Abstract: A tile saw comprising a base, a table supported by the base and configured to support a workpiece, a guide rail upon which the table is supported and moveable along a longitudinal axis, a saw unit coupled to the base, and a roller assembly for supporting the table upon the guide rail. The roller assembly includes a first roller rotatably supported by the table and engaged with a first portion of the guide rail, and a second roller rotatably supported by the table and engaged with a second portion of the guide rail that is different than the first portion. The second roller is translatable relative to the table in a direction toward the guide rail. The roller assembly further includes a spring biasing the second roller toward the guide rail.

Abstract: An auxiliary handle can be used with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch, and a grip coupled to the shaft. When the first protrusion of the first clamp engages the first notch and the grip is rotated relative to the second clamp, the second clamp is moved toward the first clamp, such that the first protrusion engages the first notch and the second protrusion engages the second notch to couple the auxiliary handle to the housing of the power tool.

Abstract: A powered fastener driver includes a cylinder and a drive piston within the cylinder being acted on by a driving force resulting from a pressure differential. The powered fastener further includes a drive blade coupled to the drive piston and operable to drive a fastener, and an adjustable valve for selectively introducing air from ambient atmosphere into the cylinder, thereby changing the pressure differential acting on the drive piston. By adopting a self-contained vacuum generating means as described above, the present invention does not rely on any external vacuum source and powered fastener driver can be used and carried with conveniently.

Abstract: An articulating head of a power tool is disclosed in the present invention, which includes a base member adapted to couple to a main body of the power tool, an articulating member pivotably connected to the base member, and a locking device coupled to the articulating member for locking an orientation of the articulating member with respect to the base member. The base member contains a first power transmission part which is capable of receiving mechanical driving power from the main body of the power tool. The articulating member contains a second power transmission part mechanically coupled to the first power transmission part. The locking device has an actuation lever rotatable about a pivot axis between a free position and a lock position.

Abstract: A power tool having a removable head, a motor, a trigger, and a trigger stop movable between first and second positions. In the second position the trigger is unlocked to permit activation of the motor. A linkage is coupled to the trigger stop and is positioned at a first radial distance from the first central axis. A plurality of actuators extend from the head and are positioned at a second radial distance substantially equal to the first radial distance. When the head is coupled to the handle in a first rotational orientation, one of the plurality of actuators engages the linkage to move the trigger stop to the second position, and when the head is coupled to the handle in a second rotational orientation different from the first rotational orientation, another one of the plurality of actuators engages the linkage to move the trigger stop to the second position.

Abstract: The invention provides, in one aspect, a pneumatic fastener driver including a cylinder and a piston positioned within the cylinder. The piston is moveable between a top-dead-center position and a bottom-dead-center position. The driver also includes a magnetic latch emitting a magnetic field that magnetically attracts the piston and is capable of holding the piston in the top-dead-center position with a magnetic force. The magnetic latch is adjustable to vary the magnetic force acting on the piston for driving fasteners into a workpiece at different depths.

Abstract: A spindle lock (10) includes a detent arrangement including springs (25) acting on projections (30), each projection engaging one of a pair of recesses (40, 41) to control and buffer the rotation of a spindle (13) and to delay the engagement of locking elements (26a, 26b). A compact, reliable mechanism with a high degree of modularity is achieved by providing the recesses in an inner rotor (31) and the springs and projections in an outer rotor (18) that extends about the inner rotor.
