Definitions

  • the present invention relates to fire arms, including detonators therefor, for firing a charge.
  • an object of the present invention to provide a fire arm capable of firing charges, which fire arm is simple and adapted to be mass-produced easily at low cost, and which is very reliable in that it is so made that there is no danger of it going off accidentally.
  • a detonator for use with a fire arm, which detonator comprises, basically, a housing, a mounting element arranged in the housing and adapted to support at one end a percussion cap, a firing pin arranged in the mounting element and movable therein between a cocked position spaced from a percussion cap held by the mounting element and a released position wherein the firing pin strikes the percussion cap, this firing pin having near one end thereof a reduced portion and an end portion having a cross section larger than that of the reduced portion, spring means continually urging the firing pin out of the cocked position, a slidably mounted retaining member cooperating with the above-mentioned one end of the firing pin for retaining the latter in its cocked position, this retaining member having an opening composed of a first portion of a size sufficient to allow the end portion of the firing pin to pass therethrough and a second portion of suificient size to accommodate the reduced portion of the firing pin but of ins
  • the present invention further resides in a fire arm which incorporates a detonator as described above, as well as a firing t-ube attached to the mounting element, the firing tube being adapted to contain a charge or cartridge to be detonated by the detonator mechanism.
  • FIGURE 1 is a sectional view of a detonator according to the present invention.
  • FIGURE 2 is a plan view of the detonator shown in FIGURE 1.
  • FIGURE 3 is a perspective view showing a modified embodiment of a detonator according to the present invention.
  • FIGURE 4 is a sectional view of a fire arm according to the present invention, the same including a detonator of the type shown in FIGURE 3.
  • FIGURE 5 is a sectional view of another embodiment of a fire arm according to the present invention, the same also including a detonator of the type shown in FIG- URE 3.
  • a detonator comprising a cup-shaped housing 1 made, for example, of drawn sheet metal and formed with inwardly extending corrugations or beads 2 which fix the positions of two transverse support plates 3.
  • the latter support a mounting tube 4 carrying a firing pin 5 encompassed by a firing pin spring 6, as well as a carrier 7 which carries a primer or percussion cap 8.
  • One end of the firing pin 5 is provided with an annular groove 9 and, in the cocked position of the firing pin, is detachably connected with a slide member 11 having a handle 11a.
  • the member 11 is slidably arranged between one end face of the mounting tube 4 and an end plate 10, and is provided with a generally keyhole-shaped opening 13 having a narrowed portion 12, it being within this narrowed portion 12 that a reduced neck portion 9a formed by the groove 9 is located, thus holding the firing pin 5 in its cocked position. If the slide member 11 is then moved leftwardly, as viewed in FIGURE 1, the spring 6 will cause the firing pin to move downwardly, this movement being made possible as soon as the enlarged portion of the opening 13 comes into alignment with the full-sized upper end portion 9b of the firing pin 5. The firing pin 5 will then strike the percussion cap 8, thereby detonating the charge.
  • the safety mechanism for preventing the inadvertent release of the firing pin comprises a leaf spring 14 which is rotatably mounted on the end plate It ⁇ by means of a rivet 15.
  • the spring 14 has a downwardly depending end portion 16 which extends through an opening 17 of the slide member 11 and thus prevents the latter from being displaced.
  • the leaf spring 14 is provided with a handle constituted by a wire ring 18 which passes through a tongue 19 integral with and bent out of the plane of the leaf spring 14 and which ring is detacha-bly connected to an overlying end 20 of the leaf spring.
  • the latter has a portion 21 which is bent out of the plane of the ring 18 and is looped, as is best seen in FIGURE 1.
  • the end plate 10 is formed with inwardly extending elongated ridges 22 which form guides between which the member 11 may slide. Also, the end plate 10 is pressed outwardly in the region of the firing pin 5 and the rivet 15.
  • the lower end of the mounting tube 4 extends out of the housing 1 and is provided with an external thread 23 which may receive a cartridge.
  • This cartridge is not shown in FIGURES l and 2; instead, the threaded end of the mounting tube 4 carries a seal 24 as well as a parafiin-lined protective cap 25.
  • the mounting tube 4 may be applied to the housing 1 which is then threaded directly to the cartridge or the like.
  • a bayonet-type coupling may be provided.
  • all openings of the housing 1 will be sealed by an appropriate substance, as, for example, paraflin, so as to make the housing fluid-tight during transport of the detonator.
  • FIGURE 3 is a perspective view of a modified embodiment of a detonator in which the safety mechanism for preventing inadvertent release of the firing pin 5 comprises a sector-shaped member 27 having two handles 26, which member is pivotably mounted at the center of the end plate It).
  • This member 27 is provided with two spaced-apart abutments 28 arranged on opposite sides of the slide member 11 which, as explained above,
  • the safety mechanism further includes a spring-biased pin or lug 29 for preventing the inadvertent disengagement of the abutments 28.
  • This pin or lug 2.9 has to be depressed before making it possible for the member 27 to be pivoted, in the direction of the arrow 51, into a position in which it will free the slide member 11.
  • Either of the above-described detonators may be massproduced at low cost, experience having shown that this is possible at approximately half the cost of heretofore known detonators.
  • a device according to the present invention is very reliable in that as long as the safety mechanism is engaged, there is no danger of inadvertently releasing the firing pin. Consequently, the detonator may be safely carried in a pocket of ordinary clothing, it being unnecessary to provide special safety containers.
  • the safety mechanism is very reliable, it can be moved rapidly to a position in which the detonator is ready to be actuated.
  • the detonator can be made very small; in practice, it may have a diameter as small as 37 millimeters and a height as low as 32 millimeters. Also, the structure is such that it is operative irrespective of its attitude.
