The microtome has a sample carrier movable along a first linear guide and a hand drive movable along a substantially linear path of motion that is substantially perpendicular to the direction of motion of the sample carrier. A deflecting device is provided to deflect the motion of the hand drive into a motion in the direction of the linear guide of the sample carrier. By deflection of the paths of motion between the hand drive and the sample holder, the motion of the hand drive can take place substantially horizontally forward and backward and convert the motion of the hand drive into a motion of the sample carrier which is substantially perpendicular to the motion of the hand drive. The cutting motion takes place in a substantially vertical direction, so that the sections can be removed or washed away from the inclined back surface of the cutting knife or knife carrier.

A log processing machine and associate method employs one or more log guides to make joinery cuts in a processed log which has at opposed edges of the processed log the raw log's natural external contour. In a preferred embodiment of the invention, each log guide includes a straight edge and is attached to the processed log to create an artificial straight edge for guiding the processed log through the joinery machine. Prior to attachment, centerlines are marked on the log guide and the processed log, and the centerlines are aligned when the log guide is attached to the processed log. The processed log, with the log guide attached, is then moved through the machine with the aid of computer control while the straight edge of the log guide follows a fence. In this manner, the position of the processed log and its centerline are always known so that the computer can make the programmed joinery cuts with high precision. An alternate embodiment of the invention employs one or more fence extensions as log guides. The fence extensions are positionable in guide channels formed in the contoured edges of the processed log. A further embodiment of the invention employs an opposed pair of clamping / alignment elements which are controlled by a computer to align and guide the log through the joinery machine.

The invention is a device for peeling one or more individual layers of a multilayer shim. In detail the device includes a platform having a surface with a recess. A mechanism is mounted in the recess for mounting the shim and a moving the shim upward such that a portion of the shim is above the surface. A blade assembly is rotatably mounted to the platform, which is rotatable in a plane parallel to the surface. The blade assembly includes a cutting blade mounted thereon, such that said blade is in slidable contact with the surface and movable over the recess. Thus shim can be raised by the mechanism and the portion of the shim requiring removal can be raised above the surface and the blade assembly thereafter can be rotated causing the cutting blade to shear off the portion of the shim above the surface.

A mechanism and method is provided for controllably loading multiple food loaves into the slicing station of a continuous slicing machine. The parallel loaves that are engaged by a common loaf feed drive or side-by-side, independent loaf feed drives are engaged by the loaf feed drive or drives simultaneously such that the interface or seam between a preceding loaf and a trailing loaf in different loaf feed paths are located substantially at the same location during slicing of two side-by-side loaf streams. A clamp device is provided that clamps multiple food loaves when loaded to move along the parallel food loaf paths together, wherein the clamp device can be released once the multiple food loaves are simultaneously engaged by the loaf feed drive.

A food slicer and grater is provided. In one implementation, the food slicer and grater may include an adjustable base including a first and second base portion. The first base portion may be slidably moveable relative to the second base portion in a stepwise incremental fashion. The food slicer and grater may also include a food cutter element configured to be removably coupled between the first base portion and the second base portion. The food cutter element may also be configured to be removably coupled to an outer surface of the adjustable base or the outer surface of another food cutter element.

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.

A microtome includes a knife holding device for a cutting element (16) and a specimen holding device (12). Associated with the specimen holding device (12) for a cutting movement is a first drive device (18) and associated with the specimen holding device (12) or the knife holding device is a second drive device (38) for a feed movement. A sender (20) is associated with the first drive device (18) and is connected with an electronic control means (26). A first operating element (28) controlling the first drive device (18) has a standard mode, in which the cutting movement of the specimen holding device is controlled by rotation of the first operating element (28), and a second mode, in which a continuous cutting function is activated by pressing the first operating element (28). A second operating element (44) controlling the second drive device (38) also has corresponding rotary and pressing modes.

The description refers to a mill saw with a saw gate (3) driven via a slider-crank drive (4), whose parallel saw blades (5), which cut in only one stroke direction, are provided with a bias, and with a feed conveyor (6) for the stock to be cut, which is driven intermittently during the cutting stroke of the saw gate (3) as a function of the cutting speed by means of at least one motor (10) separated from the slider-crank drive (4) and connected to a controlling system (12). To achieve favorable construction features, it is suggested that the controlling system (12) connected to a signal transmitter (17) for a preset position of rotation of the slider-crank drive (4) controls the motor (10) in dependence on the response of the signal transmitter (17) according to a stored control program for one conveying step adaptable to the respective stroke frequency of the slider-crank drive (4).

An end-dogging head saw is disclosed comprising a log cradle for supporting a log, a log-turning device for rotating the log into proper alignment with a pair of band saws, the log-turning device depending from overhead log carriages which move the log into contact with the band saws, and a carriage drive for powering the overhead log carriages, whereby short logs can be quickly and efficiently processed. The invention also seeks to provide a method for using the apparatus, comprising rotation of a log through 360 degrees to allow for cutting at any desired angle along the length of the log. The method allows for maximal recovery of high-quality lumber.
