Patent GB-190722832-A (GB)
Title: Improvements relating to Armatures for Electric Motors.
Inventor: LAMME BENJAMIN GARVER
Filed: 1907-10-16
Granted: 1908-03-05
Abstract: 22,832. Lamme, B. G. Nov. 3, 1906, [date applied for under Patents Act, 1901]. Armatures. - An alternating - current motor, adapted to be operated alternatively as a commutator motor with a given number of field poles and as an induction motor with fewer poles, has armature coils of a pitch intermediate of the respective polar pitches, conductors being provided which cross-connect equipotential points in the windings of the armature when the motor acts as a commutator motor, and serve to short-circuit the armature when the machine acts as an induction motor. The armature conductors are connected to the commutator segments through resistances, and the cross-connexions are arranged at the ends of the resistances remote from the commutator. In the example shown, the motor has eight poles 1, 2, 3 ... at starting and during low-speed running, and four poles 9, 10, 11, &c. for highspeed running. Assuming a sine current, the curve 14 represents the variations of field strength for the smaller number of poles, and the curve 15 for the larger number. The particular armature pitch which effects the best compromise between the best pitches for the four-pole and eight-pole fields is that represented by the distance between the points 20 and 21 where the two curves 14, 15 cross each other, and the pitch is nearer in value to the ideal pitch for the larger number of poles than to the pitch for the smaller number. The armature coils are connected to the commutator 22 by means of resistance conductors 23. Armature coils similarly situated are connected together by cross-connexions 25. The number of poles for starting and running may be other than eight and four respectively, and the numbers may bear any desired ratio to one another.

Granted: 1910-02-21
Abstract: 4135. Allen, R. Feb. 19. [Addition to 17,437/07.] Packing, metallic; packing, removable casings, containers, or carriers for.-Relates to the packing described in the parent Specification, in which segmental packing-rings are formed with wedge ends acted on by radial wedge blocks. In the form shown in Figs. 5 and 6, segmental or split rings a, a<1> are contracted by wedges c, in which the head c is formed separate from the shank b and is secured to it by a nut c<2>. The shank is formed with an extension for covering the joint. Where two or three rings are arranged in the same joint, they are formed with bevelled surfaces, and one ring acting as the wedging-ring may alone be acted on by contracting wedges, the other rings having wedges of the form shown at c<3> for covering the joints and preventing rotation. The packing-rings are arranged in grooves in rings d secured in an outer casing e by a screw ring f. The joint between the casing and the stuffing-box is made by a cup-leather or other packing h. In a box for a rotary shaft, rotation is prevented by a key between the rings d and the casing e and projections k on the casing entering recesses in the box. In the form shown in Fig. 7, the wedges are acted on by axial spring plungers n. The packing has spherical end joints d, d<1>. In a modified form of joint, the covering-flange of the wedge is formed in the middle, and enters slots in the packing-rings.

