Abstract
377,383. Sharpening file teeth. MUNDORF, B., Radevormwald, Rhineland, Germany. June 16, 1931, No. 17512. [Classes 83 (ii) and 83 (iv).] A machine for resharpening the teeth of files has a tool mounted in a slide which moves across the file and presses successively on the back of each tooth to re-set and smooth it. The slide c, Fig. 2, reciprocated by a crank a carries a tool b which is mounted so that its pressure on a file tooth may be varied, Fig. 3. A cam bar i, moving with the slide, rocks a bent piece f carrying a hinged feed finger h, and serves to move the file forward a distance of one tooth pitch on each back stroke of the tool. The working edge of the tool is bevelled in the direction of movement and also at rightangles to this, so that the file teeth are gradually set over and given the correct backing.
