Hanger for use in electrocoating
First Claim
1. A hanger, comprising:
- an elongated support frame having a plurality of arms extending therefrom;
an elongated movable frame mounted on said support frame for lengthwise movement relative to said support frame, said movable frame having a plurality of arms extending therefrom and being positioned to allow a plurality of objects to be supported on said hanger, each of said objects being supportable by a pair of one of said arms of said support frame and one of said arms of said movable frame;
stop means for limiting movement of said movable frame to a lowermost position relative to said support frame; and
a hollow tank secured to an upper end portion of said movable frame for lifting said movable frame relative to said support frame when said hanger is lowered into a liquid bath, and tilting said objects supported on said pairs of arms, said tank having a ventilation tube for preventing said hollow tank from exploding when said tank is heated.

Abstract
The invention provides a hanger for use in electropainting which solves the problem of removing trapped air bubbles from workpieces which, due to their shape, tend to retain air when lowered into a paint bath. The hanger according to the present invention includes two frames which can slide relative to one another. Workpieces to be painted are supported between the two frames, so that movement of one frame relative to the other effectively tilts the workpieces and eliminates the trapped air while the workpieces are submerged in the paint bath. For this purpose, a flotation tank can be attached to one of the frames so that the act of lowering that hanger into the paint bath causes the desired relative movement of the two frames and tilts the workpieces.
