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. Only the patent drawing is available. This patent is in the database for reference only.
“For an improvement in the art of Fulling and Felting Cloth; John D. Lounsbury, John Arnold, John A. M'Lean, and George G. Bishop, Norwalk, Fairfield County, Connecticut, July 15.
The patentees use their machinery either for fulling, or felting, but consider it as peculiarly applicable to cloth made without spinning or weaving, with the wool delivered from the carding machine.
A large drum, or cylinder, the periphery of which is formed of slats, is to receive the cloth. This cylinder turns upon gudgeons, the lower side of it dipping into a trough lined with lead, and containing an acidulated liquid, within which the cylinder is to be made to vibrate backwards and forwards. A furnace, or heater, is attached to the trough, to give to the liquor the degree of heat which may be desired. This constitutes the first operation.
A second machine, consisting of several pair of wooden rollers, standing over a trough, is next used. The rollers must be of sufficient length to allow cloth of the width to be felted, to pass between them, which it is to do repeatedly. They may be plain or fluted, and are to be pressed together by weights and levers, “this operation hardens the texture, evens the fibres, and smooths the surface of the web.
The first machine is not claimed as a new invention, it having been used on a smaller scale for washing; but its application in its enlarged form, for the fulling of cloth, is claimed. The attaching a heater to the trough, and the alternate motion given to the cylinder, are also claimed.
The principle of the rollers in the second machine is not claimed, they having been used for other purposes; but the present application, and the connecting a trough with them, are considered as new, and claimed accordingly.
It is an error to suppose that machines similar to the one first described, have not been made of a very large size. Dash wheels for washing or rinsing cloths, &c. are well known in bleach grounds, and other establishments where cloth requires this operation; they are similar in form to that now spoken of, and of very large dimensions.”
