Abstract
Abstract A combination air and hydraulic motor in which air under pressure is used as the primary source of power. Hydraulic liquid is used as an intermediate linkage between the air under pressure and a mechanically reciprocating arm. A spherical float acts as a coupling means to separate the air and hydraulic liquid and prevents undesirable admixture of air and liquid. Valve means for the air under pressure determines the direction of movement of the hydraulic liquid. Mechanical linkage joins the reciprocating arm and the valve means whereby the valve means is alternately shifted to move the hydraulic liquid in one direction and then the other in alternating fashion to keep the motor running.
