Abstract

543,385. Toothed gearing. ANDREW, H. J. June 16, 1941, No. 7615. Addition to 534,348. [Class 80 (i)] [Also in Group XXII] The rotary frame mounting the epicyclic gearing described in the parent Specification is mounted in a hollow pulley or gear wheel. The sun wheel g is keyed on the fixed spindle c and meshes with the wheel h of the epicyclic train g, h, i, j, k, l, m, n the wheels h and i, j and k, and l and m being respectively integral and all the wheels except m and n being elliptical.
