Definitions

  • the invention relates to a hanger for parts to be coated under electrical influence, comprising an upwardly inclined prong projecting from a support member.
  • a plurality of prongs preferably project from the same support member.
  • hangers have been used in electro-painting baths.
  • a part to be painted and which has an aperture is slid over a prong which is chrome plate for improved electrical contact with the part.
  • the prongs are round in transverse cross-section.
  • the contact achieved with this apparatus has not always been sufficient to achieve reliable, high-quality painting.
  • a part hung on a prong especially a.light, mass-produced part, can be dislodged from its prong by the fluid forces acting on the part as the hanger is immersed. For this reason it has been the practice to wire the parts on to the prongs, which is a tedious operation.
  • the present invention is characterised in that the hanger comprises a prong which tapers from its root to its distal end and has sharp, longitudinally extending corners.
  • the hanger comprises a prong which tapers from its root to its distal end and has sharp, longitudinally extending corners.
  • the prong is a pyramidal prong.
  • the metal hanger 2 of Fig. 1 comprises a central, box- section spine 4.
  • the spine acts as a support member for prongs 6, a row of which projects from each of the four sides of the spine.
  • the hanger 2 is shown in its orientation for dipping into a colour bath, with its spine 4 vertical, and the prongs 6 constituting a generally upwardly facing array.
  • Each prong 6 is a sharp-cornered, triangular pyramid.
  • the transverse cross-section of a prong is shown as an equilateral triangle in Fig. 3a.
  • Parts to be painted which have an aperture are,slid over the prongs to positions such as that of the metal plate 8 in Fig. 1.
  • the prong 6 contacts the inner wall of the aperture 10 of the plate 8 to be painted at the three sharp corners 12 of the prong.
  • the plate may be firmly secured on the prong and a good electrical contact is then provided between the plate and the hanger 2.
  • the hanger 2 is then lowered into the colour bath.
  • the painted plate has only three tiny areas left unpainted, at the inner wall of the aperture 10.
  • Any part may be painted provided it has an aperture which is within the range of sizes of circumcircles defined by the tapering corners of the prongs.
  • the prongs 6 should be of harder material than the parts to be painted, at least at the corners 12 of the prong. This condition may be achieved in many known ways, for example, using a hanger constructed of a hard metal, surface hardening the hanger or by using a metal which shows considerable work hardening.
  • prongs 6 are shown with sharp ends 14. It may be preferred, for safety reasons, to round off the ends.
  • Figs. 3b and 3c show alternative prongs in transverse cross-section, and depict an isosceles triangle and a spherical triangle with concave sides, respectively.
  • Another alternative is a prong of star cross-section. Prongs with other than three corners may be used; the basic requirement is simply that the prongs should have fairly sharp corners.
