Abstract: A tool sharpener accessory having a base mounted on a support, a pivoting member pivotally mounted on the base and pivoting in at least a seesaw motion relative to the base, the pivoting ember having an axis of rotation adaptable for extending transverse to the axis of rotation of the grinding stone, and a securing mechanism for securing the tool to the pivoting member.

Abstract: A power tool and accessories therefor including a variable speed motor for a mortiser, an integrated chisel positioning tool for positioning a chisel in a desired position, and an integrated tool sharpening device mounted directly on the power tool to permit ease and efficiency in the sharpening of tools. Additionally, an improved clamping arrangement is provided that permits firm clamping of a work piece without slippage. Greater flexibility in the hold down may be achieved by using arms for the hold down that are both rotatable about and can be translated along respective horizontal axes.

Abstract: A power tool is provided with an adjustable handle assembly. The assembly has a housing and a handle connected to the housing. The handle may be movable between a plurality of positions and has a gripping portion. There may be a lock member associated with either of the movable handle or the housing. The other of the handle and the housing would have a mating member that cooperates with the lock member to lock the handle in position. The assembly may be provided with an actuator movable between a lock position to lock the handle and an unlock position to allow the handle to be moved. The handle may extend from a rear portion of the housing.

Abstract: An apparatus for securing a workpiece comprising first and second clamp members, and a transportable elongate member to which the clamp members are mounted and are operable for being shifted between work engaging and work releasing positions. In one form, the apparatus may be configured with clamp members capable of being fully removed from the elongate member and placed back thereon while maintaining the operability of the clamp members. At least one of the clamp members may be capable of being mounted on the elongate member in a plurality of directions, or may include jaw assemblies which are removable from and/or rotatable with respect to the elongate member. In addition, the apparatus may include a base for securing the base to a work surface and a catch for securing the elongate member to the base. In another form, the base may be configured to receive and secure the elongate member in a plurality of directions.

Abstract: A power tool in accordance with the invention includes a housing having a handle connected to the housing in at least one position and extending about the rear of the housing with first and second end portions positioned at least in part off the sides of the housing such that the handle allows an operator a range of locations about the housing to facilitate an effective two-handed grip to maintain control over the power tool. The power tool may include an actuator, such as a switch, to regulate power supplied to the tool's motor, and may automatically shift to deactivate the power tool when an unintentional impact above a predetermined magnitude is received by the power tool. The power tool may also include a recess for maintaining an accessory tool and may be designed so that it is both statically and dynamically balanced in order to provide a balanced tool both at rest and during operation, and in order to reduce the amount of vibration experienced by an operator during use of the tool.

Abstract: An apparatus for securing a workpiece in accordance with the invention, such as a vise, includes a base for supporting the apparatus on a work surface, a back jaw member connected to the base for engaging a first portion of the workpiece secured by the apparatus, and a front jaw member connected to the back jaw member for engaging a second portion of the workpiece secured by the apparatus. The apparatus may include a clutched handle capable of shifting between an engaged position wherein the handle engages and drives a driven member and a disengaged position wherein the handle disengages from the driven member and is freely positionable in both a clockwise and counterclockwise direction with respect to the driven member. The apparatus may also include an accessory capable of being connected to the apparatus in order to perform additional work on a workpiece.

Abstract: A power tool in accordance with the invention includes a housing having an internal compartment with a motor therein, a handle connected to the housing for maneuvering the power tool, a working element connected to and driven by the motor to work on a workpiece, and a removable, portable power source having a first position wherein the power source is located primarily in the internal compartment of the housing and being electrically connected to the motor to provide power to the motor for driving the working element and a second position wherein the power source is located remotely from the housing and detached electrically from the motor.

Abstract: An apparatus for securing a workpiece comprising first and second clamp members, a transportable elongate member to which the clamp members are mounted for being shifted between clamped and unclamped positions to allow a clamped workpiece to be transported, and a base having a base securing mechanism for securing the base to a work surface and an elongate member securing mechanism which allows the transportable elongate member to be connected in a fixed position relative to the base to keep the secured workpiece fixed relative to the work surface. With this configuration, the elongate member and clamp members may be used in conjunction with the base and/or removed from the base and used remotely thereto.

Abstract: A cassette loading apparatus in which there is provided a clutch member having a resilient member coupling first and second sliding members. The resilient member is adapted to horizontally move along guide members provided on one of a pair of side plates for guiding a cassette holder. The second sliding member has formed therein an elongated hole along which a projection formed on the first sliding member is displaced. The length of the elongated hole is greater than the displacement of the projection corresponding to the moving distance of the cassette holder along a horizontal section of an L-shaped guide groove formed in the one side plate.
