A shield subassembly for fastener driving tools is provided that is operable to prevent an interference condition. The shield subassembly includes a rotary-to-linear lifter with lifter pins and a driver with protrusions, and the lifter pins are individually biased so as to be individually retractable and extendable. The lifter is operable to perform a lift stroke in order to raise the driver to a ready position, and then begin a drive stroke to force a fastener into a substrate. The shield subassembly includes a ramp that forces each lifter pin to partially retract so as not cause an interference condition upon contact with a driver protrusion. Once the lifter pin is rotated past the shield and contact ceases, that lifter pin extends and can then slide under a misaligned driver protrusion, or make contact and begin the lift stroke.

A fastener magazine for a fastener driving tool has a movable guide that allows fasteners of various lengths to be loaded in the magazine. When engaged, the movable guide sequentially directs each fastener's movement during a drive stroke. When disengaged, the movable guide does not interfere with each fastener's movement during a drive stroke. In the engaged position, the movable guide prevents a fastener from complete “backtracking” back into the magazine during a drive stoke, which otherwise could potentially cause a jam condition.
A fastener driving tool that uses pressurized gas to drive a piston that causes a driver blade to force a fastener into a workpiece, and then uses an induction coil to “lift” the piston (as an armature) back toward the top, pre-drive position. The pressurized gas is not vented to atmosphere, but is instead re-used for multiple drive cycles. An optional induction coil can have multiple stages. A more preferred induction coil includes multiple stages, in which some of those coil stages extend beyond the end stroke of the piston, past a “ready” position for that piston.

A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

A rotary-to-linear lifter for fastener driving tools is provided that has independently movable lifter pins that lift a driver with driver protrusions during a lift stroke. The lifter includes a central lifter shaft that rotates during a lift stroke, a solenoid that actuates, a plurality of lifter pins, and a lifter base. When the solenoid actuates, the lifter pins protrude from the top of the lifter base, and when not actuated, the lifter pins retract inside the lifter base. Each lifter pin has a set of forward and rearward springs that allow for longitudinal pin movements along the lifter's axis of rotation. If there is interference during a lift stroke, individual lifter pin(s) become blocked, and mostly remain inside the lifter base, until the lifter rotates the affected pin away from the interference. Then that lifter pin will again protrude from the lifter base, ready to engage the driver protrusions.

The connector includes a washer with a flat portion that prevents improper axial rotation of the lever as the lever is actuated, or at any stable position. The flat extension helps guide the lever into pivoting along a longitudinal axis of the attachment. An adjustable bolt adjusts the clamping force, and secures the lever, washer, and clamp together on the autofeed attachment.
A fastener driving tool that includes a lift mechanism for moving the driver from a driven position to a ready position. In one embodiment, the lift mechanism is mounted to a movable pivot arm, and the pivot arm is slightly rotated to allow the driver to drive a fastener; when the driver is to be lifted in a return stroke, the lifter subassembly is moved back into engagement with the driver, and multiple lifter pins contact protrusions in the driver to lift the driver from the driven position to the ready position. In another embodiment, the pivotable lifter floats along the driver, and “releases” from contact only to prevent a jam or otherwise undesirable operating condition involving the driver; otherwise, the lifter remains nested in the tool's guide body during all operating states. A solenoid-operated latch also is provided to prevent the driver from moving downward (for driving a fastener).

A gas spring fastener driving tool, having a cylinder filled with compressed gas that forces a piston/driver through a driving stroke movement; a rotary-to-linear lifter, then moves the piston/driver back to its ready position, preparing the tool for another driving stroke. The driver has protrusions (teeth) along its edges to contact extending pins of the lifter member, for lifting the driver during a return stroke. The driver's movements are detected by position sensors, and the information provided by those position sensors is used to prevent the lifter from impacting against the driver in situations where the driver did not finish its driving stroke in a correct (“in specification”) position. The use of two position sensors allows a Dry Fire diagnostic test to determine if gas pressure in the gas storage chamber is too high, or has become too low.

