ABSTRACT:
An apparatus for universally supporting and positioning a rotating grinder wheel comprising a support base carrying a cage which rotates about a horizontal axis, and with a horizontally reciprocating frame mounted within the cage for rotation with the cage and reciprocating forwardly and rearwardly relative to the cage. A lever has one end universally pivotally connected to the frame, with the opposite end of the lever extending forwardly of the frame and carrying the rotating grinding wheel. A powered vertical guide means connected to the frame raises and lowers a separately powered horizontally movable guide means, which in turn is connected to the lever free end. Thus, the wheel is universally adjusted by rotating the cage, moving the frame forwardly or rearwardly within the cage, and swinging the free end of the lever arm upwardly and sideways.
