OF CHICAGO, ILLINOIS, A CORPORA- REVERSIBLE FULCRUM FOR BRAKE-BEAIVIS.

SPECIFICATION forming part of Letters Patent No. 722,655, dated March 10, 1903.

Application filed February l2, 1902. Serial No. 93,800. (No model.)

To ctZZ whom. it may concern.-

.Be it known that I, CHARLEs H. WILLIAMS, Jr., a citizen of the United States, residing at Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reversible Fulcru ms for Brake-Beams, of which the following is a specication.

This invention relates to a new and useful xo improvement in a reversible fulcrum for brake-beams, being designed particularly for use in connection with various types of what are commonly known as solid beams.

The objects of my invention are to simplify the construction of devices of the character indicated, so as to enable the same to be easily made, quickly applied, and when in position to rigidly hold the fulcrum in place. With these objects in view the invention zo consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings, Figure 1 is a top plan view of my improved reversible ful'crum in position on a beam which is I-shaped in section. Fig. 2 is a vertical sectional View through the same on line 2 2 of Fig. 3. Fig. 3 is a sec. tional view on line 3 3 of Fig. 2. Fig. 4 is a detail view of the clamping-block.

1 indicates the beam, which may be of any usual cross-section, the beam shown in the drawings being I-shaped.

The clamping-block, through the medium of which the fulcrum-block or lever-post is mounted and locked in a rotatably-adj usted position,consists of what I will call top and bottom cross connecting-pieces 2, whose side edges are reinforced byinwardly-extending flanges 3. The rear edges of these cross connecting-pieces, as well as their forward edges, are provided with seats 4 for receiving the flanges of the I-bearn. The rear edges are also bent or anged inwardly to engage the outer face of the I-beam flange, and these top and bottom connecting -pieces also at their outer edges are connected by straps 5, which straps are preferably integral therewith.

The forward edges of the connecting-pieces are reinforced or thickened and are extended inwardly toward -each other outside of the forward ange of the beam, said extensions being provided with semicircular recesses which register with each other when the clamping-block is secured in position to form' a circular opening for the reception of the securing-head on the inner end of the leverpost. As shown, this opening is enlarged at its inner edge to receive the head referred to. 6o

6 indicates lugs or extensions projecting forwardly from the connecting-pieces, preferably beyond the base of the lever-post.

7 indicates the lever-post, which consists of a base portion 8, having a anged head 9 65 extending inwardly from its inner face and designed to be received in the opening above referred to.

lO indicates the jaws of the post, which are provided with openings for the reception of 7o the pivot-bolt of the brake-lever, as is well understood.

The base of the lever-post is notched, as at l1, said notches being arranged so as to be circumferentially displaced with respect to the plane of the brake-lever, usually forty degrees; but the degree of displacement may be any desired.

2 indicates a bolt or rivet which is employed for the purpose of securing the clamp- 8o ing-block `in position on the brake-beam. As this bolt or rivet passes through the web of the beam and through the connecting-pieces, it will be seen that the clamping-block'is absol utelylocked against longitudinal displacement. The extensions at the forward ends of the cross connecting-pieces when the clamping-block is secured in place embrace the head of the lever-post, permitting the same to be rotated so as to bring one of the notches 9o 11 opposite one of the lugs 6. When the parts are in this position, the lug, which registers with the notch, is bent down into the notch, thus locking the lever-post at the desired angle and in the desired position. If occasion requires a change in the position of the lever-post, the bent lug may be broken, the lever-post rotated to its newfposition, and the lug which remains on the clamping-block is now bent into its registering notch to lock 10o the lever-post against rotation. While I have shown these lugs as being on the clampingi block and the notches in the lever-post, it is obvious that the position of these elements may be reversed or that they may be located at other points.

I am aware that many minor changes may be made in the construction and arrangements of the parts of my device without in the least depart-ing from the nature and principle of the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. The combination with a brake-beam, of a clamping-block, means for clamping said block on said beam, a lever-post rotatably mounted in said clamping-block, and means in the form of lugs and notches, for locking said lever-post in an adjusted position; substantially as described.

2. The combination with a brake-beam, of a clamping-block, means for securing said clamping-block on said beam, a lever-post rotatably mounted in said clamping-block, notches in said lever-post, and a plurality of lugs on said clamping-block for coperating with said notches tolock the leverpost againstrotation; substantially as described..

3. The hereindescribed clamping-block consisting of cross connecting-pieces, straps for connecting one end of said connectingpieces, and inwardly-extending projections on the free ends of said connecting-pieces; substantially as described.

4. The herein -described clampingblock consisting of reinforced cross connectingpieces, straps for connecting the rear ends of said cross-pieces, inwardly-extending projections on the free ends of said cross connectingpieces, said projections being formed with registering semicircnlar recesses; substantially as described.

l5. The herein-described clamping-block consisting of cross-pieces connected by straps at their rear ends, inwardly-extending projections on their forward or free ends which are designed to embrace and hold the leverpost in position, and lugs extending forwardlyT from the cross-pieces; substantially as described.

6. The herein-described clamping-block consisting of cross connecting-pieces, means for connecting one end of said cross-pieces, and inwardly-extending projections on the opposite ends of said connecting-pieces forming between them a socket for a swiveled member adapted to be held therein; substantially as described.

- 7. The herein described clampingblock consisting of cross connecting-pieces, integral means for connecting one end of said crosspieces, and inwardly-extending projections on the opposite ends of said connecting-pieces forming between them a socket for a swiveled member adapted. to be held therein; substantially as described.

8. The herein described clampingblock consisting of cross connecting-pieces, in-

wardly-extending flanges on said cross-pieces, means for connecting one end of said crosspieces, and inwardly-extending projections on the opposite ends of said connecting-pieces; substantially as described.
