Abstract: A fence ruler for table circular saws includes a longitudinally extending profiled hollow body of mostly rectangular cross-section mountable onto a machine table. One side of the profiled hollow body is formed as a guiding leg with a protruding extension having on its front edge a guiding ruler for guiding lower work pieces. The guiding leg may also be positioned on the machine table to extend at a right angle from the same. A slide is positioned within the hollow space in the hollow body and is movable longitudinally from the outside. At least one catch protrudes from the hollow body and is guided through a longitudinal slot in the profiled hollow body that opens to the outside through an opening slot in the guiding ruler.
Abstract: A clamp to make a straight edge on a working board has a base with a lower surface to slide on a table saw and a main wall that extends upward from the base. A lower support extends outwardly from the main wall in opposite directions, and two upper supports extend outwardly from the main wall in opposite directions to define channels, wherein a reference board is placed in one channel and the working board in the other channel. A shim arm is pivotally mounted to and extends along the base. A shim support pad is mounted at the free end of the arm and its upper surface is in the same plane as the upper surface of the base. The shim arm swings out from the base so that the pad forms a support on which the working board rests to effectively increase the width of the base.
Abstract: A wood working tool includes a cutting blade, a carrier, which can receive wood, and a guide device associated with the carrier for causing movement past the cutting blade on a predetermined path, so that a timer carried by the carrier can be cut reproducibly to size. The carrier may have a groove which corresponds to the shape to be cut, which is received by the guide device, and on movement of the carrier, the interaction between the groove and the guide device causes the carrier to follow a required path. The tool can be provided with a device for allowing a number of similar articles to be cut from a single piece of material and the cutting of similar pieces can be effected automatically.
Abstract: 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.
Abstract: A board straight-lining tool to be used in conjunction with a conventional circular blade table saw for the purpose of cutting a new straight and square edge longitudinal through a board. A board requiring this new edge is placed on a base of the board straight-liner, wherein a series of toggle clamps with pressure collapsing tips are toggled closed. This secures the straight-liner to the board. A separate detachable guard support is secured to the table saw with the circular blade protruding vertically through the guard support or the blade may protrude to the fence side of the guard support. The guard support keeps the board on the same plane as the table saw table and also adds a safety feature to aid in preventing the straight-liner from coming into contact with the circular blade during the cutting operation. The board is guided past the circular saw blade while keeping the straight-liner against the table saw fence.
Abstract: A workpiece-holding fixture for use with a table saw to cut straight, parallel or tapered sides on a workpiece. The fixture comprises a channel-shaped body having clamps for removably securing a workpiece in the body, a shield supported by the body for overlying the saw blade, and retainers cooperable with the table saw fence for preventing interference between the fixture and the saw blade. A guide is provided for use in supporting successive workpieces to enable them to be uniformly tapered.
Abstract: A jig and workpiece transport mechanism for making a curvilinear cut with a conventional band saw continuously linearly translates and rotationally reorients a jig and an attached workpiece to maintain the saw line at the cutting edge in the workpiece aligned with the band saw blade.
Abstract: A guide clamp (15, 80) has a channel shape which receives the first edge of a board and which forms a straight edge (31, 87) to be slid along a saw fence clamp (23) while cutting the board along a straight line (55, 56) with a table saw (11). A top arm (27, 82) of the channel includes clamping members (35, 89) which clamp the board in the guide clamp while a bottom arm (29, 83) of the channel supports the first edge of the board a fixed distance from a table surface (19) of the table saw. A separate shim (17, 96) is positioned between the opposite, or second edge of the board and the table surface to hold the second edge above the table surface said fixed distance so that the board remains level during cutting to make a true cut on the board.
Abstract: A sheet metal cutting apparatus with sheet metal cutting member, adjustable guide member and various attachments in a portable embodiment for the mounting of and controlled feeding of a sheet metal workpiece to the cutting member so that desired straight, circular, arcuate and/or combinations of arcuate and straight cuts may be effectuated. A guide bar is disposed laterally from the cutting member and supports the adjustable guide member and the various attachments. The adjustable guide member or any of the various attachments may be selectively positioned and locked along the guide bar at a desired radial distance from the cutting member.
Abstract: The present invention is directed to a safety device for standard table-mounted saws whereby a board is firmly restrained thereon while the sawblade rotates to saw the board in a longitudinal plane. The device utilizes a pair of vertically oriented, spring-loaded, hold-down assemblies to maintain the board in longitudinal alignment with the rotating blade. The hold-down assemblies are of a generally rectangular configuration and may be conveniently mounted perpendicular to and at longitudinally spaced apart locations with respect to the board. The device of the invention is a significant improvement in safety equipment designed to prevent the sawed sections of a board from kicking back onto the operator of conventional table saws.
Abstract: A machine for nibbling sheet metal such that its edge conforms to the outline of a template held in face-to-face contact with the workpiece. A punch is slideably mounted in a cylindrical die so as to be movable to a position in which a notch in the punch, and the die form an adjustable opening for receiving the sheet metal as the template edge engages the side of the punch. The punch is reciprocated in excess of several cycles per second to progressively nibble crescent shaped sections from the edge of the workpiece until it conforms to the template edge. In a second version, the die has a slot for receiving the edge of the sheet metal as it is being nibbled so that the sheet metal and template do not buckle. Another form of the nibbling machine is employed to shape the end of a tubular workpiece mounted on an elongated anvil.
Abstract: An edging alignment tool resting atop a piece of wood to be edged is adjusted until the edge of an alignment bar coincides with the line on the piece of wood along which it is desired to cut. A gripping surface on the underside of the alignment tool is pressed into abrasive contact with the piece of wood. The alignment bar is moved out of the way and a guide rail is slid along the saw fence. The piece of wood is severed by the saw along the line indicated by the alignment bar.