Title: Improvements in or relating to Systems for Lighting Railway Trains by Electricity.
IPC: H02J7/22
Filed: 1909-03-08
Granted: 1909-08-05
Abstract: 5544. Siemens Bros. Dynamo Works, Broadhead, F. G., and Wall, T. F. March 8. Electro-magnetic switches.-In a train-lighting system, the electro-magnetic means provided for preventing the recharging of the batteries is controlled by an extra contact or set of contacts upon the main lamp switch. A spring-controlled armature a<2>, Fig. 2, adapted to close contacts a, a' also carries a third contact, engaging with a contact a'. The coutact a<4> is in series with a pair of contacts a5 adapted to be closed by a voltage relay placed across the battery to be protected. A switch a<6>, placed on the main switchboard, is adapted to be closed when the lamp circuit is open, and to be opened when the lamp circuit is closed. When the switch a<6> is closed and the voltage relay bridges the contacts a<5>, the magnet a<3> is energized, thereby attracting its armature and open-circuiting the shunt field winding of the dynamo at the contacts a, and the solenoid of the main switch at the contacts a<1>. The lifting of the armature a' closes the circuit of the magnet a<3> through the contact a', thus keeping the magnet energized if the contacts a<5> should be opened. If, however, the voltage of the battery falls very low, the spring a<x> operates to close the contacts a, a'. If the lighting-circuit is closed while the magnet a<3> is energized, the armature a<2> falls, thereby closing the contacts a, a<1> of the dynamo. In the modification shown in Fig. 3, the magnet a<3> has a certain amount of residual magnetism, and the coils 1, 2 are oppositely wound, the former being in series with the contacts a<5> and the latter with the switch a<6>. When the contacts a<5> are bridged by the voltage relay, the winding 1 lifts the armature a<2> to cut out the dynamo. When the contacts a<5> are opened, the residual magnetism of the magnet a<3> is sufficient to hold the armature up until the switch a<6> on the lamp switch momentarily closes the circuit of the winding 2 which causes the armature a<2> to fall. Electrically-tripped switches.-In another modification, the armature a<2> :is held in its raised position by a catch, which releases the armature electromagnetically when the switch a<6> is momentarily closed.

Granted: 1910-06-20
Abstract: 6755. Link, R. P., and Morgan, A. C. March 20. [Cognate Application, 21,388/09.] Single-type composing and casting machines; keyboards; driving-mechanism.-In machines in which matrices are presented one at a time to a mould for casting separate types, and are distributed among two or more magazines in a rotary or other movable support, each of which can, at will, be brought to the operative position, the magazines are positioned by a frame which is successively raised, rotated, and lowered. Each magazine comprises four matrixbearing sectors 2 symmetrically arranged about a centre line in pairs in two different planes. Tubular extensions 3 on the sectors are detachably connected to operating-sleeves 5 by means of bayonet or like joints 4, and the sectors in each magazine are supported by sleeves 7 carried by flanges 9, which are bolted together and to a plate 10 having a rim 12 resting upon a frame 11. Three magazines are symmetrically arranged in the frame 11. Depression of a key 13 operates a linkage 14, 15, 16 to depress a detent 17 and so throw into action a clutch 18, 20, Fig. 10, whereby motion is transmitted to a shaft 22 from a shaft 21, and a cam 26 is thus rotated. A cam device 23, 24 throws the clutch out of action, and a pin on the member 18 limits the shaft rotation to one revolution. The cam 26 actuates a rack 27 and gears 29, 31, 32 so as to rotate a screw-threaded shaft 33 and thus raise a nut 34, which is prevented from rotating by ribs 36. Terminal teeth 37 on the nut come into engagement with teeth on the frame 11, which is thus lifted, and finally spring latches 39 at the upper ends of the ribs allow the nut and frame 11 to rotate through one-third of a revolution. Immediately afterwards, a spring 28 returns the rack 27 and the nut 34 to normal position, the nut being prevented from rotating backwardly by means of the latches 39 and ribs 36. In this way, a magazine is lifted from a cylinder 6, and is replaced by another magazine. By successive depressions of the key 13, the three magazines are brought into operative position in turn. The nut carries three cams 45 for actuating a slide 46, which operates levers 42, 43 to rotate the sectors for releasing the bayonet-joints 4 before the sectors are raised. The levers 42 are moved first, and, lugs 50 thereon coming into contact with lugs 51 on the levers 43, these levers also are moved, and the sectors are brought into the positions shown in Fig. 8. Forks 54 or rollers on the levers engage the edges of the sectors. Each pair of sectors in the same plane are linked together by springs which tend to lock the joints 4. A magazine may be withdrawn from the frame 11 by hand, and another substituted, by operating a pin 55 which slides in a slot 56 and carries a plate 57 adapted to move the levers 42, 43 and so unlock the joints 4. A bolt 58 on the plate 57 normally locks the plate 10 to the frame 11, but is moved out of action when the pin 55 is actuated.
