SHOE FOR BRAKE-BEAM SUPPORTS.

Application filed May 15,

To all whom it may concern:

Be it known that I, WILLIAM E. FowLnn, J12, residing at Mount Lebanon, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Shoes for Brake-Beam Supports, of which improvements the following is a specification.

It has been necessary to provide guiding supports supplementary to the usual hangers to ensure such positions of brake beams in order thatthe brake shoes may be properly applied to the wheels regardless of changes in the diameters due to turning down of the wheels. In general, the supplementary supports consist of shoes or carriers, as they are sometimes termed, interposed between some. part of the brake beam and a supporting rail so secured to some part of the truck, usually the spring plank, and extending on bothv sides of the plank under the brake beam, e

The invention described herein relates to an improved'form of shoe adapted to be used as a member of what is known as a four-point type of brake beam support. The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part. of this specification, Fig. 1' is a plan view showing portions of the spring plank of a truck and a truss brake beam and supplenicntal supports embodying the improvements claimed herein; Fig. 2 is a side elevation showing the relative positions of the shoe, supporting rail and tension member of a brake beam; Fig. 3 is a side elevation of a modification of the construction of shoe, and Fig. 4; is aside elevation illustrating a further modification of the shoe as shown in Fig. 3.

In the practice of the invention the support rails 1 are secured to the spring plank 2 in such manner that rails will extend under the brake beam at points intermediate the strut 3 and the ends of the brake beam as shown in Fig. 1. As is usual, the portions of these rails adjacent to their ends are inclined upwardly and on such inclined portions are mounted the shoes which in turn support the brake beams.

The improved shoe consists of a block 4 1924/ Serial No. 713,559.

having a slot or opening 5 therethrough for the reception of the supporting rail, along which the shoe will slide as the brake beam is shifted towards and from the wheel. On

this block is mounted a saddle 6 U-shaped saddle portions should be made integral one,

with the other. This construction will permit of the easy removal of the brake beam from the shoe by a vertical movement of the beam or of the supporting rail and shoe without the employment of tools or the changing of the shape of any portion of the shoes. hen the shoes are constructed as described and as shown in Fig. 2, they must necessarily be made rights and lefts on account of the opposite inclination of the portions of the tension member on opposite sides of the strut. For this reason, it is preferred to construct the shoe in the manner shown in 3. The block 4" which is provided with a slot for the re ception of the supporting rails as above described, has formed on opposite sides thereof, saddles G arranged respectively at opposite angles to the axis of the block and hence the block can be used indiscriminately on one side or the other of the strut. While it is preferred that the block should be so constructed that the sides of the saddle will be at right angles to these supporting rails when the shoes are in position on the rails as shown in Figs. 2 and 3, they may be formed as shown in'Fig. 4, in which case, when the shoes are in position on the rails the sides of the saddle will be at an acute angle to the supporting rail.

I claim herein as my invention:

1. A shoe forbrake beam supports con-- sisting of a base or body slotted for the reception of a supporting rail and provided with an open-topped seat for engagement with a portion of the brake beam.

2. A shoe for a supplemental support of a brake beam consisting of a body portion slotted for the reception of a supporting rail and provided on one side with an openended saddle for the reception of the tension member of a brake beam, said saddle being arranged at an angle to the axis of the body portion corresponding to the angle of the tension member to the rail.

3. A shoe for a supplemental support of a brake heznn (-onsisl'ing ol :1 body portion slotted for the rer-eption of a supporting rail and provided on opposite sides with open-ended saddles for the reception of the tension member of a brake beznn, said saddles being arranged Ht an angle to each 0 other and to the axis of the body portion. In testimony whereof, I have hereuntoset my hand.
