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.
"There is so much want of clearness in the description of this machinery, which the drawings are insufficient to remove, that we cannot attempt an analysis until we see the model, which has not yet been received at the office. Should it, when it arrives, appear to merit special notice, it shall not be neglected."
Journal of the Franklin Institute Vol. 5, Aug. 1829 pg. 116
