Patent number: 7415813Abstract: A pattern former for assembling wrapped bakery products into predetermined patterns includes a vacuum turntable comprising a perforated plate which is driven by a belt extending around the periphery of the vacuum turntable and actuated by a motor. A first transfer apparatus includes a pusher plate which moves groups of wrapped bakery products onto the vacuum turntable and which retracts to facilitate the formation of a subsequent group of wrapped bakery products as a previous group is being transferred to the vacuum turntable. A second transfer apparatus includes a pusher plate which moves assembled patterns of wrapped bakery products from the vacuum turntable into bakery trays and which is retractable to facilitate the assembly of a subsequent pattern of wrapped bakery products as a previous pattern is being transferred to a bakery tray.Type: GrantFiled: September 24, 2003Date of Patent: August 26, 2008Assignee: Stewart Systems, Inc.Inventors: Leonard R. Kilby, John M. Lucido, John D. Leatherbee, James J. Diver

Patent number: 6666327Abstract: In one embodiment, a conveyor comprises identical carriages and apparatus for connecting the carriages end-to-end. The carriages each include first wheel pairs supported for a rotation about spaced apart parallel axes and a second wheel pair supported for rotation about a perpendicular axis. The first and second wheel pairs are rotatably supported by self-lubricated bearings. The connection apparatus may comprise either connection rods or a wire rope. In another embodiment, the conveyor comprises identical links each including first and second link portions. The link portions are pivotally interconnected by a first connecting pin which also supports a first pair of wheels. Adjacent links are interconnected by a second connecting pin which also supports a second wheel pair. The first and second wheel pairs are rotatably supported by self-lubricated bearings.Type: GrantFiled: December 4, 2002Date of Patent: December 23, 2003Assignee: Sig Simonazzi North America, Inc.Inventors: Leonard R.
