19,007. Barbour, T., and Montgomery, M. Sept. 3. G i l l boxes or frames; rollers and roller heads.-To prevent the accumulation of fibres, dirt, &c. in front of the usual fixed scraper 1 for the rollers 2 of preparing - machinery for flax, hemp, jute, &c., an additional scraper 7<A>, having a recriprocating motion to act as a hammer or tapper, is employed. The scraper 1 is fixed to brackets 5 carried by rods 4 working through brackets 6, and springs 3 press the scraper against the roller. The scraper 7<A> is fixed to spindles or rods 8 working through the brackets 5, and is slotted for the passage of the holding-screws 14. A pivoted forked lever 10 oscillated by a cam or tappet and engaging a stirrup connected to the scraper 7<A> serves to depress the scraper at intervals against the action of springs 9 surrounding the rods 8. The oscillating motion may be imparted to both scrapers.
