Abstract: A power tool having one or more sound damping members which reduce sound and/or vibration from one or more parts of a power tool. The sound damping member can reduce sound and/or vibration from static or dynamic parts of a power tool. The sound damping member can reduce noise and/or vibration from one or more rotating or moving parts of a power tool and its housing or internal structure. Methods, means, controls, systems and practices for reducing or eliminating undesired sound from a power tool are disclosed.

Abstract: A jigsaw generally includes a housing containing a motor activated by a trigger assembly. The housing defines a window. A shoe member pivotally connects to the housing. An indicator wheel is disposed in the housing so that a portion of the indicator wheel is visible through the window, wherein pivoting of the shoe member relative to the housing causes the indicator wheel to rotate.

Abstract: A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion.

Abstract: A power tool that includes a housing, a trigger switch that is mounted to the housing, a tool output member and a motor and transmission assembly. The housing defines a handle. The motor and transmission assembly is coupled to the housing and is configured to drive the tool output member. The motor and transmission assembly include a motor, which is electrically coupled to the trigger switch, and a transmission having a transmission input member, which is drivingly coupled to the motor, and a transmission output member that is drivingly coupled to the tool output member. The motor and transmission are packaged in the housing in a manner that is extremely compact.

Abstract: A method of positioning a shoe member and a keel assembly relative to a housing of a jigsaw is provided. The method may include securing the keel assembly to the housing so that the keel assembly extends from the housing beyond the shoe member. The housing and the keel assembly may be pivoted relative to the shoe member in a manner such that a position of the housing relative to the keel assembly remains unchanged. A portion of the keel assembly may be uncoupled from the housing.

Abstract: A jigsaw includes a housing containing a motor activated by a trigger assembly. A shoe member is pivotally connected to the housing of the jigsaw and establishes an angle therebetween. The jigsaw includes a keel assembly includes a blade member that generally extends from the housing beyond the shoe member. The keel assembly remains generally in line with the housing as the angle between the shoe member and the housing varies. The jigsaw also includes a latch assembly capable of retaining and releasing the keel assembly from the housing.

Abstract: A jigsaw generally includes a housing that contains a motor activated by a trigger assembly. A reciprocating shaft is connected to the motor that extends from the housing toward a cutting area. A laser module is contained with a housing operable to produce a laser light pattern forward of the cutting area. An upper connection portion releaseably connects the housing of the laser module to the housing of the jigsaw. A lower connection portion pivotally couples the housing of the laser module to the housing of the jigsaw to permit the housing of the laser module to tilt away from the housing of the jigsaw to provide access to a rear area of the laser module.

Abstract: A fastening tool that drives a fastener into a work-piece. The tool includes a motor that is connected to a transmission. The transmission includes a flywheel. The tool also includes a driver mechanism that is adapted to drive the fastener into the work-piece. The flywheel is connected to the driver mechanism when the flywheel is in a flywheel firing position. The tool includes a control module that detects a flywheel position and compares the flywheel position to the flywheel firing position. The control module also adjusts the flywheel position based on the comparison. The control module ensures that the transmission has enough rotations to ensure that enough momentum can be generated to drive the fastener into the work-piece.

Abstract: An automatic shaft lock is incorporated into the transmission or drive components of a power driving tool of the type commonly used to tighten or loosen threaded fasteners, for example. The automatic shaft lock operates to prevent an externally-applied rotational back-force or back-torque, such as results from use of the tool to manually tighten or loosen a fastener, from being transmitted all the way through the drive components to the tool's motor or armature shaft. The shaft lock also effectively reduces the amount of back-torque, functioning automatically in either rotational direction, due to being disposed at an intermediate location in the drive train, between an intermediate gear enmeshed for driving rotation with the tool's armature shaft and an output gear enmeshed in a driving relationship with the tool's output shaft.
