Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 13th November, 1907.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 21845.—29th September, 1906.—JAMES LANGFORD, of Waihi, New Zealand, Mining Engineer. An improved amalgamating-machine for saving gold and silver.*

Claims.—(1.) An amalgamating-machine for saving gold and silver, the same consisting of a plate or plates arranged on an inclined plane or planes upon a central axis, and the surfaces of which are covered with ore-catching and retaining material, the whole being adapted to revolve by the action of a current of water in which it is placed, substantially as specified. (2.) The improved amalgamating-machine, substantially as described and explained, and as illustrated in the drawings.

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

No. 22019.—6th November, 1906.—CHENERY SUGGATE, Gas Engineer, and WILLIAM EDWARD CAYLEY-ALEXANDER, Mining Engineer, both of Auckland, New Zealand. An improved furnace for the treatment of complex or refractory ores.*

Extract from Specification.—This invention relates to an improved construction of furnace for the treatment of complex or refractory gold, silver, and other metal-bearing ores, and wherein the ore to be treated is roasted while being subjected to the action of pure water-gas in a gaseous state under pressure, the atmospheric air being excluded from the furnace during such action, the ores so treated being thereby rendered exceedingly friable, the base metals and materials contained in the ores being carried off as volatile compounds with the constituent gases of the water-gas—that is to say, equal volumes of carbon monoxide and hydrogen—or being reduced to such a condition as will permit of the valuable metal contained in the ore being readily separated from the baser metals by subsequent amalgamation or other suitable treatment, the water-gas and gaseous fuel for such process being produced in the manner described.

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

(Specification, 7s.; drawing, 7s.)

No. 22120.—27th November, 1906.—CORK ASPHALT, LIMITED, of 85 London Wall, E.C., London, and JOSEPH WILLIAM WALKER, Secretary of said Company (assignees of Charles Morland Cunynghame Hughes, of Blomfield House, London. Wall, London, Colonial Broker; Thomas Henry Quinlan, of 11 Angel Court, in the said city, Gentleman; and Robert Middleton, of Sheepscar Foundry, Leeds, York, England, Engineer). Improvements in machines for making blocks, plates, or other articles from plastic materials.

Claims.—(1.) In a machine for making blocks, plates, or other articles from plastic materials, the combination with a hopper and mixing chamber of a mould-feeding plunger, a plunger for pushing the filled moulds upon a clamp and a hydraulic press for compressing the moulded articles, a feed-table for bringing the moulds within reach of the other parts of the machine, and the reciprocating feed-plunger which causes the moulds to be successively passed from the feed-table to the operating parts of the machine, all as specified and as illustrated in the drawings. (2.) In a machine for making blocks, plates, or other articles from plastic materials, the feed-mechanism constructed and operating as shown in and described with reference to Figs. 6 to 9b. (3.) A machine for making blocks, plates, or other articles from plastic materials, constructed and operating substantially as set forth and as illustrated in the drawings.

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

No. 22222.—20th December, 1906.—UNITED SHOE MACHINERY COMPANY, of Paterson, State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of Arthur Bates and Henry Percival Gamble, of Leicester, England, Engineers). Improvements in or relating to machines for inserting fastenings.*

Claims.—(1.) In a machine for inserting fasteners, protectors, or similar articles into stock, the combination with a nail-changing device and its actuator of a work-calipering device that establishes or renders operative a connection between the changing device and the actuator, for the purpose described. (2.) In a machine for inserting fasteners, protectors, or similar articles into stock, the combination with a nail-changing device and its actuator of a work-calipering device that establishes different operative relationships between the changing device and the actuator, for the purpose described. (3.) In a machine for inserting fasteners, protectors, or similar articles into stock, an actuator that is a reciprocating machine-element (for example, 66) travelling upon and relatively to a part that is in operative connection with the work-calipering means, and that is shifted by said part in a direction transverse to that of the reciprocation to establish different operative relationships between the nail-changing device and said actuator. (4.) In a machine for inserting a plurality of different fasteners or protectors, or similar articles into stock, the combination of a fastener-changing member and a member to actuate the fastener-changing member, each member having one or more knife-edges and one or more thrust-surfaces so arranged that the knife-edges co-operate to first bring the thrust-surfaces into alignment prior to any thrust being transmitted there-through. (5.) In a machine for inserting a plurality of different fasteners, or protectors, or similar articles into stock, the combination of a double-raceway and devices to shift it, of auxiliary means (for example, the arm 106, toggle 108, and spring-plunger 110) adapted to move the nail-raceway into and keep it in its extreme position whenever it is moved past the central position. (6.) In a machine for inserting a plurality of different fasteners or protectors, or similar articles into stock, the combination with an automatic fastener-changing device controlled by a work-calipering device of an adjustment (for instance, the screw-rod 56) whereby the mechanism that effects the change of fastener may be regulated. (7.) In a machine for inserting a plurality of different fasteners or protectors, or similar articles into stock, the combination of a fastener-changing member (for example, 92), a member to actuate the changing member, each having one or more knife-edges and means embracing a yielding device (such, for example, as 50, 51) actuated by a work-calipering device to bring the knife-edges into co-operative relation. (8.) In a machine for inserting a plurality of different fasteners, or protectors, or similar articles into stock, the combination of a swing frame (for example, 60) with a plunger therein so disposed in relation to a plunger-actuating element (for example, 72) that after the frame has been swung a little to one side or other of its centre position the thrust of said element tends to move the frame to its extreme position and maintain it there. (9.) In a machine for inserting fasteners, protectors, or similar articles into stock, the automatic nail-changing mechanism, substantially as illustrated in the drawings.
