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 ...
When the breechblock is in the opened (bottom) position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case and reloading of an unfired cartridge. It is a very strong action; when the breech is closed, the receiver essentially becomes a single piece of steel (as opposed to other actions that rely ...
The abandonment of the Armstrong breech-loading design led Britain to begin a major program of building rifled muzzle-loaders to equip its fleet. The Armstrong 110-pound gun was succeeded by various RML 7 and 8-inch guns. 7-inch Armstrong breech-loaders under construction at the time of cancellation were completed as RML 64-pounder muzzle-loaders.
A breechloader [1] [2] is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the end of the barrel.
E.g. if the preponderance was quoted as 4 tons 2 + 1 ⁄ 2 cwt (4.2 t) as for the RML 17.72-inch "100-ton" gun, the breech end sat with that weight on its mounting, enough to ensure stability but not enough to hinder changes in elevation. The preponderance of British muzzle-loading guns was typically stamped on the end of one of the trunnions.
A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader which preceded it, has rifling in the barrel and is loaded from the breech at the rear of the gun.
In oil field tubing, buttress thread is a pipe thread form designed to provide a tight hydraulic seal. The thread form is similar to that of Acme thread [10] but there are two distinct threaded portions of differing diameters and profiles, the larger having a wedging profile, with a tapered sealing portion in between the larger and smaller diameters.
