Abstract
A side cutter apparatus for an excavating machine having a plurality of spaced rotating digging wheels mounted on a common horizontal shaft, each wheel having a pair of spaced sidewalls, and having frame rails partially extending into the spaces between adjacent wheels; which includes a base plate affixed to the periphery of a cut-away section of a sidewall adjacent to the open space between the wheels; a pivotal side cutter including a back panel disposed in the cut-away section and pivotally mounted at its lower end on the base plate so as to pivot into the open space, a front panel disposed essentially parallel to the back panel and pivotally mounted at its lower end on a common axis with the back panel so as to be pivotally movable therewith, a cutting tooth affixed to the upper portion of the front panel and extending into the open space, a roller rotatably mounted on an axis perpendicular to the front panel and extending through the same into a vertical space between the panels wherein the roller is directly adjacent to the open space between the wheels; a spring for urging the side cutter into the open space; a stop for limiting the pivotal movement of the side cutter, a cam for moving the side cutter into a closed position against the action of the spring, and a track for maintaining the side cutter in the closed position during a predetermined portion of the wheel's rotation.
