ABSTRACT:

BACKGROUND OF THE INVENTION
Rifles using a pivotal and reciprocal bolt have been previously used for rim fire rifles. The bolt is pivoted by its rearward end within the receiver and is normally locked against longitudinal movement by a cross lug that pivotally engages the forward end of the bolt and the receiver. To unlock the bolt, it is pivoted outwardly from the receiver to disengage the cross lug, and is then pulled rearwardly and thence forwardly to cock the rifle.
While this type of bolt action has some advantages, it has never been adapted to muzzleloading rifles or to center fire in line weapons.
It is therefore a principal object of this invention to provide a muzzleloading rifle having a pivotal reciprocal bolt for center firing.
A further object of this invention is to provide a muzzleloading rifle having a pivotal reciprocal bolt for center firing, and which has a safety lever located forwardly of the trigger mechanism.
These and other objects will be apparent to those skilled in the art.
SUMMARY OF THE INVENTION
A muzzleloading rifle has a stock, a receiver, a forwardly extending barrel, a removable breech plug in the rearward end of the barrel and forwardly of the receiver, and a trigger mechanism.
An elongated bolt member has a rearward end pivotally secured within the receiver and adapted to be pivoted from an aligned position within the receiver to an angular position outwardly through a slot in the side of the receiver. A transverse cross lug is mounted in a locking position within the receiver and has one end pivotally secured to the bolt so that when the bolt is pivoted outwardly from the receiver, the cross lug will be unlocked from the receiver to allow the bolt to be moved to a rearward position in the slot of the receiver. The bolt is operatively connected to an elongated striker pin in the bolt to pull the striker pin rearwardly against a compression spring when the bolt is moved forwardly to cock the striker pin.
The trigger mechanism operatively releasably engages and holds the striker pin against forward movement when the bolt is moved forwardly and thence pivoted laterally to resume an aligned position within the receiver.
