Abstract
An apparatus for determining the angle and height of a rotary power saw blade by sensing the angle of the saw blade from the vertical and the sine of the angle with respect to a horizontal reference as the blade height is changed. A display unit converts the sensor output to a visual indication.
Claims3
Apparatus for displaying the height of a rotary saw blade with respect to a horizontal reference in a rotary power saw system, said system including positioning means for adjusting the height of said saw blade with respect to said horizontal reference, said saw blade being journalled in said positioning means and said positioning means being journalled for rotation so as to adjust said height of said saw blade with respect to said horizontal reference, said apparatus comprising:
- sensor means disposed on said positioning means for providing a sensor output signal proportional to the sine of the angle between said positioning means and said horizontal reference,
- a visual display, and
- electronic means for converting said sensor output signal into signals driving said visual display, said electronic means including adjusting means for adjusting a gain thereof so that said saw blade height is displayed on said visual display.
