26 Claims.

My invention relates to journal boxes for use on railway cars and has particular reference to means for protecting the journal box lugs against wear,

In the present day railway car trucks, the journal box is generally formed a an integral part of the side frame. On the top wall of the box is provided an integral cam-faced lug to which is hinged a lid or journal box cover, said lid carrying resiliently actuated means slidably engaging the said cam faces by means of which the lid is held either in closed position or in open or elevated nal box lids. These means, on opening and closing the lid, eventually wear away not only the cam faces against which they bear, but also the opening in the lug through which passes the pin or pintle affording a pivotal connection for the lid. Any looseness in this connection permits the lid, upon movement of the car, to flap and vibrate, consequently accelerating the wear of the engaging parts.

Refacing or building up worn cam faces is an expensive operation and if the journal opening in the lug is also worn, refacing the cam faces alone will not entirely eliminate any looseness in the assembly. Replacement of the lug is impractical since it involves not only the cost lug, by cutting it off the box, but also the arduous task of properly positioning and welding on the new lug.

I have devised means to overcome these diffculties, and it is the object of my invention to provide inexpensive, easily replaceable wearing means on the journal box lugs.

My invention contemplates providing on the journal box lugs readily replaceable wearmeans comprising a cam face sheathing portion and bushing portions, the sheathing portion being sleeved over the cam faces of the lug and the bushing portions fitting into the journal opening in the said lug.

These and other objects of my'invention will be apparent from the specification and drawings,

wherein Figure l is a fragmentary top plan view of a journal box embodying one form of my invention with one of the parts of the novel wear means being shown in pre-assembly position;

Figure 2 is an elevation of the assembly shown in Figure 1 with the partsin' finalassembled position, the left half being a front elevation thereof, and the right half being a rear elevation thereof with a portion of thejournal box being shown in section, as indicated by lin 2-2 of Figure 3 position, as is common in jour-" Figure 3 is a fragmentary sectional view of the assembly taken in the transverse vertical plane substantially as indicated by line 3-3 of Figure 2; 1

Figure 4 is a top plan view similar to that shown in Figure 1 and embodying a modification of my invention;

Figure 5 is a view in elevation of the assembly shown in Figure 4, the left half of Figure 5 being a front elevation, and the right half-a rear elevation, partly in section, taken in the plane indicated by line 5-5 of Figure 6';

Figure 6 is a sectional view taken in the trans verse vertical plane substantially as indicated by line 6-6 of Figure 5; and

Figure '7 is a sectional view similar to that of Figure 6 and showing another modification of my invention.

Describing my invention in detail and referring first to Figure 1-3, the journal box (fragmentarily shown) generally indicated 2, comprises a top wall t on the top of which adjacent the outboard edge thereof is formed the integral lug, generally designated 6, said lug comprising the integral inwardly flaring spaced parallel legs or pedestals or-

bracket ribs

8, 8 at opposite ends thereof, said ribs including hub portions Ill (Figure 2) between which extends the integral member or body [2 of the lug formed with cam faces 14 and I6 (Figure 3) at the front and top thereof, said member also having a rear face 18 and being necked down orrecessed as at H, at the bottom where it joins the said journal box top wall 4in the usual manner and presenting the converging under

surfaces

20 and 22. An opening 24 is provided in the lug 6, said opening extending transversely of said ribs through the hub portions thereof and-longitudinally through the said member 12, the opening 24 being adapted toreceive a pin or pintle means (not shown) journaled in the lid (not shown) inthe usual manner.

Awear member 26 is sleeved over the lug 6, the wear member 25" having at opposite ends thereof the downwardly bent flat annular disc tures merging into the integral intermediate wear plate or sleeve or sheathing portion 34 contoured to the said member I2 and having the angularly

related webs

36, 38 and 40 corresponding in angularity to that of said faces I4, I6 and I8 (Figure 3) respectively and tightly pressed thereagainst and encompassing the same.

It will be appreciated from a consideration of Figures 1-3 that the

webs

36 and 38 of the mem ber 34 thus provide the

cam surfaces

42 and 44 against which an associated member (not shown) may bear in the usual manner for hOlding the lid on which it is usually mounted in normal open or closed position.

To secure the sleeve 34 to the member I2, the lower edges of the

webs

36 and 40 are curled under the said under

surfaces

20 and 22 of the member I2 as at 46 and 48 respectively, as illustrated in Figure 3.

