No. 26431.—17th August, 1909.—HARRY FISHER, of 30 Revans Street, Wellington, New Zealand, Carpenter. An improved life-saving apparatus.*

Extract from Specification.—The invention comprises a hollow cylindrical shell of sheet metal or the like which is brought to a point at each end so as to provide an approximately cigar-shaped shell. The conical ends of the shell are separated from the cylindrical portion thereof by means of bulkheads or partitions so that, if necessary, airtight compartments may be provided at each end to give additional buoyancy to the craft when afloat. Mounted longitudinally within the shell between the bulkheads is a passenger car or cradle, so disposed with regard to the shell or cylinder that the latter will be free to rotate around it. The cradle is mounted by suspending it from the centres of the bulkheads by means of hollow pivots or trunnions so that the hollow cores of the pivots may be used as communicating-passages between the cradle and the shell irrespective of any position the shell or cradle may assume with respect to each other.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 10s.)

No. 26583.—13th September, 1909.—JOHN BATE, of Parnell, Auckland, New Zealand, Engineer. An improved machine for washing and brushing flax or other fibrous matters.

Extract from Specification.—Providing a pair of endless chains or belts which run side by side and are driven by suitable wheels or pulleys. These chains or belts have battens of wood, iron, or the like joining the one chain or belt to the other, and the battens have suitable clips of thin steel or other metal attached to them for holding the hanks of flax or other fibrous matter to be treated; the path of the endless chains or belts with the battens attached thereto lead through fixed and revolving brushes and combs. The revolving brushes have a barrel built of wood or the like for the purpose of pressing the flax or like material against them. All of the above parts are mounted on a frame which serves as a washing-tank; and which has battens across it for the flax or like material to trail over.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 4s. 3d.)

No. 26697.—8th October, 1909.—JAMES CARTWRIGHT, of Granville Street, Vancouver, British Columbia. Means for enabling a blasting charge to be fired by a squib and detonator.*

Extract from Specification.—Lengthening the detonator so as to carry its open end in which the needle rod is inserted to a sufficient distance from the detonating end or from the cartridge to render firm tamping sufficiently safe. The provision of a flange on the detonator adjacent to the end which is inserted in the cartridge so that it will shoulder against the same and support its attachment thereto.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 7s. 6d.)

No. 26714.—12th October, 1908.—HUGH CECIL ROBINSON, of 35 St. James Place, London, England, Gentleman. Improvements in slide-rests.

[NOTE.—This is an application under the International and Inter-colonial Arrangements, the date given being the official date of the application in Great Britain.]

Claims.—(1.) A slide-rest for a turning-lathe wherein the tool-slide is moved by two harmonic-motion mechanisms simultaneously operating thereon. (2.) A slide-rest whereby the tool-slide is moved along a curved path resulting from the combination of the motions derived from two separate harmonic-motion mechanisms operated by a single handle, driving spindle-pinion, or the like. (3.) A slide-rest, as claimed in the preceding claiming clauses, wherein the length of the reciprocatory path of each of the harmonic motions communicated to the tool-slide can be independently varied.

[NOTE.—Here follow four other claims.]
(Specification, 7s. 6d.)

No. 26979.—2nd December, 1909.—ALFRED JOHN COTTON, of Queensland Club, Brisbane, Queensland, Australia, Pastoralist. Means for utilising the engines of motor-cars for imparting power for useful purposes.*

Extract from Specification.—According to the invention the usual main or driving shaft is provided with an extra gear adapted to operate an additional or counter-shaft for power purposes foreign to the car as such. The latter shaft may be arranged to drive through chain or other gearing a winding drum or winch mounted on the car, and thus utilise the engines for haulage or other purposes, in which case suitable anchor ropes or devices may be provided. Further, a pulley may be conveniently and removably attached preferably to the counter-shaft, around which pulley a drive-belt or the like may be suitably arranged for driving purposes.

(Specification, 3s. 6d.)

No. 27054.—18th December, 1909.—JOHN MITCHELL, of Queen Street, Auckland, New Zealand, Architect. Improved plug for walls of concrete, plaster, and the like.*

Extract from Specification.—An approximately parallel hole is bored in the wall, in some cases by means of an augur. In this hole is inserted a wooden plug having a longitudinal wedge-shaped portion cut away, the part removed approximately corresponding in shape with a metal wedge, and which is driven into the space between the plug and the periphery of the hole, thereby firmly securing the plug in position. The metal wedge is made with a corrugating or corrugations upon its surface to insure a tighter grip upon the plug. In making the wedges a plurality of them may be cast end to end in a long strip so that one after the other may be broken off as desired.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 2s. 6d.)

No. 27087.—21st December, 1909.—JAMES WILLIAMS, of 47 Crawford Street, Dunedin, New Zealand, and of 3 Lloyd’s Avenue, London, England, Mining and Mechanical Engineer. Improvements in the arrangement and construction of appliances employed in lixiviation processes for the extraction of metals.

Claims.—(1.) In a lixiviation plant for dissolving out metals from ores or metallurgical products, the combination of a percolating-vat with a self-regulating vacuum-pan for reducing the bulk of the dilute solutions obtained during the working-operations, and with a steam-oven containing a removable tray for evaporating down the enriched solution as described. (2.) Plants and appliances, substantially as described.

(Specification, 7s. 6d.)

No. 27111.—4th January, 1910.—JOSEPH PATRICK CARMINE, of Westport, New Zealand, Clerk. An improved tea-infuser.*

Extract from Specification.—According hereto the infuser is made of wire gauze, perforated tinplate, or the like having a hinged bottom retainable by a catch. The top is provided with a wire ring through which an adjustable wire handle is passed, and by which the handle is held fairly tight. The handle is kept in position and adjusted by a wire projecting from the side of the infuser and having a loop through which one side of the wire handle is passed.

(Specification, 3s. 3d.)

No. 27167.—13th January, 1910.—GEORGE LECESTER BURTON, of Christchurch, New Zealand, Acetylene Expert. Improved acetylene generator.

Claims.—(1.) In a device of the class described, the construction of the generator proper comprising an outer vessel having a portion of its upper surface enclosed, and a partition extending downwardly within the vessel for a desired distance from the edge of the cover, thus forming an enclosed chamber; a carbide-holder removably suspended within said chamber; and means for conducting the gas from said chamber, substantially as and for the purpose set forth. (2.) The improved acetylene generator constructed, combined, and arranged substantially as described and explained, and as illustrated in the drawings.
