SPECIFICATION forming part of Letters Patent No. 744,722, dated November 24, 1903.

Application filed July 21. 1903. Serial No. 166,455- (No model.)

To all whom it may concern:

Be it known that I, SETH A. CRONE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Brake- Beams for Railway-Oars, of which the following is a specification.

The invention relates to improvements in brake-beams for railway-cars; and it consists "in the novel features and combinations of prising two truss-rods, preferably arranged at I an angle to each other; and the purpose of my invention is to increase the strength and efficiency of metallic brake-beams and more especially to afford in a brake-beam more efficient means for resisting the strains exerted by the brake-lever and preventing the upward buckling or bending of the bodvbeam member at its middle portion.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure l is a top view of a brake-beam constructed in accordance'with and embodying Fig. 2 is an enlarged end my invention. view of same. Fig. 3 is an enlarged edge View looking in the direction of the arrow 3 of Fig. 1 of the strut. Fig. 4 is an enlarged end View showing a modified form of the brake-beam. Fig. 5 is a top view of a further modified form of brake-beam'embracing the invention. Fig.6 is a side view of same looking in the direction of the arrow 6 of Fig. 5; and Fig. 7 is an end view, partly broken away, of same looking in the direction of the arrow 7 of Fig. 5.

In the drawings, 10 designates thebodybeam; 11, the brake-shoe heads; 12, the brakeshoes applied to said heads; 13, the central strut to receive the brake-lever; 14, one of the truss-rods, and 15 the other truss-rod.

The body-beam 10 is of rolled metal and may be of any suitable form, and in the present instance I illustrate as thepreferredconstrnction the beam 10 as being a doubleflanged or I-beam set on edgethat is, with its web vertically disposed and its flanges horizontally extended.

The brake-shoe heads 11 may be of any suitable form and construction adapted to the ends of the beam 10 and to receive suitable 6 brake-shoes 12, my present invention not being confined to anyspecial form and construction of brake-shoe heads and brake-shoes.

The strut 13 is formed with the usual angularly-disposed slot 16, between whose side walls will be mounted in the usual manner the brake-lever, (not shown,)-said walls being provided with the aperture 17 to receive the bolt or pin for said lever. One end of the strut 13 is formed with the. head 18 to pass upon the body-beam 10, and the other end of said strut, referring to Figs. 1, 2, and 3, is formed with a central recess 19 toreceive the middle portion of the truss-rod 14 and with a bearing-recess 20 to receive the middle portion of the auxiliary truss-rod 15, the said' bearing-recess 20 being at one side of the longitudinal center of the strut 13 and conveniently near the end of the slot 16, it being my purpose that the truss-rod 15 shall be in position at its middle portion to efiectively aid in resisting the strains exerted by the brake-lever.

The truss-rods 14 15 correspond substantially with each other and at their ends pass through'ears formed on the brake-shoe heads 11 and are secured by suitable nuts, whereby the ends of said rods become operatively connected with the ends of the body-beam 10. It

is to be understood, however, that I do not 5 limit the present inventionto the manner of placing the ends of the truss-rods in operative connection with the ends of the bodybeam 10. In the present instance, however,

I provide the brake-shoe heads 11 with the Ico upper and lower ears 21 22, and the ends of the truss-rod 14 are secured in the upper cars 21, while the ends of the truss-rod 15 are se cured in the lower ears 22, whereby said rods become disposed at an angle to and cross each other and are rendered highly efficient for the purpose of resisting the strains exerted by the brake-lever and preventing the upward buckling or bending of the body-beam at its middle portion.

In Fig. 4 I illustrate a modified construction of beam in which the truss-rods 14 extend on converging lines to the outer end of the strut, the latter being recessed to receive said truss-rods and said rods being at an angle to each other and adapted to resist the strains exerted by the brake-lever.

Figs. 5, 6, and 7 illustrate a further modification of the invention and represent the truss-rods 14 15 at an angle to and crossing each other, with the rod 14 in line with the center of the beam 10 and strut 13, as usual, and the rod 15 extending lengthwise of the beam 10 and over the strut 13, which is provided adjacent to its head end with a suitable bearing to receive said rod.

In each form of the invention shown two truss-rods at an angle to each other are employed to increase the strength and durability of the metallic brake-beam as a whole, to more efiectively resist the strains exerted by the brake-lever, and especially to prevent the upward buckling of the beam 10, said rods being so disposed as to accomplish these results and preferably arranged with one rod engaging the outer end of the strut and the other engaging said strut at a point intermediate its ends.

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

1. The brake-beam comprising the flanged rolled body-beam 10, the brake-shoe heads 11 seated on the ends thereof and having the upper and lower ears 21, 22, the strutand the independent truss- rods 14, 15, the said rod 14 at its outer ends being secured in the ears 21 and at its middle portion inclining d ownwardly and engaging said strut, and the said rod 15 at its outer ends being secured in said ears 22 and at its middle portion inclining upwardly and engaging said strut; substantially as set forth.

2. The brake-beam comprising the bodybeam 10, the brake-shoe heads on the ends thereof, the strut, and the independent trussrods 14, 15, the said rod 14 at its outer ends being secured to one end of said heads and at its middle portion inclining outwardlyancl engaging said strut, and said rod 15 at its outer ends being secured to the other end of said heads and at its middle portions extending across the path of said rod 14 and engaging said strut; substantially as set forth.

3. The brake-beam comprising the bodybeam, brake-shoe heads, strut and truss-rods, one of the latter engaging said strut at its end and the other engaging said strut adjacent to the brake-lever slot therein; substantially as set forth.

4. The brake-beam comprising the bodybeam, brake-shoe heads, strut and truss- rods 14, 15, the rod 14 inclining downwardly and engaging the end of said strut, and the rod 15 inclining upwardly and engaging said strut adjacent to the brake-lever slot therein; substantially as set forth.

Signed at New York, in the county of New York and, State of New York, this th day of July, A. D. 1903.

SETH A. ORONE.
