Patent Office,

Wellington, 15th November, 1911.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office.

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. 28385.—20th October, 1909.†—JOHN DOWNHAM, of Barnbrook Iron Works, Bury, Lancaster, England, Engineer. Improvements in decorticating machinery for the extraction of fibres from the leaves of fibre-bearing plants.

Claims.—(1.) In a decorticating-machine of the type indicated, the arrangement, use, and application of the special shoe with a raised diagonal stripping-surface upon which the leaf is stripped by the blades of a rotating stripping-drum, substantially as set forth. (2.) The combination of parts arranged and operating substantially in the manner and for the purposes described with reference to the drawings.

(Specification, 4s. 3d.)

No. 28694.—7th November, 1910.—JAMES CHARLES PARKE KIRKWOOD, of 88 Willis Street, Wellington, New Zealand, Engineer. Automatic means or method of controlling or regulating the temperature of electrical heating and cooking apparatus.*

Extract from Specification.—Although means by which this object is carried into effect may vary considerably in detail and construction, the principle thereof will remain substantially the same, which is that of utilizing the expansive and contractive properties due to heating and cooling of suitable metals or materials to effect the automatic breaking and making of an electrical circuit which contains the heating-element. The expanding or contracting metal being either a part of the heating apparatus or a special part attached thereto, the expansion and contraction of said metal being caused by the increase and decrease of the temperature of the apparatus itself.

(Specification, 7s.)

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 28752.—18th November, 1910.—WILLIAM EDWARD HUNTER, of Maungakaramea, Whangarei, New Zealand, Farmer. An improved wire-strainer.*

Extract from Specification.—This invention relates to that class of appliance for straining fencing-wire in which a drum is mounted to rotate in bearings, and is provided with a ratchet-wheel adapted to be engaged by a pawl on a lever, and thereby to be rotated with the drum in order to coil the wire end on the drum and strain it to the required amount. The invention has been designed in order to provide a construction of bearing-frame for the drum by means of which the appliance may be readily suspended on a fencing-post, and removed therefrom after the wire has been strained and secured, and also to provide means whereby the usual detent-pawl for preventing any reverse movement of the drum, when straining, may be held out of contact therewith in order to permit of the wire being uncoiled from the drum when required. The invention is also adapted for use in straining and joining together the ends of two wires, and, when used for this purpose, is employed in conjunction with means whereby the strainer appliance may be suspended upon the wires.

(Specification, 5s. 6d.)

No. 28798.—26th November, 1910.—ALFRED LAUNCELOT JAMES TAIT, of 20 Anderson’s Bay Road, Dunedin, New Zealand, Inventor. Improvements in wire-grip fastener for clothes or suitable goods on lines, &c.*

Claim.—(1.) In improvements in wire-grip fasteners for clothes or suitable goods on lines, &c., a wire link with loops, coils, as required, or part of link having a base composed of wire loop or loops made to receive a line and the end or ends of wire to pass over the line down to one side of clothes-line, terminating in a loop or coil pressing over line or side of line, while the link is made to go down to other side of line as illustrated on the drawing, thereby completing pressing on both sides of lines as in Figs. 1, 2, and 3.

(Specification, 2s. 3d.)

[NOTE.—Here follow two other claims.]

No. 28799.—26th November, 1910.—ALFRED LAUNCELOT JAMES TAIT, of 20 Anderson’s Bay Road, Dunedin, New Zealand, Inventor. A rotary engine.*

Claim.—(1.) In a rotary engine, reversible when required, a cavity forming piston-wheel C having a shaft at E, and two ends of drum with flanges on each side of wheel C, combined with piston-rings in grooves of said flanges for bearing against rim N of cylinder-case A, and combined with cylinder-case A and with cavities C3 and with block-bars C1, and with free blocks and with caps and with sealing-bars combined in bar C1, and with buffer-spring and with rod C5, and cover C4, and with means to maintain a suitable pressure of bar C1 against rim of drum of piston-wheel C and sides of flanges marked D, and with ports H2 and H3, and with transmission-pipes, and with check-valves R3, R4, and P3, and R, the latter check inward supply, and with controlling-valves P and R, and with entrance-ports P3 and K, and exhaust and ignition-supply valves operated by cams engaging end of valve-rods, buffered by spring resting against the brackets SS, and with carburettors, and with means of ignition and compression by exhaust, and means for supplying benzine to the benzine type of engine, as described and explained, and illustrated on the drawing.

(Specification, 6s. 6d.)

[NOTE.—Here follows one other claim.]

No. 28810.—1st December, 1910.—JOHN HOUSE, of the Forestry Department, Public Offices, Spring Street, Melbourne, Victoria, Australia, Joiner. Improvements relating to the seasoning of timber.*

(2.) In improvements relating to the seasoning of timber, a chamber, manholes and air-inlets to said chamber, removable louvres to each manhole and air-inlet, a drop-door and downward deflector within said chamber and covering each manhole and air-inlet, a grating at the bottom of each drop-door and deflector.

No. 28823.—5th December, 1910.—CHARLES WILLIAM MARTIN, of Wellington, New Zealand, Plumber and Electrician. Improved means for the electric heating of ovens and other appliances.

Extract from Specification.—The invention consists principally in the combination with the appliance to be heated of a chamber in which the lamps are mounted, and which chamber is so constructed that the heat given off by the lamps therein may be concentrated and led into or through the appliance to be heated. This chamber is also so constructed that provision is made whereby the sockets of the lamps are kept cooled so that they shall not be damaged or affected by the heat of the chamber. The invention also embodies the employment of wire insulated in a particular and special manner for conveying the current to the lamps, such wires being specially insulated to protect them from the heat given off from the heating-chamber.
