8 Claims.

My invention relates to'means whereby'the brake hangers of railroad cars are pendently supported and retained in place in the sockets formed by the laterally disposed brackets or arms generallyformed integral with the truck frame; my improved retainer being more especially adapted for use with the link type of brake hanger at present employed.

The invention has forits object the provision of means which maybe easily assembled and readily removed, when occasion requires, and whereby proper brake-shoe key clearance will be provided during brake-shoe replacement, and thehangers or links will be held in proper polo sition.

means; the different parts of said means being adapted to compensate for variations in the di mensions of the bracket opening.

The foregoing enumerated objects and ad- Vantagesof my invention, as wellas other advantages inherent in the construction, will be :more readily comprehended from the detailed description of the accompanying drawing,

wherein- Figure 1 is a side elevation of the supporting arm or bracket of the truck frame, a portion of io the truck frame being shown in section, with the lower'part of the link or hanger bro-ken away and my-improved retainer means secured in' place.

Figure 2 is a Vertical sectional View taken along "the line 2-2 of Figure 1.

Figure 3 is a cross sectional view taken on the line 33 of Figure 2 looking in the direction of the arrows.

Figure 4 is a perspective View of the link-en- .jgaging side or inner face of one member of the retainer means.

Figure 5 is a perspective view of the socket or outer endportionof the supporting arm of the truck frame.

55": The retainer' consists of a pair of-comp end of portion I 4 toward the other.

tary members Ill identical in construction and adapted to be arranged in superposed relation to provide a suitable jchannel to receive one end of a hanger H therebetween; the superposed members ll] being intended to be inserted intothesocket I2 formed in the extension or arm l3 whichis generally formed integral with the truck frame a portion of which is shown at A.

The brake beam hanger pocket or socket 12; at the free end of the laterally disposed arm 13, is formed by the vertically spaced portions 'or walls l4, Hi. The longitudinal edge of the portion [4 on its inner surface is provided with a flange or transverse shoulder l6 which tapers or increases in transverse dimensions from one This flange It, at an intermediate point, is shown provided with an enlargement or boss I! extending inwardly toward the closed side of the pocket I2. see Figure 5. The longitudinal'edge of the other portion or walll5 is also provided with a flange or shoulder 1B, which also tapers or increases in transverse dimensions like shoulder IE, but the taper is inthe opposite direction from the taper of shoulder l6, as shown in Figure5.

The pocket l2 the arm I3, in addition to receiving the link or hanger ll, is also intended to receive the link or hanger retaining means consisting of a pair of plates or members l0, H) which are identical in construction. The construction of these plates is more clearly shown in Figure 4 where the hanger receiving side of the plate is shown with one longitudinal edge of the plate curving toward the hanger receiving side as shown at 19, to constitute one side or wall of the semi-cylindrical groove whose opposite side or wall is formed by the longitudinal rib 2|.

The rib 2| at one end of the plate terminates in the laterally disposed ear or lobe 22 provided" with a suitable bolt-receiving hole 23. The 1ongitudinal rib 2! is arranged a slight distance removed from thelongitudinal edge 24 of the plate I and this distance increases toward one end because the transverse width of the plate increases toward the end provided with the lobe or ear 22-. As a result themember is provided with a tapering or sloping longitudinal edge-24 which corresponds in degree of slope: or taper to the, taper of the shoulders I 6 and It in thevsocket: or pocket l2 of the bracket arm I3. I i

The longitudinal side- 24," intermediate of the ends of the plate, is also provided with an indentation or socket 25 of dimensions sufficient I to receive the enlargement or boss l'l when the plate is inserted in the pocket I2; the boss I! and socket 25 providing an interlocking engagement with the particular member l which contacts the walls of socket l2 provided with boss II.

This causes the said member to be held against lengthwise movement during insertion of the other member ID and allows a binding relation between both members In to be effected.

In assembling my improved retainer means, one member ID, with the upper end of the hanger in its groove 20, is first inserted in the pocket or socket I2 of the supporting arm l3; the member l0 being positioned so that the enlargement or boss ll on the lower wall of pocket I2 is in register with and enters the socket 25 in the longitudinal side 24 of the member Ill. This causes an interlocking engagement whereby the proper position of the initially inserted member I 0 is determined and sliding movement of the member lengthwise of the pocket prevented. After the lower member with the superposed hanger II is in place as described, the second or upper member ID is then inserted endwisely into the pocket with the narrow portion of the longitudinal side or flange 24 initially entering the pocket.

The gradually increasing lateral flanges of the two members cooperating with the oppositely tapering flanges on the upper and lower walls of the pocket or socket, will cause the two superposed members to be forced toward the rear or inner side of the pocket or socket.

The superposed relation of the two members I0 and the wedging of said members toward the rear or inner side of the socket is controlled and effected through the action of the nut 26 screwing lengthwise of bolt 21 which latter is inserted through the apertures 23 in the lobes 22 of the superposed members l0, l0.

As previously stated, the two members l0, l0

are identical in construction and, therefore, when arranged in the superposed relation, namely with the grooved face 20, of the bottom member disposed upwardly, the lobe 22 of said bottom member will be located at the right as viewed in Figure 1, while the lobe 22 of the upper member l0,

when its grooved side 20 is facing downwardly as in Figure 4 will be located at the left as viewed in Figure 1. That is to say, the lobes of the two members will be located at opposite ends of the socket or pocket l2. It is apparent from this arrangement that the screwing up of nuts 26 against one lobe or ear 22 brings the head of bolt 21 against the other lobe or ear and exerts pressure on the superposed plates in opposite longitudinal directions and induces a snug relation between the tapered flanges 24 of the members l0 and the tapered flanges l6 and I8 on the Walls of the pocket or socket I2, with the result that vibration and chattering of the retainers are prevented.

With both members I 0 identical in construction any wear that may take place on the lowermost member ID (the member which carries the hanger and weight of the brake mechanism) can be taken up by reversing the members with the result that the brake mechanism will always be maintained at the proper elevation required for effective braking operation.

With my improved retainer wherein the superposed members, through the action of the tapered flanges, are wedged toward the rear of the socket, compensation for variations in the dimensions of the pocket or socket is afforded and means for holding the superposed members tight- 1X31!) the;brackets is, also provided.

With my improved retainer means shown and described, greater clearance for the brake shoe key is provided during brake shoe replacement, because the need for perpendicularly disposed bolts as heretofore employed is eliminated.

I have described what I believe to be the best embodiment of the invention, although it may be possible to somewhat modify the particular construction shown without departing from the spirit of the invention as defined by the appended claims.

What I claim is:
