ABSTRACT:
A machine for repetitively cutting depressions of equal desired dimensions and at equal desired spacings between them in a highway surface includes a mobile chassis movable along the highway surface and having a support frame mounted for pivotal movement about a transverse axis, a cutting head mounted to the support frame for rotation about a transverse axis at a predetermined speed to cut a depression in the highway surface, an auxiliary frame pivotally connected about an axis to the support frame, gauge wheels rotatably mounted to the auxiliary frame and supporting the auxiliary frame and the support frame therewith above the highway surface, and a cam and control mechanism drivingly interconnected to the gauge wheels to repetitively pivotally move, in response to rotation of the gauge wheels, the auxiliary and support frames about the respective axes relative to one another and thereby repetitively vertically move in a preset sequence the cutting head between a lowered cutting position and raised non-cutting position relative to the highway surface, concurrently with continuous movement of the mobile chassis on the highway surface, to repetitively cut depressions in the highway surface having the substantially equal desired dimensions at the substantially equal desired spacings.
