Description: |
| An example of this invention appeared in a Martin J. Donnelly auction (actually, it was the improved version patented in 1876 as 177,652). The inventor died in 1863, a decade before this patent was reissued. "The object of this invention is to obtain a simple and efficient machine for simultaneously boring two holes at different distances apart for dowels, designed chiefly for the use of coopers for boring the pieces of cask-heads which are connected by dowels."See also patent 132,187, which was awarded to another resident of Guilford (who had a connection to Merchant's Guilford Iron Works) and which disclaims this patent. |
