Abstract
Abstract A large cylindrical enclosure shaped to look like a huge beverage can has a recessed area in its outer wall containing an operator's panel and an opening into the interior for inserting empty recyclable beverage cans. Inside the enclosure is a conveyor for receiving the inserted cans, means for distinguishing between ferrous and non-ferrous recyclable cans, means for counting the number of ferrous and non-ferrous cans and pneumatic transporting means for carrying the cans to a mechanical crusher which compacts the cans individually and discharges them into a temporary storage area from which they are removed from time to time for recycling. The operator's panel includes manually operable buttons for initiating operation of the mechanisms in the interior of the strucutres and may also include various visual readouts as well as a dispenser for feeding out coins, printed credit slips and receipts. The machine also contains programmable electronic circuitry for providing information and controls necessary for operation of the equipment and for determining the amount of payout and other useful data and information.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
A collector for empty used recyclable metal beverage cans, comprising: a large cylindrical enclosure having an interior area; an opening into the interior area of said enclosure for inserting empty used beverage cans; conveying means in the interior area of said enclosure for receiving cans inserted through said opening, said conveying means comprising an endless belt with one end of the conveying means located to receive the inserted cans, a part of said conveying means being magnetized for magnetically holding only magnetically permeable cans firmly onto said belt; can crushing means in the interior area of said enclosure; means in the interior area of said enclosure for pneumatically transporting each of the cans from said conveying means to said can crushing means, said pneumatic transporting means including a pair of vacuum suction conduits suitably sized to carry beverage cans, one of said conduits having an open end facing and in close proximity to the magnetized part of said conveying means and the other of said conduits having an opening facing and in close proximity to a non-magnetized part of said conveying means; means for applying a vacuum to said conduits for respectively sucking up into said conduits cans which are not magnetically held onto said belt on the respective parts of said belt; and means in the interior area of said enclosure for receiving and storing crushed cans from said crushing means.
Claim 2
Dependent Claim

A collector for empty used recyclable metal beverage cans, comprising: a large cylindrical enclosure having an interior area; an opening into the interior area of said enclosure for inserting empty used beverage cans; conveying means in the interior area of said enclosure for receiving cans inserted through said opening, said conveying means comprising an endless belt with one end of the conveying means located to receive the inserted cans, a part of said conveying means being magnetized for magnetically holding only magnetically permeable cans firmly onto said belt; can crushing means in the interior area of said enclosure; means in the interior area of said enclosure for pneumatically transporting each of the cans from said conveying means to said can crushing means, said pneumatic transporting means including a pair of vacuum suction conduits suitably sized to carry beverage cans, one of said conduits having an open end facing and in close proximity to the magnetized part of said conveying means and the other of said conduits having an opening facing and in close proximity to a non-magnetized part of said conveying means; means for applying a vacuum to said conduits for respectively sucking up into said conduits cans which are not magnetically held onto said belt on the respective parts of said belt; and means in the interior area of said enclosure for receiving and storing crushed cans from said crushing means.
Claim 3
Dependent Claim
40 words
The beverage can collector as described in claim 1 further including can counting means comprising wire-wound coil means wrapped around each of said vacuum conduits for producing an electrical signal each time a can enters one of said vacuum conduits.
Claim 4
Dependent Claim
75 words
The beverage can collector as described in claim 1 wherein said pneumatic transporting means further includes: second conduit means coupled to said pair of vacuum conduits for receiving cans from said pair of vacuum conduits; third conduit means coupled between said second conduit means and said can crushing means; and means for applying pressurized air to said third conduit means for transporting the cans received from said second conduit means to said can crushing means.
Claim 5
Dependent Claim
177 words
A collector for use in recycling used empty metal beverage cans, comprising: a large vertically oriented cylindrical enclosure closed at its top and having an interior area; an elevated floor within the interior area of said enclosure separating the interior area of said enclosure into a lower and an upper chamber; an opening into the lower chamber of said enclosure for inserting empty metal beverage cans one at a time; conveying means in the lower chamber of said enclosure for receiving cans inserted through said opening; vacuum conduit means in the lower chamber of said enclosure for sucking up cans from said conveying means; can crushing means located at the top of the upper chamber of said enclosure; can counting means including a wire wound coil means wrapped around said vacuum conduit means for producing an electrical signal for each can which passes through said coil means; and pressurized air conduit means coupled to said vacuum conduit means for pneumatically transporting cans received from said vacuum conduit means through said elevated floor to said can crushing means.
