Abstract

254,019. Norman, J. W. March 27, 1925. Turning. - Concavo-convex articles such as wash bowls or lamp shades are cut out of a rotating block c of stone, marble or the like by means of a cutter e comprising several bowl-shaped members and mounted so as to be fed into the block c by rotation upon trunnions l. The cutter may be rotated about its central spindle f, on which the various bowl-shaped members are mounted, by means of bevel gearing o, n. The edge of each bowl-shaped member is formed with teeth or covered with an abrading substance such as carborundum.