Within the opposite ends of the opening 24 are positioned bushings 50 which may be provided with annular plates or

flanges

52, 52 of the end caps, each bushing passing through the opening 30in the adjacent element 28 and thus additionally securing the wear member 26 to the lug I2. The flanges 52 are each held in assembled position on the lug I2 and interlocked therewith by the integral arms 56 projecting from one side of each annular plate 52, said arms passing behind the adjacent bracket rib 8 and being bent against the inner surface thereof as at 51, as shown in gure 3.-

In assembling the device shown in Figure 1, the preformed wear member 26 is sleeved over the lug so that the

cuplike structures

32, 32 of the said member fit snugly on the hubs I0, I of the lug and at the same time the

webs

36, 38 and 40 fit snugly on the faces I4, I6 and I8 respectively.

Thereafter, the

portions

46 and 48 of the

webs

36 and 40 are bent inwardly into the respective recesses I1, I"! of the lug until they bear against the respective surfaces and 22.

The bushed portions 50 of the end caps are then inserted through the openings in the disc elements 28 in the wear member 26 and extend into the opposite ends of the complementary opening 24 'in the lug at which time the flanges 52 of each of the end caps bear against the outer face of the adjacent disc elements 28. The arm 53 of each end cap is then bent around the adjacent rib 8 so that it snugly engages the inner surface of the said rib 8.

Referring now to Figures 4-6 illustrating another form of my invention, it will be observed that the construction of the lug I00 is unchanged from that described in connection with the previous modification, said lug I00 being mounted on the top web I02 of the journal box, generally indicated I04, and having the inwardly flaring bracket ribs or legs I06 at opposite ends thereof with the hub portions I08 between which extends the integral member IIO having the usual cam faces H2 and H4 at the front and top; thereof, and the rear face II6 (Figure 6). The lug is necked down or recessed as at H! at the bottom thereof providing the under surfaces [I8 and I20.

Within the lug I00 is provided the'opening I22 serving the same purposes as the opening 24 described in connection with the previous modification. 7

On the opposite ends of the lug are positioned the wear members generally designated I24, I24, each of said members comprising an annular disc or flange portion I26 having a centraliopening I28 which may be formed by extruding, the bushing' I30 from said disc, said bushing I30 fitting into the adjacent end of the said lug opening I22.

Each disc portion I 26 rests against a side I32 of the adjacent hub portion I08.

An arm I33 extends from the edge of each disc portion I26 and passes behind the adjacent rib )6, said arm carrying an integral wear plate or sleeve or sheathing member I34 preferably projecting at right angles therefrom and contoured to the faces of said lug by being bent thereover in such manner that it closely adheres to said faces. It will be observed in considering Figure 5 that the sleeve or sheathing members I34, I34 of the wear members I24, I24 are arranged in tandem and substantially cover the lug faces from end to end and provide the cam surfaces I36 and I38 upon which may ride in the usual manner the resiliently actuated member (not shown) carried by the journal box lid (not shown) To more adequately secure the sleeve member I34 to the lug I00 the bottom edge of the web portion I 40 (Figure 6) of the sleeve member I34 is bent as at I 42 under the adjacent under surface I I0 of the lug.

In assembling the device shown in Figure 4, each bushing I30 is fitted into one end of the opening I22 with the associated flange I26 bearing against the outer surface I32 of the hub I08. The arm I33 is then bent so that the offset or recess I35 therein snugly engages the inner surface of the hub I08 to afford an interlock therewith. Thereafter, the member I34 is bent from the position shown in dot and dash lines in Figure 6 to the position shown in solid lines therein so as to snugly confine and interlock with the portion I I0 of the journal box lug. One of the wear elements I24 is shown in preassembly position at the top of Figure 4 and the other wear element is shown in final assembled relationship with the journal box lug.

Figure 7 illustrates another modification of my invention, and it may be noted that the construction of the lug I is the same as that in the previous modifications.

The wear member I52 is identical with that shown in Figures 4-6 with the exception that the offset portion of the arm I54, which passes behind the adjacent rib I56 of the lug, has an inturned bottom edge I58 extending into the recess I60 of the lug and clamping the adjacent portion of the lug for thus securing the wear member on the lug and especially securing the portion I62 thereof sheathing the cam faces I64 and I 66 and the rear face I68 of the said lug.

It is to be understood that I do not wish to be limited by the exact embodiments of the device shown which are 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.
