A ballivalive39ds held normally to saidv seat 37*by a spring 413, reacting against a tapered abutment llwhich is located within the spout. Said spout is mounted within a sleeve-like portion 42 of a closure member 43, which removably ens. gages the cup-like member 35.

If desired; the spout may beiprovided, witha disk 44 slidably engaging the bottom wall of member 35- sothat the-spout may: be; rotatable. (Sec Fi ure 3). This-would permit of the placingo a curved: spout in any desired position, should the position otgtl eclosure member 43 be variedL In practice, in assembling the parts, the pump casing 1 8 is set into the false bottom 12 through the flange 17 and then the false bottom and the main-bottom are manipulated into position. The slopingsidesof the false bottom allow the pump to be inserted into position so as to extend throughthe opening in the top of? the can bodyand also: so as to permit the feed tube 37'to' be inserted through the bottom of the: cupmember 35'. The bottom edge: of the can and: the two: members 12 and 13 are then rolled or pressed together and theedge of the opening through which the upper end of the cylinder extends is connectedwitlrthe edge 19 by-rollingor pressing them together. It is to. be understood, of course, that the member 35 has been previou ly secured in position in the neck of the can by rolling or similar means.-

With the parts thus assembled, the closure member 43 with-the attached spout 38 may be removedand the can filled with oilthrough the openings-36 in the bottom of. the cup-like member- 351, the oil passing through the perforat-ions 1? into the chamber 15. The

closure 43 and its attached spout are then I placed in position and the can is ready for use; It will be observed that as the piston 27 is depressed and then allowed to rise under the reaction of thespring126, oilis eventually pumped out of thechamber;15into1the-pump cylinder and then=ejected through the tube; 37 to the spout 38. The valve -23;acte as a check valveon the downward stroke-of 'the piston and the valve: 39- also acts'asa' checkvalve to be unseated by the f'orce: of the: downward strokeofi the piston.
