No. 26828.—2nd November, 1909.—EDWARD BRICE KILLEN, of 52 Queen Victoria Street, London, England, Engineer. Improvements in wheels with detachable rims or tires.

Extract from Specification.—I build my easily detachable wheel proper A from two round suitable stamped-steel dishes, which I will call front and back steel dishes A1 and A2, and which, when properly made, fitted, and locked together, with wood or other suitable light material between them, form my strong, light, rigid, and truly circular wheel proper A. The steel dish A1, which forms the front of my wheel proper A, is stamped dish-shape with the required obtuse angle at its truly circular, outwardly slanting, bevelled circumference (see Figs. 1, 2, 3, 4, 5, and 6), and into this stamped truly circular front steel dish A1 is suitably fitted wood or other suitable light material, filling up suitably the space inside front dish A1, after which my back steel stamped dish A2, which is also formed truly circular, having the extreme outer circumference not bevelled but at right angles to the dish itself—like, say, the round metal lid of a box—is made and constructed to be fitted tightly over the extreme diameter of the outwardly bevelled circumference of the front dish A1, which forms the front of my wheel proper A.

No. 26829.—2nd November, 1909.—JOHN SLORACH, of the Geldenhuis Estate and Gold-mining Company (Limited), Cleveland, Johannesburg, Transvaal. Improvements in valve devices for reciprocating engines.

Claims.—(1.) In an engine of the class specified, the combination of the valve 12 having flat end faces 13 and 14, and the detachable valve-seating comprising a perforated end member 15 carrying a threaded spindle 18, upon which the valve is loosely mounted and upon which the second perforated end member 16 is screwed, said valve-seating being adapted to be held in the walls of the valve-chest by a plug bearing upon the loose disc, substantially as described. (2.) In an engine of the class specified, a longitudinally guided distributing-valve having substantially flat end faces and corresponding apertured valve-seats with which such valve-faces make contact alternately. (3.) In an engine of the class specified, a valve and valve-seat so constructed that the travel of the valve may be altered. (4.) In an engine of the class specified, and having a valve movable parallel with the piston, an induction-port from the front of the cylinder leading to the rear of the valve, and an induction-port from the rear of the cylinder leading to the front of the valve.

(Specification, 5s. 6d.)

No. 26835.—2nd November, 1909.—ALEXANDER JOHN ARBUCKLE, of 1 Main Street, Belgravia, near Johannesburg, Transvaal, Mechanical Engineer. Improvements in tanks or vessels for separating comminuted solid matter, such as pulverised ore, from liquids.

Extracts from Specification.—The parts providing the depositing or settling areas or surfaces are arranged at such an angle or inclination that the solid particles which accumulate thereupon ultimately gravitate or fall off said areas or surfaces to the bottom or lower portion of the vessel, whence they are removed, either continuously or intermittently, by any suitable means. . . . For the purpose of my invention the vessel may be in the form of an inverted truncated hollow cone or pyramid, or be of circular, square, or any suitable polygonal horizontal section in its upper portion, and of inverted conical or pyramidal shape in its lower portion.

[NOTE.—The above extracts from the specification are inserted in place of the claims.]

(Specification, 14s.)

No. 26836.—2nd November, 1909.—ALEXANDER JOHN ARBUCKLE, of 1 Main Street, Belgravia, near Johannesburg, Transvaal, Mechanical Engineer, and ALFRED OSBORNE, of 1 Main Street, Belgravia, aforesaid, Mine-manager. Improvements in means for separating pulverised ore or other comminuted solid matter from liquid.

Extracts from Specification.—In the vessel, and preferably above the point or points at which the pulp or mixture is introduced, we arrange a suitable number of super-positioned plates or flat surfaces to provide a large area upon which the particles of ore or other solid matter can settle. . . . In each plate or surface, or between contiguous plates or surfaces of each tier, one or more slots, holes, or passages are provided; the slots, holes, or passages in all the tiers preferably coincide, so that an unobstructed passage for the settled solids is provided from the top to the bottom of the vessel. The slots, holes, or passages in the several tiers preferably gradually increase in width in each succeeding tier from the top to the bottom of the vessel. Each slot, hole, or passage also preferably gradually increases in width from the centre to the side of the vessel. Means are provided for scraping or removing the settled solids off the plates or surfaces, and delivering the same over the slots, holes, or passages, through which they fall to the bottom of the vessel.

Extract from Specification.—According to my invention I provide a frame of suitable size, and support same from the wall or door of a room. The frame comprises a board carrying at each end a suitable bracket which supports a rod or bar parallel to the board, also a second rod for the rings of a sliding curtain of flexible material, such as cretonne.

No. 26841.—4th November, 1908.—WILLIAM HOY, of 53 Nickson Street, Surry Hills, Sydney, New South Wales, Australia, Labourer, and JOHN DOWNES, of 73 Cleveland Street, Redfern, Sydney aforesaid, Fireman, and ROBERT WILLIAM GRIERSON, of 58 Pitt Street, Redfern aforesaid, Town Clerk. Improvements in smoke-consuming and fuel-economizing apparatus.

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

Extract from Specification.—According to our invention we provide a baffle-plate which is arched or approximately semi-circular in cross-section, said plate extending from the door almost to the rear of the fire-box in the case of furnaces for vertical boilers, but not so far in the case of furnaces for horizontal boilers. In addition to the said baffle we preferably secure below same a perforated plate of the same cross-section, maintaining a space between the two plates by means of distance-pieces, but said perforated plate does not extend to the length of the upper one.
