Abstract

2470. VojÓcek, L. Jan. 31. Paddle-wheels.-Relates to a paddle-wheel of the type described in Specifications No. 3122, A.D. 1868, No. 4366, A.D. 1878, No. 19,282, A.D. 1889, and No. 18,396, A.D. 1903, in which the paddles are rotated by gearing in such a manner that the whole system rotates about a central axis at a certain angular velocity, while each paddle rotates simultaneously in the opposite direction about its own axis at half the angular velocity of the system. The paddles 6, 7 are mounted equidistant from the shaft 1, and are rotated on their axes by toothed gearing o, 21, 22, 23, 24, the wheels 23, 24 being each of twice the diameter of-the wheel o. The plane of the paddles thus always pass through a fixed point on the circle on which their axes lie. The gearing is enclosed in a casing 20 which is rotated by the shaft 1. To steer the vessel, the position of this point is varied by rotating the casing 9 and the wheel o by means of the pulley 14. Several modifications and applications are described ; for example, the central shaft may be driven by an engine or turbine mounted co-axially with it, or by bevel-gearing at the end of an ordinary propeller shaft. Submarine vessels are fitted with horizontal piddle-wheels at their side for manoeuvring purposes, and ordinary vessels may be fitted with three vertical paddle-wheels at the stern. The number of paddles is not limited to two.
