- FIG. 4 is an enlarged fragmentary front elevational view of the nose section of FIG. 3;
- FIG. 5 is a sectional view taken along line 5-5 of FIG. 4;
- FIG. 6 is an explodedperspective view of the guard piece, the adjustable arms and the outer plate of the nose section of FIG. 4.
- a pneumatically powered fastener-driving tool T which includes a housing 10 having a rearwardly extending handle 11 and a magazine 12 which accommodates a plurality of fasteners F, see FIG. 3.
- a nose section 13 Depending from the underside of the housing is a nose section 13.
- a driver piston mounted for reciprocatory movement within the housing is a driver piston, which includes a depending rod or blade 14. The blade is adapted to engage a fastener and cause the latter to intothe workpiece, not shown.
- a trigger Carried by the handle 11 is a trigger, not shown, which is adapted to be manually actuated.
- a safety mechanism 15 which includes a release rod 16 slidably mounted on the side of the housing. The release rod, when moved upwardly to its fullest extent, enables the manually depressed trigger to be operative causing compressed air to impinge against the driver piston moving same through a drive stroke.
- the operation of the safety mechanism in conjunction with the trigger is well known in the art.
- the nose section 13 includes an inner plate 17 which is fixedly secured tothe end 12a of the magazine 12 by a plurality of bolts 18, see FIG. 4. Plate 17 is provided with a passageway 20 through which the fasteners successively pass from the magazine 12.
- the shape and size of the passageway will depend upon the type of fasteners being driven by the tool.
- the tool is adapted to drive staples, thus the' passageway 20 has an inverted U-shape.
- an outer plate 21, see FIG. 5 which is adapted to cooperate with plate 17 so as to form an elongated guideway 22 which is aligned with and accommodates the portion of the driver blade 14 which projects from the lower end of the housing 10.
- the surface -of the outer plate 21 in contact with the inner plate 17 is provided with an elongated groove 23, see FIG. 6, which extends the full height of the plate.
- the guideway may be formed by a groove formed in the inner plate, or by a pair of complementary'groovesformed in both the inner and outer plates.
- the'shape and size of the guideway 22 will depend upon the type of fastener being driven by the tool T.
- the guard piece 24 is preferably of unitary construction and includes a center section 25 in which are formed a pair of elongated pockets 26 which in the illustrated embodiment constitutes elongated, substantially parallel, vertically extending slots.
- the center section 25 Extending rearwardly from opposite sides of the center section 25 are side flanges 27.
- the inner edges 27a of the flanges are offset and slidably engage the back side of the outer plate 21, see FIG. 5.
- One side of the center section 25 also includes a rearwardly extending finger 28, see FIG. 3 which is adapted to engage the lower end of the trigger-actuating release rod 16.
- the release rod 16 and the guard piece are biased by any suitable means to assume a down position that is to say, the lower end 24a of the guard piece 24 projects beyond the underside of the inner and outer plates 17 and 21, respectively.
- This arrangement constitutes a safety feature requiring that the lower end 24a of the guard piece be pressed against the surface of the workpiece with sufficient force so as to cause the guard piece and in turn the release rod to be pushed upwardly to their fullest extent thereby enablingthe trigger to be operative when it is manually depressed.
- a safety feature is common on many types of powered tools presently available on the market.
- the inner and outer plates 17 and 21 are resiliently held in assembled face-to-face relation by a pair of springlike arms 30 and 31.
- Each arm is of like construction and has an inner end 32 which is offset and extends into a pocket P formed'in the end 12a of the magazine 12.
- the opposide end 33 of the arm 30 or 31 is also offset in the same direction as end 32 and is adapted to overlie the exposed surface of the center section 25 of the guard piece 24, see FIGS. 4 and 5.
- End 33 is further offset so as to form a projection 33a, which is adapted to extend through the corresponding slot 26 formed in the guard piece and resiliently engage the outer plate 21.
- the inner and outer plates 17 and 21 are resiliently clamped together between the ends 32 and 33 of each arm and 31.
- each arm is provided with an enlarged opening 320 through which extendsthe shankof a retaining pin 34 carried by the end 12a of the magazine 12.
- the pin 34 cooperates with the arm end 32 so as to provide a fulcrum about which the arm is adapted to pivot and also the pin prevents the arm from becoming disassembled from the end of the magazine 12, when the arm is in a release position, see FIGS. 2 and 5.
- the enlarged opening 32a in the arm end 32 is oversized relative to the diameter of the pin shank 34 so as to permit the arm to pivot to the release position shown in phantom lines in FIG. 5.
- Movement of the arms to the open positions may be readily accomplished by inserting the end of a screwdriver or the like into-the space S formed between the side of the magazine end portion 12a and a center segment 35 of each arm and then prying the arm segment laterally outwardly.
- a nose section has been provided wherein the components thereof may be readily assembled and disassembled by a simple manual manipulation without requiring special tools.
- the nose section is possessed of self-clearing capabilities and thus, materially reduces the incidents of jamming.
- the nose section is of simple design and yet is capable of automatically preventing serious pressure buildup within the nose section.
- a powered fastener-driving tool having a housing, a fastener-magazine and feed assembly associated with said housing and having a discharge end thereof disposed adjacent the underside of the. housing, a reciprocating driver element mounted within the housing and having an end portion thereof protruding from the underside of the housing; a nose section mountable on the underside of the housing for accommodating the protruding end portion of the driver element and the discharge end of the fastener-magazine and; feed assem bly, said nose section comprising an inner plate fixedly mountable on the discharge end of the fastenermagazine and feed assembly, said inner plate having a passageway through which fasteners intermittently pass from the fastener-magazine and feed assembly, an outer plate disposed in.
- a guard piece carried by said outer plate and substantially overlying the exterior of said outer plate and being slidably movable relative thereto between extended and retracted positions with respect to the underside of the housing, and resilient means adjustably carried on a fixedpart of the tool and adapted to be manually manipulated between first and second positions and, when in the first position, having a portion thereof overlying the exterior of said guard piece, and resiliently engaging and retaining said outer plate in face-to-face relation with said inner plate, and, when in the second position, being disengaged from said outer plate whereby said guard piece and outer plate are'disassembled relative to said inner plate.
- said resilient means comprises a pair of spring-like substantially C- shaped arms having inner ends adapted to be adjustably connected to and disposed on opposite sides of the fastener-magazine and feed assembly,- and outer ends resiliently engaging and overlying corresponding-exterior portions of said outer plate when said resilient means tained in said face-to-face relation.
