Patent GB-190423834-A (GB)
Title: Improvements in or connected with Alternating Current Induction Motors.
Filed: 1904-11-03
Granted: 1904-12-15
Abstract: 23,834. Hunt, L. J., and Sandycroft Foundry Co. Nov. 3. Armatures. - The resistance of the short-circuiting ring or rings of the rotor of an alternating-current motor having cross - connected squirrel - cage windings, such as described in Specification No. 19,948, A.D. 1903, is increased by placing only one end of each cross-connection in direct electric contact with the short-circuiting ring at that end of the rotor. A further object of the invention is to facilitate the dissipation of the heat generated in the high-resistance shortcircuiting rings. The conductors B, which are displaced axially or are made in two sizes so that alternate bars project beyond the rest at one or both ends, are shortcircuited alternately at both ends of the rotor by low-resistance connections E, the required pitch of which is obtained by dividing the total number of conductor bars by the normal number of stator poles. For example, conductors 1, 10 are connected together at one end of the cage, and conductors 10, 19 at the opposite end, and so on. The remaining conductors are joined up in a similar manner, but adjacent connections are made in opposite directions, the two next connections being conductors 2, 10 and conductors 3, 12. The conductors B may be arranged in groups, alternate groups having their ends projecting beyond the others. The projecting ends of the conductors B at one or both sides of the rotor are connected together by rings C of a high- . resistance material, and the non-projecting ends may be independently short-circuited by a second high-resistance ring, from which the first-mentioned conductors are insulated by fitting them with insulating-sleeves. The high-resistance rings may be either solid or laminated, or they may consist of a coil or helix of wire wound on the extremities of the conductors B, which are grooved for the purpose, thereby facilitating the escape of heat. This method of producing the high-resistance connections is stated to be applicable to other types of rotor, and any other form of short-circuiting connection may be adopted.

Patent GB-190502320-A (GB)
Title: Improvements relating to Railway Fouling and Locking Bars and the like.
Inventor: RIECK LUDWIG
Filed: 1905-02-06
Granted: 1905-10-19
Abstract: 2320. Rieck, L. Feb. 6. Points and switches. - Relates to railway fouling and locking bars and the like, and consists in means for preventing damage to such a bar and its connexions by the passage of a vehicle over the same when the bar is in its raised position, and also in means for electrically interlocking such a bar with its operating-lever. Fig. 1 shows the invention applied to the locking-bar of facing- points which are adapted to be trailed through, a purpose for which it is especially applicable. The locking-bar 1 is mounted on links so as to avoid in all positions a direct thrust on the pivots of the links. The point-operating rod 5 is connected to the pivoted lever 6, which carries a pinion 7 gearing with the fixed quadrant 8. This pinion is connected, through the crank-pin 9 and link 10, with a sliding-block 11 connected in turn with the locking-bar by suitable links and the bell-crank lever 13. The parts are arranged in such a manner that it is impossible for the centres of the lever 6, pinion 7, pin 9, and block 11 to fall in one line, dead-centres being thus avoided. As the rod 5 operates the points, the locking-bar will, through the arrangement described, be caused to rise aud fall simultaneously. In the case of a fouling-bar, the rod 5 would be connected directly to a suitable operating-lever instead of to the point rod 16. To interlock the locking-bar electrically with its operating-lever, it is directly connected up so as to operate during its rising and return movement the switches 17, 18, which are arranged in circuit with the indication magnets 19, 20. The switches are alternately closed by the projections 23 on the disk 21 which is rotated by the locking-bar through the ratchet gearing shown. The remaining portion of the indication circuits and switches are stated to be well known, being shown in Specification No. 13,466, A.D. 1901.

Granted: 1905-09-21
Abstract: 10,749. Suzuki, T. May 23. Internally-flued boilers; settings.-The passage of the hot gases through the combustion chambers and smoke-tubes of a water-heater or a steam generator can be prevented by two dampers acting in unison, which cause the products to proceed directly to the chimney, thus permitting the inspection and cleaning of the boiler without drawing the fires. In Fig. 1 the combustion products as shown by the arrows pass through the flue 7 in the boiler 1 into the chamber 10, which is provided with oppositely-placed apertures 12, 13. Pivoted at 20 and 21 are the dampers 18, 19, which, by means of cranks 22, 23 and a link 24, can be moved simultaneously by the handle 25. In the position shown, the gases pass into the inspection chamber 9 and then through the smoketubes 8 to the trunk 11, whence they proceed to the uptake 6 by the opening 14. When the handle is thrown over to the left, the dampers take up the position shown in dotted lines, and the gases pass from the flue 7 through the opening 12 direct to the chimney. In the modified form represented in sectional elevation in Fig. 4, the internal flue is dispensed with and the products traverse the smoke-tubes 8 to the chamber 29, thence proceeding through the trunk 11 to the uptake 30. When the dampers 31, 32 are operated, the gases are caused to pass directly to the chimney through the opening at present covered by the damper 31.

