Abstract
A device for cutting slots of varying lengths and shapes in pavement to receive a reflector, the cutting blades for cutting the slot always being at right angles to the tangent to that portion of the surface of the pavement where the slot is being cut and means permitting the cutting blades to be maintained at an optimal rotational speed regardless of the density of the type of pavement encountered.
Claims6
A device for cutting a slot in the surface of pavement, said slot being adapted to receive a headlight reflector, comprising
- support means positioned on said pavement,
- means associated with said support means for moving said support means from place to place,
- a rotary cutting means depending from said support means and of a width adapted to cut a slot in the surface of said pavement of a size adapted to receive a headlight reflector,
- means on said support means for providing power to operate said rotary cutting means,
- means on said support means for raising and lowering said rotary cutting means,
- said rotary cutting means being supported on an axis capable of being tilted,
- two cams adapted to rotate in engagement with said pavement as said support means is moved, said cams being spaced from each other and positioned on a common shaft and attached to said axis on which said rotary cutting means are supported so that said rotary cutting means performs its cutting function while at right angles to the tangent to that portion of the surface of pavement in which said slot is to be cut and so that the length and longitudinal shape of said slot is determined by said cams.
