Glass container test apparatus

Abstract

Abstract TEST APPARATUS PARTICULARLY ADAPTED TO DETERMINE THE PRESENCE OF BLEMISHES OR FLAWS OR DEFECTS IN THE SIDE WALL OF A GLASS CONTAINER, WHICH BLEMISHES ADVERSELY AFFECT THE STRENGTH OF THE SIDE WALL. THE TEST APPARATUS INCLUDES, IN PREFERRED FORM, A DRIVE WHEEL OF SUFFICIENT WIDTH TO ENGAGE THE CONTAINER''S SIDE WALL FROM SHOULDER TO HEEL AT ONE POINT ON ITS PERIPHERY, AND A YOKE HAVING AN IDLER ROLLER ON EACH ARM OF SUFFICIENT LENGTH TO ENGAGE THE SIDE WALLS FROM SHOULDER TO HEEL AT A SECOND AND A THIRD POINT ON ITS PERIPHERY, THE THREE POINTS BEING DISPOSED ABOUT THE CONTAINER''S PERIPHERY SUCH THAT THE CONTAINER MAY BE GRIPPED THEREBETWEEN DURING TESTING. FURTHER, THE TEST APPARATUS INCLUDES A DEVICE TO CONTROL THE FORCE EXERTED ON THE CONTAINER AND A DEVICE TO CONTROL THE DURATION OF CONTAINER REVOLUTION AT THE FORCE. THUS, THE APPARATUS FUNCTIONS BY CONTROLLED ROTATION OF THE GLASS CONTAINER ABOUT ITS CENTER AXIS FOR A PRESELECTED PERIOD WHILE SUBJECTING THE SIDE WALL TO A PRESELECTED AND CONSTANT EXTERNAL LOAD.
