Description: |
| From the "Journal of the Franklin Institute": "We may remark of this, as we have repeatedly done of mortising machines, that the patent is granted for certain particular matters of arrangement not affecting the general construction of the machine. After the number of patents which have issued for such machines, it seems indeed almost impossible to discover a new species, and we look only for varieties of the old. In the present case the claims are to a 'mode of setting the chisel for various depths, and the scale in combination therewith, as described, and also the index for setting the chisel at any angle, as described.'" |
