To (ZZZ whom it 122/4 7, concern):

Be it hnownthat l, EDWIN Bessie, a citizen of the United States, residing Chicago, county of Cook and State of Illinois have'invented e certain new and useful lin+ prominent in Reversible Struts for Brake Beams, of which the following is tlull, clear and exsct'dcscription, such aswill enable others skilled in the art to which it up pertains to make and use the same, refe ence being had to the accompanying drawings, forming part of this application. Figure l is a sectional view through a brake beam showing my improved reversible strut in position.

l'ligurefl? a similar view through. the tension seat or d of the strut, showing; a n'iodined form.

Figure 3 motlificution,

lfiigure "l: is a view of another HIOCllllQtl 't'oiin.

Tl'iis invention rel;

" 'ovcinent in is a similar view of another to a new and useful ole struts tor brake liieanzs and is designed articulsrly as an in i'cincnt upon that ii: 01 revel i "n in the Johns Patent No. 4i? 15, 1. ml. and the 1 34:0468, dated May 18, 1920; the ob} :"s or my prese t lllT'GIlilOl] being to sinipuiy the construi 'ion and by the use ol bolts, .7 or other fastening devices, enable the hes-in to be repaired.

In the drawings, 1 indicates thercon'ipression member, and 2 the tension member of a trussed brake beam. openings l through which passes the pin on which the brake lever, not shown, is mounted. Each end of the strut shown in Figure 23 dated intoon Pa tent No.

1 is provided with. a hollow cylindrical trunnion-like extension 5 from the outer faces of which extend hollow bosses 6 form- 3 is the strut having whereby thestrut be held in adjustable position for right and left hand brake levers.

12 indicates n1 casting whose outer end is provided with 'afseatdor the tension her 2, said casting having an inwardly extending flange 13 through and beyond which projects a boss 6"" on" the "outer end of the s rut. The inner end of casting12 is pro'vi I with en o wsrdly jextending' which r of the str fasteningdevice, a bolt, by which the strut is secured in proper adjusted posi tion to the casting 7Q Itwillhe notedthat the outer head of this rivet (or bolt head) bears against the face of the boss 6 and is not in direct contact with the flange 8. Hence by the else we thus provided, the parts may he s" l ;o be held together by the pressures e r, by the compression and tension memoei's but should either of these members break, the rivet or other fastening device would prevent separation of the parts The rivet or fastening device 16 wiiici secures the tension member seat to the end oft-he strut likewise bears s' as outer face of the boss 6.

0 not wish to confine myself to the use 'eiesses 10 and lugs 11 as it means for c 11 the strut in adjusted position, as y yell-known means may be employed tor this purpose. The tension seat ispretera 1y left of the strut and has no means for holding r in any fixed position. i

In Figure 2 l have shown an inversion of the parts illustrated in Figure 1 in which the strut 17 has a flange 18 and a cylindrical bore or sent in its outer end beyond this flange. 19 is a tension seat having an inwardly extending]; boss 20 which projects beyond the inner liztce of flange 18 that Iwhen the rivet 21 is placed in position itwill be seated against the inner face ot boss 20, and extending over the inner insrgins]. edges of flange 18 will prex ent acci dental displacement of the parts while per miting their rotation. y

In Figures 3 and l, I have shown modified forms in which strut 17 has a socket in its end, said socket being formed by an apertured seat 18, as shown in Figure 2. Instead ol having pivotal member or boss termed integral with the parts, I provide-the tension against theend wall] 15 inuicutes a rivet or other rod seat 19Hwith a registering aperture in its inner wall and arrange a separate pivotal member or sleeve 22 in the registering apertures, which sleeve is slightly longer than the thickness of'the two contiguous aperturedwalls. A rivet 23 is shown as a rastening'device, and when upset this rivet will have both of its heads bearing directly upon theend faces of the sleeve inthe manner heretofore described with relation to the boss shown in Figures 1 and 2.

, In Figure 4, I have shown the sleeveas having an outwardly extending flange 24:,

which flange is designed to receive the upset end of the rivet 23 and prevent the marginal edges of the upset head of the rivet. from contacting with the tension rod seat, which might occur in the "form shown in Figure 3.

-In all the forms shown, it will be observed that the rivet heads engage opposite faces of the pivotal member whether boss or sleeve, and, consequently, the parts mounted upon the pivotal member are free to rotate without binding contact with the rivet in each instance. These bosses or sleeves are, therefore, designated as pivotal members, and when the rivets or other devices are in eas es sion, a pivotal member arranged in axial alignment with respect to said parts, and holdlng devices which engage the opposite iaces 0t said pivotal member.

2. In a brake beam, the combination of tension and compression members, seats therefor, a strut, interengaging trunnionlike extensions and recesses in said parts, respectively, pivotal sleeves on which said parts have a relative turning movement, and fastening devices having shoulders which bear, against the end faces of said pivotal sleeves for holding said sleeves in position.

In testimony whereof I hereunto afiix my signature this eleventh day of February,

, EDWIN e. BUSSE.
