Abstract
An apparatus for cutting sheet glass which can not only cut a glass sheet into several smaller sheets of different sizes by a single operation but also can form cutting lines on several glass sheets by superposing them one over the other in sequence without dismounting the preceding sheets from the cutting apparatus after forming cutting lines thereon so as to obtain several smaller sheets of different sizes from each large glass sheet, and also a cutter which inhibits the formation of jagged irregularities on the cut faces of the smaller sheets when separated along the cutting lines.

An apparatus for cutting sheet glass comprising in combination:
- (a) a table (1) for placing a glass sheet thereon;
- (b) a first and a second carriage (4, 5) adapted to travel along rails (2, 3) normal to each other, provided on longitudinally opposite sides and transversely opposite sides of the table;
- (c) a rotatable horizontal shaft member (9, 12, 13) connected to each of said carriages, said shaft member being capable of turning at least from a first to a second position and return;
- (d) cutters (8, 10, 11) secured to said shaft members (9, 12, 13) so as to be slidable therealong, said cutters being so disposed as to engage a glass sheet for cutting when said shaft is in said first position and removed from said glass sheet when said shaft is in said second position;
- (e) a lever (14, 15, 16) coupled at one end to said shaft member;