Title: Improvements in Automatic Fire-arms
Inventor: FREEMAN CHARLES
Filed: 1905-07-29
Granted: 1906-01-25
Abstract: 15,601. Freeman, C. Aug. 15,1904, [date applied for under Patents Act, 1901]. Breech actions, sliding breechblock.-The breech-block of an automatic gun is driven a short distance to the rear by the explosion and is then stopped. This short movement imparts a sufficient velocity to a momentum-block, in contact with the breech-block, to enable the momentum-block to disengage the pivoted locking- dog of the breech-block and to retract the breech-block. The return movement is effected by a spring connected to the momentumblock. Fig. 1 shows the gun before the trigger has been pulled. Fig. 5 is a section of Fig. 1. Fig. 10 shows the momentum-block and Fig. 12 the breech-block and locking-dog. The locking- dog 23 is pivoted at the forward end of its shank 24 to the slotted lug 21 of the breech-block 10, the pivot-hole being elongated so as to permit the breech-block to be driven back into contact with the locking-dog 23, which is connected to the momentum-block by a pin 27 and an angular slot 12. As the momentum-block moves back, the locking-dog 23 is turned about the pivot in the lug 21 and thus drawn aside out of the recesses 35 in the breech frame. The pivoted hammer 40, Fig. 11, is held back after recocking, even when the trigger continues to be pressed, by an additional sear 44 which is slightly longer than the sear 45. The trigger carries an auxiliary pivoted finger 48 normally in contact with the toe 46 of the longer sear 44. On the trigger being pulled, the finger 48 lifts the sear 44 and the hammer falls slightly and is caught by the sear 45, which is lifted by the fixed finger 49 of the trigger. During the pulling of the trigger, the pivoted finger 48 is turned aside by engaging the incline 50 so that the longer sear 44 is released ready-to fall into bent when the hammer is cocked.

Title: Improvements in Apparatus for Controlling Electrically Propelled Trains.
Filed: 1905-10-17
Granted: 1906-10-11
Abstract: 21,068. Siemens Bros. & Co., and Lydall, F. Oct. 17. Motors, controlling. -In multiple-unit train propulsion with alternating- current motors, e.g. single-phase series motors, where control is wholly or partly effected by varying the impressed voltage, the line feeds a transformer having a divided secondary winding, switching- means,.and induction regulator combined so as to vary the ratio continually. Reference is made to Specifications No. 23,398, A.D. 1901, and No. 1874, A.D. 1905, [Abridgment Class Electricity, Regulating &c.], various improvements upon which are described. Figs. 1 and 2 show diagrammatically the variable-ratio transformer with induction regulator, and Fig. 3 the installation for one car without the driving-motors. The rotatable primary P of the induction regulatoris joined by slip-rings, in shunt with the transformer secondary winding A B. To economize space and equalize the turning-moment, two secondary windings S', S<2> at right-angles are placed on the stator of the regulator, and are connected at their middle points, preferably with an intervening choking-coil W as in Fig. 2, to one side Z of the motor circuit. Their ends are adapted to be connected in proper order to the various sections of the transformer secondary winding by a drum switch MB, Fig. 3. To shorten the drum switch, a double set of contact-fingers is used, and the segments are separate one from another. In the form shown in Fig. 2, the points of connexion are taken so as to make the turning-moment nearly independent of the position of the rotor. To furnish the required torque, a pilot motor, pneumatic cylinder, or other apparatus is used. In the installation of Fig. 3, the pilot motor M, geared to the rotor of the induction regulator IR, is of the single-phase series type, exerting a torque dependent on the electromotive force at its terminals, and is connected in an auxiliary circuit supplied by a small transformer E, with a switch F for varying the active portion of the secondary winding. The auxiliary circuit controls a main cut-out MS, and contains a reversing-switch D for the main motors and a master-controller mc from which run a number of wires to fingers s, t, u, v playing over auxiliary contacts on the main barrel MB, by which means current is led to one or other of the fingers q, r, thus effecting the reversing of the motor M through the special means shown in Fig. 4. These consist of oppositely-wound primary windings of a small transformer T, mutually in parallel and in use alternately, in series with the field of the motor M, and a common secondary connected with the motor armature. A magnetic clutch is arranged to hold the motor armature in the position at which it has arrived when the current is turned off, and to free it again when re-energized.
