Abstract: A squaring machine has an elongate generally cylindrical housing with an axially mounted motor at one end of the housing which rotates a shaft extending through the axis of the housing. The shaft is longitudinally moveable within the housing, and a non-rotatable inner sleeve is fitted around the shaft and is fixed for longitudinal movement with the shaft. The housing has a feed ring which is axially slidable but non-rotatably fixed around the tubular section, and a pin extends through a slot in the housing and the pin is connected to both the feed ring and the inner sleeve such that the feed ring, the inner sleeve, and the shaft move longitudinally in unison with respect to the housing. Rotation of a feed nut, which threadably engages the feed ring, causes axial movement of the feed ring along the tubular portion of the housing, and simultaneous axial movement of the shaft.

Abstract: A muzzle loading rifle has a cocking member which is rotatable about an axis perpendicular to the central axis of the barrel of the rifle and has a cam mounted on the distal end thereof. When the cocking member and the cam are rotated, the cam will move the hammer from a fired position to a cocked position. Second, a cylindrical primer holder having a transverse hole therethrough is provided to retain a primer charge. The primer holder may be rotated from a firing position to a safety position while retaining the charge enclosed within the receiver of the rifle. Third, a safety lever rotates about an axis perpendicular to the axis of rotation of the hammer sear from a first locked position to a second unlocked position. Movement of the safety lever to the second position unlocks the sear and allows the weapon to be fired.
