Abrasive adjustment control for double disc grinder

Abstract

Abstract THE APPARATUS OF THIS DISCLOSURE RELATES TO DISC GRIDERS FOR GRINDING THIN WORKPIECES WHICH MUST BE HELD WITHIN CLOSE LIMITS. AS GROUND WORKPIECES EMERGE FROM THE MAACHINE, THEY ARE MEASURED BY A POST PROCESS GAGING DEVICE. WHEN A CHANGE IN SIZE OF THE WORKPIECE INDICATES THE NEED FOR ADJUSTMENT OF THE DISCS, THE GAGE MAY OPERATE A SIGNAL OR AN AUTOMATIC CORRECTING DEVICE TO MAKE THE NECESSARY CHANGE. FOR THE PURPOSE OF ILLUSTRATION, THE CORRECTING FUNCTION IS INITIATED BY MEANS OF A PUSH BUTTON. SUCCESSIVE OPERATION OF THE PUSH BUTTON IN RESPONSE TO THE SIGNAL FROM THE POST PROCESS GAGE ADVANCES ONE OF THE DISCS TOWARD THE OTHER BY A SERIES OF SINGLE INCREMENTS. AFTER A PREDETERMINED NUMBER OF SUCH INCREMENTS, A COUNTER TRANSFERS THE SUBSEQUENT SIGNAL OR PUSH BUTTON CONTACT TO EFFECT THE ADVANCE OF THE OTHER DISC. THEREAFTER, SAID OTHER DISC IS ADVANCED IN RESPONSE TO THE PUSH BUTTON UNTIL IT ENGAGES A SENSING DEVICE. THE SENSING DEVICE THEN INITIATES OPERATION OF THE FEED MECHANISM TO RETRACT THE DISC WHICH ACTUATED A SENSING DEVICE, A PREDETERMINED DISTANCE AND ADVANCES THE OTHER DISC BY THE SAME AMOUNT. THIS MOVEMENT OF THE TWO DISCS RESTORES THEM TO THE INITIAL POSITION RELATIVE TO THE GUIDE MEMBERS WHICH DIRECT THE WORKPIECES BETWEEN THE DISCS.
