Device for stripping cartridges
Applicant has disclosed a method and apparatus to enhance feeding cartridges into the receiver of a bolt-action repeating rifle, from a detachable magazine. In the preferred embodiment, Applicant's invention strips the cartridges from the magazines and feeds the cartridges into the chamber by a spring-activated hinged flap, pinned in a mating recess in a breech bolt head, adjacent a well opening and the inserted magazine. The flap is biased by a spring, which tends to lower the flap away from the breech bolt head, when the breech bolt is in a retracted position. As the breech bolt is pushed forward, the flap engages a rim of the next cartridge to be fed from the magazine and pushes the cartridge out of the magazine, over a feed ramp of the magazine, towards the rifle's chamber. The flap raises, against spring pressure, as it contacts a feed ramp of the receiver, allowing the breech bolt to enter the locking area of the receiver.
1. A method comprising:
a. inserting a detachable multi-stack magazine, with held cartridges, into a magazine well opening of a receiver of a bolt-action repeating rifle;
b. removably attaching the inserted magazine to the receiver; and
c. assisting stripping the cartridges from the magazine and assisting feeding the cartridges into a firing chamber of the bolt-action repeating rifle, via the following successive steps:
i. pushing a breech bolt head forward from a fully retracted position adjacent the well opening and the inserted magazine;
ii. lowering a distal end of a spring-biased hinged flap, pinned in a mating recess in a lower portion of the breech bolt head, by spring biasing the flap away from the recess as the breech bolt head moves forward from the fully retracted position;
iii. as the breech bolt head continues to move forward, engaging the distal end of the spring-biased flap with a rim of a next cartridge to be fed from the magazine into the firing chamber of the rifle, whereby the flap pushes the cartridge out of the magazine, over a feed ramp of the magazine, towards the firing chamber; and
iv. as the breech bolt head moves further forward, raising the distal end of the flap, against spring pressure, into the mating recess in the breech bolt head as the distal end contacts a feed ramp of the receiver, allowing the breech bolt head to enter a locking area of the receiver.
2. In a bolt-action repeating rifle of the type having a receiver, a firing chamber, a manually moveable breech bolt, a breech bolt head attached to the breech bolt, and a magazine well opening in the receiver for receiving a detachable double-stack magazine, the improvement comprising:
a. the detachable double-stack magazine, loaded with cartridges, inserted into the well opening of the bolt-action repeating rifle and removably attached to the receiver; and
b. an assistance mechanism for stripping the cartridges from the double-stack magazine and for feeding the cartridges into a firing chamber of the rifle, wherein the assistance mechanism comprises:
i. a spring-biased flap hinged in a mating recess, in a bottom of the breech bolt head, adjacent the well opening in which a magazine is inserted;
ii. a spring which tends to lower a distal end of the flap away from the mating recess in the breech bolt head, when the breech bolt head is in a retracted position;
iii. the distal end of the spring-biased flap, when the breech bolt head is pushed forward from the retracted position, lowers and then engages a rim of a next cartridge to be fed from the magazine into the firing chamber, pushing the cartridge out of the magazine, over a feed ramp of the magazine, towards the firing chamber; and
iv. the distal end of the flap raises, against spring pressure, as the distal end of the flap contacts the feed ramp of the receiver, allowing the breech bolt to enter a locking area of the receiver.
