Claims.—(1.) In acetylene-generators of the class having generating-chambers arranged in a water-tank and opening into vertical tubes arranged in such tank, forming each of such tubes with a number of rows of apertures arranged at intervals in its height, each row being arranged in a line inclining upwards round the tube, while the holes of the lower rows are made of greater size than those of the rows above, substantially as and for the purposes specified.

(2.) In a combined sewing and indenting or stitch-separating machine, the provision of a single means that can not only throw the indenting or stitch-separating device into or out of operation, but can also adjust the mechanism that controls the length of the stitches. (3.) A constructional form of the means claimed in preceding claiming clause No. 1 for throwing the indenting or stitch-separating device into or out of operation, comprising a member (such, for example, as 11), an actuator (such, for example, as 12) therefor, and means (such, for example, as 15, 16, 17, 18) for moving said member into or out of range of the actuator. (4.) The improved mechanism for throwing the indenting or stitch-separating device into or out of action, and for operating the feed-regulating means, substantially as illustrated in the accompanying drawings, with or without the “lost motion” device constituted by the parts 21, 23, 24.

No. 22329.—21st January, 1907.—JOHN LOWDEN, Jun., of Mataura, Southland, New Zealand, Blacksmith. Preventing punctures and increasing pneumatic power of cycle and other similar tires.*

Claim.—In pneumatic tires, a ring placed between the inner tube and outer cover, composed of a number of springy metal plates, each curved transversely to conform to the curve in the tire, overlapped end to end, and secured together by means of rivets passing through the lapped portions, substantially as and for the purposes specified, and as illustrated in the drawings.

No. 22451.—21st February, 1907.—THOMAS ROLLEY, of Vulture Street, East Brisbane, Queensland, Australia, Engineer. Improved means for operating casement windows, fanlights, and the like.*

Claim.—In means for operating casement windows, fanlights, and other similar windows and shutters, consisting of a reciprocating rod or bar, carried in bearings, affixed adjacent to the window and prevented from turning therein, and having a helix formed on a portion thereof on which rides a radial arm capable of turning on said rod, but prevented from moving sideways, said radial arm being articulated to the window-sash, substantially as described.

(Specification, 3s. 6d. ; drawing, 1s.)

No. 22472. — 28th February, 1907.—ARTHUR WILFORD STONE, care of Messrs. Stone Bros., of Boston Place, off Church Street, North Fitzroy, Victoria, Australia, Boot-manufacturer. An improved hide- or skin-measuring machine.*

Extract from Specification.—The object of my invention is to provide a cheap, effective, and reliable machine for measuring hides or skins, or other irregularly shaped surfaces, in an original and novel manner. My invention consists essentially in placing the hide or skin to be measured upon a stationary table or skeleton frame having dropper or weight holes therein, causing a dropper plate or frame having therein vertically movable droppers or weights to descend upon or near to the hide or skin, some of the droppers so lowered being retained upon the hide or skin, and some passing through the dropper-holes in the stationary table or skeleton frame, causing the droppers passing through a skeleton frame to descend upon a weighing-platform, which platform by the weight of said droppers descends and by a suitable means of leverage operates a pointer in front of a dial, said dial being graduated to indicate the area or measurement of the hide or skin, and any other indications which may be deemed necessary under various and differing circumstances.

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

No. 22630.—2nd April, 1907.—ERIC HOLLOCOOMBE CLIFF, of 51 Sinclair Road, West Kensington, London, England, Engineer. Improvements in and relating to internal-combustion engines.*

Claims.—(1.) In an internal-combustion engine having an inlet-valve concentrically arranged within the exhaust-valve, mounting the said valves within a detachable annular box adapted to be fixed in the cylinder-head, and provided with means whereby it may be water-cooled independently of the cylinder-head, as set forth. (2.) In an internal-combustion engine having the inlet-valve concentrically arranged within the exhaust-valve, forming a vaporising-chamber between the stem of the inlet-valve and the inner wall of the hollow stem of the exhaust-valve, and packing said chamber or a part thereof with metallic balls or their equivalents, as set forth. (3.) A vaporiser for internal-combustion engines as specified in claim 2, means whereby the balls or their equivalents may be agitated, as set forth. (4.) In an internal-combustion engine having the valves arranged as specified in claim 1, forming a vaporising-chamber between the stem of the inlet-valve and the inner wall of the hollow stem of the exhaust-valve, packing said chamber or a part thereof with metallic balls or their equivalents, and means whereby said chamber may be heated, as set forth. (5.) In an internal-combustion engine having a fuel-feed device, a fuel-feed pipe connected therewith by means of a socket joint, constructed and arranged substantially as described and shown. (6.)
