Abstract:
In an embodiment of the present invention, a reinforcement bar fastener (rebar fastener) has a substantially T -shaped body with an upper horizontal portion that forms a crossbar between and is integral with a lower pair of legs. In an embodiment of the present invention, there is a fastening tool for applying a driving force to the reinforcement bar fastener to bend the fastener around rebar members to secure the rebar members to each other. The fastening tool can have a body including a driver that provides a downward force on the crossbar portion of the rebar fastener while retractable anvil arms bend the lower vertical leg portions of the rebar fastener upward around the arranged rebar members.
Abstract:
A driving tool with tool portion and a gas delivery system. The tool portion includes a linear pneumatic motor that is configured to propel a driver blade. The gas delivery system is configured to deliver a pressurized gas, such as compressed air or nitrogen, to the tool portion for use in operating the linear pneumatic motor. The gas delivery system includes a first inlet, which is connectable to a first source of compressed gas, such as a stationary air compressor, a second inlet, which is connectable to a second source of compressed gas, such as a tank mounted to the tool portion, and a directional valve for selecting between the first and second inlets.
Abstract:
A fastener-driving tool (10) includes an integrated function member (50) that performs at least two of the following three functions: a check pawl function, a last fastener-retaining function, and a dry fire lock-out function. In the disclosed embodiment, the integrated function member is provided as a lever-type structure that constitutes part of the access door assembly by means of which access is gained to the fastener drive track (31) along which fasteners (e.g., roofing nails) are fed to the driving portion of the tool. Also disclosed is an improved method of retaining the last nail in the drive track by a lateral head gripping action and a tool for performing the method.
Abstract:
A fastener driving device is disclosed. The device includes a housing assembly, and a nose assembly connected to the housing assembly. The device also includes a magazine for carrying a supply of fasteners that are provided to the nose assembly, a fastener driver, and a spring that moves the fastener driver through a drive stroke. The spring includes a composite material. The device also includes a motor for moving the fastener driver through a return stroke.
Abstract:
A fastener driving tool (10) includes a housing assembly (12) with a nosepiece assembly (18) defining a drive track (28). A safety trip assembly (60) includes a trigger enabling portion (62) and a workpiece engaging portion (64) and is movable between an extended disabling position and a retracted enabling position. The safety trip assembly (60) is biased toward the extended position and is moved toward the retracted position by engagement between a workpiece and the workpiece engaging portion (64). The workpiece engaging portion (64) is movable to permit adjustment of a length of the safety trip assembly (60). The workpiece engaging portion (64) may be removed from the safety trip assembly (60) and exchanged with another different workpiece engaging portion (64). A workpiece engaging portion (64) usable with the fastener driving tool (10) includes a positioning mechanism having an opening locating structure (61) and a guiding structure (65).
Abstract:
A power tool (10) for driving fasteners (12), in particular a clip applicator tool, is provided is that includes rear housing and forward head portions (24) with a piston (20) in the rear housing and a fastener driver (18) in the head portion. The rear housing preferably includes a cap member (44) and a housing member (32) with movement of a fluid admission valve (42) split between both to keep size of the cap member to a minimum. Further, guide surfaces for the fluid admission valve member can be integrated into the cap and housing members to avoid having a separate valve body therefor. The forward head portion has light weight outer walls and at least one high strength bearing insert (114) for taking the high loads generated by the tool drive assembly including the driver thereof. In one preferred form, the tool employs both the above-described rear cylinder and forward head portions to provide a balanced, light weight hand-held tool that is ergonomical to use.
Abstract:
A fastener-driving device includes a trigger assembly (12) operatively disposed between a contact trip assembly (30) and an actuating assembly. The trigger assembly includes a trigger member (32), an actuating member (36), and an automatic mode selecting mechanism (48). The mode selecting mechanism includes a mode selecting member (56) having a connection with the actuating member (46) to make the mode selecting member (A) move with the actuating member between first and second positions of the actuating member, and (B) have relative movement with respect to the actuating member (46) so that the mode selecting mechanism (48) retains the actuating member in the first position in response to an initial movement of the trigger member (32) to the operative position, and (b) retains the actuating member in the second position in response to an initial movement of the contact trip assembly (30) into the operative position and a subsequent movement of the trigger member into the operative position.
Abstract:
A pallet having wooden boards secured together by nails which achieve approved operating characteristics. The nail is embodied in a package secured together by a pair of parallel wires welded to the shanks. Each nail having a shank diameter between .092 in. and .148 in., each nail is manufactured from steel wire and has a length between 1.625 in. and 3 in. The ratio of the head diameter to the shank diameter of each nail is between 2.70 and 3.37.
Abstract:
A fastener driving device includes various interconnected systems within a device housing for efficiently regulating and transferring compressed gas provided by user-replaceable cartridges to drive a fastener securely into a workpiece. An improved cartridge containment system is provided for loading and securing compressed gas cartridges. An improved gas management system is provided, including an improved multi-function regulator, for managing gas flow. An improved valve system is provided for controlling gas flow, including an improved valve module. An improved drive system is provided for efficiently using compressed gas to drive fasteners.
Abstract:
The present invention provides a nail (10) suitable for sheathing which provides an enhanced resistance to failure. The nail (10) includes an enlarged head (20) as well as a shank (24) having surface deformations (28). Sheathing panels (40) are secured to a framing structure (42) through the use of the nail (10). The enlarged head (20) provides a first clamping surface that is seated against an exterior surface of the sheathing panel (40). The framing structure within which the shank is secured is a second clamping surface. Through the provision of an enlarged head and a shank having surface deformations, the ability of the nail to maintain the securement of the sheathing panel to the framing structure element is enhanced. A plurality of the nails are disposed within a package (100) suitable for use with mechanical drivers.
