Abstract: 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 comprise a modular control apparatus and at least one fastener. The modular control apparatus may be specially manufactured to adapt retrofit tools or an adapter may be included in the kit. Adapters intercept the energy flow to the motor of the tool and re-channels the energy flow through a modular control apparatus, which then controls the flow of energy to the motor. The retrofit kit may include instruction sheets describing and illustrating the methods of using the retrofit kit.

Abstract: An impact tool having a control system for turning off a motor at a preselected torque level.

Abstract: The invention comprises a power impact torque tool that is torque-limited by a novel torque-timing device that controls the amount of time that the tool motor operates after the operator initiates tool operation. The invention also includes the torque-timing device itself and with other tools. The invention further includes the torque-timing device in the form of a modular, releasably-attachable, user-adjustable control apparatus for tools powered by compressable fluids. The torque-time-limiting device allows the user to adjust a needle valve that controls the filling of a reservoir which, when full, provides the pressure required for actuating a shut-off valve.

Abstract: The present invention relates generally to ratchet tools and in particular to a device to reduce spreading of the head of the ratchet tool. According to the present invention, a novel thrust washer is provided which prevents spreading apart of the head. The thrust washer is characterized by a decreased overall-diameter to edge-height ratio. The present invention also presents an alternative embodiment in which the height of the thrust washer is decreased while the height of the shank spindle is increased to prevent spreading of the head.

Abstract: This invention relates generally to an impact tool. The present invention provides a vibration isolated impact tool wherein an impact mechanism and a motor assembly are arranged into a cartridge assembly. An elastomeric member resiliently connects the cartridge assembly with a housing. The cartridge assembly is free to move axially and rotationally within the housing. The elastomeric member absorbs axial vibration and torsional vibration, reducing the vibration transmitted to an operator.
