Definitions

  • This invention relates to an automatic firearm wherein the closure member which has run back upon firing is again thrown forward bythe hammer spring by means of the hammer.
  • the spring which forms the hammer spring anfd closure spring exerts adriving effect uponthe closure member only during .a portion of the forward-running movement of the same, and indeed only until the hammer is held in its cocked position by the trigger.
  • the closure member in order to give the hammer room for its subsequent ignit-ing movement, continues its way alone, forwardly into the firing'position, with the barrel, as a result of the momentum previouslyimparted'thereto or. already connected with the previously retained barrel in a rearward tcnsioncd position, is further car- Q ried -aloug by its advancing means.
  • the closure element during its whole forward movement in the firearm is subjected to the forward driving action of the hammer spring andthe remaining-behind of the-hammer necessary for the igniting movement isfattained, or in other words the forward movement of the latter with respect to the hammer is produced, by elemen-ts arranged between these two parts, which during the closing movements are forced apart wedgewise, by positive guiding, between supporting surfaces of the closure element and the. hammer.
  • tensioning elements may be so formed and arranged that they themselves hold the forward running closure element and the hammer pressed apart in their mutual strainedposition until the firing and then either automatically, in dependence upon the running-in of the closure element into its forward end position, in the firearm. or, as, ⁇ by means of elements connected With the drawing device. are disengaged only by mean-1 or" the trigger deviccft'or 'freeing the irminer. lt would also. however. be possii nie from the tension elements proper, .fw prwvulr special, locking elements which will function of holding r'hc closure :mal the hammer in the tensed position given these two elements by the tension elements.
  • the tension elements are movably located either on the closure element or on the hammer. Then the tensing takes place by turning the tension element carrier about the longitudinal axis relatively to the other part by means of a suitable cam guide in the closure housing.
  • the device in accordance with the invention is suitable for all automatic firearms having a longitudinally movable closure element, regardless of the arrangement of the barrel (stationary or sliding barrel), the nature of closure (latched or unlatched closure) and the firing device (direct forward running firing through the forward-snapping closure element, or indirect firing by a latching element of the trigger device, which still maintains the hammer under tension with a locked closure).
  • the closure element is thereby disengaged positively from the hammer, in dependence upon the position of the hammer, and is brought forward with certainly into its forward end position in the firearm.
  • the spring which drives forward the hammer as well as the closure element, may, with a sliding barrel, also carry along the same back from its backward position, so that the special barrel-return device, heretofore necessary for this purpose, is eliminated.
  • FIG. 1 shows an exemplary embodiment of the invention in the form of an automatic firearm with a sliding barrel, latchable closure, and forward run firing, in longitudinal section, in various positions of operation.
  • Fig. 1 shows the utensioned firearm with forwardly moved parts and latched closure, immediately after firing a shot.
  • Fig. 2 shows the same after the shot, with the barrel moved back and the closure element thereby unlatched during said running back thereof, i
  • Fig. 3 shows the succeeding forward movement of the closure element at the instant of tensioning the hammer
  • Fig. et shows it shortly before firing the .succeeding shot.
  • the cylindrical housing c of the firearm are shiftablyv arranged the barrel b and the closure shell 0 connected therewith.
  • the closure element d which is so guided as to be longitudinally shiftable but not rotatable and is provided with locking threads d1, and which is latch able with the closure shell by means of a counter-threaded member e1 screwed upon the rear end thereof, with the locking threads d1 of the ring e which carries the closure elements.
  • the ring e is turned in known manner vby means of a lug e2 engaging in cam guides al of the housing upon the moving of the c losure shell c, for the unlocking or the subsequent locking of the closure, in known manner.
  • the closure element d is shiftablysupported the hammer f, upon the thickened rear end f1 of which presses a preliminarily tensioned spring g whose other end bears against the rear end surface of the housing a ofthe firearm.
  • the same spring g constitutes at one and the same time the hammer spring, closure spring, and the forwardmoving spring for the barrel.
  • a double armed tension lever or trigger h In the' head f1 of the hammer, is swingably supported a double armed tension lever or trigger h, one arm k1 of which, acted upon by the first turn of the spring g, cooperates with the rear end surface of the closure element d and the second arm h2 of which cooperates with an elongated lug a2 of the housing a of the firearm, which projects into its path, in a manner which will be explained. in greater detail hereinafter. 1
  • the arm h2 of the tension lever L strikes against the rear edge of the strip a2 and is thereby transiently retained, while the hammer f and thereby also the closure element d continue their travel forwardly.
  • the second arm hl of the tension lever L is swung forwardly against the end surface d2 of the closure element d which is somewhat inclined forwardly, and thereby acting like a knee lever, gives to the closure element d a forward motion with re spect to the hammer f, and to an extent necessary for the subsequent firing movement of the hammer f.
  • the tension lever h remains in this tension position, thus given thereto, during the further forward movement of the closure element which first produces a locking of the closure element d with the closure shell c, heretofore retained in known way in its rearward position, whereupon the closure ele ment d, the closure shell c and the barrelproceed ahead in locked-together position, into their forward end positions in the housing a of the firearm.
  • the hammer f is thereby tensioned.
  • the arm h2 of the tensioning lever h slides past the forward edge of the elongated lug or strip a2 and the hammer f, under the pressure of the spring g which presses the tension lever arm l1,1 sidewise, springs into the closure element d which meanwhile has come to rest, in order to fire forwardly the cartridge which has been introduced into the cartridge holder4
  • the tension lever h and the controlling lug a2 of the housing By suitable construction of the tension lever h and the controlling lug a2 of the housing,
  • Automatic firearm comprising a hammer, a closure element, a trigger element and a single spring which drives the closure element into its closing position and simultaneously drives the hammer forward into tiring position, the trigger being located between the hammer and the closure element, said hammer and closure element each having bearing surfaces between which the trigger exerts a wedge action to drive them apart a distance equal to the necessary travel of the hammer for firing.
  • Firearm in accordance with claim 1 comprising guide means whereby the trigger is brought into a position in the housing for producing the tensing of the hammer, only upon the return movement of the hammer and the closure element.
