Abstract

642,813. Centre punches. DUROSE, H. V. May 19, 1948, No. 13508. [Class 61(ii)] A centre punch 4 is slidably held in a supporting member 1 which is a permanent magnet. The two attracting flat surfaces 6 of the magnet forming the base 6 have a V- groove therebetween for engaging cylindrical surfaces. The punch 4 is held by circlips 5 in a circular, rectangular or triangular bore in the lug 2. In a modification, an attracting surface of the magnet is at the side of the holder, a groove being provided therein to guide the punch. In a further modification, the body is a U-shaped magnet.
