  • Patent number: 10578387
    Abstract: A trigger mechanism for a repeating rifle includes a sear pivotable about a first axis, a detent lever pivotable about a second axis and having an extension with a catch that is engaged with the sear when the mechanism is cocked, and a trigger pivotable about a trigger axis, wherein upon rotational actuation thereof, the trigger acts directly upon the detent lever, without any intervening components, pivoting the detent lever about the second axis in a direction opposite to the trigger rotation, and releasing the sear projection from the detent lever catch. In embodiments, the trigger pull is adjusted by an adjusting spring driven by an adjusting screw that is freely accessible from beneath the trigger mechanism. Embodiments further include a sear return spring between the sear and detent lever, and/or a trigger return spring opposing the adjusting spring that holds the trigger in a defined position without play.
