Abstract
Abstract A plurality of cathodes having sheets of electroplated material on opposite faces thereof are removed from a plating tank and placed on an advancing rack which delivers the cathodes seriatim to a stripping station where the sheets of deposited metal are removed and placed upon conveyors moved to spaced vertical position and advanced through a plurality of washing stations. The sheets are deposited on a horizontal conveyor and stacked vertically on a car on a weighing scale. When approximately 5 tons of sheets have been stacked on the car, they are secured in a bundle and a label with the weight printed thereon is attached thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
91 words
The method of removing and treating plated metal sheets from a cathode which includes the steps of: placing a series of cathodes having the plated sheets thereon spaced in face to face relation a predetermined distance apart on a rack, simultaneously advancing the group of cathodes in steps along said rack in an amount equal to the spacing thereof, and delivering the endmost cathode during each advancement to a supporting means of a first conveyor disposed at right angle relation to the direction of advancement of the cathode on said rack.
Claim 2
Independent Claim
91 words
The method of removing and treating plated metal sheets from a cathode which includes the steps of: placing a series of cathodes having the plated sheets thereon spaced in face to face relation a predetermined distance apart on a rack, simultaneously advancing the group of cathodes in steps along said rack in an amount equal to the spacing thereof, and delivering the endmost cathode during each advancement to a supporting means of a first conveyor disposed at right angle relation to the direction of advancement of the cathode on said rack.
Claim 3
Dependent Claim
62 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 1, including the further step of advancing the first conveyor to a stripping station where the deposited sheets are removed from the opposite faces of the cathode, and placing the sheets upon a second conveyor with the bottom portions of the sheets disposed in adjacent relation.
Claim 4
Dependent Claim
58 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 2, including the further step of removing the sheets seriatim from the second conveyor to a third conveyor located at right angle to the second conveyor to have the bottom edges of the sheets disposed on opposite sides of said third conveyor.
Claim 5
Dependent Claim
45 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 3, including the step of having the sheets raised by a fourth conveyor to a substantially vertical position from said third conveyor and advances them through a washing area.
Claim 6
Dependent Claim
77 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 4, including the steps of advancing upstanding sheets through a first washing section where heated steam is directed toward the edges thereof, to a second washing station where less contaminated water is pressurized and directed toward the edges of the sheets, and to a third station where fresh water is directed toward the edges of the sheets as they are advanced.
Claim 7
Dependent Claim
50 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 5, including the step of advancing the sheets on a fifth conveyor to a weighing area having a pair of scales with a stacking car on each scale toward which the sheets are advanced.
Claim 8
Dependent Claim
44 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 6, including the steps of upending the sheets on the cars for standing the sheets on edge thereon and incremently advancing the car as it is being weighed.
Claim 9
Dependent Claim
56 words
The method of removing and treating plated metal sheets from a cathode as recIted in claim 7, including the step after a sufficient number of the sheets have been stacked on the car by weight indication of printing a label and securing the sheets in a bundle with the label with the weight thereon applied thereto.
Claim 10
Dependent Claim
79 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 8, including the step of moving a stop element on the fifth conveyor from its stop position to permit the sheets to advance to a stop position at the end of the conveyor to have the sheets stop at the second weighing station so that the car thereon may be loaded and weighed while the sheets on the first car are being bundled.
Claim 11
Dependent Claim
63 words
The method of removing and treating plated metal sheets from a cathode as recited in claim 9, including the step of returning the unloaded car to a position on its platform scale to receive the sheets before the second car therebeyond is loaded at which time the sheets will be delivered to a stop position at a point for loading the first car.
