The chaff-cutter is a machine employed for cutting hay and straw into pieces of a given length. By this process, it is found that the dried stems of plants can be more easily consumed by cattle, and, therefore, afford more nutriment. In this class of machines, the hay, straw, or other substances to be cut, are placed in a narrow oblong trough. They are then pressed forward to two revolving cylinders, which, while they hold them with firmness, gradually carry them through. They are then acted upon by one or more knives, some- times placed upon a fly-wheel or its axle, and sometimes on another wheel, to which motion is conveyed from the fly- wheel. At each stroke of these knives, a portion of the straw or other substance is cut off of the length required, as from half an inch to an inch. The desiderata in the construc- tions of these machines, are causing the knives to make the stroke in the most efficient manner, which is done by placing them in an oblique position, causing the straw or hay to be brought forward, to be acted upon by the knives with regula- rity, and so adapting this to the several strokes of the knives, as to vary the length of the cut according to the degree of fine- ness to which it is wished to reduce the stems. Fig. The foregoing figure represents a machine formed with a re- gard to these principles. Upon the axle of the fly-wheel A.
