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 improvement consists in passing a sheet of cards transversely to the main cylinder, approximating so near a contact as to do the work of a doffer. This sheet of cards must be a continued sheet, passing the main cylinder either as a circle or a plane, with a transverse motion; and as a circular manner has been found best adapted for use, it will be particularly described. The circle upon which this sheet of cards is placed, is fixed upon a shaft which passes under the main cylinder at right angles with its shaft, and is secured by boxes and caps to the girths of the frame of the carding machine, and from two to six inches from the centre, and is from four to six feet in diameter, and is covered with cards from the periphery towards the centre from four to eight inches, according to the length of the main cylinder, with the points of the teeth outward, and so placed as to present a line of teeth entirely across the main cylinder, and revolving with a slow motion, it takes off the wool as it passes, and carries it round to the comb, which is affixed to a shaft by three arms, and is put in motion by a crank and pitman connected with a stud on the shaft, which causes it to vibrate on its points in two stands, which are bolted to the carding machine in such a manner that the comb will be in a tangent line with the inside circle of the sheet of cards; the vibrating motion of this comb (describing an arch of a circle,) takes off the bat of wool, and delivers it to the condensing machine, which condenses and conducts it to the can for subsequent operation.
These several parts mentioned above are put in motion by belts, or gearing, and from such parts of the carding machine as is most convenient.
The common cylindrical doffer, the common comb, the roller and the shell, are all rendered useless by this improvement. The transverse motion of the sheet of cards on a circle or a plane, across the main cylinder, with the manner of operating the comb, are what is claimed as new, and constitute the invention or improvement for which a patent is now prayed.”
