To all lwhom/15 may concern:

Be it lmown that I, VILLIAM S. MCCLUNG, a citizen ofthe United States, residing at Hagerman, in the county of Chaves, State of New Mexico, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricators for use in connection with vehicles, machinery, etc., with wheels to be oiled or greased to prevent friction n the axle or spindle of the Wheels.

An object of the present invention is to provide a receptacle for oil. or grease, the receptacle being provided with means for regulating the feeding of the lubricant, said means including a novel manually controlled valve and presser disk, the exposed actuating portions of said means being housed Within a cap carried by the receptacle so as to prevent the access of dust to the lubricant.

Wit-h the above Iobjects in View the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications Inay be made in the minor details of construction Within the scope of the appended claims.

In the accompanying drawings forming part of this specilicationzH-Figure v1 is a longitudinal sectional View through the device with the valve in position for closing the outlet. Fig. 2 is a cross sectional View taken on the line 2--2 Fig. 1. Fig. 3 is a cross sectional View taken on the line 3-3 The lubricator@ consists of a cylindrical receptacle 13 provided centrally in the bottom With an exteriorly threaded outlet nipple 14 designed to screw into thebearing to which the lubricant is applied. An intoriorl'y threaded cap 15 closes the top of the receptacle and is provided cxteriorly with Wrench faces 16 to which an' ordinary Wrench may be applied for unscrewing the cap in order to replenish the lubricant. An eX- teriorly threaded cylindrical plug 17 is screwed into the receptacle at the open end thereof and is prcJided on the outer face with spaced lugs 18 which forms means for applying or removing the plug. The plug is provided with a smooth centrally disposed openin 19.

A tu e 2O is journaled in the opening 19 and is provided with a stop pin 2li which bears against the inner face of the plug, and is further provided with radial rejections 22 which bear against the outer ace of the plug, the pin and projections preventing movement of the tube longitudinally through the opening, the projections further forming' means for rote-.ting the tube. Screw threads 23 are formed on the outer face of the tube, and mounted upon the tube is a presser disk 24 having a centrally disposed threaded opening 25 receiving the threads of the tube.

.The disk conforms to the here of the receptacle and is provided with oppositely disposed radial notches 26 in which lit guide lugs 27 projecting from the inner Wall of the receptacle. By rotating the tube presser disk is moved in the direction of nipple and forces the lubrican sure through the outlet nipple p A valve stern 28 is disposed within the tube 20, and is provided for a pc 'ion of its lengt-h With screvr threads 29 to ge nietl ing screw threads formed in the here of thev tube. The stein is provided at the inner end with a plug valve 3G adapted close the bore of the outlet nipple 14, is .itinen more provided at the outer end with Wings 31 which form ineens for r toting the stem. whereby to advance or retract the same in the tube and close the valve to any desired extent in order to regulate the feeding of the lubricant through the outlet ni It will be observed that the in ins for rotating both the tube and the va are exposed on the outer face of t.' 4 and are completely housed with the cap 15 which threadll on to the lubricant receptacle, the said means being thus g ""iected from Contact with dust or ot` matter, and access of the latter int bricant positively prevented.

Formed in the side of the r is an oil opening closed l 33. Upon advancing the pr-L upper limit of movement en may be inserted in the oil op receptacle filled up to the o presser disk then being moved to feed the oil under pressure tlirou casing outlet 14. Y

What is claimed, is ty 1. A lubricator including a' receptacle, an

ide-r pres outlet disposed in the bottom thereof, a removable plug forming a closure for the top of said receptacle, a removable cap on said receptacle forming a housing for said plug, a tube revolubly mounted in said plu means for rotating said tube, a presser dis threaded upon said tube, interfitting guide means between said disk and said receptacle, a valve stem in said'tube having a Valve to zlose said outlet, means for rotating said stem, and a screw thread connection between said stem and the inner wall of said tube.

2. A lubricator including a tubular re- Aceptacle, an outlet nipple disposed in the bottom thereof, a removable plug forming a closure for the top oli said receptacle, a cap on said receptacle housin said plug, an exteriorly threaded tube havlng-a smooth end portion revolubly mounted in a smooth bore opening formed in said plug, means on said end portion for manually'rotating the tube, a presser disk having a threaded opening receiving the threaded portion of said tube, interfitting guide means between the edge of said disk and the inner Wall of said receptacle, avvalve stem in the bore of said tube having a valve at the lower end adapted to close the bore of said outlet nipple, and having at the upper end means for rotating the stem, and a\screw thread connection between said stem and the inner wall of said tube.

In testimony whereof, I affix my signature, in presence of two witnesses.
