  • 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.
