75. BENNETT, HENRY, Liverpool — Manufacturer.

Model of a self-cleaning roller, for crushing clods, rolling growing crops, and freeing land infested with wire- worm. The rings, of which the roller is composed, are fastened by bolts running through bored bosses into the solid ends. The contrivance for self-cleaning is effected by having two of the holes in each alternate ring larger than the other, so as to allow half the roller parts to rise twice in the revolution, sufficiently to cut out all clods which may rise between them. The rings are also tapered from the outer to the inner edge, so that a clod, being squeezed in, will necessarily fall into the interior, and be broken.

Mill for mixing provender, and preparing manures for drill-sowing. The rollers are composed of double-toothed rings, working into each other; with strong gearing, heavy fly-wheel, with brass bushes, and hard-wood frame.

Gorse-cutting machine, with eight knives, fixed on a cylinder, which revolves in brass bearings, with fluted rising feed rollers, and case-hardened cutting plate.

Mill for kibbling or crushing beans, oats, etc., on hardwood frame, with case-hardened diagonally machine- fluted rollers, working in brass bushes. The feed apparatus is regulated by a screw from behind.

Oilcake crusher, for crushing oil or rape cake. The rollers are composed of double-toothed rings, bored out, and fitted with a key on a round shaft. It has double pickers for cleaning the rollers, and sliding bars, with regulating screw in the centre, giving a parallel motion to the roller.
