Title: Improvements in Systems of Electrical Distribution.
Inventor: THOMAS PERCY HOLBROOK
Filed: 1904-09-02
Granted: 1904-11-10
Abstract: 18,991. Thomas, P. H. Sept. 4, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Motors, controlling. - Relates to means for accelerating gradually the speed of directcurrent motors driven from an alternating-current source, or for raisingor lowering gradually the potential of any similar electric circuit. A switch is used to connect one after the other stepped leads of the secondary c o i l of a transformer through a vapour rectifier to a working circuit connected to one end of the secondary coil. As shown in Fig. 1, a directcurrent motor 14 is connected between one end of the secondary coil 2 of a transformer 1 fed with alternating current and the negative electrode 16 of a rectifier 17 having two main positive electrodes 18, 19 and two starting-electrodes 27, 28. The electrodes 27, 28 are connected to the ends of the secondary coil 26 of a transformer, the primary coil 28 of which is connected across the ends of the coil 2. The neutral point of the coil 26 is connected through a choking-coil 30 to the negative electrode 16. The electrodes 18, 19 are connected respectively to the movable contacts 21, 23 of a suitable switch, the fixed contacts 8, 9, 10, 11, 12 of which are connected by stepped leads to the coil 2. The contacts 21, 23 are such that, when starting the motor, the contact 26 engages a fixed contact before the contact 23 leaves it, and the contact 23 engages the next contact before the contact 21 leaves the last one. Assuming the contacts 12, 23 only to be engaged, current flows from the transformer via the electrodes 19, 16 to the motor. When the contact 21 also engages the contact 12, the electrodes 18, 19 share the current. When the contact 23 leaves the contact 12, the electrode 18 takes all the current. When the contact 23 engages the next contact 11, the electrode 19 feeds current of high potential to the motor, the flow of current from the contact 23 to the contact 21 being prevented by the rectifier. The steps are similar at eash contact. When lowering the potential, it is necessary for a suitable device to be added to break the circuit each time the contact 23 leaves a fixed contact. In cases such as electrically-propelled vehicles in which slow stopping is unnecessary, it is better to provide a circuit breaker. In a modification, Fig. 2, both phases of the alternating current are utilized. The motor is connected to the neutral point of the coil 2. Three main positive electrodes 31, 32, 33 are provided, connected respectively to movable contacts 34, 35, 36 adapted to engage successively with fixed contacts connected as shown to the stepped leads of the coil 2. The operation is similar to that of the arrangement shown in Fig. 1, opposite sides of the transformer being stepped up alternately. The switch may, however, be arranged to step up both sides simultaneously.

Abstract: 24,931. Venner, R. F. S., and Griesbach, R. C. Dec. 1. Switches.-Two adjustable arms, oparated by clock-work, close a switch and open it after a predetermined time. A graduated disk A revolves once in twenty-four hours. Two arms B, B' are mounted loosely on the axle on opposite sides of the wheel A, and secured by clamping-disks or enlarged bosses. A bell-crank lever D is pivoted at E and carries a pin D<1> which engages with the arm B. The short arm of the lever D is held by a spring F to make contact with the spring G, and a second contact in series with the first is made when the lever D depresses the spring H to touch the spring H'. A pivoted lever I, controlled by a spring K, has a shoulder P to hold the lever H down, and a peg I' placed in the path of the arm B<1>. To set the switch, the arm B is coupled to the disk A in the desired position, by a friction or clamping disk which screws down over the arm, and the arm B<1> is similarly coupled to the disk, the angle between the arms corresponding to the time during which the circuit is to remain closed. The arm B, revolving with the disk, strikes the pin D<1> and causes the bell-crank lever D to depress the spring H, which is then held in contact with the spring H<1> by the shoulder I<2> on the lever I. The arm B passes and releases the lever D, which is lifted by the spring F to touch the arm G. The circuit is then closed through the springs. H<1>, H, lever D, and arm G. When the arm B<1> reaches the peg I<1>, the arm I is moved to release the spring H and thus to open the circuit. The lever I is preferably provided with an adjustable tip as shown in Fig. 2. The arms and disks may be placed in front of the time-disk, or the latter may be stationary, while the arms may be fixed to the axle after adjustment. One of the arms may be fixed to the time-disk and three or more arms may be used, one for closing the circuit of arc lamps, and one for breaking both circuits together. Two disks on different axles geared together may be used, and the switch may be used as a relay. According to the Provisional Specification, the arms may be secured to the time-disk by a pin or spring pawl engaging a series of holes or teeth on the disk.

Abstract: 1819. Lock, W. H., Holbourns, J. G., and Longhurst, H. A. Jan. 24. Linotype machines. - In means for justifying tabular matter, the various measures forming the line are separately justified in the assembler between two adjustable abutments, one of which may be the yielding resistant which is pushed back by the matrices as they are assembled. The front bar of the assembler is provided with a scale consisting of a rack 8, Fig. 1, the notches in which register with a row of holes 11 in the rear bar. Abutments 12, Fig. 3, are adapted to be placed across the assembler, their lower edges engaging the notches of the rack 8, and pins 13 on their rear ends entering the holes 11. One abutment is placed in the assembler at a distance from the entrance end equal to the length of the first justified measure of the line, and the matrices composing the measure are assembled. A second abutment 12 is placed across the assembler at the right-hand end and the measure is justified by means of quads inserted by hand. The left-hand abutment is then moved to the left through a distance equal to the length of the second measure, which is then assembled and justified in the same way, and so on until the line is completed. The abutments may be secured to the assembler and be retractable from the path of the matrices, in which case a separate abutment is provided for each notch in the rack 8. The lower edges 16, Fig. 9, of the abutments are dovetailed and slide in dovetailed grooves, and stops 17 are provided to limit the retraction of the abutments, which may be effected by means of hand-levers. In a modification, a vertically-sliding right-hand abutment is used. Expanding spacers may be used to justify one measure of a line, provided that the corresponding measure in the succeeding lines is justified in the same way. When the yielding resistant is used as the left-hand abutment, the matrices forming. the line are assembled, and the resistant is pushed to its extreme left-hand position. An abutment 12 is then inserted at the right-hand end of the first measure and the measure is justified. The abutment is then withdrawn and inserted at the right-hand end of the second measure which is also justified, and so on. The last measure of the line is justified by means of expanding spacers.
