Patent GB-190306784-A (GB)
Title: Improvements in and relating to Voltage Regulators for use in Charging Storage Batteries.
Inventor: LEBLANC ALEXIS
Filed: 1903-03-24
Granted: 1904-03-10
Abstract: 6784. Le Blanc, A. March 24. Dynamos, regulating. - In charging batteries from a dynamo driven at a variable speed, as on automobiles, or on trains lighted electrically, the dynamo is regulated by means of a variable resistance in the field circuit, and, should the potential fall below a certain limit, the charging- circuit is automatically opened. In the construction shown, the apparatus consists of a block of rubber or the like A formed with two chambers partly filled with mercury, into one of which two carbon or like resistance rods d, e dip. Connected with the resistance chamber is a receptacle h covered with a flexible diaphragm k against which the core of the magnet m presses. Fig. 1 is a diagram of the circuits, in which t is the dynamo armature, u the field, s the battery, and I the induction coil of the igniter. In normal working, the magnet m, which is in a shunt circuit, forces in the diaphragm, causing the water with which the chamber is filled to force down the mercury in the resistance chamber, and lift it in the other chamber to complete the circuit for charging the battery at g. Changes in the potential vary the pressure on the diaphragm and thus raise or lower the mercury and short-circuit more or less of the rods d, e, so varying the resistance in the field. Should the potential fall below a certain limit, the contact is broken at g.

Abstract: 10,460. Cole, R., and Cole, r. May 8. L i f t valves.- Relates to taps for jars and watersupply pipes &c. The tap shown in Fig. 1 has a shank a with a large rounded thread for screwing into a jar m<2>. The shank is separate from the body b, and passes loosely through it. A washer k is interposed between a collar on the shank a and the body b, and a washer m is interposed between the body b and the boss m<1> on the jar m<2>. The shank a is provided with a passage n, and a cylindrical chamber g in which the valve f works. The valve f may be of indiarubber, and is carried by a spindle i passing loosely through a screw plug j, by turning which the valve is operated. When the valve is lifted from its seat, the liquid flows through orifices h in the shank a into the space c, and escapes by the nozzle d. The plug f fits the chamber g closely, in order to prevent leakage along the screw plug j. In a tap for a water-supply pipe &c., shown in Fig. 3, the body o is made in one piece with the shank as there is less risk of leakage. The valve g<1> moves in a chamber formed in a plug p, which screws into the valve body. When the valve is lifted from its seat q, the liquid escapes through a space left between the seating g and the end of the plug p.

Abstract: 10,498. Reeb, A. J. A. May 8. Filters of similar filtering-units. -Filters composed of juxtaposed similar and symmetrical sections, for working under pressure or exclusion of air, are constructed so that the liquid cannot come into contact with a metallic surface or remain in contact with caoutchouc, and the nature and thickness of the filtering-medium may be varied. Fig. 4 shows an arrangement of several superposed filtering units, while Fig. 3 shows a sectional view of one such unit. A hexagonal frame a, fitting on the adjacent frame by grooves with india-rubber or earth-flax packing, is provided with tubes n, o, at opposite angles, which connect all the chambers 1, 3, 5, &c., Fig. 4, to form one inlet chamber, and all the chambers 2, 4, 6, &c., to form an outlet chamber for the filtered liquid. The remaining four angles of the hexagonal frame a are provided with elliptical locking-pins m mounted eccentrically to hold down rings i, which fasten perforated plates h resting on a flange d inside the frame a, the filtering-medium being held between the two plates h. Three thicknesses of filtering-media may be employed by fixing the plates h first, as shown in Fig. 3, second, by fixing one plate h outside its ring i, the other plate h being fixed between the ring i and the flange d, and third, by fixing both plates h ontside the rings i. India-rubber rings i<1>, placed in grooves in the rings i, and the flange d, act as washers. The pins m are turned by a key fitting in square holes in their ends, and are fixed in position by small pins passing through the rim a into holes in the pins, or engaging in teeth on the pins. Fig. 9 shows a modified form, in which the rings i are made of double T-section for lightness, a bearing-ring u being also used between the plate h and the clamping nut s, whose screw r is held down by lugs v on the frame a holding a cross-piece on the screw r. An india-rubber ring inside the nut s protects the screw-thread from liquid. The tubes o, n, Fig. 4, connecting the units directly, may be closed, when successive filtration through each unit is required, and, if the apparatus is used horizontally, small orifices, provided with the usual small valves, are provided on the top of each section for the escape of air.

Title: Improvements in connection with Electrostatic Wattmeters or Watt-hour Meters.
Inventor: WILSON ERNEST
Filed: 1904-03-07
Granted: 1905-01-26
Abstract: 5582. Wilson, E. March 7. Armatures; commutators ; field magnets.-In order to apply to the quadrants of an electrometer a pressure proportional to the current in a supply main, the quadrants are connected to the brushes of a small continuous - current generator, the armature of which is driven at constant speed by any motor 66, and the field coils 60 of which carry the main current or a definite fraction of it. The armature 43 of the small generator may have two windings and commutators, connected in series, to give a neutral connection. If the frequency on the alternating-current main changes, the pressure from the small generator is kept proportional to. the main current by varying a shunt to the field coils, or by using an induction motor to drive the generator and varying the resistance in its induced circuit. The generator is made with as little metal as possible, and no iron, and with numerous sections in the armature and commutator. Fig. 13 shows a suitable form in sectional plan. Two rectangular field coils 60 are formed of copper strip, each with two windings connected so that two equal field windings are formed ; these are connected in parallel or series by four terminals 50, 55. With very large main currents, special field coils are not required, the armature being supported near the main itself. The armature wires are laid between pins on two ebonite discs 43, carried by a thin phosphor-bronze spindle 35, which is supported by bearings 36 on insulators ; the ends of the armature wires are connected to pins set through ebonite discs 44, the edges of which are grooved to receive the brushes upon the pins. The brushes are carried by wooden rockers on tubes 37.

Granted: 1904-07-28
Abstract: 7224. Jenkinson, W. R. March 25. Couplings, automatic.-A T-headed draw-hook is fitted to enter a slotted plate attached to the end of the next carriage, the plate being automatically turned round to lock the hook. The verticallyslotted plate i, Figs. 1 and 4, is carried on the ends of horizontal bars f, g supported on arms e by collars d which slide in grooves on the buffer casing b. The bar g is heavier than the bar f so as to tend to pull down the plate i until the slot m is horizontal. The motion of the plate i is limited to a right-angle by the inner ends of the barsf, g working in quadrantal slots in the base-plate c of the coupling. The plate i is held in position for coupling by a recess in the back of the plate engaging a pin l on the buffer head, and also by a catch F, Fig. 5, the stalk D of which passes through an eye E on the buffer casing, and is attached to the buffer head. The T-headed draw-hook q is carried on a spring- controlled draw-bar o and, on entering the slot of the opposing coupling-plate, drives back the buffer head, releasing the pin l from its recess and the catch F from the arm e, and thus allowing the plate to swing round to lock the coupling. The draw-bar and buffer rods are square to prevent rotation. The draw-bar may be fitted with rubber or other resilient washers in its casing to reduce the force of concussion. Uncoupling is effected from either side by levers, as shown in Fig. 4, which raise the heavy bar g from the lower to the higher position.
