Title: Improvements in gear devices for conveying rotary motion
IPC: F16H37/00
Filed: 1932-01-28
Abstract: 393,021. Differential-gear device. SAVAGE, L. G., Royal Aircraft Establishment, South Farnborough, Hampshire. Jan. 28, 1932, No. 2593. [Class 80 (i).] A differential-gear device is adapted to transmit power continuously and to be operated alternatively by hand. The device may connect a shaft 1, Fig. 1, driven from the crankshaft of a compression-ignition engine, to a shaft 8 which normally drives the fuel pumps, the pump shaft 8 being alternatively driven from a hand - crank 12 when the engine is stopped, for priming. The engine-running power drive passes from a pinion 5 to a wheel 6 and from a side gear 2 of a differential through an idler 3 to the other side gear 4 fast on the shaft 8. The idler 3 turns loosely on a stud 10 which supports a part worm-wheel 13 and is fast on a spindle 11 secured to the hand-crank 12. When the engine is running, the partwheel 13 and axle 11 are held fast by a mutilated worm 14 engaging the part-wheel 13. The worm 14 is displaced angularly to effect the timing control by advancing and retarding the pump shaft 8. The worm shaft 15, Fig. 2, is geared by a pinion 16 to an internal quadrant 17 connected by a spring latch 18 to a control lever 20 which is moved to adjust the timing. To prime the stopped engine, the latch 18 is disconnected from the suitably locked lever 20 and the quadrant 17 is turned by hand until a gap 22, Fig. 1, in the worm 14 registers over the part-wheel 13, which is thus brought against a fixed pawl 23, Fig. 2. The crank 12 is then turned and the idler 3 rolls round on the fixed gear 2 so as to drive the pump shaft 8 independently at twice the speed of the hand gear. To resume normal drive, the hand gear 12 is reversed so as to bring the part-wheel 13 back against the stop 23 and the quadrant 17 is returned by hand to the old phase position and there connected to the lever 20 by the latch 18. In a modification shown in Fig. 6, the worm 14 instead of being mutilated is adapted to slide on splines on its shaft 15. While the engine is running, the worm 14 is held in mesh by a spring dog 30 engaging an annular recess 31 in a sleeve 32 extending from the worm 14. Phase adjustment is effected by the timing- lever 20. To prime the stopped engine, the dog 30 is raised out of engagement by turning a cam 36 from a lever 37. On operating the hand gear, the worm 14 slides along the fixed shaft 15 out of engagement leaving the hand gear full scope. On reversing the hand gear, a spring 34 returns the worm 14 to normal position where it is locked for operative engine.

Title: Control device for the dredge-tube suspension cables of a suction dredger
IPC: B66D1/26
Filed: 1950-02-03
Abstract: 694,954. Dredgers. ATELIERS ET CHANTIERS DE BRETAGNE ANCIENS ETABLISSEMENTS DE LA BROSSE ET FOUCHE. Feb. 3, 1950. [Dec. 7, 1949] No. 2887/50. Addition to 662,345. Class 113 (ii). In a control device for the suspension cables of a suction dredger dredge-tube, as claimed in the parent Specification, the winding drum for the cable hoisting the knee of the dredge tube is driven in unison with the other cablewinding drums (the clutch of the parent Specification being eliminated), said firstmentioned drum being equal in diameter to the smaller sections of said other drums, and utilising a weighted pulley to take up slack which tends to form in the knee-hoisting cable. The latter cable passes through a tackle-block carried by the supporting arm 20, over a sheave 27 of the movable part 17 and a sheave 28 of the fixed frame 16 of the davit, under a movable sheave 76, over a fixed sheave 77, and a sheave 34 to the winch. The movable sheave 76 carries a counterweight 78 slidable between guides 79 and having an extension 80 to limit upward movement by abutment against a fixed part 81. To sink the dredge-tube from the fully raised position shown in dotted lines in Fig. 4, the counterweight 78 being in its uppermost position, the winch is walked back so that the movable parts of the davits swing to ease the tube overboard and thereafter the tube is lowered horizontally since all the winding drum sections are equal in diameter. When the knee arrives opposite the intake aperture in the ship's side, its downward movement is arrested while the cables relating to the other parts of the tube ride on to the larger sections of their winding drums so that the tube is tilted downwards. The kneehoisting cable continues to be paid out by its drum and the slack is progressively taken up by the simultaneous lowering of the counter weight 78. Conversely, on hoisting the dredgetube on deck, while the tube is returned from its tilted to its horizontal position the counterweight 78 is lifted to its uppermost position, and the tube is then lifted horizontally on to the deck.
