Abstract
An apparatus for use with various shearing machines for safely and efficiently positioning material to be worked. Magnets which control the material are embedded in a body made of non-magnetic material. Magnets are positioned in the forward end of the apparatus for holding the material being worked while other magnets are positioned in the body of the apparatus for adhering the apparatus to the machine table. A handle is provided for sliding the material into the proper position.
Claims8
An apparatus for use with a sheet or plate shear machine, having a table surface, for holding down material being sheared comprising;
- a. an elongated body, said body being formed from non magnetic material, said body having a flat under body surface, an upper surface and a forward and rearward end, a cleat handle affixed to said rearward end, said forward end further comprising a cutaway forming a cavity, said cavity having an under surface, said under surface being in the same plane as said under body surface, said cavity having a specific height so as to accommodate a specific thickness of material being sheared,
- b. a magnet, said magnet being embedded into and even with said under-body surface of said elongated body so as to magnetically adhere said under body surface of said elongated body to said table surface of said sheet or plate shear, and
- c. a plurality of magnets embedded into said forward end of said elongated body even with said under surface of said cavity so as to magnetically attract and hold said material being sheared.
