No. 29111.—7th February, 1911.—MORRIS COLUMBUS WHITE and OTHO CROMWELL DURYEA, of 939 Peoples Gas Building, Chicago, United States of America, Manufacturers of briquetting-machines. Briquetting-apparatus.

Extract from Specification.—In the practical embodiment of our improvements illustrated in the drawings the briquette-moulds are incorporated in a drum containing twelve rows, or groups, of four moulds each. In each mould is a briquette forming and ejecting plunger. The drum is rotated continuously from a power-shaft, to which it is geared, and moves across the discharge-end of a suitable feed-hopper, or the like, while the plungers are retracted to cause the moulds to be filled with the material to be briquetted. As the filled moulds move downward toward the horizontal plane, their outer ends move across and are closed by a swinging platen or thrust-head, and the inner ends of the plungers register with a vibratory, plunger-engaging pusher forming part of a reciprocating ram. The ram is operatively connected with the piston of an internal-combustion power-generator. The cylinder of the power-generator communicates at its inlet-port with a pipe which supplies an explosive mixture under pressure. The inlet and exhaust valves of the said cylinder, as well as its sparking-device, are actuated from the power-shaft which rotates the drum, so that the operations of the internal-combustion power-generator are synchronized with the movement of the drum. In operation, as a row of moulds moves into register with the said platen, their plungers are acted upon by the ram mechanism, the vibratory pusher being thrust into engagement with the plungers, in the initial downward movement of the piston under the force of the compressed explosive mixture directed into the cylinder, and the movement of the ram under said pressure initially compresses the material in the moulds. The advance of the ram is effected by the piston through power-multiplying mechanism, and when the latter nears the limit of its extension the spark-plug is actuated to explode the mixture and thus complete the formation of four briquettes by the force of the explosion transmitted through the power-multiplying toggle. Shortly after the explosion the exhaust-valve of the power-generator is opened, permitting the piston to return and scavenge the cylinder and withdraw the ram out of engagement with the plungers. In the further movement of the drum the plungers are caused to be engaged by cam mechanism, which moves them outward to eject the briquettes.

No. 29120.—13th February, 1911.—CHARLES COOPER, of Mangatoki, Taranaki, New Zealand, Factory-manager. An improved silencer for steam-jets.

Extract from Specification.—According hereto, a nozzle adapted to screw upon the end of a steam-pipe has a flared mouth, and is provided with a right-angled member also having a flared mouth. A cone forming a continuation of the steam-pipe fits the nozzle and is held in position against a shoulder. The nozzle is submerged in the liquid to which the steam is admitted. The flow of steam through the cone draws the liquid through the right-angled member into the interior of the nozzle, where the steam and liquid mix together without objectionable noise.

No. 29121.—13th February, 1911.—GLOBE PRINTING COMPANY, LIMITED, a company duly incorporated under the Companies Act of New Zealand, and having its registered office in Willis Street, Wellington, New Zealand (assignees of ALEXANDER PARKER, Engineer, JOSEPH EDWIN FROST, Printer, and SAMUEL SALEK, Gentleman, all of Wellington aforesaid). A combined rotary printing, numbering, perforating, folding, and gumming machine.

Extract from Specification.—By this invention a guillotine, driven directly from printing-rollers, cuts off invoices accurately to length in a simpler and more effective manner than heretofore. The folding-apparatus, also driven directly from the printing-roller, operates synchronously with the printing of the sheets. The printing is effected upon a band of paper coiled upon a roller and fed to the machine after passing over a roller having spikes, whereby a line of perforations is made in each sheet for readily tearing off duplicate invoices. Apparatus is also provided whereby printing in two or more colours may be effected simultaneously.

No. 29124.—1st July, 1910.†—McKENZIE AND HOLLAND, LIMITED, of 58 Victoria Street, Westminster, London S.W., Railway-signal Engineers and Contractors, and WALTER ALLAN PEARCE, of 88 Croxted Road, West Dulwich, London S.E., England, Engineer. Improvements in and relating to railway-signal operating and controlling apparatus.

Extract from Specification.—The present invention consists principally in providing, in apparatus of the kind above mentioned, quick-acting circuit-controlling switch and brake mechanism combined, and so arranged that as soon as the switch mechanism is actuated or released (by actuation of the clutch mechanism in lowering or moving the signal-arm to the safety position) the brake immediately acts upon a brake-wheel or its equivalent in connection with the motor so as to promptly stop rotation of the motor and prevent its backward rotation, the arrangement being, further, such that on the return of the signal-arm to danger a moving member of the clutch mechanism acts, through suitable connections, on the combined switch and brake device so as to reset the switch in its normal position and release the brake from the motor. Further, according to this invention, a dashpot or equivalent cushioning-device is operatively connected with a moving member of the clutch mechanism so as to avoid the transmission of injurious shocks, that might be caused by movements of the signal-arm suddenly arrested, to the apparatus.

No. 29125.—14th February, 1911.—MATTHEW WHITE and JAMES HENRY WHITE, Engineers, both of 74 Inkerman Street, Luton, Bedfordshire, England. Improvements in gas-generating apparatus.

Claims.—(1.) A gas-generator plant having an annular chamber at its upper portion characterized by the fact that a water spray is arranged in said chamber to cool and free the gas from impurities, whence it is led to a scrubber having a rotatable disc provided with fins to further purify the gas. (2.) A gas-generator plant as claimed in claim (1), further characterized by the provision of an adjustable hopper whereby the suction may be regulated when dealing with fine material such as sawdust.

No. 29135.—15th February, 1911.—EDUARDO JOSE MARIA MADERO, of No. 745 calle Tucuman, Buenos Aires, Argentine Republic, South America, Mechanician. Novel rotary engine.

Claim.—A novel rotary engine substantially consisting of a circular chamber formed by two body-pieces, in the interior of which move alternately, at two diametrically opposite points, a set of plates which intercept or divide said interior, said plates, which are intermediate, being acted upon by a spring fixed to the axle, and combined with retention-stops and the obturators or plugs of the admission and exhaust ducts for motive power, said chamber forming a circular opening, which is being closed by a revolving ring, wherein is fixed the plunger which drives the same, said ring being provided with a projecting stud adapted for abutting against the end of a jointed lever and raise said ends, thus causing the disengagement of the obturating-plates in the very instant in which the plunger has passed before the corresponding plates, no matter whether the engine is running in one or the other direction, substantially as described and set forth, with reference to the drawings, and for the purpose indicated.

(Specification, 5s.)

No. 29139.—16th February, 1911.—STANDARD LIGHT COMPANY, a corporation organized under the laws of the State of Delaware, United States of America, and having offices at Wilmington, in said State, and also at Savannah, Georgia, United States of America (assignees of Herschel Merle Conner, of Chicago, Illinois, United States of America, Machinist). Improvements in vapour generators and burners.

Claims.—(1.) A kerosene-oil-gas producer, in which are combined a generator, means for supplying oil thereto, means for subjecting the oil first to a relatively moderate heat to start the vaporization and then to a much higher degree of heat to complete the same, and means for mixing such highly heated vapour with air.

[NOTE.—Here follow thirteen other claims.]
