PUMP-FEED OIL .(AN.

Application filed February 14, 1924. VSerial 310.692,63?.

This invention relates to -a lubricating can embodying a pump for ejecting the llubricating oil.

It is an object of this invention to provide a lubricating or oil can embodying a pump by means of which the oil can be readily ejected for oiling bearings no matter in what position the oil can may be held, whereby bearings in difficult or not readily accessible places may be lubricated.

The invention comprises the novel structure and combinations of parts hereinafter described and more particularly pointed out and defined in the appended claim.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the dif ferent views. j

Figure 1 is an elevational view of a lubricating can embodying this invention.

Figure 2 is an enlarged sectional view through the can.

Figure 3 is an enlarged fragmentary detail view of certain features.

Figure 4 is an enlarged sectional view upon the line 1 4 of Figure 2.

Referring 'to the drawings which illustrate one embodiment of this invention, there is shown an oil can embodying a lubricant con tainer or body portion 1 provided with cover or closure 2 having the usual nozzle 3 projecting therefrom. The cover may be attached to the container in any well known. way.

An oil feed pipe 4 is secured interiorly of the lower end of the nozzle in any approved manner. This pipe extends at a slight angle to the center of the nozzle to a point adjacent the bottom of the container. A valve housing 5 is attached to the lower end of the pipe L1. This valve housing has a longitudinally extending passage 6 therethrough, one end of which is closed by a screw threaded plug 7 the opposite end being provided with a valve seat terminating in a restricted opening; a ball valve 8 normally closes this restrict-ed opening through the medium of a coil spring 9 positioned be tween the ball and plug 7. The housing` 5 has a passage communicating with the pipe et. This passage is normally closed by a ball valve 10 seated in a conical recess in the upper side of the housing. A stop device 11 in the form of a hollow or apertured square nut necessary to reciprocate 'the piston, the air or the lilre is secured in the pipe 4L just above the ball 10, to limit its upward movement. The valve housing 5 is provided with another passage 12 in its top, and a pump cyl inder 13 is secured in said housing over said 60 passage 12. This cylinder is normal to the valve housing, consequently it will extend at an oblique angle to 'the vertical axis of the can. This cylinder projects through the cover or closure 2 and is firmly closed by a cap 14. A piston 15 is mounted for reciprocation in said cylinder and is provided with a handle 16 projecting through thecap 14. 1t will be noted that by arranging the cylinder 13 at the aforementioned angle, the handle 16 will extend at an angle to the nozzle 3 so that the same may be readily oper ated. A coil spring 17 is positioned between the piston 15 and the top of the valve housing 5 and is normally effective for return-- ing the piston to its uppermost position.

The oil can is provided with a handle 18 and thumb ring 19 adjacent the piston han` dle 16 so that the same may be actuated by the hand 'that is holding the oil can.

Assuming the parts in the position shown in the drawing, with a supply of oil in the can, the oil will enter the valve housing and rise in the tube or pipe 4 according` to the height of the oil in the can; the spring 9 being very sensitive so that the ball valve 8 will be readily pushed inwardly for opening` the entrance port. Accordingly when it is desired to eject the oil from the can it is only pressure exert-ing outward force against the ball valve 8 to close the entrance port and upward force against the ball valve 10 to open the valve passage controlled thereby. Consequently the air pressure will be effective for ejecting the oil through the nozzle 3.

Frein the foregoing it will be apparent that a very handy oil can has been provided from which the oil can be ejected or pumped in any position of the can, whether the same is in an upright vertical position or in an inclined position. It will also be evident that the pumping apparatus is solely sup ported by the closure 2 and is removable therewith, thereby facilitatingthe use of the can and the ease of manufacture.

l am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

An oil can comprising a lubricant container, a removable cover therefor, a nozzle mounted thereon, a pump mechanism mounted on said cover and projecting into said container, an inclined Valve housing supported I by said pump mechanism and open at both ends, a plug closing the lower end of 'the valve housing, a spring controlled intake Valve for closing' vthe upper end of said Valve housing, an outlet Valve in the side of said Valve housing, said valve housing having an openingVV in the side thereof communicating with said pump mechanism, and a pipe eX- tending from said nozzle to said Valve housing for enclosing said outlet valve.

In testimony whereof I have hereunto sub* scribed my name.

GUSTAVE LIDSEEN.
