BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent No. 791,739, dated June 6, 1905. Application filed December 5, I904. Serial No. 235,655.

To all whom it may concern:

Be it known that 1, CHARLES H. WILLIAMs, J r., a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Brake-Beams, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings,

forming part of this specification, in which.

Figure 1 is a side elevational view. Fig. 2

is a front elevational view, and Fig. 3 is a sectional view on the line 3 3 of Fig. 1.

This invention relates to a new and useful improvement in brake-beams, the object'being to enable the head to be readily and quickly removed in making repairs without necessitating the unhanging of the beam or the disturbance of the integrity of the truss.

With this object in view the invention consists in the construction, arrangement, and combination of the several parts, all as will be hereinafter described and afterward pointed out in the claims.

In service the brake-shoes, which are carried by the brake-head, being secured in poshould be worn, as it is the intention to renew the shoes at frequent intervals, soas to protect the heads; However, when the shoes are ground off and the heads come in direct contact with the wheels it is necessary to renew the heads as well as the shoes, and the principal object of my present invention is to provide a removable brake-head carrying a removable shoe, so that when the brake-head is worn by contact with the wheel, so that it no longer affords a proper. support for the brake-shoe, the head may be removed and a new head substituted.

'- A well-known type of trussed brake-beam is shown in the accompanying drawings, in which the thrust-block is provided with a socket to receive a key on the back of the head. In this manner when it is desired to renew the head it is obvious that the head can be removed from the thrust-block without in the least destroying the integrity of the truss.

In the drawings, 1 indicates the compression member of appropriate character, and 2 I the tension-rod.

3 indicates a thrust-block in which the end of the compression member is seated and through which the tension-rod passes, the latter having a nut 4 on its end for tighteningthe same and placing a camber in the compression member. The front face of this thrust-block is provided with a tapered dovetail recess 5, (the widest portion being at the top,) in which fits a locking-wedge 6 on the back of the brake-head 7. The lower portion of wedge 6 isprovidedwith an opening in which is received a flat cotter-pin 8, which prevents the wedge from rising in its socket.

To remove the brake-head, it is only necessary to knock out the cotter-pin and lift the head until the locking-wedge is released from its seat. I

I amaware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. In a trussed brake-beam, the combination with a thrust-block having a verticallydisposed socket, a removable brake-head, a projection on said head interlocking with said socket, and a renewable brake-shoe carried by said head; substantially as described.

2. In a brake-beam, the combination with 4. The herein-described brakehead, the same havingalocking-wedge on its back, and perforated lugs on its face; substantially as 15 described.

In testimony whereof I hereunto afiix my signature, in the presence of two witnesses, this 2d day of December, 190

CHARLES H. WILLIAMS, JR.
