To all whom it may concern.-

Be it known that I, BURTON R. STARE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement viding for jacking up the journal-boxwith relation to the journal when needful for repairs or renewal of parts. The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents a longitudinal sectional viewof the journal-box of a car with the journal in place and equipped with my improve-' ments; Fig. '2, a horizontal section taken as indicated at'line 2 of Fig. 1, the journal being removed; Fig. 3, a section taken as indicated at line 3 of Fig. Land Fig. 4 an enlarged section vtaken as indicated at line 4 of Fig. 3 and showing a detailof the universal.

connection employed between the roller-frame and its support.

A represents a j ournal-box of the ordinary construction equipped with a brass hearing A, a wedge A and a dust-guard A B, a journal of the usual construction provided at its free extremity with an annular flange B; C O, oiling devices serving to supply oil to the journal; D, a lug projecting upwardly from thecentral outer portion of the bottom of the journal-box and having its upper end located directly beneath the flange B; 'E, lugs with which the inner surface of the bot tom of the journal-box is equipped at a con-- tral transverse plane and which afiord between them a transverse channel receiving an oil-guard E, and E an oil-guard projecting inwardlyfrom the upper edge ofthe lower portion of the inner wall of the dust-guard cavity.

Each of the devices 0 0' comprises ashort inclined roller-frame a, with suitably-spaced side members a and connecting end members a a", a roller 1 antifrictionally ournaled on a shaft (i having angular ends fititing within sockets, with which the side members of the frame are provided centrally at their upper edges, a horizontally-disposed frame-supporting hook or stud a having screw connection with one side of the journal-box a short distance above the bottom of the box and having universal connection with the end a ofthe roller-frame, a spring 01?, connected with the free end of the rollerframe, and a spring-supporting stud or book a having screw connection with the opposite 'wall of the journal-box in the same transverse plane as the hook a tion of the member a is of a width enabling The hook porit to fit loosely between the side members of the roller-frame and embrace the end member a Said hook portion is provided centrally with a concavity 17, extending 1ongitudinally'ofthe hook 'and following the contour thereof. .The end member a is of substantially circular cross-section, with a flange b at its upper portion extending longitudinally of the end member. The end 'member is provided on its sides and lower portion centrally with a circumferential convexity 17 which fits in the concavity 6. Thus theframe a iscapable of swinging in a trans-- verse vertical plane, the flange b working in the space 19 between the extremity of the hook and the shank of the hook, and also the frame is capable of swinging in a longitudinal plane about the hearing I) 19 within limits. Thus the frame has practically a universal movement within limits and yet is socurely held upon its support. The spring serves to hold the lubricating-roller firmly against the journal.

From Fig. 2 it will be understood that the oiling devices 0 G are arranged in different transverse planes, and from Fig. 3 it will be understood that the lubricating-rollers of the two oiling devices are located on opposite sides of the journal and journaled in their frame some distance below the universal supports of the frames. Each frame being short and virtually depending from its support enables the necessary movement of the lubricating-roller to occur when it is necessary to jack up the body of the car or lift it from the trucks for purposes of repair or for other purposes. The springs hold the lubricatingrollers firmly in contact with the journal, and as the bearing A wears the roller-frames are drawn upwardly. The extreme Wear on the bearing A, which is permissible, is indicated by the dotted lines in Fig. 3, and the upper dotted-positions of the rollers a indicate their position after such wear has occurred. The lower dotted positions of the rollers indicate the positions to which they are capable of swinging when the journalbox is raised with relation to the journal, and the lower dotted position of the journal indicates its lowest possible position with relation to the journal-box, the lug D in this position serving to support the journal and prevent crushing of the rollers.

The lug D has its top separated from the flange B of the journal by a space 0, which should be short enough to cause the flange to engage the lug before a crushing pressure can be brought upon the rollers.

The oil-guard E comprises, preferably, a sheet-metal member folded upon itself, the folded margin being inserted between the lugs E and the upper edges being bent away from each other to afford the flanges. The oil-guard E is preferably formed integrally with the inner wall of the dust-guard cavity and has a curvature corresponding with the curvature of the journal-opening. To permit the journal-box to tilt somewhat with relation to the journal in a longitudinal plane, the inner wall 01 of the dust-guard cavity is cut away below the outer wall d of said cavity at the lower portion of the dustguard cavity.

It will be understood that the universal connections of the roller-frames permit the rollers to adjust themselves with relation to the journal, rendering the frames self-righting, so that the rollers maintain line-contact with the journal. The feature of the upper edge of the lower portion of the inner wall of the dust-guard cavity terminating beneath the upper edge of the lowerportion of the outer cavity provides for a return to the journalbox of any oil which may accumulate in the cavity. The oil-guard E effectually prevents the loss of oil by splashing, as when the car is rounding a curve.

In the construction shown the roller-frame supports have screw connection with the side walls of the journal-box, as do the springsupports. This enables the oiling devices to be applied to journal-boxes already in use. It will be understood, however, that the supports for the roller-frames may be arranged in any suitable manner without departure from my invention. It further will be understood that other changes in details of construction within the spirit of my invention may be made. Hence no undue limitation should be understood from the foregoing detailed description, which has been given for clearness of understanding only.

What I regard as new, and desire to secure by Letters Patent, is

l. The combination with the journal-box and journal of a car, of a stud within said journal-box and having threaded connection with a wall thereof, a short roller-frame movably supported directly thereon having both a self-righting and a wearcompensating movement with relation to said stud, a lubricating-roller journaled on said frame, and means for yieldingly holding the frame to cause the roller to bear against the journal, for-the purpose set forth.

2.- The combination with the journal-box and journal of a car, of a stud within said journal-box and having threaded connection with a wall thereof, a short transversely-extending roller-frame having one end supported directly thereby, said frame being capable of a self-righting and a wear-compen satingmovement, a suitably-sustained spring connected with the free end portion of said roller-frame, and a lubricating-roller journaled on said frame, for the purpose set forth.
