Abstract: A light-weight machine gun is made by replacing selected components previously made of steel with interchangeable components made of coated titanium alloy. Several different coatings are used on the components depending on the performance requirements of the component as well as factors related to convenience. The back sight bracket, the side plates, bottom plate and cocking handle guide of the receiver, and the carrying handle rod of the carrying handle assembly, are made of titanium alloy coated with tungsten DLC; the front block, also made of titanium alloy, is coated with a first coating of chrome nitride for resistance to wear resistance and secondarily for high temperature resistance, followed by a second coating of chrome carbo-nitride to provide the appropriate appearance; and the titanium alloy carrying handle bracket of the carrying handle assembly is coated with boron carbide.

Abstract: An adjustable reciprocating saw has the ability to adjust the orientation of the saw blade in relation to the rest of the tool. The saw blade can pivot about two transverse axes, one parallel with and one perpendicular to the reciprocating motion axis of the saw blade. The portions of the saw's housing which rotate relative to one another are attached with a rotating joint comprising a pin and groove design. Rotation locks selectively prevent rotation of the saw blade about each axis. The rotation locks can be released through simply depressing buttons on the saw. A rear internal bearing increases the durability and decreases the size of the saw. A keyless adjustable shoe is mounted to the saw.

Abstract: The present invention is directed to a keyless shoe lock assembly for a reciprocating saw. The keyless shoe lock assembly is capable of engaging and releasing a shoe bracket for the positional adjustment of a shoe relative to a blade clamp of the reciprocating saw. The keyless shoe lock assembly includes a shoe bracket for positional adjustment relative to a lock plate, a pin for alternately engaging and releasing the shoe bracket, and a lever connected to the pin for the rotation therof. The keyless shoe lock assembly may be used to alternately engage and release a shoe bracket without additional hardware.

Abstract: An articulating pusher assembly, disposed within a nail loading assembly, includes an articulating pusher coupled to an adapter, the articulating pusher for engaging a nail. The adapter may be further coupled with a casing which engages a spool assembly to provide a constant pressure on the articulating pusher assembly to advance the nail down the length of the nail loading assembly. The articulating pusher is enabled to accommodate the use of a variety of nail types and collation angles of nail strips within the nail loading assembly.

Abstract: A nail spacing verification assembly is provided which enables the spacing between nails contained in a collated nail strip, the collated nail strip advancing down a nail loading assembly of a nail gun, to be verified before the nail is allowed to advance. A first and second probe are operationally coupled with each other. If nail spacing is correct, the first probe engages the second probe causing both probes to rotate and the nail to pass. If spacing is incorrect, the first probe does not engage the second probe and the nail is hindered from advancing down a nail loading assembly.

Abstract: The present invention is directed to a keyless shoe lock assembly for a reciprocating saw. The keyless shoe lock assembly is capable of engaging and releasing a shoe bracket for the positional adjustment of a shoe relative to a blade clamp of the reciprocating saw. The keyless shoe lock assembly includes a shoe bracket for positional adjustment relative to a lock plate, a pin for alternately engaging and releasing the shoe bracket, and a lever connected to the pin for the rotation thereof. The keyless shoe lock assembly may be used to alternately engage and release a shoe bracket without additional hardware.

Abstract: The present invention generally relates to the field of fasteners and particularly to a portable fastener system. An aspect of the present invention is directed to a fastener system having a reservoir for storing propellant; and, a fastener device connected with the reservoir; wherein the reservoir is configured for storing propellant at a pressure greater than two hundred (200) psi and delivering the propellant to the fastener device.

Abstract: The present invention is directed to a reciprocating saw including a rotating handle. In embodiments of the invention a reciprocating saw includes a motor housing for containing a motor. A linkage is disposed in the motor housing for linearly reciprocating a straight cutting blade connected to the linkage. A rotating handle is pivotally coupled adjacent an end generally opposite the straight blade. Preferably, the handle is a generally D-shaped handle coupled via a series of interlocking ribs/grooves which may be included on the motor housing, on a connector mounted to the motor housing, or the like. Additionally, a securing mechanism is included for locking the handle in predefined orientations with respect to the motor housing.

Abstract: An apparatus which enables a user of a pneumatic tool device, such as a nail gun, to determine the required compressor pressure needed to most effectively utilize the pneumatic tool device and maximize the life of the tool. A compressor pressure indication assembly on a nail gun comprising a nail verification assembly and a readout assembly enables a user to verify the length and/or diameter of the nails to be driven by the nail gun and set the compressor pressure accordingly.
