MAYER. PUMP OIL CAN. APPLICATION FILED MAY28.1920.

Patented Aug. 22, 1922.

PUMP on. CAN.

Application filed May 28,

Toallwhomii'mag concern: Be it known that I, MILTON MAYER, a c1t1- zen of the United States, residing at Burlington, in the county of Des Moines and cylinder on one strokeof the piston by direct .vide'an oil can in which the 'de livery'of oil pumpaction and then forced on the return stroke of the piston through the discharge pipe. 1 Another object of the invention is to prois under positive manual control so that any desired quantity of oil mayibe discharged from the can without liability of waste. I

Other'objects 'of the invention are to arrange thevvalves-in a horizontalposition so that, they will seatproperly and locate them adjacent the bottom of the oil reservoir so that they will always be primed by submersion in the oil; and'also to provide an oiler of simple but strong and durable construc'tion, efiicient in operation, positive in action and inexpensive to manufacture.

-With these, and other ends in view which will more fully appear in'the detail descrip tion'hereafter I have illustrated the invention in a selected embodiment in the accompanying drawings, in which- Fig. 1' is a sectional view of an oil can embodying my lIlVGiltlOIlj. I

-( Fig. 2 is a perspective view of one of the valves; and v i I F g-LB 1s a detall sectional view showlng a slight modification in'the construction.

' Referring-to thedrawings, 4 is the body ofthe oiler which may be punched out at 5 I ,to form a filling opening and its wall threaded to-receive cap 6. 'The'body may also be punched out at 7 and threaded toreceive the cap8 which secures'the spout 9 in place .onthe body. pump cylinder 10 and a :dischargecylinder 11 are engaged one withthe other adj acent their inner'ends and are disposed an'gularly' within the body. The

5 and is closed'by a screwcap 12, This l cylinder extends downcloseto the bottom of the body and a machined valve seat13 havlng an opening 14 therein is soldered or otherwise suitably secured in the lower end of the cylinder. A valve 15' ground to snugly fitthe'seat 13" is normally held'seated by a spring 16 embracing the valve ,and' fas tened tothe seat. A piston comprising cups '17, 17 secured by

washers

18, 18 on the piston 19 is arranged to operate in the pump j" cylinder anda spring '20 is" arranged between the piston and the lower end of the discharge cylinder 11- which projects into the pump" cylinder above the valve 15.?fA seat 21 similarto'the seat 13" is securedin the lower end of the discharge cylinder 11 and is provided with an opening 22' A ground valve 23 isjheld against theseat 21 by a spring 24, the construction'of theitw o valves being preferably cthesame; The

springs

16 and 24 may" be secured to'theirrespective seats by solder; by welding or'by' .anyother suitable means: Afh'ollow core 25 is arrangedinthe dischargecylinder 11. A suitable handle2 6 is securedto the body.

' In the construction of Fig; 3jtli'at part 27 of the discharge cylinder 11" which enters the pump cylinder 10" is bent downwardly and the valve seat 21 is-secured to this down-turned part and to the pump cylinder.

In operation the 'pump'cylinder is filled on the suction stroke of the piston induced by the spring 20: during which the valve 28 is closed and valve 15 is opened- To screen the oil in filling the oiler I provide a perforated disk or screen 28 of foraminous metal which is secured in place at' the bottom of the-filling openingo in a pcripheral notch or bead 29 formed in the wall of said opening. When the piston is depressed by pressure applied to the'piston rod valve 15 remains closed and valve 23 is opened to permit discharge through the pum cylinder and the spout ofthe oil whic -has been drawn' 'up ll'ltO'ftl'le pump cylinder. -The quantity of 'oil discharged can be easily controlled'fbythe operation of the piston and in this way waste of'oil'is avoided.

I prefer to make peripheral flanges 15"and 23 thereon ground to fit the machined seats but the each of the valves'io :1- and 23 in the form of a hollow conewith construction of these valves may be I changed, if desired, and the

seats

13 and 21 may be provided and secured in the cylinders in other ways within the scope of my invention. The valves fit the seat snugly and both are substantially parallel with the base of the oiler so that in the normal travel ofthe automobile or truck in which the oiler is stored flatly on its base, and the vibration incident to such travel, the valves will not slide on their seats or become dislocated therefrom andtherefore undue wear and leakage are avoided. Eachvalveinakes a surface contact with its seat, and nota line'contact, and thereby provides an effectual seal which is especially desirable. in an automobile oiler which is constantly subjected to vibration during the travel of the automobile Both of the valves are located closely adjacent to the bottom of the oiler so that they will be submerged the oil. and primed for a greater length of time thanis usual in pump oilers. The two valves are located in such close relationship that a yalve chamber is almost co1npletely eliminated whereby a high degree of efliciency is obtained since very little it any effort is wasted in exhausting the oil content of a large valve chamber which might belocated between the intake valve and the discharge valve. The hollow core orplug 25 in the discharge cylinder reinforces and strengthens the cylinder and the portion of the body in which the cylinder,

is supported and the connection with the spout; and it also to a material extent prevents access through. the cylinder to the valves and in this way serves as a protection against tampering and injuring the valves. My improved oiler is substantial in construction, eflicient in operation, and can be manufactured at comparatively low cost. The horizontal arrangement of the valves and their location closely adjacent to the bottom of the oiler is especially important because not only are the valves kept submerged and primed until the greater portion of the oil has been discharged but the location of the intake valve 15' is so closeto the bottom of the body 4 that practically every bit of oil in the oiler may be discharged. The particular arrangement of the pump and cylinder and the discharge cylinder with their lower ends interengagedand with their upper ends engaged with and seated in the bodymakes a particularly strong and substantial structure and one which is highly eflicient in pe t on-c a v I reserve the right to make all such changes n fhBflOllll; construction and arrangement of; parts of my invention as claims.
