Definitions
- the tool embodies an elongated reciprocating driver blade having a portion thereof embraced by a guide means.
- a nose section depends from the underside of a housing and has adjustably mounted thereon safety means whereby the driver blade cannot move through a driving stroke unless the safety means exerts a predetermined force against the work piece into which a fastener is to be driven.
- a cartridge of collated fasteners is removably mounted on the nose section.
- Fastener feed means is adjustably mounted on the nose section and is operatively connected to said cartridge for successively feeding fasteners into the paths of movement of the driver blade prior to the latter initiating its driving stroke.
- a pneumatically powered fastener-driving tool which includes a reciprocating driving blade of thin cross-sectional configuration having an elongated reinforcing rib formed on at least one surface thereof.
- a guide means for the driving blade is provided which is disposed on the underside of the tool and is adapted to completely embrace a portion of the reciprocating driving blade and be in sliding engagement therewith.
- the driver blade is connected to and movable with a piston which, upon reaching the end of its driving stroke, engages a fixedly mounted bumper piece which dampens the kinetic energy possessed by the piston.
- the bumber piece has a doughnut-like shape with a portion of the driving blade extending through the center of the piece.
- the outer periphery of the bumper piece has an upwardly and outwardly tapered fluted configuration.
- the flutes of the bumper piece extend the full height of the tapered periphery and, thus, effectively dissipate the heat which might otherwise be absorbed by the piece due to the repeated impacts from the driver piston.
- a safety mechanism is embodied in the tool which prevents initial actuation of the piston through its driving stroke unless one end of the safety mechanism is exerting a predetermined force upon the work piece into which the fastener is to be driven.
- the safety mechanism is provided with a spring for positively biasing the safety mechanism into a position wherein the drive piston will remain in a static condition.
- FIG. 1 is a perspective view of the discharge end of one form of the improved fastener-driving tool
- FIG. 2 is a bottom plan view of the tool shown in FIG.

- FIG. 7 is an enlarged fragmentary exploded perspective view of the fastener-feeding mechanism embodied in the tool of FIG. 1;
- FIG. 8 is an enlarged cross-sectional view of one form of the driver blade utilized in the illustrated tool.
- FIGS. 9-11 are fragmentary vertical sectional views showing, respectively, the drive piston in a static position; at a position wherein the piston is disposed at the end of its drive stroke, and the piston returning to its static position;
- FIG. 12 is an enlarged perspective view of one form of the bumper piece utilized in the tool of FIG. 1.
- the tool includes an elongated housing 21, a laterally extending hollow handle 22, a trigger mechanism 23 mounted on the underside of the handle, a nose section 24 depending from the lower end of the housing, a fastener-feed mechanism 25 mounted on and extending laterally from said nose section; and a cartridge 26 of collated fasteners F, the latter being formed into a tightly wound coil.
- Housing 21 as seen in FIGS. 9-11 is provided with an internal upwardly extending cylinder 27.
- the upper end of the cylinder is closed by a poppet valve 28.
- the poppet valve is contained within a cap 30 which is removably mounted on the upper end of the housing 211.
- the housing and cap cooperate with one another to provide a low profile as compared to prior tools of this general type and, thus, facilitate manual manipulation of the tool.
- the cylinder 27 has a relatively large bore (e.g. 1.607 inch diam. upper section; 1.500 inch diam. lower section).
- a spool-type piston 31 mounted for reciprocatory movement within the cylinder 27 is a spool-type piston 31, see FIGS. 911.
- the upper and lower flanges 31a and 31b, respectively, of the piston carry peripheral O-ring seals which are in sliding engagement with the interior surface of the cylinder.
- the upper flange 31a is of greater diameter than the lower flange 31b and, thus, enables the piston 31 to readily return to its static position I, (FIG. 9), once it has reached the terminus II, (FIG. 10) of its drive stroke.
- the movement of the drive piston 31 will be described more fully hereinafter.
- the upper and lower flanges of the piston are interconnected by a stem portion 31c.
- the piston 31 is relatively heavy and, thus, is capable of substantial kinetic energy.
- driver blade 32 Carried on the underside of the piston and depending therefrom is an elongated driver blade 32 which, during movement of the piston through the drive stroke, will engage the trailing end of the fastener when the latter is disposed within a firing station S formed in the nose section 24.
- the downwardly moving driver blade will cause the engaged fastener to be separated from the remaining collated fasteners and be discharged from the tool into the desired work piece, not shown.
- the driver blade 32 has a relatively flat cross-sectional configuration as seen in FIG. 8.
- the outwardly disposed surface of the blade 32 is provided with an elongated narrow rib 32a.
