Definitions

  • the invention relates to a trigger device for the multipart breech mechanism of an automatic firearm, the device having a striker which is alternately cocked and released by the breech mechanism as the latter moves forward and backward.
  • a striker which is alternately cocked and released by the breech mechanism as the latter moves forward and backward.
  • operating faults occasionally occur during continuous firing due to the fact that, after the breech mechanism has moved forward, the recoil energy of the rear part of the breech mechanism is not always sufiiciently absorbed by the arresting device, for example an arresting lever.
  • An object of the invention is to eliminate the drawbacks indicated above by means which are as simple as possible.
  • a control lever operatively connected both to the striker or hammer and to the breech mechanism, the said control lever intercepting the released striker by locking and control means and releasing it for firing movement only when the breech mechanism is in its final, forward, closing position.
  • control lever is preferably mounted on a pivot which, in turn, is arranged on a plate mounted on the pivot pins of the striker and of the trigger. In this way it ispossible to replace a defective device in its entirety and subsequent attention to the trigger box or on parts of the breech mechanism which can only be carried out with difficulty is avoided.
  • reference 1 designates a trigger box ,or casing in which all the parts of the trigger and safety arrangement are housed in the usual manner.
  • the trigger device consists essentially of the trigger 2, a striker or hammer 3, a pressure fork 4 which compression spring 5, a control lever 6 and a release lever 7.
  • Reference character 8 designates the rear part of a two-part breech mechanism; The drawing shows the trigger device in the continuous fire position. The part 8 of the breech mechanism is in its forward closing position. During its forward movement, the part 8 has actuated the release lever 7 and released the hammer. The striker can now move forward, actuated by the pressure fork 4, under the force of the compression spring '5 and fire the cartridge.
  • the control lever 6 which is pivotally mounted in the rear zone of the trigger box on a pivot pin 9, serves to control the movements just described.
  • the hammer 3 and the control lever 6 are operatively connected by way of a control cam or pin 10 arranged on the hammer and a control slot 1 1 provided in the control lever and in which the cam 10 slides.
  • the control lever has, at its free front end, a projection 12 having a locking edge or surface 13 and an inclined surface 14.
  • the control lever 6 operates in the following manner.
  • the part 8 of the breech mechanism moves forward, its surface 19 slides over and beyond the locking edge '13 of the control lever 6 and during this movement it holds the control lever in its lower position, as is shown in the drawing.
  • the hammer released by the breech mechnism by means of the release lever 7, has moved from a position in which cam 10 is locatedat a to a position in which the cam is at b during this time.
  • the part 8 of the breech mechanism now releases the control lever 6, so that the latter can be lifted by the control cam 10 of the striker moving along the control slot 11, this being necessary to allow the striker to perform its movement.
  • the extent of the recoil can be controlled, so that it is possible to control the rate of fire of the weapon as a result of the different time effects, that is the time before the rear part of the breech mechanism is finally stopped.
  • a very simple method is provided of obtaining a reduction of the rate of fire which may possibly be desired.
  • the invention can also be employed in simple manner in already existing weapons without replacing the trigger box or diflicult dismantling by mounting the pivot 9 on a plate 16 which in turn is mounted on the pins 17 and 18 of the hammer and the trigger.
  • control lever 6 may also be designed so that it also has the function of a release lever.
  • release lever 7 can be dispensed with.
  • a trigger device for multi-part breech mechanism of automatic firearms comprising a hammer pivotally mounted and which is alternately cocked and released by the breech mechanism moving forward and backward, a control lever having locking and control surfaces and having a slot therein, and a control cam mounted on the hammer and projecting in the slot, said control lever intercepting the release hammer by means of the locking and control surfaces to release the hammer for firing 4 purposes only when the breech mechanism is in its final forward closed position.
  • a trigger device in which a recess is provided in the breech mechanism to cooperate with the locking means of the control lever for the purpose of cocking the hammer.
  • a trigger device in which the control surface of the control lever is in the form of an inclined surface provided at the free end thereof having an angle so that, while avoiding any recoil, immediate locking of the breech mechanism occurs when the latter reaches its forward closing position.
  • a trigger device in which the control lever is mounted on a pivot which is arranged on a plate mounted on the pivot pins of the hammer and of the trigger.
