BRAKE-BEAM.

Specification of Letters Patent. Pat t d 2 1912,

' Application filed February m, 1912. Serial No. 677,035.

To all whom it may concern:

Be it known that I, HENRY ZIEMss,-Jr.,- :1

- citizen of the United States, residing at Chicago, State of Illinois, have 'inventeda certain new and useful Improvement 1nv Brake-Beams, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the'accompanying drawings, forming part of this specification, in

Figurel is proved brake beam. Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 3 is a sectional-view on line 3--3.of-Fig. 1.

This invention relates to a new and useful improvement in brake beams, the object being. to provide a simple, cheap and strong .beam, the essential feature of my invention consisting in s'plittingand separating the compression member. so as to form a trussed compression member. Means are also provided for spacing and holding together the,

split portions of the compresslon member. 4 In the drawings 1 indicates the compression member and 2 is the tension member.-.

The compression member is shown as being formed of atube of proper length, said tube being split in a vertical plane at its middle portion, so as to form two portions 1 and 1 the ends being preferably left integral; These split portions are most widely separated'at the middle of the beam.

3 indicates the strut interposed'between the portion 1" and the tension member 2, said strut being provided'with the usual an'gu-i lated 'slots for the brake lever. 'Thisstru't} as shown in. Fig. 2 is provided with aQseat in which the-member 1 is received, the upper wall ofthe strut being separatedby a may be enlarged at 2 to lncrease its d1- slot 3 so that said upper wall forms a tongue which may be sprung-over the member l 'in tween the members I and 1}, and serves to hold said members separated.

Thelo'wer wall 4 at the rear end "of the strut is provided with lugs 5 for the pur pose of separatingthe' members Iand 1",-

.said lower wall continuing upwardly around 'the inember '1 to form a strap portion 7 having openings in its end for receiving the projections 8 on the tongue 6, which projections are adapted to be hammered down a top plan view of'my imbrake position. Instead of integral projections 8' rlvets may be employed to secure the tongue and strap portions together.

10 indicates sleeves which maybe employed to strengthen the trussed compression member at points intermediate the central strut and brake heads. These sleeves are provided with pins 11 which pass between the portions 1? and 1, adjacent the inner edges thereof and are riveted to the sleeves- 10' as shown in Fig. 3.

The ends of the compression and-tension to form heads so as to hold the tongue in Y members may be secured together in any suitable manner and are preferably provided with sleeves 16 on which the brake heads 17 are mounted; As shown at the left in Fig. l, the ends of the tension member pass through theopenings in the inner walls of the ends of the compression member and a washer 13' is placed over each end of the tension member said washer having a seat l-it'fo'r abutment of the compression member and having an inclined outer face fora nut 15 which is threaded on the end of the tension member and impinges against said washer. By this means the tension and compression members are secured together independently-ofthe sleeve loand for repair purposes the sleeve may bememo'ved and renewedwithout disturbing the trussed beam.

' The sleeve 16 preferably fits over the ends ofthe compression and tension members and is provided with an inclined end wall 16, which houses in the nut 15 and preferably bearsQ- ithereagainst, and its side wall' is formed to admit the tension member and provide a-seat or passage for it, .as-shown The sleeve is secured'in position by Ifdsired' the end of the tension member 2 ameter and thus afford a larger bearing for the nuts '15 and 18. Upon the inner end of the sleeve is-formed a flange or shoulder 19 against which the ead is received. Y f What Iclaim' is: 1'.'A'--brake beam comprising a'compression member and a tension member, said compression member being oftrussed construction, the chords of'the truss lying in the plane of the brake beam, and-a strut extending between said tension member and said compression member, said strut having for said said compression member, said strut having means at one end adapted to hold the parts of said compression member separated, and to prevent further separating movement of said parts.

3. A brake beam comprising a "compression member and a tenslon member, said compresslon member being spllt longitudinally for a portion of its length, the middle portion of the halves being separated, said' halves lying in the plane of the brake beam strut, means for holding said middle portions apart, and a strut extending between said compression member and said tension member.

4. A brake .beam comprising a tenslon member and a compression member, said. compression member comprising a tube having a longitudinalslot therethrough, the two portions formed by said slot being spaced apart at their middle point, and a strut extending between said tension member and said compression member, said strut having means for holding said portions of the compression member separated, and for preventing further separating movement of saidportions.

5. A brake beam comprising a tension member and a compression member, said compression member comprising a tube having a longitudinal slot therethrough, the two portions formed by said slot being spaced apart at their middle point, a strut extending between said tension member and said compression member, said strut having means for holding said portions of the compression member separate and for preventing further separating movement of said portions, and sleeves surrounding said com pression member, said sleeves limiting separating movement of said portions, and

means carried by said sleeves for limiting v the movement of said portions toward each other.

compression member being tubular and having a longitudinal slot therethrough, theportions formed by said slot being separated attheir middle point, and a strut extending between said tension member and said compression member, said strut having portions adapted to lie in said slot for holding said portions separated, and a strap extending about said compressionmember and being connected to said portion of saidstrut.
