Patent number: 8333136Abstract: A food product slicer includes a carriage assembly is mounted to the base for reciprocal movement back and forth past a cutting edge of a knife. An adjustable gauge plate provides variable slice thickness for food product carried by the carriage assembly. During automatic slicing, when the gauge plate is moved from the open position to the closed position, a slicer controller automatically shuts down the carriage drive in a controlled manner that causes the carriage to stop at its most forward position.Type: GrantFiled: June 6, 2012Date of Patent: December 18, 2012Assignee: Premark FEG L.L.C.Inventors: Samuel A. Rummel, Shahram Shariff

Patent number: 8215022Abstract: A food product slicer includes a base and a knife mounted for rotation relative to the base. A slide rod extends in a direction past the knife. A carriage assembly is mounted for reciprocal movement back and forth past a cutting edge of the knife. At least one bearing arrangement connects the carriage assembly to the slide rod to facilitate the reciprocal movement of the carriage assembly. The bearing arrangement includes a lubricant reservoir. A bearing bracket holds a bearing that rides on the slide rod. The lubricant reservoir is fluidly connected to deliver lubricant to the slide rod in proximity to the bearing.Type: GrantFiled: March 2, 2007Date of Patent: July 10, 2012Assignee: Premark FEG L.L.C.Inventors: Fariborz Feizi, Shahram Shariff, Brian Stump

Patent number: 8136435Abstract: A food product slicer knife includes a circular knife body with a peripheral cutting edge. A central opening passes through the knife body and includes a pair of diametrically opposed outwardly extending slots. The knife body also includes at least one set of diametrically opposed drive pin receiving openings spaced outwardly of the central opening and circumferentially offset from the diametrically opposed outwardly extending slots. A tool assembly is adapted to facilitate knife installation and removal and holds the knife when removed from a slicer. A food product slicer includes a knife mount hub adapted to cooperate with the knife to hold the knife on the slicer during operation.Type: GrantFiled: March 6, 2007Date of Patent: March 20, 2012Assignee: Premark FEG L.L.C.Inventors: Guangshan Zhu, Shahram Shariff

Patent number: 8082830Abstract: A food product slicer includes a base and a knife mounted for rotation relative to the base. A carriage assembly is mounted to the base for reciprocal movement back and forth past a cutting edge of the knife. The carriage assembly includes a home position forward of the knife and has a tray arm removably mounted to a carriage arm. An adjustable gauge plate is mounted for movement between a closed position that prevents slicing and multiple open positions that permit slicing at respective thicknesses. An interlock arrangement prevents removal of the tray arm from the carriage arm unless the carriage assembly is in the home position and the gauge plate is in the closed position. The interlock arrangement includes a key member rotatably mounted to the tray arm. A key slot may be located on the carriage arm for receiving an end of the key member.Type: GrantFiled: March 2, 2007Date of Patent: December 27, 2011Assignee: Premark FEG L.L.C.Inventors: Samuel Rummel, Brian Stump, Shiyu Chen, Shahram Shariff
