Abstract
Abstract A magnetic can separator which is specifically constructed for assuring the separation of all-aluminum cans from steel and steel-aluminum cans. The separator includes a magnetic drum onto which cans to be classified are directed and there is a deflector plate spaced from the path of the drum a distance such that a can must be disposed parallel to the axis of the drum before it can pass the deflector plate, thereby assuring that any steel component of a can will be attracted to the drum and will be delivered to a receiving area in exclusion of a receiving area for all-aluminum cans.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A magnetic can separator comprising a drum having a substantially horizontal axis of rotation, said drum having a periphery and magnetic means disposed about said periphery, separate first and second receiving means disposed below said drum for receiving in sequence in the direction of drum rotation non-magnetically attractive cans and magnetically attractive cans, discharge means overlying said second receiving means for removing cans magnetically adhering to said drum, and deflector means for deflecting each can placed in said separator to a position substantially parallel with said drum axis prior to movement of the can to a position for discharging into one of said receiving means.
Claim 2
Dependent Claim
105 words
A magnetic can separator comprising a drum having a substantially horizontal axis of rotation, said drum having a periphery and magnetic means disposed about said periphery, separate first and second receiving means disposed below said drum for receiving in sequence in the direction of drum rotation non-magnetically attractive cans and magnetically attractive cans, discharge means overlying said second receiving means for removing cans magnetically adhering to said drum, and deflector means for deflecting each can placed in said separator to a position substantially parallel with said drum axis prior to movement of the can to a position for discharging into one of said receiving means.
Claim 3
Dependent Claim
23 words
The can separator of claim 1 wherein said deflector means lies at a position at least at the height of said drum axis.
Claim 4
Dependent Claim
29 words
The can separator of claim 1 wherein said deflector means lies at a position at least at the height of said drum axis and overlying said first receiving means.
Claim 5
Dependent Claim
44 words
The can separator of claim 1 wherein said deflector means is in the form of a gravity infeed chute having a terminal end disposed in spaced relation to said drum periphery a distance generally equal to but slightly greater than the intended can diameter.
Claim 6
Dependent Claim
22 words
The can separator of claim 1 wherein said discharge means lies at a position generally below the height of said drum axis.
Claim 7
Dependent Claim
14 words
The can separator of claim 1 wherein there is a separate gravity infeed chute.
Claim 8
Dependent Claim
30 words
The can separator of claim 6 wherein said separate gravity infeed chute is located on a side of a vertical plane through said drum axis remote from said deflector means.
Claim 9
Dependent Claim
23 words
The can separator of claim 6 wherein said deflector means lies at a position at least at the height of said drum axis.
Claim 10
Dependent Claim
29 words
The can separator of claim 7 wherein said deflector means lies at a position at least at the height of said drum axis and overlying said first receiving means.
