No. 23188.—25th July, 1907.—RICHARD ARTHUR BRADBURY, of Christchurch, Canterbury, New Zealand, Oilskin-clothing Manufacturer. Improvements in waterproof garments.

Extract from Specification.—According hereto the coat has a pair of external flaps and a pair of inner flaps, the edges of one pair of flaps being arranged to meet along a line in a position different from the position in the case of the other pair. When adapted for use on horseback, the inner flaps are shortened and their edges are protected by an exterior plate or flap, and the back skirts of the coat where they are divided to fall over the saddle are connected by an independent flap, which may be folded inside the coat when out of use and secured by any convenient means; or, if desired, flaps corresponding to those used upon the front of the coat may be used upon the skirts at the back. For fastening the flaps together I prefer to employ a special form of fastening, which is attached to the coat by an eyelet and adapted to swing sideways to permit the fastener proper to pass readily through a button-hole.

Specification, 3s. 6d.; drawing, 2s.

No. 23190.—25th July, 1907.—THE HONOURABLE CHARLES ALGERNON PARSONS, C.B., of Heaton Works, Newcastle-on-Tyne, Northumberland, England, Engineer. Improvements in and relating to blading for turbines, compressors, and the like.

Claims.—(1.) Assembling blades in ring, segment, or strip form ready for application to the turbine or compressor groove by providing at their root-ends interconnecting or interlocking means, and staving or caulking the whole in a former so that they shall be consolidated, substantially as described. (2.) Assembling blades in ring, segment, or strip form by providing the roots of the blades and their distance-pieces with holes, notches, recesses, or the like, and passing the blades and packing-pieces over a wire, strip, or tube, and staving or caulking the whole as set forth in claim 1, substantially as and for the purpose described. (3.) Assembling blades in ring, segment, or strip form by providing the distance-pieces with interlocking means, and staving or caulking the whole as set forth in claim 1, substantially as and for the purpose described. (4.) Assembling blades in ring, segment, or strip form by providing the blade with one or more projections, and the distance-pieces with one or more holes or slots or vice versa, said projecting portions engaging with the holes or recesses, and staving or caulking the whole in a former, substantially as and for the purpose described. (5.) Assembling blades in ring, segment, or strip form ready for application to the turbine or compressor groove by bending over a part of the blade-root into a slot formed in the adjacent distance-piece, and caulking or staving up the whole, substantially as and for the purpose described. (6.) Assembled turbine blade rings, segments, or strips in which the roots of the blades and their distance-pieces are staved on a former to firmly grip a wire metallic strip or the like, or are linked together by any chain-grip devices serving to hold the blades together and staved on a former so that they may be transferred as a segment, complete ring, or comparatively flexible strip into the groove or drum of the turbine-casing, substantially as described. (7.) Assembled turbine-blade rings, segments, or strips manufactured substantially as described with reference to Figs. 1 to 4, 5 to 7, and 8 to 10 of the drawings. (8.) Assembled turbine-blade rings, segments, or strips manufactured substantially as described with reference to Figs. 12, 13, and 14 of the drawings. (9.) Assembled turbine-blade rings, segments, or strips having a connecting wire or strip manufactured substantially as described with reference to Figs. 15 and 16 or 17 and 18 of the drawings. (10.) Assembled turbine-blade rings, segments, or strips manufactured substantially as described with reference to Figs. 19 and 20 of the drawings. (11.) In blade rings, segments, or strips made in accordance with claim 1, a serrated or like wire or strip, substantially as and for the purpose described.

No. 23191.—25th July, 1907.—FREDERICK TITCOMB SNYDER, of 301 Ashland Avenue, Oak Park, Illinois, United States of America, Engineer. Process and apparatus for treating ores.

Extracts from Specification.—The process consists, briefly, in smelting the ore of zinc or other volatile metal with a reducing-agent, such as carbon, in the absence of air and preferably in an electric furnace, and preventing the vaporised metal produced from accompanying the other gases in their escape from the furnace, the volatile metal being condensed in the furnace and removed through an opening separate and distinct from that through which the carbon-monoxide and other gases escape. . . . The invention contemplates heating the ore with reducing and fluxing agents in successive stages. . . . Another feature of my invention consists in heating the furnace by passing an electric current through a body of molten slag, and cooling the walls of the vessel sufficiently to congeal the slag around the interior of the walls. . . . A further feature of my invention refers particularly to the operation of an electric furnace with alternating current, and consists in having the current pass into and out of the furnace through the same end of the closed magnetic circuit formed by the water-jacket, whereby the effect of self-induction due to the iron water-jacket is substantially neutralised. My invention also consists in an electric furnace of improved construction suitable for carrying out the above process.

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

No. 23193.—25th July, 1907.—JAMES THOMPSON, of Terania Street, Lismore, New South Wales, Australia, Builder and Contractor. An improved means of hanging and adjusting window-sashes.

Claims.—(1.) In an improved means of hanging and adjusting window-sashes, a pair of pulley-wheels provided one on either side at the top of the window-frame in combination with a pair of cords passing thereover, one end of each of which is attached to the top of the upper sash and the other to the top of the bottom sash. (2.) An improved means of hanging and adjusting window-sashes consisting of a pair of pulley-wheels provided one on either side at the top of the window-frame, and a pair of cords passing thereover, one end of each of which is attached to the top of the upper sash, while the other passes down the side of the frame of the lower sash and is attached to a suitable winding-mechanism provided on the bottom of the lower-sash frame for the purposes set forth, and as illustrated in the drawings. (3.) In an improved means of hanging and adjusting window-sashes, a pair of pulley-wheels and a pair of cords passing thereover as described, in combination with a suitable winding-mechanism for the purpose set forth. (4.) An improved means of hanging and adjusting window-sashes consisting of the parts constructed, arranged, combined, and operating as set forth, and as illustrated in the drawings.

No. 23197.—25th July, 1907.—EDWARD JOHN KEE, of Otama, Southland, New Zealand, Farmer. An implement for cultivating ground containing twitch or other noxious weeds.

Claims.—(1.) A cultivating-implement comprising, in combination, a frame carried on driving-wheels, a scoop or mould-board carried on the frame and formed with a number of slots extending forward from its back edge, a rotating drum mounted across the frame at the rear end of the scoop, and teeth upon such drum adapted to pass through the slots in the scoop as the drum is rotated, substantially as specified. (2.) The general arrangement, construction, and combination of parts in my implement for cultivating ground containing twitch or other noxious weeds, substantially as described and explained, as illustrated in the drawings, and for the several purposes specified.
