Machine for Sharpening and Gumming Saws.
Description:
Patent for a machine that sharpens and gums saws for cotton-gins. It does so quickly and does not fatigue the operator. It automatically feeds "the saws so as to bring the teeth successively into position to be operated upon, and which will cut the teeth uniformly, thereby preserving the circular outline of the saws and preserving the teeth of a uniform length and appearance" (lines 15-20).
