MATIIIAS J OLLY, OF TROY, ASSIGNOR OF TVVO-TIIIRDS TO MARGARET P. THAYER, OF LANSINGBURG, AND MYRTIE E. HART, OF TROY, NEV

YORK.

OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 433,244, dated. July 29, 1890.

Application filed May 10, 1889. Renewed June 30,1890, Serial No. 357,184 (No model.)

To all whom it may concern.-

Be it known that I, MATHrAs JOLLY, a resident of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, referencebcinghad to the accompanyingdrawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in oilcans and it con sists in the novel construction and combination of parts hereinafter described, and pointed out in the claim.

Figure 1 of the drawings is a central vertical section of my improved can and the enlarged pump-chamber, the pump-tubes being shown in elevation. Fig. 2 is a central vertical section of the pump-tubes. Fig. 3 is a top plan view of the perforated drip-guard detached from the inner side of the perforated can-cover. Fig. i is a horizontal sect-ion Fig. 5 is a side elevation of the pump-plunger detached from the pump-cylinder. Fig. 6 is a central cross-section of the two disks forming the piston,riveted together and detached from the other parts. Fig. '7 is a central vertical section, on an enlarged scale, of the pistonhead, guide, concaved valve, valve'stem, and

piston stop fixed thereon detached from the tubes.

The can A is shown provided with a depression or sink A in its cover, which has a central drip-openin g A and with a pump located near the periphery on one side of the can, havin g a nozzle A projecting over the sink A. The nozzle is secured to the enlarged chamber-case B, and the case is fixed upon the pump'cylinder 13 which is rotary in and movable longitudinally of the tube 13 the tube extending in a fixed position from the top to the bottom of the can, as shown in Fig. 1.

\Vhen it is desired to fill a lamp, the nozzle is lifted until the lamp can be deposited in the sink upon the can-top. The nozzle is then low ered and swung around until it enters the filling-inlet of the lamp, after which the pump is operated to fill the lamp in substantially the manner heretofore employed an d well known. The central perforation A permits any overflow to pass down through and drip into the can. During the transportation of the filled can so perforated the oil islikely to be forced violently out of the perforation unless the same is protected. I provide as such protection a small cap or drip-guard A, which is provided with small perforations A in the vertical walls of the guard, and may have an attaching-flange A, by which it is soldered to the inner surface of the can-cover. as shown in Fig. 1.

The pump piston, which is adapted to slide in the cylinder 13 and upon the valve-stem P, has a novel form of construction, is cheaply constructed, and durable. The piston is pro- 'vided with a central aperture P, made considerably larger than the valve-stem, to receive such stem and at the same time permit of the passage of the desired amount of fluid. I have shown the piston made of two centrally-perfo rated disks 1 and P secured to each other by a hollow rivet P, passed through their central perforations, and of a sleeve or piston-guide P adapted to slide upon the valvestem. The piston-guide is secured to the piston-head by soldering it to the small upper disk, which may be made of copper, tin, or other material to which solder will readily adhere, while the lower disk P which is required to do the work of a piston, may be made of cast-iron or other metal. I have shown the guide secured to the upper disk by a series of downwardlyprojecting teeth P, which can be easily soldered to disk P Any desired number of teeth or arms, as three in the form of a tripod, may be employed.

The valve-stem is provided with the valve P fixed upon its lower end. This valve is preferably made of a concaved piece of sheet metal adapted to inelose the rivet P and be seated upon the lower side of the disk to close the central piston-aperture. The stem is also provided with a stop P fixed thereon, and at its upper end with an operating-handle P", also with the stops P and P hen the too stem is given a Vertically-rcciprocating moing the downward movement of the piston by the check-valve P in the bottom of the cylin- (ler, which may be any known form of checkvalve. The stops P and P limit the movements of the valve-stem to short strokes, making it well nigh impossible for the operator to pump the fluid into the chamber B faster than it will run from the nozzle, thereby preventing its running over the top through the stem-aperture. At the same time the operator can easily pump fast enough to keep the chamber filled above the nozzle-outlet, thereby producing a comparatively steady stream of the fluid therefrom.

O is a packing-box secured to the fixed tube 13 This box is filled with packing O, forming a tight joint around the vertically-reciprocating cylinder B The box is screw-threaded and adapted to receive the correspondinglythreaded cap 0 I do not claim any invention in the dripopening and guard.

WVhat I claim as new, and desire to secure by Letters Patent, is

The combination, in a fluid-can pump, with a concaved valve fixed upon the end of a reciprocatory stem, of a centrally-perforated piston-head formed of two centrally-perforated disks, a hollow rivet inserted in such central perforations to connect the disks with each other and form a central slideway for the valve-stem reciprocatory therein, a piston- 45 guide secured to one of such disks and provided with a central slideway for the stem, and a stop P fixed upon the stem, substantially as described.

In testimony whereof I have hereunto set 50 my hand this 7th day of May, 1889.

MATHIAS JOLLY.
