Abstract

163,033. Bell, A. G., and Baldwin, F. W. May 7, 1920, [Convention date]. Propelling by aerial propellers; rudders.-In hydroplane vessels, hydro-aeroplanes, &c. employing sets of submerged hydrofoils, the main side sets of blades 33, Fig. 2, and the engine casings 17 are supported and carried by truss constructions based upon transverse beams 11, 11<a> passing through the main cigar-shaped stream-line float structure 10. A duplex combined supporting and steering set of hydrofoils 18, Fig. 4, is centrally mounted at the stern on a vertical axis 34<1> disposed in front of the centre of pressure of the blades so that this set assumes automatically a neutral position. The blades are mounted on vertical and inclined side supports 35, 36, the upper blades being horizontal transversely and extending across from side to side; the lower blades 37<a>, 37<b> are divided and are inclined laterally upwards in an outward direction under the outer extremities of the horizontal blades. Side-decks 13, Fig. 2, of aerofoil form project laterally from both sides of the hull 10 and terminate in side floats 27. The aerial propellers 39 are preferably mounted directly on the motor shafts.
