No. 16987.—17th September, 1903.—BARKER NORTH, A.R.C.Sc. London, F.C.S., of “Glenholme,” Glenholme Road, Manningham, Bradford, York, England, Lecturer in Chemistry. Improvements in and connected with electricity-meters.

Claims.—(1.) The improvement in electrolytic electricity-meters which consists in substituting for the electrolyte of an acid character a solution of an alkali or salt such as described, preferably caustic soda, and replacing platinum electrodes by electrodes formed of a substance which will remain “passive” in such an electrolyte—for example, iron, nickel, or cobalt, preferably iron containing less than 0·4 per cent. of carbon, such as wrought iron—for the purposes stated. (2.) Electrodes for electricity-meters of the kind described, consisting of iron, nickel, or cobalt, in a perforated, gridlike, or coiled form, substantially as described. (3.) For retaining the electrodes of electrolytic electricity-meters a given distance apart, the combined clip and spacing-piece G, g, substantially as described. (4.) In electrolytic electricity-meters, the application of a float in a vertical guide tube to move with the fall of level of the electrolyte for the purpose of enabling the fall of level (consumption of current) to be more accurately read, said float bearing a mark directly or carried by a second tube or paper within the float for reading on a scale, substantially as described. (5.) In electrolytic electricity-meters, the float-guiding tube having double walls forming an annular space closed at the bottom to receive and protect the scale, substantially as described. (6.) In electrolytic electricity-meters, the adjustable mounting of the float-guiding tube within the vessel by friction or a clip, substantially as described. (7.) In electrolytic electricity-meters, the application of dial mechanism for registering the consumption of current, said mechanism having an actuated drum operated by a cord or chain connected to a float which moves with fall of level of the electrolyte against the action of a suitable counterpoise weight, substantially as described. (8.) In electrolytic electricity-meters, the connection of the float to the actuating-drum of the dial registering mechanism by means of a cord of cotton or other cellulose material, which is rendered possible by the use of an electrolyte of a non-acid character consisting of a solution of an alkali or salt such as described, preferably caustic soda. (9.) In electrolytic electricity-meters, providing the measuring-vessel with one or more subsidiary vessels (or chambers) each containing an electrolyte and electrodes with or without intercommunication of all the vessels for maintaining a common level of electrolyte, and connecting all electrodes in parallel, whereby the subsidiary vessel or vessels act as a shunt, and only a known fraction of the current is passed through the measuring-vessel, thereby also enabling the capacity of the meter to be varied, substantially as described. (10.) The combined arrangement of electricity-meter and prepayment mechanism, comprising a main switch having a catch device to hold it open and an electro-magnetic device in a shunt circuit, including a prepayment index and a registering index, all so disposed that an inserted coin, which enables the prepayment index to be moved ahead of the registering index, liberates the catch, causing the switch to close for supply until the registering index overtakes the prepayment index and closes the shunt circuit through the electro-magnetic device, which now opens the switch and the catch again engages, substantially as described. (11.) The combination of electrolytic electricity-meter, prepayment mechanism, and means for registering the consumption on dials by the fall of level of electrolyte, substantially as described. (12.) The several improved constructions of electricity-meters—viz., the meter with float for accurate reading; the meter with dial registering mechanism; the meter with variable shunt for measuring a known fraction of the current; and the meter with prepayment mechanism—each comprising the several parts having the combined construction and arrangement adapted to operate substantially as described with reference to and shown in the respective figures of the drawings.

No. 17041.—30th September, 1903.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of the British Westinghouse Electric and Manufacturing Company, Limited, of Westinghouse Building, Norfolk Street, Strand, Westminster, England, Manufacturers, the assignees of Frank Conrad, of 1301, Walnut Street, Edgewood Park, Pennsylvania, United States of America). Improvements in alternating current watt-meters.

Claims.—(1.) An alternating-current watt-meter provided with two quadrature adjusting coils connected together in parallel circuit, and means for transferring resistance from the circuit of either of said coils to that of the other. (2.) An alternating-current watt-meter provided with quad-
rature adjusting coils connected in parallel with either one or two non-adjustable resistances and a variable resistance substantially as and for the purpose specified.
(Specification, 4s.; drawing, 1s.)

No. 17109.—16th October, 1903.—JOHN OGILVY MCPHERSON, of Fortrose, Southland, New Zealand, Farmer. An improved fencing-dropper.*

Claims.—(1.) An improved fencing-dropper consisting of the parts arranged, combined, and operating substantially as specified and illustrated. (2.) A fencing-dropper having a recess to receive fencing-wire, a plate pivoted upon said strip adapted to pass over said recess and maintain the wire therein, and a socket slidable upon the strip adapted to receive the plate and hold it in position, substantially as specified. (3.) A fencing-dropper comprising, in combination, a hoop-iron strip having a hook at its outer end to receive the top wire of a fence and recesses to receive the lower wires, plates pivoted upon the strip, one for each wire, adapted to retain the wires in the recesses, and sockets sliding upon the strip designed to pass over the plates and hold them in position, substantially as specified.
(Specification, 1s. 9d.; drawing, 1s.)

No. 17169.—27th October, 1903.—JOHN RAMAGE, of Balclutha, New Zealand, Tinsmith and Plumber. Improvements in taps.

Claims.—(1.) The combination and arrangement of parts constituting my improvements in taps, constructed and operating substantially as described. (2.) Improvements in taps, which consist in making the handle and spindle of the closing-valve and the valve-box at an acute angle with the general direction of the outlet, substantially as and for the purposes set forth.
