Patent number: 10555538Abstract: A scribe saw assembly is provided for a loin puller and has substantially reduced wear and increased life of the assembly components. A pinion assembly includes a double keyway and opposing cutouts on the pinion shaft, with dual needle bearings. A bevel gear assembly includes pins for holding the scribe saw blade and dual bearings on the bevel gear shaft to eliminate shaft flex and blade wear. The standard is mounted to the motor housing with load bearing pins to prevent loosening of the mounting bolts. An adjustable ski is provided on the standard to control the cutting depth of the scribe saw blade.Type: GrantFiled: July 31, 2019Date of Patent: February 11, 2020Assignee: Hall Fabrication, Inc.Inventor: David Chappell

Patent number: 10524483Abstract: A scribe saw head assembly is provided for a loin puller and has substantially reduced wear and increased life of the assembly components. A pinion assembly includes a pinion shaft and a thrust bearing. The shaft has a flange to support the thrust bearing, which is retained by a pair of retainers. The flange and thrust bearing provides constant contact between the pinion shaft and the standard of the scribe saw assembly, prevents side to side movement of the pinion shaft, and prevents longitudinal floating of the pinion shaft.Type: GrantFiled: July 5, 2017Date of Patent: January 7, 2020Assignee: Hall Fabrication, Inc.Inventor: Dave Chappell

Patent number: 10070657Abstract: A method and system for adjusting operation of a meat processing machine on the floor of a meat processing plant which is controlled by a PLC away from the machine. An operator at the meat processing machine is provided a digital display of pre-selected operating parameters related to the meat processing machine. The operator can adjust one or more of the pre-selected operation parameters on the display. The adjustments are communicated to the PLC, allowing real-time control of a remotely positioned PLC to minimize need of operator to have to physically walk between machine and the PLC in a remote room. In one form, the communications are via IP protocol between a web-server at the PLC and the portable digital display on a web-enabled tablet computer.Type: GrantFiled: July 14, 2016Date of Patent: September 11, 2018Assignee: Hall Fabrication, Inc.Inventors: Dave Chappell, Scott Bruce

Patent number: 9642376Abstract: An automated system and method is provided for separating left and right animal carcass cuts from one another. The system includes a conveyor to carry cut meat pieces along a path. A sensor generates a signal corresponding to the left or right cuts, and sends the signal to a processor or controller, which actuates a product diverter, which moves across the conveyor so as to push and remove selected meat pieces from the conveyor for further processing on a separate line. The diverters are pivotal out of the conveyor path if engaged by meat piece intended to continue along the conveyor path.Type: GrantFiled: June 6, 2016Date of Patent: May 9, 2017Assignee: Hall Fabrication, Inc.Inventors: Dave Chappell, Scott Bruce
