nois, have invented a new and useful Improvement in Oilin Devices, of which the following is a 'speci cation,"the p'rinci le of the invention being herein explaine and the best mode in which .Ihave contemplated applying that principle, so as to distinguish My invention relates to oilin devices and principally to that 'classof devices in which oil is distributed .by pressure to various points to which .it is required to be'conveyed. I

The object of such an invention is" to produce a device of said. character,whereby such distribution may be'economically and eflicien'tly efiected.. I

Said invention consists of the means hereforth in the claims.-

The annexed-drawin scription set forthin, etail-certain means for carrying'out my. invention,'-said disclosed means constituting butone of vari-' ous forms in which the represents a vertical cross sectional view 'of the device, embodying my said invention, portions-0f such device being shown in side elevation. Fig. -aII represents ,a top plan view of aipiston constituting part-0f said device.

The oil cup Ais provided vwith a cylindrical bore in, whic with a cries of parallel grooves a, as shown in Fig. I. The central port-ion of the piston is formed'vvith 'anoutwardly'projecting por-ftion which isYc onica-l in -'form, and zifo rms a valve b. Coaxial wit-h such valve is a bore 6 which pierces the piston, and forms a passage-way-through the same by means of which oil may pass from .one' side of the.

piston to the other. Surrounding such bore is formed an upward projection 6 upon I Specification of Letters Patent. Application filed Junie, 1903. Serial No.

means of which the extremity of a pipe or duct F may be secured to the cup through the medium of coupling G. The end of the pipe i is threaded to receive a check valve holder H in the end of which is formeo ii. valve chamber 71, in which is seated the check valve 71.. This valve is located in manner such that it may close the end opening if of the valve chamber, which is in aiinement with the end opening a in the hippie u, -.he result of liquid under pressure within the pipe F, when the pipe is detached as will further appear. The valve guide it is of a length such that when the pipe and valve holder are detached from the nipple at, it projects from the end of said holder, when the valve it is in its closing position. The opening or in the nipple is made of a diameter smaller than that of the opening; it", so that it will be seen that when the nipple and valve holder are in juxtaposition, the check valve will be held to permit the opening it to be normally open, and the passage of the oil permitted from the pipe into the nipple bores a and a and so into the aforementioned chamber in said cup which serves as passage-way to the outlet (L2.

The lower portion of the oil cup is formed with the throaded'portion a which may be attached to the mechanism to be oiled, and intermediately of such portion and the lower cup portion formed a feed sight portion a into which projects a nozzle a pierced by the bore (1/ which forms as before stated the outlet to cup A. Coaxial with the bore a and through the threaded portion a is formed a bore a having an enlarged upper portion as shown in dotted lines in Fig. I.

The upper portion of the piston B is formed with two ears 5 which may be utilized to remove the piston from the cup when such removal is required. v

The boss 1 formed upon the upper portion of the cap t] is formed with a transversely located slot 0 which intersects the axis of the thread hore formed in the cap, as shown in F ig. I. This slot effects a formation of a movable piece (i having one free end and the other fixed, as will be readily understood. A screw seat is formed in said piece 0 as shown in the dotted lines in Fig. I, in which is seated the screw 0 which has threaded engagement with the lower portion of said piece as shown in clotted outline at c. It will hence be seen that by setting the screw 0 the movable portion 0 may be caused to jam upon the threads of said screw D and thereby fix the same securely in position. The parts being in their normal position, shown in Fig. I, with the screw D adjusted so as to allow the required opening of the outlet a and with the piston .in its customary lower position, that is, not in contact with the lower end of the screw D, it will be seen that communication between the outlet 0? and supply pipe F is cut oil. The oil now being forced through the pipe under pressure, passes through the open check valve it, through inlet a into the chamber in cup A formed by the face of the piston 13 and the walls of the cup and raises the piston B, so as to remove the valve from its seat, thereby permitting the oil to tlow through the outlet a and so reach the hear ing to be oiled through the medium of the bore a". Upon removal of such pressure the piston and valve are returned to their normal positions by the action of the spring E. The grooves a are formed for the purpose of offering obstruction to the passage of oil between the contiguous surfaces of the piston and oil cup. It is not necessary to cause the piston to fit the cup so as to be oil tight, and a slight leakage between said surfaces is not objectionable so long as such leakage does not exceed the least quantity of oil required for the hearing. The oil so passing or leaking into the upper portion of the cup passes through the bore 5 and so to the bearing.

When it is desired for any reason to detach the supply pipe F, the coupling (T is removed, thereby permitting the detachient of the ends of the pipe F andnipple a Immediately upon the recession of the pipe F, nipple a and valve carrier H, the pressure of the oil within the pipe will force the valve hf upon its seat, thereby closing the end of the pipe and so preventing the leakage or discharge of oil theretorm. The oil under pressure is admitted into the pipe F by means of a suitable cock or valvewhenever it is required. The tension of the spring E is made such that it willovercome the resistance of oil in the cup, when said cook or valve is closed and the pressure so removed, the valve-opening into the top of the projection a." bein so closed by valve 6.
