A miter saw including a base having a support surface for supporting a workpiece. A turntable is mounted on the base for rotation about a vertical axis and a support is mounted on the turntable. A bevel angle adjustment mechanism is mounted on the support and includes a housing movable about a horizontal bevel angle axis. A cutting unit is connected to the housing for pivotal movement about a horizontal axis between a cutting position and a non-cutting position. The bevel angle adjustment mechanism supports cutting unit for movement in a first direction from a vertical position to a bevel angle position greater than 45Â from vertical. The bevel angle adjustment mechanism also supports the cutting unit for movement in a second direction opposite to the first direction to approximately a negative 5Â bevel angle position. Preferably, the miter saw further includes a biasing member, and the cutting unit is freely movable between a vertical, 0Â bevel angle position and a transverse, 45Â bevel angle position and movable against the force of the biasing member beyond the 0Â and 45Â bevel angle positions.

A power hand drill is clamped in the carriage which is slideably mounted on the vertical column. The lever arm is moved about a fixed pivot to control movement of the carriage. The lever arm is tubular and has a push rod extending from the handle into the interior of the housing to actuate a switch which, when closed, connects the power supply cord to a receptacle into which the drill power cord is plugged. The drill power switch is tied in the closed position. Therefore the user can control drill feed and operation with one hand.

A motorized saw comprising a base having a work piece support, and a cutting station at which a work piece is cut; a cutting unit including a motor, an arbor on which a saw blade can be removably mounted for rotation about an arbor axis driven by the motor, and a movable guard, movable between surround and non-surround positions relative to a lower portion of the saw blade; mounting apparatus securing the cutting unit on the base for movement between a non-cutting position remote from the cutting station and a cutting position which places the saw blade at the cutting station; a movable guard actuating apparatus connected between the base and the movable guard to progressively move the movable guard toward the non-surrounding position as the saw blade cuts through the work piece at the cutting station, the actuating apparatus includes a lost motion member permitting the movable guard to be freely moved by manual actuation thereof to the non-surrounding position only when the cutting unit is in the non-cutting position to expose the saw blade for removal; a lockout apparatus automatically contactable by the movable guard actuating apparatus when the movable guard is in the non-surrounding position for preventing movement of the cutting unit from the non-cutting position until the movable guard is returned to the saw blade surrounding position.

A miter saw including a base having a support surface for supporting thereon a workpiece and a turntable mounted on the base for rotation about a generally vertical axis. A support is mounted on the turntable for movement therewith and a saw arm is mounted on the support for pivotal movement about a horizontal bevel angle axis such that the saw arm is adjustable to cut the workpiece at a selected bevel angle, and the saw arm being mounted on the support for pivotal movement about a second horizontal axis perpendicular to the bevel angle axis to allow movement of the saw arm between cutting and non-cutting positions. A reversible fence is removably connected to the base to support the workpiece on the base. The fence has opposite ends such that one end has a vertical edge portion for supporting the workpiece during conventional miter cutting of the workpiece and the other end has an angled edge portion for supporting the workpiece during compound miter cutting of the workpiece.

The stand for a portable power drill has a base supporting an upright column on which a clamp is mounted for slideable movement to a desired height where it is fixed. A carriage is slideably mounted on the column with a bushing on each side of the clamp. A spring biases the carriage upwardly. A power drill is clamped on the carriage and the carriage can be moved downwardly relative to the clamp against the bias of the spring to feed the drill bit into the work. A lock plate having an aperture slightly larger than the diameter of the column fits over the column and is spring biased to tilt on a fulcrum on the underside of the clamp. When tilted, the aperture edges engage ("and bite") the column to support the carriage and drill. The plate has a pad which is depressed against the spring bias to release the plate so the clamp and carriage can be raised or lowered.

A cutting tool including a base having a turntable pivotally mounted on the base for movement about a vertical axis, a support member mounted on the turntable, and a saw arm mounted on the support member for pivotal movement about an axis between cutting and non-cutting positions. The saw arm has a saw blade including a lower portion. The saw blade is mounted for rotation about an arbor axis. A lower blade guard is supported on the saw arm for pivotal movement about the arbor axis between a surround position wherein the lower blade guard surrounds the lower portion of the saw blade and a non-surround position wherein the lower portion of the saw blade is exposed for cutting. The cutting tool also includes a cam plate mounted on the saw arm, and a cam follower mounted on the support member such that movement of the saw arm between the non-cutting position and the cutting position causes pivotal movement of the lower blade guard between the surround position and the non-surround position.

A pivot assembly for mounting an operating member on a base member for pivotal movement about an axis at an optimum axial position comprising: a pivot shaft having an axis, a base member and an operating member having axially opposable first and second inner surfaces respectively, a first mounting apparatus for mounting one of the members at a fixed axial position on the pivot shaft, and a second mounting apparatus for mounting the other member on the pivot shaft for relative rotational movement, and for axial movement to a position where the first and second inner surfaces axially oppose each other with an axial space therebetween, and the other member is at the optimum axial position. The second mounting apparatus includes, a pair of compressible disk springs mounted to be in a biased condition when the other member is at the optimum axial position. The disk springs constantly tend to move the other member in one axial direction away from the optimum position.