- the portions 32b of the blade surface disposed on opposite sides of the rib 32a converged downwardly a slight amount.
- the lateral end limits of the blade cross-section will remain as thick or thicker than the center portion of the blade which includes the rib.
- the blade will be possessed of greater strength and can be more readily supported during the drive stroke of the piston 31.
- a bumper piece 33 Disposed within the cylinder interior and adjacent I the lower end thereof is a bumper piece 33, see FIGS.
- the bumper piece is preferably of molded one-piece construction and is formed of a suitable resilient material capable of withstanding repeated impacts and high temperatures.
- the bumper piece has a modified doughnut-like configuration with a center hole 33a through which the driver blade extends.
- the exterior annular side wall 33b of the piece is fluted and tapered so that the top surface 330 is of greater dimension that the bottom surface 33d. It will be noted in FIG. 12 that the flutes 33e are symmetrically arranged and extend the full height of the piece. The flutes permit air flow to occur about the piece as the piston reciprocates and, thus, provide an effective means for dissipating the heat which might otherwise build up within the piece, especially when the tool is operated for prolong periods of time.
- the bumper piece 33 is disposed within a tapered seat T which is formed within a removable bottom section 210 comprising the housing and, thus, facilitates replacement. of the bumper piece when necessary.
- Bottom section 21a is provided with an enlarged central opening 21b which is'coaxially aligned with the hole 330 in the bumper piece.
- the opening 21b provides a continuous vent to the atmosphere for the lower interior portion of the cylinder 27.
- the nose section 24 includes a depending member 34 which is fixedly secured to the lower end of the housing 21.
- One side of member 34 isprovided with an elongated channel-shaped passageway 34a through which moves the protruding portion of the driver blade 32.
- a front plate 35 Removably mounted on the depending member 34 so as to overlie the open side of the channel-shaped passageway 34a is a front plate 35, see FIG. 6.
- the plate 35 is provided with an elongated central portion 35a having the surface thereof facing the passageway 34a, contoured so as to substantially conform to the ribbed surface of the driver blade 32.
- passageway 34a and the central portion 35a of front plate 35 coact with one another to form a guide which completely encompasses the portion of blade 32 which projects out through the opening 21b during reciprocatory movement of the drive piston 31. Because of the front plate central portion 35a and the passageway 34a encompassing the projecting blade portion, effective support for the reciprocating blade is maintained, thereby materially reducing the incidents of blade failure.
- the thin blade oftentimes would break or become bent, thereby requiring replacement.
- the front plate 35 is also provided with a pair of lateral extensions 35b.
- the distal ends of the extensions 35b are provided with open-end slots 350 through which assembly bolts 36 are adapted to pass.
- the slots permit a slight adjustment of the plate with respect to the member 34 so that the guide will be properly aligned with the protruding blade portion.
- a safety yoke 38 Positioned outwardly of the front plate 35 is the lower section 37 of a safety yoke 38 which will be described hereinafter.
- a retainer and guide unit 40 for said section.
- the unit 40 is provided with an elongated channel-shaped central portion 40a.
- the central portion 40a is provided with an elongated slot 40b.
- Unit 40 also includes laterally extending shoulders 40c which are adapted to be aligned with and overlie the corresponding extensions 35b of the front plate 35. Suitable openings 40d are formed in the shoulders 40c so as to accommodate the shanks of the assembly bolts 36.
- Nose section 24 also includes a rearwardly extending hollow projection 41.
- the projection is offset with respect to the path of movement of the driver blade 32 and has pivotally mounted on the outer end thereof a clasp 42.
- the clasp cooperates with a flexible band 43 which is attached at one end to the depending member 34, see FIG. 6.
- the free end 430 of the band is hookshaped and is adapted to interlock with an adjustable loop 42a carried by the clasp 42.
- the band 43 when interlocked with the clasp 42, snugly embraces the exterior of cartridge 26 when the latter is assembled on the nose section 24, see FIG. 1.
- the clasp 42 is manually adjustable to lock or unlock positions.
- the cartridge 26 may be of a type similar to that described in US Pat. No. 3,009,6l8 and is provided with a tangentially extending rail section 26a through which the web of collated fasteners passes when unwound from the coil contained within the cartridge.
- the rail section 26a communicates with the infeed side of the firing station S formed in the depending member 34.
- the axis of the coil contained within the cartridge 26 is disposed substantially parallel to the path of movement of the driver blade 32.
- the hollow projection 41 includes a piston 44 mounted within a cylinder 45; said piston and cylinder comprising components of the fastener-feeding mechanism 25.
