Abstract
A manually operable water well pump includes a baseplate with a casing thereon, a rocker arm pivotally mounted in the casing for reciprocating movement therein, a chain on one end of the rocker arm outside the casing for reciprocating vertical movement with the rocker arm, a connector on the free end of the chain for connecting the latter to a pump rod, whereby the rod can be reciprocated in a well casing, the transmission in the casing including a pair of gears interconnected by an endless chain, a crank for rotating the smaller of the gears and a linkage between the larger of the gears and the other end of the rocker arm for reciprocating the latter, and a tank suspended from the baseplate concentric with the pump rod for mounting on a well casing to receive and discharge water from the well.
