the rod and adapted to be brought into engagement with either side of the valve lever, and a crank carried by the opposite end of the rod for operating the same.

The combination with a railway car having an air-brake valve located at one end adjacent one side, a downwardly eX- tending valve lever carried by the valve, a longitudinally movable oscillating rod carried by the end of the car, means for lin1it ing the longitudinal. movement of the said rod. a laterally extending port-ion carried by the inner end of the rod and having an inwardly turned portion parallel to the body of the rod and adapted to be moved into engagement with either side of the valve arm, and a crank carried by the opposite end of the rod adjacent the opposite side of the car, whereby the valve lever may be moved in either direction for opening or closing the valve.

4. The combination with a railway car having an air-brake'valve at one end adjacent one side, a downwardly extending valve lever carried by the valve, horizontally arranged supports carried by the end of the car, a pipe rigidly supported in said supports, a rod extending through said pipe and having at its inner end a laterally turned portion provided with an inwardly turned end. adapted to engage either side of the valve lever, the opposite end of the rod having a crank arm and said rod being of a length greater than that of the pipe whereby it may be moved longitudinally therein to bring the inwardly turned portion of the crank in engagement with either side of the valve lever.

in testimony whereof I hereunto affix my signature in the presence of two witnesses.
