No. 30154.—4th September, 1911.—HARRY CREIG, of Foxton, New Zealand, Flax-miller. Improvements in flax-strippers.

Extract from Specification.—In carrying out the invention each of the chairs for carrying the beater-bar is formed with a recess in it against which the front portion of the bar will fit, and the shoe for holding the bar in position is fitted against the back of the bar and is kept in place by means of a tension-screw passing forwardly from the back of the chair. The guide-bearing for the drum-spindle is situated behind the chair-back and is adjusted in position by means of an adjusting-bolt extending from its back and passing through a lug upon the stripper-frame. The nuts on this bolt engage with this lug and so hold the bearing in position. The bearing is provided with bushes for the drum-spindle bored slightly eccentrically and positioned so as to permit of the spindle springing back from the beater-bar, but to prevent it springing forward beyond the normal.

Extract from Specification.—In my invention I use an open chute, and I arrange and operate the cut-off door or knife vertically so that should any lumps of ore or other material be in the way of the knife as it is raised it will be possible to avoid such obstructions by partly lifting and partly negotiating the same. To assist the operation of the invention I arrange a curtain or screen just above the vertically operating knife or door, by means of which the bulk flow of material may be regulated and kept of such a depth that the door, when pushed up, can force its way through the mass. Means are also provided for operating the door and for mounting the chute. (Specification, 2s. 9d.)

Extract from Specification.—According to my present invention, the green vegetable matter is planed, shaved, scraped, or stripped from the fibre by a drum turned truly and having feather-edged strips of metal or other suitable material bolted or otherwise attached diagonally around the drum in a right- and left-hand manner. The planing, shaving, scraping, or stripping blades are attached to the strips by bolts or the like. Between the blades blocks of metal are fixed to the drum, so that when drums so provided are revolved together, then the blades on one drum plane, shave, scrape, or strip the flax upon the corresponding block of the opposing drum, or the blades can be so arranged that the green vegetable can be planed, shaved, scraped, or stripped between the edges of each set of blades. Improvements are also provided in tension apparatus for the rollers and in the feeding-apparatus of a stripper. (Specification, 3s. 6d.)

(Specification, 5s. 6d.)
