A fastener driving device includes a fastener driver, a magazine for carrying a supply of fasteners to the fastener driver, a spring that moves the fastener driver through a drive stroke, and a motor configured to move the fastener driver through a return stroke. The motor is operable upon completion of the drive stroke, to move the fastener driver partially through the return stroke a predetermined amount to partially pre-compress the spring. The motor is further operable to fully compress the spring after receiving a signal for the drive stroke.

Fastener driving device

A fastener driving device including a housing assembly, a nose assembly connected to the housing assembly, and a magazine for carrying a supply of fasteners that are provided to the nose assembly. The fastener driving device also includes a fastener driver and a spring that moves the fastener driver through a drive stroke. A motor and a coupler mechanism is also provided for moving the fastener driver through a return stroke.

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.

Cordless fastener driving device

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.

A fastener-driving tool includes an integrated function member 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 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.

A fastening device for driving a fastener into a workpiece by effecting multiple blows upon the fastener comprises a housing and a striker assembly movably mounted within the housing. The striker assembly includes a driver assembly adapted to strike the fastener to be driven into the workpiece. A nose assembly is movably mounted on the housing and has a fastener drive track along which the driver assembly and the fastener travel when the fastener is driven into the workpiece. The fastening device has a feed mechanism operatively connected to the nose assembly for mechanically advancing the fastener into the fastener drive track. The fastener drive track has a guide surface adjacent the aperture of the nose assembly to direct the fastener as it is driven into the workpiece. A releasable fastener assembly releasably secures the nose assembly to the housing of the fastening device. A control assembly controls the operation of the fastening device to conserve energy. A coil of collated roofing nails is adapted for use with the fastening device. Each of the nails of the coil of collated roofing nails is coated with a thermoplastic material that serves as a lubricant which facilitates driving of the nails.

A multi-stroke fastening device comprising a housing, a fastener drive track carried by the housing, a striker assembly guide track mounted within the housing, a striker assembly mounted in slidable relation within said guide track, a power drive assembly, and a feed mechanism. The striker assembly includes a driver member constructed and arranged to strike a fastener disposed in the fastener drive track. The striker assembly is constructed and arranged to be moved along the guide track through a plurality of alternating drive strokes and return strokes to effect a plurality of impacts of the driver member upon the fastener in order to drive the fastener into the workpiece. The striker assembly has a substantially constant drive stroke lengths relative to the guide track. The power drive assembly is constructed and arranged to drive the striker assembly to effect the plurality of impacts of the driver member upon the fastener, and the feed mechanism is constructed and arranged to feed successive fasteners into the drive track to be struck by the striker assembly.

Multi-stroke fastening device

The present invention is a power-operated screwdriving device configured to be used with a rotary power source and a supply of screws. The screwdriving device comprises a housing structure constructed and arranged to be engaged with the rotary power source. Structure defines a drive track constructed and arranged to receive a lead screw from the supply of screws. A rotatable screw engaging bit member is constructed and arranged to be engaged with the lead screw from the supply of screws during a screwdriving operation wherein the lead screw is driven into a workpiece. A releasable bit locking assembly is disposed in the housing and constructed and arranged to operatively connect the bit member to the rotary power source to enable the rotary power source to rotate the bit member during the screwdriving operation. The releasable bit locking assembly includes bit locking structure constructed and arranged to lockingly engage the bit member. The rotatable screw engaging bit member is engageable with the lead screw and movable relative to the drive track such that rotation of the bit member and relative movement between the bit member and the drive track drives the lead screw into the workpiece during the screwdriving operation. A manually engageable release structure is disposed exteriorly of the housing structure and operatively connected to the releasable bit locking assembly. The releasable bit locking assembly is manually movable to move the releasable bit locking assembly between (1) a releasably locked position wherein the bit locking structure lockingly engages the bit member and (2) a released position wherein the bit locking structure is moved out of the locking engagement to thereby allow the bit member to be replaced by another rotatable screw engaging bit member.
