Claim.—An improved foot for fencing-standards, comprising a plate having one end bent at a right angle and the middle part of the other end similarly bent at a right angle, and having holes through the parts so bent for the reception of the standard, and a pin through the standard for preventing vertical movement of the standard through the foot, substantially as and for the purposes set forth.

(Specification, 2s.; drawing, 1s.)

No. 20758.—22nd February, 1906.—ALFRED ERNEST LUTTRELL, of Balmain, New South Wales, Australia, Cabinet-maker. An improved rotary pump.

Claim.—An improved rotary pump, characterized by a cylindrical chamber divided into two compartments by a disc adapted to revolve, said disc having radial slots and corresponding blades adapted to slide therein. Each of the said compartments being provided with a block and inclined guiding planes, each of which are diagonally opposite to each other, and each compartment being provided with a separate inlet and outlet, as described.

(Specification, 3s. 3d.; drawings, 2s.)

No. 20769.—19th February, 1906.—ARTHUR TEMPLE CLIFTON FIRTH, of “Clifton,” Seccombe’s Road, Mount Eden, near Auckland, New Zealand, Mining Engineer. Metal-plated concrete sleepers for railway or tramway construction.

Claims.—(1.) The fixing of metal plates into the surface of the top and bottom of the concrete sleeper with their ends turned in and with bolt-holes made through said plates and concrete for the purpose set forth, substantially as described and illustrated. (2.) In combination, the metal plates fitted into the top and bottom surfaces of the concrete sleeper with their ends turned in, with bolt-holes made through said plates and sleeper, and the concrete strengthened with iron or steel rods imbedded therein for the purpose set forth, substantially as described and illustrated.

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

No. 20778.—27th February, 1906.—EDWIN CLAYTON POHLÉ, of 732 Mills Street, Reno, Nevada, United States of America, Mining Engineer. Improvements in processes for recovering values from sulfid ores.

Claims.—(1.) The process of recovering values from sulfid ores containing gold and silver, which consists in mixing the ore with a chlorid, subjecting the mixture to heat in an oxidizing atmosphere, cooling the product, leaching the mass with water to remove the contained bodies soluble therein, leaching the residue with a solution of a cyanid of an alkali metal, and finally precipitating the gold and silver from the solution. (2.) The process of recovering values from sulfid ores containing gold and silver, which consists in mixing the ore with a chlorid, subjecting the mixture to the flame of combustion with an excess of air, conducting off the gaseous products, condensing and collecting the metallic vapours, cooling the solid products, leaching the mass with a solution of a cyanid of an alkali metal, and precipitating the gold and silver from the solution. (3.) The process of recovering values from sulfid ores containing gold, silver, and base metals, which consists in mixing the ore with a chlorid, subjecting the mixture to the flame of combustion with an excess of air, conducting off the gaseous products, condensing and collecting the metallic vapours, cooling the solid products, leaching the mass with water to remove the contained bodies soluble therein, leaching the residue with a solution of a cyanid of an alkali metal, and precipitating the gold and silver from the solution. (4.) The process of recovering values from sulfid ores containing gold and silver, which consists in mixing the ore with a chlorid, subjecting the mixture to the flame of combustion with an excess of air, conducting off the gaseous products, condensing and collecting the metallic vapours, cooling the solid products, leaching the mass with a solution of a cyanid of an alkali metal, and precipitating the gold and silver from the solution. (5.) The process of recovering values from sulfid ores containing gold and silver, which consists in roasting the ore in contact with the flame of combustion with an excess of air, conducting off the products of combustion and resulting vapours by a forced draft, condensing the metallic vapours, and filtering them from the permanent gases. (6.) The process of recovering values from sulfid ores containing gold and silver, which consists in mixing the ore with a chlorid, subjecting the mixture to the flame of combustion with an excess of air, conducting off the products of combustion and resulting metallic vapours by a forced draft, condensing the metallic vapours, and filtering them from the permanent gases.

No. 20779.—27th February, 1906.—SAMUEL TAYLOR, of Nos. 145, 146, and 147 Lionel Street, Birmingham, England, Zinc and Galvanised-iron Worker. Improvements in metallic coverings for roofs, walls, and buildings.

Claims.—(1.) In metal-covered or metal roofs, walls, and buildings in which the opposed edges of the metallic sheets are separated a short distance apart, the open joints being covered by guttered covering strips or caps, giving to the opposed or joint edges of the metallic sheets and the joint covering strips or caps such a configuration that longitudinal channels are formed between them for carrying away water of condensation or other water, and preventing the same from gaining, by capillary attraction or otherwise, access to the undersides of the metallic sheets. (2.) The combination with the adjacent edges of the metallic sheets, covering strips or caps, and washers, and fixing screws or bolts of the solid semi-cylindrical blocks situated under the edges of the sheet at the parts where they are to be connected together.

(Specification, 2s. 6d.; drawing, 1s.)

No. 20780.—27th February, 1906.—EMIL HEINRICH BOCK, of 13 St. Georges-Strasse, Hamburg, Germany, Engineer. Improvements in and relating to apparatus for playing a game of skill.

Claims.—(1.) Apparatus for playing a game of skill, comprising, in combination, a box having a glass front, a wall in said box dividing the same into two compartments and having a hole, and a pivoted sickle-shaped lever in the front compartment having a handle extending outside the box, said lever being intended to be operated by the player in such a way that a rolling object such as a coin placed on the lever is at will ejected through the above-mentioned hole in the above-mentioned wall, substantially as described. (2.) Apparatus for playing a game of skill, comprising, in combination, a box having a glass front, a wall in said box dividing the same into two compartments and having a hole, a pivoted sickle-shaped grooved lever in the front compartment having a handle extending outside the box, losing and winning passages in the back compartment of the box, and means adapted when the box is tilted to prevent an object after passing through the above-mentioned hole from entering the winning-passage, said lever being intended to be operated by the player in such a way that a rolling object such as a coin placed on the lever is at will ejected through the above-mentioned hole in the above-mentioned wall into the winning-passage, substantially as described.
