Abstract

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.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 162 words
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.
Claim 2
Dependent Claim 162 words
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.
Claim 3
Dependent Claim 19 words
The hanger of claim 1, wherein said arms of said movable frame and said support frame comprise elongated pins.
Claim 4
Dependent Claim 43 words
The hanger of claim 2, wherein said support frame further comprises a plurality of parallel rods having a series of said pins extending thereform, and upper and lower frame sections rigidly uniting said parallel rods of said support frame at opposite ends thereof.
Claim 5
Dependent Claim 45 words
The hanger of claim 2, wherein said movable frame further comprises a plurality of parallel rods having a series of said arms rigidly secured along the length thereof, and upper and lower crossbeams rigidly uniting said rods of said movable frame at opposite ends thereof.
Claim 6
Dependent Claim 36 words
The hanger of claim 4, wherein said rods of said movable frame extend through holes in said upper frame section of said support frame, and said upper crossbeam interlocks said movable frame with said support frame.
Claim 7
Dependent Claim 23 words
The hanger of claim 1, wherein said stop means further comprises a horizontal wall of said upper frame section of said support frame.
Claim 8
Dependent Claim 26 words
The hanger of claim 1, further comprising second stop means limiting lengthwise movement of said movable frame to an uppermost position relative to said support frame.
Claim 9
Dependent Claim 142 words
A hanger, comprising: a support frame including an elongated rod; a first movable frame mounted on said support frame, wherein said movable frame comprises an elongated rod; first means including a plurality of pins secured to said rod of said support frame for supporting a plurality of objects; second means connected to said movable frame for supporting said objects in cooperation with said first supporting means, wherein said second supporting means comprises a plurality of pins secured to said rod of said movable frame, and said pins of said first supporting means and said pins of said second supporting means are positioned in opposing pairs for supporting each one of said objects at opposite ends thereof; and means for effecting movement of said movable frame relative to said support frame and of said second supporting means relative to said first supporting means.
Claim 10
Dependent Claim 142 words
A hanger, comprising: a support frame including an elongated rod; a first movable frame mounted on said support frame, wherein said movable frame comprises an elongated rod; first means including a plurality of pins secured to said rod of said support frame for supporting a plurality of objects; second means connected to said movable frame for supporting said objects in cooperation with said first supporting means, wherein said second supporting means comprises a plurality of pins secured to said rod of said movable frame, and said pins of said first supporting means and said pins of said second supporting means are positioned in opposing pairs for supporting each one of said objects at opposite ends thereof; and means for effecting movement of said movable frame relative to said support frame and of said second supporting means relative to said first supporting means.
Claim 11
Dependent Claim 78 words
The hanger of claim 8, further comprising: a second movable frame mounted on said support frame opposite said first movable frame, wherein said pins of said first supporting means extend alternately in opposite directions from said rod of said support frame to define two sets of opposing pins with said first and second movable frames; and means for effecting movement of said second movable frame relative to said support frame substantially in unison with said first movable frame.
Claim 12
Dependent Claim 118 words
A hanger, comprising: a support frame including an elongated rod; a movable frame mounted on said support frame, wherein said movable frame comprises an elongated rod; first means including a plurality of pins secured to said rod of said support frame for supporting a plurality of objects; second means connected to said movable frame for supporting said objects in cooperation with said first supporting means; means for effecting movement of said movable frame relative to said support frame and of said second supporting means relative to said first supporting means, including a hollow tank secured to said movable frame and means for ventilating said hollow tank and preventing said hollow tank from exploding when said tank is heated.
Claim 13
Dependent Claim 118 words
A hanger, comprising: a support frame including an elongated rod; a movable frame mounted on said support frame, wherein said movable frame comprises an elongated rod; first means including a plurality of pins secured to said rod of said support frame for supporting a plurality of objects; second means connected to said movable frame for supporting said objects in cooperation with said first supporting means; means for effecting movement of said movable frame relative to said support frame and of said second supporting means relative to said first supporting means, including a hollow tank secured to said movable frame and means for ventilating said hollow tank and preventing said hollow tank from exploding when said tank is heated.
