Patent GB-190224712-A (GB)
Title: Improvements in Alternating Current Electric Motors, also applicable to Meters of the Induction Type.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1902-11-11
Granted: 1903-10-01
Abstract: 24,712. Carolan, E. A., [General Electric Co.]. Nov. 11. Motors, controlling. - Relates to means employed for the production of a rotary field in induction motors &c., the object being to enable the speed of the rotary parts to be adjusted by means of a variable auxiliary field in inductive relation to the rotating member. In the case of an induction motor, the main series winding e<1> is in series with a non-inductive resistance r across the mains 1 and 2, and an auxiliary winding g<1> is shunted across a portion of the resistance r. The core h<1> of the winding g' projects into the space between the main core f<1> and the squirrelcage armature a<1>, and carries two secondaries m<1>, n' on its ends. The speed is adjusted by varying the shunted fraction of the resistance r. The resistance r may be connected across the mains independently of the winding e<1>, and the various parts may be modified to suit a multipolar machine. The series and auxiliary coils may be solenoids, and the secondaries may be omitted or made adjustable in order that any desired phase displacement between the two windings may be obtained. The use of the auxiliary field coil is stated to be of general application to devices employing multiphase currents.

Title: Improvements in Electrical Instruments for Signalling on Railways.
Inventor: TYER EDWARD
Filed: 1902-11-17
Granted: 1903-10-22
Abstract: 25,240. Tyer, E., Hollins, F. T., and Leake, F. W. Nov. 17. Signalling-instruments; crossing-gate signals.- Electrical instruments worked by momentary currents, especially by one line wire with earth return, of the kind described in Specification No. 9284, A.D. 1901, and adapted for level-crossing signalling, are shown in Figs. 1 and 3. The indicators 25, 26, Fig. 1, are operated respectively from the up and down stations, and the coils of the relays 1, 2 are introduced into the line wire at the gate cabin. The relay armatures operate contacts which are arranged so that an indicator will respond to a current from its proper station and will be shortcircuited by a current from the other station, the signalling-current being at the same time transmitted to the next station, and a local circuit including the bell 30 closed. When the armature 3 is lifted and the contacts 14, 15, 16 connected, the indicator 26 and coil 2 are short-circuited by the wires 28, 29. Further movement of the armature causes the extension piece 7 to raise the spring 9 and insulating-piece 27, so breaking the earth connection and closing the local circuit operating the bell by the spring 10. Instead of the spring 10, a separate relay may be included in the line wire. The indicators 25, 26 may be provided with midway detents as described in Specification No. 9284, A.D. 1901, and these may be released by currents transmitted from a local battery, or by terminal batteries, or they may be worked by reduced battery power operating a releasing-current derived frum a local circuit. In the last-mentioned arrangement, an electromagnet having an armature with an extension is employed. The armature is held by a spring against a stop, and the extension co-operates with a pivoted lever working between two contacts and normally held against one by a spring. The springs are so proportioned that a weak current in the electromagnet causes contact between the armature extension and the pivoted lever without raising the lever, while an increased current causes the armature to carry over the lever to the other contact. The apparatus shown in Fig. 3 is adapted to be operated by the working of the tablet instrument at either end of its section, and comprises the electromagnets 51, 52, the indicator needles 53, 54, and the roller 72 for locking either the indicator 53 or the indicator 54. When a current is sent from the up station, indicating that a tablet is out, the needle 53 moves until the angle-piece 69 on the flat spring 67 comes in contact with the pin 61. On the current ceasing, the projection 74 on the flat needle-piece 63 contacts with the pin 61 and the indicator is held midway. On the current being repeated, the indicator moves right over.

Granted: 1903-06-18
Abstract: 5377. Jackson, A. C. March 7. Cameras; change-boxes.-A method of changing plates or films in hand cameras after exposure, and simultaneously indicating the number remaining is described. Fig. 4 is a vertical section through the camera at right-angles to the plateholders L<2>, L<3>, and Figs. 6 ... 9 show successive phases of the action of the plate-changing key or detent C. Fig. 2 shows an under view of the plate A at the top of the camera. The front plate L<1> is held in the exposure position by the rotary key or detent when in the position shown in Fig. 6. On turning the key C, one of its wings enters a slot in the plate, and the continuance of the turning motion detaches the front plate from the remainder and allows it to fall forward. The key C and plate E, Fig. 2, can be rotated together by the lever D within limits defined by the projections F, F<1> and stops G, but unless so rotated they are kept in the exposure position shown by the spring J. When the key C is thus moved, the spring pawl S engages with a ratchetwheel N, and alters the number displayed by the latter externally.

Title: Improvements in or relating to Heel-pricking and like Machines.
Inventor: BOULT ALFRED JULIUS
Filed: 1903-11-13
Granted: 1904-11-10
Abstract: 24,743. Boult, A. J., [United Shoe Machinery Co.]. Nov. 13. Punching and perforating m a - chines for leather &c.-Relates to a machine for punching holes in articles preparatory to nailing them to their supports, being described in the Specification as a heel-pricking machine. The heel i s automatically fed into a position in front of a stripper plate 70, Fig. 3, where it is engaged by a heel-seat die 38 removably fitted into a presser-plate 34 which is adjustably secured to a sliding carriage 20. The latter is reciprocated by a crank and gearing from the main driving-shaft of the machine, and, as it moves towards the left, the plate 70 recedes with it and the heel is forced on to a number of awls 58 which project through holes in the plate 70 from a block 56 carried by an upstanding arm 54 of a bracket 50 which is bolted to the machine frame. The plate 70 is suspended by an adjustable stem 80 between guide-posts 68 of a stripper frame which is supported by rods 66. During the movement of the carriage to the left, the extended stems of the rods 66 move in guides bored in the arms 54 against the resistance offered by split sleeves 92 clamped to the stems, these sleeves ensuring that the plate 70 will remain in any position into which it is moved. In the reverse movement of the carriage 20, adjustable screw stops 96 abut against the ends of the stems and force the plates 70 to the right, so that the heel is stripped off the awls. In order that the heels may be conveniently and quickly fed into position, a number of them are arranged in alignment in a guideway which moves with the guide-posts 68, and are successively fed forward by a pivoted lever 111 which oscillates with the carriage 20. The operator inserts another heel into the entrance of the guideway upon the return movement of the lever, thereby obviating any likelihood of his hands being caught in the machine, a fender 108 acting as a further safeguard for this purpose. As each heel is fed forward, it is engaged by the forked end of the stem 120, Fig. 5, of a positioning-device which is preferably yieldingly mounted in its supporting- yoke 124 so that it may automatically accommodate itself to slight variations in the size of different heels. The yoke 124 is supported upon the ends of arms secured to a rock-shaft 138, which is actuated by the engagement of a roller, on an arm 140 depending from the shaft, with a sliding cam 144 yieldingly connected to the carriage 20. By this means, the positioning-device is automatically rereciprocated vertically to engage, centre, and hold a heel while is being pricked, and then to release it so that it can be pushed out of the way by the next heel.
