Patent number: 7861751Abstract: A wood product assembly includes a cutter subassembly and a skewing assembly. A cutter positioning body is movable by a slewing assembly along a slewing axis. A spindle housing is mounted to the cutter positioning body for pivotal movement about a pivot axis. A spindle, to which a cutter, such as a sawblade or chipper head, is affixed, is mounted to the spindle housing for rotation about a spindle rotation axis by a cutter driver. The skewing assembly is coupled to the spindle housing to position the spindle rotation axis to a selected angular orientation to position the cutter at a selected skew angle. In some examples the cutter driver comprises a drive source fixedly secured to a frame and an extendable length universal-joint driveline assembly.Type: GrantFiled: March 19, 2007Date of Patent: January 4, 2011Assignee: McGehee Development Company LLCInventor: Ronald W.

Patent number: 7743802Abstract: A wood product assembly includes a cutter and skewing assemblies. A cutter positioning body is movable by the slewing assembly along a slewing axis. A spindle housing is mounted to the cutter positioning body for pivotal movement about a pivot axis. A spindle, to which a cutter, such as a sawblade or chipper head, is affixed, is mounted to the spindle housing for rotation about a spindle rotation axis by a drive assembly. The drive assembly includes a fixed position drive motor and a drive shaft assembly. The drive shaft assembly comprises a hollow drive shaft sleeve and a drive shaft. The drive shaft sleeve extends at least part way through the drive motor and is rotatable by the drive motor. An end of the drive shaft is slidably housed within and rotated by the drive shaft sleeve. The skewing assembly is coupled to the spindle housing to position the spindle rotation axis to a selected angular orientation to position the cutter at a selected skew angle.Type: GrantFiled: June 13, 2007Date of Patent: June 29, 2010Assignee: McGehee Development Company LLCInventors: Ronald W.

Publication number: 20100031792Abstract: A wood cutter assembly includes a saw assembly, a slewing assembly and a skewing assembly. The saw assembly includes a cutter assembly rotated about a drive axis by a drive shaft passing through an open region therein. The cutter assembly includes a cutter mounted to a cutter spindle for rotation about the open region. The cutter assembly is mounted to a spindle housing, which is pivotally mounted to a saw positioner for movement about a pivot axis. The pivot axis passes through the drive shaft transversely to the drive shaft axis. The cutter is slewed so to move the saw positioner, and the spindle housing and cutter assembly therewith, along the drive shaft. The cutter is skewed relative to the drive shaft axis over a range of skew angles by selectively rotating the spindle housing, and the cutter assembly therewith, about the pivot axis.Type: ApplicationFiled: August 5, 2009Publication date: February 11, 2010Applicant: McGehee Development Company LLCInventor: Ronald W.
