  • the tool comprises a barrel I threadably or otherwise 'secured at its breech end to a frame plate 2.
  • a breech block 3 is hinged to the :frame plate 2 by a hinge bolt 4 passing through both block and plate axially parallel to the barrel on whichthe breech blockA and frame "plate are capable of relative rotation far enoughto expose the breech end of the barrel.
  • a breech'hook 5 engaged in a closely fitting groove in the breech block 3'and secured to the breech block 3-by any convenient means such as a furnace brazing operation is slidably engageable in a groove 5a in the frame plate.
  • thev hinge pin 4 and thebreech hook 5 provide substantially diametrically opposed members resisting axial separation of the breech block and frame plate -and having ample strength to withstand the forces of discharge of any cartridge which may be used.
  • the frame lplate receives a. ⁇ breech stop"A pin 1 mounted in the 'breech block which limitsv'the swinging movement of the breech block.
  • an action tube cover 8 whichhouses and protects certain elements of an automatic safety device and of the cartridge ejecting system, both to be .the familiar and inexpensive rimiire type of cartridge, conveniently that known'as .32 Long rimfire, although obviously centeriire types and other calibers of rimre types may be used without departing from the invention.
  • the firing pin II is therefore supported in alignment with one edge of the barrel chamber I2.
  • Guidance and support for the firing pin is provided by a bushing I3 supported in the rear wall of the housing and by a bore I4 in the breech block 3, while a coil spring I5 engaged between the bushing I3 and a flange I on the firing pin provides the driving force for the firing pin.
  • a bushing I3 supported in the rear wall of the housing and by a bore I4 in the breech block 3, while a coil spring I5 engaged between the bushing I3 and a flange I on the firing pin provides the driving force for the firing pin.
  • the end of the firing pin is exposed, when cocked, providing for an instantaneous visual check on the readiness of the tool for firing.
  • the end of the firing pin may be coated or inlaid with red or other distinctive color to provide a more obvious warning.
  • the firing pin may be retained in a cocked position by a sear I1 (Figs. l, 3, 4, and 5) swingably supported by a sear screw I8 in the housing and provided with a finger I9 engageable with the forward face ofthe flange I6 on the firing pin I I (Figs. l, 3, 4, and 5).
  • An arm 20 on the sear is extended laterally into a position opposing a cam 2I formed on a slidable trigger bar ⁇ 22.
  • the trigger bar is provided with a finger piece 23 positioned in the grip IIJ and is normally urged forwardly by a spring 24. Obviously, when the trigger is pulled rearwardly, the cam 2
  • the safety cam is provided with an eccentric 1 and serrated, knurled, or toothed surface 2 9 which is opposed to a similarly roughened surface 30 on the trigger bar.
  • the eccentric safety cam is rotated to a point such that the roughened surfaces are l out of engagement.
  • the surfaces 29 and 30 are in engagement and any slight rearward movement of the trigger rotates the cam into closer engagement and positively locks the trigger bar. This locking ger bar and will lock the bar if the safety button is released after the trigger has been pulled almost to the releasing point or at any intermediate. point.
  • reciprocably mounted in the housing and urged by a spring 3Ial to project into a position where it extends across and obstructs the path of'firing pin releasing movement of the sear.

  • a further safety feature is provided by the sear 5 Unless the sear lock is moved rearwardly from the finger 32 into operative engagement with the sear lock. Unless the breech is properly locked, the holes are out of alignment and the sear lock may not be operated by any means. Obviously, the thickness of the action tube finger must be less than the diameter of the sear lock and the finger must be appropriately positioned or the finger will itself act as a sear lock.
  • Operation of the action tube is by means of an action tube extension 36 slidable on the barrel and threadably engaged with the action tube.
  • a spring 31, engaged between a shoulder on the barrel and the action tube extension, normally Vmaintains the action tube in a forward position in which the end of the action tube projects beyond the muzzle of the barrel.
  • the action tube extension When the tool is pressed firmly against the surface of a workpiece, the action tube extension will be telescoped .into the cover until the muzzle of the barrel comes into contact with or, if desired, approaches contact with the work. This telescoping movement is-adequate to bring the finger on the action -tube into engagement with the sear lock and to move the sear lock out of opposition to the sear.
  • the sear lock will return to a safe position even though the trigger is partially pulled at the time.
  • the sear lock spring 3Ia is of substantial force and with Va partially pulled trigger the sear lock returns I direction. It will be noted that the application of force by the operator to disengage the sear lock is in the opposite direction to the force necessary to pull the trigger, thus minimizing the possibility of inadvertent firing.
  • the firing pin is cocked each time the breech is opened by a slide 40 which also has the function of ra breech block latch.
  • the operation of the slide is best understood by reference to Figs. 3 to 45, and 8 to l0.
  • the slide is arranged for sliding movement in .ahgrocve 40a in the back face of the breech block and is slotted at 4I to straddle the firing pin in a location forward ofa cooking flange 42 formed thereon.

  • both the breech face of the barrel and the extractor claw are counterbored to provided a recess completely enclosing and supporting the head of the cartridge to prevent case casualties with high operating pressures.
  • a sabot if a sabot is to fulfill its function as a gas check, it must t tightly in the bore and since tools of this type are designed to be firedr with the muzzle practically in contact with the workpiece, the heel of the fastener and the sabot thereon will usually remain within the muzzle section of the barrel after ring. If'the snug nt between sabot and barrel is retained all the way vto vthe muzzle, it may be diflicult to remove the tool from a driven fastener or the sabot may pull i off the fastener and remain in the barrel, neither condition being desirable.

  • the guard is permanently fastenedto the action tube extension and may not be re ⁇ c moved without unscrewing the action tube extenfA sion from the action tube. This feature prevents the use of the tool without a guard yand thus insures that a careless operator'm'aynot remove the guard and cause his own injuryfrom spall fragments, ricochets, etc.
  • eachV furnished with aspecial guard adapted to the particular job may be furnished as accessories.
  • accessories are not shown in this applica-'- tion, since they function exactly as the standard guard here illustrated and differ only inthe conformationof the work engaging portion offth guard.
