bINING- FOR JOURNAL-BOXES.

Specification' of Letters Patent.

Patented Nov. 14, 1916.

Application mea April as, i916. serial No. 94,222.

To all whom it may concern Be it known that \ve,.VV1LLrA1\r K. LYNN and VALTER T. VEAVER, citizens of the UnitedStates, both residing at Gulfport,

in the county of Harrison and State of Mississippi, have invented certa-in new and useful Improvements in Linings for Journal-Boxes, of which the following is a speciication, reference being had therein to the accompanying drawing.

This invention relates to improvementsA in liners adapted for use in connection with 'journal' boxes to take up the wear between the face of the .journal-box and wheel.

The primary object of the invention is the hub of the provision `of a liner lpossessing improved attaching means coperating' with complemental parts on the journal box for enabling ready attachment or detachment of the liner relative to its operative position between the end of the `journal box andthe hub of the adjacent wheel. Heretofore in this art in order to take up thewear to which we have alluded, it was originally necessary to remove Aor drop vthe wheels and associated parts, enabling the' substitutionof a new journal box or'the fastening of a supplemental rail plate thereon, but to overcome this disadvantage manv attempts have of late been made to provide a liner capable of yse -box presenting .angular being attached to the journal box without the expense. and delay of removing any of the parts of the locomotive or vehicle, but in each instance so far as we are advised the interlocking. means provided between the journalv box and' liner or plate has either been of a relatively loose engagement ne cessitating supplemental fastenings, or in wedge engagement on the end of the journal exposed to breakage.

Our present improvement overcomes the disadvantageous characteristics just noted in that the same contemplate a liner having lthe whole of its outer face capable of a uniform, flat Contact with thel abutting face of the end of the journal box, and securing means at the 'sides of the journal box for wedging the liner in a ixed relation to the .jo .rnal box by drawing said outer face of the liner firmly against the face of the end of the box, so that any impact or shock against the ,inn'er face of the liner is distributed over a Wide area approximately (5o-extensive with.

edges, ribs or lugs,

the size of the liner itself and from the liner to the body of the-journal box.

To facilitate an understanding of tlie invention we will illustrate in the accompany- 'ing drawings forming part hereof the preferred embodiment ofthe invention, the improved details in construction and arrangement of the several parts thereofbeing readily understood fromthe specific-'description hereinafter contained when read in connection with said drawings.

In the drawings: Figure 1 is a topv view of a journal box with our improved liner attachedthereto; Fig. 2 is an inner face view. of the liner in position, as indicated in Fig.A

' inner walls of the grooves, represented at E,

incline downwardly and outwardly constituting wedging surfaces, as will be apparent.

' F is the detachable liner, -the same havingV flat inner. and outer surfaces, the latter corresponding to the inner end or face D of the journal boxso as t'o occupy. parallel relaer face ofthe journal box, alined tion thereto andito have a flat even engagevment therewith throughout the extent-of the plate, the opposite vertical side edges of the liner having upwardly extending anges G, spaced a suitable distance apart to slide vertically over the side edges of the journal box, the outer edges of the flanges terminating in inwardly turned wedge parts H, the faces J and K ofwhicha're parallel to each other but inclined downwardly and out w-ardly with reference to the liner F, to be complemental to and coperate with the wedging surfaces 'E of the grooves in the sides of the journal box. Of course it is not necessary that the outer faces J ofthe wedge parts be inclined, so long as the proportions.

are such that there is a space L always pre- .served between the same and' the vertical wall C of the groove B, so that no impact can take place between the wedge parts and the wall C of the groove, which might tend to break vor fracture the same under the pressure or binding encounter of .working conditions. i"

From the foregoing description it will be understood that the liner being dropped into place rfrom the top of the journal box with the wedge parts F traversing downwardly, the groove C, the cooperating, wedge'surfaces E and K will draw the liner F up into an impinging rela-tion to the end D of the journal box and constitute the whole a rigid structure capablexof distributing the strains of impact or other shock throughout the liner and from the liner to and throughout the journal box, as previously observed, and so without undue respect a set screw M is provided, the same strains upon the securing langes and wedge parts carried thereby,

rlhe driving of the liner home will create sullicient friction between the opposing faces of the journal boxY and the linerV and between the wedging surfacesto ordinarily maintain the liner in operating position intermediate of the journal box and the a-dja cent wheel, but vas additional security in this having threaded engagement with one of the flanges G of the liner so as to be carried by the latter and be adapted to Screw into a recess m in the side of the journal box to interlock the parts together.

While We have herein illustrated a par ticular embodiment of the invention, it will be understood by persons skilledin the art i to which the invention pertains that changes parts acting to draw the liner toward and into impinging relation to the adjacent face of the end of thejournal box.

2. The combination with a journal bo'x,`

of a liner therefor, said journal box and lining having cooperating means for securing the liner to the journal box including parts acting to dravsT the liner toward and intov impinging' relation to the adjacent face of the end of the journal box, the contacting surfaces of the liner and journal box being of an area substantially co-extensive with the size of the liner.

3. The combination with a journal box, of a liner having its inner face formed to Acontact with the adjacent end of the journal box, said journal box and lining having cooperating means for securing the liner against the face of said end including wedging parts at the sides of the journal box receding outwardly toward the bottom of the box to incline away from said face, and cooperating edges on the liner.

4. The combination with a journal box, of a'liner therefor, said journal box and liningl having cooperating means for securing the liner to the journal boX including parts acting to draw the liner into impinging relation to the adjacent end of the journal box, the contacting surfaces of the liner and journal box being of an area substantially co-extensive with the size of `tlieliner, those portions of -the sides of the journal box and edges of the liner opposite the wedging surfaces being removed with reference to each other to prevent engagement therebetween, substantially as described.

5. The combination with a journal box, of a liner for one end of the same, said j ournal box and liner having cooperating wedge parts for securingthe liner to the journal box, said wedge parts being located at the sides of the journal box and adjacent side edges of the liner and acting to draw the liner toward the face of the end of the box.

.6. The combination with a journal box, of a liner for one end of the'same, said jour nal box and liner'having cooperating wedge parts for securing the liner to the journal box, said wedge parts being. located. at the sides of the journal box and adjacent side edges of the liner and acting to draw the liner toward the face of the end of the box, and interlocking means between one of the edgeA portions of the liner and the adjacent side of the journal box.

ln testimony whereof we hereunto afiix our signatures in the presence of two witnesses..
