elements of the locomotive; my improved liner therefore being designed to obviate the rather laborious and expensive practice at present employed when removal of the hub liners are necessary.

Ihe above enumerated advantages and objects, as well as other advantages inherent in the invention, will all be'more readily comprehended from the detailed description of the drawing, wherein Figure 1 is a side elevation of a portion of the front or engine truck end of a locomotivc, showing in dotted lines, one form of my invention applied to the journal-boxes.

Figure 6 is a perspective view of the form of hub liner employed in Figure 5. V

In the exemplification of the invention as shown in the first four figures of the drawing, my improved hub liner is shown in a form more especially adapted to the journal or driving box of the engine trucks and to boxes employing cellar bolts; although the liner shown may be slightly modified to adapt it to any of the well known types of journal boxes employed.

Hub liners as heretofore constructed and employed have either been cast or riveted on the faceof the driving box, or secured in place by screw-plugs, the heads whereof are countersunk in theliners andthe plugs screwed into tapped holes in the face of the journal box at points directly opposite to the hub of the wheel. ed as just described, it has been impossible to apply such liners or to replace the same while the wheels and journal boxes are in assembled relation; and as a result it has been necessary to place the locomotive ,over a drop pit" and to lower the wheels and b h d 't 'b ournal oxes into t e rop p1 or y some means lift the locomotive oil the wheels in order to provide access to the hub faces of the journal boxes for the purpose of applying or replacing the hub liner plates. As is apparent, such operation is quite expen sive because of the time requiredd uring which time the locomotive is held out of scrviceand on account of thelabor and number of men required to do the work.

My improved liners are of such construe tion that they can be easily and quickly applied by one man without disturbing or dismantling any part of the locomotive and t1 ercfore without the loss of time heretofore encountered, as my improved liners can be put into place in the'period of time usual fora locomotive to remain at a terminal between runs.

In the construction shown in the first four figures, the liner shown at 10 consists of a suitable sized metal plate of proper thick ness and cut out from the bottom edge as at 11 to fit over and receive the journal 12, to which the wheel 13 is secured; The outer perimeter of the liner-may be of any suitable configuration and the plate at top is provided with rearwardly disposed lugs 14, 14, each provided with a bolt-receiving opening 15. These lugs 14, 14: are adapted to lap over the top of the j ournal-box 16, which is provided with suitable tapped holes to receive the tap-bolts 17, 17, see Figure 3, whichextend through holes 15 in the lugs 14 of the liner and'securely fasten the latter in place intermediate of the forward face of the driving or journal box 16 and the rear face of the hub of the wheel 1.3, see Figure 2.

The lower ends of the two legs or side portions of the liner plate 10 are each pro vided with a lug 18, disposed rearwardly from the outer edge of said side portions and adjacent to the lower edge of the liner,

With liners constructsee Figure 4. These lugs 18, 18 are intended to overlap the sides of the journal box 16; and each lug 18 is provided with an opening 19, intended to receive the outer cellar pin 20, of the journal box 16; the pin being of the usual construction and shown held in place by cotter-pins 21.

The liner plate on its top, intermediate of the lugs 14, 14, is provided with a rearwardly disposed boss 22 of proper thickness to provide a cavity or pocket '23, open at top toreceive a suitable lubricating medium. The bottom of the cavity or pocket 23, at the forward side is provided with a forward- .ly slanting hole 2% (see Figure 2) which terminates on the front face of the plate 10; the latter being preferably provided with the downwardly diverging grooves or chan- I1els;25. The cavity or pocket 23 in the boss 22 is filled with a suitable liquid or semi liquid lubricating medium, which finds its way through the hole 24 and into the grooves 25 whichcause the lubricant to be distributed andspread on the outer surface of the liner plate 10 and therefore onto the hub surface which is adjacent to the liner plate 10,,causing the opposing surfaces of the liner 1O andthe hub of the Wheel to be thorough ly lubricated. The boss 22 is arranged so as to extend over, the top of the journal box as shown in, Figure 2 and thus assists in holding the liner in place.

