Specification of lLetters Patent.
Application filed April 19, 1905. Serial No. 256,491.
Patented Dec. 12, 1905.
To all whom it may concern:
Be it known that I, JAMES A. LIGHTBODY, a citizen of the United States, residing at Waterville, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Brake-Lever Supports,
of which the following, taken in connection with the accompanying drawings, is a speciication.
My invention relates to a device for supporting the levers that are pivotally connected to the cross-bar frame or truss that connects the two brake shoes connected at their lower ends to brake-connecting rods and at their upper ends by the chain or rod that serves to operate the brakes; and it consists in attaching to the said cross-bar frame or truss inverted yokes, the upper parts of which serve as rests or supports for the said levers.
This invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan showing one end of a truck-frame. Fig. 2 is a view, on a larger scale, drawn partly in end elevation and partly in section. Fig. 3 is a side view showing a part of the truck-frame, one of the wheels, and one of the brake-levers, its connected parts, and the inverted yoke that supports the lever.
In the drawings parts only of a truck are shown. The parts that do not relate to my device are omitted.
The frame of the truck is indicated by A, the wheel by W W, the axle by B, the rails by R R, and the brake-shoes, two of which are shown in Fig. l, by S and S, one only being shown in Fig. 2. The brake-bar connection, which passes from one brake-shoe to the other, is a truss-frame consisting of a main bar S/ and inclined truss bars T T, connected in the center to the coupling-piece T, which may be a part ofthe housing-piece H H, through a slot in which the brake-lever L passes. The said brake-lever L is pivoted at H2 (see Fig. 3) in the usual manner.
As the brake device is usually constructed the lever L has no support above the housing-block I-I and soon Works loose, Wears badly, and is liable to soon get out of good working order. To remedy this defect, I have constructed the yokepiece P P2 P and attached it to the members S and T of the brake-bar truss by clamps, as shown. The upper part P2 of the yoke forms a rest or support for the brake-lever L.
I claim- A brake-lever support comprising an inverted yoke-piece attached to the brake-bar truss and constructed to support the brakelever, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, on this 11th day of April, A. D. 1905.
JAMES A. LIGHTBODY.
