Abstract

1346641 Shearing INTERMENUA (PTY) Ltd 19 April 1971 [20 Feb 1970 15 Sept 1970 5 Oct 1970] 22158/71 Heading B3W A reciprocating or pivoted shear comprises a fixed blade, a movable blade and a work support member located in a rest position adjacent to and along substantially the length of the shearing edge of the fixed blade in the path of the movable blade, the work support member being resiliently yieldable to resist displacement from its rest position as the movable blade is advanced past the fixed blade. As shown, Fig. 1, an upwardly bowed leaf spring 6 rests on a bar 7 and is flattened against the bar in the rest position of the support by a bracket 24 pivoted to a rod 25 adjustably mounted in a bracket 26 fixed to the shear frame 8. The bar 7 is pivoted at one end 10 to a bolt 11 adjustably and resiliently mounted on a bracket 13 fixed to the frame 8. At the other end 9 of the bar, a bolt 17 passes through a bracket 18 on the frame 8, a pivot mounting 19 on the bar and a bracket 20 on the movable blade. Adjusting nuts 22 and disc springs 21 are mounted on the bolt. As the blade 3 is lowered the end 9 of the bar 7 is depressed, allowing the spring 6 to bow upwardly and continuously support the sheet 30 in the shearing zone as shearing progresses along the sheet. In a hand-operated pivoted shear, Figs. 3 and 4 (not shown), the work support is a simple bar (40) pivoted at (41) to the shear frame at the end at which shearing is completed and supported by an adjustable spring (42) at the other end. In an alternative embodiment of hand-operated shear, Fig. 5 (not shown), the support consists of three superimposed leaf springs (47) of progressively shorter length in the direction of the shearing stroke.
