Application filed June 18,

My invention relates to a journal bearing for railway cars and particularly to HHPI'OVGQ means for removing the wedge from the bearing when it is disassembled, V I In my prior Patent No. 1,204,405 of November 14-, 1916, I have shown a form of [special tool. i i

In the accompanying drawings, which i1- l ustrate one form of journal'bearing made vinqaccordancewith my lIlVGIltlOIl, Figure 1 is a vertical longitudinal section through the upper part of a car journalbox; Figure 2 is a section taken 011 the 11ne 22 of Figure 3;

t Figure 3 is an enlargedbottom plan View of the wedge; Figure 4 is a section taken on-the line 4-4 0fFigure 3; and Figure 5 is a sec-- n 1 tion taken on the line'5 -5 of Figure 3.

Referring first to Figure 1, the journal box' indicated at 1 is of the usual type supported on the axle Qby means oftheibrass u and wedges. The wedgemayibe off any suit able conformation but ispreferably Or the general form of the standard M. C. B. wedge so as to be interchangeable therewith. lts

upper face 5 is slightlycurved in ajlongitudinal direction to allow the necessary rocking movement relatlve to theaxle. Longitudinal movement ofthe Wedge relative to the box a is prevented by contact of the front edgeof the wedge'with a lug 6 on the box.

The rear end of thebrass'is provided with an upwardly extending flange? which con tacts with the rearzedge of the wedge and thus holds the front edge of the brass out of contact with a retractile flange on the wedge now to be-described. i

On the front end of the wedge I form a i retractile flange oryhand-hold 8 extending downwardly" and having its lower edge curved on a radius. substantially equal to that of the axle flange 9. By so curving the flange ,81 find tliat'interference with the axle flange avoided and at the sametime evenin the 1 2 s, se iaiasabse; n

smallest size t1": hearings in use on railway c'arss'uflicient area offlange provided to form-Ian efl'e'ctive hand-hold by means of which a workmaiimay In disassembling the parts" of the bearing the box is raisedhy nie anfs of ajack or him ilar device we remove the wei ght of the car from the air Asis well known, the wedge"- will-usually adhere tothebox so as to be raised with it. Owing to the fact that the meme-2 grasp and withdraw the wedge from the bearingbox. V 55,

front end of the brass is prevented the flange 7 from contactingv with the retractile flange 8 of the wedge, thejbrass orat least its forward end will remain in contact with the axle, thus dropping away from the wedge axle flange 9 and the wedge flangeS to allow theworkman to insert his fingers between. these parts and grasp the latter named flange.

The curved form of the upper face of the rocked a sufiicien t distance to permit disengagement ;of its forward edge-from thelug i n In addition to providing ahand-hold for 6 so that it may bewithdrawn from the box.

removing the wedge the curved flange 8 forms brass has reached 1 the limit must be renewed.

Having fully described my invention, what '1 claimns new and desire to secure Let- 'ters Patent of the United States 1s: 1. AWedge for |OL1111L1 bearlngs having at lower face comprisinga central horizontal portion adapted to bear on a brass, said wedge having a part extendlng forwardly of.

said central 1 portion and carrying, hand-hold 1 means positioned laterallyof and below said central portion, said means being spaced from the forward end of the brass when the brass and wedgeare in assembled relation, and being adapted to forma hand-holdforjthe removal of the wedge fromthe journal box,

i 2. .A wedge for journal. bearings comprisand so providing suflicientspace betweenthe wedge allows of the wedge being readily an accurate gauge fordetermining when the IlZSiWGZU. and i i ing a body portion providedon its under side 1 i with a horizontal bearing face'andla pair of i downwardly;projecting side portions adaptedto cooperate with abrass, saidside por- .tions being provided with recessed forward extensions, the forward walls of said recesses extending below the horizontal bearing face and being spaced from the forward end of the brass when the brass and wedge are in assembled relation, and adapted to form hand-holds for the removal of the wedge from the journal box.

3. A wedge for journal bearings comprising a body portion provided on its under side with a horizontal bearing face to cooperate with a brass and a pair of downwardly projecting side portions each provided with an inclined bearing face, said wedge being provided with a pocket at the front ends of the bearing faces, said pocket extending into the side portions of the wedge, the front wall of said pocket forming a flange connected with both the body and the side portions of the wedge and providing a pair of lateral hand-holds approximately triangular in shape and spaced from the brass when the brass and wedge are in assembled relation.

In testimony whereof, I hereunto aflix my signature, this 14th day of June, 1928.