It is apparent from the construction shown. that my improved liner may oe easily dropped down into place by passing the openended slot or cut-out portion down over the journal 12, between the front surface of the journahbox 16 and the rear face of the wheel-hub and the liner secured in place by the tap-bolts 17 and the cellar pin 2.0, which are all arranged at points where they are easily accessiblewithout the, necessity of removingor disturbing any ofthe surrounding parts of. the locomotive. Furthermore, with my improved construction, the liner 10 is not dependent upon the tap-bolts 1'? or,

the cellar pin or boltsforsecuring it in place, as it cannotget out of place even if these bolts should become loosened or be removed, as the lugs 14 and 18 will maintain the liner in position. W ith my improved liner, there are no screw-plugs in the wearing face ofthe liner where they are apt to be sheared off and therefore no plug holes in the liner face to cause breakage of the liners, as is the case with liners as at present in use.

In Figures 5 and 6 I illustrate modified form of my improved liner which is especially adapted for use on the trailer trucks of a locomotive. The liner shown at 26, like liner 10, is made of a suitable sized metallic plate provided with a cut-out portion 27 open at the lower edge of the plate 26 so as to permit the liner to be slipped down over the j ournal'12, between the inner faceor side of the track frame and the outer surface of the Wheel-hub; the cut-out portion 27 being of any suitable configuration to conform with the adjacent portions of the journal box portion which in this instance is made as an integral part of the truck frame.

The liner plate 26 is shown provided with laterally disposed projections or lugs 28, 28, extending, by preference, from the sides adjacent to the top of the plate and to a suitable distance and'with the laterally disposed projections or lugs 29, adjacent to the lower edge of the liner plate; all of the lugs being preferably somewhat enlarged at the ends. for purposes of reenforccment and to adaptthem to the off-set surfaces ad jacent to the journal bearing portion on the inner surfaces of the truck frame; the lugs being apertured, as at 80, for the passage of bolts 31, which also pass through reamed holes in the side walls of the journal-box portion of the truck frame. The lugs 28 and 29, formed as shown, bring the bolt receiving holes beyondthe hub ofthe wheel and therefore at points where they are easily accessible without necessitating removal of any other part of the locomotive.

he liner plate 26, shown in Figures 5 and 6, is provided adjacent to the top with a port or oil hole 32. which communicates with a cavity or pocket shown in dotted lines at 33 in the upper part of the journal box portion of the truck frame. With the cavity 33 filled with. a suitable lubricant the lubricant will pass from the cavity through the hole 32 and flow over the surface of the liner which contacts with the hub of the wheel.

Both forms of my improved liner are easily put into place and take up the objectionable lateral play which results from the wear on the face of the wheel hub and the face of the journal box or journal box portion of the truck frame which bears against the wheel hub; these faceswearing more rapidly in territory where the track has, sharp and frequent curves, which necessitates frequentreplacement.

As the liner is intended to provide a facing between the wheel hubs and the adjacent faces of the truck frame or journal boxes and therefore are intended to practically cover the entire opposing face of'the hub .to take up wear, it is essentialto provide a smooth unbroken surface between the peripheral edges of'the plate, that is to say a continuous or integral surface not interrupted by boltsheads, as the latter are apt to become loosened and sheared off. With either form of my invention, a continuous, smooth wearing surface for substantially the entire opposing face of the wheel hub is provided, while the means for fastening the liners in place are disposed beyond the periphery of the wheel-hub where no contact with the wheel-hub can be had and where at the same time said means are easily accessible without necessitating removal of the trucks or any portions thereof.

I have shown specific formsof my improved liner adapted to the journal boxes and the journal box portions of engine trucks and trailer trucks, but it is evident that with suitable modifications, either of the liners shown could be applied to the front trucks, or to the driving or trailer boxes of a locomotive; the forms shown having been described in terms employed merely as terms of description and not as terms of limitation, as modifications may be made without, however, departing from the spirit of my invention.

What I claim is A journal box hub liner comprising a flat plate cut out from the bottom edge to lit 1 about the journal, with the top of the plate provided with a rearwardly ofifset boss having a lubricant holding cavity and a passage from the bottom of said cavity toward the front face of the plate and terminating on the front face of the plate in a pairof downwardly diverging grooves, the upper and side edges of the plate being provided with lugs, the lugs on the upper edge being arranged on opposite sides of the boss,all of said lugs being apertured and disposed rearwardly parallel with the journal to engage with the journal box.
