Abstract: A sheet bending brake comprising a frame having a fixed jaw and a movable jaw and an anvil member adjustably secured to the movable jaw. The fixed jaw has a clamping surface movable between workpiece clamping and non-clamping positions relative to the clamping surface of the fixed jaw. A bending member is hingedly connected to the fixed jaw. The movable jaw is releasably locked in workpiece clamping position by a structure that includes a plurality of extensible links that are pivoted at one end to the movable jaw and at the other end to a handle. By manipulating the handle the links are moved to move the movable jaw into and out of locked clamping position. Each link is axially adjustable in length to lengthen or shorten it and includes a resilient portion to accommodate manufacturing variations or tolerances in the thickness of the sheet material being bent and to facilitate locking and unlocking of the sheet material.

Abstract: A coil stand for dispensing sheet aluminum trim or the like comprising a pair of supports carried by a base, one of which is adjustable longitudinally of the base to accommodate sheet rolls of differing widths. An arcuate array of rollers is carried by each support with the rollers of the supports being in opposed coaxial pairs. A pair of low friction spring biased keeper bars are carried by the respective supports to hold a roll of sheet stock against the rollers for free rotation. A cutting bar is cantilevered from the base for selectively clamping unrolled sheet stock against a support surface and provides a cutting edge for cooperation with a utility knife or the like for manually severing a desired amount of uncoiled sheet stock.

Abstract: A louver cutter comprising a body having a pair of spaced arms, the lower arm defining a base and the upper arm overlying the base. A lower die pad is rotatably mounted on the base for rotation about a vertical axis and is lockable in any adjusted position. A lower die block is fastened to the lower die pad such that the lower die pad has a portion projecting upwardly and spaced from the lower die block. A piston is slidable for vertical movement in said upper arm and means are provided for moving the piston toward and away from the lower die block. An upper die block is mounted on the piston and has an opening into which the piston extends. A fastener holds the upper die block on the piston. The upper die block has a vertical surface and a horizontal surface engaging the vertical and horizontal surfaces of a cutter blade.
