No. 12668.—8th June, 1900.—CHARLES BEDE TREFLE, of Temora, New South Wales, Farmer. Equaliser for yoking six or three horses.

Description.—Swingle-bars A, A, with pulleys B, B, and C, C, on each end, and fastened to a large swingle-bar from points D, D, one-third from inner ends of aforesaid swingle-bars, and ropes or chains E, E, running through pulleys B, B, with pulleys H, H, H, H, on each end, through which run ropes or chains I, I, I, I, from leading horses, said ropes or chains with similar ropes or chains passing through pulleys C, C, to act as traces, and to be fastened to hames of leading horses at points L, L, L, L, L, and to back horses at points K, K, K, K, K, thus making the portions of the weight of the load drawn by the team at the points K, K, K, K, K, K, equal, and the portions of the weight at the points L, L, L, L, L, equal, and weight at the points K, K, K, K, K, K, equal to the weight at the points L, L, L, L, L, thereby compelling each horse to bear its equivalent portion of the weight of the whole load. The equaliser, when required for three horses, is adjusted by removing leading tackling, together with chains E, E, and putting short ropes or chains from hames of inner back horse through pulleys B, B, and on to hames of outer back horses, and single traces from the ends C, C, to hames of outer horses, the whole as shown on drawing.

Claim.—A combination of three swingle-bars with pulleys and ropes or chains, as described above and specified, and as illustrated in the drawings.

No. 12674.—12th June, 1900.—SAMUEL BENJAMIN ALLISON, of S½ and Thirty-fifth Streets, Galveston, Texas, United States of America, Mechanical Engineer. Improvements in machines for separating the fibres of plants.

Claims.—(1.) The combination of rollers to crush stalks, scutching-devices situated immediately below one of said rollers, and a block situated between the rollers, said block having a working-face curved to correspond to one of the rollers, and extending from the point of operative contact of the rollers to a point adjacent the scutching-devices. (2.) In a machine for separating the fibre of plants, the combination of a grooved feeding-belt, and a roller having annular guides registering with the belt-grooves. (3.) In a machine for separating the fibre of plants, the combination of a stalk-feeding device, blades to split the stalks, and a stalk opening and flattening roller having operative faces corresponding in number and plane of rotation with the blades, and a roller co-operating with said stalk-opening roller. (4.) In a machine for separating the fibre of plants, the combination of the wood- and fibre-separating blades, a block having a working-bed, means for splitting the stalks and presenting their woody side to said blades to separate the wood, and pins to follow the blades. (5.) In a machine for separating the fibre of plants, the combination of coasting rollers, a block having a working-bed conformed to one of the rollers and extending to near their proximate lines, a reciprocating scutcher, a hinged plate to receive the fibre from said scutcher, and a tool-carrying roller coasting with the bed. (6.) In a machine for separating the fibre of plants, in combination with a working-bed, the wood-separating blades carrying combing-pins, said blades having receptacles for fine refuse combed out of the pins. (7.) In a machine for separating fibre, the combination of the several blades to split each one side of a stalk, an endless feeding-belt, a stalk supporting and guiding roller coasting with the belt and having grooves embracing each a stalk and holding them against the transverse action of the knives, and the flattening- and breaking-rollers situated in proximity to the blades. (8.) The combination of a feeding-belt with a roller having circumferential grooves to embrace and sustain the sides of the stems without splitting or crushing them and maintain their parallelism on the belt, said belt having an elastic support adjacent said roller. (9.) In a machine for separating fibre, in combination with a slotted bar to beat the fibre, a fixed bar correspondingly slotted and having tracks for the reciprocating-bar bearing on its face. (10.) In a machine for separating fibre, the combination of a fixed slotted bar and a reciprocating slotted bar to beat the fibre, said fixed bar being provided with ball bearings for the reciprocating bar.

No. 12679.—13th June, 1900.—EDWARD WATERS, Jun., a member of the firm of Edward Waters and Son, of 131, William Street, Melbourne, Victoria, Patent Agent (nominee of the Illinois Reduction Company, a corporation duly organized and existing under the laws of the State of Illinois, United States of America, having its principal office at Room 904, No. 115, Monroe Street, Chicago, Illinois aforesaid, Manufacturers, the assignees of Elias Anthon Smith and Marcus Hartmann Lyng, of Stevens, Washington, United States of America, Chemists). Improvements in methods of extracting precious metals from their ores.

Claims.—(1.) The method of extracting precious metal from ores which consists in forming a leach-liquid by admixture of an alkali-metal oxychloride solution—e.g., sodium-oxychloride—with free sodium-chloride, digesting the pulverised ore suspended in such liquid in the presence of a free acid—e.g., hydrochloric acid—to release the chlorine and effect solution of the gold and silver (and copper, if present), precipitating said metals from the separated solution by addition of suitable reagent, and, upon removal of such resultant precipitates, electrolytically treating the properly neutralised solution so as to directly convert into oxychloride the alkali-metal chloride present in said solution, and thus to regenerate it for re-use, substantially as described. (2.) The method of extracting precious metals from ores which consists in suitably electrolysing an alkali-metal chloride solution—e.g., sodium-chloride—to form in part oxychloride, leaving sodium-chloride in excess in the resultant leach-
