Apparatus for adjusting a shearbar relative to a cutterhead
First Claim
Patent Images
1. In machinery employing a prime mover which is coupled through a clutch to drive a rotatable member, and in which rotation of the rotatable member has to be established prior to initiating control action, the improvement comprising:
- first means for producing a first steady state electrical signal substantially free of transients to indicate rotation of the prime mover;
second means for producing a second steady state electrical signal substantially free of transients to indicate that the clutch, interposed between the prime mover and the rotatable member, is engaged to drive said rotatable member in rotation; and
third means for combining the first and second steady state signals so that rotation of the rotatable member is established when both the first and second steady state signals are present.
