Abstract

310,818. Mayer, C. April 30, 1928, [Convention date]. Pumps with reciprocating and rotating pistons. -In a piston-pump particularly applicable for surgical purposes the piston 10 is given combined rotational and reciprocatory motions during which inlet and delivery ports such as 9 in the pump cylinder 1 are successively uncovered by grooves 19, 20 in the piston communicating with the working space 1<a>. The actuating mechanism mechanism shown comprises a crank 12 integral with the piston rod 11 and having a boss 14 carrying a cam roller 16. The cylinder 1 is of glass and is closed by a cap 2 connected by ribs 5 to an externally-threaded ring 3. A cylindrical member 18 screwed to the ring 3 carries a camgroove 17 engaged by the roller 16. The cap 2 is formed with bored nipples communicating with the ports 9 in the cylinder and serving for the connection of inlet and delivery tubes. In use the pump is held in the hand and the piston actuated, to inject liquids into or withdraw them from the body, by manual rotation of the crank. The Specification as open to inspection under Sect. 91, (3) (a) states that the pump may be made double acting, the cylinder closure and the inlet and delivery ports and grooves being duplicated at the actuation end thereof. This subjectmatter does not appear in the Specification as accepted.
