- TRIGGER MECHANISM FOR USE WITH AUTOMATIC FIREARMS Filed April 29, 1966 I 1 f O I 4 Mm N United States Patent 3,358,560 TRIGGER MECHANISM FOR USE WITH AUTGMATIC FIREARMS Leslie Ernest Rutiell, Dagenham, England, assignor to Sterling Engineering Company, Limited, Dagenham, England Filed Apr. 29, 1966, Ser. No. 546,221 Claims priority, application Great Britain, May 7, 1965, 19,333/65 4 Claims. (Cl.
- firing may be controlled by a pivoted sear movable by the operation of a trigger.
- the sear can also be capable of longitudinal movement, by means of a pin and slot coupling, which enables the sear to be decoupled from the trigger, in a position in which firing is prevented, the sear arresting the bolt after recoil.
- the sear 5 is mounted for pivotal movement about a pivot rod 6 and a link 27 is rotatably coupled to the sear by being also pivotally mounted on the rod 6.
- the link 27 can also pivot about a fulcrum provided by a further pivot rod 28 on the frame 1 at a position displaced from the pivot rod 6. It will be evident that pivotal movement of the link 27 about the pivot rod 28 through a small angle causes the upper end of the link coupled to the sear 5 to perform an arcuate movement about the axis of rod 28.
- the sear itself is moved substantially longitudinally of the firearm when the trigger frame 1 is fitted thereto.
- the spring 8 Whilst the trigger 2 is still held, the spring 8 is under maximum compression and causes the sear 5 to rotate to a position in which it is still disconnected from the trigger but in which the part 20 lies in the path of the bolt as it flies forward after recoil.
- the bolt is therefore arrested in its cocked position.
- the bolt then exerts forward pressure on the sear 5 and the sear will move forwardly, by pivotation of the link 27 about the pivot rod 28, until the step 4 engages the step 3 on the trigger.
- the sear 5 As long as the trigger is held the sear 5 is prevented from moving to its most forward position, but when the trigger is released, movement of the sear to this most forward position will take place and the firearm will be in a condition to fire another round.
- the single link 27 can be replaced by a more complex link system, provided that at least substantially longitudinal movement of the sear 5 is permitted.
- the invention could be embodied in mechanisms in which the sear is not directly engaged by the trigger.
- the invention can be embodied in a variety of trigger mechanisms and the trigger mechanism shown in the drawings may be modified in a variety of ways within the scope of the invention as defined in the following claims.
