Abstract

144,089. Mortier, G. A. June 4, 1919. Actuating pumps by foot power; pump-actuating mechanism.-An air-pump for tyre-inflation &c. comprises a frame formed of four jointed arms and having attached at one pair of opposite joints rods carrying respectively the barrel and piston, the pump being actuated by traction applied to the sides; the return stroke may be effected by spring action. As shown, the piston-rod 3 and a rod 2 on the end of the barrel are formed with forked ends pivoted on the opposite joint-pins 8, 10 of a frame formed of L-shaped pieces 4. Rods 12, 14 are provided on the other joint-pins carrying respectively a suspension ring 13 and a stirrup 15 depressed by foot or otherwise against the action of a spring 16 or a pair of springs on opposite sides of the piston rod. The apparatus may be used as a door-closing device, the rods 12, 14 being connected to the door and frame; a spring or chain may, in this case. form part of the rod 14.
