Abstract: An apparatus for making tenons and mortises includes a table with a first opening in the top surface thereof. The top surface is disposed for receiving a sliding base assembly for a cutting device having a second opening therein. A work-piece holding assembly is detachably connected to a front portion of the table. The table and sliding base assembly cooperate to define the movement of the sliding base assembly in relation to said first opening. The work-piece holding assembly is positionable at preselected angles and varying vertical positions in relation to the top surface of the table.

Abstract: A woodworking machine for cutting tenons and mortises in woods, especially window woods, and comprising at least one tenoning-and-mortising unit and at least one lengthwise profiling unit, where a length-cutting device and a roller table are associated with the tenoning-and-mortising unit, where further a transverse conveyor is provided to move the window wood into an operational position wherein the second end of the window wood shall be provided with tenon and mortise and also comprising a transfer system to transfer the window wood equipped at both ends with tenons and mortises to the lengthwise profiling equipment, said machine being designed in such a manner that its manufacture is economical and its construction is compact.

Abstract: A machine and method for cutting notches with rounded inner corners in wood pallets. The completed notches are made in one pass through the machine as the pallet passes over three successive stages of cutting. The first stage makes six vertical cuts for each notch, the inner four cuts to the depth of the notch and the outer cuts decreased in depth by the radius of the rounded corner and the outer cut being laterally separated from the adjacent deeper cut by a distance also equal to the radius of the rounded corner. The second stage, with a horizontal cut removes the wood between the inner four cuts and the third stage cuts out the rounded corner with a horizontally positioned radius cutter.

Abstract: The invention relates to a machine for end notching logs and to a method for end notching logs so that they can be incorporated into an interlocking corner configuration in a log cabin building. The corner construction is of the 1/2 dovetail configuration and the machine is designed to make one notch, rotate the log and then make a second notch whereby the resulting machine made configuration can be incorporated into a joint that is secure and properly drained.

Abstract: A woodworking machine for window frames has at least one vertical tenoning spindle, at least one further spindle for longitudinal profiling disposed diagonally with respect to the first spindle, and a further tenoning spindle fitted at the opposite side of the profiling assembly to that having the first tenoning spindle, a work table for the profiling spindle, and two sliding tables respectively for the first and second tenoning spindles and aligned with the work table of the profiling spindle. The improvement is that at least two first tenoning spindles are fitted one behind the other at an input end of the machine and are followed, in the direction of passage of a workpiece through the machine, by at least two profiling spindles, and then at least two second tenoning spindles.

Abstract: A notching machine including a first cutting stage which makes four vertical cuts in the stringer, the outer two cuts defining the sides of the notch. The second cutting stage of the machine makes a horizontal cut which first separates a portion of the stringer between the inner two cuts thereby allowing the drive shaft of the second-stage cutting blade to pass through the partially formed notch and cut away the remaining portions of the stringer between the outer two cuts to define the notch.

Abstract: Method and apparatus for cutting tenons in the ends of workpieces in which the workpiece is advanced on a rectilinear path, one or more cutting tools are reciprocated on a transverse rectilinear path which intersects the ends of the workpieces and the speed of advance of the workpieces and the speed of reciprocation of the cutting tools are varied so that the cutting tools have an effective undulating cutting path with respect to the workpieces, thus forming a series of spaced tenons thereon.
