(fCl. 18S-209) 12 Claims.

My invention relates generally to a brake arrangement for a railway car truck and particularly to a novel form of hanger associated therewith.

The general object of my invention is to devise a novel form of brake hanger which may be resiliently supported from an adjacent :brake frame member and conveniently applied or removed as may be desired.

A specific object of my invention is to devise a novel form of brake hanger and support arrangement wherein the truck frame member may be formed with angularly arranged support means on which may be resiliently carried my novel brake hanger wear block and from which may conveniently be supported a brake hanger of usual form.

My invention comprehends an arrangement wherein the brake frame bracket may be so formed as to slidably receive my novel wear block, both said wear block and said bracket being arranged for the interposition therebetween of resilient means, in order that wear between the parts may be reduced.

In my novel arrangement the brake frame bracket may provide support for said wear block at opposite sides thereof and the brake hanger may depend through an opening formed in said wear block in alignment with a slot formed in said bracket.

In the drawings,

Figure 1 is a side elevation of my novel brake hanger arrangement, only a fragmentary portion of the frame member being shown and likewise a fragmentary portion of the brake beam and the adjacent wheel.

Figure 2 is a fragmentary top plan view of the structure shown in Figure l, and Figure 3 isan end' view thereof, taken from the left as seen in Figure 1 approximately in the plane indicated by the line 3 3.

Figure 4 is a view taken from the right as seen in Figure 2 approximately in the plane indicated by'theline 4 4' and illustrating the frame bracket only.

Figure 5 is a sectional View through the frame bracket, the section being taken approximately in the longitudinal vertical plane indicated by the line 5 5 of Figure 3.

Figures 6, '7, 8, and 9 show in enlarged size the detail of my novel form of Wear block, Figure 6 being a top plan view thereof, Figure 7 a side elevation, Figure 8 a side view thereof taken from the right as seen in Figure '7 approximately in the plane indicated at 8 8, and Figure 9 a sectional view'transversely through the wear block approximatelyinr the plane indicated by the line 9 9 of Figure 7.

Describing the structure in detail, the truck side frame member 2 comprises the inturned end bracket 4 from which may be supported the brake hanger 6. The lower end of said hanger may have pivotal connection as at 8 to the brake head I0, said brake headV being secured as at l2, l2-on the end of the :beaml Irl and supporting in usual manner the brake head i6 for engagement with the periphery of the adjacent wheel I3. Inwardly of the wheel, the brake beam l 4 may have secured thereto the fulcrum 2! for connection to operating means in usual manner.

The bracket 4 may be a box-like structure comprising a top wall 22, a rear wall 24, a diagonally arranged

bottom wall

2,6, an end wall 2B, and a vertical web 3@ parallel with said end wall but spaced therefrom so that the hanger 6 may loe-supported therebetween. The bottom wall 26 may be slotted as at 3l in alignment with the space between the

walls

28 and 36 and the topi face thereof may be diagonally arranged so that under normal conditions the hanger 6 will bev supported approximately at right angles to said bottom wall or ledge 26,1 thus avoiding a resultant of forces tending to drag the hanger oii the shelf or ledge 2li. The end wall 23 and the spaced web 30 may be cored away at their lower edges, the bottom edges thereof being diagonally arranged and parallel with the diagonally arranged bottom wall 26. The bottom edges of the wall 28 and the web 36 may be slotted as at 32, said slots being aligned for accommodation of the brake hanger supporting threaded,`

bolt or pin 34. The upper end of the hanger 6 may have pivotal connection as at 36 with my novel form of wear block generally designated 38, said wear block being slidably received in the end of the bracket 4 and being insertable therein from the inner and open face thereof as viewed at 4 4 (Figure 2) Thus the Wear block 38 may seat on the bottom wall 26 at lopposite sides of the slot 3|, the portions of said bottom Wall thus forming a jaw-like structure between which the hanger 6 may depend, while at the same time, the

spaced walls

28 and 30 form rigid means together with the adjacent upstanding portions or

flanges

42, 42 of said wear block for the hanger securing pin 34. v

The said block 38 may be a generally rectangular structure with a bottom wall 66 having the central rectangular brake hanger slot 4l and formed with upstanding

lateral anges

42, 42,

said lateral flanges being formed with aligned perforations and said bottom wall slotted to dene the pin opening d4 within which may be received the securing pin 34, already referred to. On the bottom face of the wall 40 and at opposite sides thereof may be secured parallel rub-

ber pads

46, 46, said rubber pads being vulcanized thereto or otherwise secured as may be convenient. l

It will be understood that the rubber pads 46, 45 afford bearing for the wear plate or wear block 38 on the bottom wall 26 and after said wear plate has been inserted in normal position, the upper end of the hanger 6 may be elevated into normal relationship therewith, after which the securing pin may be inserted. With the securing pin in place the wear block and the hanger are rmly seated and the hanger is aorded sufficient resilience to reduce noise and greatly lessen wear between the parts.

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 skilled in the art without departing from the spirit of the invention or the scope of the claims.
