Ultrasonic cleaning of grinding wheels

Claim 1

A DEVICE EFFECTIVE TO REMOVE IMPACTED MATERIAL FROM THE PERIPHERAL WORKING SURFACE OF AN ABRASIVE WHEEL DURING WORKING ROTATION THEREOF AT PRODUCTION GRINDING PERIPHERAL SPEEDS OF NOT LESS THAN 25 FEET PER SECOND WHICH INCLUDES, A CLEANING SHOE WHICH PRESENTS A CLEANING FACE SHAPED IN SUBSTANTIALLY ARCUTE CONFORMITY TO THE PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL WITH WHICH IT IS ASSOCIATED, A PAIR OF GUIDE FLANGES EXTENDING ALONG THE OPPOSITE SIDES OF SAID CLEANING FACE AND PRESENTING INNER SURFACE PORTIONS DESIGNED TO SNUGLY OVERLAP OPPOSITE SIDE FACE PORTIONS OF THE ABRASIVE WHEEL WITH MINIMAL WHEEL ROTATIVE CLEARANCE THEREBETWEEN, MEANS FOR ADJUSTABLY SUPPORTING THE SHOE CLEANING FACE IN PREDETERMINED SPACED PROXIMITY TO THE PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL TO BE CLEANED TO PROVIDE A CAVITATIONAL GAP THEREBETWEEN EXTENDING IN THE DIRECTION OF ROTATION OF THE ABRASIVE WHEEL AND DEFINED BETWEEN THE INNER SURFACES OF SAID GUIDE FLANGES, MEANS FOR VIBRATING SAID CLEANING SHOE AT ULTRASONIC FREQUENCIES IN A GENERAL RADIAL DIRECTION AND AT A STROKING AMPLITUDE WHICH IS LESS THAN ONE-HALF THE RADIAL DEPTH OF THE CAVITATIONAL GAP DEFINED BETWEEN THE SHOE CLEANING FACE AND THE ADJACENT PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL, AND MEANS FOR INJECTING A CLEANING FLUID INTO SAID CAVITATIONAL GAP IN SUFFICIENT QUANTITY AND UNDER SUFFICIENT PRESSURE TO ESTABLISH AN EFFECTIVE CAVITATING LAYER OF CLEANING FLUID IN SAID CAVITATIONAL GAP WHICH IS CONFINED TO FLOW BETWEEN SAID GUIDE FLANGES, CLEANING FACE AND THE ADJACENT PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL AND THENCE TO DISCHARGE FROM SAID CAVITATIONAL GAP DURING WORKING ROTATION OF THE ABRASIVE WHEEL IN THE DIRECTION OF ROTATION.

Claim 2

A DEVICE EFFECTIVE TO REMOVE IMPACTED MATERIAL FROM THE PERIPHERAL WORKING SURFACE OF AN ABRASIVE WHEEL DURING WORKING ROTATION THEREOF AT PRODUCTION GRINDING PERIPHERAL SPEEDS OF NOT LESS THAN 25 FEET PER SECOND WHICH INCLUDES, A CLEANING SHOE WHICH PRESENTS A CLEANING FACE SHAPED IN SUBSTANTIALLY ARCUTE CONFORMITY TO THE PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL WITH WHICH IT IS ASSOCIATED, A PAIR OF GUIDE FLANGES EXTENDING ALONG THE OPPOSITE SIDES OF SAID CLEANING FACE AND PRESENTING INNER SURFACE PORTIONS DESIGNED TO SNUGLY OVERLAP OPPOSITE SIDE FACE PORTIONS OF THE ABRASIVE WHEEL WITH MINIMAL WHEEL ROTATIVE CLEARANCE THEREBETWEEN, MEANS FOR ADJUSTABLY SUPPORTING THE SHOE CLEANING FACE IN PREDETERMINED SPACED PROXIMITY TO THE PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL TO BE CLEANED TO PROVIDE A CAVITATIONAL GAP THEREBETWEEN EXTENDING IN THE DIRECTION OF ROTATION OF THE ABRASIVE WHEEL AND DEFINED BETWEEN THE INNER SURFACES OF SAID GUIDE FLANGES, MEANS FOR VIBRATING SAID CLEANING SHOE AT ULTRASONIC FREQUENCIES IN A GENERAL RADIAL DIRECTION AND AT A STROKING AMPLITUDE WHICH IS LESS THAN ONE-HALF THE RADIAL DEPTH OF THE CAVITATIONAL GAP DEFINED BETWEEN THE SHOE CLEANING FACE AND THE ADJACENT PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL, AND MEANS FOR INJECTING A CLEANING FLUID INTO SAID CAVITATIONAL GAP IN SUFFICIENT QUANTITY AND UNDER SUFFICIENT PRESSURE TO ESTABLISH AN EFFECTIVE CAVITATING LAYER OF CLEANING FLUID IN SAID CAVITATIONAL GAP WHICH IS CONFINED TO FLOW BETWEEN SAID GUIDE FLANGES, CLEANING FACE AND THE ADJACENT PERIPHERAL WORKING SURFACE OF THE ABRASIVE WHEEL AND THENCE TO DISCHARGE FROM SAID CAVITATIONAL GAP DURING WORKING ROTATION OF THE ABRASIVE WHEEL IN THE DIRECTION OF ROTATION.
