This invention relates to appliances of the general class or type known as hub liners, which are'interposed between the journal boxesof railroad vehicles and the wheel hubs 5 adjoining them, for the purpose of absorbing lateral pressure in passing around curves. The type referred to is instanced in Letters Patent of the United. States No. 1,551,005, granted and issued to James G. Blunt, under 10 date of August 25, 1925, upon which the present invention is an improvement.

The ob 'ect of the invention is to provide a hub liner having the'operative advantages of that set forth in Patent No. 1,551,005 15 aforesaid, and in addition, the structural advantage of capability of application in connection with journal boxes of such form as would preclude the applicability of the hub liner of said patent,

The "improvement claimed is hereinafter fully set forth. z In the accompanying drawing: Figure 1 is a vertical axial section, through a journal box and wheel hub, illustrating an application of the invention in connection therewith; Fig. 2, a side view, in elevation,*of the hub liner Fig. 3, a plan or top view thereof; and, Fig. 4,'a perspective view, on an enlargedscale. i In.the practice of the invention, referring descriptively to the specific embodimentthereof which is herein exemplified, a wear plate or liner isinterposed between the outer end of. ai journal box, 1, and the hub of the adjacent wheel, 4, said liner being'of sectional construction, and comprising 'two members or sections, 2, and 2*. The section, 2, is in general inverted L form, as seen in side elevation, and the section, 2 is'in-gen eral rectangular form when similarly viewed. The two sections abut, one against the other, at one end of the horizontal limb of the section, 2, and are detachably connected by a 0 bolt, 3, passing through bolting lugs, 2*, one on the top of the horizontal memberof the section, 2, at the abutting end thereof, and theother on the top of the section, 2". The bolt, 3,is drawn toa tight bearing by a nut, 3'. I

The sections, 2 and 2?, when connected to form the complete hubiliner, are supported on the top of thejournalbox, a bearing face, 2 "of proper form, being providedon V the lower sideof thetop member offth'e isection, 2, to fit over thebox.

An open topped oil recess, 2, is formed; on

the top member of thesection, 2,;atthejend thereofffurther from the section, 2 said oil recess communicating with oiling grooves, 2, in. the faces of 'the "sections adjoining the inclined dovetailed tongue, 2 is :formed on each of'the sections "of the 'hub liner,fs,aid. tongues being adapted'to fitinjsimilar grooves in the outer-facev of the journal box.- The oil recess, oiling grooves,and tongues,.'are substantially similar to the corresponding members ofthe'hub liner of Patent No. 1,551,005 aforesaid, and do not form partof the present invention.

. It will be obvious wheel hub., Aninwardly a'nddownwardly to those familiarlwith,

:the construction of railroad rolling stock,

that the inventionherein'setforth is of sub stantial practical value, in' the capability which it affords of application in connection with journalboxes'of several types 'now in service, in which the space above the connecting bolt is so limited as to render it difficult,

if not impossible, to obtain access to the nut of the connecting bolt, when the hub liner comprises counterpart sections abutting in the vertical axial plane of the journal box.

The invention claimed as new and desired to be secured by'Letters Patent is I 1. Ahub liner composed oftwo sections, adapted to abut one against the other, one of said sections being of substantially inverted L form, and the other of substantially rectangular form, the first specified section having a bolting lug .on the abutting end'of its horizontal member, and the second specifiedlsection having a corresponding bolting lug at its 'top and means for connecting thes'ectmns through the bolting lugs. i

2. A hub liner composed of two sections,

adapted to abut one against the other, one

of said sections; being of substantially invertedL form and the other of substantially.

its horizontal member, and the second speciing a bolting lug on its abutting side, and an.

inclined tongue adapted to fit in a groove in the end face of the journal box a connecting bolt, passing through, the bolting lugs; and a nut, engaging said bolt to secure the sections in place.

4. A hub liner composed of two; sections, having top faces oppositely disposed, one of said sections being of substantially inverted L-shape, and the other of substantially rectangular f0rm,thefirst specified section having a bolting lug on its horizontal member adjacent its said top face, and the second specie l ct on i g ol ng g opr site i first mentioned bolting lug, said horizontal member having a lower Wall for supporting the liner upon the box, oil grooves in the Wheel opposed faces of the sections, a groove of one section registering with a groove of another section, an oil receiving recess onthe end of the liner opposite. the lugs, said oil recess being in communication" With the grooves, and a bolt engaging the lugs for bolting the sections together to support the rectangular section against vertical displacement and to maintain said registry of the oil grooves.
