46. DAVIS, THOMAS, Guy St. Nicholas, Warwick.
The drum part of a registered thrashing machine, worked by steam or horse, adapted to thrash all kinds of grain (leaving the straw for bottings or otherwise), with revolving drum, the circumference of which is formed of a series of flutes or concave plates, and the beaters attached to the said drum and concave fixed in the interior of the same cylinder in which the drum works. These plates have teeth or sharp-edged flutes on their faces. The said teeth are not concentric with the axis of the drum, but (regarded in the direction in which the drum revolves) the second of each set advances on the first, and the third on the second.
