RAILWAY JOURNAL LUBRICATOR Filed Aug. 22, 1931 2 Sheets-Sheet 1 hue/Von Q/forney Patented June 5, 1934 UNITED STATES PATENT OFFICE Application August. 22,

12 Claims.

The invention relates to lubricating devices applied to railway journals and is of the general type illustrated in Patent 1,794,457, issued to me March 3, .1931, in which the lateral movement of the axle; journal and wheel relative to the driving box, and cellar therein, is utilized to operate a pump for pumping oil from a reservoir in the cellar to the journal or a distributor applied thereto.

One object of the invention is to provide a lighter device thanhas been used heretofore thereby facilitating its application to the journal and journal box and its removal therefrom.

Another object is to increase the capacity for storing lubricant.

Another object is to avoid the escape of lubricant from the lubricator along the surface of the.

journal.

Another object is to improve the lubricating function of a device of the type described when the same has a substantial quantity of water applied to it.

Another object is to provide a pump assuring adequate supply of oil to the journal under unfavorable pumping conditions and providing for return to the reservoir of surplus oil pumped under favorable conditions. 7

Another object is to increase the capillary feed of oil to the journal.

Another object is to provide a pump carried by the cellar body and removable therefrom for inspection and cleaning.

These and other detail objects of the invention are attained by the structures shown in the accompanying drawings, in which Figure 1 is a top View of the body of the lubricator and a portion of the distributor provided therein.

The engine truck journal lubricator shown in 1931, Serial No. 558,719 (Cl. 308-84) Figures 1 to 4 comprises a cellar including a body portion having a bottom wall 1, side walls 2 and end walls 3 and 4. The cellar includes a box-like reservoir chamber 5 projecting beyond one end of the body portion and below the bottom wall 1 thereof. The side walls 6 and the outer wall 7 of chamber 5 extend upwardly above the level of the body bottom wall 1 and the body end wall 4 forms the inner end wall of the chamber 5.

A hollow member 8, disposed longitudinally of the body portion and applied to one of the side walls 2 near the bottom thereof, receives the contact rod 9, engaging the Wheel hub 10, and forms a housing for the pump cylinder 15 having a piston 11 which is reciprocated by rod 9.

The pump cylinder is inserted through a suitable opening in wall 4 and has an intake arm 12 which extends downwardly towards the bottom of chamber 5 and is held in position by an adjustable stud 13 mounted in the outer wall 7 of chamber 5.

The sub-cellar 14 has a central column 140, projecting from' its bottom wall which receives a spring 16 and a sleeve 39 whereby the sub-cellar is yieldingly supported on the block 390: of the cellar. The engaging faces of sleeve 39 and block 39a are concave-convex so that the sub-cellar may tilt to the position in which its upstanding end walls will contact with the journal J.

The upper edges of the side walls of the subcellar are recessed intermediate their ends to provide free passage of oil with the upwardly moving side of the journal to the bearing 20 which is undercut or rounded to facilitate the intrusion of the oil between itself and the journal.

The bottom of sub-cellar 14 extends downwardly alongside of member 8 into the lowermost portion of the body of the cellar. Springs 33 in subcellar 14 yieldingly support a pan 17 in which are seated a plurality of pads 18 of felt or other suitable material having capillary properties A conduit 19 leads from housing 8 into block 39, the passage being continued through the block, hollow sleeve 39a, and discharge passage 37 in the upper end of column 14a to the face of the journal and being provided with a ball check C. A by-pass D leads from the interior of column 14a. through the wall thereof whereby oil in excess of that passing by the ball check will return to the reservoir.

The bearing 20 of brass or similar material rides on journal J and extends down the sides of the same with its lower edges overlapping the inside faces of cellar walls 2, as indicated at 21, so as to prevent the escape of oil over the sides of the H lar to chamber 5.

cellar. Sub-cellar 14 and bearing 20 are provided with diverging wings 22 and 23, respectively, which serve to wipe oil on the journal beyond the end of the sub-cellar or the bearing and return it to the ends of these members until it runs down into the reservoir. Grooves G render the effective length of the bearing substantially less than that of the sub-cellar and this increases the efficiency of wings 22 and 23.

