<p>341,765. Cutting wire glass. MISSISSIPI GLASS CO., 220, 5th Avenue, New York, U.S.A.-(Assignees of Aurien, G. and Gutmann, P. F.; 110, Ferry Street, St. Louis, Missouri, U.S.A.) March 5, 1930, No. 7172. Convention date, July 10, 1929. [Class 56.] A method of cutting wire sheet glass when it is made by a continuous process consists in scoring one surface of the glass in a number of closelyspaced parallel lines, breaking the glass along the lines, and then breaking the wires at the fractures. The continuous ribbon of glass, 10, Figs. 1 and 2, moves along a number of rollers 12 mounted in a bench 14, and an operator scores the glass transversely with a diamond in three parallel lines 16 about four inches apart. The glass is broken along the scored lines by a device comprising an upper roller 18 in fixed bearings, and a lower roller 20 which may be raised by a treadle from the position shown in dotted lines in Fig. 2 to that shown in full lines. After the glass is broken, the ribbon continues to move over the rollers 12 until the fracture reaches the breaking device. This comprises two rollers 24, 26 and a breaking- bar 28 arranged between them. The bar is raised by the operator when the middle fractured line is above it, and the pressure of its V-shaped edge acuses the wire embedded in the glass to break at one of the fractures.</p> |
