No. 31031.—13th March, 1912.—THOMAS BASSFORD, of 547 Collins Street, Melbourne, Victoria, Australia, Signalman. Improvements in sliding-jaw wrenches and the like.

Claims.—(1.) In a sliding-jaw wrench or the like, a toothed bar carrying a jaw or the like, in combination with a sliding sleeve also carrying a jaw or the like, and a partially retractable block having teeth normally engaged with the bar-teeth, the edge of the block on the side opposite its teeth being exposed and adapted for hand pressure or pull, as the case may be. (2.) Construction as in claim (1), and with the block kept in partially retractable position by means of a bolt or the like with a spring in recesses, as described. (3.) In a sliding-jaw wrench or the like, a sleeve with a jaw, and a shank having a slot receiving a block, the slot and block ends being shaped or arranged to prevent lateral displacement, as described, the slot enabling block teeth to engage teeth on the arm. (4.) In combination, the parts as described, with reference to Fig. 1. (Specification, 2s.)

No. 31064.—21st March, 1912.—BERTRAM GEORGE AIKEN HARKNESS, of Stratford, Taranaki, New Zealand, Engineer. Improved vacuum valve and pulsator.

Claims.—(1.) Apparatus for the purpose indicated, comprising the cylinders 1 and 2, the pistons connected by a rod, the D valve 9, means upon said rod for operating said valve, and the means for reciprocating said pistons within the cylinders, substantially as and for the purpose specified, and illustrated in the drawing. . . . (6.) In apparatus of the nature indicated, the means for instantly moving the valve 9 from a state of rest, consisting of the combination of the cylinders 1 and 2, the pistons 4 and 5, the rod connecting them, and the collars upon the rod, which are spaced apart the required distance so that at the desired moment they operate valve 9, substantially as and for the purpose specified and illustrated. (Specification, 6s.)

No. 31085.—3rd April, 1911.†—ERNEST GRAHAM GODFREE, of “Keighley,” Sandringham Road, Sandringham, near Melbourne, Victoria, Australia, Electrician. An improved automatic toll-recorder for telephone systems.

Extract from Specification.—The basic principle underlying this invention consists in placing a consequent pole electro-magnet in the circuits of telephone-exchange systems. This consequent pole electro-magnet is adapted to automatically close the circuit in which the registering-devices are operated only when the calling and answering subscribers are in communication. A second consequent pole electro-magnet is also inserted in the circuit, and operates after each toll has been recorded, and automatically opens the meter circuit. An open circuit is maintained during the use of the line, but when the calling-plug is withdrawn at the close of conversation the armature of the second consequent pole electro-magnet automatically returns to its normal position. (Specification, 15s.)

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 31138.—2nd April, 1912.—ROBERT CARHAMPTON MORGAN, Dunedin, New Zealand, Agent, and WILLIAM BENNET, of Mornington, near Dunedin aforesaid, Inventor. Improved bag and parcel carriers.

Extract from Specification.—We form wire into hooks, generally in pairs to get a firmer hold of the article to be carried, and these are placed at each end of a suitable handle for better convenience of carrying. The hooks preferably fold against the handle when not in use. (Specification, 2s.)

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 31139.—2nd April, 1912.—JOSE SANCHEZ JURAEZ, of 5th Nuevo Mexico Street, Mexico, Mexico, Merchant. Improvements in tires for wheels.

Claim.—(1.) In a tire for wheels, the combination of rectangular sections, a spiral spring placed in said sections and secured at the lower extremities in cavities in the sections, and at the upper ends in suitable cavities in the rim of the wheel, said spring having one or more springs inside it, said springs of such size that the second enters the first, and so on, so that the smallest may assist the biggest in case of need, and means for providing a partial union between sections to allow for lateral play. (Specification, 3s.)

[NOTE.—Here follows one other claim.]

No. 31176.—17th April, 1912.—GASTON JACQUIER, of No. 40 Portland House, Commissioner Street, Johannesburg, Transvaal, South Africa, Consulting Engineer. Improvement in recovering the gold and zinc contained in the solution of sulphate of zinc in the cyanide process for recovering gold from its ores, applicable also for the precipitation of other metallic salts in dissolution, and apparatus therefor.

Extract from Specification.—According to my invention, the metal-bearing solution is placed in a suitable tank or vessel containing one or more sheets of aluminium, or the sheets of aluminium may be subsequently placed or immersed in the solution, or one or more sheets of the aluminium may be placed in the vessel and additional sheets be placed in the solution after it has been introduced into the tank or vessel. I prefer to employ a large storage-tank for collecting the metallic solution to be treated, and to provide a strainer for removing any foreign matter, and for aerating said solution when it is being transferred from said storage-tank into the treatment tank or vessel. The treatment tank or vessel is preferably open at the top so as to admit of the entrance of the sun’s rays to the solution which is placed therein. To this end the removable top of the tank or vessel may be constructed of bars or as a rectangular frame, from which the sheet or sheets of aluminium will be suspended inside the tank or vessel. The solution is exposed to the sunlight for a period of approximately from one to four hours, either before or after it has been placed in the precipitating tank or vessel. In order to accelerate the precipitation of the metal the solution is preferably made lukewarm, or heated to a temperature of approximately 30 degrees centigrade. In due time, varying with the strength of the solution, and (or) the temperature thereof, the dissolved metal is precipitated by contact with the surfaces of the aluminium plates. The solution can be assayed from time to time by means of a hydrometer or litmus paper, and when it is ascertained that the solution is exhausted of the metallic oxide the sheets of aluminium are removed from the tank or vessel, and cleaned by means of brushes or the like, to remove therefrom all the precipitated metallic particles. The tank or vessel is then emptied of the barren solution, and the metallic slime or precipitate removed and dried. It can then be melted or sold in the state in which it is precipitated. (Specification, 13s. 6d.)

No. 31181.—12th June, 1911.†—ALBERT KILBORN, formerly of “Bondi,” New Street, Middle Brighton, but now of Cole Street, Elsternwick, Victoria, Australia, Engineer. A pneumatic liquid-drawing and automatic delivering apparatus.

Claims.—(1.) A pneumatic liquid-drawing and automatic delivering apparatus, comprising pneumatically operated valve mechanism to allow air to be alternately withdrawn from and admitted to two or more vessels, for the purpose specified. (2.) A pneumatic liquid-drawing and automatic delivering apparatus, comprising one or more pairs of stationary receiving-vessels connected with a vacuum-producer and with a supply-pipe, into which liquid is alternately drawn by vacuum and discharged by atmospheric pressure through the medium of suitable valve mechanism, substantially as set forth. (Specification, 7s.)

No. 31182.—18th April, 1912.—NINO MAGELSSEN, of Platougaten 9, Kristiania, Norway, Manager. Method of producing articles, and coats firmly adhering to articles, from plastic masses hardening into a fireproof, weatherproof elastic material capable of resisting the action of acids.
