Patented Jan. 23, 1940 PATENT OFFICE BRAKE. HANGER BRACKET David M. Light, Chicago, Ill., assignor to ,Ameri-' can Steel Foundries, Chicago, 111., a corporation of New Jersey Application November 14, 1938,. Serial No. 240,209

13 Claims.

My invention relates to a brake hanger bracket for a railway car and more particularly to a novel arrangement for retaining a hanger in a brake hanger bracket and securing it against 5 Vibration.

It is a Well known fact that wear on brake hangers and on the jaws of brake hanger brackets is principally due to vibration and not due to the normal wear which occurs between parts.

10 Because of this fact many designs of wear plates for brake hanger brackets have been evolved and numerous arrangements for securing the hangers within the brackets have also been devised. The

object of my invention is to provide a novel ar- 15 rangement which will close the brake hanger jaw and provide a substantial amount of Wear metal beneath the top member of the hanger while at the same time providing that'such wear will not result in chattering or looseness of the 20* parts.

Figure 1 is a side elevation of a brake hanger bracket embodying my invention. Figure 2 is a top plan View thereof, and Figure 3. is a sectional view in the vertical plane substantially 251bisecting said jaw as indicated by the line 3-3 of Figure 2.

' Describing the structure in more detail, the truck frame member 2 has the integrally formed brake hanger bracket 4 terminating in a jaw- 30-like structure with the flaring top and bottom walls 6 and l and the substantially vertically arranged rib 8 joining said top wall 6 with said frame member 2. The said jaw structure has also the side walls l and I2, the forward edges 35 01: which are of arcuate formation as indicated at l4, said lateral walls being relatively shallow and forming with the before-mentioned flaring top and bottom walls the'pocket [6 at the rear of said jaw. On the bottom wall I may be seated 40 my novel form of wear plate 18, said wear plate comprising a hook-shaped rear portion 20 having a configuration to seat against the forward edges M of the lateral walls of said jaw. Said hook-like member 20 provides a seat as at 22 for 45 the top member 24 of the loop-type brake hanger 26 of well known form. The forward portion of the wear plate 18 has clearance at the top as indicated at 28 from the flat U-shaped spring 30, said spring having a relatively long leg 3|, 50 the extreme inner end of which has hearing as at 32 against the said top member 24of the'brake hanger, the other relatively short leg 33 of said U-shaped spring 30 overlying thetop .jaw 6 and having a central opening 34 aligned with other 55:

wopenings

36 and 38 in the forward .portions'of the top and bottom walls 6 and l of said jaw' structure and with the relatively large opening 35 in the bottom leg of said spring andthe opening 39 in thewear plate l8. Within said aligned openings maybe received the securing bolt 40 the head of which is seated on the top leg 33 0f the U-shaped spring 30 and the opposite .end of which receives the threaded

nuts

42, 42.

It will be apparent that after assembly of the parts,the U-shaped spring 30 by the bearing at 32 upon the top member of the brake hanger will prevent vibration of that member and of the wear plate I8 upon which the hanger is seated. The bottom surface of the said wear plate it has a configuration complementary to that of the lower portion of the jaw structure and is seated thereupon. The retaining bolt 40 serves to secure all of said parts in position but in addition thereto the wear plate l8 has along its bottom edges the

lateral flanges

44, 44 which overlie the lateral edges of the bottom wall I, thus adding further stability.

It will be seen that my novel arrangement substantially closes the open end of the jaw struc- ,ture and affords compact and efiicient arrangement of parts so cooperating that the tension of the U-shaped spring is efiective to hold all parts in secure and tight relationship with one another after the retaining bolt has been secured in position. 30

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown which is merely by way of illustration and not limitation as various and other forms of the device will, of course, be apparent to those .35 skilled in the art without departing from the spirit of the invention or the scope of the claims.
