Abstract

See full text

A trigger mechanism has a hammer, a hammer spring, a disconnect rest and a sear. The sear translates along a longitudinal axis between a rest position and a break point and also moves in an arc around a rotational axis from the break point to a disconnect position. The sear has a hammer side that presses against and rotates the hammer's cam end of as the sear moves between the rest position and the break point and thereby rotates the hammer's striking end around the hammer's pivot point between its seated and cocked positions. The support side contacts the disconnect rest's face as the sear moves between the rest position and the break point. The support side has an edge that is located at the ledge at the break point position. The hammer spring forces the sear to the disconnect position as the edge moves past the ledge.
