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.
"The wool is carded upon the ordinary carding machine, but is taken off from the main cylinder by conical dofling rollers, covered with cards, there being two of these doffing rollers, one under the other, in front of the cylinder, their larger ends standing in reversed directions. Steel doffing plates remove the wool from these conical rollers, when it winds around conical formers placed ready to receive it. Against these conical formers it is pressed by a second cone, which bears up against the former, on the side opposite to the doffing comb; this pressure gives to the body sufficient solidity, to enable it to be removed from the former.
A vibrating motion is given to the carding machine for the purpose of regulating and varying the thickness of the body. To accomplish this object, the supports of the forming rollers are not attached to the carding frame, but to the floor, by a distinct frame. The claims are:
1st. The application of the two conical doffing cards, for the purpose of taking the wool from the main cylinder.
2nd. The moving, or vibrating the carding machine, for the purpose of varying the thickness of the body.”
Journal of the Franklin Institute Vol. 6, Sept. 1829 pgs. 176-177
