Application March 15, 1932, Serial No. 598,957

6 Claims.

My` invention relates to means whereby the brake hangers of railroad cars are pendently and swingingly supported from the laterally disposed lugs or arms usually formed integral with the truck frame.

My invention has for its object the provision of a retainer which may be readily put into place and its removal, when occasion requires, as readily accomplished, and the hangers or links held in proper brake-applying position; while at the same time wear resulting from' the vibratory and swinging movements of the hangers, will be takenzcare of by the retainer and a non-chattering relation between the retainer and the truckframe provided. i

The objects and advantages of my invention will be readily comprehended` from the following detailed description of the drawing, wherein:

Figure 1 is a side elevation of an arm or projection integral with the rtruck frame, a portion whereof, partly in section, is shown and the' upper portion of a'hanger.

Figure 2 is a vertical sectional view taken substantially on the line 2-2 of Figure'l. i

Figure 3 is a perspective View of one member of the retainer.

Figure 4 is a perspective view of the other member or element of the retainer.

` My improved retainer is especially intended for usewith a truck frame having a suitable pocket or socket adapted to receive the retainer with one end of the hanger and in the particular exemplification a portion of a truck frame is shown at V10,

`provided with an arm or extension 11 usually formed integral therewith and disposed in a direction transversely of thetruck. The outer end ofthe arm on the wheel side thereof is provided with integral laterally disposed

lugs

12, 13, spaced vertically apart to provide a pocket or socket therebetween 'as shown in Figure 2. l

The pocket or socket formed by the spaced apart

lugs

12, 13 is intended to receive my improvedl retainer which consists of the two` elements or

members

15 and 16 shown -in Figures 3 and 4; the

lugs

12, 13 being connected intermediate of their sides by the spaced apart

vertical webs

14, 14.

The member 1 5, which may be termed the inner or main member, preferably comprises a casting somewhat U-shape in cross-section, having an arcuaterear wall 15a, with the intermediate p0rtion thereof preferably provided with the right

angular rib formations

17, 17 extending beyond the curved portion of the rear wall. These

ribs

17, 17 not only reenforce the member but also (Cl. 18S-209) enter into the rear end of the pocket between the webs 14 in lapping engagement therewith; the forward faces of the webs generally being arcuate and therefore adapted to receive the arcuate or curved ends of the retainer member 15. 60.

The rear wall of member 15 constitutes substantially one-half of an annular socket or channel formed by the proper positioning of member 16 within member 15.

The two

sides

18, 18 of member 15 are off-set 65 from the inner arcuate face of the end wall 15a; that is to say, the sides 18 are shown of slightly less thickness than end wall 15a so as to provide the

inner shoulders

19, 19, disposed in the same vertical plane with each other and extending 7.0 lengthwise of the member.

The outer forward end of each side 18, intermediate of opposite ends of the member, is shown provided with the arcuate recess or socket 20; while the outer faces of the

side portions

18, 18, 75- about the sockets 20, may have the rectangular countersinks or recesses as shown at 21 to receive a well known type of bolt retaining element not shown. v

The complementary member 16 also preferably 80 consists of a suitable casting or block consisting of the two

sides

22, 22 and the intermediate body portion 23 formed to provide an arcuate channel or socket 24 on its hangeriengaging face. That is tosay, the arcuate face 24 is formed to 35 constitute, in conjunction with the curved wall 15n of member 15, an annular socket adapted to receive the end of the brake hanger or link 25 as disclosed in Figures 1 and 2 where the upper end `of a continuous link type of brake hanger 90 is shown.

The rear or outer wall of member 16, intermediate of the ends, is provided with a vertically disposed arcuate socket at 26 to provide passage for the `retaining orV fastening bolt 27 which 95 passes through suitable holes in the top and

bottom lugs

12 and 13. The top and bottom sides of member 16 are preferably provided with a similar arcuate rib or boss 28 about the socket 26 and these ribs 28 are intended to enter the 100 respective arcuate socket 20 of member 15 when member 16 has been properly inserted inmember 15.

As is apparent from Figure 2, after the end of the link 25 has been put into place against 105 the arcuate rear wall of member 15, member 16 is then forced into place between the sides 18,

18 of member 15, with the arcuate socketed face 24 disposed toward the link. Member 16 is intended to be moved into member 15 until the 110 bil forward flat longitudinal edges or faces 29 of member 16 are in engagement with the

shoulders

19, 19 of member 15, at which time the arcuate bosses or ribs 28 of member 16 will also be seated in the arcuate sockets 20 of member 15.

Shoulders 19 and arcuate ribs 28 act as stops for determining the interengaging relation between the two members and hence prevent a binding relation with the ends of the links 25 and permit free swinging movement of the latter.

The top and bottom sides 22 of member 16 are preferably given a slight taper toward the entering edges 29, as shown in Figure 4; and the inner faces of the top and bottom walls 18 of member 15 are preferably also correspondingly tapered toward the forward free edges thereof, so that when member 16 is driven into member 15, it will tend to spread the top and bottom walls 18 of member l5 into rm frictional or binding relation with the bracket forming lugs l2 and 13 of the truck frame.

I have described what is believed to be the simplest embodiment of my invention and have described the same interms employed merely for purposes of description and not as terms of limitation.

What I claim is:
