Title: Improved Combined Spring and Frictional Resistance.
Inventor: CLOUD JOHN WILLS
Filed: 1903-04-22
Granted: 1904-03-03
Abstract: 9127. Cloud, J. W. April 22. Buffers; draw-gear.-A buffer is so arranged that the maximum load which can be applied may be increased by introducing frictional resistances controlled by the lateral swelling of the india-rubber or other resilient material. As the india-rubber rings 1. are compressed, they press against the segmental pieces 6, 7 and cause them to slide in the buffer, owing to the projections 8. Either the outer friction pieces 6, or the inner friction pieces 7, may be omitted. When the friction pieces 7 are omitted, the central piece 4 becomes unnecessary, and the pieces of india-rabber may be made in the form of solid discs. The arrangement may be used as a stationary buffer or as a draw-spring for vehicles.

Title: Improvements in and relating to Electric Switches
Filed: 1904-05-18
Granted: 1905-05-18
Abstract: 11,448. British Thomson - Houston Co., [General Electric Co.]. May 18. Motors, controlling.-Polyphase induction motors are controlled by a main switch which opens and closes the primary circuit and reverses the motor, and is actuated for the first two operations by the same handle as the resistance-controlling switch for the secondary circuit. The main switch B, Fig. 1, is enclosed in a casing A<1>, adapted to contain oil. The movable contacts B', B<2>, B<3>, Fig. 4, bridge across the fixed contacts c<1> .... c<8>, Figs. 1 and 4, which are connected as shown to the mains 1, 2, 3 and the primary terminals 1<1>, 2<1>, 3<1> of the motor. The contacts c<2>, c<4> and c<5>, c<7> are joined together. The movable member of the switch slides freely up or down the shaft b, but is prevented from rotating on it by means of the key K. It has a flange b<3> which is engaged by the forked end of a lever E pivoted at e. The weight of the forked end is partly balanced by a tension spring S. The other end of the lever E lies in a cam-slot H on the shaft of the controlling-switch D, which is of the ordinary drum type, operated by the handle D'. The first movement of the handle closes the main switch, completing the connections of the motor circuit, Fig. 4, from the line 1 through the contacts C<1>, B', C<3> to the terminal 1<1>, and so on. The handle also actuates the resistance controller, Fig. 4, in the first position 1<1> of which resistance is in circuit only between two slip-rings ; in the second position the third slip-ring comes into use, and in succeeding positions resistance is cut out step by step till the motor is shortcircuited. For reversing, a separate handle b<1> is provided, connected by a link b<2> to an arm fixed on the shaft b. On turning this handle from one position to the next, the bridging-contacts B', B<2>, B<3> are moved through a right -angle from the position of Fig. 4, interchanging the connections between the terminals 1<1>, 2<1> when the main switch is closed.

Title: Improvements relating to Electric Telegraphy.
Inventor: MUIRHEAD ALEXANDER
Filed: 1904-05-20
Granted: 1905-08-19
Abstract: 11,668. Muirhead, A. May 20. Telegraphs.-Relates to means for compensating for changes of zero in cable relays or receiving- instruments, such as are described in Specification No. 11,828, A.D. 1903. The compensation is effected by means of an auxiliary current of variable strength which flows either through the signal coil itself or through a second winding associated with it. In the arrangement shown in Fig. 1, the tongue f of the relay 8 moves over the vibrating contact-plate g, and any substantial change of zero causes it to make contact with the wire j or k. The electromagnet r or s is thus energized, and the permanent-magnet motor 3 set in motion in one direction or the other so as to vary the point of contact of the wire 13 with the rheostat wire 5. The current through the compensating-coil 11, 12 is consequently varied, and the zero adjusted. A potentiometer device may be employed as shown in Fig. 2, the direction of the current in the coil 11, 12 depending on the position of the contact-point x. The compensation may be effected by the use of a less sensitive relay in series with the main relay, the motor being set in motion when the second relay is sufficiently energized. The compensating - potential derived from the potentiometer may be applied between the cable and the artificial line.

Title: Improvements in Alternating Current Electric Motors
Inventor: BRADSHAW WILLIAM MAPLE
Filed: 1906-01-19
Granted: 1906-10-04
Abstract: 1481. Bradshaw, W. M. Feb. 1, 1905, [date applied for under Patents Act, 1901]. Energy meters.-The field-magnet system of an alternating-current motor, particularly designed for use as an energy or power meter, consists of two separate laminated core sections 2, 3, Fig. 5, one of which is provided with an inductive winding 16 having a large number of turns and arranged in shunt with the mains, while the other carries a non-inductive series winding 22 so that the fluxes due to the two field magnets may be in quadrature. The core section 2 has an extended polar projection 8 and two other projections 9, 10 which give rise to air gaps 14, 15, opposite which are located the polar projections 20, 21 of the core section 3. The core sections 2, 3 are clamped between a bracket 4 and lugs 5 on a supporting-base 6, as shown in Fig. 1. A conducting-disk 26, mounted upon a shaft 23, rotates between the field magnets, the number of rotations being registered upon a dial 27 by means of a train of gears 29. The speed of rotation of the disk is governed by one or more permanent magnets 30 adjustably secured by slotted brackets 31 to the bracket 4. To maintain the two magnetic fields in quadrature when the power-factor of the distributing-circuit is unity, a loop 34, Fig. 3, surrounds the projection 8 and is supported so as to be adjustable longitudinally by means of arms 35 having slots 36 for the reception of set-screws which secure it to the bracket 4. To overcome the friction between the relatively movable parts of the apparatus, a closed-circuit conductor 38, Fig. 4, pivoted at 40, is located with one side 39 in the air gap 14, adjustment being effected by means of the free end 41. The conductor 38 produces a different degree of magnetization in the air gap 14 to that in the air gap 15, and the difference between the field strengths is so adjusted that the speed of the disk will be increased sufficiently to compensate for the retardation due to friction.
