i invention relates'to railroad rolling stock and consists lnfan nnproved lubricatlng device for car or locomotive ournals.

In such journals, it is customary to dis- ;tribute lubricant over the journal face by means of-capillary attraction produced by packing the journal with cotton waste and supplying lubricant to the waste. The waste is sometimes saturated with lubricant at intervals and devices have been proposed tor lubricant to the waste from a reservoir located below the same and for supply lubricant from a reservoir above the journal. Each of these methods are open to i objections,

re-oiling at intervals and the journal and Figure 11 1 re -t e v t Qp s' 1 ,1 In the construction shown 111 Figures 1 and r I will avoid lossofsurplus 'slaine time keep the waste saturated'to the ;-bearing are damaged it this is neglected. Thesecond method involves expensive workingp arts' not always reliable. The third =method, so far asI am aware, usually produces anbVer-supply of-lubricant, resulting .i'nwaste of thesame, v

isutilized, calls for manual operation of f thesame at intervals, which operation may or, if a supply "valve be neglected. v

L [The object of present invention is to provide a lubricant reservoir adapted to feed r lubricant by gravity to the cotton waste,r but [equipped wi h automatic meansfor maintaining the lubricant at a constant level which lubricant and at the desired degree. v

The plug 8 is provided with a screen S and has a passage the wall of which is shaped to form a valveseat 12 [and a-valve 13 is positioned in said passage and normally" held. against its seat by: a lever. 14 pivoted at 15 on legs .8 extending downwardly from the plug 8 The longer arm of the lever lfliis supported-by afloat 16 floating in the voil in cellar 5, the normal oil level being indicated bythe dot and dash lineC, The float 116 may be of any bouyant material or may be a hollow vessel ofsheet metal or the'lilre;

A bolt 17, inserted through'the lower wall ot' the cellar and secu 'ed.inposition' by a nut erves to position these members 18, passes throughlever 14: and floatlfi and.

Whenthe. ,oil' level falls below. the inwhioh'it affords sufiicient buoyancy to the float to hold valve 13' against its seatrthe weight of the leverlfi- Willraise the-valveand permit oil to fiowirorn the reservoir through I plug 8 into the cellar. The float and lever rising with the oil level closes the valvethus limiting the amount of oil in the cellar.

It is'desirable to prevent the opening and closing of the valve by slight=variation in the height of the float. Such valvefloperationis prevented by the pin and slot connection vbetweenthe lever and valveand by use of a spring 19 compressed betwee na projection 1 1 on lever lt and a pin 20. carried by plug leg-s8. 1H A rod 22 is pivoted to projection 14? and extendsthrough p 1n The upper endot the 'ing portion otthebox'. The lowerportion .onto plug 8 serves lto clamp the reservoir tightly to the b oxwall. suitable gasketsg 10 lever, and means mounted on said leg for yieldingly' holding said lever in position.
