Abstract

425,325. Fluid-pressure reciprocating motors. GRAY, W. T., Darroch, Wainwright Road, Altrincham, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 20, 1933, No. 29111. [Classes 122 (ii) and 122 (iii)] A reciprocating motor operated by compressed air or gas or vacuum, comprises a doubleheaded piston which reciprocates in a closed cylinder. The fluidpressure inlet and exhaust are controlled by two-way lift or ball valves operated by the piston at the ends of its stroke. The valves are associated with diaphragms which maintain them in an exhaust position until the pressure in one end of the cylinder is destroyed upon the piston reaching the other end of the cylinder. The cylinder 1 contains a double-headed piston which through an arm 5 oscillates a shaft 6 connected to the wiper. The inlet and exhaust to the cylinder ends are controlled by double cone valves 14<a>, 14<b> which are biassed to the right and left respectively by springs 15<a>, 15b, and alternately put the chambers 10<a>, 10<b> to pressure and atmosphere by pipes 7 and passages 13<a>, 13<b>. The ends of the cylinders are connected by pipes 11<a>, 11<b> to the chambers 10<a>, 10<b>. The valves are operated through springs by tappets 21<a>, 21<b> on the piston heads, which engage the heads of plugs mounted on diaphragms 16<a>, 16<b>. The cylinder pressure on either diaphragm holds the adjacent valve in the exhaust position until the cylinder end is put to exhaust. Flanged discs 22<a>, 22<b> limit the piston movement. In a modification, ball valves replace the double-cone valves, and the pipes 11<a>, 11<b>, 7 are contained in the structure of the motor.
