Description

UNITED STATES PATENT OFFICE.
VILLIAM I). MILLER, OF BROOKLYN, NE\V YORK, ASSIGN OR TO THE VILLIAM P. MILLER COMPANY, OF SAME PLACE.
LUBRICATOR.
SPECIFICATION forming part of Letters Patent No. 448,785, dated March 24, 1891. Application tiled December 6, 1890. Serial No. 373,772. (No model.)
To @ZZ whom it may concern.-
Be it known that I, WILLIAM P. MILLER, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Lnbricators, of which the following is a specification. I
My invention relates to an improvement in lubricators in which provision is made for forcing a lubricant in a viscid or semi-liquid state into contact with the part to be lubricated.
A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l represents aview of the lubricator in vertical section. Fig. 2 is a transverse section through the line o; ot' Fig. 1, looking downwardly toward the piston; and Fig. 3 is a top plan view.
My present invention con templates a piston provided with a hollow stem, through which the lubricant is forced onto the part to be lubricated, the said piston being fixed, and the cup or shell containing the supply of lubricant and within which the piston operates being made movable relatively to the piston.
A represents the piston, here shown as cylindrical and provided with a hollow or tubular stem a. The stem a is conveniently provided with a squared portion a for the engagement therewith of a wrench for the purpose of screwing the stem into the bearing or other suitable support, in position to discharge the lubricant onto the journal or part to be lubricated. For the purpose of its attachment the said stem is provided with an externally-threaded portion a2 at its end. The said stem is also provided with an interior screw-thread B, extending from the face of the piston toward the end of the stem, for the purpose of adjusting therein the verticallymovable tubular stem C of the cup or shell D. The cup or shell D is preferably formed ot` brass or other suitable metal capable of being spun or pressed into shape, and is adapted to receive within it, with an easy-sliding fit, the piston A.
The tubular stem C projects from the central portion of the top d of the cup D within 5o the cup toward its open end, and is provided with an exterior screw-thread c, adapted to register with the interior screw-thread B in the piston-stem. rllhe tubular stein is conveniently provided, as herein shown, with a head E, provided with shoulders c at the point where the threaded portion of the stern begins, which shoulders are intended to overlap the adjacent edges of the top d of the cup o1' shell, and thereby form a convenient joint for soldering the stem firmly to the shell.
Near the upper end of the stem O, within the cup or shell D, the saidstem is provided with openings c therethrough, which establish communication between the interior of the shell D and the interior of the stem C.
In operation the cup D, having` been removed frorn the piston A, may be charged with the lubricant, and then by replacing it over the piston A and engaging the threaded stem O with the interior threaded stern B the 7o piston A may be forced toward the top d of the shell, to as little orgreat an extent as may be desired, by simply rotating the cup or shell, and the lubricant will be thereby forced through the openings c in the stein C and along down the stems C and B into contact with the part orparts to be lubricated thereby.
To furnish a convenient hold for the lingers in rotating the shell D to force the lubricant I have knurled or milled the outer edge of 8o the top d, as shown at CZ', Fig. 3.
The lubricator as thus constructed is well adapted to general use, both in connection with fixed and movable parts.
What I claim is- A lubricator comprising a piston having a tubular stem screw-threaded interiorly,.and a cup or shell adapted to receive the piston therein With a close sliding tit and `provided with a tubular stem screw-threaded to register oo with the interior thread in the piston-stem, the stem connected with the cupor shell being provided with openings through its Walls, through which communication is established between its interior and the interior of the 95 cup or shell, substantially as set forth.
