Title: Improvements in Forging Presses
Inventor: FIELDING JOHN
Filed: 1902-08-29
Granted: 1903-07-16
Abstract: 18,977. Fielding, J. Aug. 29. Forging punching; shearing; ; stamping.-Relates to presses in which the tool is lifted and brought down on to the work by steam, while the forging or other operation is effected by hydraulic pressure. Fig. 1 shows one form of press in which the slide A forms the hydraulic cylinder. When the hand-lever is placed in the position shown in full lines, steam is admitted below the piston I, which raises the slide A and the valve of the cylinder R. A pin V in the lever L lifts the valve E, to place the cylinders A, D in communication with the reservoir G, in which the water is at a pressure of about 30 1bs. per square inch. The lower end of the cylinder R is placed in communication with the exhaust pipe Q, and the piston and ram T fall. When the hand-lever is moved over into the other position, steam is supplied to the upper end of the cylinder H, and the slide A is moved down until the tool is in contact with the work, after which the lever L moves about the point M, and the valve of the cylinder R is depressed, to admit steam below the piston S. When the valve is moved downwards, the spring X closes the valve E. The ram T rises into the cylinder D, and forces the water into the cylinder A, to effect the forging or other operation. Fig. 3 shows a shearing-machine, in which the cylinder R is dispensed with. The lever L actuates a valve E, which controls the supply to the cylinder A from the high-pressure main at E<1> and a reservoir G.

Title: Improvements in and relating to Alternating-current Motors
Filed: 1904-02-16
Granted: 1904-12-22
Abstract: 3884. British Thomson-Houston Co., [General Electric Co.]. Feb. 16. Motors, controlling. -Repulsion motors are reversed and controlled, and a better power factor obtained, by a modification of the field windings and the use of a suitableswitch. Fig. 1 shows the rotor winding B, the commutator C, and the brushes b, b. The only parts of tberotorwinding in which secondary currents are induced by the transformer action of the coils A, A are the parts outside the lines 2-2 and 3-3 ; the parts between the lines 2-2 and 3-3 impede this induced current, and so lower the power factor, but, when the motor is at work, a current is generated in the parts between the lines 2-2 and 3-3, which opposes self-induction, and hence self-induction may be quite balanced by putting on an auxiliary winding D, D energized either by a separate current or by placing it in series with the coils A, A or the brushes b, b. To reverse the motor, the brushes may be shifted and the connections of the coil D, D reversed, but, where many motors are to be controlled, the device shown in Fig. 2 is preferred. Two out of the three windings A, D, and E are divided each into three parts d<1>, d, d<1> and e<1>, e, e<1>, and the connection to the controller are arranged so that in one position the coils A, A, D, D, and e, e are in series as indicated, and the coils e', e<1> are open-circuited, while in the other position the coils A, A, E, E, and d, d are in series, and the coils d<1>, d' are open-circuited. The motor may thus be started or reversed by putting the controller over to the contacts F or R as the case may be.

Title: Improvements in and relating to Electro-magnetic Mechanism, particularly for use in Railway Signal Apparatus.
Filed: 1904-07-20
Granted: 1905-06-29
Abstract: 16,110. British Thomson-Houston Co., [General Electric Co.]. July 20. Semaphore &c. signals; controlling and locking signals; automatic systems.- Relates to electromagnets or solenoids for the actuation of railway signals or for other purposes. Devices are adopted for automatically reducing the working current to a smaller holding' value after the movement of the signal &c. has been effected. Fig. 1 shows a solenoid for railway signal purposes, and Fig. 3 shows its relation to the track relay H in an automatic block system. The core B of the solenoid A has a slot connection with the lever C, pivoted at c<1>. The lever C is connected with the semaphore &c. signal in such a manner that, when the core is attracted, the semaphore is lowered from the normal 'danger' position to 'safety.' The outer member of a dash-pot D is carried by the lever C, and from it extends a lug d adapted to engage washers e on a sliding shaft E. A spring f<1> exercises a friction control on this shaft, which bears a bridging-member F adapted to short-circuit a resistance J, Fig. 3, when in its lowest position. When a train is in the section, the track-relay H is de-energized, the circuit through the solenoid A from the source of current I to the track R is broken at the armature h, and the switch F is in its lowest position, short-circuiting the resistance J. When the train leaves the section, the track relay is energized and the circuit of the solenoid A is closed. The core B is attracted, and the signal lowered to 'safety.' When this has been done, the switch F is lifted and the current reduced by the insertion of the resistance J in the circuit. This causes the core B and lever C to drop back slightly, until a catch on the dog G engages with a pin, thereby holding the signal at 'safety.' The reduced holding' current is strong enough to support the core B. When a train again enters the section, the 'holding' current is arrested, and the slotted core B drops sufficiently to trip the tail g<3> of the dog G and release the lever C, the signal then returning to the 'danger' position by gravity.
