Claims.—(1.) In gold-saving dredges, more especially those that strip loam or agricultural land overlying gold-bearing wash, in combination, the tailings-elevator or a similar elevator being brought into such a position that its receiving end is as near as possible, practically, to the delivery end of buckets, and arranged so that when lifting other than gold-bearing wash the buckets deliver to the elevator as direct as possible, all substantially as shown on the drawing and as described and explained. (2.) In gold-saving dredges of the bucket or suction type, the combination of a tailings-elevator having its receiving end brought close to the delivery of elevated material, so arranging that non-gold-bearing material can be delivered direct to said elevator, said elevator being provided with means of having its outer end raised or lowered, and furnished with a swinging chute for better distribution of the material, all substantially as set forth, and as shown on the drawing. (3.) In combination, on a gold-saving dredge, the usual tables, or screen and tables, with an elevator for removing non-gold-bearing material, so arranged that either the screen or tables or the direct elevator can be geared by a chute to the bucket or suction delivery of a dredge, all substantially as set forth, and as shown on the drawing.

No. 16712.—30th July, 1903.—HILARY QUERTIER, of Dunedin, Otago, New Zealand, Engineer. Improvements in and relating to machinery employed for excavating, raising, screening, and filling gravel, ballast, and the like.

Claims.—(1.) For the purpose indicated, a shute having a circular flange upon its upper end adapted to bear upon a fixed ring, whereby said shute may be swivelled to a desired angle, substantially as specified and illustrated. (2.) In a machine for the purpose indicated, outrigger apparatus for preventing side-tipping of the machine, consisting of the parts arranged, combined, and operating as specified and illustrated in the drawings. (3.) In a machine for the purpose indicated, apparatus for preventing side-tipping of the machine, comprising, in combination, a girder fixed beneath the truck-frame of the machine and projecting laterally therefrom, a tee-shaped bracket upon the outer end of said girder, a wheel within a bracket mounted upon said tee-shaped bracket, a screw spindle passing through an eye upon the outer end of the tee-shaped bracket, screwing into a threaded hole in the wheel bracket, a spiral spring encircling the screw spindle between a collar fixed thereon and the under-side of said eye, and a hand-wheel upon the outer end of said spindle, substantially as specified and illustrated. (4.) In a machine for the purpose indicated, means for propelling the machine from a motor thereon, comprising, in combination, a horizontal shaft revolved by said motor, bevel pinions upon opposite ends of a sleeve sliding upon a feather upon said shaft, means for operating the sleeve, a bevel wheel upon a vertical shaft engageable by one or other of the pinions upon the sleeve, a bevel wheel upon the bottom of the vertical shaft gearing with a bevel wheel upon a horizontal shaft, upon which is a sprocket wheel connected by a sprocket chain with another sprocket wheel upon an axle carrying travelling wheels of the machine, substantially as specified. (5.) In apparatus of the nature indicated, means for raising a bucket ladder, comprising, in combination, a sheave revolvably mounted upon the side of the ladder, a sheave carried in a block suspended from a gantry, a wire rope led around said sheaves and fixed at one end to said block or to the gantry, and a winch having a drum which receives the opposite end of said rope, substantially as and for the purposes specified and illustrated. (6.) In apparatus of the nature indicated, means for revolving a cylindrical screen, comprising, in combination, a motor-driven shaft, a sprocket wheel thereon, a friction-clutch in connection with said sprocket wheel operable by a lever, a chain connecting said sprocket wheel with another sprocket wheel upon a countershaft, and a pinion upon said countershaft gearing with a bevel wheel upon the screen, the screen being supported upon friction runners, substantially as specified and illustrated.

No. 16713.—29th July, 1903.—JOSÉ BAXERES DE ALZUGARAY, of Lola Villa, Bromley, Kent, England, Chemist and Metallurgist. Improvements in the manufacture of iron and steel and their alloys.

Claims.—(1.) The process of manufacturing iron and steel and their alloys from the ore, and consisting in pulverising the ore, mixing it with an excess of carbon and a flux and refining agent to produce a carburised material, compressing the same into bricks, mixing pulverised ore with a binding-material, a flux, and a refining agent to produce a non-carburised material, compressing the same into bricks, fusing the two kinds of bricks, or one or other of them, in a suitable furnace, together with pig-iron, scrap, and residues from former operations, ferro-manganese, and other alloys, as described. (2.) The process of manufacturing iron and steel and their alloys from the ore, and consisting in pulverising the ore, mixing it with an excess of carbon and a flux and refining agent to produce a carburised material, compressing the same into bricks and fusing these bricks with similar bricks of a non-carburised material, composed of ore, a binding-material, and a flux and refining agent, all as described. (3.) In the process of manufacturing iron and steel and their alloys, mixing the ore with materials to form carburised and non-carburised bricks containing fluxing and refining agents, and fusing the two together in varying proportions in a suitable furnace, as described. (4.) In the process of manufacturing iron and steel and their alloys, producing refined pig-iron by pulverising the ore, mixing the same with pulverised carbon in excess and lime and water, adding thereto refining and fluxing elements, compressing the mixture into bricks, and subjecting the bricks thus obtained to the action of heat in the usual way, as described. (5.) In the process of manufacturing iron and steel alloys, forming the metal or element to be alloyed into bricks, which will then be mixed with the iron-ore bricks or slabs, or with a molten bath of pig-iron. (6.) In the process of manufacturing iron and steel and their alloys, introducing bricks of non-carburised material into a bath of molten pig-iron, as set forth.
(Specification, 5s.)

No. 16721.—31st July, 1903.—ROBERT CRESSWELL, of Spring Creek, Marlborough, New Zealand, Blacksmith. An improved finger for reaping, mowing, and binding machines.

Claims.—(1.) A finger for harvesting-machines and the like, comprising a body portion having converging upper and lower edges, the upper edge terminating in a horn and the lower edge in a heel, a recess being formed in the rear of said body portion between said horn and heel, a narrow web section formed between and connecting said upper and lower edges, and a removable ledger-plate secured in a groove extending forwardly from said recess, substantially as specified. (2.) A finger for harvesters and the like, comprising a body portion having an enlarged overhanging upper edge inclined downwardly toward the point of the finger, and a lower edge inclined upwardly toward the point of the finger, a recess being formed in the rear portion of the finger between said upper and lower edges, forming a horn upon the rear portion of said upper edge, a narrow web section formed between said upper and lower edges, a heel upon the rear portion of said lower edge, and a ledger-plate removably secured in a forwardly extending groove in said finger, substantially as specified.
