Definitions

  • This invention relates to an apparatus, hereinafter termed a bolt gun, for shooting bolts and the like into a solid mass, for example brickwork, masonry, steel plates and the like.
  • a common kind of bolt gun has a casing part containing the barrel and a handle part comprising a barrel lock, a tiring mechanism for the striking pin and a handle, the barrel casing part and the handle part being connected together and being brought into a relatively bent or inclined position for loading and unloading the gun.
  • the object of the present invention is to provide an improved bolt gun of the kind referred to having a pivoted barrel casing part which does not possess the above-mentioned disadvantages, and is characterised above all by a simple construction of the connecting and locking means provided between the barrel casing part and the handle part.
  • the releasable connection between the handle part and the barrel part is in the form of a bayonetlike joint, guide pins provided on one part, preferably the barrel casing part, engaging in guide grooves formed in the other part in such a way that the two parts, when pushed together, can be locked by relative rotation about their longitudinal axis and, when drawn apart, can be brought into their relatively bent or inclined position.
  • the guide grooves are at the rearward end and on the inside of the handle casing part and are approximately Z-shaped.
  • the grooves may then consist of a longer and shorter axial groove which are offset relatively both laterally and in the longitudinal direction and a transverse connecting groove, the casing of the handle part being provided on each side of these guide grooves with a semicircular recess in order to enable the casing of the barrel part to be bent relative to the handle part.
  • the longer axial groove is provided with a lateral groove which leads to the outside.
  • the longitudinal extent of the shorter axial groove is such that, for the purpose of preventing premature tiring, it enables the barrel casing part together with the locking member to be pushed in by an additional distance which represents a safety path for the barrel.
  • the front end of the short axial groove preferably forms a recess for the pin of the barrel casing part in order to prevent unintentional rotation and consequent unlocking of the barrel casing part relative to the handle part.
  • Figure 1 is a side elevation, partly in section of the gun
  • Figure 2 is a plan showing details of the connection between the barrel casing part and the handle part, t0 a larger scale with the barrel part bent or inclined to the handle part, and
  • Figure 3 shows a development of guide grooves which are provided in the handle part.
  • the bolt gun consists essentially of a barrel casing part 2, which contains an axially movable barrel 1, and a handle part 3 which is releasably connected to the part 2 and includes a handle 4, a firing mechanism for the striking pin and a barrel locking member 5.
  • the barrel locking member 5 is mounted in a casing 6 of the handle part 3 so as to be axially displaceable therein and is acted upon by a helical compression spring 7.
  • a striking pin 8 is mounted in the locking member 5.
  • the s-triking pin 8 is actuated by a hammer 9 which is provided at its front end with a flange 10 against which a spring 11 bears. At its rear end the spring 11 is supported against a wall 12 provided in the handle part 3.
  • the hammer 9 is provided at its rear end with a projecting head 9 which co-operates with a lug 15 of a trigger 16.
  • the trigger 16 is acted upon by 1a compression spring 17 which is supported against the casing of the handle.
  • the releasable connection between the barrel casing part 2 and the handle part 3 consists of a kind of bayonet joint, the barrel casing 2 being provided with two diametrically opposite guide pins 18 which engage in guide grooves tat the front end of the handle part 3 on the inside of the casing 6. These guide grooves are also arranged diametrically opposite one another.
  • the casing 6 of the handle part is provided on each side with a semi-circular recess 19 in order to enable the barrel casing part 2 to be turned relative to the handle part 3.
  • the guide grooves are of approximately Z-shaped form, and consist of a longer groove 20 and a shorter groove 21 which are relatively displaced both laterally and longitudinally and are connected by a transverse groove 22.
  • the front end of the shorter axial groove 21 forms a recess 23 and a groove 24 leading into the recess 19 is branched off laterally from the longer axial groove 20.
  • the guide pins 18 are located at the front end of the longer axial groove 20 (position 32, Figure 3).
  • the cartridge, or the bolt and the cartridge can be inserted into the breech 36 of the barrel.
  • the barrel casing part 2 is turned until the axis of the barrel coincideswith the longitudinal taxis of the handle part-3.
  • the barrel casing part is pushed into the handle part 3 so that the pins 18 arrive in the position illustrated by the reference 30 in Figure 3.
  • the barrel is rotated in a clockwise sense through relative to the handle part as seen from the muzzle end of the gun.
  • the hammer' snaps forward under the action of its spring 11 and actuat'es theA firing pin and thereby fires the shot.
  • the unloading of the gun takes place in the opposite sequence when the pins 18 pass through positions 33 and 311 and nally arrive in the starting position 32 corresponding to the bent position of the barrel casing part 2.
  • the pins 18 starting from the position 32 are moved into a central position 35 in which the barrel part can be completely released from the handle part by rotation in an anti-clockwise sense, as seen from the muzzle end of the gun, whereby the pins 18 slide out of the transverse grooves 24 and arrive in the position 31.
  • the parts 2 and 3 are assembled again in a reverse manner.
  • the bayonet connection between the barrel casing part 2 and the handle part 3 has the particular advantage that if there is failure to detonate the cartridge, the releasing device for the striking pin on the one hand, that Vis to say the actual firing mechanism and the bolt and breech on the other hand are completely separated from one another so that accidents are avoided.
  • a device for propellingbolts and the like comprising in combination, a barrel casing, a hollow handle part releasably secured to said barrel casing, a barrel displaceable in said barrel casing, said handle part being displaceable on said barrel, a ring pin mechanism in said handle part, said handle part having a grooved end portion on its internal face, said grooved portion consisting of a pair of longer and shorter, spaced axial grooves, a transverse groove connecting said grooves, said end portion formed with arcuate recesses, bayonet means releasably connecting said handle part and said barrel casing, said means including a pair of diametrically opposed radially extending guide pins secured to said barrel casing and engaging in the grooves of said grooved portion, said pins being axially and rotatably displaceable in the latter, whereby both said barrel casing and barrel may be locked in axial alignment or inclined towards one another by relative axial and rotary movement of said handle part and said barrel casing.
  • said grooved portion is further provided with a lateral groove leading from the longer of said axial grooves to the exterior of said handle part, whereby said barrel casing may be detached from the former.
  • each of the shorter axial grooves is provided with a recess for receiving one of Said pins, to thereby prevent unintentional unbolting of theV latter from said handle part.
