Thomas McClure, ot McConnellsville, 0., has taken measures to secure a patent for improvements in the above. These are of such a nature as to prevent the grain from be ing thrown out of or beyond the machine by the force of the threshing cylinder, and to al low of the straw being discharged or drawn from beneath the curve or deflector. This latter being made of a peculiar shape to su persede the ordinary method. The inven tion likewise consists in a peculiar arrange ment of the spouts, by which the grain is perfectly separated from foreign substances.
