Application filed September My invention relates to lubricators adapted to be used in connection with railway rolling stock and consisting in improvements upon the lubricators of the type illustrated in my prior Patent No. 1,412,741, and my copending application Serial No. 7 42,253, in which the pumping mechanism is operated by movement ot the journal to and fro in the driving box.

One object oimy present invention is to provide a lubricator of this type in which the lubricant pump may be easily removed from the cellar without disassembly oit' the cellar from the journal to which itis applied.

Another object of my invention is to provide a yielding support for the waste containing sub-cellar which will *facilitate the insertion of the sub-cellar in the cellar when the latter is assembled with the driving box.

An additional object of my invention is to provide in a lubricant pump of the type used in my lubricator, means for preventing undesirable rotation oi: the pump parts and corresponding departure otx the same from a desired position relative to the vertical.

A further object of my invention is to so construct a lubricator with lubricant reservoir that lling of the latter will not -flood the lubricator.

Another objecto my invention is to provide improved means for preventing the waste of lubricant by the centrifugal discharge of the same from the surface of the journal being lubricated.

Another object of my invention is to construct a lubricating cellar of the type referred to which may be applied to diHerent driving boxes in which the cellar pin holes are located at different distances from the normal position or the journal to be lubricated, thereby avoiding a different cellar construction for every variety of driving box.

In the accompanying drawings which illustrate a selected embodiment oi' my invention Figure 1 is a vertical longitudinal section through my improved lubricator.

Figure 2 is a vertical transverse section taken substantially on line 2 2 of Figure 1.

Figure 3 is a fragmentary detail taken on line 3 3 of Figure 1.

Figure 4 isa fragment-ary detail taken on line 4 4 of Figure 2.

The journal to be lubricated is indicated at A and it is to be understood that the same will carry an annular surface, such asthe 10, 1925. Serial N0. 55,603.

wheelhub B, adapted to engage a' contact rod 1 for operating the lubricant pump mechanism. rThe journal will support a box through the usual bearing C, the sides of the box being indicated in dot and dash lines at D in Figure 2.

v The body ofthe lubricator includes a cellar 2 the inner end of which is united with a depending lubricant reservoir 3 having a lling spout 4 and a removable cover 5 provided with an integral vertical portion 6 which also :forms an inner end wall i'or the cellar 2. The top of the iilling spout is substantially at the same level as the bottom of the cellar. Hence, when the reservoir is filled, the lubricant will not rise above the cellar floor.

A waste containing sub-cellar 7 is yieldingly supported from the floor of the cellar by a spring 8, the expansion movement of which' is limited by a plate 9 pivoted at 10 on the cellar iioor and tree to be compressed by the sub-cellar to any necessary extent, but having its upward movement limited by the engagement of its pivoted end with the floor oiE the cellar.

rEhe bottom of the sub-cellar includes a Cylindrical chamber 11 adapted to house the pump cylinder 12, the latter having fixed thereto adepending intake 13, which extends into the lubricant reservoir 3 and is provided with a screen 14 and with a check valve 15. A hollow pumppiston or plunger 16 is slidably mounted in cylinder 12 and includes a flap valve 17 pivoted at its upper edge and also carries a projecting stem 18 extending lengthwise of the sub-cellar into a position where it may engage the inner end of contact rod 1. When the plunger is 'forced inwardly by contact rod 1 it is subsequently returned to its original position by a spring 29 which is seated on a shoulder formed on the end of the plunger. To permit oil to pass hrough the end of the plunger, the same is perforated beyond the spring seat as indicated at 30. rlransverse passages 31 in the plunger lead from perforations 30 to the axial opening in the plunger leading from Hap valve 17.

1n order to prevent rotation of plunger 16 in its cylinder 12, 1 provide the plunger with an upwardly extendingv dowel 19 adapted to slide in a longitudinal slot provided in the upper portion of cylinder 12. This prevents the rotation of the plunger such as will intertere with the easy operation of the flap valve 17. e

rlhe outer end of cylinder 12 is adapted to contact with the innerl face of wall 6 provided on removable cover 5 and upon removal of cover 5 from the lubricator, cylinder l2 with plunger 16 may be easily withdrawn from the remainder of the lubricatoi' and repaired or replaced, if necessary.

To prevent the discharge of lubricant by the journal over the sides of the cellar, l provide sheet metal shields 2O extendin upwardly from the inside of the cellar side walls 2l into engagement with the lower edges of thejournal bearing C. Shields 2O are preferably yieldingly supported by springs 22 mounted on a sheet metal base 23, thereby providing an adjustable shield forY the purpose described.

lntlie earlier manufacture of my lubricator, it has been customary to provide the cellar with an integral lug for receiving the cellar pin. This made necessary the special drilling and, in many cases, the special location of the lug in order to accommodate driving boxes having their cellar pin holes located at diflerent heights. ln order to eliminate this undesirable feature, l have provided the depending wall 24 of the reservoir with integral ears 25 located a substantial distance below the bottom of the cellar and below any likely location of the cellar pins. F or each installation, l provide small bars 26 which may be bolted to ears 25 and extend upwardly therefrom as far as necessary to take lthe cellar pins E and to support the bottom of the cellars. This construction permits me to make the depressed middle portion 2'? of the cellar wider than could be done otherwise, and it isA comparatively easy to provide various diniensioned bars for applying the cellar to different types of driving boxes.

The cellar may be provided with downwardly facing shoulders 28 adapted to rest on corresponding driving box shoulders or, where the driving boxes are provided with a straight inner face, the cellar of said wall may extend downwardly without shoulder 28.
