No. 28427.—14th September, 1910.—THOMAS EDWARDS, of Webster Street Ballarat, Victoria, Australia, Metallurgist. Improvements in ore-roasting furnaces.

Extract from Specification.—I provide superimposed hearths, but may heat and use only one hearth, or two or more (not in communication with each other) are heated and used at once. Each hearth has an independent end fireplace, at the same end and accessible from the same side of the furnace, one not immediately above the next, but in an oblique line therefrom. Rabbles are rotated, but not all at one speed; they are in one or more longitudinal rows, with stems projecting into the bottom hearth. The same mechanism that drives the rabbles drives ore-feeding means to supply the (or each) hearth, and ore-discharge or dropper means. The raw ore or other material is automatically introduced in an advantageous manner, using screw feed. The ore-discharge or dropping means is arranged to readily permit of the cleaning and renewal of parts, and to act as a dust-preventer. Any current of air passing up into the furnace through a plain discharge-hole would carry valuable metalliferous dust from the roasted ore back through the furnace, and out of the latter into the flues. This would involve loss, as roasted ore thus carried off becomes mixed with arsenical or other flue-deposits. If there is a plain drop of hot rabbled ore from one hearth to another, undue dust is also created in the furnace, and part becomes lost in the flues.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 13s. 6d.)

No. 28428.—14th September, 1910.—THOMAS EDWARDS, of Webster Street, Ballarat, Victoria, Australia, Metallurgist. Improvements in feeding-devices for ore-roasting furnaces and the like.

Claims.—(1.) An ore-roasting-furnace feeding-device, having means driven from a main shaft (which causes rabble-rotation) for turning simultaneously a series of screw conveyors in a hopper, having above said conveyors a series of boards or members which are movable to allow fall of ore, substantially as described.

[NOTE.—Here follow five other claims.]
(Specification, 4s. 6d.)

No. 28434.—14th September, 1910.—THE HELI-CUSHION DRIVE, LIMITED, a registered company of the State of New South Wales, Australia, having its offices at Mutual Life Association Building, Wynyard Street, Sydney, in the said State (assignees of Herbert Ernest Ross, of No. 350 George Street, Sydney, in the said State, Consulting Engineer). An improved spring drive or power-shaft coupling (B).

Extract from Specification.—This improved spring drive or power-shaft coupling comprises four main parts—(a) a positively operating helical feather or way or male or female thread on the one end of a shaft, say, the driving-shaft; (b) a box or casing or framing on the end of the meeting shaft or, say, driven shaft; (c) a nut or sliding block having a helical way or feather or female or male thread complementary to that on the driving-shaft end, and within and rotatively controlled by a box or casing or framing on the driven-shaft end; and (d) a compressible spring or compressible springs between said nut or sliding block and the ends of said box or casing or framing on said driven-shaft end.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 5s. 6d.)

No. 28440.—14th September, 1910.—HENRY SCHLAADT, of Cumberland Street, Dunedin, New Zealand, Engineer. Improved strong-room doors.

Extract from Specification.—The object of this invention is to apply balls to support either the weight of heavy strong-room doors, or else to support the weight and the thrust of same. For this purpose I form a chase round the pivot and also round the socket of same, between which I place the balls, the said chases being formed for the purposes above mentioned, as may be needed.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 2s. 3d.

No. 28444.—17th September, 1910.—FREDERICK JOHN NORTHCOTT, of Christchurch, New Zealand, Manufacturer’s Agent. Improved means for use with milking-machines for receiving and delivering the milk.

Extract from Specification.—The can is divided centrally into two equal divisions, and is provided with a single receiving-chamber on its top, which chamber is provided with a vacuum connection and with connections by which the main milk-flow pipes may be led into it. A valve of special design is arranged between this chamber and the can, and such valve is so constructed that either of the can-divisions may be connected with the chamber while the other is cut off, and whereby also air may be admitted at the same time to this latter division while being excluded from the former. Each division of the can is provided with a gauge-glass of ordinary design so that the height of the milk delivered into the division may be read, and this glass is marked with a scale approximating to the weight or quantity of the milk in the division at the corresponding heights thereon. Each division is also provided with a draw-off cock in its lower end.

(Specification, 5s. 3d.)

No. 28461.—20th September, 1910.—ANNE OF LOWENSTEIN WERTHEIM, of 8 Upper Belgrave Street, London, England, a Princess of the German Empire. Improvements in connection with self-levelling cots, bunks, couches, and the like, for use on board ship.

Claims.—(1.) In self-levelling cots, bunks, couches, and the like, swung in gimbals, for use on board ship, the combination of an elastic-band brake with the gimbal-trunnions, constructed and arranged substantially as described and shown. (2.) In self-levelling cots, bunks, couches, and the like, swung in gimbals and provided with elastic-band brakes upon the gimbal-trunnions, the combination therewith of the spring-cushion connection between the cot and its suspending-rods, substantially as described and shown.

(Specification, 4s. 6d.)

No. 28463.—20th September, 1910.—MURDOCH MCDONALD, of Clunes, Victoria, Australia, Agricultural-implement Maker. Improvements in railway signalling mechanism.

Claims.—(1.) In signal mechanism, the combination with a train-wheel spring-contact member having a normally raised flat top with downwardly extending ends, of connecting-means to a mast and treadle which rise to act as danger-signals when a train-wheel depresses the contact member, said means including a shaft having an inner lever-arm under said member, an outer lever-arm connected to a weight having means for rapid rise and slow descent, and wires or the like.

[NOTE.—Here follow four other claims.]
(Specification, 11s.)

No. 28474.—22nd September, 1910.—GEORGE HERBERT BAILEY, of Emu Flat, Major’s Creek, New South Wales, Australia, Police Constable. Improvements in and relating to the manufacture of gloves.

Extract from Specification.—Forming gloves from such skins as rabbit-skins by just removing the skins from the body in a tubular form, then tying the two fore legs and the neck, and finally stretching the green skin over a mould or stock in such manner that the two fore legs form the second and fourth fingers, the neck the third finger, and stretching the remaining portions of the skin over the mould or stock to form the thumb and the first finger and the body of the glove.
