Abstract
A functioning mechanism for a small caliber automatic weapon includes a translatable and rotatable sear, and a rotatable hammer. The sear includes a hooking element adapted to contact a bearing surface of the hammer to render the hammer immobile. Rotating movement of the sear is controlled by the hammer in such a way as to obtain clean contact between the hooking element and the bearing surface.
Claims17
A functioning mechanism for an automatic weapon comprising:
- a rotatable trigger;
- a sear that moves between a starting position and a firing control position as said rotatable trigger is actuated, said sear including a hooking element;
- and
- a hammer rotatable between a cocked position and a firing position during firing of said weapon, said hammer including a bearing surface that is adapted to electively contact the hooking element of the sear,
- wherein the sear exerts a rearward axial force to cause the hammer to rotate towards a cocked position when the sear moves to the firing control position, and wherein the sear rotates from a low position to a high position after the hammer reaches the cocked position.

A mechanism for an automatic weapon, comprising:
- a trigger;
- a sear that moves between a starting position and a firing control position as said trigger is actuated;
- a hammer, coupleable with said sear, said hammer being rotatable between a cocked position and a firing position during firing of said weapon;
- and
- means for positively locking said sear to said hammer as the hammer moves from an intermediate position toward the cocked position, wherein said means for positively locking includes means for translating the sear to the firing control position to cause the hammer to rotate toward the cocked position, and for rotating the sear from a low position to a high position after the hammer reaches the cocked position.

A functioning mechanism for an automatic weapon comprising:
- a trigger;
- a sear that moves between a starting position and a firing control position as said trigger is actuated, said sear including a hooking element;
- a hammer rotatable between a cocked position and a firing position during firing of said weapon, said hammer including a bearing surface that is adapted to selectively contact the hooking element of the sear;
- means for allowing the sear to exert a rearward axial force on the hammer to cause the hammer to rotate towards a cocked position when the sear moves to the firing control position;
- and
- means for rotating the sear from a low position to a high position after the hammer reaches the cocked position.
