发明名称 Driver apparatus
摘要 An improved and novel lag screw driving apparatus whereby a screw along with a hanger formed thereon is threaded into a wooden ceiling member or the like from floor level. The apparatus comprises a handle having a wire magazine, a wire magazine loader mounted above the handle and through which wires have ingress to and egress from the magazine, a head or holder for an eye-screw mounted on the magazine loader, at least one pair of longitudinally-split sleeves spaced one from another and to which tubular members forming the magazine and the magazine loader are clamped. Each of the split sleeves includes a ledge from which smaller and larger bores in opposing directions extend. A clamping means across the split of each sleeve and to each side of the ledge is provided so that handle tubing and the magazine loader which are inserted into the bores of the sleeve are secured therein. Chamfers along the split are provided.
