Abstract: An apparatus is provided for positioning a workpiece on a burn table. The apparatus has a locator assembly which is moveable between a first position at which the locator is engageable with the workpiece and a second position at which the locator assembly is spaced from the workpiece.

Abstract: An apparatus is provided for locating a work piece on a burn table. The apparatus has a locator which is moveable between a first position at which the locator is engageable with the work piece and a second position at which the locator assembly is spaced from the work piece.

Abstract: A lifting frame assembly having first and second spaced hooking members adjustably carried on a second portion of the lifting frame assembly is connectable to work tools of different sizes. The lifting frame assembly is connected to a lifting device by a lever arm which causes the lifting frame assembly to hang at an acute angle relative to a vertical plane so that the work tool may be aligned relative to a tool holder of a machine tool without interference. A first end portion of the lifting frame assembly is extensible in order to traverse the length of a ram of the machine tool and further improve alignment capabilities with the tool holder.

Abstract: A master brake die has a pair of adjustable die shoes. First and second shim packages each having a plurality of shims of a preselected width are positioned adjacent a respective die shoe and moveable therewith. A preselected number of shims from each shim package is controllably moved into an operative position between a stop surface and a respective die shoe.

Abstract: A fixture arrangement for supporting a plurality of different sizes of workpieces on a table relative to a metal working tool includes an equalizing device, a stop arrangement and a clamping device. The equalizing device positions the workpiece longitudinally on the table, the stop arrangement determines the longitudinal position of the workpiece on the table, and the clamping device secures the workpiece to the table. A guide arrangement guides movement of the equalizing device on the table along the transverse path and a latch device selectively maintains the equalizing device from guided transverse movement. The stop arrangement is connected to an elongated frame of the equalizing device, movable transversely with the equalizing device, and adjustable relative to the elongated frame in the transverse directions. The fixture arrangement is particularly suited for use on a metal working machine.

Abstract: A die set having first and second dies is provided with first and second handles for carrying the die set. The first and second handles are each pivotally connected to the second die by a pin. First and second latches maintains the first and second handles at a carry position and from inadvertent pivotal movement. Each latch is releasable to permit axial movement of the handles relative to the pins and thus free the first and second handles for pivotal movement to a position at which the handles are free from interfering with connection to a ram of a press. A support is provided for maintaining the first die at a preselected position relative to the second die and from inadvertent movement relative to the second die. A lever enables rocking of the first die relative to the second so that connection to the ram of the press is easily achieved.

Abstract: An adjustable support for a die of a press brake includes a mounting bracket which has first and second interconnected portions. A mounting device connects the first portion of the mounting bracket to the ram or bed of the press brake and maintains the second portion of the mounting bracket adjacent a bearing surface of the ram or bed of the press brake and from movement relative to the bearing surface. An adjustment device is provided for engaging the bearing surface of the die and maintaining the die from tipping movement relative to the bearing surface of the press brake during loading of the die. The adjustment device is connected to the second portion of the mounting bracket. The adjustable support is particularly suited for plate forming and bending operations.

Abstract: Automatic cutting machines carry flame cutting torches in close proximity of a work piece and can force the torch into contact with an upturned cut away piece from the work piece, causing considerable damage to the cutting apparatus. The subject apparatus provides a break away torch holder having a housing surrounding a torch tube which is mounted in an adaptor. The adaptor has a pilot that matches a pilot seat in the housing. The pilot is held in the pilot seat by resilient means that allows the torch tube to move with respect to the housing when the torch strikes an upturned cut away piece. A switch means is provided to shut the cutting machine down when the torch tube means is in the housing. Sealing means is also provided to protect the piloting apparatus and switch means from the debris of the cutting action.
