Abstract

1278152 Flying shears IUNGERER 16 June 1970 [2 Sept 1969] 29046/70 Heading B3W Flying shear for strip metal comprises an upper and a lower blade, neither shown, a toggle lever drive for actuating the lower blade, the toggle lever including arms 2, 3 pivotally connected at a joint 4, an eccentric or crank drive 7, 8 arranged at the end remote from the joint of at least one of the arms. When both arms have a crank or eccentric drive the direction of rotation of the cranks &c. may be the same, Fig. 4, or different, Fig. 2 (neither shown). To provide for mis-cutting one of the cranks may be movable to a lower position or be angularly displaced through 90 degrees relative to the other crank. Where both cranks are rotated in the same direction they may be driven at different speeds to achieve mis-cutting.