  • FIGURE 4 shows a detonator incorporating the safety mechanism of FIGURE 3 in combination with a barrel or firing tube 30 constituted, for example, by a drawn, seamless steel tube.
  • the side of the tube 30 which faces the detonator housing 1 is closed by a ring 31 suitably attached to the tube 30, as, for example, by inwardly directed beads 2'.
  • the ring 31 has an internal thread 32 which joins a propellant tube 33 adapted to receive the propellant charge 34.
  • the propellant tube 33 has an internal thread 35 which is screwed onto the external thread of the mounting tube 4.
  • a detonator charge 37 which is surrounded by a sheet metal sheath 37a and which is formed with an axial passage 36 lined by a stepped tube 37b.
  • the latter has arranged within it a delay composition or pellet 38 and a detonator capsule 39, the free upper end of the tube 37a being closed off by a screw 40 having a knurled head portion. Sealing discs 41 and 42 are provided for preventing the entry of moisture, thereby insuring the operability of the detonator charge. An additional sealing disc 43 is arranged between the ring 31 and the detonator housing 1.
  • the firing tube 30 is encased within a hand-protective knurled or otherwise profiled sheath 44 made of rubber or other suitable material, the ends of this sheath abutting the sealing disc 43 and a beaded over or flanged end 45 of the tube 30.
  • the sheath may be held in place by gluing or pressing it onto the tube 30, or by spraying a suitable substance right onto the tube.
  • the combination shown in FIGURE 5 differs from that shown in FIGURE 4 in that the firing tube contains a flare or tracer composition 46' instead of a detonator charge.
  • the tube 30 contains a cup-shaped container 47 which has been pushed into the tube and which contains a propellant charge 34 capable of being detonated by the percussion cap 8, the bottom of the container 47 being perforated at 47a.
  • the free end of the firing tube 30 is closed off by pressed-in sealing discs 41 and 42, as well as by a plastic cap 50 which is pressed into the mouth of the tube.
  • the sheath 44 and/or the detonator housing 1 may be colorcoded to indicate the color of the composition 46, as, for example, by means of a stripe of the appropriate color. This stripe may be applied with luminous paint; if the composition 46 is a two-color flare, one of the two colors may be applied to the sheath 44 and the other to the detonator housing 1.
  • the charge By virtue of the above-described sheath 44, it is easy to aim the charge in the flash tube; if the charge is an explosive one and the item is used as a weapon, the charge can be fired from cover without it being necessary for the user to expose himself, since all he has to do is to release the safety mechanism and to push the slide member 11. Furthermore, the accuracy with which the charge may be aimed is substantially greater than that with which a conventional hand grenade can be thrown.
  • the charge may be caused to explode when it strikes its target, thereby making it impossible for the missile to be thrown back, as may be the case with conventional hand grenades which are thrown prematurely. It will be noted that no impact percussion cap is required, thereby further reducing the costs of the item.
  • detonator and firing tube are completely waterproof, and are fully operative at temperatures of between '43 C. and +50 C.
  • a detonator mechanism comprising, in combination: a generally rigid and cup-shaped housing; two spaced transverse support members arranged 'Within said housing; a tubular mounting element arranged in said housing and supported by said support members; a percussion cap arranged at one end of said mounting element; a firing pin arranged in said mounting element and movable therein between a cocked position spaced from said percussion cap and a released position wherein said firing pin strikes said percussion cap, said firing pin having near one end thereof a reduced portion and an end portion of a cross section larger than said reduced portion; spring means continually urging said firing pin out of its cocked position; a slidably mounted retaining member cooperating with said one end of said firing pin for retaining the latter in its cocked position, said retaining member having a generally key-hole-shaped opening composed of an enlarged portion of a.
  • said slide member having a portion extending exteriorly of said housing and being movable relative thereto between a retaining position wherein said reduced portion of said firing pin is received within said narrowed portion of said opening, thereby retaining said firing pin in its cocked position, and a firing position wherein said enlarged portion of said opening is in alignment with said end portion of said firing pin, thereby permitting the latter to move to its released position under the influence of said spring means; and a safety device cooperating with said slide member for preventing unintentional movement thereof from its retaining position to its firing position.
  • said safety device comprises a pivotable sectorshaped member provided with two spaced-apart abutments arranged on opposite sides of said slide member, said sector-shaped member being pivotable between a locking position in which one of said abutments engages the underside of a widened handle portion of said slide member, thereby preventing movement of said handle portion out of its retaining position, and an unlocked position in which said handle portion of said slide member is free to pass between said spaced-apart abutments.
  • a fire arm comprising, in combination: a generally rigid and cup-shaped housing; two spaced transverse support members arranged within said housing; a tubular mounting element arranged in said housing and supported by said support members; a percussion cap arranged at one end of said mounting element; a firing pin arranged in said mounting element and movable therein between a cocked position spaced from said percussion cap and a released position wherein said firing pin strikes said percussion cap, said firing pin having near one end thereof a reduced portion and an end portion of a cross section larger than said reduced portion; spring means continually urging said firing pin out of its cocked position; a slidably mounted retaining member cooperating with said one end of said firing pin for retaining the latter in its cocked position, said retaining member having a generally key-hole-shaped opening composed of an enlarged portion of a size sufficient to allow said end portion of said firing pin to pass therethrough and a narrowed portion of sufficient width to accommodate said reduced portion of said firing pin but of insufi
  • said firing tube further contains a ring secured to one end of said firing tube; a propellant tube containing said propellant charge and connected to said ring, said propellant tube being threaded onto said mounting element; a sheath containing said further charge, the latter having an axial bore lined with a stepped tube and said delay capsule being arranged within said stepped tube; a detonator charge also arranged within said stepped tube; a screw closing off the open end of said stepped tube; and sealing discs closing off the other end of said firing tube.
