Filed: 1939-11-30
Abstract: 535,631. Winches. BURNS, C., [Representative of BURNS, M.] Nov. 30, 1939, No. 31138. [Class 78 (v)] A winch particularly for manipulating ship's derricks, comprises a main drum 3 for handling the load and an auxiliary drum 33 for controlling the derrick. Both drums are driven from a power shaft 7 through gearing, that operating the auxiliary drum 33 including a non-reversing drive, such as a worm 30, whereby the derrick will be held in any position to which it has been brought when the power drive is disconnected. The drum 3 may be driven with one reduction only through gear wheels 16, 14, the pinion 16 being loose on the power shaft 7 and coupled thereto by a clutch 8 controlled by a handle 26. Alternatively the drum 3 may be driven with increased reduction by gear wheels 12, 11, 13, 14 of which 12 is loose on the shaft 7, 11 fixed on a lay-shaft 10 and 13 loose on shaft 10 but connectable thereto by a clutch 15, which is controlled by the handle 26 in such manner that clutches 8 and 15 are never in engagement simultaneously. The worm 30 is driven by bevel wheels 23, 24, the wheel 23 being on the sliding member of a clutch 9 by which the wheel 12 is connected to its shaft 7, the position of this compound member being controlled by a handle 22. Thus the drum 33 may be driven simultaneously with the drive of the drum 3 through the gears 16, 14, but not when the drum 3 is driven by gears 12, 11,13,14. In a modification an electric motor &c may drive the drum 33 through a non-reversing gear. An outboard drum 5 is also provided on the main drum shaft.

Title: Improvements in and relating to electric motor controllers
IPC: B60L15/04
Filed: 1926-12-10
Abstract: 262,809. British Thomson-Houston Co., Ltd.,.(Assignees of Hamilton, TV. S. H.). Dec. 10, 1925, [Convention date]. Series-parallel systems; regenerative systems; master-control systems.- In series-parallel rheostatic control systems the changes of grouping are subjected to restrictions according to the amount of resitance in the motor circuits and according to the stage of control in acceleration, deceleration, or regenerative braking. The invention is described in connection with a six - motor traction equipment provided with electromagnetic resistance contactors, and electromagnetic switches for reversing, changing the motor combinations, and braking. The contactors and switches are electrically connected to form master controllers, viz. :-RC for determining forward or reverse running, SC for determining the motor-grouping, MC for effecting acceleration and deceleration, and BC for regulative braking. The circuits are arranged so that the motors can be started at will from either series grouping, series-parallel, or full parallel, and accelerated by advancing the controller MC through the positions F1 - - P18. After passing the fifth accelerating notch, a controller segment 205 interrupts the. energizing circuits for the valve operating magnets of the group switch. If later the group selecting controller SC is moved, say from the series position to the series-parallel position, no change of grouping takes place at once, but a circuit is made through a relay R<1> which establishes temporary maintaining circuits for the resistance contactors, thus enabling the driver to bring back the controller MC to the sixth notch without affecting the motor current. The next backward step to the fifth notch serves the double purpose of interrupting the temporary maintaining circuits, thus reinserting the resistances, and of closing the circuit of the valve magnet 83 which effects the charge to seriesparallel grouping. Similar steps must be gone through in order to change from series-parallel to full parallel. For transitions in the converse order a relay R<2> is arranged so that the controller MC pust come back to the sixth notch and then go forward to the fourteenth notch, thus ensuring that some resistance is in the motor circuit when the transition takes place. In regenerative braking transitions can only take place after the controller BC has been brought back to the zero or motoring notch and the controller MC to the first notch. Arrangements are made for varying the sequence of resistance contactor operation according to 'the motor grouping, in order that similar notching-up steps may correspond to similar changes of the motor torque. To facilitate manipulation, the driver's handle of the controller MC is fitted with forward and backward stops coupled to a spring-pressed thumbbutton.
