Abstract
331,411. Hailwood, E. A. July 31, 1929. Cutting glass.-A device for cutting glass comprises a wire helix which is heated by electricity and is arranged to be brought into contact with the glass. An arrangement for cutting glass tubes, or removing the heads from blown ware, comprises a holder made in two parts H<1>, H', Fig. 1, hinged together and provided with an aperture which conforms to the surface of the article to be cut. Two heating-wires W, preferably bedded in asbestos, are mounted on the inner surface of the holder. The wires are coiled into helices, and are comparatively thin so that they become hot rapidly. A spring C draws the holders together and enables them to embrace tubes or cylinders of varying sizes. The device may also be mounted on a table and be provided with a switch operated by a pedal. In a modified construction, the heating- wire W, Fig. 3, is attached to a handle H<x> provided with a switch P<x>. In another construction, the wire extends between two terminals and the glass article is pressed against the flexible, coiled wire.
