Patent number: 6276517Abstract: A series of regularly spaced cylindrical paddles are affixed to a steel strand cable. Each end of the cable is provided with a swaged ball shank which is pivotably received within a nut. The threaded nuts are connected by a threaded screw. The paddles are advanced on the cable through a conduit by a rotatable drive wheel. The system is thus adapted for moving ice cubes and chips. The drive wheel has eight teeth, each of which has a connector trough dimensioned to receive the connector assembly. Each tooth has a leading finger with a drive face which engages a paddle when it is received within a paddle trough defined between neighboring teeth. The drive face has a radially extending wall which engages the disk of the paddle, and a second radially extending wall spaced outwardly from the first which engages the protruding shoulder of the disk, such that the disks are always driven at two spaced locations.Type: GrantFiled: January 3, 2000Date of Patent: August 21, 2001Assignee: Protoco, IncInventors: Timothy G.

Patent number: RE35555Abstract: In an automatic loading system and method wheeled carts receive five or six layers of newspaper bundles of four to six bundles per layer. A waist-high conveyor and an inclined ramp conveyor move bundles to a roller platform of independently operated roller sections selectively halted upon receipt of a bundle. When the desired number of bundles have been delivered to the roller platform, a pusher laterally moves the bundles to a split roller platform. A second group of bundles are delivered to the roller platform and the split roller platform. The sections of the split roller platform are then abruptly pulled apart causing the bundles to drop upon a fork-like platform extending into one side of a cart receiving the bundles. The pusher is retracted to the start position and the fork-like platform is lowered to receive the next layer of bundles in a like manner.Type: GrantFiled: January 9, 1995Date of Patent: July 8, 1997Assignee: Quipp Systems, Inc.Inventors: Christer A.
