  • the piercing element typically is in the form of a tapered rod, the small end of which is readily receivable within the initial opening 27 and the larger diameter of which is of substantially greater size than the opening 27.
  • the piercing element operates in conjunction with a suitable die, also conventional in itself, to effect as itpasses through the opening 27, a rearward extrusion of the sheet metal surrounding the opening 27, providing a rearwardly-extending cylindrical wall 28, as shown in FIG. 2.

  • the base members are completely separated by removal of the remaining segment of connecting metal in the corner area 37, and the individual finished base members 11 are discharged from the machine.
  • the completely formed base members 1 1, prior to assembly with hook members 10, are given a protective surface covering, as by galvanizing, cadmium plating, etc.
  • the plating serves both to improve the appearance of the element and also to protect it against oxidation.
  • the wire stock incorporated in the device of the invention may be described as being pre-plated.
  • the wire is a relatively hard steel wire surface treated prior to cutting by being electro-galvanized and polished.
  • the wire stock 40 for a typical small size peg board hook assembly may have a basicdiameter of around 0.147 inch.
  • This wire is fed into a suitable multiple stage production forming machine (in itself constituting no part of the invention) where the wire is shaped and assembled with the base member 11.
  • the wire stock is fed into the machine and, in a first forming stage, the wire stock is severed to the desired length and shaped to provide a shoulder enlargement l4 and an end extention 15.
  • the extention 15 may have an axial length of around 0.120 inch and a diameter of around 0.164 inch, and the shoulder 14 7 may have a diameter of around 0.2l0 inch.
  • the wire 40 is acte upon by appropriate dies to form a-balled enlargement 13 at the outer end extremity of the wire.
  • the formation of the bailed enlargement 13 is of particular advantage in the hook assembly of the invention, because of the pre-plated outer surfaceof the wire stock 40 is deformed to partially close over the cut outer end extremity 41 of the wire, which otherwise would expose the. bare metal of the wire stock.
  • resistance of the assembled unit to rotary displacement is particularly important for commercial acceptance.
  • certain of the commercial tests to which apertured panel hook assemblies are subjected involve bending of the wire element at right angles to the axis of its inner end extremity to provide great leverage, and then attempting to rotate the wire relative to the base element to which it is attached.
  • the hook assembly of the present invention exhibits superior anti-rotational strength when subjected to such testing procedures.
  • the design of the hook is such that it may be produced entirely by mechanical operations performed on high speed, multi-stage cutting and forming machines which are commercially available, so that there is minimum individual handling of the components.
  • the improved hook of the invention utilized post-plated base members and pre-plated hook members, such that the mechanically assembled unit incorporates the desired surface finish asit emerges from the assembly machine.
  • the base members 11 are subjected to plating or other suitable finishing operations after forming, it is possible to carry out the finishing operations at this stage with the base elements in a bulk form, without requiring individual handling, counting, etc., as is the case with pre-assembled units. This enables significant savings in labor cost to be realized.
  • the surface finishing operation is required to be performed after assembly has been completed because, heretofore, commercially acceptable units were required to be welded at the plate-to -wire joint, and the welding operation would of course damage any previously imparted finish.
  • the exceptional strength of-the joint is derived by the formation of the walled opening 29, resulting from pre-piercing of the base member to a relatively small diameter opening and subsequently enlarging the opening and extruding the material sur* rounding it in a axial direction to form an extended cylindrical sidewall 28.
  • This extended sidewall in conjunction with a shouldered enlargement formed on the wire element and bearing against one side of the base member 11, and radial deformations 43 bearing against the cylindrical wall 28 on the opposite side of the base member, provides a joint of extraordinary strength, which is not only superior to the conventional welded jointbut does not involve the significant factor of unreliability which is experienced with the welded joint.
  • the hook of the present invention provides a feature which is conventionally available only as an extra, at an additional cost.
  • the outer end portions of the hook element typically are simply cut off square.
  • a balled enlargement is desired at the end, as a safety feature or for improved appearance, it is customarily available only at a substantial upcharge of around 0.5 to 0.7 cents per unit.
  • the raw wire stock 40 is in any event travelling through a multi-stage forming machine, so that the balled enlargement 13 can be provided for virtually no additional cost, apart from the minor investment in the die in the first instance.
  • the balled enlargement 13 of the present hook assembly performs an additional function, of course, in that it closes the plated outer surface of the wire substantially over the end thereof, largely concealing the raw metal otherwise exposed by the cutting of the wire to length. This obviates the need for plating or other surface treating of the unit after assembly, resulting in major reductions in handling costs.
