Process and system for electrodeposition coating
First Claim
1. A basket for containing materials to be electrodeposition coated, which comprises(a) a body including a frame and a wire netting connected to the frame to form side walls and a bottom of said body, said body having an open top,(b) a pair of first horizontal arms projecting outward from two opposed ones of said side walls of the body, respectively,(c) a pair of vertical members projecting upward from the tops of said two opposed ones of said side walls, respectively, and(d) a pair of second horizontal arms projecting outward from said vertical members, respectively.

Abstract
A relatively great number of materials such as forged or cast motor parts of relatively small sizes are loaded into a basket. The basket is suspended from a front conveyor, and is conveyed thereby to a position in front of a coating section comprising a plurality of tanks arranged in a required order and containing liquids required for the coating. After reaching the foregoing position, the basket is carried by, or suspended from, a basket carrier and is immersed in the liquids in the tanks in the order of arrangement thereof. The basket is swung in each tank several times. After being immersed in the liquids in all tanks, the basket is conveyed, by a rear conveyor, to a furnace for baking the materials coated. The basket is passed through the furnace, and then is suspended again from the front conveyor and conveyed thereby to a section where the basket is overturned to unload the materials coated and baked. Then, the basket, which is now empty, is conveyed to the initial position.

4. A process for the electrodeposition coating of materials which includes the steps of
(A) loading materials to be electrodeposition coated into a basket, (B) introducing said basket into a plurality of tanks arranged in a selected order and containing the liquids required for the electrodeposition coating of the materials, thereby immersing the materials in the liquids, and (C) swinging the basket and the materials contained therein after introducing the basket into each said tank, (D) said basket comprising (i) a box-shaped body including a frame and a wire netting of expanded metal connected to the frame to form side walls and a bottom for said body, said body having an open top, (ii) a first pair of horizontal arms projecting outwardly from two of the opposed side walls of said body, (iii) a pair of vertical members projecting upwardly from the tops of said two opposed side walls of said body, and (iv) a second pair of horizontal arms projecting outwardly from the upper portions of said pair of vertical members.

6. A system for the electrodeposition of coating materials which comprises
(A) a plurality of baskets for containing materials to be electrodeposition coated, each basket comprising (i) a box-shaped body including a frame and a wire netting of expanded metal connected to the frame to form side walls and a bottom for said body, said body having an open top, (ii) a pair of horizontal arms projecting outwardly from two of the opposed side walls of said body, (iii) a pair of vertical members projecting upwardly from the tops of said two opposed side walls, and (iv) a pair of horizontal arms projecting outwardly from the upper portions of said pair of vertical members, (B) a plurality of tanks arranged in a selected order for the electrodeposition coating of the materials contained in said baskets, (C) a furnace for baking the materials in the baskets after the materials have been coated in said tanks, and (D) a means associated with each said tank for supporting and swinging each of said baskets.
