Publication number: 20140261892Abstract: A specialized wood splitting tool and chopping block, used together, enable cutting kindling from ordinary firewood in an effective and safe manner. The splitting tool uses leverage in addition to downward momentum of the cutting head to split wood. The metal handle and metal cutting head are preferably formed from a single piece of steel, in a perpendicular configuration similar to an adz. A splitting wedge blade within the handle exerts transverse shear forces to enhance splitting, and flat upper surfaces of the cutting head and the handle near the joint provide a striking surface. A complimentary chopping block for bracing logs of various diameters in a steady upright position has a V-shaped recess that is open on one end. The chopping block provides resistance to the unique leverage of the splitting tool during the splitting action.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventor: Dana Clarke

The strands have a length of between 200 and 350 mm in the direction of the wood fibers and have a width of between 1 and 15 mm. The strands are fabricated from profiled logs. In the cross-section of the logs, residual areas outside a center piece are defined, the center piece being the area intended to be dissected into beams or boards at a later stage. The residual areas are provided with longitudinal slits by cutting or sawing. The strands are then cut out of the residual areas until the residual areas are entirely removed.Type: GrantFiled: August 8, 1997Date of Patent: August 10, 1999Inventor: Hans Dietz

Patent number: 5921300Abstract: A power log splitter includes a base (28) and a wedge (12) and a ram (34) mounted on the base for receiving a log (31) lengthwise between them. A motor (16) turns a cam means (26) to deliver a series of short, quick blows onto one of the wedge (12) and ram (34), to generate strokes by which the wedge (12) splits the log (31). Preferably, there are more than two strokes per second; each stroke preferably has a duration of not more than about 0.05 second and the length of each stroke is preferably not more than 5 percent of the log length capacity L.sub.m, typically not more than 0.75 inch. The device includes a worm shaft (36) and transmission box (38) to urge together wedge (12) and ram (34) in a motion that is independent of the strokes produced by the rotating cam means (26).Type: GrantFiled: January 14, 1998Date of Patent: July 13, 1999Inventor: Kelvin M. Smith

Patent number: 5921299Abstract: A firewood splitting machine is composed of a support frame, a cutter mounted on one end of the support frame, an oil pressure cylinder mounted on another end of the support frame, and an oil injecting device mounted in the support frame. The oil pressure cylinder consists of a cylindrical body, a piston, a rod member, a subsidiary piston, and a subsidiary rod member. The piston is located in the cylindrical body such that an oil pressure space is formed between the piston and a rear end cover of the cylindrical body. The rod member is fastened at one end thereof with the piston such that another end of the rod member is jutted out of a front end cover of the cylindrical body. A pivoting hole is extended along the direction of the longitudinal axis of the rod member such that the pivoting hole is in communication with the oil pressure space.Type: GrantFiled: December 4, 1997Date of Patent: July 13, 1999Inventor: Wun-Hui Liu

Patent number: 5894873Abstract: Logs are cut to firewood length and split on a trailer that has a jacking foot at the trailer tongue and that defines an elongated bed for supporting the log lengthwise of the trailer. A superstructure pivotably supports a chainsaw for cutting the log, and a driven roller engages the top of the log to feed it incrementally into the cut-off saw's path. A conventional wood splitter is also incorporated in the same trailer.Type: GrantFiled: September 30, 1997Date of Patent: April 20, 1999Assignee: Tiberwolf Manufacturing CorporationInventor: Jeffrey Weeks

Patent number: 5791389Abstract: Apparatus and method for processing relatively large tree logs into relatively small firewood logs using two spaced apart cutting stations, a central conveyor, a transfer station and a splitter station wherein relatively large tree logs are placed sequentially onto an entrance portion of each of the two spaced apart cutting stations and are cut into rounds which are discharged onto the conveyor and moved to a transfer station. Each round is moved into a splitter station wherein each round is moved over splitter blades to form firewood logs. The splitter blades are mounted in support members secured to a square frame having spaced apart opposite sidewalls wherein the distance between each two aligned support members is greater than the distance between opposite sidewalls.Type: GrantFiled: March 28, 1997Date of Patent: August 11, 1998Assignee: Yvonne CompanyInventor: Charlie Valdez
