摘要： A portable circular saw includes motor-and-gear case pivotally supported on a guide shoe by a rear pivot mechanism for rotation about a transverse rear pivot axis, thus allowing for selective adjustment of the blade cutting depth on the opposite side of the shoe. In such an arrangement, the depth of cut setting is increased and decreased when the motor-and-gear case is rotated relative to the shoe in respective first and second directions, while an upper pivotal blade guard, which is mounted on the motor-and-gear case for rotation about the spindle, rotates in opposite rotational directions in response to respective increases and decreases in the depth of cut setting. Cam and cam follower mechanisms are provided for maintaining the riving knife and the blade and shoe in the same relative angular orientation in a fore-and-aft cutting plane regardless of the depth of cut setting. Such riving knife actuation is accomplished by such mechanisms in response to the rotation of the rear-pivoted motor-and-gear case and the corresponding opposite rotation of the front-pivoted upper gear case.

摘要： A power tool includes a table. A shaft is disposed on the table and has an axis. A support housing supporting a motor and a working tool driven by the motor is disposed on the shaft adjacent to the table. The support housing is axially movable along the shaft and being laterally pivotable about an axis of rotation. A locking mechanism is further provided for locking the support housing at a predetermined lateral position, wherein the locking mechanism may include a handle disposed on the shaft, the handle being rotatable in two directions with respect to the table, such that, upon rotation of the handle in both directions from a neutral position, the handle urges the support housing into contact with the table. The shaft may be rotatable relative to the table. The locking mechanism may further include a first camming surface disposed on the table and a second camming surface disposed on the shaft and engaging the first camming surface. Alternatively, the shaft may include a first surface having a first thread disposed thereon in a first orientation, and a second surface having a second thread disposed thereon in a second orientation, the first and second thread intersect forming a V-shaped thread. The table may then include at least one protrusion slidable along the first and second threads.

摘要： A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used. The pair of movable fences are located on opposite sides of a working tool such as a saw blade. A fixed clamping arrangement is associated with each movable fence and provides a single point actuation member for each movable fence to clamp the movable fence to the fixed fence such that the movable fence is vertically aligned and flush with the fixed fence. In one embodiment, each movable fence is provided with a gap-filling flap which is pivotably secured to the movable fence to be movable between a lower and an upper position. In its lower position, the gap-filling flap minimizes the gap between the movable fence and the working tool. In its upper position, the gap-filling flap provides additional support when working with taller or thicker workpieces. The workpiece-supporting fence further includes a fence position indicator which allows for the positioning of one or both of the movable fences for providing clearances for a specific miter and/or bevel cut. In addition, the workpiece-supporting fence incorporates a detent system for locating the fence at tone or more of the most popular miter and/or beveling settings.

摘要： A compound miter saw has a unique locking system for locking the bevel angle support housing to the table assembly once the desired bevel angle has been set. The locking system includes a cam and a handle each with an angular cam surface. When the two cam surfaces are aligned, the support housing is free to pivot around a supporting shaft. When the handle is rotated on the shaft, the two cam surfaces are moved to a non-aligned position. This non-alignment of cam surfaces causes axial movement of the cam along the shaft which in turn forces the support housing against the table assembly to lock the support housing in the desired bevel angle.

摘要： A tool bit such as a screw driving bit for use with a rotary power tool is conventiently stored in a cavity in the rotary power tool housing when not in use in a power tool chuck. The tool bit is retained in the recess by frictional engagement with a retainer spring. A push-button protruding from the rotary tool housing communicates with the bit holding cavity and retainer spring in a manner such that, upon depression of the push-button, the retainer spring is moved out of frictional engagement with the bit to enable its release from the storage cavity.
