Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 26th January, 1910.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

The copies of claims and extracts from the specifications and drawings are merely intended to give some further indication of the invention than is disclosed in the title, and the complete specifications and drawings should be referred to for a description of the invention.

No. 25411.—6th January, 1909.—VERONA ROBERTINA BLAIR, of 24 Jessie Street, Wellington, New Zealand. Improved acetylene-gas generator.*

Extract from Specification.—Consists in the combination with the ordinary water-tank and gas-holder fitting therein of generating-chambers suspended within the gas-holder and communicating with the water-tank by pipes extending downwards, and each of which generating-chambers is provided with a casing having a closed top and open bottom fitting therein and adapted to receive the carbide. This casing is provided with a spring valve in its top end that is adapted to be opened by means of a screw-pin threaded through the top of the generating-chamber, and thereby to control the escape of air or gas from such casing, and thus to govern the level of the water in the generator and the consequent generation of the gas.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 5s. 6d.)

No. 25434.—12th January, 1909.—JOHN HUTCHINGS, of Capel House, 62 New Broad Street, London, England, Mining and Mechanical Engineer. Improvements in and relating to direct-acting pumping-engines.

Claims.—A direct double-acting pumping-engine, comprising a double system of pistons and cylinders mounted on a rod common to both pistons, and the movements of which are controlled by a double-acting plug-valve provided with cavities and passages, and a U-shaped divisional wall connecting the solid parts of the valve, the respective sections formed by this divisional wall forming controlling-channels for the driving and driven fluids so as to direct them simultaneously into their respective appropriate chambers and passages, and means for securing co-operation between the air-driven piston, piston-rod, the water-driving piston, and the connected parts co-acting therewith. (2.) A double-acting plug-valve having formed therein cavities and passages and a dividing U-shaped wall, connecting the solid parts of the plug, whose respective sections formed by this divisional wall constitute channels which respectively serve as controlling-channels for the driving and driven fluids so as simultaneously to direct the respective fluids into their appropriate chambers and passages. (3.) The direct double-acting two-cylinder pumping-engine, with double-acting control-valve and connections, all substantially as described and illustrated by the drawings.

(Specification, 5s.)

No. 25476.—21st January, 1909.—GEORGE LUCAN PEARSON, of Christchurch, New Zealand, Inventor. Improved well-boring appliance.*

Claims.—(1.) Improved well-boring apparatus, consisting of the parts constructed, arranged, combined, and operating substantially as specified, and illustrated in the drawings. (2.) In well-boring apparatus, the employment of a pivoted arm having pulleys at either end to guide the operating-rope, with means for oscillating the arm as specified. (3.) The arm referred to in claim 2, in combination with the disc and lever for operating the same, substantially as specified. (4.) In well-boring apparatus, the employment of a disc and lever pivoted thereon for operating a rope, a projecting pin or block adapted to catch the lever, and a slot in the lever which thereby is free to be drawn down the diameter of the disc and release itself from the pin or block, substantially as specified. (5.) In well-boring apparatus, the means for taking up slack in the driving-rope, consisting of the ratchet-and-pawl mechanism, substantially as set forth, and illustrated particularly in Fig. 11. (6.) In well-driving apparatus, the combination of parts whereby the boring-rods and tube-driving gear may be worked separately or together, substantially as described and illustrated. (7.) In well-boring apparatus, the combination and arrangement of parts comprising the means whereby as the pipes are driven by the monkey the monkey-rope is permitted to uncoil from its drum, thereby insuring an even tension upon the monkey-rope, substantially as specified, and illustrated particularly in Figs. 1 and 3. (8.) In well-boring apparatus, the combination with pipe-driving apparatus of a drum around which is coiled a wire rope led beneath a guide-pulley and connected to the top of the well-pipe, substantially as and for the purposes specified and illustrated.

(Specification, 7s.)

No. 25504.—28th January, 1909.—JOHN COUTTS, Electrical Mechanic, and ALFRED HENRY DAVIES, Mechanical Engineer, both of 4 Cargill Street, Dunedin, New Zealand. Improved electrical cable-connector for tapping-off and crossing lines.*

Extract from Specification.—According hereto, a bridge-piece threaded upon or suspended upon one of the cables is bifurcated to receive the other cable, and a clamping-piece sliding within the bifurcation is clamped upon the second cable by a nut screwing upon the bridgepiece, and bearing against wings projecting from the clamping-piece.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 2s.)

No. 25645.—4th March, 1909.—EBENEZER HALLEY DONALDSON, of Karamea, Nelson, New Zealand, Flax-miller. Improved apparatus for washing flax-fibre.*

Upon the travelling-belt are disposed a plurality of bifurcated hooks, upon which the hanks of fibre are suspended, and which draw the fibre through the pipe against a current of water delivered thereto under high pressure.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 2s.)

No. 25668.—8th March, 1909.—ROBERT GEORGE PALMER, of Blenheim, New Zealand, Settler. Improvement in the construction of life-saving rafts for use in case of shipwreck or otherwise.*

In a raft of the class described, a device for holding the airtight pontoons in position and allowing raft to be closed for stowage or extended for use by means of girders or cross-ties hinged to pontoons and jointed, the bolts of such joints sliding in the slots of a central keelson or batten in floor of raft, and automatically locking by means of spring catches in slots of keelson, substantially as specified, and shown in drawing. (2.) In a raft of the class described, a flexible floor or grating constructed of transverse ropes extended from inner sides of pontoons to keelson, and longitudinal battens or bamboo rods and rope netting secured to said ropes, substantially as specified and shown in drawing. (3.) In a raft of the class described, the attachment of a canvas shoot or fire-escape arrangement for transferring passengers from wreck to the raft, substantially as described.
