No. 29153.—21st February, 1911.—LEVIN AND CO., LIMITED, of Customhouse Quay, Wellington, New Zealand, Merchants (the assignees of Alexander Gilbert Hutchinson, of care of the above company, Sheep-shearing Machine Expert). Improvements relating to sheep-shearing machines.

Extract from Specification.—According hereto, the usual tail-piece that screws into the tail of the shear-socket is provided with an internally screwed portion at or near its forward end, while the remainder of the inner periphery of said tail-piece is left smooth and parallel and preferably of slightly larger diameter than the screwed portion. The bush, instead of being threaded externally throughout its entire length as hitherto, has a thread provided upon its end corresponding to the length of the internal thread in the forward end of the tail-piece. The remainder of the external diameter of said bush is turned to correspond to the same diameter as the internal diameter of the inner plain portion (mentioned above) of the tail-piece. The length, however, of this plain parallel portion is comparatively large in respect to the length of the threaded portion thereon. A shoulder is provided upon the bush to bear accurately upon the end of the tail-piece.

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

No. 29222.—6th March, 1911.—HENRY McDONALD, of Putaruru, Auckland, New Zealand, Engineer. Improved means of locking nuts on bolts.

Extract from Specification.—According hereto, the bolt has a cylindrical hole at right angles to its axis, in which slides a pin which, when the nut has been screwed up to the required extent, takes into a recess in the nut and thereby prevents it from coming unscrewed. The pin may be projected and retained in its projected position by a bent spring which is passed into a recess in the nut and at its end bears against the end of the pin.

Claims.—(1.) A necktie-frame formed of a single length of spring wire doubled over at its middle to form a bayonet-joint slot adapted to pass over the collar-stud, and with its two ends curved outwards from each other and bent backwards from the slot, in order to form arms adapted to fit within the fold of the collar on the respective sides of the stud, substantially as specified. (2.) The improved necktie-frame constructed substantially as described and explained, and as illustrated in the drawings.

No. 29245.—8th March, 1911.—WILLIAM BENNET, of Mornington, Dunedin, New Zealand, Bootmaker. Improved renewable laced soles and renewable and interchangeable heels for boots and shoes.

Extract from Specification.—I make the whole boot in the usual manner, all except that the middle sole only is secured permanently to the upper, and the heels are only made to part of the height required. The middle sole or welt is formed to project slightly beyond the upper, and is furnished with a row of sewing-holes, preferably lined with eyelets, and the outer sole is grooved in any well-known manner as for sewn soles, and furnished with holes registering with those in the welt or middle sole. The end is provided with a spring to insure its being tight to the boot. The soles are then laced together, and are of the most pliable construction. The heel is furnished with a bent slide, to which the lifts are fitted and slid in, when a clip-stud secures them.

No. 29260.—17th March, 1910.—ARTHUR MARSHALL MCINTOSH, of 157 Macquarie Street, Sydney, New South Wales, Australia, Dentist. Improvements in aeroplanes.

Extract from Specification.—In this invention there are several improvements relating to the wings and rudder of an aeroplane. The first improvement consists in making each wing of the aeroplane in two longitudinal convex arcs. The second improvement consists in turning the front edge of each wing upwards for a quarter or more of the length of the front edge of the wing, the turned-up part being the most remote from the car. The third improvement consists in scalloping the extreme end of each wing, thus forming a kind of terminal wing-pinions with air-spaces between the pinions. The fourth improvement consists in providing a small auxiliary wing at or near the centre of the front edge of each wing. This auxiliary wing may be manipulated from
