No. 25631.—3rd March, 1909.—WILLIAM VANDYKE WATSON, of Matehuala, San Luis, Potosi, Mexico, Chemist and Metallurgist. Process for the precipitation of precious metals from cyanide-solutions containing the same.

———

Claims.—(1.) A process for precipitating precious metals from cyanide-solutions containing said precious metals, which consists in bringing said value-containing solutions into contact with zinc in finely divided form, under conditions precluding the presence of oxygen in quantities sufficient to affect the chemical reactions, causing practically all of said metals contained in said solutions to be precipitated out of solution by reaction with the zinc. (2.) A process for precipitating precious metals from cyanide-solutions, consisting in bringing said solutions into intimate contact with finely divided zinc, without the assistance of oxygen from any source whatever. (3.) A process for precipitating precious metals from cyanide-solutions containing said metals, by agitating said solutions in contact with finely divided zinc, the operation being conducted in airtight receptacles and under exclusion of atmospheric oxygen. (4.) A process for precipitating precious metals from cyanide-solutions containing said metals, by electro-deposition in the known way, the operation being conducted in airtight receptacles under exclusion of air.

No. 25644.—5th March, 1909.—KENNETH DOUGLAS DUNCAN, of 3 Halswell Street, Wellington, New Zealand, Clerk, and ALEXANDER GILBERT HUTCHINSON, of Roseneath, Wellington aforesaid, Machinist. Improved overhead driving-gear for shearing-machines.

———

Extract from Specification.—According to our invention, a very simple gear is provided, which requires a minimum of power to drive it, which has few wearing parts, and which runs with almost an entire absence of noise. It is also particularly easy of erection in low and frail shearing-sheds. In connection with our invention we employ a pulley revolved in a vertical plane from the source of power, and connected by a skew belt with a smaller pulley which revolves in a horizontal plane, the result being thus to convert vertical rotary motion into horizontal rotary motion in a well-known manner. According to our invention, the small pulley is concentric with and runs freely about a vertical spindle with which it may be coupled when desired by clutch mechanism. The bottom of this spindle is connected by any usual means with the flexible medium which drives the shears. The respective pulleys are mounted upon brackets as described.

No. 25651.—6th March, 1909.—THOMAS FRANCIS LEIHY, of Auckland, New Zealand, Civil Servant. Improved apparatus for use in branding eggs and the like.

———

Claims.—(1.) Apparatus for branding eggs and the like, the same consisting of a frame adapted to be suspended upon a fixture, and a pair of rubber or other impression stamps upon the outer surface of the frame, substantially as specified. (2.) Apparatus for branding eggs and the like, comprising, in combination, a frame adapted to be suspended against a fixture, a pair of rubber or other impression stamps upon the outer surface thereof, and an inking-pad pivotally attached to the frame and adapted to turn in on to the stamps, substantially as specified.

No. 25652.—4th March, 1909.—WILLIAM MORTON, of Princes Street, Dunedin, New Zealand, Mechanical Engineer. Further improvement in automatic feathering floats for current or paddle wheels.

———

Extract from Specification.—The object of this invention is to set forth an improved method of automatic feathering, especially for the larger variety of wheels, where the weights and springs used in my former invention might require to be of too large a size to be convenient. For this purpose I form a specially formed single or double cam, which guides the floats when in the water to the desired positions during that time, as well as during the rest of the revolution of the wheel to which they belong.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 25653.—4th March, 1909.—JOHN BEATTY, of 9 MacLaggan Street, Dunedin, New Zealand, Grocer. Improved escritoire.

———

Claims.—(1.) In combination with a pedestal table, a well-hole, a cabinet adapted to fit the said well-hole, weights for the purpose of balancing the said cabinet, and cords connecting the said weights and cabinet, all substantially as and for the purpose set forth, and as illustrated in the drawings. (2.) In an improved desk the combination and arrangement of parts substantially as described, and illustrated in the drawings.

No. 25654.—5th March, 1909.—JOHANN FRIEDRICH LUTJOHANN, of Christchurch, New Zealand, Billiard-table Manufacturer. Improvement in the construction of cushions for billiard-tables.

———

Extract from Specification.—In carrying the invention into effect the usual construction of cushion is adhered to, and the rubber portion thereof is formed of the ordinary layers or strips of rubber, which are built up one upon the other till the necessary thickness and shape are provided. Imbedded in the rubber of the cushion so formed, at a point near the upper and outer surfaces of the same, is a spring steel wire, such as piano-wire, which extends longitudinally for the full length of the cushion. One extremity of this wire is secured at a convenient point to one end of the cushion-rail, while the other end thereof is attached, at the opposite end of the cushion-rail, to a straining-pin by means of which the wire may be stretched or strained to the desired degree of tension.

Claims.—(1.) In running-gear of motor road-vehicles and the like, road-wheels in sets of four, each set consisting of a tandem pair at each side of the vehicle, and having each wheel of each pair pivotally supported to allow the wheel independent up-and-down movement. (2.) In running-gear of the class indicated, transverse shafting having pivoted brackets or the like, for support by suitable connections at each side of the vehicle of a tandem pair of road-wheels. (3.) In running-gear of the class indicated, the combination with tandem road-wheels, of pivoted supporting members or the like, a springy or other pivoted rocker, and springs between the rocker-arm ends and supports carried by the pivoted members.
[NOTE.—Here follow fourteen other claims.]
