An apparatus for driving fastening elements into an underlying surface has a setting duct, an energy transmission element, movable in a fastening direction in the setting duct, for transmitting energy to each of the fastening elements, and a magazine, having a transport duct for transporting the fastening elements in a transporting direction to the setting duct, wherein the magazine comprises a slider, displaceable in the transporting direction along the transport duct and has a feeding element, movable between a transporting position and a passage position, wherein the feeding element projects into the transport duct in the transporting position to apply a force in the transporting direction to the fastening elements, wherein the feeding element opens the transport duct for the fastening elements in the passage position, and wherein the slider has a release spring, the feeding element toward the passage position and is supported on the slider.

A powered fastener driving tool, and particularly a powder-actuated fastener driving tool including a housing assembly partially defining a plurality of pawl leg pockets, a piston assembly and a barrel assembly removably and partially positionable in a receiver assembly that is partially positioned in the housing assembly, and a plurality of attachment pawls including respective legs positioned in respective ones of the pawl leg pockets and configured to maintain the piston assembly and the barrel assembly removably and partially positionable in the receiver assembly.

A fastener driving tool including a housing and a workpiece contact element movably connected to the housing, where the workpiece contact element is movable between a rest position and an activated position. A trigger assembly including a bottom assembly and a top assembly is movably connected to the housing. The tool includes an actuation lever movably connected to the bottom assembly of the trigger assembly and movable between a rest position and an engaged position. The top assembly includes a downwardly extending block configured to engage the actuation lever. A damper mechanism is associated with the actuation lever and is configured to control a rate of movement of the actuation lever.

The invention relates to a fuel-operated firing device for driving securing elements into a substrate, comprising at least one main combustion chamber for a fuel, a driving piston that can be driven out of the main combustion chamber in a firing direction by expandable gases, and a pre-chamber with which an ignition device is associated and in which a pressure acting on the main combustion chamber can build up prior to a fuel-air mixture being ignited in said main combustion chamber. In order to improve the efficacy and/or functionality during the driving in of securing elements, a valve system is associated with the pre-chamber, by which valve system a maximum charge pressure in the pre-chamber can be varied in order to adjust the firing energy provided during the firing operation.

A powered driving tool, such as a nailer, having a magnetic filter in the contact trip that retains ferrous debris remaining in the nosepiece as a result of a first fastener being driven into a workpiece, and allows the ferrous debris to be expelled from the nosepiece with a portion of a second fastener, when the second fastener is driven into a workpiece.

Various embodiments of the present disclosure provide a workpiece-contact element for a fastener pusher. In one embodiment, the workpiece-contact element includes an attachment side, a workpiece-contact surface, and one or more fastener-exit surfaces defining a fastener-exit throughbore having a longitudinal axis and extending through the workpiece-contact surface. The workpiece-contact surface forms an annular protrusion extending away from the attachment side.

A fastening tool having a depth adjustment mechanism mounted on a longitudinally movable door of a nosepiece assembly. The depth adjustment mechanism including a depth adjustment wheel having an internal threaded section extending along an axis and being rotatable about said axis; and an adjustment screw disposed within the depth adjustment wheel and engaging the door plate, the adjustment screw having an external threaded section that engages the internal threaded section of the depth adjustment wheel, so that a rotational movement of the depth adjustment wheel with respect to the adjustment screw effects a relative axial movement of the adjustment screw and the longitudinal movement of the door to increase and decrease the depth that a fastener is driven into a workpiece.

A fixing tool including a nose for guiding of fixing elements and a striking plate for striking of the fixing elements, wherein the fixing tool is configured to fire a fixing element of a first type and a fixing element of a second type with dimensional and/or geometric characteristics which are different from those of the fixing element of the first type.
