Description:
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.

“This machine consists principally of four skeletons of cylinders, the axes of which stand parallel to each other, and lines uniting these would form the four angles of a rectangle. These axes are about three feet in length, and at each end have six arms extending about eight inches from the centre. A bar of iron, half an inch in diameter, extends from the end of each arm to that opposite to it, and thus is formed what we have called the skeleton of a cylinder. The two upper and the two lower pair of cylinders are placed so near to each other as not to allow the arms and rods to pass, did they not each work in the spaces between the rods, or beaters, like the teeth of cog-wheels. The whole are kept in their proper places by cog-wheels on the ends of the shafts, and they all revolve inwards. The iron bars form the beaters which are to clean and dress the hemp, or flax, which is held above, and allowed to hang down between them.”
