RAILWAY BRAKE-BEAM.

Specification of Letters Patent.

Application filed August 25, 1908.

Patented Oct. 27, 1908.

Serial No. 450,162.

To all whom it may concern:

Be it known that I, SETH A. CRoNn, a on its upper and lower sides with shoulders citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Railway Brake-Beams, of which the following is a specification.

The invention relates to improvements in railway brake-beams, and consists in the novel features hereinafter described, and particularly pointed out in the claims.

My invention pertains to truss-beams and resides more particularly in a novel strut and means for securing the same to the compression member, as hereinafter explained.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a top view of the middle portion of a railway brake beam constructed in accordance with and embodying the invention, and Fig. 2 is a side view of the strut, with the truss rod shown in central transverse section and the compression member in transverse section on the dotted line 2-2 of Fig. 1.

In the drawings, 10 designates the compression member, 11 the truss rod and 12 the strut, the truss rod being of customary character and secured at its ends to the ends of the compression member, as usual in truss beams.

The compression member 10 is formed of a rolled flanged section and is preferably of T-shape in cross-section as shown.

The strut 12 is of cast metal and at one end engages the middle portion or bend of the truss rod in a customary manner, while at its other end said strut engages the compression member and is secured thereto by means of a clip 13 and rivet 1 1. The outer end of the strut 12 is slotted or recessed, as at 15, to receive the web 16 of the compression member 10, and the extreme end surface of the strut is curved, as denoted by dotted lines in Fig. 1, so as to ride against and firmly engage the flange portions of said member 10. The base of the recess 15 in the strut is also curved, as shown by dotted lines in Fig. 1, so as to facilitate any necessary angular movement of the strut to the straight position shown in Fig. 1 in applying it to position between the compression member and truss rod.

17 which are correspondingly inclined so as to afford wedge surfacesfor coaction with the inturned ends or lips 18 of the clip 13, which lips are inclined to correspond with the outlines defined by the shoulders 17.

The clip 13 will preferably be a forging and consists of a bar of about the width of the strut bent to closely encompass, transversely, the flange portion of the compression member and the outer upper and lower side portions of the strut, with the lips or ends 18 of said bar turned inwardly to engage the shoulders 17 on the strut and bind the latter to the compression member.

In applying the strut 12 to the other parts of the beam; the usual end nuts securing the ends of the truss rod may be loosened and the strut introduced between the truss rod and compression member, after which the clip 13 may be applied over the compression member at one side of the strut (to the right of the strut, looking at Fig. 1) and slid along the same toward and onto the end of the strut, the lips 18 of the clip passing upon and finally, with firmness, wedging against the shoulders 17 and binding the clip, strut and compression member to gether. I thereafter to further secure the clip, strut and compression member together and prevent the clip from losing its position during the employment of the brake-beam, apply the rivet 14 transversely through said parts, as shown. In instances where it may not be desired or possible to loosen the ends of the truss rod preparatory to applying the strut to position, I will first place the strut between the compression member and truss rod in an angular position with one end of the strut on the middle bend of said rod and the other end of the strut against the compression member, with the web 16 of the latter in the recess 15, and then force the outer end of the strut along thecompression member until the strut attains its straight position, whereupon I will apply the clip 13 and rivet 14 in the manner hereinbefore explained.

The clip 13 affords a very desirable and efficient means for binding the strut and compression member together, without adding undue weight to the beam or expense to its manufacture. It is desirable also that the outer end of the strut socket against the compression member and seat or rest on a ice horizontal portion of the same, since thereby durability of construction is attained and the weight of the end of the strut is supported by the compression member rather than by the lower side of the clip 13.

hat I claim as my invention and desire to secure by Letters-Patent, is:

1. A brake-beam comprising a compression member, a truss rod and a strut, said compression member being a rolled section and the end of said strut engaging said member and being seated on a horizontal portion of the same and having shoulders on its upper and lower sides, combined With a clip transversely embracing said compression member and having inturned lips en gaging said shoulders; substantially as set forth.

2. A brake-beam comprising a compression member, a truss rod and a strut, said compression member being a rolled section and the end of said strut engaging said member and being seated on a horizontal portion of the same and having shoulders on its upper and lower sides, combined with a clip transversely embracing said compression member and liaving inturned lips engaging said shoulders, said shoulders and lips being inclined so as to wedge together; substantially as set forth.

3. A brake-beam comprising a compression member which is of T-shape in cross section, a truss rodand a strut, the end of the latter being recessed to pass on the web of the compression member and formed With shoulders on its upper and lower sides, combined with a clip transversely embracing said compression member and the end of said strut and having inturned lips engaging said shoulders; substantially as set forth.

4. A brake-beam comprising a compression member which is of T-shape in cross section, a truss rod and a strut, the end of the latter being recessed to pass on the web of the compression member and formed with shoulders on its upper and lower sides, combined with a clip transversely embracing said compression member and the end of said strut and having inturned lips engaging said shoulders, said shoulders and lips being inclined so as to wedge together; substantially as set forth.

5. A brake-beam comprising a compression member which is of T-shape in cross section, a truss rod and a strut, the end of the latter being recessed to pass on the Web of the compression member and formed With shoulders on its upper and lower sides, combined with a clip transversely embracing saidcompression member and the end of said strut and having inturned lips engaging said shoulders, the outer end of said strut being curved to permit angular movement of the strut in applying the same and to enable afirm seating of the end of the strut against the compression member; substantially as set forth.

Signed at New York city, in the county of New York and State of New York, this 24th day of August A. D. 1908.
