Patent GB-189706428-A (GB)
Title: Improvements in Electrical Switches and Cut-outs.
Inventor: GOVER HENRY CHARLES
Filed: 1897-03-11
Granted: 1897-05-22
Abstract: 6428. Gover, H. C., Proctor, C. F., and Bate, A. H. March 11. Switches; cut-outs.-Relates to electromagnetic switches which may act automatically or may be operated from a distance. Figs. 1 and 3 show the arrangement. The contact arm or fork A is adapted, when in the on position, to complete the circuit between the contacts C and D, and it is held in this position by the end e of the weighted arm E catching under a roller F carried by the armature F of the electromagnet W. This armature normally is away from the magnet. The magnet coils may be in series with the circuit through a link H, or it may be energized from a distance. When the current through the magnet is sufficient, the armature F is pulled into the position shown, and lifts the roller F, allowing the rod E to fall. This pulls the arm A out from the contacts, the movement being assisted by the end k acting against the roller K. The forked arms of A normally tend to spring together, but are forced apart to make good contact by a nut a'.

Title: Improved Ground Anchor for Guiding Steam Scoops and the like.
Inventor: BROWN JOHN EDWARD
Filed: 1897-03-30
Granted: 1898-04-30
Abstract: 8119. Brown, J. E. March 30. Excavating.-Relates to an anchor and pulley for guiding steam scoops. A pair of tines or flukes C are pivoted on a cross-bar B, and are locked when in use by pawls D engaging with shoulders b of the forked frame A. When the pawls are raised, the tines can be readily drawn out of the ground and turned into the position shown in dotted lines. The implement can then be drawn over the ground like a sledge. A snatchblock or pulley E is mounted underneath a bar F which is pivoted to the frame A and passes through a slot in the lever G, also pivoted to the frame. On pushing the lever G clear of the bar, the pull of the rope or chain on the pulley causes it and the bar to turn upwards, thus freeing the rope or chain from the pulley.

Title: Improvements in Toy Pistols and Game Apparatus connected therewith.
Inventor: BAILEY HARRY DORNING
Filed: 1897-04-24
Granted: 1898-04-09
Abstract: 10,251. Bailey, H. D., and Budgett, H. B. April 24. Games played with skittles and pistols. - Relates to a game in which projectiles are discharged by a pistol to kn ock down skittles or to hit a target, the pistol being, if desired, operated by a coin-freed mechanism. The pistol A, B is mounted upon a ball-and-socket joint F', L' above a money box F, which is carried upon a suitable standard. The skittles are mounted on a board fixed over the inclined base J of an enclosed casing, and are all connected to a lever which is operated through a cord H<9> by an external knob Q<1>, whereby all the skittles may be raised into position by pulling the knob. The balls used as projectiles roll back to a curved fence J<2> leading to a shoot I which returns each ball to one of the receptacles or chambers Y<3> in a circular rotating drum P' forming part of the pistol. The projectile is discharged by the hammer, having a spring pawl D<3> engaging with a ratchet D<2> on a spindle D', and a notch D<7> to be engaged by the spring trigger C. Each time the hammer is brought to the cock, the spindle D<1> is rotated, and, by means of the bevel gear 0, P<2>, the drum is also rotated a certain amount-in the example shown one quarter of a revolution. The coin-freed mechanism, which may be varied, or omitted altogether, consists of a slit E leading to a space between two plates E', thence to a coin shoot, and through an opening E<3> to the box F. On the spindle D' is a star-wheel N (in this case with four arms), having a roller N' at the end of each, and a wheel M having a single slot therein. There are two spring sliding rods M<2>, N<2> having connections N<3> and M<5> leading to the space E. The effect of the coin falling down the space E is to make connection between the projecting ends of N<3> and M<5>, so that when the former is pressed inwards, by half cocking the trigger and thereby slightly rotating the spindle D' and starwheel N, the latter is forced outwards, and the end of the sliding rod M<2> withdrawn from the notch-wheel M, thus releasing the wheel M and allowing four projectiles to be discharged. When the rod M' falls again into the notch of the wheel M and the plate N<3> is in its most outward position, the coin falls, and no further rotation of the spindle is possible till another coin has been inserted.

Granted: 1898-03-26
Abstract: 11,148. Belfield, R., [Lamme, B. G.]. May 4. Motors, alternating-current; armatures; field magnets; controlling.-Relates to non-synchronous induction motors, in which alternating currents differing in phase are supplied to the primary member or field magnet, while the secondary member or armature is provided with a closedcircuit winding. Fig. 1 shows an end view of the motor, which comprises an outer fixed secondary element or armature 102 and an inner rotating primary member or field magnet 110. The former consists of a ring-shaped core, slotted to receive numerous alternately-arranged long and short conductor bars 103 and 104. These bars are connected together by conductors 105, as shown in Fig. 2, so as to form a continuous closed-circuit winding. Starting-resistances 106 are connected to the ends of the long conductor bars 103, by means of a ring 108, carrying contact-brushes 109 and provided with a handle 110 ; these are cut out when the motor attains its full speed. The primary member or field magnet 110 is provided with two separate windings, one of which is shown developed in Fig. 3 ; the other is similar, but is given the necessary angular displacement. In the example shown, each winding is composed of four groups A, B, C, D, each containing twelve coils connected in series. The groups may be connected either in series or in parallel, and the terminals are led to contact-rings. In a modification, the armature bars are all of the same length, and are connected together by end rings, one or both of which has a high resistance. Where there . are a very large number of armature bars, the short-circuiting brushes are arranged in zig-zag fashion, and the bars are slotted in such a manner that the brushes are able to clear them in breaking contact.

Granted: 1898-02-05
Abstract: 30,264. British Thomson-Houston Co. and Hobart, H. M. Dec. 22. Dynamos and motors, alternating- current; armatures. -In polyphase machines, having combined mesh windings 1, 2, 3 and star windings 4, 5, 6, such as are described in Specification No. 13,503, A.D. 1891, and d illustrated for three - phase cur - rents in the central diagram in Fig. 2, . the star and mesh windings are arranged alternately as non-overlapping coils, and their number is incommensurate with the number of poles. The winding is thus simple, and owing to the non- coincidence of the armature coils aud field poles, the inductance of the armature is reduced and dead-points are avoided. The mesh and star conductors differ in thickness and number of turns, as required by their connections, and to render the reaction of all the coils the same. ]<J:\ch coil may consist of two parts in different slots. For threephase currents, six armature coils are preferably used with either five or seven field-poles. Fig. 2 shows twelve armature coils with ten poles, only half the connections being shown. The coils are numbered to correspond with the central diagram. Quarter-phase windings are preferably arranged with four coils for three or five poles. The coils may be separately connected to switching-gear by which they can be connected as described, or the mesh conductors can be internally star-connected, or either set of conductors can be connected as a simple mesh or star, for starting.
