According to one aspect of the application, a device for driving a fastening element into a substrate has an energy-transfer element for transferring energy to the fastening element. The energy-transfer element can move preferably between a starting position and a setting position, wherein the energy-transfer element is located, before a driving-in procedure, in the starting position and, after the driving-in procedure, in the setting position. According to another aspect of the application, the device comprises a mechanical-energy storage device for storing mechanical energy. The energy-transfer element is then suitable preferably for transferring energy from the mechanical-energy storage device to the fastening element.

A fastener driving apparatus comprises an energy storage means, a drive mechanism, and an anvil assembly. The drive mechanism selectively engages the energy storage means to store potential energy within the energy storage means. After the drive mechanism disengages, potential energy previously stored within the energy storage means impart a force on the anvil assembly to launch the assembly (and incorporated anvil) to drive a fastener. The drive mechanism may comprise a cam for engaging and disengaging the energy storage means. The apparatus may also comprise a nail indexing mechanism for supplying fasteners, which indexing mechanism may also be acted and operated on by the cam. The apparatus may further comprise a gas spring as a return mechanism for returning the anvil assembly to a position after the anvil assembly has separated from the energy storage means.

A tool is provided for applying fasteners to a workpiece. The tool has a housing with a nosepiece, a motor, a drive actuator, a magazine assembly that holds fasteners, and a feed assembly with a feed actuator configured to move a lead fastener into the nosepiece. A driver in the housing is driven by a drive system that is associated with the driver actuator. A controller is connected to the feed actuator and the drive actuator to implement a firing sequence for driving each lead fastener into the workpiece using the driver and feeding the lead fastener into the nosepiece assembly. The actuators may be in the form of solenoids. The controller is designed to energize and deenergize the motor selectively while the drive actuator and feed actuator are activated.

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 powered fastener driver includes a housing, a nosepiece extending from the housing, a driver blade movable within the nosepiece between a ready position and a driven position the driver blade comprising a plurality of drive teeth on a first side of the driver blade and a plurality of locking projections on a second side of the driver blade, a piston coupled to the driver blade for movement therewith, a driver cylinder within which the piston is movable, a storage chamber cylinder containing pressurized gas therein and in fluid communication with the driver cylinder, a first end of the driver cylinder being affixed to a corresponding first end of the storage chamber cylinder, and a latch actuator assembly adjacent the driver blade, wherein the latch actuator assembly includes a latch to engage one of the plurality of locking projections to prevent the driver blade from moving toward the driven position.

An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.

A powered fastener driver comprising, a housing including a head portion, a handle portion extending therefrom, the handle portion including a first end coupled with the head portion and an opposite, second end, and a drive unit portion, and a canister magazine configured to receive coiled fasteners. At least a portion of the canister magazine is integrally formed as a single piece with at least a portion of the drive unit portion of the housing.

A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, a canister magazine, and a pusher mechanism coupled to the nosepiece. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a first side of a fastener within the fastener driver channel. The lockout lever is configured to engage an opposite, second side of the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.

A powered fastener driver includes a housing, a nosepiece coupled to the housing and extending therefrom, a driver blade, a canister magazine coupled to the nosepiece, a pusher mechanism coupled to the nosepiece, and a cam. The pusher mechanism includes a body coupled to the nosepiece, a feeder arm pivotably coupled to the body, and a lever pivotably coupled to the nosepiece. The lever has a first end that is engageable with the body for imparting reciprocating translation to the body relative to the nosepiece in response to pivoting movement of the lever in opposite directions about the pivot axis. A cam is engaged with a second end of the lever for imparting pivoting movement to the lever. The feeder arm is engageable with individual fasteners in the nosepiece for sequentially pushing the fasteners into the driver channel in response to reciprocation of the body relative to the nosepiece.

A separating device for separating a fastening element from a fastening element strip is provided, having a receptacle, in which the fastening element is received, wherein the fastening element defines a fastening direction, in which the fastening element is provided for being driven into an underlying surface; a transfer channel for transfer of the fastening element strip in a transfer direction, wherein the transfer channel has a separating section; a stop element, which has a stop position, in which the stop element projects into the transfer channel and forms a stop for the fastening element in the transfer direction when the fastening element is arranged in the separating section; and a passage position, in which the stop element is arranged outside the transfer channel and allows movement of the fastening element beyond the separating section in the transfer direction.
