Abstract

111,743. Podiebrad, B., and Freeman, P. Jan. 3, 1917. Portable hand-pumps; actuating pumps by foot power.-In a pump for inflating tyres &c. of the kind comprising a horizontal cylinder A, a pair of short links pivoted at one end to the frame B and at the other end to a pair of long links F carrying a pedal M, the links F embrace the barrel A and are each connected to the plunger by a pivot pin passing through a slot in the barrel. A plate J may be pivoted to the underside of the pump so that it can be turned into the position shown when the pump is in operation. A catch K may be provided to engage a pin L on the links F to lock the links in the horizontal position. The links F are rigidly connected by a pin G, which serves as a pivot for the links C. A spring G' on the pin effects the suction stroke.
