No. 24524.—16th June, 1908.—ISAAC DEACHMAN, of Almonte, Lanark, Ontario, Canada, Cheese-manufacturer. Improvements in milk-can hoists.

Claims.—(1.) A milk-can hoist, including an outwardly extending track, a hay-fork carrier mounted and adapted to reciprocate thereon, means for gripping a milk-can or like receptacle connected to the carrier, winding-means within the building connected to the rope of the hay-fork carrier, means for actuating said winding-means and automatically locking the carrier when it has moved to innermost position. (2.) An apparatus according to claim 1, in which the winding-means consists of a shaft having a loose pulley thereon and a clutch adapted to throw the pulley in and out of engagement, and means automatically actuated by the carrier for locking the shaft and preventing rotation thereof. (3.) The apparatus according to claim 1, in which the winding-means consists of a shaft having a loose pulley thereon, in combination with a lever, and means actuated by the tilting of the lever one way for throwing the pulley into engagement with the shaft, and means actuated by the tilting of the lever the reverse way for locking the shaft in position. (4.) The apparatus according to claim 1, in which the winding-means consists of a shaft having spaced plates thereon between which the rope is adapted to be wound, in combination with a loose pulley on the shaft, and means for throwing the pulley into engagement with the shaft and for locking the shaft. (5.) The apparatus according to claim 1, in which the tracks are pivotally supported in position adapted to swing either way. (6.) The apparatus according to claim 5, in which a slidable stop is provided on the inner end of the track, in combination with locking-means for the winding-means actuated by the movement of the stop. (7.) A milk-can hoist, including an outwardly extending track, a hay-fork carrier reciprocatively mounted thereon, winding-means for the rope of the carrier, and means for actuating, locking, and releasing the winding-means. (8.) A milk-can hoist constructed and arranged in detail as set forth in the specifications and drawings.

No. 24526.—16th June, 1908.—JOSEPH HOPKIRK, of Hawera, Taranaki, New Zealand, Engineer. Improvements in or relating to vacuum or air pumps.

Extract from Specification.—According to this invention, the valve-chamber is constructed in two compartments, divided from each other by means of an opening constituting a valve-seat that is arranged at an incline; upon the valve-seat a hinged clack-valve is placed; the two compartments of the valve-chamber are respectively in connection with the inside of the pump-cylinder and the outside thereof, the inlet valve having its compartment above the hinged valve connected with the cylinder, and the outlet valve having the compartment below the valve connected with the cylinder. A cap is screwed on to the top of the valve-chamber by removing which all the parts of the valve may be got at.

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

No. 24527.—16th June, 1908.—BERTRAM EDWARD DUNBAR KILBURN, of Chancery Lane Station Chambers, High Holborn, London, W.C., England, Engineer. Improvements in explosives.

Claims.—(1.) In an explosive, the employment of an organic substance containing tannin, such as myrobalans, as set forth. (2.) In an explosive, the employment of an organic substance, such as myrobalans, in combination with one or more oxygen-bearing salts, as set forth. (3.) In an explosive, the combination with myrobalans of perchlorate of ammonia or of perchlorate of ammonia and saltpetre in or about the proportions set forth. (4.) The described composition of matter constituting an explosive substance, as set forth.

(Specification, 2s. 6d.)

No. 24528.—16th June, 1908.—CLAUDE HOUSTON STUART, Major, and CHARLES SCOTT SNELL, Engineer, both of 25 Victoria Street, Westminster, London, England. Improvements in apparatus for compressing elastic fluids.

Claims.—(1.) A compressing apparatus comprising a pump and a hot-air motor of the type employing a displacer for transferring air alternately to externally heated and cooled parts of the cylinder, which motor is provided with a diaphragm or the like connected through a non-rigid connection with the pump, and is adapted to perform an operative stroke on the pump under vacuum only, said displacer being actuated through an elastic connection with a part of the motor subjected to the changes of pressure produced in the motor cylinder, substantially as and for the purposes described. (2.) A compressing apparatus, according to claim 1, in which one end of the motor cylinder is closed by a diaphragm, which is connected with a loaded pump element through a non-rigid connection, which includes an equalising device for the purpose specified. (3.) Compressing apparatus substantially as described with reference to the drawings.

No. 24529.—16th June, 1908.—JAMES THOMAS HUNTER, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (the nominee of Linotype and Machinery Limited, of 188-189 Fleet Street, London, England; the assignees of William James Rennie, of 156 St. Antoine Street, Montreal, Canada, Engineer). Improvements in the assemblers of typographic composing-machines.

Extract from Specification.—The invention relates to improvements in the assemblers of typographical composing-machines of the class described in the specification of Letters Patent No. 16744. The assembler E of that specification consists of three principal parts, the channel e¹, the assembler-support e², and the sliding addenda to the said channel. After a line has been assembled in the channel e¹, the assembler E is turned, as a whole, about a vertical pivot, from the assembling or line-receiving position into the line-delivering position, and back again into the line-receiving position after the line has been delivered. The assembler is locked in each of the said positions by a bell-crank lever pivoted on the assembler-support and engaged in the respective one of two notches in the vertical pivot, and unlocked by the disengagement of the lever from the respective notch. Each unlocking and the following turning is effected by hand, and the respective locking by a spring pulling on the bell-crank lever from the assembler-support. The present invention consists in (a) improved means for effecting both the above-mentioned unlockings and turnings, and (b) automatic means for preventing the assembler being turned into the line-delivering position before it has received enough line-elements—matrices, space-bars, and quads, as the case may be—to make it of justifiable length.

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

No. 24535.—17th June, 1908.—RICHARD NOBLE, of 28 Glover Street, South Melbourne, Victoria, Australia, Engineer. Improvements in and connected with concentrating tables for treating milled or crushed ores for the recovery of minerals therefrom.

Extract from Specification.—My invention consists broadly of a rectangular table the frame of which is supported on vertically adjustable bearings and provided at its head-end with an extension adapted to engage with and take the motion of an eccentric cam affixed horizontally to a vertically revolving shaft. The tail-end of the frame is provided with a centrally projecting rod which passes through a standard, and is fitted with a spring designed to exert a constant forward pressure on the said end of the table. A wide endless canvas belt passes over the top and beneath said rectangular table. Said belt is supported and adapted to run on parallel rollers carried in the said frame and arranged at each end of the said table. The reciprocatory motion given to the head of the table by the cam is equal both longitudinally and laterally, and the material fed on to the canvas belt at the head-end of the table is given practically a circular movement, whilst towards the centre of the table and owing to the diminution of the lateral movement at this point the material is given an elliptical motion. At the tail-end of the table, where there is little or no lateral movement, the material will have a longitudinally reciprocating or to-and-fro movement.

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