Description: |
| Abstract:
A principal object of the invention is to provide a novel and improved torque measuring device which is useful for testing, checking, or calibrating the dynamic torque of screwdrivers, nutsetters, and similar tools, both hand and power operated, as well as fastenings made thereby. Such tools may be divided into two general classes, those of the class having a positive clutch drive, i.e., are so constructed that torque may be applied to ,the workpiece up to the limit of capacity of the tool. Tools of the other class have an adjustable clutch arrangement which allows the tool to be preset to the torque requirements of a particular job, so that the tool "breaks" or its clutch slips when the desired tension has been reached. These settings are, however, subject to wear and/or change, so that there is also a need to be able to regularly check the torque settings of such tools. |
