Abstract
Abstract The specification and drawings disclose a plating barrel assembly which comprises a barrel member mounted for rotation about its longitudinal axis. The barrel is supported from generally vertically extending hangers formed from metal reinforced plastic and are carried by a horizontally extending frame adapted to removably rest on the upper edge of the plating tank. Means are provided for rotating the barrel and the means include a shaft rotatably carried on the horizontal frame and connected through a gear train with a gear connected to an end of the drum. At least one end of the horizontal shaft extends outwardly of the frame for releasable engagement with a drive assembly. The drive assembly is mounted on one end of the plating tank and includes a first support frame mounted for vertical adjustment and including a horizontally extending portion and an inclined portion. A motor is adjustably mounted on the inclined portion and is drivingly connected with a gear reducer unit carried on the horizontal portion. The gear reducer is positioned with its output shaft extending horizontally and carrying a gear adapted to releasably engage a gear on the shaft member. The entire drum assembly has a low total height so that it can be easily lifted from the plating tank.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A plating barrel assembly for finishing parts adapted for use in electroplating in combination with electrodes comprising: a barrel member mounted for rotation about is longitudinal axis; hanger members supporting said barrel and extending downwardly from a horizontally extending frame adapted to rest on a plating tank; means for rotating said barrel comprising a shaft member rotatably supported from said frame and having a first gear member carried thereon; a second gear carried from one of said hangers and engaging said first gear, said second gear including a flat side in constant direct contact with a flat surface on one of said hangers of a size at least equal to the size of the gear, a third gear connected to said drum and engaging said second gear; said shaft having at least one end extending outwardly from said first gear for engagement with drive means; and means on the ends of said frame for locating said assembly on a plating tank.
Claim 2
Dependent Claim
161 words
A plating barrel assembly for finishing parts adapted for use in electroplating in combination with electrodes comprising: a barrel member mounted for rotation about is longitudinal axis; hanger members supporting said barrel and extending downwardly from a horizontally extending frame adapted to rest on a plating tank; means for rotating said barrel comprising a shaft member rotatably supported from said frame and having a first gear member carried thereon; a second gear carried from one of said hangers and engaging said first gear, said second gear including a flat side in constant direct contact with a flat surface on one of said hangers of a size at least equal to the size of the gear, a third gear connected to said drum and engaging said second gear; said shaft having at least one end extending outwardly from said first gear for engagement with drive means; and means on the ends of said frame for locating said assembly on a plating tank.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said hanger members comprise at least one plastic bar member having a metal reinforcing rod sealed therein.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 wherein all of said gears are formed from plastic.
Claim 5
Dependent Claim
87 words
The apparatus of claim 1 including a plating tank having a drive assembly carried on one end thereof; said drive assembly including a first support frame mounted for vertical adjustment and including a horizontally extending portion and an inclined portion; a motor adjustably mounted on said inclined portion and drivingly connected with a gear reducer unit carried on said horizontal portion, said gear reducer having a horizontally extending output shaft provided with a gear adapted to engage a gear on the shaft which carries said first gear.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4 wherein the means for adjusting the drive assembly support plate comprise a threaded member extending downwardly from a peripheral flange on said tank.
Claim 7
Dependent Claim
17 words
The apparatus of claim 4 wherein said motor is adapted for adjusting movement along said inclined portion.
Claim 8
Dependent Claim
35 words
The apparatus of claim 4 including a flange extending about the upper end of said tank and wherein the gear on said gear reducer output shaft extends upwardly through an opening formed in said flange.
Claim 9
Dependent Claim
23 words
The apparatus of claim 4 including cooperating inclined surfaces on said frame and said tank for aligning said drum assembly with said tank.
Claim 10
Dependent Claim
171 words
In the combination of a foraminous hollow barrel enclosing metallic articles to be treated by fluid which penetrates said barrel from without, hanger brackets for supporting said barrel for rotation about its axis in a substantially horizontal plane, a support frame for supporting said brackets, gear and motor means for rotating said drum, and electrode means for passing electric current through said fluid, the improvement comprising: hubs extending through apertures in each end of said barrel along its axis, said hubs being rigidly fixed to said brackets, openings through said hubs, said electrode means extending through said openings, one of said openings being inclined downwardly from outside the barrel toward the inside, a cylindrical bearing disposed between each hub and the barrel to support the barrel in sliding rotary movement, said bearing being formed from a mixture of polypropylene and graphite, saId bearing including a longitudinal slit extending for its full length to allow the bearing to expand radially to relieve tension and minimize galling during rotary movement of said barrel.
Claim 11
Dependent Claim
171 words

Claim 12
Dependent Claim
20 words
The combination of claim 9 wherein the bearing is locked for rotation with said barrel while said hub remains stationary.
