Abstract

519,267. Thrust bearings. SMITH, J. W. Oct. 11, 1938; No. 29450. [Class 12 (i)] [Also in Group XXXIII] A screw propeller blade having a shank of tubular form is flanged externally and said flange has a plane surface and also a bevelled surface whereby it may be used for variable or fixed pitch mounting. The hollow root 7 is provided with a flange having a plane surface 11 adapted to carry a roller thrust bearing for action with the flange 3, 3A on a two-part hub when mounted so as to be adjustable for pitch. The thrust bearing comprises a locking ring 12 and oil seal ring 13, a bearing ring 14, a roller retainer 15, a locking ring 16, a bearing ring 17 and a locking ring 18. When the blade is fixedly mounted in a hub the bevelled portion 22A and the flat portion 11 of the flange are held directly between corresponding surfaces upon the two-part hub. Reference has been directed by the Comptroller to Specifications 293;307, [Class 114], 372,524, 380;812 and 487,084, [all in Group XXXIII].
