Definitions

  • the invention relates to a safety device for firearms .having a longitudinally movable closure Velement which is particularly suitable for automatic hand weapons (guns and pis tots).
  • a multiple safety effect is secured with simple expedients, reliably preventing an unintentional firing and even procedures in connection with the weapon, which would lead to such firing or might produc-e any other disturbing eect.
  • the device in accordance with the invention in particular is so constructed that the safety element in its safety position, by engaging in a notch of the closure element guide (the housing of the weapon) will prevent an opening movement of the closure element, which is in the firing position7 and that also, by entering into the notch of the hammer, either cocked or not, will make the same itself immovable withrespect to the closure element.
  • the weapon which is cocked and ready for firing may be made safe', just as this is possible, on the other hand, with unloaded and uncocked weapons, in order to prevent an unintentional cooking and loading.
  • the hammer and the closure are simultaneously freed from an unintentional operation.
  • t is further advantageous, particularly in automatic firearms, to arrange the safety element, having a handle part for setting the same, in such manner in the closure element that in its safety position it is completely retracted into a cavity of said closure element, without having any parts projecting beyond the outer surface thereof.
  • This feature which is moreover applicable to all safety devices having a safety element located in the closure element, affords the possibility of constructing the rear portion of the housing of the weapon, serving as a closure guide after the firing of the shot, in a closed form and fitted to the contours of the usually rollshaped closure element, which facilitates the manufacture as well as the subsequent operation of the gun and decreases misfires upon using the firearm 5so,393, ana in- Germany september 11,1931.
  • Figure l is a side elevation of the Weapon partly in section with a closed closure vand uncocked hammer, not in the safety position
  • Fig. 2 is a cross section on the line A-B of Fig'. l, in th-e direction shown bythe ar ⁇ row, likewise with the same not inthe safety position
  • Fig. 4 shows the closed closure with a cocked hammer, inside view, in section, in safety position, and
  • Fig. 5 is a side elevation of the closed closure not in safety position.
  • the closure element b guided so as to be longitudinally shiftable in the housinga of the firearm, is latchable in known manner to the barrel 0 which slides to and fro on firing, by means of a shell l rotatably mounted on said barrel.
  • the hammer e is'v shiftably mounted in the closure element I) and the closing spring for the closure elementas well as the return braking and forward-feeding spring for the barrel, namely the'hammer spring act simultaneously upon said hammer e to tend to drive the same forward.
  • a double-armed lever g swingably mounted at the rear end of the hammer e, when the weapon is cocked will lie, as shown in' Fig.
  • the dsc-shaped'safety element i is pivotally mounted about the stud b2, in a slot b, of the closure element b, and in coopera'- tion' with the actuating device l for shifting the same produces a safety setting of the closure element b, out of itsv firing position, in cooperation with the shoulder va1 of the housing c of the firearmv and simultaneously by the entering of a casing portion 2 into the slots el, e2 ofthe hammer e, loc-ksv the ⁇ same against movement with respect to they closure element.
  • the slots el, e2 instead of consisting of notches in the body of the hammer, as illustrated, could also be formed of the rear or forward end surface of an upper strip of the hammer, which could also at the same time serve for guiding the latter straightly.
  • theslot ell and/or e2 of the hammer which is located either uncooked (Fig. l) in its forward end position or cocked (Fig. 4) in a-Y somewhat drawn back position, 'will' lie opposite a sickle-shaped notch 3 of the safety element ,and the hammer can then either be returned to the cocked position or can springforward from this position in order to irethe cartridge.
  • the safety flap l has swung to such extent into the suitably deep and wide cavity b1 of the clesure element so that it has become retracted completely within the outer confines of the closure element (Fig. 2').
  • the closure element can, therefore, without being obstructed by projecting parts of the safety device, run back in the rear portion of the housing a vof the firearm, which suitably encloses the same.
  • a safety ,setting o f the firearm with the closure closed is possible as well in the uncooked asin thecoclred position of the hammer. 'In both cases thereby the safety flap il, folded over into'th'e lposition shown in Fig. 3, will become positioned in front of the rear limit alof the cavity a2 of the housing a of the weapon, which serves for introducing cartridges into the magazine as well as' for ejecting the red cartridge shells. Thereby the yclosure element Sis secured against opening. Simultaneously the safety element has engaged in the slot el or ⁇ e2 of the hammer e, yand locks the latter with'res pect to the closure element b.
  • the hammer spring f is used in a particularly effective manner.
  • a central projection i will be ,causedV to lie against its rear end ysurface in the safety notches @land/or e2 yof the hammer, and vwill thereby force the s ame back somewhat in opposition to the forward drivingaction of the hammer spring f.
  • Yin turning the safety element out'of one or other of yits working positions retains the same stationary in both positions mentionedand an Aunintentional shifting of I they safetydeyicey is prevented.
  • Safety .device forfirearms having a. longitudfriolly movable Closure.. .elementi particularly for automatic hand firearms, comprising a closure element, a guide for said element, a hammer, a safety element mounted in the said closure element which pre- Y vents va movement of the said hammer either cocked or uncooked, with respectv to the closure element, when said safety element is in its ASafety position, by engaging 'in in ,Said hammer, ausl also provento oel-oponing movement of the closure element vwhen it is in the firing position, by engaging behind a shoulder of the closure elementl gillda;
