Patent number: 10065337Abstract: Disclosed is a self-powered timber slasher. The self-powered timber slasher includes a trailer and a powered circle saw mounted on a first end of the trailer, wherein the powered circle saw is configured to cut timber. Further, the self-powered timber slasher an engine mounted on a second end of the trailer, wherein the engine is configured to generate power for operating the powered circle saw. Yet further, the self-powered timber slasher a wireless controller electrically coupled to the powered circle saw. The wireless controller is configured to control operation of the powered circle saw based on a command received over a wireless communication channel.Type: GrantFiled: August 17, 2017Date of Patent: September 4, 2018Assignee: SPRUCE CREEK MECHANICAL L.L.C.Inventor: John Steciak, Jr.

Publication number: 20120024426Abstract: A debarking mechanism including of rotatable debarking shafts extending parallel to an advancing direction (A) of the logs to be fed therethrough, which are provided with teeth extending beyond the circumferential surface of the shaft. At least the uppermost debarking shaft is moved sideways towards the inner part of the debarking mechanism in such a way that each debarking shaft directs an impact effect on logs colliding with it and moved by the debarking shafts located in a lower position. The circumferential speed of the debarking shaft is selected to be the greater the higher the debarking shaft is positioned. A free passage is arranged for the bark passing over the debarking shaft.Type: ApplicationFiled: September 19, 2011Publication date: February 2, 2012Applicant: Andritz OYInventor: Pekka KOKKO

Patent number: 7556071Abstract: A debarking mechanism including a number of rotatable debarking shafts extending parallel to an advancing direction (A) of the trees to be fed therethrough, which are provided with a number of teeth extending beyond the circumferential surface of the shaft and the debarking shafts being adapted to each other in such a way that the presently processed trees make a circular motion (C) in the debarking mechanism, in which motion the trees are forced upon the support surface constituted by the debarking shafts effected by the rotary motion of the debarking shafts. The uppermost debarking shaft has been fitted together with a guiding surface, the surface together with the uppermost debarking shaft forming a slot convergent in the direction of rotation of the debarking shaft.Type: GrantFiled: March 29, 2005Date of Patent: July 7, 2009Assignee: Andritz OyInventor: Pekka Kokko

Patent number: 6976515Abstract: The modular drive wheel for log processors includes a tubular midsection sandwiched between a pair of annular rings mounted concentrically on opposite ends of the midsection. The midsection has a resilient outer surface extending around the midsection. The pair of annular rings each have a radially spaced apart array of notches therearound. The notches in the radially spaced apart arrays of notches are sized to snugly receive in releasable locking engagement therein links on opposite ends of chain segments extending between the pair of annular rings. The drive wheel further includes means mounted between the pair of annular rings for selectively forcing apart the pair of annular rings along a longitudinal axis of symmetry of the midsection.Type: GrantFiled: October 3, 2003Date of Patent: December 20, 2005Inventor: Alain Duval

Patent number: 6776202Abstract: A log-peeling machine for removing bark from logs to simulate hand peeled logs. A log is held in position on a pair of movable log support frames, each having multiple adjustable log support and drive roller assemblies. An independent high-speed cutting head is movable along the length of the log removing bark in longitudinal strips by adjustably following the log surface which is raised and lowered and rotated for engagement with the cutting head.Type: GrantFiled: September 16, 2002Date of Patent: August 17, 2004Assignee: W.G. Benjey, Inc.Inventors: Alan Chester Dziesinski, Randy William Patterson
