AMERICAN PATENTS. LIST OF AMERICAN PATENTS WHICH ISSUED IN OCTOBER, 1830. With Remarks and Exemplifications, by the Editor.

(Concluded from page 376 of vol. vi.] 44. For an improved Smut Machine, for hulling, smutting, and cleaning grain ; Jeremiah Cose, Sodus, Wayne county, New York, October 1.

The grain to be cleaned by this machine is, in the first instance, made to fall from the shoe of the hopper into a riddle, and thence into a smut wheel, which is a wheel of fifteen inches in diameter, and three inches deep; this wheel has an eye of six inches diameter, made like that of a mill stone. The smut wheel is furnished on the under side with a sheet iron grater, or with points of iron, and runs upon a circular bed of sheet iron of the same diameter, and perforated with small holes. The grain passes between the scouring wheel and bed, and runs over eight small screens within the curb inclosing the wheel; thence it falls by a small opening through an air channel, into the eye of the stone. In its passage it is acted upon by an air wheel, or fan, to which the requisite motion is to be given, as well as to the smut, or scouring wheel.

There is no claim to any part of the machine. 45. For an improvement in the Making of Pepper and Ink Tops; William Markland, City of New York, October 1.

This patent is taken for raising the tops of ink stands, or pepper Vol. VII.- No. 1.- JANUARY, 1831.
