Abstract: A miter saw has a base assembly, a table assembly assembly rotatably attached to the base assembly, and a drive assembly pivotally attached to the table assembly. The drive assembly has a motor and a blade driven by the motor. The miter saw also has a fence assembly attached to the base assembly. The fence assembly has a workpiece supporting surface for supporting a workpiece and a movable member for moving the workpiece off the workpiece supporting surface.

Abstract: A power driver may include a housing, a tool chuck and a power take off mechanism. The tool chuck may have an input shaft mounted for rotation on the housing. The input shaft may support chuck jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to rotationally drive the chuck actuating shaft relative to the input shaft. The power take off mechanism may be internal of the housing. The power take off mechanism in the CHUCK MODE may rotationally fix the input shaft to the housing.

Abstract: A tool chuck may include an input shaft. A chuck actuating shaft may be mounted for rotation on the input shaft. A chuck actuating screw may be coupled to the chuck actuating shaft. A spacer may be interposed between the chuck actuating shaft and the input shaft.

Abstract: A tool chuck may include an input shaft. A chuck actuating shaft may be mounted for rotation on the input shaft. A chuck actuating screw may be screw coupled to the chuck actuating shaft. A spring may be interposed between the chuck actuating shaft and the input shaft. Upon tightening the tool chuck, the spring may be compressed to provide force against the chuck actuating screw.

Abstract: A chuck for a drill/driver. The chuck can include an input shaft having a cavity, a chuck actuating shaft and a chuck actuating screw. The chuck actuating shaft can be received in the cavity and can be rotatable about a chuck axis. The chuck actuating shaft can have a threaded aperture. The chuck actuating screw can have a threaded portion that is threadably engaged to the threaded aperture. The jaws can be received in the cavity and can engage the input shaft. The jaws can be coupled to the chuck actuating screw such that rotation of the chuck actuating shaft relative to the chuck actuating screw translates the jaws so that the jaws converge toward or diverge from the chuck axis. The chuck further includes a device coupled to at least one of the chuck actuating screw, the chuck actuating shaft and the input shaft for limiting elastic elongation of the chuck actuating screw in an axial direction when the jaws are positioned in a fully opened condition.

Abstract: Provided are various embodiments of structures that may utilized in a power driver, particularly in a power driver having an optional reciprocating “hammer” action, for retaining an outer bearing during assembly and/or operation of the power driver. In particular, the disclosed structures provide one or more surfaces, particularly inner peripheral surfaces, that limit outward axial movement of the bearing along the input shaft. These structures may include combinations of surfaces defined by retaining means, an input shaft, biasing means and chuck shields for positioning the outer bearing within the power driver.

Abstract: A hammer drill/driver with a motor having an output member, a planetary transmission, a clutch assembly and a clutch bypass. The planetary transmission, which includes a ring gear, receives rotary power from the output member and produces a rotary output. The clutch assembly has a clutch profile, which is coupled to the ring gear, and a first pin assembly having a first follower, a first pin member and a first spring that biases the first follower into contact with the clutch profile. The clutch bypass has a bypass profile, which is coupled to the ring gear, and second pin assembly having a second follower, a second pin member, a third spring, which biases the second follower away from the bypass profile, and a fourth spring, which biases the second follower away from the second pin member. A method for operation of a hammer drill/driver is also provided.

Abstract: A drill chuck with an impacting structure that may be selectively employed to drive the jaws of the chuck into further engagement with or out of engagement with a bit. The chuck is configured so as to be capable of generating relatively high torques in a loosening direction so as to ensure that the bit can be removed from the jaws of the chuck.

Abstract: A self-tightening chuck mechanism is disclosed. The chuck mechanism has a jaw mechanism with a jaw elements which are slidably disposed within corresponding channels defined in a rotatable body. A threaded socket member, which is configured to be rotated in first or second directions relative to the jaw elements is rotatably disposed about and engaged with the jaw elements. An impact assembly is configured to interface with the threaded body to apply anti-rotational forces to the socket member to prevent rotation of the socket member to close the jaws when rotated in a first direction and open the jaws when rotated in a second direction. The thrust bearing is configured to apply a first set of forces to socket member when the socket member is relatively rotated in the first direction and a second set of forces when the socket member is rotated in a second direction.

Abstract: An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool.

The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is equalized by a set of cables and pulleys.

Abstract: A table saw guard assembly for guarding a blade on a table saw is provided. The table saw guard assembly includes a support structure and a hood assembly including at least one of a front curtain, first side curtain, second side curtain and top curtain, wherein each of said curtains are independently moveable and/or removable from the hood assembly. Furthermore, a table saw guard assembly is provided including a quick release mechanism for connecting the hood assembly to the support structure.

Abstract: A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis, a table slidingly disposed on the first rail, a support assembly disposed on the base, a saw assembly supported by the support assembly, the saw assembly comprising a motor, a cutting wheel driven by the motor, the saw assembly being pivotable about a horizontal axis substantially parallel to the longitudinal axis, and a switch electrically connected to the motor and disposed on the support assembly so that, when the motor assembly is pivoted about the horizontal axis, the switch remains stationary.
