Abstract: A wire coiling machine having a pair of spring coiling assemblies which are disposed in coaxial relation and include rotatable heads mounted on coaxial shafts drawn by racks connected to a pair of piston and cylinder units for rotation at different or the same speeds in the same or opposite directions to form a pair of coaxial coils on a single length of wire, the coiling assemblies being axially movable in opposed directions by cam elements and return springs.

Abstract: A spring forming machine including an inclined bed structure provided with a front side having circular mounting channels surrounded by a ring of access openings, each surrounded by screwthreaded mounting sockets or perforations, and provided with a back side on which is mounted a main drive gear accessible through the openings. The mounting sockets support a variety of tool operating units each having a drive means extending through a selected clearance opening and terminating in a planetary gear engageable with the main drive gear. The mounting channels support separately, or in conjunction with the mounting sockets, a variety of wire forming tool components which are driven by corresponding tool operating units. The main drive gear also operates a wire feeding apparatus offset laterally from the bed structure.
