In use, when it is desired to remove the device from the axle-box 8, the springleaves 5 are flattened by pressing on the finger plates afforded by the members 9, thus bringing the pad into the position shown in Figure 4, and allowing the device to be drawn out by means of hooked portions of the members 6 without fouling the fillet 4? of the axle journal 4:.

In order to allow free movement of the spring leaves 5 the pad 1 is made in two parts the arrangement being such as to leave a space 14 which allows the journal at to be lubricated by oil splashing from the bottom of the axle-box 3, and although two longitudinal connecting members 8, 9 are shown between each pair of spring leaves 5 the lower of these may be dispensed with and the upper one 8 be provided with an extension to afiord finger plates.

I claim 1. A supporting structure for a lubricating pad for a. railway axle, said structure comprising a lower rectangular frame and an upper pad carrying frame and a resilient" connection therebetween, said upper frame com risin an elon ated member the D i D 7 longitudinal axis of which is disposed substantiallyparallel to and at one side of a vertical axial plane of said axle, said lower rectangular frame comprising two elongated inembersdisposed on opposite sides of said vertical axial plane, said resilient connection b'etween said frames comprising a leaf ing pad' for-a V stantially rigid, rectangular lower frame;

spring fixed adjacent its ends respectively to said upper elongated member and one of said lower elongated members of said upper and lower frames, said leaf spring extending through said vertical axial plane and being adapted to urge said upper pad carrying frame into operative relation to said axle.

2. A supporting structure for a lubricatrailway car axle in a journal box, said structure comprising a suba plurality ofupper pad carrying bars disposed on opposite sides of a vertical axial plane'of said axle, and a resilient supporting connection frame,- said connection comprising crossed spring members extending from said bars Y to said frame at opposite sidesof said vering pad for a railway tical axial plane, and means operable to depress said bars against the action of said resilient connection, whereby said supporting structure may be distorted in shape to facilitate its removal from said journal box.

3. A supporting structure fora lubricatbox, said structure comprising a substantially rigid rectangular lower frame, a plujeinedby' strips l of flexible material,

between said bars and said permit removal of said structure from said car axle in a journal rigid the action of said spring members, whereby said supporting structure may be distorted in shape to facilitate its removal from said journal box. i

, 4. A supporting structure for a lubricating pad for a railway axle in a journal box,

said structure comprising a substantially rigid rectangular lower frame, upper pad carrying means, and a resilient connection therebetween, said lower frame comprising longitudinal side members and transverse end members fixedly connected together at the frame corners, said pad carrying means comprising a pair of bars, each disposed on oppositesides of a vertical axial plane of said axle, said resilient connection comprising oppositely extending crossed spring members disposed between each bar of said pair of bars and the longitudinal side 'mem her on the opposite side of said vertical 9 axial plane, and means operable to flex said spring members to permit removal of said supporting structure from said journal box.

5. A supporting structure for a lubricata ing pad for a railway axle in a journal box, 1 said structure comprising a rectangular lower frame, upper pad carrying means, and

deformable connecting means therebetween, said lower frame member comprising longitudinal side members, transverse en'dmem 1 bers, and an upstanding bracket on one of said end members, said pad carrying means comprising a longitudinally extending bar disposed'on each side of a'vertical plane ofsaidaxle and a forwardly projecting extension on each of said bars, said deformable connection comprising oppositely extending crossed spring members disposed betweensaid bars and said longitudinal side members on respectively opposite sides of said vertical axial plane of said axle, said deformable means-also comprising a laterally extending'arm rigidly secured to each Sfild extension on said'bars and fulcrumed at its OPPOSitQQIKl Unsaid pstanding brack et on said lower frame member, said extensions, arms, and brackets comprising means for flexing said spring members to journal box.

,6. A supporting structure for a lubricating pad for a railway axle in a journal box, said structure comprising a substantially rectangular lower frame, upper pad carrying means and deformable connecting means therebetween, said lower frame haw mg an upstanding bracket at one end thereof, said upper pad carrying means having forwardly projecting extensions disposed on opposite sides of a Vertical axial plane of said axle, said deformable connection comprising crossed spring members disposed between said rectangular lower frame and said pad carrying means and a laterally extending arm rigidly secured to each of said forwardly projecting extensions and fulcrumed upon said upstanding bracket, said extensions, arms, and bracket comprising means for flexing said spring members to permit removal of said structure from said journal box.
