Patent GB-190428471-A (GB)
Title: Combined Starting and Braking Device for Electric Motors.
Inventor: HULTQVIST ARTHUR
Filed: 1904-12-27
Granted: 1905-03-30
Abstract: 28,471. Hultqvist, A. Dec. 27. Motors, controlling.-Relates to the combination with a starting-device of means whereby the connections of the motor are changed so that the machine acts as a generator when the starting- switch is automatically returned to its 'off' position. The switch arm 1, Figs. 1 and 2, carrying a contact-plate 2 adapted to bridge the contact-plate 3 and the resistance contacts 4, 5, 6, &c., is provided with a hook-shaped projection 26, which engages with a pawl 25 when the switch arm is in the operative position. The pawl 25, which is secured to the armature of an electromagnet 261, releases the catch 26 when the safety circuit containing the electromagnet is made or broken, the switch arm being returned to its ' off ' position by a spring 24, Fig. 2. The switch arm when in its end positions operates insulated bars 17, 18 by engaging with shoulders thereon. Supported by the bars 17, 18 are two contact-pieces 15, 16 adapted to bridge the contacts 13, 14 and the end resistance contacts. When the switch arm is in its operative position, the connections being as shown in Fig. 3, the current flows through the wire 27, contact 13, contact-plate 2, contact-plate 3, wire 30, and shunt motor 29. When the switch arm is released and moves to the right, the motor 29 is disconnected from the positive terminal of the source of current, with the consequent reversal of the direction of the current in the inductor. The direction of the current in the shunt 31 is, however, unchanged, so that the machine acts as a generator. The resistances 12-9 are successively cut out, and, when the switch arm reaches its zero position, Fig. 4, the contact-pieces 15, 16 are moved to the right. To start the motor again, the switch arm is moved to the left, the resistances 9-12 thereby successively disconnected, and the contact-pieces 15, 16 moved into their left positions. In Fig. 5, the switch arm is rotatable through almost a whole revolution, and a single contact-piece 32 may take the place of the pieces 15, 16. In the case of a series motor, in which it is necessary, when changing the machine from motor to generator, to maintain the current in the same direction in the field, a change-over switch 33, Fig. 6, is operated by the switch arm when it reaches either of its end positions. In the application of the invention to asynchronous motors, a change-over switch 42, Fig. 7, in the primary circuit and switches 43, 44, 45 in the secondary circuit are adapted to be operated by the switch arm.

Detonator apparatus; miniature signals or indicators.-A slide feed detonator apparatus is described, and is provided with a trip releasing-device in the wire connexion to the signalman's hand-lever, allowing the apparatus to return to its normal position after operation, without the corresponding return of the hand-lever. The detonators b, Fig. 1, are contained in a vertical tube magazine, the pile resting on a plate c supported by two cords passing over pulleys to two weights outside the magazine A sliding-bar ejector i pushes the top detonator on to the rail l, when sectors m, m<3> are released from the cabin, being rotated by a weighted lever m<1>. An upper sliding-bar displacer k is provided to displace the detonator from the rail under the action of a spring k<6>, when a tappet k<5> is released from engagement with a catch n on a pivoted weighted lever n' by a projection n<2> on the sector m engaging a projection on the lever n'. The displacer k is returned simultaneously with the forward motion of the ejector i by a connexion from a projection on the displacer k to a sector k<3> attached to the sector m. A pivoted flap k<1> on the displacer k is pressed upon the pile of detonators by a spring k<2> to retain them in position. The wire o<2> leading from the drum p<1>, which rotates the sector m, is connected to a slide s, Fig. 4, which carries a pivoted catch s<1> resting upon a pivoted block r<1>, which is carried by another slide r provided with a wire o' leading to the hand-lever o and with another wire o<3> leading to a counterweight. The hand-lever o is moved in the direction of the arrow to actuate the apparatus, withdrawing the slide r and the slide s through the catch s<1>, until the block r<1> passes off a fixed table t and rotates, thus freeing the catch s' and allowing the slide s to return to its normal position. An electric bell, indicating to the signalman the presence of a detonator on the rail, is in circuit with a spring contact u<1>, Fig. 1, carried by a vertical slide u and with a fixed contact on the side of the magazine. These contacts are closed by the tail of the detonator on the rail depressing the slide u, the ejector i being slotted to avoid depressing this slide during its movements. The bell circuit also passes through contacts v, w<1>, Fig. 4, on the handlever and its frame, so; that by slightly moving the lever from its normal position the signalman may ascertain whether or not a detonator is on the rail.
