Abstract

136,536. Nielsen, V. Dec. 4,1918, [Convention date]. Saws, sharpening.-Saw teeth are filed on both front and rear faces by a file reciprocating in different planes and at different inclinations on alternate strokes. The saw blade is steadied by a holder 14, Figs. 1 and 3, with an adjustable abutment 15, and is indexed by a cam-operated pawl 25 with a stroke adjustment 26. The file 1 is carried by a slide mounted on a slide-way 5 hinged at 6 to a frame pivotally connected to a rocking link 8. The height of the frame is controlled by stops 9, 11 engaging an abutment 10 and the end 12 of a cam-lever respectively. The cam shaft 31 rotates at half the speed of the crankdisk 21 that reciprocates the file, so that the frame is raised and lowered alternately between successive cutting strokes. Depth of cut is controlled at 28, and a cam on the crank-disk relieves the file during the return strokes. Figs. 4 and 5 show the two file positions, the change of inclination being controlled by the arm 29 that rests continually on the bed.