- the function of the mechanism is to advance the web of collated fasteners F a predetermined amount as the driver moves towards the static position I, thereby enabling the leading fastener to be loaded into the firing station S.
- the forward end of piston 44 is provided with a suitable pusher head 44a which at the appropriate time period will engage and move the feed fingers of the cartridge 26, the latter being of a type similar to that described in US Pat. No. 3,009,618, and then move the web of collated fasteners.
- the rear end of the piston 44 is disposed within the cylinder 45 and is engaged by a coil spring 47 so that the piston 44 is spring-biased to assume an extended position as shown in FIG. 9.
- the piston 44 overcomes the bias of spring 47 only when the pneumatic force is applied to the forward end of the piston 44. This condition occurs when the driver piston 31 has reached a position during the drive stroke wherein a first set of openings 48 formed in the wall of the drive cylinder 27 is uncovered and communicates with the set of openings 51 through the space formed between the flanges of the piston, see FIG. 10.
- the openings 48 are in communication with a conduit 50 which interconnects the interior of the housing 21 with the interior of cylinder 45.
- a second set of openings 51 is also formed in the drive cylinder wall, and each opening thereof is continuously in communication with a cavity 52 formed in the hollow handle 22.
- the cavity 52 is always charged with pneumatic pressure when the outer end of the handle is connected to an air hose, not shown, leading to a source of pneumatic pressure.
- the second set of openings 51 is located so that regardless of the relative position of the piston within the cylinder 27, each of said openings is always in communication with the space separating the flanges 3la and 31b of drive piston 31. Because of the dimensional differential between flanges 31a and 31b, there is always a bias exerted by pneumatic pressure on the drive piston 31 urging the latter to assume static position I.
- the conduit 50 which interconnects the interior of housing 21 with cylinder 45 is shown more clearly in exploded relation in FIG. 7.
- the conduit 50 in the illustrated embodiment consists of a tube 54 having a side opening at the upper end and provided with a mounting bracket 55. The side opening is aligned with an opening in the bracket which, in turn, is in communication with the first set of openings 48 formed in the cylinder wall 27.
- the lower end of the tube 54 is open and has an exterior of reduced diameter.
- the lower end is provided with a peripheral groove 54a which accommodates an O-ring seal 56.
- the lower end of tube 54 is disposed in a substantially free floating relation within an upwardly facing opening 57 formed adjacent the inner end of projection 41.
- the O- ring seal 56 sealingly engages the wall of opening 57. Notwithstanding the severe vibrations to which the tool is subjected during normal operation, the seal connection between the lower end of tube 54 and the opening 57 will be maintained.
- the lower end of opening 57 communicates with the inner end of cylinder 45, see FIGS. 9-11.
- the walls of cylinders 27 and 45 with a material having a very low coefficient of friction (e.g., polyfluro and polyflurohalo-olefins, such as polytetrafluoroethylene, polychlorotrifluoroethylene, etc., sold under such tradenames as Teflon, Tufware, and Kel-F). Because of the aforesaid coating, the tool may be effectively operated at lower pneumatic pressures with the result that the operational life of the tool will be substantially extended.
- a material having a very low coefficient of friction e.g., polyfluro and polyflurohalo-olefins, such as polytetrafluoroethylene, polychlorotrifluoroethylene, etc., sold under such tradenames as Teflon, Tufware, and Kel-F.
- the safety mechanism 38 embodied in the illustrated tool includes not only the lower safety yoke 37, and retainer and guide unit but also an upper safety yoke 58, which is independent of the lower yoke.
- the upper yoke 58 as seen in FIGS. 35, is of one piece construction and has an elongated distorted central portion 58a which is provided with an elongated longitudinally extending slot 58b through which a guide pin 59 extends.
- the upper end 58c of the yoke is laterally offset so as to engage a lever 23a forming a part of the trigger mechanism 23.
- the lower end 58d of yoke 58 extends through an opening formed in a bracket 60, the latter being affixed to the front side of the nose section 24, see FIG. 1.
- the portion of the lower end 58d, which depends from bracket 60, is embraced by a coil spring 61.
- the upper end of the spring engages the bracket 60 and the lower end of the spring engages a collar 37a formed on lower yoke 37.
- Collar 37a is provided with an opening 37b through which the terminus of lower end 58d slidably extends.
- the lower end 58d is of reduced diameter.
- Spring 61 exerts a downward bias on the lower yoke 37.
- Yoke 37 is provided with a curved center portion 37c which interconnects collar 370 with a tongue 37d.
- the center portion 37c extends through the slot 40b formed in the retainer and guide unit 40.
