  • FIGURE 8 is a similar view of a modified construc- 3,286,899 Patented Nov. 22, 1966 ICE tion showing the cartridge supported in a driver for the stud;
  • FIGURE 9 is a similar view of a modified construction having mechanism vfor adjusting a driver to accommodate studs of different lengths;
  • FIGURE 10 is a view similar to FIGURE 9 showing the hand grip moved relative to the guide tube to a firing position
  • FIGURE 11 is a view similar to FIGURES 9 and 10 showing the relationship of the parts after tiring and the movement of the recoil mechanism to eject an empty shell into a receiver.
  • FIGURES 1 to 4 illustrate the subject matter of the invention schematically.
  • the breech block 1a is in the form of a sleeve and incorporated in the hand grip 1 and is mounted for sliding movement along the guide tube 2 through which a stud is driven.
  • the cartridge chamber 3 is located in the guide tube 2 and into which a cartridge 4 is introduced from the side.
  • the cartridge chamber 3 is so located along the guide tube 2 that the gas pressure produced by combustion of the explosive propellant acts on the movable piston 5 and the damping mass of a recoil mechanism 6.
  • the bottom of the cartridge 4 bears against the breech block formed as a part of the grip 1 in the particular embodiment to oppose movement of the cartridge.
  • the closing of the breech can be effected after introduction of the cartridge 4 by sliding the grip 1 longitudinally of the guide tube 2 -until it engages the stop 7.
  • the part 5 to 'be driven which can be a stud or nail
  • the tool is ready for tiring.
  • the explosion gases may act directly on the part to be driven as in the case of a gun or indirectly through a thrust piston'which is arranged as power-transmitting element between the stud and the combustion chamber.
  • the tiring mechanism including the firing pin 8 is shown arranged in the hand grip 1.
  • the position of the cartridge chamber 3 with its axis oblique and preferably at right angles to the axis of the barrel is also to be considered a preferred arrangement.
  • At least part of the tiring mechanism including also the tiring pin 8, can be arranged in the guide tube as shown in FIGURE 3.
  • the axis of movement of the breech block and grip on which it is mounted should coincide with or be parallel to the axis of the barrel.
  • FIGS. 4-7 Another embodiment of the invention is shown in FIGS. 4-7.
  • the cartridge chamber 3 is arranged in the recoil mechanism 6, and the housing 2 has a slot 9 overlying the cartridge chamber.
  • the breech block 10 (a part of the grip 1) is also movable relative to the housing 2 and preferably in a direction parallel to the axis of the barrel.
  • the breech block 10 projects into the slot 9 of the housing 2 in such a manner that after longitudinal displacement has 'been effected the cartridge chamber 3 is completely closed off.
  • the entire firing mechanism, including the tiring pin 8 is preferably arranged in the breech block 10.
  • the breech block contains a receiver 11, into which the cartridge 4 is ejected after the shot.
  • FIGS. 1-7 The advantages produced Iby the driving tool in accordance with the invention can be noted from the drawings (FIGS. 1-7).
  • the fastening element l (not shown) can be introduced into the barrel or guide tube 2 from the front thereof and the cartridge 4 can be introduced into the tool from the side.
  • the car tridge chamber When the tool is to be red to drive a stud, the car tridge chamber?) is closed by longitudinal displacement of the grip 1 and breech block thereofwhereby the tool is made ready to shoot.
  • the fastening element (not shown) is inserted from the front into the barrel and a cartridge 4 is introduced into the open cartridge chamber from the side.
  • the cartridge chamber 3 is closed and thus the tool is made ready to fire by longitudinal displacement of the grip 1 on which the breech block 10 is located.
  • the gas pressure produced upon combustion of the propellant drives the element 5 in the 4direction of the muzzle of the barrel and .the recoil mechanism 6 is driven in the opposite direction.
  • the actuation of the recoil mechanism 6 moves the cartridge chamber 3 into alignment with the receiver 11 and the empty cartridge shell is forced into the receiver by the residual gas pressure in the combustion chamber.
  • the cartridge chamber 3 is located in the movable piston 5.
  • the piston'S has a stepped-down section 12 and in the end thereof there is a suitable recess (not shown) to receive an anchoring stud.
  • Another feature of the invention resides in the displaceable breech block which provides a safety. This is indicated schematically in FIGS. 4-11 by the spring 13, which when the breech block 10 is pushed down against the tension of the spring to the position for tiring, the front end of the housing bears against the part into which the stud is to be driven before the tool can be red.
  • the grip 1 bears the breech block 10 which is also displaceable along the guide tube 2 as in the previously described constructions, and its movement along the guide tube controlled.
  • a toothed-detent 15 is arranged in the breech block 10 and is pressed inwardly by a spring 17.
  • a pin 16 is positioned between the toothed detent 15 and the recoil mechanism 6 and is pressed toward the latter by the spring 17.
  • An extension 18 of the grip projects through the slot 9 into housing 2.
  • the tension spring 19 the recoil mechanism 6 is held against theextension 18 of the grip.
  • the cartridge chamber 3 is located in the recoil mechanism 6. After the introduction of a stud 20 into the muzzle of the barrel, the point of the stud 20 is placed against the ma- 4 1 terial to be bombarded.
  • the other lever arm has an elevation 25.
  • the elevation 25 strikes against the edge 26 of the housing and presses the lever 24 down, whereby the oppo- 1 site lever arm is raised and in this manner assists the 1 automatic ejection of the empty cartridge shell.
