Abstract: A dust extractor for a drill includes a housing having an engagement region for receiving the drill when connected to the dust extractor; and a latch mechanism. The latch mechanism includes a latch moveably mounted within the housing and moveable between a first position and a second position, a biasing mechanism biasing the latch towards the first position, and a catch attached to the latch. The catch has a chamfer which is arranged so that the chamfer slidingly engages the drill and moves the latch from its first position towards its second position when the drill enters the engagement region.

Abstract: An anchor installation tool has an elongated driving member with a body portion and a head portion. A retaining mechanism retains the anchor installation to the drill bit. The mechanism has a housing on the body portion with a pair of bias lugs that project through the body portion to contact the drill bit. An anchor guide slides on the body and head portion and has a holding member to hold an anchor. The anchor is held in the anchor guide and a drill bit is inserted into the driving member. Axial movement of the drill bit is transferred into axial movement of the driving member. The movement strikes the anchor and ejects the anchor from the anchor guide into a surface.

Abstract: A light line generating assembly is disclosed. The assembly includes a light generating unit and a base. The light generating unit produces intersecting light planes to form light lines on a surface. The light generating unit may further include level indicators for manual leveling of the light generating unit. The base is operable to repositionably receive the light generating unit such that the unit may be rotated with respect to the base. The base includes an attachment mechanism operable to connect the base to a supporting surface such as a wall or floor. The attachment mechanism is adjustable, and can be reoriented to permit the selective use of particular coupling devices/methods. Additionally, the light line generating assembly may include an adjustable measuring device (e.g., a protractor) moveably attached to the base.

Abstract: A permanent magnet, DC motor especially well adapted for use in power tools, and particularly hand-held, battery powered power tools. The motor includes two sets of armature coils, with each set of coils being coupled to separate sets of commutator bars on an armature. Separate pairs of brushes are used to interface with the two sets of commutator bars. A switching subsystem is controlled either manually by a user engageable switch or automatically by a controller, to connect the two sets of coils in either series or parallel configurations. The series configuration provides a greater efficiency, but with a lower power output than the parallel connection. The parallel connection provides a greater maximum power output from the motor. Thus, the operating characteristics of the tool can be tailored to better meet the needs of a work task, and in a manner than makes most efficient use of available battery power.

Abstract: The present invention is directed toward a system for forming miter joints including a miter saw and an angle gauge. The miter saw includes a platform with a kerf slot and a pair of arcuate slots. Each arcuate slot includes an associated rail located on the underside of the platform. A fence is coupled to each of the rails such that the fence may be pivoted with respect to the platform. The angle measurement tool is a one-handed tool including spring loaded paddles that measure the angle between intersecting surfaces. The angle measurement tool connects to the miter saw to permit the transfer of the measured angle to the fences.

Abstract: A tape measure includes a housing, a rule blade coilable within the housing, and an edge guide coupled to the housing. The edge guide may be oriented in either a first position, in which the edge guide contacts the edge of a work surface, or a second position, in which the edge guide does not contact the edge of the work surface. The edge guide may be permanently or releasably connected to the housing. The tape measure may further include a laser assembly that generates a laser line intersecting the rule blade and the work surface and a calibration mechanism to adjust the alignment of the laser line. In use, the edge guide may orient the tape measure on the work surface such that the laser line is generally perpendicular to the work surface edge.

Abstract: A tool incorporating a device that generates a light line on a work surface such as a wall is disclosed. The device includes a housing containing a self-leveling pendulum assembly and a light source that directs a light beam along a pathway. A redirection assembly, also contained in the housing, is capable of altering the pathway of the light beam prior to exiting the housing. In use, the device selectively generates a light line on the work surface in a desired direction.

Abstract: A handheld, portable, motorized clamping device is disclosed. The device includes a housing, a frame, a stationary clamp member, and a displaceable clamp member. The displaceable clamp member may be repositioned by a drive assembly, or may be manually adjusted. In another embodiment of the invention, the stationary clamp member may be repositioned on the frame to alter the dimensions of the clamp opening. In still another embodiment, the clamp device operatively connects to a secondary tool that engages the drive assembly.

Abstract: A metal cutting circular saw is provided with an upper blade guard which includes a first sight window disposed in a first side surface and disposed in a plane angularly offset from a plane of the blade. The upper blade guard also includes a second sight window disposed in the second side surface of the upper blade guard. A light window is disposed in a front portion of the perimeter outer surface of the upper blade guard. The upper blade guard is made from metal and the first and second sight windows and the light window are integrally formed as a one-piece member. The saw shoe and lower blade guard are configured to minimize chip spray from contacting a user.

Abstract: As system for clamping an rotary tool accessory disc or blade to an output shaft of a rotary tool comprising a cam clamping mechanism and a clutch assembly wherein the cam clamping mechanism comprises: a head element threadably engageable with the output shaft at a location axially outward of the accessory disc; a cam rotatably connected to the head element and rotatable between a clamped and unclamped position, wherein the clamped position the cam exerts a compression force axially inward against the accessory disc or blade; and wherein the clutch assembly comprises: at least one first type of disc located coaxially on and keyed to the output shaft; at least one second type of disc located coaxially on the output shaft and in planar parallel contact with the first type disc; and an inner washer having an internal bore, the inner washer located coaxially on the output shaft, axially outward of and surrounding the first type disc and the second type disc, the inner washer keyed at the internal bore to the seco

Abstract: A dust collection unit suitable for use with a hand held drilling and/or hammering tool, comprising a shroud (34) which is adapted to extend around a tool or bit (24) of such a hammering and/or drilling tool so as to collect dust in an airflow passing through the shroud which dust is generated by such a tool or bit. A tube like extension sleeve (28) extends forwardly from the shroud, with respect to such a tool or bit, which extension sleeve (28) is tapered at its forward end so as to have a forward rim which fits into a corner of a surface to be worked. A slideable sleeve (54) is slideably mounted on the extension sleeve so as to move between a retracted position in which the tapered forward rim of the extension sleeve (28) is engageable with a corner surface to be worked and an extended position in which a forward rim of the slideable sleeve (54) is engageable with a surface to be worked.