When the collar is rotated in a predetermined direction, the ramp surface acts to force the movable plate toward the interior, until that movable plate comes into contact into the recessed channel on the screwgun. Once that has occurred, the autofeed attachment will now be locked into place into that recessed channel and behind a protruding flange of the screwgun. The movable plate(s) is positioned between two retainer structures that are spaced-apart from one another, and create a gap through with the at least one movable plate can move during the locking, and later unlocking operations, by twisting the rotatable collar.

A fastener driving tool that includes a lift mechanism for moving the driver from a driven position to a ready position. In one embodiment, the lift mechanism is mounted to a movable pivot arm, and the pivot arm is slightly rotated to allow the driver to drive a fastener; when the driver is to be lifted in a return stroke, the lifter subassembly is moved back into engagement with the driver, and multiple lifter pins contact protrusions in the driver to lift the driver from the driven position to the ready position. In another embodiment, the pivotable lifter floats along the driver, and “releases” from contact only to prevent a jam or otherwise undesirable operating condition involving the driver; otherwise, the lifter remains nested in the tool's guide body during all operating states. A solenoid-operated latch also is provided to prevent the driver from moving downward (for driving a fastener).
A fastener driving tool with a working cylinder and a piston, the piston outer surface having a lubricant-saturated foam material that stores and dispenses lubricant into the piston-cylinder wall interface, thereby increasing the performance and lifespan of the tool. Another embodiment discloses a two-part piston in which the bottom portion is made of metal and absorbs the main mechanical loading forces of the piston drive and return strokes, and the top portion is made of a non-metallic material that has surfaces that act as sliding bearings against the inner wall of the cylinder.

An automated lift machine that feeds strips of staples into an automated stapling machine that can be used in a production line. The lift machine includes a lifter subassembly and a pusher subassembly, and a magazine for holding multiple strips of staples that are stacked on top of one another. A lift fork extends under of the legs of the second staple strip from the bottom, then lifts up all of the stacked staples in the magazine except for the bottom-most staple strip. After that occurs, the pusher forces the bottom-most staple strip from beneath the stacked staples in the magazine, then pushes that strip toward an exit position, into the feeder for the automated stapling machine. The pusher retracts and the lift fork gently lowers the stacked staples in the magazine until they bottom out, after which the lift fork retracts from the stack.

A fastener driving tool that forces air from its variable venting volume beneath the piston of the working cylinder and directs that forced air through passageways and toward an electronic controller and/or an electric motor before being vented to atmosphere, thereby drawing heat away from those components during an operational cycle of the movable piston. When the piston returns to its initial position, environmental air is drawn through the same passageways, again past the electronic controller and/or electric motor, thereby twice cooling these "hot" components during a single operational cycle.

A fastener driving tool that includes a lifter subassembly for moving the driver from a driven position to a ready position. In one embodiment, the lifter is mounted to a movable pivot arm, and if the driver is mispositioned at the beginning of a lifting phase, the lifter can displace a small distance to allow the lifter to move over the driver's protrusions, thereby allowing the lifting phase to continue without causing a jam. A retainer (or "cam follower") is positioned along a rounded cam profile surface of at least one lifter disk to prevent the lifter from displacing during later portions of the lifting phase, or during a transition phase. The lifter includes at least two rotating disks with extending pins to engage driver protrusions. One of the lifter disks can have gear teeth on its perimeter, instead of a cam profile surface.

A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.
An adapter converts a fastener driving tool into an automatic (multiple shots per second) pneumatic fastener driving tool. The adapter has a control valve that automatically moves to direct pressurized air to different passageways in the tool body in a repetitive cyclic manner. More specifically, the adapter has a housing having a plurality of passageways to allow gas flows to pass therethrough, including a speed control passageway, a trigger control passageway, a firing valve control passageway, and a gas pressure source passageway; a control valve movable within a sleeve in said housing, said sleeve including a left and a right gas passageway; at least two of said plurality of passageways being in fluidic communication with said control valve at all times, each of said plurality of passageways extending to predetermined positions along a mating surface of said housing; and a spring positioned within the sleeve.

