Abstract
343,291. Sharpening saws, milling- cutters, and like tools. COLLET & ENGELHARD WERKZEUGMASCHINFABRIK AKT.-GES., 130, Bernardstrasse, Offenbach-on-Main, and SCHARFF, W., 42, Burnitzstrasse, Frankfort-on-Main, both in Germany. Jan. 30, 1930, No. 3165. [Class 60.] A machine for grinding a multiple-toothed cutter consists of a slide 26 carrying a chuck 27 to support the cutter 28, which is indexed to present the teeth 34 in succession to a grinding-wheel 45, and which is fed axially with the slide 26 a small amount after each tooth has been ground in order to compensate for the wear of the grinding-wheel. The cutter is indexed, and the grinding-wheel is reciprocated along the teeth by a crank-disc 1 carrying pins 4, 5 with which engage connecting-rods 6, 7. The rod 6 is adjustably pivoted by a screw 10 and nut 11 to a lever 8, which is coupled by a rod 15 to a friction clutch 17 acting on a friction plate 18 with a pressure adjustable by an adjustable spring 20 on a rod 21. The plate drives, through gearing 24, 25, 29, 30, the chuck 27, and the cutter teeth are positioned for grinding by a spring-pressed pawl 32 and a stop 31. The feed of the cutter at each indexing movement is produced by a cam 19, on the shaft of the clutch, and ratchet and pawl gearing 48, 49 acting to drive a screwed spindle 50. The grinding-wheel is carried by a slide 43, which is moved by a lever 37 arranged similarly to the lever 8 and moved by the rod 7. The pawl 32 may be replaced by a pawl carried on a spindle acted upon by a spring mounted in a bearing on the carriage 26. The machine is shown as for grinding a cutter with the operative faces on the end of the cutter; for grinding circumferential cutters, the table 26 is turned through 90‹.
