ABSTRACT:
This invention is found in the construction or configuration of the elements in the head of a driver apparatus utilized in securing screws in wooden members and to its relationship with a wire magazine loader mounted to the driving apparatus itself. The invention comprises a head member having a top and an outer wall which encompasses a cavity that forms crossed passageways extending to the top, openings in the outer wall communicating with cavity, atmosphere and magazine loader. The first of such cavity passageways is formed by vertically-oriented walls and a bottom, for containing an eyelet screw. A bar is provided at the bottom, in alignment with the first passageway for supporting the screw eyelet to which a hanger wire is to be threaded. The second of such cavity passageways is formed crosswise of the first, and includes tapering walls which converge upwardly to the top of the head, diverging downwardly to a point on the outer wall, however, not extending to the plane of the bottom of the head, but rather terminating some distance above the disposition of the bottom. Corresponding openings between such terminations and the bottom communicate with the second passageway so that a wire can be threaded through the screw's eyelet mounted in the first passageway. The magazine loader, utilized for storing wires in the apparatus prior to their utilization as hangers, includes doorways to a chamber for ingress and egress for the wires, these doorways correspondingly communicating with the noted openings. The utilization of the head in operation of the apparatus effects a tightly wound looped arrangement of wire hanger to eyelet, eliminating any play in a loop about its eyelet, and thus along the length of the wire hanger, thereby assuring that a false-ceiling frame and its ceiling members are properly and permanently installed in its level position in view of many wire hangers being used in a single false-ceiling installation.
