NELSON J. TUBBS, OF LOUISVILLE, KENTUCKY, ASSIGNOR OF ONE-HALF TO \V. O. BRADLEY, OF LOUISVILLE, KENTUCKY.

OVERHEAD OILER.

Specification of Letters Patent.

Patented Aug. 21, 1906.

To all whom it may concern.-

Be it known that I, NELSON J. TUBBs, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Overhead Oilers; a'iicl I do 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. i

' This invention relates to-overhead oilingcans; and one of the objects of the same is to 4 improve oil-cans of this character by providing means for ejecting oil from a dischargetube at a point at a distance above the floor.

Another object is to provide an oil-can with a pump and valves which will force a quantity of oil from the reservoir intothe discharge-tube at each alternate reciprocation of the pump-piston to force said oil up through an outer discharge tube into an oilcup or oil-hole in machinery far beyond the ordinary reach of an oiler.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in Which Figure 1 is a perspective view of an overhead oiler made in accordance with my invention, and Fig. 2 is a vertical sectional view of the same.

Referring to the drawings for a more particular description of my invention, the nu- 'meral 1 designates the reservoir or container for the lubricant. Secured centrally within said reservoir is a tube or cylinder 2, at the lower end of which a valve-seat 3 is secured. Small openings 4 communicate with the reservoir through the wall of said valve-seat.

A gage 5, having its vert1cal members se-,

cured to the valve-seat, serves to limit the movement of a ball-valve 6, said ball-valve adapted to fall by gravity upon the seat. In one wall of the tube or cylinder is a valveseat 7, adapted to be closed by a ball-valve 8, The ball-valve is placed within a fitting 9, secured at the sideof the cylinder in an inclined position, and a spring 10 bears at one side against the ball-valve and at its other end against a tubular elbow 11, extending out through the side Wall of the reservoir or oilcontainer and having secured thereto a telescopic discharge-tube 12. This dischargetube is provided with a projection 13 near its hook-point for the purpose of opening the lids of the oil-cups, while the curved terminal end 13 of the discharge-tube is placed within. the cup. The telescoping sections of the discharge-tube may be extended or shortened to reach the required cup forreplenishing the same. A pump or piston designed to operate within the cylinder comprises a rod 15, having a leather cup 16 upon its lowerend and a reversely-dispbsed leather cup 17 near its upper end, said leather cups being secured in place by means of a tube 18, surrounding the rod 15, washer 19, and nut 20, as shown in Fig. 2. Connected to the upper end of the rod 15 is a pitman 21, the upper end of which is connected to an elbow-lever consisting of two members 22, pivoted at 23 upon-a pair of brackets 24, secured to'a plate 25, extending laterally at the top of the reservoir 1. The upper ends of said lever are connected by a handle 26, and the spring 27 is secured to a cross-bar 28, said spring extending down and having its free end bearing against the rigid portion of the casing in order to return the pitman or pump-rod to its upper position. A handle 29 is also secured to the upper end of the oil-can, and a filling-orifice 30 of usual construction is disposed between the two members ofsaid handle. A small pipe 31. connects the oil-reservoir with the dischargetube, and in said pipe is a cook 32. The pur- .pose of this construction is to permit oil to return to the oil-reservoir when the oiler has been used.

The operation of my invention may be de- This movement forces oil up above the ball 6, out through the valve-seat-of valve 8, and up through the discharge-tube. When the handle 26 is released, the spring 27 throws said handle outwardly and raises the pump rod. 1 This action lifts the valve from its seat and draws oil through the openin valve up withinthe cylinder. The reverse or downwardv movement of the pump-valves forces the ball 8 from its seat and the oil out through the discharge-tube. When the oilcan has been used, the discharge-tube can be telescoped within a small space, and the oil 0 below the r5 -'I claim-as new, and desire to secure by Letremaining in the lower portion of th e dis-- char e-tube can be run back into the reservoir by means of the cook 32. i

From the foregoing it will'be obvious that my overhead oiler is of comparatively simple construction, is reliable and .efiicient use, and for oiling cups or machinery" at a dlstance overhead is very convenient and desirable cip'le or sacrificing any of the advantages of this invention. I

Having thusvdescribed my invention, What ters Patent, is

2. Inan oilenya'n.ioil reservon', a cylinder Within said reservoir, apiston Within said 'cylinder, a telescopic discharge-tube, a compound valve adapted to alternately open. and close at the movement of the piston to draw -v"a-q1iantity of oil from the reservoir and force the same outthrough the discharge-tube, a handle, anelbow-lever for-operating the piston, and a spring for returning the 'elbow-lever to itstnormal position, substantially as described.

In testimony whereof 1 have hereunto set my hand in presence of two subscribing Wltw nesses.
