REVERSIBLE PUMP OIL CAN'.
Application led March 16, 1923. Serial No. 625,523.
T0 all whom t may concern Be it known that I, EDWIN C. WOLFE, a citizen of the United States, residing at Corral, in the county of Camas and State of Idaho, have invented certain new and useful Improvements in a Reversible Pump Oil Can, of which the following is a specitication.
This invention relates to improvements in oil cans, particularly to the type known as a pump oil can and has for its prime object to provide a pump oil can which can be operatedfrom any position.
A further object of my invention is to provide an oil can of the above indicated character which is entirely automatic in operation, simple in construction in that same is composed of relatively few partsand so arranged that the can can be easily and quickly disassembled for the purpose of repair or replacing with new parts as the case may require, and one that can be manufactured and placed on sale at a relatively low cost.
rThese and like objects of the invention will be better understood as the description follows and as is specifically pointed out in the appended claims.
Referring to the accompanying drawings which form a art of this specification and which clearly i lustrate the construction and operation of my improved oil can,
Figure 1 is a side elevation partly in section of an oil can constructed in accordance with my invention.
Figure 2 is a similar view with a portion of the spout broken away, showing the oil can in a'horizontal position, and
Figure 3 is a similar view, showing the oil can in an inverted position.
Referring to the accompanying drawings in detail, like characters will be used to designate like parts inthe different views.
ln the drawings, the numeral 1 indicates the body or oil receiving chamber of my improved pump can. The body 1 is provided with a bottom 2 and a hand grip 3 attached to one side of same. In order to fill the receptacle or body 1, a removable cover 4 is provided which has a finger or thumb grip 5 attached to the top of same, right above the hand grip 3. It is to be understood that if can be formed integral lwith the body 1 and a cap screw positioned at any desired point on the cover d for filling the chamber 1.
'valve seat 11.
The cover 4 is provided with a central opening through which projects a neck'portion 6. The neck extends downwardly within the chamber 1 and is bent at right angles as at 7. A pair of tubes 8 and 9, which are arranged in the form of the letter V are formed integral with the right angle portion 7, and each of the tubes are provided with a stop pin 10 at a point adjacent the right angle bend 7, and each of the stops is provided with a central opening and ball The free end of each of the tubes 8 and 9 is covered by a fine wire mesh 12, for retaining in each of the tubes a ball valve 13. The upper end of the neck which projects through the central openin in the cover 4 is provided with externa screw threads as at 14 for receiving thereon av spout 15.
A cylinder 16 is welded or secured in any way to one side of the neck 6 at a point just above the cover 4 and the cylinder 16 has communication with the interior of the neck through an opening 17 formed in the neck. A. piston or plunger 18 is mounted in the c linder 16 and works against the tension of7 a coil spring 19 by exerting pressure against the plunger or piston button 20.
Positioned within the neck at a point above and below the opening 17 are ball valves 21 and 22, each of which is adapted tobe held against their respective valve seats 23 and 24 by coil springs 25.
When the oil can is being used in the position indicated in Figure 1, which is an up. right position, the piston 18 is forced inwardly inthe cylinder 16 against the tension of the coil spring 19, and then allowed to return to its original position by releasthe piston 18 retracts within the cylinder, the ball valve 21 is raised off of its seat against the spring 25 by means of suction, which withdraws the oil from the chamber 1 through the tube 8 into the compartment of the neck adjacent the cylinder and upon againfoperating pressure on the button 20, the oil forces the ball valve 22 ofi' of its seat and discharges the oil through the spout 15.
When the oil can is used in a horizontal the operation of the plunger is the same as described in Figure 1, and the oil within the chamber 1 is drawn through both tubes 8 and 9.
l`When using the position, the oil is pump can in an inverted drawn through the tube 9 ing the pressure against the button 20. As
bygoperatin the plunger inthe manner above descri ed. Y
In view of the foregoing description of my invention taken in connection with the laccompanying drawings, it is thought that bination and arrangement of parts.
I'Vhat I claim as new and desire to secure by Letters Patent is:
1. In an oil can, comprising an oil receiving chamber, a cover for said chamber, a neck portion adapted to extend through said cover and being provided with an extension extending downwardly within the oil chamber and being bent at right angles, pipes secured to the right angle bend and extending in opposite directions and terminating adjacent the top and bottom of the chamber and near the side Wall thereof, a ball valve positioned in each of the pipes, neck valves positioned in the neck portion, and a piston operable in the cylinder on one side of the neck portion for operating the ball valves and neck valves for discharging the oil from the can.
2. A reversible oil can comprising an oil receiving chamber, a cover provided for said chamber, a neck portion extending downwardly through the center of said chamberand being bent at right angles, a spout secured to ysaid neck portion and extending upwardly therefrom, V-shaped piping formed integral with the right angle portion of the neck, a stop pin arranged in said pipingl adjacent the right angle bend c and each lstop being provided with a central opening, and a ball valve arranged therein,
a cylinder formed on one side of the spout portion, a plunger rod extending into said cylinder and a coil spring arranged within said cylinder and spout portion, for dis charging the oil from the can:y
In testimony whereof, I have aflixed my signature in the presence'of two witnesses.
