AUTOMATIC L BRIcA ToR;

To all whom it may concern Be it known that I, CLYDE CECIL SILLs, a citizen of the United States, residing at Dardanelle, in the county of Yell and State of Arkansas, have invented certain new: and useful Improvements in Automatic 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 comprehends certain new and useful improvements in lubricators, and has for its primary object to provide a device of this character especially adapted for lubricating cylinders and the like.

. Another object of the invention is to provide an automatic lubricator of thischaracter which will be of such construction and operation that the feeding of the oil to the cylinder will be controlled by the pressure from the cylinder and a spring around the valve stem and connected with a stationary portion of the lubricator. The invention has fora further object to provide a device of this character which will be automatic in its operation, of extremely simple construction and highly eflicient in use,as well as strong and durable.

WVith'these and other objects in viewas tion proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For acomplete understanding of my invention, reference is to be hadto the following description and accompanying drawings, in which 7 r. v y

Figure 1 is a longitudinal section through the complete device and a portion of a cylinder towhich the automatic lubricator is" numerals, 1 designates the oil cup or reservoir having a sectional feed pipe 2 depending therefrom and secured in a coupling 3 within which a vertical partition 4: is formed and connected by its opposite or upper and Specification of Letters Patent.

lower edges to opposite sides of thecou pling 3 by the horizontal partitions 5, it

being understood that the opposite side edges of the vertical partition 4 are connected wlth the coupling 3, and the vertical partition 4 is provided With a conical valve seat G'W ithi'n WhlCh ilS adapted tobeseated the conical pressurepcontrolling valve 7 V mounted upon the valve stem 8 threaded through one wall ofthe coupling '3 and having the hand "wheel 9 or the like'mounted upon'its outerface, by means of which said stem 8 maybe readily rotated to move the valve 7 to proper position 'with'respect to the valve seat 6.' i

It will beunderstood that the coupling 3 has connected therewith a pipe connection 10 which is secured in the wall of the compression cylinder of an air pump or'thelike and having the piston 12 adapted to reciprocate therein. l

-' The feed pipe-2 .oil chamber 13. 2

formed intermediate-its ends by the lower and upper "horizontal partitions 14: and 15 provided; respectively with the, valve open The valver7 is adapted for engagement with the valve seat. 6 and the compression from the cylinder11 forces the valve '18 against the lower, face of the lower p'arti tion 1% andthereby closes the valve opening 16, it being understood that the valve 18 is mounted upon the slidable rod 19. 4 This 7 Will prevent oil from passing out of the oil chamber 13. Assoon as the piston12 starts its return stroke, however, the pressure is 1 reduced and the valve 18 isxmovedflaway from the valve opening 16, by means of the expansion spring 20 to permit the lub ricating oil within theoil chamber 13 to pass into the coupling f3-and through the valve opening 6-to the cylinder 11 and the piston 12 withinthe same. The expansion spring 20 is secured around the stem 21 of the valve 22, upon the stem 19 and adapted to be ad- 21 of the valve 22 depending through the valve opening 17 in the xupper'partition 15 and being prevented from rotating by means 'justed longitudinally ;of the; same, the, stem of the expansion spring 20 which has one end secured to the lower end'of the stem 21, while its opposite endis secured to the under face of the upper partition 15, as will be readily understood by referring to'the drawing.

The valve 22 stem 21 are adjusted 1011 gitudinally upon the stem 19 in such manner that when the valve 7 is in open position, the valve 22 also is in open position and vice versa, the spring 20 serving to close the valve 22 by pressing the same with the rod 19 downwardly upon a decrease of steam pressure from the cylinder 11. The valve 22 is locked against accidental movement on the rod 19 by the enlargement or jam nut 23 formed on the lower extremity of the tube 21, which is extended through the oil cup or reservoir cover 25 at its upper end and has the annular flange 26 formed around the same for the purpose of rotating the tube 24: to adjust the position of said tube 2% with respect to the rod 19 and position said jam nut 23 against said valve 22, it being un derstood that the j am nut has threaded en gagement with said rod 19. It will also be understood that the stem 19 has a hand wheel 27 or the like formed on its upper free extremity above the flange 26 of the tube 24, whereby said stem 19 may be readily rotated in either direction to adjust the position of the valve 22 and valve stem 21 upon said stem 19. It will further be understood that the cover 25 has a depending annular flange 28 threaded upon the upper end of the oil cup or reservoir 1, and it will be evidentthat as the feed pipe 2 is formed in sections and the sections are connected near the center of the oil chamber 13, as shown at 29, the valve 22 andvalve stem 21, as well as the expansion spring 20 may be readily secured in position or removed. Further, should any of such parts become worn or broken, they may be readily re placed at small cost.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the details of construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed, or sacrificing any of the advantages thereof.

What is claimed is 1. A device of the class described comprising an oil reservoir, a feed pipe leading from said reservoir to a member to be lubricated, a pair of transverse partitions positioned in said feed pipe, a stem reciprocally mounted through said oil reservoir and feed pipe, a tube around said stem, a valve on the lower end of said stem and adapted to be engaged Copies of this patent may be obtained for with the lower partition, a second valve adjustably mounted on said stem and adapted for engagement with the upper partition upon disengagement of the lower valve from the lower partition, and a jam nut carried by said tube and engaged with said stem.

2. A device of the class described comprising the combination with a compression cylinder and an oil reservoir; of a feed pipe, said feed pipe having an oil chamber formed therein by a pair of spaced transverse partitions, said feed pipe being formed in sections connected intermediate the ends of the oil chamber, a stem slidably and rotatably mounted in said feed pipe and oil reservoir, a tube around said stem, a jam nut carried by the lower end of said tube, said transverse partitions having valve openings formed therein, a pair of valves mounted upon said stem, the lower valve being adapted to be forced against the lower transverse partition to close the valve opening thereof, and means secured to the upper transverse partition and the valve for seating said upper valve and forcing the lower valve away from the lower partition.

3. A device of the class described comprising an oil reservoir, a compression cylinder, a feed pipe ieadingfrom said oil reservoir, a cover for said oil reservoir, a coupling, means for connecting the coupling to the compression cylinder, said oil feed pipe being connected with said coupling, a pair of spaced partitions in said feed pipe, a tube extended through the cover for said oil reservoir and depending into the feed pipe, a stem rotatably mounted in said tube, a pair of valves mounted upon said stem beneath the lower end of the tube and adapted for engagement with the partitions to control the passaage of oil through said partitions, the lower valve being adapted to be seated by the pressure from the compression cylinder, a valve mounted in the coupling to cut off communication between the cylinder and the feed pipe, and a jam nut carried by the tube and engaged with the upper valve carried by said stem.

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