Abstract

205,590. Butler, G. H. C., and Reeves, A. July 26, 1922. Actuating-pumps by foot power; oscillating cylinder pumps.-In an oscillating pump comprising a cylinder and piston, one of which is displaced by a toggle disposed between and actuated by two pivoted levers, the toggle is connected to the movable element of the pumps by a stirrup coupled adjustably. The pump is mounted between the levers 1, 4, Fig. 1, the cylinder being pivotally connected with the lever 1 and the piston rod connected to the operating-toggle mechanism 5, 7 by the stirrup 10, Fig. 3, which has slotted arms engaging with the axis 5<a> of the toggle mechanism. When the lever 4 is depressed by the operator's foot, the stirrup moves over the outside of the cylinder and effects the working-stroke of the piston. The toggle mechanism forms a lazy-tongs which increases the movement of the piston for a given displacement of the lever 4.
