Figures 4 to 7, inclusive, illustrate a modified ;form :of :the invention-inwhich the -,portion .of :t-he =j.ournal inside the journal box ,is provided with a tooth-like projection .39.. i'lihezinnfli wvallafi complished with the H 1 constant engagement 55 2 of the cellar 32 is provided with a bearing 42 mounting a shaft 33 which carries on its end inside the cellar a cam 34 and on its other end a star wheel 35. Lever 36, pivoted intermediate its ends to an upright element 43 on the floor of the cellar, slidingly engages the face of the cam 34 at one end and is yieldingly connected at the opposite end by means of 41 to the middle of the pad supporting pan 3'7. The lever is shown perforated at 'to' accommodate spring 44a which cooperates with spring 44 in maintaining the oil pad normally in engagement with the journal. 7

As the journal rotates in either-direction in its bearings, the tooth projection 39 engages the star wheel 35 and causes the same and the cam 34 to rotate. As lever 36 is engaged by the high portion 34b of cam 34, pan 3''! and oil'pad 38 will be drawn away from the journal against spring ,44 and 44a and asthe lever engages the low portion 34a of, the cam,the springs 44 will cause the pad to forcefully contact with the journal, squeezing out a portion of the absorbed oil, the pad remaining momentarily pressed against the journal to insure adequate lubrication.

In both forms of the invention a predetermined "level of the lubricant is constantly maintained in the reservoir by external means, notshown,

and is such that when the open-work pan is in its; lowest position, the oil pad will be at least partly immersed in the lubricant, thus providing for saturation of the pad at all times. 'In the highest position of the pan,"the pad ispressed against the journal causing lubricant to be discharged thereto. Preferably, the pan support- 1 ing springs will be of sufiicient strength to cause the pad inits upward movement to slap against the journal, squeezing o t a portion of the absorbed oil, thus assuring immediate and adequate lubrication. Or these springs may be just strong enough to support the weight of the pan and pad,- the lever mechanism serving to raise as well as lower the pan and pad.

7 It is apparent that in either of the above forms of the invention wherein either the lateral or rotational movement of the journal is utilized to alternately "dip the pad in the supply of lubricant and press the soaked pad upwardly against the journal, positive lubrication of the journal is acuse of a minimum number of moving parts requiring practically no maintenance or repair. Moreover, the life of the pad 4 wherein a is prolonged over previous arrangements 7 of a lubricating pad with the journal surface is maintained since the tendency to cake along the bearing surface of the pad is practically obviated and the pad is kept thoroughly saturated at all times. Also, more effective lubrication of plished than has heretofore been possible. case of damage to the the oil-soaked pad will nal continuing period. V 7

While integral structures'have been illustrated be held against the jourthe lubrication for a substantial wherever possible because the consequent inl V durability and decreased weight, such partsmay be asembled by suitable meansfwhere desired. Obviously the various creased strength and parts may be varied as to shape and size and may be otherwise modified without departing from the spirit of the invention and the exclusive use of the novel features disclosed herein and expressed in the appended claimsis contempl ated,'
