for forcing said pump out of its normal relation to said stationary body, and means for restoring said normal-relation. 3. In a pump as described, the combina- 5 tion with a casing, of a piston to operate in the cylinder thereon, inlet and outlet pas- sages leading to said cylinder, means for op- erating said piston, laterally extending lugs carried.by said casing provided with open- 10 wings extending therethrough, means for at- taching said pump to a stationary body, the free end of said means being so shaped as to fit into either of said openings, a driving member, means for normally releasing ,the 15 operative means of said pump from contact with the driving member, and means for forcing the operative means of said pump into contact with the driving member. 4.
