The invention comprises retrofit kits for power impact tools. The retrofit kits adapt modular control apparatuses to power impact tools that where not originally manufactured to receive a modular control apparatuses. The retrofit kits include a modular control apparatus that has a pressure regulator and a torque limiting device. A tool having such a retrofit kit incorporated with it and a method of making such a kit are also part of the invention.

An overspeed control means for pneumatic tools which includes a split ring valve slidably arranged in a circumferential groove formed in a cage member affixed to the rotor shaft of the tool. When the cage member exceeds a predetermined rotational speed, the ring valve will expand and be moved, by pressure differential acting thereupon, into engagement with a valve seat to block holes in a flow circuit for pneumatic medium being conducted to the rotor of the tool, whereby tool operation is terminated.

This invention relates to an impact wrench clutch mechanism having a single roller element extending longitudinally between a motor driven coupling and an anvil. A hammer enclosing the roller member, has a single longitudinal pocket, engaged by the roller element for transmission of rotary movement to the hammer. The anvil has cam means arranged to activate the roller element whereby anvil rotation is accomplished with or without impacting, depending upon work load resistance applied to the anvil. The cam means are arranged to provide high rate of acceleration to the hammer whereby impacting values are unexpectedly high.

A pneumatically powered hand-held torque wrench having a dial gage arranged on the handle 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.
