Abstract

428,117. Hollow cutter heads. GAIRING, E., 1629, West Lafayette Boulevard, Detroit, Michigan, U.S.A. May 14, 1934, No. 14541. [Class 83 (iii)] A hollow cutter head comprises an annular body 1 provided with a number of radial grooves 4 each having a serrated wall coacting with the serrated faces 9 of adjustable cutting blades 7 which are locked in position by wedges 16 bearing on the plane back faces 17 of the blades. The cutting edges 10 of the blades are substantially parallel to the tool axis and the outer edges 11 are inclined to conform to a bevelled screw ring 14 which screws over the body to effect radial adjustment of the blades which is indicated by gradations 14b on the ring coacting with a mark 30 on a non- rotary washer 29 backed by a nut 31. The wedges 16 are recessed to receive the heads of longitudinal bolts 21 which are moved axially to effect the clamping by nuts 24 operated by a wrench. In a modification, Fig. 4, the blades are inclined to the tool axis and the wedges are operated by screws 191. The wedges are preferably curved at 16a to prevent lodgment of chips and radial openings 1<a>, 14a, in the tool body and screw ring respectively also facilitate the escape of chips from the work.
