Abstract: The cutting machine comprises a horizontal knife (17) for cutting a block (40) into plates (41). To allow for removal of a stack of plates (42) before the whole block (40) has been cut, a removal means comprising a removal conveyor (32) is provided. After completion of the last cut, the knife (17), after reversal of its cutting edge, will be entered into the cutting gap (43) again and be lifted, thus allowing a separating member (34) of the removal conveyor (32) to enter the resultant gap (44). By driving the conveyer belt (12), the stack of plates (42) is transferred onto the removal conveyor (32).

Abstract: The portable sawmill is constructed on a frame having a series of mechanisms for loading and manipulating a log thereon and removing boards cut from the log. Powered tines load a log onto a vertically adjustable log deck, the deck including powered mechanisms for turning and securing the log in the desired orientation for cutting. Cuts are made by a horizontally traveling band saw. The saw has no vertical adjustment. Board thickness is determined by the height of the vertically adjustable log deck. Cut boards are removed by a board sweep that pushes the board laterally from the top of the log onto a tray. The saw travels along the tray to push the board longitudinally onto a suitable platform for transport. All of the above mechanisms are controlled hydraulically from a single operator station on the mill, thus freeing the operator from many manual tasks and increasing production.

Abstract: A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.

Abstract: A bi-directional cutting band mill apparatus utilizes two band saws mounted on a carriage for cutting horizontal sections from logs through successive back and forth passes across each log as the carriage reciprocates on a lower frame wherein a section of the log is cut with one band saw in one pass and then a next section of the lumber is cut by the other band saw as the carriage travels in the opposite direction in the following pass. The bi-directional cutting band mill apparatus includes structural elements that allow for the coincident raising and lowering of both band saws and structural elements that provide for the sequential and incremental adjustment of each band saw preparatory for cutting the sections from the log so that each respective band saw can be positioned for making the appropriate depth of cut through the section of the log during that respective pass of the respective band saw.

Abstract: A method and apparatus for slicing, lifting and carrying round bales or the like. The method for slicing the bale consists of making a radial cut through the length of the bale. The radial cut causes the circumferentially wrapped bale fibers to be cut which causes bale to open up. A partial radial cut, leaving the outer bale fibers uncut, can be made leaving bale substantially in a cylindrical shape to facilitate easy transport with a forklift like carrier. The apparatus consists of a mast assembly mounted to raiseable three point hitch of an agricultural tractor or the like. A pair of parallel forks are directly attached to mast and engage the curved sides of bale so as to lift and support bale for easy transport. A hydraulically activated knife assembly is attached to mast and forks. The knife has serrated teeth which cut through bale when knife reciprocates. A bumper or work guide when attached to the end of forks holds bale during cutting process.

Abstract: A hydraulically powered treelength log sawing apparatus has a log support lined with teeth opposing the outwardly-directed sawing force generated by its driveshaft-pivoted chainsaw. The chainsaw is driven by a hydraulic motor whose fluid exhaust flows through a conduit to an adjustable restriction which creates a backpressure in the fluid in the conduit. The magnitude of the backpressure is directly related to the speed of the motor and the saw, and the backpressure is directed to a hydraulic cylinder which forces the chainsaw into sawing engagement with logs on the support, thereby prevent stalling of the saw and in general causing the saw speed and engagement force respectively to be self-compensating and requiring no attention from the operator during sawing.

Abstract: A chain saw attachment for mounting a chain saw used to cut reclined logs lengthwise includes a substantially right parallelepiped frame which straddles but does not contact the log. The frame is supported by a supporting surface independent of the log and cooperates with mounting means for rigidly mounting the chain saw in a cutting position. The frame is mounted on feet which permit the frame to be slid along the supporting surface, typically the ground. The mounting means includes two sets of clamping members for gripping opposite ends of a saw bar of the chain saw. Each set is supported by a vertical chain saw support member that is vertically adjustable to vary the level of the chain saw's cutting plane relative to the log. Each chain saw support member mounts a nut that is engaged by a threaded rod, rotation of which causes the chain saw support member and hence gripped chain saw to move vertically. Both threaded rods mount respective sprockets which are interconnected by a drive chain.
