Abstract

566,447. Pistons. JOHNSON, M. E. Aug. 16, 1943, No. 13253. [Class 122 (i)] In a piston for brake &c. cylinders operable under low pressure or vacuum and comprising a drum a, a packing member c having a peripheral lip c<1> extending over a portion of the drum, and a backing plate b, secured together by a bolt &c. d, the drum and backing plate are formed with rounded beadings a<3>, b<1> engaging the cylinder wall on opposite sides of the packing to obviate tipping of the piston. The headings may be notched to provide free communication between the packing and cylinder spaces. The wall a<2> of the drum may be tapered ; and the drum and plate b may be formed of synthetic resin. The flat portion c<2> of the packing seats in a recess e in the drum &c. is provided with a rib c<3> engaging a groove e<1>.
