Abstract: An apparatus (100), including: a push block (100) including: a first side (120) and a second side (122), each configured to abut and slide along a fence of the table saw; and a bottom (124) including a first tunnel (130) and a second tunnel (132) and an immovable dividing wall (134) therebetween. When the first side abuts the fence the first tunnel is configured to straddle a blade throughout a first tunnel first range of fence positions (R12), and the second tunnel is configured to straddle the blade throughout a second tunnel first range of fence positions (R34). When the second side abuts the fence the first tunnel is configured to straddle the blade throughout a first tunnel second range of fence positions (R45), and the second tunnel is configured to straddle the blade throughout a second tunnel second range of fence positions (R23).

Abstract: A push block for a woodworking tool comprises at least heel member at an end of the push block and the heel member is passively actuatable to an extended position to engage a trailing end surface of a work piece to advance the work piece by a working element. The push block also includes a wall member along a first side of the push block to serve as a barrier between a cutting element and an operator's hand. In addition, the push block includes a handle that is disposed obliquely relative to first and second sides and a longitudinal axis of the push block.

Abstract: A device for cutting food includes a slide operable to receive a food product that is slid across the slide so as to perform a cutting procedure. A cutting blade including a cutting edge is included. A switch is included operable to switch the device from a neutral position in which the cutting edge is at least one of covered and recessed, to a cutting position in which the cutting edge is neither covered nor recessed.

Abstract: A push block including a heel that has a stored position and an operative position. Accordingly, when the push block is disposed face down on a flat workpiece and the heel is in its stored position, the push block can effectively perform the functions of a flat face push block. When, on the other hand, the heel is disposed in its operative position and the push block is disposed so that the heel can engage an end edge of the workpiece, the push block can effectively perform the functions of a fixed heel push block.

Abstract: A push stick comprises a body providing a bottom surface and a heel member that protrudes beyond the bottom surface; and a slide-out ruler that is selectably positionable to extend from the body. The push stick is a safety device that can be used to push a workpiece past a blade or bit while keeping an operator's hands out of harm's way. The ruler allows an operator to use the push stick to make measurements, such as setting the height of a cutting tool relative to a workpiece table.

Abstract: The invention has two main components: a straight edge board and a pressure arm assembly. When used together, the two components will allow a table saw operator to safely and accurately straight line rip crooked material, typically lumber, in one continuous pass. When used without the straight edge board, the pressure arm assembly will keep the material tight against the table saw's rip fence while rip sawing or performing additional sawing techniques.

Abstract: An adjustable pushing apparatus (50) for safely moving a work piece (22) past a cutting tool (16). The apparatus includes a body (52), a first leg (56), a second leg (58) and a moveable center leg (60) defining a leg side surface (74) and two adjustable-width tunnels (62, 64) through which a cutting tool may pass. A handle (54) is moveable along a top surface (82) of the body to provide a balance of forces on both the inside cut portion (24) and the outside cut portion (26) of the work piece. Non-slip work piece-contacting surfaces (76) provide positive engagement with the work piece. A balance support device (84) may be attached to either the first or second leg at a plurality of vertical heights to balance the apparatus when the work piece is too narrow to make contact with a work piece-contacting surface on both side of the cut line (C). In one embodiment (200) a bridge handle (202) is used to maintain balanced forces on both sides of the cut line.

Abstract: The device according to the invention has a sensor (5) for generating and detecting an electromagnetic field situated in the vicinity of a moving part (1) that should not be touched. The device according to the invention also has an evaluation unit (8) that is connected to the sensor (5) in order to evaluate sensor signals that can be generated by the sensor (5), wherein the evaluation unit (8) can generate an evaluation signal. Finally, a control unit (9) connected to the evaluation unit (8) is provided, which is designed and can be operated so as to control the movement of the part (1) as a function of the evaluation signal.

Abstract: A hand held pushing tool for use with cutting and abrasive tools is formed as a planar disk. The disk has a first side surface, a second side surface, a first predetermined thickness and an outer peripheral edge. The outer peripheral edge has at least one notch. The notch extends from the first side surface to the second side surface and is located orthogonally to the outer peripheral edge. The notch has a depth less than a thickness of a work piece. When the notch engages the work piece, the pushing tool will safely guide the work piece into and through the cutting or abrasive tool. The pushing tool is shaped as an octagon having a plurality of varying size notches about its outer peripheral edge. The tool may be inverted to use the notch to hook the work piece and draw it back past the cutting or abrasive tool.

Abstract: A burn side of a compact disc is maintained in contact with edges of triplet blades while the disc is moved relative to the blades. In one embodiment, the disc is manually moved into and out of an enclosure where the blades scratch the burn side. In another embodiment, a paper shredder provides power to counter rotating rollers that transport the disc through an enclosure where the blades scratch the bum side.

Abstract: A safety push tool for use with table mounted cutting tools. The push tool is of the type having a carrier guide body with an underside adapted to rest on a work piece to be moved along a cutting tool. The safety push tool has a handle portion and the improvement of the present invention is the construction of the back heel member which is held at the slot of the back of the tool. The back heel member is a U-shaped device which fits over a slot over the back of the tool. The back heel member is a U-shaped device which fits over a support arm and can be rotated from a first position where two separate arms depend downwardly from the underside. It also can be moved in a second position where a cross member headstock extends below the underside of the safety push tool.
