Abstract
Cross slope sensing apparatus for directly and accurately measuring the cross slope of a surface finishing machine cutting blade regardless of the depth or angle of the cut, or the looseness of the attachment of the blade to the machine. The apparatus includes a sensor support table that rests on the upper edge of the cutting blade and linkage for maintaining the longitudinal axis of the table parallel to the longitudinal axis of the machine during selective positioning of the cutting blade. Since the table rides on the upper edge of the cutting blade while remaining forwardly oriented, the inclination of the table reflects the true cross slope of the blade and is directly measured and controlled by a sensor positioned on the table.
Claims10
Apparatus for sensing the cross slope of a surface finishing machine cutting blade which is selectively positionable about a universal drawbar pivot point and which is rotatable with respect to its supportive drawbar about a substantially vertical axis, comprising a support positionable on the upper edge of said cutting blade and having a longitudinal axis parallel to a horizontal longitudinal axis of said machine, means for automatically maintaining said support on the upper edge of said cutting blade with its longitudinal axis in said horizontal condition and parallel to the longitudinal machine axis as the cutting blade is positioned relative to said machine, and sensing means mounted on said support table for sensing the angle of said support with respect to the horizontal.
