BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 289,313, dated November 27, 1883. Application filed June 20, 1583. (No model.)

To ctZZ whom it may cancer/2,.-

Beit known that I, GUSTAVUS B. Snuonns, of Sedalia, in the county of Pettis and State of Missouri, have invented a certain new and 5 useful Improvement in BrakeShoes and Heads, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which-- to Figure 1 is a perspective view of the shoe and head, and Figs. 2 and 3 aresimilar views of the two parts detached.

cal longitudinal section of the head, the shoe being shown in side view, taken on line 4 4, Fig.

6 is a transverse section taken on line 6 6, Fig.

4. Fig. 7 is a perspective view of thelockingblock removed, and Fig. 8 is a similar view of a device for holding the block down and for raising it up when desired. My invention relates to the construction of the head and shoe and the manner of holding the latter to the former, whereby it can be easily and quickly removed and replaced.

My invention consists in points of novelty, hereinafter fully described and claimed.

Referring to the drawings, A represents the brake-beam, to whichthe head B is secured by a bolt, O, or other suitable means. D represents the customary hanger, suspended from the bottom of the car or truck for the purpose of supporting the brake shoefand head.

E represents the shoe, which has two lugs, E, 011 its back, both of whichzhave downturned ends. (See Fig. 4.) The headhas two openings or recesses, B B, in its face, to receive the lugs E E on the shoe, and at the inner part of these openings B B are verti- See Fig. 4.) The openings or slots B B are to the rear of cross-bars B B, beneath the openings B 13*. F represents a locking-block, which hits and has vertical movement in an opening or recess, G, in the head. As a means ot' holding the block in its lower position and for raising it when desired, I have shown a spring-catch consisting of two pieces, H H,

" which are secured to the block by theirlower Fig. 4 is a vertical openings or slots B B, which receive the. l downturned ends of the lugs on the shoe.

ends, (see Figs. 4, 7, and 8,) and whose upper ends extend out through an opening or slot, I,

in the top of the head. The part H of the catch has a shoulder, H, which engages with the head when the block is in its lower position, (see Fig. 4,) and by pulling or forcing this part of the catch back the block can be raised.

The recess D in theliead, in which the lower end of the hanger fits, is of oblong shape, as shown in Figs. 1 and 3, so that the hanger can be moved therein.

To secure the shoe to the head, the block F is first raised and the hanger moved back into the position shown by dotted lines, Fig. 4, 6 5 which allows the lugs E E on the shoe to enter the recesses B B in the head, and after they are fully inserted the shoeis lowered, the downturned ends of the lugs entering the vertical recesses or slots B" B, as shown in Fig. 4, and the hanger is then moved forward over the lug E and the block dropped to its lower position, holding the hanger in its forward position over the lug. The upper corner of the lug E may be cut off, as shown at J, Figs. 2 and 4, to allow the hanger to be more easily engaged over the lug. The brake-shoe can thus be quickly and conveniently secured to the head, and can be removed by simply raising the block F, moving the hanger back from over the lug, and raising and moving the shoe outward to disengage the lugs from the sockets. The block F is inserted through the hole or recess B into its place.

A ring or pin or other device may be used in place of the hanger to hold the shoein place on the head.

Instead of the lifting-arm of the block eX= tending up through the top of the head, it may extend out through a slot, D in the back, as shown at H in Figs. 1 and 4. WVhere one is used the other would .not be required, and where the latter is used some means other than the spring-catch described would be used to hold the block down.

The lugs on the shoe may have upturned instead of downturned ends, and the openings in the head would be formedaccordingly.

I claim as my invention- 1.. The combination of abrake-head having 100 a slot, D, a hanger occupying said slot to lock H and occupying the recess and slot D to the shoe to'the head, and means for holding hold the hanger in position to lock the shoe to the hanger in locked position, as set forth. the head, as set forth.

2. Ihe combination of abrake-head having 4.
