Abstract

135,960. Wolinski, B. Dec. 9, 1918. Lenses, grinding and polishing.-A machine for grinding and polishing cylindrical lenses comprises two spindles j, k driven at the same speed and in the same direction through gearing p, q, r from a shaft s, and having similarly-placed crank-pins g, h at their lower ends adapted to.engage freely in recesses e, f in a member a. This member, which may be either the tool or the work, has a cylindrical surface adapted to engage the corresponding surface of the fixed member d, which may be the work or the tool: the member a is thus moved bodily round in relation to the member d.
