RAILWAY BRAIKE-BEAM.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed August 5, 1908. Serial N 0. 447,022.

T 0 all whom it may concern:

Be it known that I, SETH A. OnoNE, a 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 isa specification.

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

The object of my invention is, more p articularly, to provide an improved and highly eflicient compression member for trussed brakebeams, and more especially to construct said member from a structural beam section, preferably ofT-shape in cross-section, in such manner that at its end'portions it will form recesses for the end portions of the truss-rod, receive the bearing-sleeves for the brakeheads and afford m Ximum strength to resist the power applied against said end portions in service.

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

Figure 1 is an elevation of one end portion of a trussed brake-beam, with the bearingsleeve thereon for the brake-head, not shown Fig. 2 is a like view of one end portion of the compression member of the beam, the truss rod and bearing sleeve being omitted; Fig. 3 is a transverse section through the compression member and truss rod of the beam on the dotted line 3-3 of Fig. 1; Fig. 4 is a like section through the beam on the dotted line 4-4 of Fig. 1 Fig. 5 is a like section through the beam on the dotted line 5-5 of Fig. 1; Fig. 6 is a like section through the same on the dotted line 6-6 of Fig. 1, and Fig. 7 is a section through a modified form of the compression member on the line of the section of Fig. 4, this modification consisting in upsetting the web of the beam in lieu of splitting it to straddle the truss-rod-in the manner shown in Fig. 4.

In the drawings, 10 designates the compression member, 11 the truss-rod, and 12 the sleeve securing the corresponding ends of said compression member and rod together and adapted to receive, in a well understood manner, the brake-head, not shown.

The truss-rod 11 is commonly used in trussed brake-beams and requires no detailed description; it is customarily threaded at its ends to receive securing nuts 13 which bind against the outer oblique ends of the sleeves 12.

The compression member 10 is preferably made from a rolled commercial beam of T- shape in cross-section, and in the production of the member 10 therefrom I do not neces sarily modify the beam section except at its end portions, which I do reconstruct in respect to the web 14 and flange 15.

My invention resides, therefore, in a novel construction of the end portions of the brake-beam, and in carrying out one form of my invention I split the web 14 to create lips 16 (Fig. 4) which receive between them portions of the rod 11, "and outwardly beyond the lips 16 I compress the web 14 and flange 15 into a solid end 17, which outwardly be yond the lips 16 is recessed, as at 18, to continue the recess for the truss-rod 11. In the formation of the solid ends 17 I preserve the general longitudinal plane of the outer central line of the flange 15, as denoted in Fi s. 1 and 2, and crowd the side portions of t e flange 15 in a direction toward the web 14 and press the web in line with its edge in a direction toward the middle of said flange, whereby a solid integral end 17 is produced which has a straight outer edge, diverging sides and a concave inclined inner surface 18, said end decreasing in thickness from about the outer ends of the lips 16 to the outer end of the beam, as shown by the relative thicknesses of metal in the end 17 represented in Figs. 5 and 6.

My purpose is to produce solid ends 17 at the end portions of a rolled flanged commercial section and to maintain in said ends the maximum amount of metal disposed to secure the greatest amount of strength and efliciency. I therefore seek to avoid cutting away portions of the beam in creating the compressed ends 17 but find that in the use of some rolled sections it is necessary to clip ofi a portion of the outer end of the web 14, outwardly beyond that part used in forming the lips 16, prior to the compression of said ends so that I may not have too much metal to be conveniently confined within the sleeve 12, whose diameter is limited to the requirements of standard brake-heads. The li s 16 are formed to preserve or leave in the earn the maximum quantity of metal at the inclined end portions of the rod 11 rather than to afford seats or recesses for said rod, and in lieu of forming the lips 16 the may be left in the beam by upsetting the web thereof in the manner shown in Fig. 7, said web being upset in a direction toward the flange of the beam and thereby thickened in affording space for the inclined end portions of the rod 1.1.

In both the constructions shown inlTigs. 4 and 7, the metal of the web is displaced to allow the rod 11, at its ends, to take the proper angular relation to the beam, so that the n'iaximum strength. may be secured in the beam. acter with the exception that its interior socket conforms to the new shape of the end 17.

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

1. In a brake-beam, a rolled flanged compression member having, at each end, the web and side portions of the flange, compressed into a solid integral end forming a recess for the end of the truss-rod; substan tially as set forth.

2. Ina brakebeam, a rolled flanged compression member having, at each end, the web and side portions of the flange compressed into a solid integral end having diverging sides and a concave recess between said sides for the truss-rod; substantially as set forth.

3. In a brake-beam, a rolled flanged compression member having, at each end, the web and side portions of the flange com pressed into a solid integral end. forming a re cess for the end of the truss-rod, and the Web of said member inwardly from said ends same metal l The sleeve 12 is of customary charbeing displaced to allow the ends of the rod to have their proper inclination; substantially as set forth.

4. In a brake-beam, a rolled flanged compression member having, at each end, the web and side portions of the flange com pressed into a solid integral end having diverging sides and a concave recess between said sides for the truss-rod, and the web of said member inwardly from said ends being displaced to allow the ends of the rod to have their proper inclination; substantially as set forth.

5. In a brake-beam, a rolled flanged compression member having, at each end, a portion of the web split and. spread open to receive the truss-rod, and beyond the same having the web and side portions of the flange compressed into a solid integral end forming a recess for the outer portion of the truss-rod; substantially as set forth.

6. In .a brake-beam, a rolled flanged compression member having,'at each end, a portion of the web split and spread open to receive the truss-rod, and beyond the same having the web and side portions of the flange compressed into a solid integral end having diverging sides and a concave recess between said sides for the truss-rod; substantially as set forth.
