Abstract
626,777. Forcing liquids by air pressure; diaphragm air pumps. WALDRON, P. B. April 17, 1947, No. 10172. [Classes 8(i) and 102(ii)] In a sprayer of the knapsack type in which the liquid is forced by air pressure supplied by a diaphragm pump, the diaphragm b<SP>1</SP> is actuated by a lever a<SP>2</SP> secured to a shaft a mounted in one or more bearings and fitted with an actuating member that is slid or placed in the shaft and secured by a fixing pin &c. As shown, the c' is fixed by a screw c<SP>3</SP> and carries a cranked arm c having a nose c<SP>2</SP> that engages a socket b<SP>3</SP> carried by the diaphragm. Alternatively the arm c has a pin that engages a hole in a member carried by the diaphragm or the arm is slotted and engages a groove on the member carried by the diaphragm. In another construction a cam is fitted to the shaft and engages a forked member carried by the diaphragm.
