Short Recoil Lock from Walther P38. Locked breech is the design of a breech-reloading firearm's action. This is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is ...
The driving spring assemblies held the lock frame against the carrier dog until the carrier was released by carrier catch which was pivoted by the incoming round. The springs then drove the lock frame assembly forward to operate the ejector, chamber the round and raise the breech block. Initial extraction occurred during recoil.
The earliest breech actions were either three-shot break-open actions or a barrel tip-down, remove the plug and reload actions. The later breech-loaders included the Ferguson rifle , which used a screw-in/screw out action to reload, and the Hall rifle , which tipped up at 30 degrees for loading.
A typical break-action, double-barreled shotgun. A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm.Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the ...
A turn bolt refers to a firearm component where the whole bolt without using a bolt carrier turns to lock and unlock. This is most commonly found in bolt-action firearms but is also found in some automatic firearms. The most common locking mechanism on rifles is a rotating bolt, which can be classified as a rigid type of bolt lock. Semi-rigid ...
The bolt drops down into receiver recess and locks on bolt closing. Tilting the bolt up and down locks-unlocks in the breech. This tilting allows gas pressure in the barrel from firing the gun to lower to safe levels before the cartridge case is ejected. For handgun design, the tilting barrel as used in the Browning, is a similar operating ...
Breech from Russian 122 mm M1910 howitzer, modified and combined with 105 mm H37 howitzer barrel. An interrupted screw or interrupted thread is a mechanical device typically used in the breech of artillery guns. It is believed to have been invented in 1845. [1]
In 1885 a locked breech, long recoil action was patented by the Britons Schlund and Arthur. [9] In a long recoil action, the barrel and bolt remain locked together during recoil, compressing the recoil springs. Following this rearward movement, the bolt locks to the rear and the barrel is forced forward by its spring.
