- the barrel assembly includes a barrel member 52 having a bore 54 therein.
- a cartridge receiving chamber 56 is provided at the breech end of the barrel member for the reception of a propellant charge 58.
- the barrel assembly 50 also includes a muzzle bushing 60 which has a bore 62 of lesser diameter than the bore in the barrel member 52 and is threadedly received within the forward end of the barrelmember 52.
- a sheath member 64 surrounds the muzzle end of the barrel member 52 and includes an intumed flange 66 which is positioned between the forward edge 68 of the barrelmember 52 and a shoulder 70 on the external surface of the muzzle bushing 60.
- a piston member 72 may be mounted for reciprocal movement within the barrel assembly 50.
- the piston member 72 includes an enlarged, generally cylindrical head portion 74, the outer surface of which is in sliding relationship with'the bore 54 of the barrel member 52 and a reduced, elongated, cylindrical shank portion 76 extending forwardly from the head portion 74.
- the shank portion 76 includes a tapered portion 78, which tapers down to a portion 79 having a diameter equal to the internal diameter of the muzzle bushing 60.
- the tapered portion 78 is adapted to abut a taper 80 in the rearward end of the muzzle bushing 60 to stop the piston in the event of overdrive thereof.
- the outer surface of the head portion 74 may contain a circumferentially extending groove 81 in which may be mounted a split piston ring 82.
- the outer surface of the head portion 74 is also provided with an axially extending groove 84.
- the piston ring 82 has a portion 85 turned into the head portion 74 so that the piston ring 82 is positioned so that the split thereof is intercepted by the groove 84 whereby communication is provided between the chamber behind the rearward face 86 of the piston upon which the gases act and the chamber in front of the forward face 88 of the head portion 74.
- a sleeve member 90 is mounted within the barrel member 52 and has a forward, outwardly extending flange 92 positioned between the rearward end of the muzzle bushing 60 and a shoulder 94 in the barrel member 52 to hold the sleeve member 90 in place in the tool.
- a rubber O-ring 93 is squeezed between the flange 92 and shoulder 94 which acts as a gas seal and keeps the threads between the muzzle bushing 60 and barrel member 52 clean as well as causing the threads to friction lock to prevent the muzzle bushing from loosening due to vibration.
- the sleeve member 90 has a plurality of gas escape ports 95 which are aligned with gas escape ports 97 in the barrel member 52.
- sheath member 64 has a portion of its rearward edge cut away as indicated at 99 to provide a gas escape path.
- the rearward end of the sleeve 90 has an intumed flange 96 with which the shank portion 76 of the piston member 72 has sliding engagement.
- Both the internal surface of the flange 96 and the external surface of the sleeve adjacent the rearward end thereof have circumferentially extending grooves 98 therein which act as gas seals.
- the outside surface of the barrel member is provided with an axially extending groove 100 which has straight parallel side walls.
- the rearward end of the groove 100 is intersected by a transversely extending groove 102 which also has straight parallel side walls.
- a pawl member 104 is mounted in a housing 106 attached to the tool housing 2 and is spring biased into the groove 100 by means of a spring 108.
- the sides of the portion 109 of the pawl member 104 which extend into the groove 100 are planaras indicated by 110 and 112.
- the rearward side of portion 109 of the pawl member 104 is also planar so that when the barrel member is moved forward relative to the housing, the flat side 1 14 of the pawl member 104 will contact the flat wall of groove 1 02 thereby providing area contact between the two members.
- the width of groove 102 is less than the front to rear dimension of portion 109 of the pawl member 104 to prevent relative rotation of the barrel with respect to the housing when the barrel is in its forward position relative thereto.
- the muzzle bushing 60 has an axially extending slot 116 extending to the internal surface in the forward end thereof.
- a wire spring member 118 has a portion 120 wrapped around the external surface of the muzzle bushing 60 and a bowed'end portion 122 extending into the groove with the how 124 thereof projecting into the interior thereof.
- the spring 118 serves to resiliently hold the washer member 126 which is mounted on the shank portion 128 of a fastener'l30 in place in the muzzle end of the tool.
- FIG. 7 shows the details of the forward or ram end of the piston member 72 which is especiallyconstructed to drive .fasteners such as fastener 130 having a threaded head portion 131 thereon.
- the piston member 72 has a counterbore 132 extending into its forward end.
