A material separating apparatus comprising:
- a frame having a front wall, left wall, and a right wall,
- wherein said front wall has two sides and four edges, said sides being an inside side and an outside side, the edges being a top, left, right and bottom,
- wherein said left and right walls each have two sides and four edges, said sides being an inside side and an outside side, the edges being a top, a front, a back, and bottom edge,
- wherein said left wall front edge is attached to said front wall left edge and said right wall front edge is attached to said front wall right edge, said frame having an approximately rectangular shape with the front, left and right walls forming three sides of said shape,
- wherein said inside walls of said front, left and right wall face inside the rectangular shape,
- a right back support column having an upper and lower end said upper end rising vertically from the back top edge of the right wall,
- a left back support column having an upper and lower end said upper end rising vertically from the back top edge of the left wall,
- an upper cross beam with a right end and a left end, said left end of the upper cross beam attached to the upper end of said left back support column, said right end of the upper cross beam attached to the upper end of said right back support column, wherein said upper cross beam is approximately horizontal to said frame,
- a lower cross beam with a right end and a left end, said left end of the lower cross beam supported and attached to the top front edge of said left wall, said right end of the lower cross beam supported and attached to the top front edge of said right wall,
- said upper and lower cross beams being approximately parallel to each other with the upper cross beam being higher with respect to the lower cross beam and toward the back end of said frame,
- two or more fixed bars, said fixed bars having an upper and lower end,
- wherein said upper end of the two or more fixed bar is firmly attached to said upper cross beam and said lower end of the two or more fixed bars is firmly attached to said lower cross beam,
- wherein said two or more fixed bars are attached to said upper and lower cross beams in an approximately parallel arrangement,
- one or more shift bars, said shift bars having a top and bottom side and an upper and lower end,
- wherein said upper end of said shift bars is pivotally fixed to said upper cross beam and said lower end rests upon said lower cross beam,
- wherein a first shift bar is attached to said upper cross beam with each additional lift bar after said first shift bar being arranged approximately parallel to said first shift bar,
- a riser attached to the bottom side of the one or more shift bars and said riser having an upper and lower end with said upper end attached to said one or more shift bars,
- a lift bar attached to the lower end of said one or more risers,
- means for providing an upward force to said lift bar.
