Abstract

315,974. Blyth, C. E. June 25, 1928. Portable hand pumps.-A pump operating a motor horn comprises a pair of freely communicating telescoping hollow shells a, b mutually guided and limited in stroke by a plunger g on one shell which slides in and abuts against a collar h of a tubular guide sleeve i on the other shell. Air enters past a cup leather c and through a port m in the sleeve i. In a modification, the plunger g extends into the outer tube j and the plunger stem f is hollow for the passage of air.
