No. 27755.—17th May, 1910.—ROBERT McGAFFIN, of Hastings, New Zealand, Flax-miller and Contractor. Improved flax-washing machine.*

Extract from Specification.—My invention consists of traveling chain, rope, belt, or other suitable contrivance running on grooved or flat pulleys placed directly over a dry or wet scutcher consisting of one or more beating-wheels, said pulleys to be placed in one, two, or more distinct lines so as to guide and carry stripped flax back and forward many times across a wheel or wheels. The above pulleys may be ribbed or grooved to allow one, two, or more chains, ropes, or other suitable contrivance to run on them, so as to get a better grip of the stripped flax, and also to assist in separating butts from tails. Over the top of washing wheel or wheels shall be sprayers or perforated troughs to supply water to washing-wheels.

No. 27965.—24th June, 1910.—ROBERT McGAFFIN, of Hastings, Hawke’s Bay, New Zealand, Contractor. Improvements relating to flax-catchers.

Extract from Specification.—According to my invention, a tray located beneath the delivery of the stripper is carried upon the end of a lever mounted upon a rocking-shaft, the parts being so arranged that when the rocking-shaft is rocked the tray is caused to assume positions whereby the flax is guided first to one side of the conveyor-chain and then at the desired time turned over it. The rocking-shaft is operated by a lever which is engaged at intervals by one or other of a series of arms radiating from a vertical shaft. Intermittent motion is conveyed to said vertical shaft by any means usually employed in connection with flax-catching apparatus.