Horizontal flanges 24 extend inwardly from each end wall of the cellar at about the level of the top of chamber 5 and serve as anti-splash plates to reduce loss of lubricant which might otherwise splash over the edges of walls 3 and 4.

The lubricator is provided with an inner end member serving as an oil baflie and including an upright plate 25 having an opening for surrounding journal J and, preferably, lined with a layer 26 of felt or similar packing material to engage the cellar end wall 4 and the ends of side walls 2. The end member also includes a cover 27, similarly lined, for an opening 32 in the top wall 37 of chamber 5 and one or more diagonal braces 28 extend between plate 25 and cover 27 at points spaced from the corner formed between them. The end member is held in place by a pin 29 extending through lugs 30 provided on end wall 4 and projecting through end plate 25. The pin engages the corner portion of the end member and its removal permits the end member to be slid along the axle away from the cellar. Upon removal of stud 13, the intake arm 12 and associated parts may be rotated and the pump cylinder withdrawn from the lubricator for cleaning, etc. The reservoir is normally filled through a spout 31 at one side of cover 27.

A substantial opening 34 in the, upper portion of wall 4 immediately beneath flange 24 provides an overflow passage for oil leading from the cel- A restricted opening 35 just above the bottom wall 1 of the cellar provides a drain for any water in the lubricator whereby the water may escape from the body portion to chamber 5 and may be drained from the latter through a plug inserted at 36. Chamber 5 may be provided with an automatic water drain as described in my Patent 1,748,982, issued March 4,

In some previous structures, the introduction of water into the lubricator from a hose, rain or otherwise would interfere with its operation as the water would be pumped up into the distributor only to flow back immediately to the reservoir and again enter the pump, the oil floating on top of the water at all times and being thereby excluded from the pump. The present construction avoids this result as the partition between chamber 5 and the lower portion of body 1 temporarily traps excess water although the overflow opening 34 permits the oil to circulate freely and the opening 35 prevents undue accumulation. of water in the body.

The cellar may be supported in any approved manner and one form of support is indicated by the angles 38 welded to the sides of the cellar and mounted upon suitable carrying elements in the journal box (not shown).

Preferably, the cellar body and reservoir are formed of relatively light sheet metal parts out and welded together and the housing for the pump cylinder and contact rod is formed separately and welded to the side wall of the cellar. This facilitates the application and removal of the lubricator as the device is much lighter than those previously used which included cast body portions.

The body and reservoir chamber, pump and distributor constitute a self-contained unit which will continue to function irrespective of the presence or secure fit of the detachable end member 2527. All of the features described contribute to avoiding the loss of oil due to the pumping of a larger quantity than is required for lubrication at any one time. Some of these features may be included in the heavier construction previously used but the sheet metal body is especially adapted to embody these features without any disadvantage because of lighter construction.

In the modification illustrated in Figures 5, 6 and 7, the invention is shown applied to a driving wheel journal and includes most of the features in the structure previously described. A somewhat different type of pump is shown in which the contact rod 40 and a continuation 41 thereof extend through the cellar and the pump piston 42 is located in the lower portion of the reservoir 43 as described and claimed in my copending application Serial Number 403,027, filed October 28, 1929. The sub-cellar 44 is supported by springs 45 and is positioned between flanges 46 on the end walls of the body of the collar, these flanges being inclined downwardly as shown to underlie the wiping wings 4'? on the ends of the sub-cellar.

The cellar side walls 48 are preferably received in recesses formed in the driving box walls 49 so that any oil discharged from beneath the bear ing 50 will fioW down the driving box walls into the interior of the cellar instead of escaping over the side walls of the cellar and being lost.

The cellar is supported in the usual manner by a bridge 51 having depending ears 52 receiving suitable bolts carried by the usual lugs 53 on the driving box. Ears 54 depending from the bottom wall of the cellar also receive these bolts to hold the cellar in position.

The bearing 50 is provided with wiping wings 55 corresponding to the wings 23, shown in Figure 2, but formed separately from the bearing and having portions inserted in the bearing.

Obviously, other variations in structure could be accomplished without departing from the spirit of the invention and the exclusive use of all such modifications as come within the scope of the appended claims is contemplated.
