Description: |
| According to the August 1842 Journal of the Franklin Institute, Vol VI 3rd series No. 2, page 124. "The improvement claimed is, for the addition of a ferrule with a flanch on to the roller of the log brace, which supports the log, as previously patented; which ferrule and flanch may slide on the said roller, and be set nearer to, or farther from, the line of the saw. The object of this improvement is to prevent the springing of the log—an effect which generally takes place after a slab has been cut from it." |
