In a powder driven fastening tool, a channel is included for feeding a strip of explosive powder cartridges to a firing mechanism. A trigger is included for actuating the firing mechanism, wherein the trigger is movable between a first position and a second position. An advancing lever is pivotally coupled to the tool, the advancing lever having a strip engagement portion for indexing the strip which extends into the channel. An advance link is cammingly engaged with the advancing lever and is operationally associated with the trigger so that the strip engagement portion is in a first position in the channel when the trigger is in the first position and so the strip engagement portion is in a second position when the trigger is in the second position.

A powder-actuated tool for driving fasteners, such as drive pins, into concrete, masonry, or steel workpieces comprises a tool body having a sleeve, a barrel extending forwardly from the tool body, a firing pin mounted operatively in the tool body and movable therein between a dormant position and a firing position, and a manually operable trigger for releasably latching the firing pin and for releasing the firing pin when the trigger is actuated with the firing pin in the dormant position. When moved to an actuated position with the firing pin in the dormant position and releasably latched a spring-loading element extending backwardly from the sleeve manually loads a spring compressively, so as to bias the firing pin toward the firing position.

In a fastener driving tool, a retention system for a piston comprises a buffer and a set of bearings in a cage, the bearings being abutted against the buffer. The buffer provides a force urging the bearing radially inwardly toward the piston so that the bearings retain the piston in a predetermined position when the piston is not being actuated.

In a hammer-strikable, powder-actuated, fastener-driving tool, a breech block is mounted within a generally tubular body by several resilient shock absorber structures, each including an elastomeric grommet, an eyelet having a tubular portion surrounded by the grommet and an annular portion, a washer interposed between the annular portion and one end of the grommet, and a screw attaching the breech block to the body. The screw shank extends through the grommet. The screw head bears against the washer. The breech block mounts a firing pin, which is biased backwardly to a normal position, and to which a hammer-strikable button is connected. A barrel, mounted upon the body so as to be axially movable with respect thereto, has an elongate slot. A stud mounted upon the body extends through the slot. A washer disposed around the stud is biased against the barrel so as to impart frictional drag to the barrel.

A powder actuated fastener setting tool including a receiver for receiving a portion of a barrel reciprocatable therein between extended and retracted positions, and a substantially enclosed exhaust baffle disposed between the receiver and a muzzle of the barrel when the barrel is in the retracted position for baffling exhaust discharged from the tool during operation thereof. The tool also includes a spring member disposed between a cap fixedly coupled axially to a muzzle of the barrel and the receiver for biasing the barrel in the extended position, and a mechanism for removing exhaust residue from the powder actuated tool during operation thereof.

A magazine for use with a fastener driving tool comprises a slider and a housing defining a chamber, a follower positioned in the chamber to bias fasteners arranged in a strip, and a longitudinal guide member within the magazine chamber to guide fasteners. The longitudinal guide member comprises two fingers that extend inwardly from the slider and prevent the fastener strip from skewing when inside the magazine chamber.

A fastener-driving tool including a combustion power source configured for powering a driver blade drive system for reciprocal movement of a driver blade relative to a workpiece. The driver blade drive system includes a first portion configured such that the combustion power source linearly drives a driver blade towards the workpiece, and a second portion configured such that the driver blade is rotated relative to the workpiece.
