Patent GB-190303687-A (GB)
Title: Improvements in Jacquard Machines.
Filed: 1903-02-17
Granted: 1904-02-17
Abstract: 3687. Textile Appliances, Ltd., and Carver, T. A. B. Feb. 17. Jacquards.-A twilling-jacquard is constructed to form a twill of one kind in the figure of the cloth, and a twill of another kind in the ground. In order to twill the figure, gaps are provided in the lifting-knives a, as shown in Fig. 1. These gaps are of suitable number and disposition to produce the desired twill, and the knives are moved longitudinally at each turn of the loom, so that the gaps take up new positions to cause the hooks to be left down in the proper sequence to produce the twill. If the hooks to be left down occur all in one row, ordinary twilling-bars may be used. To twill the ground, certain hooks are raised in the proper sequence, by forming second hooks in the vertical wires, as shown in Fig. 1<a>. These additional hooks are engaged by suitably-arranged projections on a lifting-bar, which also slides longitudinally at each turn of the loom to engage the hooks in their proper sequence. The projections r may be formed on the backs of the next knives a, as shown. The form of the projection r is such that it will lift its hook when the knife a is in either its normal position, as shown at A, or in the position into which it is rocked by the ordinary twilling-bars, if these are used to produce the figure twill, as shown at B. The hooks and knives are so arranged that, when any hook is in the position to be engaged by the ordinary knife, its additional hook is out of the path of the corresponding projection from the next knife, as shown at C. If convenient, the lifting-bars of the additional hooks to produce the ground twill may be rocked bytwilling-bars. The invention is described as applied to an ordinary machine of 24 rows of 50 hooks for producing an eight-leaf twill in the figure of the cloth, and a five-leaf twill in the ground. As there are 24 rows in the machine, the eight-leaf twill in the figure may be produced by the use of twilling-bars. The knives a, Fig. 4, are carried in holes c in the brander frame, which has vertical motion in vertical guides in the ordinary manner. The holes c are shaped to allow the knives to rock through the range required by the eight-leaf twilling- mechanism, and to be moved longitudinally by a horizontal rod d supported at its ends by levers e fixed to a spindle f. The lever e carries a roller h working in the groove of a cam j, which is rotated a fifth of a revolution at every turn of the loom by ratchet mechanism, and is shaped to move the lever e, rod d, and knives a into five successive positions to produce the proper five-leaf twill. By bevel gearing l, giving a ratio of 5 : 8, a shaft is rotated to operate the mechanism for rocking the knives to produce the eight-leaf twill, or this shaft may be driven by any arrangement ordinarily employed for driving the twilling-shaft and the cam j driven from it.

Title: Improvements in or relating to the Rolls or Rollers of Paper Making Machines and the like.
Inventor: BERTRAM DAVID NOBLE
Filed: 1903-02-19
Granted: 1904-01-14
Abstract: 3917. Bertram, D. N., and Milne, S. Feb. 19. Paper machines. - The leading rolls of papermaking machines are driven frictionally at a slightlygreater surface speed than the travel of the web through the machine, and rotate, with a small amount of slip, at the normal speed of the taut web. Any slack occurring in the web reduces the slip, and is taken up by the consequent increased speed of the rolls. The friction drive may also be applied to the breast, wire, and felt rolls. Each end of the roller c, Fig. 1, is fitted with a bush a<1>, which is secured by set-screws b to bosses a<2> fitting on the roller shaft d. The friction due to the weight of the roller effects the drive. A belt pulley f drives the shaft d, which is supported in bearings e at each end, and is thickened up within the roller to give the required strength. Collars g may be fixed on the shaft close up to the bosses a' to increase the frictional drive, or a spring h, Fig. 4, bearing against adjusting-nuts j or a fixed roller on the shaft, and pressing a washer i against the boss a<2>, may be applied at one or both ends of the roller. In a modification an ordinary roller, provided with gudgeons at the ends, or fixed to a shaft, is mounted in an ordinary bearing at one end and fits in a long sleeve at the other end, the long sleeve being supported in bearings and driven by a rope pulley. Each gudgeon or end of the spindle may fit in a driven sleeve. In some cases, the sleeve is formed at the end of a driven spindle. A device similar to that shown in Fig. 4 may be applied to the end of the sleeve to increase the friction. The frictional drive may be effected by friction discs.

