OIL our.

Application filed March 25, 1925. Serial No. 18,209.

This invention aims to provide novel means tor lubricating machinery of any kind, regardless of whether the oil cup is fixed or movable.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the invention appertains.

Although preferred forms have been shown in the drawings, it will be understood that a mechanic, working within the scope of what is claimed, may make such changes as his skill may suggest, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 showsin longitudinal section, a device constructed in accordance with the invention, parts being in elevation; Figure 2 is a transverse section on the line 22 of Figure 1; Figure 3 is an elevation showing a slight modification in the valve; Figure 4 is a tragmental longitudinal section showing a modification in the device delineated in Figure 1; and Figures 5 and 6 are sectional views illustrating modifications in that form of the invention. which is illustrated in Figure 4.

Referring particularly to Figures 1 and 2,

there is shown a cup 1, adapted to contain a lubricant, and including a receptacle 2 having a neck 3 which is externally threaded as at 4 for engagement with the part to be lubricated, there being a wrench shoulder 5 at the place of juncture between the neck 3 and the cup 1, so that the cup may be turned readily to thread it into place. In the lower end of the neck 3 there is a recess 6 communicating with a reduced bore 7 which, at its upper end, communicates, with a flared seat 8 formed in the bottom of the receptacle 2. A closure 9 for the receptacle 2 is provided, and may be in the form of a cap having a marginal flange 10 threaded at 11 on the receptacle 2, the closure 9 having a. wrench lug 12 whereby it may be rotated readily. The closur 9 carries a fixed inwardly extended stem 1 1, which is inaccessible when the closure 9 is mounted on the receptacle 2.

The numeral 15 designates a valve including a body 16 having a reduced stem 17, the body 16 having a tapered end 18' adapted to fit in the seat 8. The stem 17 of the valve 15 is mounted to reciprocate in the bore 7 and is supplied with longitudinal grooves 19.

The device shown in Figure 1 of the drawmgs and above described is adaptedto be mountedon some piece of machinery which moves. The valve 15 is located below the stem 14 of the closure 9 and. is spaced slightly therefrom. As the piece of machinery which carries the cup 1 moves, the valve 15' will move upwardly and downwardly, the part 18 I of the valve moving to and from the seat 8, thereby permitting the lubricant to pass from the receptacle 2 through the grooves 19 to the part tobe lubricated.

When it is desired that the part to be lubricated shall have an increased supply of oil, then the valve 15 is replaced by the valve 20 of Figure 3, the valve 20. comprismg a body 21 having a tapered end 22, the stem being designated by the numeral 23 and the numeral 24 marking the grooves in the stem. It is to be observed that the body 21 of the valve 20 is shorter than the body 16 of the valve 15. Consequently, the valve 20 will have an increased amount of play to and from the end of the part 14. There maybe as many valves as desired, the valves having heads of difierent lengths. By substituting one valve for another, the amount of lubricant delivered may be regulated.

In devices of the class described, as hitherto constructed, it has been the common practice to limit the movement of such a part as the valve 15, adjustably, through the instrumentality of a screw threaded for adjustment into such an element as the cap 9. The disadvantage incident to the use of an adjustingscrew is that, after one person who understands thoroughly the amount of lubriby rendering the stem 14 longitudinally adjustable, but, rather, by substituting one valve for another,'the valves having heads of differentlengths, as illustrated in the

parts

16 and 21. A person expert in lubrication, and well advised as to the amount of.

lubricant required by any particular bearing,

sets up the device as shown in Figure 1, and

there it remains, there being no adjusting screw to be tampered with.

It has been stated hereinbefore that the article shown in Figure 1 is adapted to be movement. vIn the event that it-is desired to use the device on a machine part which has no movement, that is, upon a dead bearing when recourse may'be'h'ad to the structure shown in Figure l. In that figure,

parts hereinbetore described have been 'des ignated by numerals previouslyused, with the sutiix a.

. The'valve ismarked by the numeral 25 and includes a body 26 and a stem-27, the groovein the stem being shown at 28. The grooveis extended laterally across the. lower end of the body 26 of the valve 25, to permit the passage of lubricant, because the oil cup itself has nomovcment. Such a valve asthe valve 25 may be replaced by the valve 30 ot' Figuref), the body of the valve 30 being designated by the numeral 21, the stem being shown at 82, the groove at 33, and the extension at 3%. The grooves 33 3a are deeper than the corresponding elements 28%29, and by substitutingsuch' a part as the valve 30 for the valve 25, an increased flow of oil may be aflorded.

In Figure 6, the valve 30 is shown at 36 and includes a body 37 and a stem 38, the stem having grooves 39 on both sides, these grooves being extended, as shown at a0, along the lower surface of the body 37.

Having thus described the invention, what is claimed is 1. In a lubricator of the class described, a, receptacle, a closure for the receptacle. a stem of determined length fixedly and rigidly secured to the closure and housed completely within the receptacle, the receptacle having an outlet for lubricant, and a valve ,slidably mounted in the receptacle in substantial alinement with the stem, the valve controlling the outlet. 1

2. A lubricato'r'of the class described, constructed-as set forth in claim 1 and further characterized by the provision of means whereby the valve may be spaced at variable distances from the inner end of the stem.

In. testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
