Abstract

124,253. Muirhead, J. A. March 13, 1918. Screw propellers. - A propeller comprises a skeleton metal framework core or shell having embedded or consolidated with it a plastic composition. The blades may have ribs A and perforations B, Fig. 1, or ribs A and straight or expanded slots C, Fig. 2, or may take the skeleton forms, mainly composed of wire, shown in Figs. 4, 5, and 6. The core may be formed with perforations, slots, or cavities for the reception of light supplementary fillings of wire-gauze, cork, inflated tube, &c. Various forms of bosses are illustrated. Figs. 10 and 11 show examples in which the plastic filling-composition is indicated at K
