PNEUMATIC NUT-RUNNER WITH TORQUE INDICATOR

摘要

A pneumatically powered hand-held torque wrench having a dial gage arranged on the handel portion of the wrench to display the amount of torque exerted upon a fastener by the tool. A pointer indicates the tool maximum torque attained during tool operation, including manual torquing effort by the tool operator, which pointer maintains maximum torque read-out until the pointer is reset by the operator. A mechanical linkage arrangement transmits tool handle flexure into rotation of the dial gage to indicate maximum torque value developed upon a fastener being worked upon.
