Abstract

647,147. Screw propellers. HARTZELL INDUSTRIES, Inc. July 29, 1947, No. 20514. Convention date, Nov. 5, 1945. Drawings to Specification. [Class 114] A propeller blade is made from layers of cresol formaldehyde resin in each of which is embedded a layer of fabric. This fabric is of cotton duck, the warp threads being either parallel to the blade axis or slightly inclined to this axis and to those of the neighbouring layers. The layers are moulded together by heat and pressure.
