Abstract

21,320. Pinkert, G. Sept. 13, 1909, [Convention date]. Screw and like propellers. - Propellers for ships, air-ships, &c. comprise conical bodies k provided with metal, wood, or other blades a on their inner, outer, or both surfaces, which do not project beyond the vertices s or the circumferences of the bases p of the bodies. The blades preferably lie wholly in planes passing through the axis of the shaft, but they may be inclined to these axial planes. In the form shown in Fig. 16, inner and outer sets of blades a, which are in staggered relation, are used, the apex of the conical body being cut away to form an opening e, and the propeller is connected to its boss by radial arms o. The ends of propellers with outer blades only are preferably closed by conical caps. Two propellers for propulsion in opposite directions may be mounted end to end, the shaft of one of them passing through that of the other. The conical bodies may in some cases be of pyramidal form. The Specification as open to inspection under Section 91 (3) (a) comprises also the use of the propellers as ventilating-fans and pumps. This subject-matter does not appear in the Specification as accepted.