- the counterbore has an inwardly tapering first portion 134 which tapers from a diameter larger than the external thread diameter to a diameter about equal to the external thread diameter.
- a cylindrical intermediate portion 136 having a diameter equal to or just slightly greater than the external thread diameter of the fastener connects the first portion 134 with a conical inner portion 140.
- the piston member 72 is normally in its forward position as shown in- FIG. 8.
- a fastener such as fastener 130
- the insertion of the fastener 130 into the tool serves to return the piston member 72 to its firing position and also serves to provide ameans for power adjustment.
- the volume of the chamber between the end face 86 of the head portion 74 of the piston member 72 and the cartridge receiving chamber 56 determines the power. level for a given fastening operation. The larger the initial volume of this chamber, the less power is available for a given fastening operation.
- grooves and 102 in the barrel do not extend into the bore 54 thereof.
- the chamber-behind the head portion 74 of the piston, as well as the chamber in front of the head portion 74 is imperforate.
- This has the advantage of v providing a tool which is less noisy than tools wherein such chambers are perforated as by aslot for the reception of a pawl for piston return and barrel guidingfunctions.
- the tool may be moved to its breech open position to expose thecartridge receiving chamber 56 for the insertion of a new cartridge. This is accomplished by pulling the barrel assembly 50 forward relative to the housing 2 until the portion 109 of the pawl member 104 abuts the end of the groove 100.
- a straight wall portion is provided against which the planar face 114 of the pawl member 104 will abut. This provides area contact on both surfaces. This feature reduces burring and peening which might result if one or both of the surfaces were round and presented only line contact.
- the operator To fire the tool, the operator must push down on the housing 2 to move the housing 2 forward relative to the barrel assembly 50. In so doing, the cocking rod 34 abuts the rearward end of the barrel member 52 so that the housing 2 moves forward relative thereto.
- the detent member 30 By virtue of the detent member 30 extending into the opening 40 in the cocking rod 34, the housing 2 also moves forwardly with respect to the firing pin 20 until the forward face of the breech block 16 abuts the rearward surface of the barrel assembly 50.
- the detent member 30 is in operable alignment with the sear portion 44 of the trigger member 42, so that by pulling the trigger member 42, the sear portion 44 will release the detent member 30 from the opening 40 in the cocking rod 34 and the firing pin 20 will fly forward under the action of its spring member 28 until the nose portion 22 thereof projects through the frusto-conical opening 18 in the breech block 16 and actuates the cartridge 58.
- the gases generated by the ignition of the cartridge 58 act upon the rearward face 86 of the piston member 72 to drive the piston member forwardly and in turn drive the fastener into the work surface.
- the piston member 72 moves forward, some of the gases behind the rearward face 86 are bled through groove 84 into the chamber between the forward face88 of the head portion 74 of the piston member 72 and the rearward face of the flange 96 on sleeve member 90.
- the chamber in front of the head portion of the piston is smaller than the chamber behind the rearward face 86.
- the gases trapped in the forward chamber serve to buffer the piston at the end of its stroke.
- the bled gases serve to hold the muzzle bushing of the tool against the work surface.
- This feature coupled with the fact that the forward force of the gas upon the flange 96 of sleeve member 90 in the barrel member tends to negate the rearward force of the gas acting upon the cartridge chamber, reduces recoil of the tool.
- the tapered portion 80 in the muzzle bushing 60 will abut the tapered portion 78 of the piston member 72.
- this tool is designed to fire a fastener from a zero standoff position. That is, from a position wherein the tip of the fastener is substantially flush with the front surface of the muzzle bushing which means that when the tool is applied to a work surface, the fastener tip will be positioned against the work surface.
- the design of the front end of the piston member 72 with the counterbore therein, permits the tool to be used to fasten fasteners having a threaded head portion.
- the tapered portion 134 of the counterbore serves as a guide to insert the threaded head portion into the counterbore, while the cylindrical portion serves to-support the fastener.
- a fastener driving member mounted in said barrel for movement between a driving position and a driven position, said fastener driving member including an enlarged head portion and a reduced elongated ram portion extending forwardly from said head portion;
- said barrel having a cartridge receiving chamber com municating with the interior of said barrel at a point rearward of the head portion of the fastener driving member when said fastener driving member is in the driving position and sleeve means in said barrel having a flange thereon in gas-sealing relationship with the reduced elongated ram portion of said fastener receiving member, said flange defining a portion of said gas chamber.
