“For a Thrashing Machine; Enoch A. Harman, Upper Marketfield, Bucks County, Pennsylvania, August 5.
This improvement consists of a vibrating breast, or pitch, formed on, or near, a quarter circle, to be supported by one or more springs on each side, either of wood, or steel, above or beneath the breast, or pitch, or by pullies, or weights.
We have copied the whole of the description of the above-named machine, and it will be seen that it is without any claim, which happily avoids what appears to us to be a very great difficulty, namely, the discovery of any novelty about it. There is a cylinder, with beaters, a hollow segment of a circle, borne up by springs, and between which and the beaters the grain is to pass; there are also feeding rollers, and a feeding apron, such as are to be found attached to the greater number of its predecessors, many of which ornament the model room of the patent office.”
