Title: Improvements in Electric Cranes.
Filed: 1903-11-03
Granted: 1904-06-02
Abstract: 23,851. Stothert & Pitt, and Pitt, W. Nov. 3. Cranes.-Consists of means for sustaining the load in an electric crane in case of the current failing, and for preventing overwinding. Loose on the brake treadle shaft A is an elbow-lever, of which one arm B engages an arm H fast on the shaft, and the other arm D normally rests against a trigger E, held in position, against the action of a weighted lever F or spring, by a solenoid in the motor circuit. Thus should the current fail, the trigger E is released and the weight C applies the brake. To prevent overwinding, the lever F is connected to a cord M running along the jib, and so arranged that if the load be overwound the cord is pulled and the trigger E released. A dashpot L prevents the too sudden application of the brake.

Title: Improvements in Controlling Alternating-current Electric Motors.
Filed: 1904-02-26
Granted: 1905-01-05
Abstract: 4771. British Thomson-Houston Co., [General Electric Co.]. Feb. 26. Motors, controlling.-Repulsion motors are given a larger torque near synchronism, and are made less liable to race on light loads, without diminishing the torque, by furnishing them with two sets of brushes which are inclined to each other by about 90 electrical degrees, and are also displaced from the line of magnetization of the stator. One set is short-circuited, and a variable voltage may be impressed on the other set by hand as in Fig. 1, or automatically as in Figs. 4 and 5. In Fig. 1, C is a transformer connected to the rotor R by a switch D so arranged that the maximum transformer voltage impressed on the brushes b<1>, b<1> in the first position of the switch D approximately equals the voltage induced in the rotor by the stator, so that, no current flowing into or out of the rotor, the motor starts as an ordinary repulsion motor ; as the switch is moved over, the transformer is cut out section by section till, in the last position, only one section remains, and this is arranged to compensate the reactive effect of the magnetizing-current. The variable voltage may be obtained from the stator winding as in Figs. 4 and 5, by means of two or more taps m<2>, m<3> inclined to one another at less than 180‹ ; as at starting no current flows to or from the rotor, the motor may be started and the compensating- current switched in as synchronism is approached. An automatic device I, actuated by the current which flows from the primary winding to the brushes b<1>, b<1> when the motor speeds up, may be used to do this, or it may be done by hand. If the number of turns in the rotor differs from that in the stator, a transformer L may be introduced as in Fig. 5, and, as several motors may be operated from one switch, the system is particularly adapted for use on trains.

Title: Improvements in Electric Motor Control Systems
Filed: 1904-12-15
Granted: 1905-11-30
Abstract: 27,401. British Thomson-Houston Co., [General Electric Co.]. Dec. 15. Motors, controlling, - Relates to master-control systems particularly for trains on the multiple-unit system, and consists mainly of a circuit-breaker adapted to be opened at will or upon a failure in the control current but not affected when both control and power circuits are opened, as in the ordinary stopping of a car. Means are also provided for limiting the current that may be carried by the bus-lines connecting the several current collectors. Fig. 1 shows the general arrangement, which is similar to that described in Specification No. 13,721, A.D. 1900. In the present arrangement, separate connections are made from each master-controller to the collectors T, resistances 48 being provided in each connection. A branch 49 leads from each connection to the next car, as shown in Fig. 2. By this arrangement two resistances are interposed between the current collectors of adjacent cars, but only one in the control circuit. The circuitbreaker comprises an arm 50 attached to the core of a re-setting solenoid 52. It is held closed by a catch 56, which engages with a projection 57 forming one part of a toggle. The tripping- arrangement comprises a lever 64 adapted to be operated by an electromagnet in the power circuit in case of overload. A pair of electromagnets 67, 68 in the control and power circuits respectively actuate a lever 69, moving it parallel to itself when both magnets are energized or de-energized simultaneously. Should, however, the control current fail, the lever tilts, and strikes the lever 64, so releasing the catch 56. The circuit-breaker may be operated at will by means of a switch 70. The circuit-breaker is reset by momentarily closing the switch 61 when the controller is in the 'off' position, and is thus bridging the contacts a<5>-a<8> by special contact-segments, and when the motor controller is also in its 'off' position.