- the lower end of tongue 37d normally extends downwardly from unit 40, see FIG. 5, and when the tool is to be operated is brought into contact with the surface of the work piece, not shown, into which the fastener is to be driven.
- the tongue 37d must be retracted into retainer and guide unit 40 before the trigger mechanism 23 will be operative.
- the trigger mechanism 23 includes a valve piece 62 which is slidably disposed within a sleeve member 63.
- the sleeve member is mounted on the underside of handle 22 and the upper end of the sleeve member has a restricted opening 63a which communicates with the chamber 52 formed in the handle.
- a peripheral passageway 63b At approximately mid-length of member 63 is a peripheral passageway 63b which, in turn, communicates with an internal passageway 64 formed in housing 21.
- the valve piece 62 is biased in a down position by a coil spring 65, which is disposed within sleeve member 63 between the upper end of the valve piece and the upper end of the sleeve member.
- the lower end of the valve piece 62 is fluted and normally projects downwardly from the lower end of the sleeve member 63 and engages the lever 23a of the trigger mechanism 23.
- the combined tensions of spring 65 and spring 61 must be overcome when the tongue 37d is retracted into the nose section in order that the trigger mechanism will be operative.
- the upper offset end 58c of the upper yoke 58 when in its down position, as seen in FIGS. 3 and 4, will engage an offset lip formed on lever 23a and prevent the lever from being manually pivoted in a clockwise direction about pin 66.
- the collar 37a of the lower yoke 37 will engage a shoulder 37e (see FIGS. 3 and 5) causing the upper yoke 58 to move upwardly and, thus, release the lever 23a.
- passageway 64 When the valve piece 62 is in its inoperative or down position, as seen in FIG. 9, the passageway 64 is charged with the pneumatic pressure accumulated in chamber 52 of the handle.
- the upper end of passageway 64 communicates with a cavity 67 formed in the interior of cap 30.
- the poppet valve 28 is slidably mounted within cavity 67 and when passageway 64 is charged with pneumatic pressure, the poppet valve will be held in a down or closed position with respect to the upper end of cylinder 27.
- the poppet valve 28 is normally biased in the closed position by a spring 68.
- valve 28 which permits the portion of the cylinder 27, disposed above the flange 31a of the drive piston 31, to be vented to the atmosphere through an opening 30a when the poppet valve is in its down position with respect to the upper end of the cylinder.
- valve piece 62 When valve piece 62 is manually moved upwardly relative to sleeve member 63, communication between the chamber 52 and passageway 64 is blocked, and because of the fluted lower end portion of the piece 62, passageway 64 is vented to the atmosphere.
- cavity 67 of cap 30 Once cavity 67 of cap 30 has been vented to the atmosphere by passageway 64, the poppet valve 28 will be moved upwardly off the upper end of cylinder 27, as seen in FIG. 10. Upward movement of the poppet valve 28 is effected by the pneumatic pressure within chamber 52 being exerted on the underside of the outer periphery 28b of the poppet valve which projects laterally beyond the upper end of the cylinder 27.
- the pneumatic pressure exerted on the underside of peripheral portion 28b overcomes the bias of spring 68.
- the openings 48 formed in the cylinder wall 27 are in communication with the space between the piston flanges 31a and 3112 which has previously been charged with pneumatic pressure through the openings 51.
- the passageway within conduit 50 and the right hand side of fastener-feed cylinder 45 are charged with the pneumatic pressure thereby causing feed piston 44 within cylinder 45 to move to the left, as seen in FIG. 10.
- a pneumatically powered fastener-driving tool which has a low profile, can operate effectively on lower pneumatic pressure, is less susceptible to breakdown, and is provided with an effective fool-proof safety mechanism.
- a pneumatically powered low profile fastenerdriving tool comprising a housing provided with a cylinder adapted to have the upper end thereof normally closed by an adjustably mounted poppet valve; manually operable trigger means mounted on said housing for controlling the movement of the poppet valve to an open position relative to the upper end of said cylinder; a drive piston mounted for reciprocatory movement within said cylinder and carrying an elongated depending driver blade, the latter having a portion thereof protruding from the underside of said housing, said piston normally assuming a static position adjacent the upper end of said cylinder when said trigger means is at rest and said poppet valve is in a closed position, said piston moving through a drive stroke only when said trigger means is manually manipulated causing the poppet valve to assume an open position; a nose section mounted on and protruding from the underside of said housing, said nose section including a sectional guide means encompassing the driver blade protruding portion; safety means adjustably mounted on said nose section for movement between extended and retracted positions, said safety means, when in a