A gas spring fastener driving tool, having a cylinder filled with compressed gas that forces a piston/driver through a driving stroke movement; a rotary-to-linear lifter, then moves the piston/driver back to its ready position, preparing the tool for another driving stroke. The driver has protrusions (teeth) along its edges to contact extending pins of the lifter member, for lifting the driver during a return stroke. The driver's movements are detected by position sensors, and the information provided by those position sensors is used to prevent the lifter from impacting against the driver in situations where the driver did not finish its driving stroke in a correct ("in specification") position. The use of two position sensors allows a Dry Fire diagnostic test to determine if gas pressure in the gas storage chamber is too high, or has become too low.

A portable hand-held fastener driving tool of the type which tends to keep the driver element better aligned with the head of the fastener while it's being driven. A biasing spring in the fastener track skews the directional path of the fastener as it is being driven, but the biasing spring does not noticeably affect the path of the driver element, thereby compensating for the slight movement of the tool (and driver) due to the tool's recoil. In an alternative embodiment, a magnet is used rather than a biasing spring, to skew the direction of the fastener as it is being shot by the tool.
A clenching adapter for use with automatic nailers tools is provided, which mounts to a nailer tool, and which extends behind a two-layer workpiece and curls the tip of a driven nail on the opposite side of the multiple-layer workpiece. The adapter includes a movable extension link that pivots on a proximal end, due to the action of an air cylinder actuator, and that pivoting motion causes an anvil mounted on its distal end to grasp the opposite (bottom) side of the workpiece, while also positioning the anvil to a location where it intercepts the nail that will be fired through the workpiece by the nailer tool. The anvil mechanism rotates from a “relaxed” position that fits within a gap in the boards of a workpiece, to an actuated “ready” position that receives and curls the nail, for clenching a multi-substrate workpiece. The actuations are automatically sequenced, in one embodiment.

An automatic fastener driving tool, or an attachment, has a narrow front-end profile so that it is capable of driving screws that are in hard-to-reach positions, such as corners or channel members. The slide body subassembly has an extending mechanism, so that the fastener drive elements extend farther away from the main body structure of the tool/attachment, while still providing a stable and rugged overall tool structure to drive larger screws. The "lick-out" dimension is increased without also increasing the length and width of the feed tube.

An automatic fastener driving tool, or an attachment, has an external depth of drive adjustment subassembly that is mounted external to the feed tube housing, yet has a simple adjustment that does not lose its setpoint easily. By placing the depth of drive mechanism outside of the interior areas of the feed tube, the slide body subassembly can be lengthened without increasing the overall length of the feed system. Certain surfaces of slide body subassembly exhibit a dovetail shape, which allows the slide body subassembly to be robustly mounted so that it is capable of operating with long fasteners while also having the nosepiece mounted in an extended position for use with those fasteners.
An attachment is mated to a power screwdriver by use of an adapter that is first fixed onto the screwdriver. The attachment includes an automatic fastener driver that receives a collated strip of fasteners, and drives them into a working surface. The attachment is mated to the adapter; the attachment contains a radial type of mechanical coupling that can be rotated without dismounting the attachment from the power screwdriver. In this manner, the angular orientation between the attachment and the power screwdriver can be changed “on the fly” by the user. This combination allows the user to keep his or her hands at their operating positions throughout this procedure, thereby allowing the user to re-commence using the combination tool quickly after readjusting the operating angle.

An attachment for a portable hand-held screw driving tool is provided for use with collated strips of screws. The front portion of the attachment is movable to a great extent, to thereby allow the tool to drive screws almost directly at the corner of two walls. A front “nose piece” is pressed against one of the walls, which causes the nose piece to move rearward “into” the remainder of the tool, in a “first stage” of movement. A screw is indexed to its drive position, and a drive bit is abutted against the screw head during this first stage. The nose piece is pressed further into the tool, which also causes a “feed tube” to move rearward “into” the remainder of the tool, in a “second stage” of movement, which rotates the screw as it is emplaced into the wall.
