Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 9th August, 1905.

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. 17906.—11th May, 1904.—JOHN WATSON, of High Street, Dunedin, New Zealand, Hotelkeeper, and WILLIAM MACKAY, of 29, Moray Place, Dunedin, aforesaid, Chemist. A chemical process for treatment of flax and such like.*

Claims.—(1.) A step in a process for treating flax and the like consisting in immersing stripped fibre in a solution in water of ammonia, sulphate of soda, carbonate of soda, and common soap in the relative proportions approximately as set forth. (2.) A process for treating flax and the like consisting in first stripping the fibre, then washing, and then immersing it in a hot solution in water of ammonia, sulphate of soda, carbonate of soda, and common soap in the relative proportions approximately as set forth; then washing the fibre first in hot and then in cold water, and finally drying it, substantially as set forth.

No. 18306.—11th August, 1904.—HILARY QUERTIER, of Wood’s Hotel, Dunedin, New Zealand, Engineer. Improvements in or relating to dredging and excavating machinery.*

Extract from Specification.—According to my present invention, the screen shute for delivering the finer material is supported near its upper end by a forked bracket pivoted in another bracket attached to the frame of the machine. The lower end of the shute is carried by a second forked bracket which fits telescopically within a tubular stalk pivoted to the machine. The axes of the shute end of the two supporting brackets lie in the same vertical line. A pulley is mounted upon the upper forked bracket, and is connected by a chain or the like attached to a tube provided with an operating-wheel and bearings wherein it may be rotated. The tail-shute is supported by a forked bracket pivoted in a suitable support, and has a pulley connected by a chain or the like attached to a rod passed through the before-mentioned tube and provided with an operating-handle. By operating the tube, the first shute is rotated in either direction as desired, and by operating the rod the tail-shute is similarly rotated. Pintles in the ends of the forked brackets enable the inclination of the shutes to be adjusted. In the means for preventing the apparatus from overbalancing, I dispense with wheels, and provide bars preferably of Tee steel, extending longitudinally along the sides of the machine, and secured to brackets somewhat similar to wheel-brackets. Bars of this description will bear directly upon the sleepers, and render a longitudinal sleeper unnecessary. My present self-propelling mechanism comprises a sprocket-wheel mounted loosely upon a carrying-axle of the machine, and provided with a boss upon each side. A flanged drum is mounted upon the axle upon each side of the sprocket-wheel, and is recessed to receive a boss of the said wheel at one end, and recessed at the other end to receive a collar fixed to the axle. Spring-operated pins lock the sprocket-wheel and the collar to the drum. The sprocket-wheel is rotated by any suitable means, and rotates the drum to which it is locked. The other drum is left free to rotate by withdrawing its locking-pins against the pressure of their springs until a feather secured to the side of the pins is free to rest upon the bottom of a recess formed around the pin-hole. By turning the pins round for a short distance the pins are held out of engagement by the feather resting on the bottom of the recess. The head-line is attached to one drum and the tail-line to the other. While the line on the locked drum is being wound in, the line attached to the other drum is paid out. The sprocket-wheel of the self-propelling mechanism is preferably driven by a sprocket-chain and sprocket-pinion, which are operated by a worm-wheel secured upon the shaft of the sprocket-pinion, and a worm secured upon the lower end of the vertical propelling-shaft. The self-propelling mechanism is provided with a friction-clutch, whereby undue strain is obviated. The picks at the lower end of the ladder are mounted upon a shaft carried in arms pivoted upon the shaft of the lower tumbler, and are made to revolve in a direction opposite to that of the said tumbler, preferably by a sprocket-wheel secured upon the tumbler-shaft, another sprocket-wheel secured upon the shaft of the picks, and a crossed sprocket-chain connecting the two sprocket-wheels. The arms and the picks may be adjusted, thrown forward, or drawn backward, with a circular motion by chains wound around a spindle mounted in bearings attached to the bucket-ladder. When desired a spindle is held from revolving by a ratchet-wheel secured to the spindle and a pawl pivoted upon the ladder, thus holding the picks in position for working in front of or above the ladder.
