Patent GB-190517930-A (GB)
Title: Improvements in and relating to Alternating Current Electric Motors
Inventor: MARTINETTO VICTOR
Filed: 1905-09-05
Granted: 1906-02-15
Abstract: 17,930. Martinetto, V. Sept. 5. Motors, alternating-current; armutures ; field magnets.-In an alternating-current motor, the field winding acts inductively upon a second winding, the current from which is led into a third or torque-producing winding, mechanically coupled to the second winding, the field due to the third winding reacting with the main field to produce a driving-torque. Either the field or the mechanically - coupled windings may rotate, and the mechanically-coupled windings are so related that, when the current in the second winding is at its maximum, the field axis of the third winding is inclined to the main field axis. As shown iu Fig. 1, the field winding is divided into two portions 3, 4 connected in series, the two halves of each portion being in multiple, so that the field axes are in the lines 12, 13. The current-producing winding 5, having its slotted core mounted on the shaft 10 by non-magnetic spokes 11, is connected by a conductor 6 to the torque-producing winding 7 provided with a laminated core 8, which may be slotted to reduce self-induction. The fields due to the windings 5, 7 are therefore at right-angles. In Fig. 6, the windings 5, 7 are mounted in non- inductive relation upon a common cone structure, and are acted upon by a common field winding 2, supplied by a three-phase source, a rheostat 14 being inserted in the secondary circuits for the purpose of regulating the speed. The flux due to the winding 7 also compensates for the lag in the armature current. To render the machine selfstarting, the number of poles in the main field should differ from the number of pules produced by induction, as is the case in Fig. 6. For this purpose, in the single-phase motor shown in Fig. 4, the core 8 is divided into three branches separated by 120 degrees.
Patent GB-190518611-A (GB)
Title: Improvements in or connected with Time Registers
Inventor: BERESFORD WALTER
Filed: 1905-09-15
Granted: 1906-08-23
Abstract: 18,611. Beresford, W. Sept. 15. Time-checking apparatus; driving-mechanism for record-strips.-In an autograph time recorder, a record strip is exposed for signature by raising a hinged flap 1, Fig. 3. This causes the strip to be perforated with a dial indication of the time, while lowering the flap advances the strip, if desired, by a uniform amount. Additional "in" or "out" perforators may also be provided. When the hinged flap is raised, the last signature with its time record is visible through a glass plate. The perforating-device is shown in plan in Fig. 4, and comprises hour and minutes perforating- needles 16, 16A which may be distinctive and are carried by plates geared to a toothed barrel 12 of the clock train. Twelve needles 22 on a fixed ring and a needle on the central spindle perforate a dial, or instead, dials may be printed beforehand on the record strip 4. The whole perforating- device is carried by a frame supported on a slidable spindle 24, as shown in sectional view in Fig. 3, and can be advanced against a spring 27 to perforate, by an arm 31 on a rocking shaft. A second arm 30 on this shaft is engaged by a piece 29 projecting from the hinged flap 1, thus causing a perforation to be made when the flap is raised. Spring-controlled "in" and "out" perforators 43 are carried by the hinged flap, and an inking-pad may be provided for the perforating-needles. The piece 29 on the hinged flap 1 also engages an arm 34 of a bell-crank which advances a record delivery roll 6 by rocking a pawl-carrying lever 38 pivoted on the roller spindle against a spring. If a regular feed of paper is required, a rod is hinged to the end of the pawl-lever 38 and rests on the paper-roll. The free end of this rod passes below a fixed bar, so that the pawl-lever can only rock until the rod is held by contact with the paper and the fixed bar, the amount of rocking decreasing as the paper roll becomes thicker. The supply roller is provided with a braking-spring 48 to keep the paper stretched, and the recording- mechanism except the clock-work and time-marking portions is mounted on a removable plate 49. A bell may be rung at each actuation.

Patent GB-190602726-A (GB)
Title: Improvements in and relating to Lifting and Locking, or Sliding and Locking Gears applicable to Sluice Gates, Shutters and the like
Inventor: ANDERSON HARRY PERCIVAL HARVEY
Filed: 1906-02-05
Granted: 1907-01-24
Abstract: 2726. Anderson, H. P. H. Feb. 5. Sluice gates.-Relates (1) to means for operating sluice gates, heavy shutters, or other sliding closures for apertures, of the type in which there is no contact between the jointing - surfaces during the sliding of the shutter &c., white the latter is forced into close contact with the frame when driven home by the continuation of the closing- movement, thus making a water-tight joint, and (2) to the use of an outer shutter with a sliding window or closure operated in the above manner. The shutter 9, Fig. 1, is closed by means of bevelgearing 7, 6, screw gearing 3, 5, and worms 2 operating racks mounted on bars 10 attached to the shutter by parallel-motion links 11. The bars 10 slide in channels in the frame so that they are not free to move in a direction at right-angles to their length, while the shutter slides on projections 12 until it is just closed. When the shutter has cleared these projections and its motion has ceased, the continuation of the closing movement forces the bars 10 farther homo and thus, through the parallel motion, drives the shutter upon its jointing-surfaces. The shutter &c. 13, Figs. 4 and 6, is closed in a similar manner, but in addition it is fitted with a door 16 sliding through a slot 17 in the same frame. This door is operated by bevelwheels 19 from gear 21, or, by means of the friction gear shown in Fig. 7, the shafts 4, 20 may be operated independently from the same driving- gear 24. A shank 35 on the bevel-wheel 25 passes through the two screw gears 26, 27 and carries a cone 30, which may be made to slide on a rod 31 and thus to mesh with either gear by adjustment of a nut 34 which screws into the shank 35 and on the rod 31.

The usual " nighting " pin at the top of the plug is replaced by a snug e projecting from the washer d and working in a groove f in the tap body. When the plug does not extend through the tap body, the spring and washer are fitted at the top of the plug.

Granted: 1908-01-16
Abstract: 1534. Ridley, J. M. Jan. 21. Protractors. - An instrument for determining the face and edge cuts of two meeting surfaces coinprises a graduated circular base A, within which is fitted an adjustable ring B. Graduated half-circles E, G are pivoted to the rings A, B respectively, and the half-circles may be set at any angle relatively to the base by means of graduated gauges 0, R pivoted at P, R'. A graduated dial L is secured to a block K sliding in a slot J cut in the half-circle E, and a spindle M carrying a pointer N works in the block K. The lower end of the spindle M is fixed to a shoe I working in a T-shaped groove H in the lower half-circle G. By adjusting the relative position of the base circles and the inclinations of the graduated half-circles to correspond to the angles at which the two pieces are to stand relatively to each other and to the horizontal, the face and edge cuts can be determined from the reading on the dial N and the graduations with which the half-circles register at their point of crossing.

Abstract: 18,797. Collier, A. T., and Reilloc Tyre Co. Aug.20. Rollers, covering.-The process described in Specification No. 4680, A.D. 1907, [Abridgment Class Wheels &c.], is applied to the manufacture of indiarubber-covered rollers. The rolleris built up of a number of layers of india-rubber increasing in elasticity from the iron shaft to the periphery, the harder layers being composed of a vulcanite mixture with varying proportions of the soft rubber forming the periphery. Another method of making the roller consists in forming each layer of the same rubber or rubbermixings, but with increasing amounts of sulphur in the layers from the periphery to the innermost layer, so that after vulcanizing, the layers increase in hardness from the periphery to the core. As shown in the Figure, the steel or other core a is surrounded by a layer b of hard vulcanite, and layers c, d, e of india-rubber gradually decreasing in hardness in the order named, and upon these layers is an outer layer f of soft rubber.
