Description: |
| "My invention consists, essentially, in an arrangement of mechanism on a swing frame in such a manner that when said frame is swung forward so as to bring its operating parts in communication with the driving machinery, the clamp heads will be moved together to hold the boards to be cut, and the latter will be moved up to the cutter; also, in the arrangement of parts for releasing the swing-frame after the barrel-head has been cut." |
