BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent N 0. 754,785, dated. March 15, 1904.

Application filed SeptemberZ, 1903. Serial No. 174,396. (No model.) I i To all whom, it may concern:

Be it known that I, ARTHUR LIPSGHUTZ, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Brake-Beams, of which the following is a full, clear, and exact-description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a brake-beam of flanged form having its end portions upset and the ends of the flanges compressed to the web of the beam to provide for the reception of the brake-heads while retaining the utility of the 5 flanges throughout the central portion of the beam. The invention further relates to a novel construction of finger-guard used in connection with the beam.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure l is a top or plan view of my beam,

partly broken out. Fig. II is a rear elevation of the beam, partly broken out. Fig. III is an 5 end view of the beam with the brake-h-.;1ds

omitted. Fig. IV is a cross-section taken through the beam at the location of tlie fingerguard thereon on line IV 1V, Fig. I. Fig.

V is a horizontal section takenon lineV V,

3 Fig. IV.

My beam is preferably made from a body of I form, though it may partake of any other shape in cross-section; such as a T. The construction shown in the drawings is of I form, and the beam has a web 1, forward side flanges 2, aadrear side flanges 3. At each end of the be jportions of the rear flanges 3 are upset and the flanges are bent over onto the web 1, from which they project, and the end portions 1,0 of the beam are compressed toward the forward edge of the beam, so as to produce a thickened web as a result of theupsetting and bending of the rear flanges and the compression of the end portions of the beam. These end portions receive the brake-heads 4, which are secured to the beam in any suitable mannor, such as by bolting them thereto.

5 designates a brake-lever fulcrum mounted 'the upper rear flange 3 of the beam to thereby centrally'uponthe brake-beam at the usual. location.

6 designates a finger-guard that projects out a wardly from the rear of the beam land is furnished with an arm 7, which passes through 1 the web 1 of the beam and is secured thereto h by a key 8, as seen in Fig. IV. In lieu of said key a nut may be applied to the arm of the finger-guard, as shown by dotted lines. For the purpose of holding the finger-guard properly positioned with relation to the brakebeam-that is, at right angles thereto1 util- 6o ize a clip fitted to the-.fingerguard and having engagement with the upper rear flange of the beam. This clip has a sleeve 9, encircling the finger-guard, and a socket l0, that is fitted to 5 hold the clip from movement on the lingerguard and prevent lateral movement of said finger-guard. 11 is a curved. leg projecting from the clip-sleeve 9-downwardly to the web 1 of the brake-beam at the rear of the tinger- 7 arm 7. This curved leg is formed into a fork 12 at its termination, and said fork is fitted to the finger-guard arm 7 to thereby cause the leg 8 to serve as a brace for the clip-sleeve 9. 'Ehe leg 11 also serves to receive the brake -7 5 safety-chain which is secured thereto.

The important feature in my brake-beam construction is the reduction of the width of the ends of the beam without weakening effeet and to furnish a form of beam end to which the brake-head may be applied in the most secure manner and without making the head of aweak form. Brake-beamsthat are -made for use between pairs of truck-wheels of a railway-car must necessarily be narrow 5 enough, particularly at their ends, to operate without interference with each other, owing to the limited space between the two sets of truck-wheels in connection with which the two brake-beams, with their heads, are used. 9 In view of what is stated in the foregoing I compress my beam at the ends to narrow it, and in order to attain the full strength of the beam at the compressed portions I compress the flanges of the beam onto the web of the beam, and thereby thicken the ends of the beam in a degree corresponding to the thickness of the compressed flanges. By so compressing the flanges onto the web of the beam instead of merely compressing the beams ends and permitting the flanges to'remain uncompressed, but merely offset from the remainder of a the flanges throughout the body of the beam, 1 furnish a broad bearing fdr the brake-head. As a consequence of thfs broad bearing ample space for the bolt and rivet holes through the thickened ends of the bean] is provided so that there may not be the least difiiculty in maintaining the heads on the beam ends. Moreover, full body in the brake-head without any Weak points is rendered possible. owing to the flat form of the beam ends, instead of incurring weakness in the brakehcads Where made of a form that will fit to the flanges of a bean'rover which the head must be fitted.

I claim as in invention- 1. As a new article of manufacture, a brakebeam of flan; :1 form having portions of the flanges at its ends upset onto the web of the beam, substantially as set forth.

2. Asa new article of manufacture, a brakebeam of flanged form having portions of the flanges at its ends upset onto the Web of the beam thereby furnishing ends of T shape, sub: stantially as set forth.

3. A brake-beam of flanged form having portions of its flanges at the ends thereof upset onto the Web of the beam, and having said ends compressed to thicken the brake-headreceiving parts of thebeam, substantially as set forth.

4:. The combination with a brake-beam of flanged form, of a finger-guard having an-arm passing through the Web of said beam, and a clip for securing said finger-guard to the beam; said clip comprising a sleeve fitted to the finger-gua'rd, a socket projecting from said sl core to engage one of the flanges of the beam, and a leg extending from said sleeve and having a forked end fitted to the arm of said lingerguard, substantially set forth.

The combination with a brake-beam of flanged form, of a finger-guard having an arm passing through the web of said beam, and a cli p for securing said lingerguard to the beam, substantially as set forth.
