Shoes, of which the following is a specification.
This invention relates to brake shoes and it consists in the novel features hereinafter described and claimed.
An object of the invention is to provide a brake shoe of simple and durable structureadopted to be applied to the driving wheels of a locomotive or the wheels of a car truck the shoe being of such a structure as to frictionally engage the wheels and also to trictionally engage the track rail whereby the wheel is prevented from slipping upon the rail when the brake shoe is applied, thus protectin the tire of the wheel against wear.
With tnis object in view the invention includes in combination with a block having a groove disposed transversely across its .lge a brake shoe of at length sufiicientto extend from the said block to the track rail when the brake is applied. The shoe is provided with a rib which fits in the said groove and is provided with flange at its upper end which engages the upper end of the said block. The shoe is provided at its lower portion and at its opposite sides with lugs adapted to receive the track rail between them. whereby the lower portion of the shoe is held in proper position with relation to the rail'when the shoe is applied to the periphery ot' the-,wheeL In the accompanying drawing:
Figure 1 is a side elevation. of the brake shoe showing the same applied to a block and its relative position with rela ion to a wheel and track rail.
Fig. 9 is a vertical sectional view through the brake-shoe.
Fig. 3 is an under plan view of an end portion ofthe shoe.
Fig. is a transverse sectional view through the track rail out on the line 4.4 of Fig 2, v
As illustrated in the accompanying drawing the block 1 is provided at its rear, side with a transversely disposed groove 2, and
the said block is attached to a brake link 3' and beam 4: in the usual menner.
The broke shoe 5 is provided at its upper forward portion with s rib 6 which fits snugly in the groove 2 and the said shoe is provided at its upper end with a flange 7 which engages over the upper end of the block 1. A bolt 8 passes transversely through the shoe and the intermediate por- Lion of the block 1 and serves as a means for holding the said shoe in position upon the block. The shoe 5 is of a length siulicient to extend from the block 1 to the track rail 9 when the shoe is applied to the periphery of the wheel 10. The shoe 5 is provided at its lower end and at its opposite edges with lugs ll which are adapted to receive the head of the track rail between them who the shoe is applied to'the periphery of the wheel 10. The lug ll at the inner side of the track rail 9 is a little shorter than the lug 11 at the outer side thus providing sulflicient space or room for receiving the flange of the wheel 10.
When the block 1 is moved so that the shoe 5 is applied to the periphery oi the wheel 10, the said shoe frictionally engages the wheel and the lower portion of the s we ext-ends under the wheel and bears tjficetly' against the upper surface of the head of the track rail'9 whereby the said wheel is lifted from the track rail and the shoe is interposed between the wheel and track rail. During this movement of the shoe, the lugs 11 direct the lower portion of the shoe under the wheels and prevent the shoe from mov ing ltiterally from between the wheel and. track rail. Con, equently it will be seen that when the shoe is applied, the wheel is lifted from the rail and the shoe frictionally engages the rail thus relieving the tire of the wheel froi'n wear a nd preventing the same from becon'iing' flattened as is the case in usual construction when brake shoe is applied to the wheel with suilicient force to bring the wheel to a state of rest while it slides along the track rail.
Having described the invention What is claimed is:- a
1. in combination with a block having a, transversely disposed groove, a brake shoe having a rib adapted. to be received by the groove and provided'with a flange adapted to engage over the end of the block, said shoe being of a length sufficient to extend from the block to the traei: rail when the shoe is applied the shoe being provided at its lower portion and at opposite sides with spaced lugs.
v 2. In combination with at block having a transversely disposed groove, a brake shoe portion and at its opposite si des with lugs having 21 rib adapted to enter the groove adapted to he at the opposite sides of the and provided with a flange adapted to enhead of the track mil, the lug at the inner 19 gage over the end of the block, the shoe heside of the rail being shorter than the lug ing of a length sufhoieni to extend from the at the outer side. block to the track rail when. the shoe is 2119- in testimony whereof I affiX my signature. plied, the shoe being p 'oviderl at its lower WILLIAM G. L. TOTTEN.
