Abstract
An economically and technologically improved assembly for developing kinetic energy in a rotary impact tool. There is disclosed herein a two-part, readily assembled and disassembled pin cage-coupler. One part, a cylindrical, longitudinally grooved cage, which contains a clutch mechanism, is capped at one end by a lobed end plate coupler. Since there is no physical bonding during the functional life of these parts, they may be made separately by various metal working technologies, including sintering and forging.
