Specification of Letters Patent.

Application filed May 8, 1915. Serial No. 26,717.
To all whom it may concern:
Be it known that I, EDWARD H. SWEELEY, of Richmond Hill, in the county of Queens and State of New York, have invented a certain new and useful Improvement in Lubricators, of which improvement the following is a specification.
My invention relates to lubricators of the class or type adapted to effect the supply of pulverized lubricating material, such as graphite, to .the interior ofengine or pump cylinders, or other surfaces requiring lubrication, and its object is to provide an appliance of such type which shall be of simplified and inexpensive construction, and in the operation'of which a constant regulated feed of lubricating material will be effected, without tendency to clogging in its traverse through the lubricator.
The improvement claimed fully set forth.
In the accompanying drawings: Figure 1 is a vertical central section through a lubricator embodying my invention; Fig. 2, a transverse section through the same, on the line a a of Fig. 1; Fig. 3, a side view of the plunger; and, Fig. 4:, an end View thereof.
In the practice of my invention, I provide, for the reception of the lubricating material, a lubricating cup, 1, having an open top, which is closed by a screw cap, 2, and lateral lugs, 1, formed on its cylindrical body, for attachment to a suitable support. A tubular extension, 1 projects outwardly from the closed bottom of the lubricating cup, and a socket, 1, concentric therewith, is formed on the inside of the bottom of the cup. The outer extension, 1 is threaded at its lower end, to which a lubricant delivery pipe, 3, is connected by a union coupling nut, 3. Communication between the interior of the lubricating cup and the idelivery pipe is controlled by a plug cock, 4, actuated by a hand wheel, 4:.
The socket, 1, of the cup, is internally threaded, and a correspondingly externally threaded and centrally bored bushing, 5, which ispreferably made of Monel metal, to reduce wear, is fitted therein and engaged therewith. A plunger, 6, having a head or piston, 6 of larger diameter than its body, is fitted loosely in the bore of the bushing, the diameter of its body being about .005 of is hereinafter an inch less than that of the bore, and a conical face, 6 which forms a valve, and which is adapted to seat on a correspondlngly bored face at thetop of the bore of the bushing, is interposed between the head I Fig. 4, thereby reducing its area in transverse section, and providing channels for the passage of lubricating material around it, through the reduced bore of the tension, 1
The lift of the plunger, 6, is controlled and regulated, as desired, by an adjusting stem, 7 which is threaded to engage the cap, 2, and is held in adjusted position by a lock nut, 7, and in order to insure the positive seating of the conical face, 6 of the plunger, upon the bushing, after the parts have become slightly worn, a helical spring, 8, surrounding the upper portion of the plunger and the lower portion of the adjusting stem, is preferably interposed between the piston, 6 and the lock nut, 7*.
In the operation of a lubricator of substantially the construction above described, the lubricating cup having been supplied with lubricating material, the delivery pipe connected to the cylinder, the surface of which is to be lubricated, and the cock controlling said pipe opened, the plunger will be raised when pressure is exerted in the receiving cylinder, and lubricating material supplied to the delivery pipe, through the narrow annular space around the body of the plunger and the contracted bore in which the lower extension of the plunger is fitted. The lift of the plunger, and consequent degree of rapidity of feed, are regulated as required by the adjusting stem. Upon the reduction of pressure by the exhaust from the receiving cylinder, the piston of the plunger will be seated, cutting off further supply, and the exhaustion of pressure will carry the lubricant into the receiving cylinder. The alternate movements of the plunger will continue during the movements of the piston in said cylinder. The action of the spring insures the seating of outer exthe piston, in the event of irregularities in the contacting surfaces being occasioned by Wear.
I claim as my invention and desire to secure by Letters Patent:
1. In a lubricator for feeding pulverized lubricant, the combination of a lubricating cup, a delivery pipe adapted for communication with a member to be lubricated, a plunger fitting loosely in a passage leading out of the lubricating cup and having an extension working in a bore which is of smaller diameter than said passage, and leads therefrom to the delivery pipe, and a piston fixed on the plunger and seating at the inlet of said passage.
2. In a lubricator for feeding pulverized lubricant, the combination of a lubricating cup having an outwardly leading passage, a bushing removably connected to said lubricating cup and having its bore communicating with said passage, a delivery pipe adapted for communication with a member to be lubricated, a plunger fitting loosely in the bore of the bushing and having an extension Working in a bore of smaller diameter leading to the delivery pipe, and a piston fixed to the plunger and seating on the inlet end of the bushing.
3. In a lubricator for feeding pulverized lubricant, the combination of a lubricating cup, a delivery pipe adapted for communication with a member to be lubricated, a plunger fitting loosely in a passage leading out of the lubricating cup and having a longitudinally channeled or reduced extension Working in a bore which is of smaller diameter than said passage, and leads therefrom to the delivery pipe, and a piston fixed on the plunger and seated at the inlet of said passage. I
4;. In a lubricator for feeding pulverized lubricant, the combination of a lubricating cup, a delivery pipe adapted for communication with a member to be lubricated, a plunger fitting loosely in a passage leading out of the lubricating cup and having an extension working in a bore which is of smaller diameter than said passage, and leads therefrom to the delivery pipe, a piston fixed on the plunger and seating at the inlet of said passage, and a closing spring bearing on said piston and on an abutment fixed to the.
lubricating cup.