Granted: 1906-09-20
Abstract: 19,210. British Thomson-Houston Co., and Wedmore, E. B. Sept. 22. Cut-outs; distributing; switches.-In an alternating-current distribution system with generators in parallel, an electro-magnetic device cuts out a faulty generator on a reversal of energy occurring. The primaries B, B<1>, B<2>, B' of series transformers are connected between the generators A, A', A<2>, A<3> and the bus-bars 1, 2. The secondaries C, C<1>, C<2>, C<3> of each transformer are connected to earth by the buswire D, and also to circuit-breaker trip coils E, F, &c., or these may be relay coils used in connection with the trip coils of the circuit-breaker G. The junctions between the two coils E, F of the several feeders are connected by a bus-wire K, thus connecting the coils F, F', F<2>, F<3> in parallel, so that they take a current proportional to the output of the machines taken together. 'The coils E take currents proportional to the current of each separate generator. On a reversal occurring, the current in the coil E is reversed, causing the relay to operate, and the circuit-breaker G is opened. A switch L may be provided to connect the junctions of the relay coils to the bus-wire K. The coils F between the bus-wires H, K may be aided by windings M connected with a resistance or reactance N across the main bus-bars 1, 2, or to a potential transformer. The relay used is preferably of the watt-meter type, and has two coils, one fixed and one moving, which are at right-angles when the currents are in the same direction, the fixed coil being preferably the output coil. On reversal, the coil moves an arm P away from a stop to complete the circuit of the tripping-coil Q across direct-current mains 3, 4. The coils may be normally at an angle less than 90‹, and a stop used to limit the movement on reversal so that the two coils stand at right-angles. The fixed or output coil may be replaced by two coils in series, their inductive effects being opposite and approximately equal. The device is particularly for use with single-phase alternators, or in one phase of three-phase alternators in which the mid points are not grounded.

Title: Improvements in Tachometers.
Inventor: BUTLER ARTHUR CECIL
Filed: 1906-04-10
Granted: 1907-01-24
Abstract: 8634. Butler, A. C. April 10. Speed indicators. -A screwed shaft e, Fig. 3, driven from the vehicle carries a nut l which is in frictional engagement wit h a plate j driven through a friction pad h<1>, a plate h, and a shaft g by bevel-gearing e<1>, g<1>. Connected to the dial b is a block b<2>, in which slides a rack k reciprocated by the nut l and actuating a nointer c. The velocity of the diskj is kept constant from the time the minimum speed which the apparatus registers has been attained, any increase of speed from this causing the nut to move along the screw and actuate the pointer. The controlling- mechanism for keeping the speed of the disk j uniform is as follows :-A shaft o is carried by a plate n', on which is mounted a sleeve o', bearing a pinion o<2> driven by the plate through gearwheels m, m<1>, m<2>, m<3>, Fig. 4. Loosely mounted on the plate n', about the sleeve o', is a cylindrical box p in which moves a plate q carrying studs q<1>, Fig. 2. Pivoted to each stud g<1> is a brake member q<2>, and mounted on the sleeve o<1> is a cross-piece r, each arm of which is pressed into engagement with a brake member by leaf springs q<3>. The box is closed by a tight-fitting cap p<1> on which presses a spring s mounted on a standard s', the tension being adjusted by a bell-crank s<1> and screw s<3>. Below the minimum speed the power applied by the cross-piece on the ends of the pieces q<2> is not sufficient to overcome the pressure of the leaf springs, and the plate q is revolved through the pins q<1>, but, as the speed increases, the members q<2> are forced against the sides of the box, which is pressed upon the plate n<1> by the spring s and slipping occurs, thus retarding the plate j and causing the nut l to advance. In a modification, shown in Fig. 5, the regulating-means consists of a weighted wheel t driven from the pinion d by gearing m<1>, t<1>. Connected to the wheel t by a crank v is a disk t<4>, to which is secured one end of a coiled spring t<5>, the other end being fastened to a weighted balance wheel u loosely secured on the same shaft. The balance-wheel is caused to oscillate to a greater extent when the velocity is above the minimum than when it is below, and thus results in a reaction through the spring t<5> on the plate j and causes slipping to occur between it and the pad h<1>.
