BRAKE-HEAD.

Specification of Letters Patent.

Application filed June 16, 1909. Serial No. 502,587.

To all whom it may concern:

Be it known that I, ALBERT WAYCOTT, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Brake-Heads, of which the following is a specification.

The present invention relates to brake.

heads and has'for its object the provision of such a means of the forged type, as distinct from a casting, wherein the same is adapted to be secured to the. brake beam in a continu-' ous and united piece surrounding the latter, and wherein the brake head offers a resilient and compensating medium to the brake shoe proper.

The structure of the several parts and their peculiar manner of assembling is such that the brake head may be readily fitted to the brakebeam, and when in applied position offers, a suitable resistanceto excessive wearing byfriction which fault constitutes the main disadvantage of the present used brake heads of this general type.

The invention is designed as a further improvement over Patent No. 906,708, granted December 15, 1908, for improvements in brake heads of the kind in question, invented byv Philip T. Handiges, and assigned to the Damascus Brake Beam Company, of Cleveland, Ohio. -,The further advantages of the invention will be made clear in the course 'of the following extended description and the points of novelty therein set forth in the claims.

In the accompanying drawings, Figure l is a side elevation of the brake head 1n applied position, Fig. 2 is a vertical section of the same, illustrating the i'nanner of securing the brake shoe thereto, Fig. 3 is a front elevation, Fig. l is a top plan view thereof, Fig. :3 illustrates the brake head in blank and punched ready for bending, Fig. 6 illustrates the blank after the first operation for forming the same inthe bending dies, and, Fig. 7 illustrates the same after-the second operation.

Referring to the drawings in further detail and wherein like nl'unerals of reference indicate corresponding parts in the (litterent views shown, 1 is the tension member of .a. trussed brake beam, which member is constructed of T angle-iron, and 2 the compression member, which, for its greater length, is of substantially V shape in cross section but at its point 3 of union or intimate contact with the bar 1 is depressed to a U-section by which it clamps against the web of the T bar 1.

The end of the T-bar is cut away on opposite sides as shown at 4 in Figs. 1 and 2 and the. reduced portion 5 thereof is turned Patented Dec 28, 1909.

at right angles and lies in intimate contact with the end of the web of the T-bar 1, in which position said reduced portion acts as a head or abutment plate for the ends of the U portions 3 of the truss bar 2.

The brake head comprises a blank plate 6 which after having gone through the several necessary operations inthebending dies, wherein it receives successively the shapes indicated by Figs. 6 and 7, and finally the form shown in Figs. 1 and 2.

Thus constructed the head is bent upon; itself to provide the bow portion '7 .which affords apart of the resilient medium thereof, the intermediate portionFS providing a resilient abutment or front socket wall which lies against the head of the brake beam 1; and to either side thereof and projecting forwardly are the retaining members 9 for the brake shoe. The upper and lower-opposed folded portions 10 and 11 respectively lie in intimate contact with the extreme rear face of the brakeshoe 12. The

means for securing said brake shoe to'the' brake head comprises the wedge pin or key 13 which passes through the several perforations lei and 15 provided in. the brake head. The brake head thus far described is substantially identical in design and manner of securing the brake shoe thereto with that shown and described in the patent above referred to, and 7201' so, does not constitute part of the present invention.

The present lnventlon consists in so constructing such a brake head that it will -form a complete socket embracln the end of the brake beam; this being effected by suitably uniting the ends of the blank where they meet, andcthe advantage of such a construction arising from the firm embrace of the end of the beam by a resilient socket that absorbs vibrations and reduces to a of realizing this condition is as follows:

During the process by which the blank 6 is iven its form the opposite ends thereof are ent as at 16 and the edges thereof are beveled so that said ends 16 may be made to abut as shown, and then the edges are welded as at 17. When applying the brake heads to the T beam said heads are forced over the end of the beam, and the rivets 18 are then introduced 'through perforations formed in'the, brake head, the web of the member 1 and the U-portions 30f the com pression member 2, said rivets being then upset. This fitting of the brake head is rendered more secureby reason of the curved ends 16 thereof lying in intimate contact with the U-portion 3 of the truss bar which is further @fiective to the extent that it minimizes the tendency to relative movement between the part 8 and its contacting face of the cross beam 1.'

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent, is

1. A forged brake head formed of an integral' plate of metal, said plate being bent upon itself to form brake shoe engaging means, and the ends of said plate bein united to 'rovide a securing means for sai brake head '2. A forged brake head formed of an integral plate of metal, said plate being bent upon itself to form brake shoe engaging means, and the ends of said plate being welded to provide a securing means for said brake head.

3. A forged brake head formed of an integral plate of metal, said plate being bent .upon itself to form brake shoe engaging means, and the ends of said plate being bent and having its edges beveled and welded in a flush joint to provide securing means for said head.

4. The combination with a brake beam havin a truss bar, of a forged brake head there or, said brake head formed of an in tegral plate of metal bent upon itself to form brake shoe engagin means, the ends of said plate being unite and surrounding said beam and constituting a securing means for said head. 7 v

5. The combination with a brake beam comprising a bar having an abutment member, and a truss bar abutting against said member; of a forged brake head therefor formed of an integral plate of metal bent upon itself to form brake shoc enga iug means, the ends of said plate being weTdod and overlying the truss bar, and bolts passing through the truss bar, the beam and the brake head.

6. The combination with a brake beam comprisin a T angle bar having an abutment mom or at its ends, and an angle iron truss bar overlying the web portion of the end of said T angle bar and abutting a ainst the abutment member thereof; of a orged brake head therefor, said brake head formed of an inte al plate of metal bent upon itself to form'% i'ake shoe en aging means, the ends of said plate being out and the edges thereof beveled and welded, said end por-- tions adapted to overlie the brake' beam, 75 and bolts passing through said end portions and the brake beam.

7. A forged brake head formed of an integral plate, of metal bent to provide an intermedlate abutting portion, shoe-receiving end portion, and a closed rear socket-portion positioned relatively to the intermediate abutting portion to form therewith a closed socket, adapted to-.surround the end of a brake 'beam.

8. A for ed brake head comprising a plate of metal having its intermediate ortion formed into an abutting bearing fhr the brake beam, extending thence to provide 'arcuate shoe-receivin ends, bent thence upon itself and extending to the middle and having its ends there united and formed into a rear socket ortion positioned relatively to the intermediate portion to form therewith a closed socket adapted to surround the end of the brake beam.

9. In combination with a trussed brake beam having a tension-member of T-section with a forwardly presented bearing face, and a compression member having its end folded upon the web of said.
