Pneumatic trim nailer

A fastener driving tool having a work contacting element slidably coupled to a nose-piece, the work contacting element biased to protrude forwardly beyond an end of the nose-piece, and the work contacting element movable relative to the nose-piece to actuate a tool controlling mechanism for enabling and disabling the fastener driving tool, the fastener driving tool comprising:

• a link coupled to the work contacting element, the link having a threaded end portion extending rearwardly away from the tip of the work contacting element and along one side of the nose-piece;
• a bracket coupled to the tool controlling mechanism, the bracket having two spaced apart fingers, each finger having a curved end portion forming a groove across the finger, the grooves across the fingers formed along a common axis, a portion of the link disposed in the grooves of the fingers;
• an adjustment nut disposed about the threaded portion of the link between the fingers of the bracket;
• a resilient ring disposed about the threaded portion of the link, the resilient ring disposed between the adjustment nut and one of the fingers, the resilient ring under compression;
• a washer disposed about the threaded portion of the link, the washer disposed between the resilient ring and one of the fingers, whereby the work contacting element is adjustable upon rotation of the adjustment nut, and the compressed resilient ring prevents unintentional adjustment of the work contacting element.

A fastener driving tool comprising:

• a nose-piece having a backplate hingedly coupled to a frontplate, the backplate pivotable relative to the frontplate between opened configuration and a closed configuration;
• the backplate and frontplate defining a channel therebetween for driving a fastener from an end of the nose-piece into a workpiece when the nose-piece is in the closed configuration, and exposing the channel when the nose-piece is in the opened configuration;
• a first flange protruding from a side of the backplate substantially transverse to the channel, and a second flange protruding from the same side of the frontplate substantially transverse to the channel, the first flange and the second flange in substantially mating relationship when the backplate and the frontplate are in the closed configuration;
• a lever disposed along the side of the nose-piece and movable back and forth relative to the nose-piece, the lever having a back end and an opposing front end disposed toward the end of the nose-piece, the front end having a recess for receiving the first flange and the second flange in substantially mating relationship;
• a compressed spring member acting on the back end of the lever to bias the lever toward the end of the nose-piece where the first flange and the second flange are receivable in the recess of the lever and maintained in substantially mating relationship when the backplate and the frontplate are in the closed configuration,
• the lever movable rearwardly away from the end of the nose-piece against the bias of the compressed spring member to release the first flange and the second flange in substantially mating relationship from the recess of the lever,
• whereby the backplate is pivotable relative to frontplate to the opened configuration when the first flange and the second flange are released from the recess of the lever.

An improved fastener driving tool having a nose-piece with a channel for sequentially receiving individual fasteners from a collated strip of fasteners and for guiding fasteners driven from an aperture of the nose-piece, the improvement comprising:

• a magazine having a channel for receiving the collated strip of fasteners, the magazine having a front end coupled to the nose-piece for sequentially feeding individual fasteners from the channel of the magazine to the channel of the nose-piece,
• the magazine having a first elongated member with a first side wall having a first inner surface, a first front end, a first rear end, a first top edge portion, and a first bottom edge portion,
• the first bottom edge portion of the first elongated member having a recess formed by an outer flange and an inner flange, the recess extending along a length of the first elongated member;
• the magazine having a second elongated member with a second side wall having a second inner surface, a second front end, a second rear end, a second top edge portion, and a second bottom edge portion,
• the second bottom edge portion of the second elongated member having an intermediate flange with an inner surface and an outer surface,
• the first top edge portion of the first elongated member matable with the second top edge portion of the second elongated member, and the intermediate flange of the second bottom edge portion disposeable in the recess formed by the inner flange and the outer flange of the first bottom edge portion, so that the first inner surface of the first side wall faces the second inner surface of the second side wall;
• a tapered member disposeable between the inner surface of the intermediate flange and the inner flange at the front and rear ends of the magazine to urge the outer surface of the intermediate flange into engagement with the outer flange,
• whereby the first inner surface of the first side wall is accurately space relative to the second inner surface of the second side wall to form the channel therebetween in the magazine.
