Machine for mortising and tenoning lumber
|
John McClintic |
Chambersburg, PA |
This patent, which was restored after the 1836 fire at the Patent Office, is a noteworthy early woodworking machine. Patentee McClintic was a Windsor chair-maker who was active 1807 to at least 1827. This patent was licensed to Nathan West of Washington for manufacture, and also to the US Navy (who paid McClintic $700 for the rights. It is not known who actually supplied the Navy with mortising machines, or perhaps the Navy built their own machines. |

Machine for slitting tenons and small veneers
|
John McClintic |
Chambersburg, PA |
Most of the patents prior to 1836 were lost in the December 1836 fire. Only about 2000 of the almost 10000 documents were recovered. This patent's drawing and specification are lost, which is unfortunate because this appears to be the earliest US patent for slitting (as opposed to sawing) veneers. The earlier patents 4,372 and 4,484 mention slitting wood but their titles do not mention veneers, and in the absence of other information we have to assume that they did not contemplate the slitting of veneers. |
