Abstract: A device and method for removing a branch fitting from a tapped hole in a main water distribution pipeline under pressure includes a water-tight housing adapted to fit on to the pipeline over the fitting. A cutter is provided within the housing to sever the fitting and other devices include a tool holder for use in removing a part of the fitting left in place after severing. Thus, the fitment can be removed and replaced without closing off the water supply within the main distribution pipeline.

Abstract: A front feed system that includes powered rollers for feeding sheet metal into the front of a shear. In one embodiment, the system uses ball transfer apparatus for facilitating feeding the sheet metal at various angles to the shear blade as desired by the operator. The transfer apparatus may then be lowered to rest the oriented sheet metal on the rollers for delivery to the shear. In a second embodiment, a turntable is positioned proximate the shear to further facilitate final orientation of the sheet material to be sheared. In a third embodiment, the sheet metal is automatically forced against a squaring arm on the shear to assure cuts perpendicular to the edge of the sheet metal, whether the sheet is positioned on the ball transfer apparatus or on the rollers through inclination of portions of the conveyor and/or the ball transfer apparatus.

Abstract: An improved press brake plate lifter comprising a pneumatically operated support surface or table wherein the angle of the support surface can be accurately pre-adjusted to match the angle of the die. The pre-adjusted support surface is rotatably lifted simultaneously with the movement of the ram to preclude any back bending of the plate being formed.

Abstract: A press brake plate lifter has horizontally extending lift rails pivotally mounted to a supporting framework, for supporting and lifting sheet stock during press brake operations. The lift rail pivot axis is coextensive with the bending axis of the press brake die. The material support lift rails are horizontally adjustable to accommodate sheet stock of varying dimensions, while plate clamps mounted on the lift rails hold the sheet stock firmly during the bending operation.

Abstract: A front feed system including powered roller means for feeding sheet metal into the front of a shear. Elevatable ball transfer means are provided for facilitating setting the sheet metal at various angles to the blade as desired by the operator.
