<p>498,825. Speed control of engines for ship propulsion. SULZER FRERES SOC. ANON. July 13, 1937, No. 19359. Convention date, July 14, 1936. [Class 114] [Also in Group XXVI] A control mechanism for engines of ships comprises a centrifugal governor l driven by the engine and a lever c connected by a link d to a lever e connected to the regulating means of the engine. The pin i on the lever c forms the fulcrum of the lever m connecting the governor sleeve n and the link q which is also connected to the lever e. The links d, q have slotted ends h, p respectively and the lever e is biassed in the direction for maximum speed by a spring k. Movements of lever c through link d cause speed variations and the simultaneous variation of the fulcrum i causes the pin o to take up a position distance s from the end of the slot p that is practically constant for all speeds so that should the propeller leave the water the engine speed increases by a substantially constant amount before the pin engages the link q and the governor moves the lever e against the spring k to reduce the motive power medium. In Fig. 4, the same object is achieved by arranging that the speed is varied by rotating the hand wheel r which engages the abutment u and engages left- and right-hand threads on the rods q, t. The pin w on the lever w engages a slot v in the rod q. In a further modification it is arranged that the hand lever varies the spring loading of the governor.</p> |
