Title: Apparatus for Electrical Control of Motors.
Inventor: HILL GEORGE HENRY
Filed: 1902-11-11
Granted: 1903-02-19
Abstract: 24,770. Hill, G. H. March 25, [date applied for under Patents Act, A.D. 1901]. Motors. controlling.-Relates to the control of the motors on electrically - propelled cars by successively - operated electromagnetic switches controlled from a master switch in a multiple-unit system. The arrangements are such that the magnets are operated successively in proper order, and are automatically controlled by the current in the motor circuit. The magnets are included in two circuits from the master switch, one for actuating and the other for maintaining the switches closed. The cutting-out of the resistances is determined by the position of the master switch, but the proper progression through series to multiple relation is effected even if the master switch is thrown immediately to the full multiple position. In the general diagram, Fig. 1, there are four electromagnetic switches A, B, C, D with contacts to bridge the resistances in the motor circuit, two switches S, M which effect the series and parallel relations of the motors 1, 2, one switch L which opens and closes the motor circuit, one switch E which controls the circuits of the controlling-magnets, a throttle magnet coil F, reverser switch electromagnets G, H, and the master switches K, P connected to the train wires. The switches A, B, &c. not only cut in or out the resistances but are provided with other contacts, which open and close the actuating and retaining circuits for the successive magnets, and these contacts are carried by insulating-blocks on their plungers. If the switch K, for instance, is thrown to the full multiple position, the reverser switch and the switch L are first operated, and then the series switch S, after which the resistances are cut out one by one. The multiple governing - magnet E interrupts the maintaining-circuits of the controlling-magnets A, B, &c., thereby throwing in the resistances and open-circuiting the motors before the multiple position switch M is actuated and the resistances again cut out step-by-step. A modification is also shown in the Specification whereby the break in the motor circuit between the series and multiple relation is made at both the switches S, L, instead of at S only. Instead of separate resistance bridge contacts for the switches A, B, &c., the rheostat cylinder may be used and worked by ratchet gearing, or the rheostat may be worked by a pilot motor.

Granted: 1903-08-27
Abstract: 12,502. Osborne, C. T. June 2. Vapour engines. - Relates to motors for road vehicles &c. Figs. 1 and 2 show a plan and an elevation, respectively, of one arrangement in which a gas or other explosion motor A drives the shaft A<3>, from which the power is taken by a sprocket-wheel A<6>. A crank C<6>, on the other end of the shaft, drives an air, ammonia, or carbonic-acid compressor C, which supplies a reservoir C<5> by means of a pipe C<4>. From the reservoir, the air or other gas is conveyed by a pipe, having a throttle valve D<7>, to an engine D, driving a crank opposite to the crank of the explosion engine. When the pressure in the reservoir reaches the required limit, the valve E<1> is opened, the gas enters a controlling device, and, by raising a diaphragm, closes the regulating-valve of the gas motor. The crank shaft is driven then by the engine D alone. Before starting, pressure is raised in the reservoir by means of a hand-pump or otherwise, and the compressed air or gas is then supplied to the engine D. Should the engine D be unable to effect a start, the compressor C may also be used as a motor, by rotating the valve H. This valve cuts off communication between the delivery valves C<3> and the reservoir, and admits air or gas through the pipe L to a distributing-valve. The compressor may also be used as a motor in ascending steep grades &c. The engines C, D are provided with reversing-links or other reversing-gear. Their cylinders are preferably cast in one piece, or are fitted close together so that the heat of the compressing-cylinder prevents undue cooling of the compressed-air or gas engine cylinder. The exhaust from the compressed-air engines is conveyed to a jacket surrounding the gas-engine cylinder, and the exhaust from the gas engine may be discharged under the compressed - air engine to assist in beating it.

Granted: 1904-06-02
Abstract: 12,745. Morrison, A. M., and Maclachlan, A. M. June 6. Lifts; overwinding, preventing.-In a switching- apparatus for controlling electrically-driven hoists, the motor starting or resistance switch and the motor reversing - switch are operated by cams p, o, Fig. 1, on a hollow sleeve f<1> which carries also the pulley g to which the controlling-rope h is secured. When the sleeve is rotated from the position shown in Fig. 3 in either direction, the reversing-switch is closed and a weighted rack q allowed to fall so that a pinion r is rotated and the resistance switch properly operated to start the motor. During the working of the hoist by the motor, the main drum shaft a drives a shaft l within the sleeve f through an internal wheel e, a pinion j turning on a stud on the cup f, and a pinion k on the shaft l. A clutch nut m is thus traversed along its guides until, when the hoist reaches the end of its travel, it engages with one of two fixed clutch-pieces n; the shaft l is then stopped, and the sleeve f<1> rotated to stop the motor. The cam o may be replaced by a motorreversing drum carrying two insulated conducting- strips upon which four stationary brushes bear to complete the motor circuits for forward or reverse driving. The rope h may be replaced by or used in conjunction with two solenoids arranged in connection with the cam o and controlled by a hand-switch in the cage or lift. A ratchet andpawl escapement may be used to retard the falling movement of the rack q and to ensure a slow operation of the resistance switch.

Abstract: 15,591. Carolan, E. A., [General Electric Go.]. July 14. Sparking, preventing. - Consists of means for preventing arcing between the commutator brushes of dynamo-electic machines, particularly railway motors. A shield F, Fig. 3, preferably of fused non-porous silicious matter such as silicious sand or silica, or else of silica cemented by clay into fireresisting bricks, or of asbestos and cemented materials, or other non-combustible, heat-resisting, non-disintegrating, insulating substance, is placed between the brushes E, being secured by means of a projecting lug to the frame or casing of the machine, or resting on the commutator itself in some cases. When the brushes are 90‹ apart, a single shield is used, being placed in the quadrant between the brushes. Fig. 4 shows a plurality of shields F", F<111>, those F" above the line of commutation being held by clasp-like holders I, and those F<1>Jl below being held by wires, parallel to the shaft axis, fitting into grooves in the shields. This renders adjustment for the wear of the commutator, and of the shields, if they are in contact with the commutator, easier. In the case of motors intended to rotate in one direction only, comparatively small shields are used, one immediately in advance of each brush in the rotation direction, the machine being designed so that the magnetic field tends to drive the arc in this direction.
