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.

No. 23749.—21st November, 1907.—JOHN STURDIDGE DREADON, of Mititai, Northern Wairoa, Auckland, New Zealand, Farmer. An improved grindstone.*

Extract from Specification.—According to this invention, suitable grinding-material, which may be of stone or of other approved nature, is secured within the periphery of two wheels mounted upon a shaft adjacent to each other, in such a manner that the adjacent surfaces of the grinding-material will be in juxtaposition and revolve together. These surfaces are tapered inwards so that the two together form a wedge-shaped opening into which the tapered edge of a tool is adapted to fit in order that both faces of the tool may be ground. One wheel is fixed on the shaft, while the other is made free to slide to and fro on it, while being arranged to rotate therewith. Means are provided whereby the position of the movable wheel may be varied with regard to the fixed wheel in order that the width of the opening between the grinding-faces may be regulated.

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

No. 23972.—6th February, 1908.—ALFRED ROBERT HALE SWINDLEY, of Coromandel, New Zealand, Shipping Agent. Improvements in registering mariners’ compasses.*

Claims.—(1.) In combination, a compass, a vertical terminal arranged upon the compass-card, a pair of arms pivoted to the compass-case and adapted to extend one on each side of the terminal upon the card, an electric alarm and annunciator circuit, and electrical connections between the terminal upon the card and one pole of such circuit, and between the pivoted arms and the other pole of the circuit, substantially as and for the purposes specified. (2.) The improvements in registering mariners’ compasses substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 23973.—6th February, 1908.—JOHN ANDREW MILLAR, of Wellington, New Zealand. An improved rowlock.*

Extract from Specification.—According to this invention, the rowlock is constructed with a stem having its upper portion divided into two and hinged to the main portion. The arms or forks are made in one with the respective hinged portions, and the hinges are arranged in such a manner that they will be capable of turning down and outwards from each other, or of standing up together so as to be adapted to receive the oar. A socket-piece is attached to the boat’s gunwale, this socket-piece comprising a vertical sleeve adapted to lie against the inside of the gunwale and to receive the stem of the rowlock. The stem, after being inserted, has a cross-pin or the like secured upon its bottom end so as to prevent it being lifted out of the sleeve.

No. 24066.—28th February, 1908.—ROBERT TACON, of Christchurch, New Zealand, Chaff-cutter. Improved spark-arrester for locomotive or like boilers.*

Claims.—(1.) In spark-arresters for locomotive and like boilers, consisting of a cap or hood supported above the top of the funnel, and provided with a convex undersurface, a receptacle for the sparks formed around the bottom edge of the hood and constructed by turning such edge inwards and upwards, and provided with a flange extending outwards from the top extremity of such edge and over the receptacle thus formed, substantially as specified. (2.) The general arrangement, construction, and combination of parts in my improved spark-arrester for locomotive or like boilers, substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

(Specification, 2s. ; drawing, 1s.)

No. 24105.—7th April, 1908.—ALEXANDER COLIN MURRAY, of Timaru, New Zealand, Commission Agent. An improved bucket-handle for kerosene-tins and the like.*

Claim.—The handle for kerosene-tins and the like, comprising, in combination, a handle mounted on a suitably bent frame, means for holding the handle to the frame, and means for holding or fastening the frame to the tin, substantially as described.

(Specification, 1s. ; drawing, 1s.)

No. 24111.—9th March, 1908.—OSKAR BREDEHORST, of Kimbolton, New Zealand. An improved construction of spring cart.*

Claims.—(1.) The improved construction of spring cart characterized by the use of helical springs arranged to suspend the cart-body upon the axle. (2.) In spring carts, helical springs extending transversely outwards from each side of the axle, attached at their inner ends to such axle, and at their outer ends to the cart-body, substantially as specified. (3.) The improved construction of spring cart substantially as described and explained, and as illustrated in the drawings.

No. 24197.—31st March, 1908.—JOSEPH STEPHENS, of Riversdale, Southland, New Zealand, Inventor. An improved combined mouse- and rat-trap.*

Extract from Specification.—The invention relates to the class of traps in which a wire loop is sprung over upon the animal to be killed. The main feature of my invention consists in the striking arrangement. Instead of placing the bait upon a suspension hook as hitherto, the bait is placed beneath a wire trip which is pivoted upon the foundation-plate, and has a loop to receive the end of a pivoted wire lever, which passes over and retains the catching-loops.

No. 24249.—9th April, 1908.—LOUIS TASMAN REICHEL, of 62 Rolleston Street, Wellington, New Zealand, Electrician, and EDWIN FREDERICK REICHEL, of 71 Wright Street, Wellington aforesaid, Electrician. An improved fire-alarm.*

Extract from Specification.—The invention consists in the utilisation of a thermopile to produce a current of electricity sufficiently strong to actuate a galvanometer, which in turn will cause an electric alarm circuit to be closed when the galvanometer pointer has been deflected a certain regulated distance. The thermopile will be so constructed that it may be secured upon a ceiling or wall of a building, and any desired number of such thermopiles may be arranged in series with the galvanometer. The thermopile will be also so formed that a current of sufficient strength to actuate the galvanometer pointer the required amount will only be generated upon a sudden rise of temperature occuring in its vicinity.
