Definitions

  • the invention relates to an apparatus for sealing fasteners, comprising a barrel holder, a cylinder head secured to the barrel holder, a barrel mounted to slide in the breech, a counterweight mounted to slide in the barrel, and a tip guide, the rear end of the tip guide being in contact with the front end of the barrel.
  • the present invention aims to improve such weights sealing devices by providing a simple power variation device, easy to perform and allowing a range of large power variations with large degrees of freedom for the structure of the device.
  • the present invention relates to a sealing device of the type mentioned above, characterized in that it comprises a power adjustment ring mounted screwed on the tip guide and on the barrel holder, the ring and the front part of the barrel being arranged to cooperate together so that the rotation in one direction of the ring causes the barrel to slide towards the front of the device, while the rotation of the ring in the other direction causes a sliding from the barrel to the rear under the action of the tip guide, the sliding of the barrel regulating the volume of the gas expansion chamber behind the counterweight.
  • the barrel is fixed in rotation and has a groove in which a finger can protrude from a return pawl of the counterweight.
  • the power adjustment of the device of the invention is advantageously combined with a reminder of the counterweight in the firing position.
  • the apparatus of the invention referenced as 2 in the drawing, comprises a counterweight 4 which can be driven in displacement under the action of the combustion gases produced by a cartridge 6 in order to drive a fixing element, not shown, in a material intended to receive it.
  • the device 2 comprises a housing 8 in which is disposed a gun holder 10 screwed onto a cylinder head 12 in the form of a ring. Inside the barrel holder 10 is disposed a barrel 14 in the bore 16 of which the counterweight 4 is slidably mounted. The barrel 14 is slidably mounted in a bore 18 formed in the cylinder head 12.
  • the barrel 14 has a longitudinal groove 20 in which a finger 22 can protrude from a counterweight return pawl 24 pivotally mounted.
  • the end of the groove 20 disposed near the tip guide of the device which will be discussed below, is chamfered so as to have a cam surface, or ramp, 26 arranged to cooperate with the finger 22 and thus remove it from the groove when the device is supported.
  • the barrel 14 has at its end close to the tip guide a flange 28 extending radially outward and cooperating with a flange 30 extending radially inward formed on a power adjustment ring 32.
  • the ring 32 is screwed inside the end of the barrel holder 10, close to the tip guide, and comprises an enlarged portion 34 forming a shoulder 36 cooperating with a surface 38 formed at the end, close to the tip guide, of the barrel holder 10, when the ring 32 is fully screwed into the barrel holder 10.
  • a tip guide 40 is screwed into the ring 32 and comprises a ring 42 screwed firmly against the end 44 of the ring 32 facing towards outside the appliance.
  • a lock 50 is pivotally mounted under the action of a spring on the end, close to the tip guide, of the housing 8 and comprises a finger 52 extending inside a locking notch 54 formed at least at the end, close to the tip guide, of the gun holder.
  • the counterweight return pawl 24 is pivotally mounted against the action of a spring at the end, directed towards the tip guide, of a rod 56 which extends through a bore 58 formed in the barrel holder 10, a bore 60 formed in the cylinder head 12, and a bore 62 formed in the housing 8, the rod 56 having a threaded end 64 extending through a bore 66 formed in a operating cover 68 covering the rear end of the housing 8.
  • a bolt 70 is screwed onto the threaded end 64 of the rod 56 to hold this rod 56 in place.
  • the device 2 can be disassembled, for example to be cleaned, by actuating the latch 50 and removing the bolt 70.
  • a chamber support plate 72 is mounted in the housing 8 and has a boss 74 extending forward, in which a combustion chamber 76 is formed.
  • the chamber plate 72 is provided with a bore 88 opening out at the rear end so that the boss of the chamber of the counterweight 4.
  • the bore 88 is dimensioned so that the bossing of the combustion chamber 74 can be introduced into bore 88 while the device is resting when the device is ready to fire, as shown in FIG. 2.
  • the apparatus 2 is shown in the ready-to-fire position, position in which the power level of the apparatus is at its maximum and in which the rear face 5 of the counterweight 4 is in its position closest to the front end surface 75 of the boss of the combustion chamber 74.
  • the gas expansion chamber 90 occupies a minimum volume in which the combustion gases produced by the cartridge can relax before that the counterweight is entrained in the bore 16 of the barrel.
  • the dimensions of the expansion chamber 90 are determined by the cooperation of the rear face 5 of the counterweight 4 with the front face 15 of an inwardly extending collar provided at the rear end of the barrel 14.
  • the counterweight 4 After firing the device, the counterweight 4 is driven in the bore 16 of the barrel, the rod 92 of the counterweight 4 passing through the bore 41 of the tip guide 40. It will be readily understood that the fixing element , not shown, intended to be driven by the counterweight, is disposed in the bore 41 of the tip guide prior to firing the device.
  • the device After firing, the device is released from the bearing face of the material intended to receive the fixing element and the spring 78 recalls the interior sub-assembly in the position shown in FIG. 1, the only difference being in the fact that the counterweight 4 is in a driven position inside the bore 16 of the barrel with its head 94 disposed behind the finger 22 of the pawl 24, so that the latter, having pivoted to protrude at the interior of the bore 16 of the barrel is in a position where it can cooperate with the front surface 95 of the counterweight head 94.
  • the flyweight 4 is returned to the firing position by grasping the operating cover 68 with one hand, the other hand grasping the handle 108 of the device and pulling the operating cover 68 backwards.
  • the rod 56 is thus pulled backwards with the pawl 24.
  • the cooperation of the finger 22 of the pawl with the surface 95 of the counterweight head causes the counterweight 4 from its position after firing to its position before firing.
  • the rear face 5 of the counterweight 4 comes into contact with the face 15 of the inner collar of the barrel, the rearward movement of the operating cover 68 takes place against the action of the spring 78, the counterweight 4 then having been returned to the firing position.
  • the cover 68 of the rod 56 and the pawl 24 are then pushed forward and returned to their respective position shown in Figure 1.
  • the barrel holder 10 is locked in the front position by a ball 100 housed in a hole 101 formed in the cylinder head 12, and having a diameter greater than the thickness of the wall of the cylinder head 12.
  • the power level of the apparatus 2 can thus be adjusted from a high kinetic energy level, in which a maximum counterweight kinetic energy is developed by the cartridge, up to an average energy level in which the kinetic energy of the intermediate level flyweight is developed, while only slightly moving the adjusting ring 32 over a distance of a few centimeters, without consequently varying the overall length of the apparatus.
  • vents 96 (FIG. 3) which extend into the wall of the breech part 12 in which the barrel is slidably mounted and which open into a cavity 98 which is preferably isolated from the atmosphere and which is arranged between the barrel 14 and the barrel holder 10.
  • the vents 96 the power of the device can be adjusted to a low level without having to excessively unscrew the adjustment ring, or to excessively lengthen the whole device.
  • the device 2 can easily be dismantled by unscrewing and removing the bolt 70.
  • the lock 50 is then actuated to pivot in a counter-clockwise direction, so as to release the finger 52 from the locking notch 54.
  • the entire sub-assembly, comprising the barrel holder 10, the cylinder head 12, the barrel 14, the adjustment ring 32 and the tip guide 40, can then slide out of the housing 8.
  • the device is reassembled by reintroducing the sub-assembly into the housing 8, the latch 50 being held in the retracted non-locking position.
  • the bolt 50 is then released and the bolt 70 is screwed back onto the projecting end 64 of the rod 56.
