Abstract: A dual slice bread machine for cutting slits into loaves of bread perpendicular to a conventional bread slice. The present system has an actuating rack having a series of regularly spaced piercing knives mounted thereon. The actuating rack is configured to be raised and lowered automatically. In use, a loaf of bread is placed underneath the actuating rack. When the actuating rack is lowered, the knives puncture the loaf, creating a series of vertical slits along the length of the loaf. The loaf is then cut with a conventional bread slicing machine where the slices alternate between a slice that dissects a vertical slit and a cut that is positioned exactly in between two adjacent vertical slits. This creates a loaf with slices having a centered living hinge capable of being easily folded and separated into equal halves.

Abstract: An in-line indexing mechanism as part of a work-stop system which employs a lead screw to alter the relative distance between a work-stop plate and a swing arm—as well as alignment pins and springs to maintain contact and rigidity between this work-stop plate and swing arm—in order to precisely alter the parameters of a workpiece plane. In particular, the indexing mechanism of the preferred embodiment resides within the extension of an arm, and is located, by default, within the workpiece plane; the act of indexing therefore exerts force upon a workpiece along a coincident axis within said workpiece plane. Additionally, the indexing mechanism may be removed from the workpiece plane, by way of axially rotating the arm, without abandoning the original workpiece parameter and adjustment values.

Abstract: Operating a power saw between a pair of parallel guide rails, which engage opposing sides of saw base plate to constrain the motion of the saw to a straight path, allows for precise cuts. A set of two or more fences allows for multiple cutting options. In some embodiments, non-parallel fences coupled to the guide rails allow for precise cuts at more than just a single angle. In some embodiments, two fences may engage opposing sides of the object to be cut simultaneously, holding the object more securely with respect to the guide rails than would a single fence. A possible clamping force holding the two fences against the object allows the miter guide to remain fixed relative to the object so that the user's hand may be freed for another task, such as holding the saw with both hands.

Abstract: An alignment device for a portable motorized miter saw may allow a user to easily reproduce cuts of the same length, even when the miter saw is taken off and replaced back on a portable miter saw stand. The alignment device includes a three piece connector that allows for easy set-up of wings on either side of the saw, which are used to support the material being cut. Because the wings attach directly to the saw itself, the wings stay in exactly the same relationship to the saw blade. Thus, when a stop is attached to the wing, material can be cut to the same size lengths, even though the saw may be taken down one day and set up another day.

Abstract: A saw machine fence adjustment mechanism installed on a base member of a worktable, including a fence body, a pivot shaft mounted on the fence body, a spanner coupled to the pivot shaft, a spring member positioned between the spanner and the fence body and a locking device on the pivot shaft adapted for locking the fence body. To adjust the position of the fence body, the spanner operated to rotate the pivot shaft to move the locking device away from the base member for allowing adjustment of the position of the fence body. After adjustment of the position of the fence body, the spanner is released to allow the spring member to bias the pivot shaft to its former angular position and to force the locking device into engagement with the base member to provide quick adjustment of the position of the fence body to provide sufficient support.

Abstract: A sub fence clamping system incorporating c-clamps (9) which have a cylindrical legs (1) placed into vertical holes in a sub fence (11), rather than over and onto the work guiding face of the sub fence. Now vertical boards can be milled safely using this system. Pressure to clamp the sub fence to main guide fence is created by a threaded screw (4), cam (8) or other device. The end of the cylindrical leg can be made to protrude (7) toward the opposing leg, insuring pressure at that point only. Replacement sacrificial sub fences (10) are easily drilled to receive the cylindrical end of the clamp. These sacrificial sub fences are used on tablesaws (12) for rabbeting, and shapers for making cuts needing the zero clearance opening of a safer sacrificial fence. With no clamp on the face of the sub fence, steel plates for a magnetic feather board can be attached to a wood sub fence (13).

Abstract: A workpiece stop is provided for a power tool such as a miter saw, wherein the stop is selectively movable to various positions for respective modes of operation. In one position, the stop is stored out of the way during non-use. In another position, the stop acts as a length-of-cut stop. In yet another position, the stop acts as a workpiece guide, especially useful for supporting crown molding during cutting. An embodiment of the stop includes an elongate main body portion with a guide tab portion and a stop tab portion projecting from the main body portion, and the stop is preferably mounted for selective movement both slidably and pivotally. Depending on the position of the stop, the guide tab portion or the stop tab portion are positioned to project adjacent a workpiece support surface on the saw to limit a position of a workpiece.

Abstract: A shingle cutter that is portable and can be temporarily attached to and used on the roof with the roofing nails used on the job. The power for cutting results from the housing of the cutting wheel being manually drawn back towards the operator. The shingle cutter has a structural base and two vertical end walls that support a rectangular rack, which holds the cutting block. In one version the rack drives a pinion, which in turn drives the cutting wheel. In a second version, the cutting wheel is free to rotate as it is pulled through the shingle. The cutting block is constrained by rollers in contact with the top and bottom of the rectangular guide bar so that the cutting wheel moves to perform a shearing function with an abutting shear ledge mounted on the structural base.

Abstract: A novel precise, multiple indexing jig used in conjunction with power tools, especially a power saw, is disclosed. The jig includes a longitudinal indexing rod that precisely locates and supports by pivotal articulation, a plurality of swing arms. The swing arms can be rotated onto the table and used as stops to assist in positioning a work piece on the device that is to be worked at a specific location, such as the cut length for a saw. When they would be in the way of a work piece, they can be rotated away from the table. The indexing rod is positioned parallel to a guide fence that also locates the work piece. A series of location supports are also located on the indexing rod and further support the swing arms. An alternative embodiment enables the guide fence to also index with the swing arms, thereby increasing the structural stability of the swing arms when they are positioned as stops.

Abstract: The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size.
