Abstract: A pneumatic nailing mechanism with a housing forming a handle with opposite ends and a longitudinal axis extending therebetween. A cap magazine extends from the housing and is capable of receiving a plurality of stacked caps. A movable shuttle translates a cap from the cap magazine to below the nail driving mechanism for receiving the nail driven by the nail driving mechanism and the stack of caps above the lowest cap is retained within the cap magazine during translation of the shuttle.

Abstract: A cap suitable to receive a fastener for operation with a cap nailer. The cap includes a top surface and a bottom surface and an outer peripheral wall between the top and the bottom surfaces. The outer peripheral wall includes at least one planar surface, which receives an adhering strip that extends along a stack of similar caps to collate the stack of caps together.

Abstract: A chuck for use with a manual or powered driver having a housing and a rotatable drive shaft extending therefrom is provided. The chuck includes a generally cylindrical body member having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face formed on one side thereof and threads formed on the opposite side thereof. A nut is rotatably mounted on the body in engagement with the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A locking member, in a first axial position, is rotatable with respect to the driver housing. In a second axial position, it operatively engages the housing and the nut so that the locking member is rotationally held to the housing and the nut so that the nut is rotationally held to the housing. The locking member is axially reciprocal between the first axial position and the second axial position.

Abstract: A chuck includes a generally cylindrical body and a plurality of jaws reciprocally disposed in the body in communication with a central bore in the body. A first detent extends radially into the central bore and is releasable in a radially outward direction. Upon insertion of an elongated tool shaft having a polygonal cross section into the bore so that a groove in the tool shaft is aligned with the first detent, the first detent engages the groove and axially retains the tool shaft. Upon movement of the jaws so that the jaw faces engage flat sides of the tool shaft, the jaws rotationally retain the tool shaft.

Abstract: A battery ejection mechanism for ejecting a battery housing removably attached to an electrical device housing. The mechanism includes at least one ejection member having a button and an arm. The arm is adapted to transfer a force applied on the button to the electrical device housing to assist in the removal of the battery pack from the electrical device housing. Button motion may also be used to cause retraction of latches mounted on the battery housing.

Abstract: A battery ejection mechanism for ejecting a battery housing removably attached to an electrical device housing. The mechanism includes at least two ejection members, each having a button and an arm. The arms are adapted to transfer a force applied on the buttons to the electrical device housing to provide a pushing force for ejection of the battery pack from the electrical device housing. Force on the buttons also causes associated latches on the battery pack to move to their release position.

Abstract: A tool safety system minimizes the likelihood of injury by detecting when a body part is in close proximity to a moving part of the tool. Upon detecting, a control system can provide one or more of moving the tool, disabling the moving part, or producing a warning signal.

Abstract: A table saw has a movable cutting tool for cutting a workpiece in a cutting region. The table saw includes a detection system to detect one or more conditions between a person and the cutting tool and a retraction system associated with the detection system. The retraction system retracts the cutting tool away from the cutting region independently of the motor and disengages the cutting tool from driving rotation with the motor upon detection of the one or more conditions by the detection system.

Abstract: A table saw such as a chop saw, a miter saw, compound miter saw or a sliding compound miter saw that is provided with a laser arbor alignment system. An opaque shield or transparent shield having an opaque mask blocks the laser beam from being projected into a range of normal operator eye positions. One or more openings in the shield or opaque mask provide a sight line on a workpiece initially. As the saw is moved into engagement with the workpiece, the shield is pivoted away from the workpiece and a solid laser line is projected on the workpiece.
