A smut-machine and corn-screen combined. The objects of this machine are stated to be to produce on the surface of the wheat the utmost amount of friction that it can bear without breaking or injuring the grain; to fan it at the same time; scour off the fibrous end and all that adheres to it, and thus clean the wheat of all dirt- clods, smut, etc. The best wheat is said to be considerably improved by passing through this machine. This machine according to its size will clean ten to fifteen quarters of wheat per hour.
A model of a flour-dressing machine, with registered fan-brushes and flanges complete; also samples of brushes and fine wire-cloth used in the above.
Specimens of wove and twist wire in brass and copper, containing 500 picks or shoots in an inch, which is said to be the finest wire-cloth ever manufactured; also other specimens of very fine wove wire-cloth, and wove wire for covering kiln-heads.
