Abstract

455,074. Air - screws. ELLIOTT, A. G., Holmwood, Quarndon, near Derby, and RUBBRA, A. A., Red Roofs, Carlton Road, and FAIRHURST, L. G., 57, Lindon Drive, both in Derby. March 8, 1935, No. 6917/36. Divided out of 455,044. Drawings to Specification. [Class 114] Air-screws with hydraulic pitch varying mechanism are constructed with an external hydraulic cylinder carrying rods which slide in sleeves in the hub and are linked to inwardly projecting pins on the blade roots. The particular description is identical with that in Specification 455,044.
