“For a Thrashing Machine; Calvin Emmons, New York, July 27.
Between this thrashing machine and many others which have been made, there is a perfect resemblance, with the exception of the manner of fixing the beaters by hinging, which we believe to be new and this is the only part claimed by the patentee. The grain is to be laid upon a feeding apron, in the ordinary mode, and is carried forward to the beaters; of these there are to be from four to eight, furnished with rows of teeth, their length is governed by the width of the frame of the machine; their outer, or thicker edges, measure from 1½ to 2 inches, their inner edges, by which they are hinged to circular heads on the ends of the shaft may be about half an inch in thickness; they may be hinged either with metal, or leather, the teeth from half an inch to an inch and a half in length. The circular box in which the beaters revolve may have short teeth, or otherwise, as may be preferred.
The cut in the margin represents a section of the beater cylinder, with one of the beaters. The upper part, represented by a dotted line, is a circular case, or cover; the lower part, where the grain and straw pass, after being beaten, is formed of slats. The claim is to the construction and application of the revolving toothed beaters, attached to the circular heads, of wood, or iron, by means of joints, or hinges, which prevent the machine from clogging, acting, or revolving, within the concave frame, and applied to thrashing all kinds of small grain."
