Abstract

430,640. Trueing valve seats. BLEY, K., 6, Harsdorferstrasse, Magdeburg, Germany. Nov. 20, 1934, No. 33391. Convention date, Dec. 29, 1933. [Class 83 (iii)] A hand-operated tool for trueing valve seats comprises a cutter 4 having one or more pairs of teeth 8, 9 constituting roughing and finishing teeth respectively arranged so that the paths of their edges cross each other in cutting so that chatter marks on the work are prevented. In one form, Figs. 1 and 2, the cutter holder 3 is slipped over a pilot stem 1, the cutter being radially adjustable and secured against a flange 11 by a plate 12 and screws 13. The depth of cut is limited by a screw 5. In a modification, Fig. 6, the cutter is not radially adjustable and is provided with two pairs of cutting teeth.
