Specification of Letters Patent.

Application filed April 28, 1915. Serial No. 24,499.

To all whom it may concern:

Be it known that 1, PAUL L. YnAcnR, a

citizen of the United States residing at Roaring Creek, in the county of Columbia and State of. Pennsylvania, have invented new and useful Improvements in Brake-Shoe Holders, of which the following is a specification.

This invention relates to brake shoe holders and more particularly to shoe holders for wagons and other similar vehicles.

The principal object of the invention is to provide a simple and efficient device of this character which will hold the brake shoe against displacement either longitudinally or laterally of the brake block and by which the shoe may be readily-replaced when worn and which obviates the use of nails, screws and other fastening devices.

Another bj ect of the invention is the provision of a device of this character having means for conveniently holding the brake shoe upon the brake block so that it can be removed and replaced without the use of tools.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawin which forms a part of this application, and in which Figure l is an elevation of one end of a brake beam showing my improved type of shoe holder carried thereby. Fig. 2 is a top plan view. Fig. 3 is a detail horizontal sectional view taken on the line 33 of Fig. 1.

Referring more particularly to the drawing, 1 represents an ordinary brake beam to V which is secured the usual type of brake block 2. This brake block has secured to its face adjacent the outer side thereof an angular shoe retaining plate 3 provided with cor ner pieces or end flanges 4: to prevent longitudinal or vertical movement of the block 5. A similar angular plate 6 is slidably mounted upon the block and is also provided with corner pieces or end flanges 7 corresponding to the parts i on the plate 3. This plate has its inner flange transversely slotted as shown at 8 to receive the headed studs 9 projecting outwardly from the brake block 2. These studs guide the plate 6 in its movement toward and away from the plate 3, as will be readily understood.

In order to actuate the plate 6 toward and away from the plate 3 and to firmly hold I to the under face of the brake beam 1 a bell crank lever 10, one end of which is connected directly with the plate 6 through a link 11. The opposite end of the bell crank lever travels over a rack segment 12 as shown. This lever is preferably constructed of some material having sufficient resiliency so that when properly engaged with the teeth of the rack segment a constant pressure will be exerted to force the plate 6 into engagement with the brake block, this pressure serving also to maintain the engagement of the bell crank lever with the teeth of the rack segment.

In order to prevent the shoe from dropping out of the hole when released from the wheel and to accommodate shoes of varying thicknesses there is secured to the'pl'ates 3 and 6 the outwardly extending threaded studs 13 which are engaged within slots 14 formed in the lateral ear or lug 15 formed on the retaining plates or flange members 16. These flange members are independent of the plates 3 and 6 and are held in adjusted position by means of th clampin nuts carried upon the studs 13. By springing thebell crank lever away from the rack segment and pulling its free end rearwardly the shoe clamping plate 6 will be drawn away from the plate 3 and the shoe may be readily removed. A reverse movement of the bell crank lever causes relative approach of the clamping plates 3 and 6, thus clamping the shoe between the same, as will be readily understood.

What is claimed is 1. The combination with a brake block, of relatively movable clamping members carried thereby, means for adjusting one of the members and holding the same in adjusted position and comprising in part a spring lever and adjustable shoe retaining mem bers carried by the clamping members.

2. The combination with a brake block,

relatively movable shoe clamping members carried thereby, means for preventing vertical movement of the shoe within the clamping members, adjustable means for preventing lateral displacement of the shoe, and means for adjusting one of the clamping members toward and away from the other clamping member and comprising a link and a pivoted spring bell crank lever, together with a rack segment for holding the lever in adjusted position.
