Abstract

707,083. Compressed air engines; vacuum engines. LUCAS (INDUSTRIES), Ltd., J. Sept. 5, 1952 [July 13, 1951], No. 16705/51. Addition to 683,145. Classes 122(1) and 122(3) The pneumatic motor of the parent Specification for actuating a windscreen wiper is modified by replacing the piston and cylinder by an axiallycollapsible and extensible chamber a secured at one end to the valve plate c and housed in an enclosure g secured in an air-tight manner to the valve plate. At its other end, the chamber a, which is made of rubber and reinforced by wire rings b, is attached to a pair of metal plates d secured to one end of the piston rod e adapted to actuate the valve mechanism f. In operation, compressed air or vacuum is admitted alternately by the valve mechanism to the interior or exterior of the chamber a. communication with the interior of the enclosure g being effected by a pipe h.
