PUMP OILER.

Application tiled September 13, 1922. Serial No. 587,975.

To all whom t may concern.

Be it known that I, ERNEST R. SrMoNs, a citizen of the Dominion of Canada, and a resident of Wapella, in the Province of Saskatchewan, Canada, have invented a new and Improved Pump Oiler, of which the following is a full, clear, and exact description.

Thisinvention relates to improvements 1n pump oilers, and mgreparticularly to an improved oil cari from which the oil can be pumped'in any quantity and with the force desired, so as to inject the oil wherever needed, an object of the invention being to provide a device of the character stated in which a slight pressure of the thumb on the lever will function toeject the oil from the dev construction and arrangement of thumb lever.

operating mechanism which is convenient to operate with either hand while wearing ay mitt or glove.

A further object is to provide a device of the character stated, which can be easily and completely taken apart for cleansing or 1ns ection in a relatively short time and readi y assembled again for use.

With these and other objects in View, the invention consists incertain novel features of construction and combinations, and arrangement of parts, as will be more fully hereinafter described and pointed out 1n the claims.

In the accompanying drawings- Figure 1 is a view in longitudinal section illustrating my improved pump oiler.

Fi ure 2 is aview in transverse section on the line 2 2, of Figure 1.

Figure 3 is a fragmentary view in longitudinal section showing-the plunger in its lower position. l

1 represents an oil container having a handle 2 at one side, and provided with a screw threaded nipple 3 at its upper end through which the oil can be supplied to the container. Within this nipple 3 a pump cylinder 4 snugly lits, and projects into the container 1. This cylinder 4 has an annular flange 5 adjacent its upper end, and a union 6 engages over the flange 5 and is screwed onto the nipple 3 securing the cylinder in place and operating as a closure for the container, but permitting said parts to be readily taken apart as may be'desired.

At the lower end of the cylinder 4 the same is provided with a threaded boss 10 to which is attached a reduced inlet chamber 7 which communicates at its lower end with an inlet tube 8 having a screened lower end 9 adja-l cent the bottom of container 1. A coiled spring 11 is located in the chamber 7 and interposed between the boss 10 and a ball valve 11 which normally closes the opening 12 connecting tube 8 with the bottom of chamber 7.

A plunger bodv 13 fits the cylinder 4, and at its lower end is provided with a plunger 14 including the plunger leathers 14 and having a central removable tube 15 constituting an oil passage and acting as a coupling means between the sections of the plunger to hold the parts thereof together. This tube 15 communicates with an outlet chamber 16 to which latter an outlet tube 17 is connected and constitutes a spout.

The outer end of the spout 17 carries a conical casing 18 which has screw threaded engagement with a truncated conical casing section 19, the latter overlapping the upper end of plunger body 13 and preferably soldered, or otherwise secured thereto.

In the outlet chamber 16, a ball check 2O is provided normally closing the upper end of tube 15 and held in normal position by a coiled spring 21. On the upper outer end of the cylinder 4 a drip pan 22 is rigidly fixed, and is provided at one end with an angular link 23 which is engaged by my imvproved thumb lever 24. This thumb lever 24 is preferably composed of strong wire of general fork shape having its intermediate portion straddling the section 19 and engaging fingers or pins 25 projecting from opposite sides of the latter.

The ends of the wire are bent forming hooks 26 which engage the link 23 so that the latter constitutes a fulcrum for the movement of the lever. The free end of the lever 24 is located above the handle 2 in convenient position to be engaged by theathumb of the operator, and a guide link 27 is fixed to the container 1 and permits operation of handle 2 with one hand and with the thumb of the same hand exerts a downward pressure on the free end of lever 24. This causes a downward movement of the entire plunger body and plunger 14, which forces the oil between the check valves 20 and 11, upwardly, anda spring 28 located below the 'plunger 14 compels the plunger to move upwardly when pressure is relieved on the lever 24. This upward and downward movement'of the plunger will eject the oil as rapidly and with the force desired so that the container can be held in vertical position or in any ordinary position and force the'oil Wherever desired.

Various slight changes might be made in the general form and larrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A pump oiler, comprising a container, a handle-on the container, a pump cylinder removably secured in the container, a pump plunger movable in the cylinder and having an oil guiding portion projecting'out of the cylinder, check valves in the c linder, and plun er controlling the flow o oil, a drip pan xed to the cylinder outside of the container, a link on the drip pan, a thumb lever fulcrumed to the link and at its intermediate portion engaging the body portion of the plunger and having its free end located yadjacent to said handle.

Y A2. V1Lfpump oiler, comprising a container hivingga screw threadednipple'at its upper end, a pump cylinder projected through the nipple and having an annular flange engaging the nipple, a union screwed into the inipple and securing the cylinder in the conl jecting outside of the same, a plunger body fitting the cylinder, a plunger on the lower end of the plunger body, a coupling tube coupling the parts of the plunger together and providing an oil passage therethrough, a tube located within the plunger body and projecting beyond the same and communieating with said passage, a spring in the cylinder exerting upward pressure on the plunger, a thumb lever for forcing the plunger downwardly, a reduced chamber at the lower end of the cylinder and communieating therewith, and check valves for closing. said first mentioned passage and the inlet to said last mentioned chamber.

4. A pump oiler, comprisino a container, a pump in the container, a drlp pan having xed relation to the container, a link on the drip pan, a wire lever straddling the pump andhaving hooked ends engaglng the link, means on the container limiting the movement of the lever in one direction, and a handle on the container located in lclose proximit to the free end of the lever.
