Abstract

157,290. Sorel, M. E. D. Nov. 7, 1919, [Convention date]. Pistons, balancing laterally and reducing and equalizing wear of. -In order to prevent piston slap, an aluminium piston for an internal-combustion engine is provided with one or more continuous-rings b, of iron or steel, or other metal having a coefficient of expansion approximately the same as that of the cylinder, for example a ring b may be secured to the piston body at each end. The rings are of slightly larger diameter than the piston body and are secured in position during casting. In order to allow for expansion, slots c may be formed in the flange a<1> on the piston skirt. The Specification as open to inspection under Sect. 91 (3) (a) states also that the rings b may be screwed or pressed on to the piston body. This subject-matter does not appear in the Specification as accepted.
