UNITED STATES PATENT OFFICE.

OIL CAN.

Application filed May as,

This invention relates to new and useful improvements in oil cans and has for its main object a construction of can, wherein, mechanism is provided for automatically forcing the oil from the can.

Another object of the invention is the provision of automatic mechanism, the action of which can be readily controlled.

Besides the above, my invention is distin uished in the combination of manually coll apsible means for exerting pressure on the oil in the can in combination of a manually operating valve controlling the flow of the oil from the can.

lVith the above and other objects in view the invention consists in the novel features in construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and 7 shown in the accompanying drawings in which Fig. 1 is a vertical sectional view of my improved oil can.

Fig. 2 is a sectional view on the line 22 of Fig. 1.

Fig. 3 is a sectional view on the line 33 of Fig. 1.

Again referring to the drawing the numeral l designates a casing having a top 2 and removable bottom 3. The top 2 is provided with a neck 4 at the bottom of which is arranged a flange 5. A removable valve member 6 is seated in the neck and rests upon the flange 5. This member 6 has a bore 7 and a valve seat 8. Associated with the valve seat 8 is a valve 9 attached to the 3138111 10 to the outer end of which is attached the button 11. A spring 12 acts against the button to hold the valve closed. The spout 13 of the oil can has a flange 14 engaging around the member 6 and is engaged by the ring 15, threaded to the neck 4.. Thus it will be seen that the spout and valve member is effectively held together and may be readily removed. For this purpose the valve stem 10 is composed of detachable sections as indicated at 16. Top is also provided with a filling cap 17 Slidable in the casing 1 is a plunger 18 acting against the body of oil in the casing. My improved manually controlled automatically operating mechanism for exerting pressure upon the piston and thereby subjecting the oil to a constant pressure consists of a control spring 19 of a collapsible formation having one end fixed to the piston as indi- 1924. Serial No. 716,503.

cated at 20 with the other end attached to the bottom 3. A spring pressing device 22 engages over a convolution of the spring and is operated by the crank element 23 mounted in the bearing 24. It will be readily apparent that by turningthe springpressed device 22, the spring 19 will be gradually collapsed in order to move the plunger 18 toward the bottom of the can for refilling the same and by turning the device 22 in the opposite direction, the spring will be gradually released, forcing the plunger 18 toward the spout 13 for dispensing the contents of the can. The rotation of this device causes the spring to be compressed under the device for moving the piston downwardly for revolving the can.

From the foregoing description taken in connection with the accompanying drawings it will be apparent that by opening the valve at the top of the can the spring action will force the piston forwardly for automatically forcing the oil from the can.

It is, of course, to be understood that various other types of operating devices may be used for collapsing and holding the spring during the filling operation and the valve device at the top of the can may be constructed in various other ways and associated with the casing in various other manners, and therefore, I do not desire to be limited in any manner except as set forth in the appending claims.

Having thus described my invention what I claim is 1. An oil can including a casing, a spout projecting from the casing, a plunger movable in the casing, a coil spring confined in the casing and having an end portion connected to the plunger and an opposite end portion connected to the casing, and a manually rotatable member within the casing and defining portions adapted to work over and along the convolutions of the coil spring for contracting and expanding the coil spring to move the plunger in reciprocatory action within the casing.

2. An oil can including a casing, a spout projecting from the casing, manually operated means controlling communication between the spout and the casing, a plunger movable in the casing, a coil spring confined in the casing and having an end portion connected to the plunger and an opposite.

end portion connected to the casing, and a manually. rotatable member, within the easing andidefining portions adapted towork over and along the convolutions of the coil spring for contracting and expanding the coil spring to movethe"plungerin reciprocatory action Within the casing. f 3.
