Patent number: 4342404Abstract: A can end conveying device for conveying ends from a first press to a second press. The conveyor has an input end and a divertor downstream therefrom. Ends are conveyed along a first track to a stacking station which feeds the ends through a first conduit in a block and then through a gate and onto the track for the second press. When the supply of ends from the first press terminates or falls below the demand of the second press, the gate is shifted and ends are fed by an operator onto a manual feeding track for the second press. When the supply of ends from the first press exceeds the demand of the second press, the divertor is activated by a sensor on the stack and diverts the ends from the first track to a second track leading to a manual bagging station. A novel gate structure is disclosed which facilitates jam free operation of the device.Type: GrantFiled: July 16, 1980Date of Patent: August 3, 1982Assignee: American Can CompanyInventor: Harry T.
