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.
" For a Harpoon of cast-iron and wrought steel, with a wrought iron shaft; Jonathan Sizer, 2nd, New London, Connecticut, October 16.
The following is the specification:
"The head to be of cast-iron, zinc and tin, lead, or copper, so as to give the dart, or harpoon, sufficient strength. The edges, knife, or cutting part, to be either of wrought iron, or cast-iron, wrought steel, or cast steel; to be cast or rivetted in the head. The shank, or shaft, to be of wrought iron, wrought steel, or copper. The shaft, or shank, to be cast into, or firmly rivetted, on the head of the harpoon, and fixed therein strong and solid.
Of what materials our whalers will hereafter make their harpoons, we wot not, as nearly all, excepting the precious metals, are now patented. It is not the form of this harpoon that is new, but the old materials. We may expect to hear of a jubilee among the finny tribe, when they learn that they are not to be harpooned, either with iron, or steel, wrought or cast, zinc, tin, lead, or copper, excepting by permission of J. S. 2nd."
