Some Recent N.Z. Patents for which Specifications are accepted

Pilot Light of Gas-burner. —George Arthur Pearson, of Christchurch, N.Z., Engineer, 29th September, 1913. This invention consists, briefly, in providing means whereby the turning of the cock to supply gas to the main burner will serve also to momentarily augment the flow of gas to the pilot burner, and so increase the length of the flame of the later for the time being. As when used in conjunction with this invention the normal pilot flame may be reduced to the smallest possible point, a shield or plate is provided to prevent such flame from being accidently extinguished by a current of air. Constructing Ferro-Concrete Structures. —.Frederick George Eortzer, of Auckland, N.Z., Builder. 12th March, 1914. This invention consists in the erection of the walls by the use of previously moulded ferro-concrete studs that are set up at approved distances apart and then have the spaces between them filled in with concrete. Suitable metal reinforcements are threaded horizontally through the several studs so that the whole wall is bound firmly together. The studs are used as the uprights of the framing by which the moulds for the concrete are made, the boards constituting such framing being clamped to the inner and outer surfaces of the studs. If desired, also, each stud may have a wooden batten made fast to it throughout its height by means of wires anchored in the stud. These battens are then used in the attachment of the lining of the walls, whether wood, or lath and plaster, or any other known form. Building-material. — Gustaf Gass, of Christchurch, N.Z., Baker. 30th April, 1913. This material is composed of lime-mortar and small lumps of pumice thoroughly mixed, the compound so formed being rammed or pressed into a mould and then allowed to dry. Preferably the lime-mortar is allowed to stand for approximately eight hours before the pumice is added. Stone-cutting Machine. Frederick Ridley Dennison, of Tyne Street, Oamaru, N.Z., Mechanical Engineer. 7th May, 1913. This machine comprises a frame having saws adjustable vertically, a motor for driving the saws, and drums around which ropes are coiled, the ends of the ropes being anchored. The frame may have saws fixed to a shaft, with bearings sliding vertically, chains attached to the bearings and to drums fixed to a shaft having a hand wheel, a ratchet and pawl on the drum-shaft, an electric motor driving the saws by means of mitre-wheels, a shaft, a worm, and worm- , wheel, and drums around which ropes are coiled, the ends of the ropes being anchored. Fibrous Plaster-of -paris Work. —Archibald Alfred Leman and Clarence Vincent Leman [ trading as “ Leman Brothers, ’of Tui Street, Mount Eden, Auckland, N.Z., Ornamental Cementwork and Fibrous-plaster-work Manufacturers. 28th July, 1913.]

This patent consists of the employment of textile fabric interposed between a facing of plaster, and a backing of plaster mixed with fibre. Kerosene-tin and the Like Handle. — Gordon Garrow, of Oamaru, N.Z., Farmer, 12th March, 1914. This patent consists of a length of wire bent into a rectangular shape, and with a recess supplied with a coil of wire which acts as a handle and gives a secure and comfortable grip. The ends of the wire are bent into hooks, which are passed through the holes, and, if necessary, further bent upwards to complete the attachment. Scrap Iron, Employing in Rolling-mills. — Horne Smellie, of Edinburgh Street, Green Island, Otago, N.Z., Ironmaster. 20th March, 1914. This patent consists in placing the loose pieces of scrap iron in a mould-box and pouring sufficient'molten iron upon it to form a cohesive mass ready to be passed through the mill-rollers. Combined Ruler and Blotter. —John William Boyce, of Emerson Street, Napier, N.Z., Tailor. 11th June, 1913. According to this invention, a cylindrical roller of wood or the like is encased in a sleeve of rubber or other suitable material, which preferably has longitudinal grooves or corrugations upon its periphery. The sleeve in turn is encased in a cylinder comprised of a roll of absorbant blotting material. Each layer of the roll has a line of perforations extending across it, and is also secured by paste or the like to the layer immediately beneath it, so that by cutting through the material near the line of paste the outer layer can be torn off along the line of perforations. The roller is rotatably mounted in a frame (which is provided with a handle) by means of pins which fit axially into the ends of the roller, one pin fitting a hole in the frame, and the other pin into a slot upon the opposite side thereof. A spring catch pivoted at one end upon the frame, and having at its other end a snib which fits a recess in the frame, is employed to prevent the roller-pin from coming out of the slot. Cooking-range. —Newberry, Walker, Limited, of Dunedin, N.Z. [Assignee of Montague William Marriage, of same address, Director of the Company.] 20th June, 1913.
