Abstract

173,721. Hardt, J., and Sobawa, J. Aug. 9, 1921. Cutting glass.-In a device for holding pencils, brushes, glass-cutters &c. for tracing ellipses by means of a string, the ends of which are fixed in the foci, the pencil &c. is held by a set-screw 6 in a sleeve 1 or. which is mounted a roller to receive the string, and a laterally projecting arm 7 carrying a rod 9 provided with a rotatably mounted ball 11 at its end. In use, the pencil &c, is inserted in the sleeve 1 and the rod 9 is adjusted so that the ball just contacts with the surface. The string is passed round the roller 2 and lies between the roller and rod 9, so that the pencil is prevented from turning on its axis and is always kept in correct position relative to the surface.
