Claim 4

A can crusher comprising: a pair of wheels with at least one wheel having a resilient tire, frame means for holding said wheels on axles in vertical orientation in abutting alignment for rotational contact, means for rotating at least one of said wheels, first chute means for directing cans to be crushed into the intersecting contact of said wheels, second chute means below said wheels for receiving the crushed cans, a discharge tube in communication with said second chute for discharging crushed cans, air passage means below and communicating with said second chute means for receiving said cans and carrying said cans to and through said discharge tube, means for supplying air under pressure to said air passage means, said one of said wheels being non-resilient, and said non-resilient wheel having cross bar means on its outer surface for contacting and driving the resilient tire of the other wheel.

Claim 5

A can crusher comprising: a pair of wheels with at least one wheel having a resilient tire, frame means for holding said wheels on axles in vertical orientation in abutting alignment for rotational contact, means for rotating at least one of said wheels, first chute means for directing cans to be crushed into the intersecting contact of said wheels, second chute means below said wheels for receiving the crushed cans, a discharge tube in communication with said second chute for discharging crushed cans, air passage means below and communicating with said second chute means for receiving said cans and carrying said cans to and through said discharge tube, means for supplying air under pressure to said air passage means, said second chute means and said air passage means intersecting in a mixing chamber, said mixing chamber having a projecting baffle that projects into said second chute means and into air passage means, restricting each of the respective passages.

Claim 6

A can crusher comprising: a pair of wheels with at least one wheel having a resilient tire, frame means for holding said wheels on axles in vertical orientation in abutting alignment for rotational contact, means for rotating at least one of said wheels, first chute means for directing cans to be crushed into the intersecting contact of said wheels, second chute means below said wheels for receiving the crushed cans, a discharge tube in communication with said second chute for discharging crushed cans, air passage means below and communicating with said second chute means for receiving said cans and carrying said cans to and through said discharge tube, means for supplying air under pressure to said air passage means, said second chute means and said air passage means intersecting in a mixing chamber, said mixing chamber having a projecting baffle that projects into said second chute means and into air passage means, restricting each of the respective passages.

Claim 7

A can crusher as claimed in claim 3 wherein: said projecting baffle comprising a V-shaped member that projects from the side adjacent the source means for air to said air passage means, and the upper baffle surface projecting into said second chute means at an angle for deflecting downwardly moving cans through the mixing chamber and into said air passage in the direction of movement of the air.

Claim 8

A can crusher as claimed in claim 4 wherein: said V-shaped baffle restricting the volume of the air passage means creating a venturi that increases the velocity of the passing air at the point of receiving the crushed cans.

Claim 9

A can crusher comprising: a pair of wheels with at least one wheel having a resilient tire, frame means for holding said wheels on axles in vertical orientation in abutting alignment for rotational contact, means for rotating at least one of said wheels, first chute means for directing cans to be crushed into the intersecting contact of said wheels, second chute means below said wheels for receiving the crushed cans, a discharge tube in communication with said second chute for discharging crushed cans, air passage means below and communicating with said second chute means for receiving said cans and carrying said cans to and through said discharge tube, and means for supplying air under pressure to said air passage means. conveyor means for conveying aluminum cans, steel cans, bottles and other objects to the first chute means, the input end of said first chute means being substantially enclosed by an enclosed housing forming an upper hopper, and means for drawing air across the conveyor means and said upper hopper and across said input first chute means pulling aluminum cans from the upper discharge end of the conveyor into a position over and then into said first chute means.

Claim 10

A can crusher comprising: a pair of wheels with at least one wheel having a resilient tire, frame means for holding said wheels on axles in vertical orientation in abutting alignment for rotational contact, means for rotating at least one of said wheels, first chute means for directing cans to be crushed into the intersecting contact of said wheels, second chute means below said wheels for receiving the crushed cans, a discharge tube in communication with said second chute for discharging crushed cans, air passage means below and communicating with said second chute means for receiving said cans and carrying said cans to and through said discharge tube, and means for supplying air under pressure to said air passage means. conveyor means for conveying aluminum cans, steel cans, bottles and other objects to the first chute means, the input end of said first chute means being substantially enclosed by an enclosed housing forming an upper hopper, and means for drawing air across the conveyor means and said upper hopper and across said input first chute means pulling aluminum cans from the upper discharge end of the conveyor into a position over and then into said first chute means.

Claim 11

A can crusher as claimed in claim 6 including: receptacle means positioned under the upper end of the conveyor wherein bottles, being heavier than aluminum cans, fall short of the chute means and enter a bottle chute that directs the bottles into a separate container.

Claim 12

A can crusher as claimed in claim 7 in which: said conveyor means comprising a continuous belt that is rotated around an upper magnetic drum, and said magnetic drum adhering to steel cans pulling the steel cans around the drum where the belt separates the cans from the drum, which steel cans fall through a chute into a separate receptacle.

Claim 13

A can crusher as claimed in claim 8 including: a line extending from the drawing air side of said upper hopper to said air supply means, whereby said air supply is obtained by drawing air through said line on said upper hopper.
