This invention relates to lubricators for locomotive driving boxes, particularly to that type which includes a lubricant cellar of a width substantially less than the diameter of 5 the journal or the distance between the box,

legs. Y v

This particular type of lubricator is more ecient in the use of the grease or lubricant, than the type which provides for the use of a grease cake of substantially the same width as the diameter oi' the journal. The larger grease cake, with its extended upper surface contacting with the journal, is fed to the 'journal relatively slowly and hence its lubrieating qualities deteriorate, at times, to anv extent which impairs the lubrication of the journal before the cake is ventirely used up. In order to maintain proper lubrication of the journal the calzeV must, therefore, be renewed before it is entirely used up. Y The smaller grease cake, .withv its relatively small surface'contacting with the journal, is fed to the journal more rapidly.l Theuse of a smaller cake thus eliminates waste but it also presents the problem of providing pro- .tection, particularly from dirt, for those portions of the journal which contact with and are protected by the extended surface of the larger calze.

The primary objects of the present invention are to provide means for effectively protecting the journal between the sides of the grease cake and the box legs and to provide' means whichwill automatically advance the protecting meansV as wear occurs in the bearing brassso that the protecting means will remain adjacent the journal at Vall times.

`More specilically I provide a lubricant cOn-.

tainer or cellar having outwardly extending flanges secured to the top edges of its side 'j walls, said langesand cellarbeing supported by the grease cake.

, How the foregoing together with other ob- Vjects. and advantages are obtained will be clear from the following description considered in connection with the accompanying drawings, wherein, l 4 Fig. 1 is atront view, half in elevation and half in section of a locomotive driving box @mb0dring1-myimrrovemen reactants-1 ingtakenonithelne flr'foffFgQ i i j Eig;2-is\,a5longitudinalsectional `ievvfti'tlfe'n en ftheifline EZ- 2" o'fFigJ, l, the journal fleeing omitted g j 1, if; is Referring new toit-he drawing; the #refereneenumeral sndeates thejeurnalande i thelegs-ofthe drivngbex. 1 spreader men-1L ber indicated as a whole bythe reference ynur-iV merall-is positioned betweenthel box legs.
