No. 15120.—14th July, 1902.—JAMES ORR, Jun., of Waitohi, Temuka, New Zealand, Farmer. Improvements in apparatus for holding bags for filling.

Claims.—(1.) In apparatus as described, in combination, a hopper having an annular groove in which a wire cable can lie, means for actuating the cable, and springs that keep it normally free from the hopper, as and for the purposes specified. (2.) In apparatus for holding bags for filling, a hopper that is provided with an annular groove and which mounts springs that keep a wire cable normally free from said hopper, a bracket on the hopper to which one end of the cable is attached and which carries a bell-crank lever, and a link connecting the lever with the other end of the cable, the whole arranged and combined substantially as illustrated and as set forth and specified.

No. 15121.—17th July, 1902.—CHARLES EDWARD ADOLPHUS ESSE, of 40, St. Helens Road, Ormskirk, Lancaster, England, Brewer. Improvements in the pneumatic inner tubes of tires.

Claims.—(1.) An inner tube for pneumatic tires, characterized by a long length with closed ends overlapping each other, the valve being placed near one end, and the other end formed with an elastic sleeve solutioned all round the tube at one part so as to leave the extreme end free all round inside the sleeve to form a pocket for the reception of the opposite end of tube and yet permit the outer sleeve to be drawn back so as to expose the end of the tube which was previously inside the sleeve, to enable any repairs to be effected. (2.) An inner air-tube for pneumatic tires of the kind mentioned in claim 1, having the combination of a rubber sleeve at one end of tube for receiving the opposite end, the said sleeve being provided with backings of canvas with intervals between each piece so that while providing sufficient strength at the point where the sleeve is drawn over the opposite end of tube there will be enough elasticity to enable the valve to be pushed through the hole in the sleeve and also freely allow for inflation. (3.) An inner tube for pneumatic tires comprising a long length of tube with closed ends overlapping each other, a valve at one end of said tube, an elastic sleeve at the other end to form a pocket for the reception of the valve-fitted end, and a hole in the sleeve to receive the valve, said hole being so made as to enable the ends of the tube to be pulled apart somewhat when the valve has been passed through it so as to bring the lock-hole out of register with the valve. (4.) An inner tube for pneumatic tires of the kind mentioned in claim 1, the arrangement by which the outer sleeve can be pulled back clear of the end of the tube, which consists in solutioning to the end of the tube inside the sleeve a tongue-piece projecting a little beyond the end of the tube, whereby if the tongue is held firmly and the sleeve then laid hold of the sleeve can be forcibly drawn back as far as it will go, thus turning it inside out. (5.) An inner tube for pneumatic tires comprising a long length of tube with closed ends overlapping each other, a valve placed near one end, and the other end formed with an elastic sleeve to which one-half of that end of the tube is solutioned, leaving the other half as a pocket for the reception of the opposite end of tube, the other end of sleeve being made with tabs with embayments between, which facilitates the valve being slipped through a lock-hole in the sleeve and one end of the tube being placed in the pocket of the other.

No. 15122.—17th July, 1902.—HARRY BURGON, of 136, Oakbrook Road, Sheffield, York, England, Sheep-shear Manufacturer. Improvements in sheep-shears.

Claims.—(1.) Sheep-shears whereof the blades are made detachable from the bow, the blades and bow having shanks forged integrally therewith respectively and adapted a shank of the one to fit in a shank of the other and to make a longitudinally-sliding-non-torsional interlocking engagement therewith, substantially as specified. (2.) Sheep-shears whereof the blades are detachably connected to the bow by shanks on the blades slidably fitting in and making longitudinally sliding non-torsional interlocking engagement with shanks on the bow, and provided with spring latches adapted to lock the shank of the one in engagement with the shank of the other, substantially as specified. (3.) Sheep-shears whereof the blades are detachably connected to the bow by shanks on the blades slidably fitting in and making longitudinally sliding non-torsional interlocking engagement with shanks on the bow, the male shanks being longitudinally slitted and divergently formed so as to fit tightly within the female shanks or sockets by spring pressure, as described.

No. 15125.—17th July, 1902.—FERDINAND MORA CANDA, of 33, West Twenty-first Street, Manhattan, New York, United States of America, Manufacturer. Improvements in locking-devices for securing cams, pulleys, gear wheels, and other like devices.

Claims.—(1.) A wedge arranged within an eccentric recess in the cam or the like and having a groove to receive a projection upon the shaft, substantially as and for the purposes described. (2.) The combination with the aforesaid wedge of a spring or springs, substantially as and for the purposes described. (3.) A locking-device having its parts constructed, arranged, and combined to operate substantially as described with reference to the drawings for the purposes specified.

No. 15131.—18th July, 1902.—THOMAS JAMES STEELE, of Auckland, New Zealand, Gentleman. An improved method of treating clay to render it suitable for road-making and other purposes.

Claim.—The method of treating clay to render it suitable for road-making and other purposes, consisting in burning the clay by placing it in successive layers over a fire and alternately with layers of fine combustible material as each layer becomes hardened, as herein specified.

No. 15134.—16th July, 1902.—THE AUTOMATIC AERATOR PATENTS, LIMITED, of 14, Sherborne Lane, London, England (assignees of Frank George Hampson, of 34, Danvers Street, Chelsea, England, Engineer). Improvements in or relating to the aeration and bottling of liquids.

Extract from Specification.—This invention relates to the aeration, delivering quantities, and bottling of liquids, and has for its chief object to provide an apparatus in which the water to be aerated can be supplied either under pressure direct from the water-service main, or from a filter, storage-tank, or other appropriate source, gas being provided by compression from bottles or in any other convenient manner. According to this invention the apparatus comprises essentially a filling-bottle or receiver into which the liquid and gas are admitted, a reservoir or aerating-chamber into which the liquid is forced from the receiver by the gas, a delivery-vessel into which the aerated product is forced by the pressure in the aerating-chamber and from which it is delivered, preferably after reduction of the pressure, or a bottling attachment, and suitable valves and valve-operating mechanism. A preliminary enriching-chamber is also preferably provided, into which the liquid is admitted before entering the receiver and wherein it is enriched by the waste or excess gas discharged from the apparatus, this gas-pressure being also employed to force the water from the enriching-chamber into the receiver. An important feature of the apparatus is that the withdrawal of a quantity of aerated liquid therefrom does not materially reduce the quantity of aerated liquid in the reservoir, as the controlling-mechanism is so arranged that when a quantity of aerated liquid is withdrawn from the apparatus fresh supplies of gas and liquid are admitted thereto from separate sources to form aerated liquid replacing the portion withdrawn; provided, therefore, that the various valves are properly regulated and operated, a constant supply of aerated liquid from the apparatus can be obtained.
[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the specification is inserted instead.]
