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 ...
Falling-block action military rifles were common in the 19th century. They were replaced for military use by the faster bolt-action rifles, which were typically reloaded from a magazine holding several cartridges. [2] A falling-block breech-loading rifle was patented in Belgium by J. F. Jobard in 1835 using a unique self-contained cartridge. [3]
Meanwhile, the Prussian Navy had a 15 cm gun with double wedge breech and a weight of 60 Zentners (3,000 kg) changed for an increased charge. [18] This gun was tested in Fall 1868. In detail, it was a massive cast steel breechloader of 3050 kg including the double wedge breech block. The length of bore was 2,084 mm.

Interrupted screws are occasionally seen in loose gunpowder rifles, as this mechanism was historically one of the few practical ways to achieve a gas-proof seal with a breech-loading firearm that does not employ metallic cartridges. An earlier method was the use of a wedge to block the rear of the gun.
Krupp used the approach to slide a wedge through the rear part of the gun, the so-called sliding wedge breech block. Up till 1864 the Krupp sliding wedge breech called simple breech had an almost square diameter, only the corners of the breech hole were a bit rounded. That year Krupp invented the cylindroprismatic (halbcylindrischen) type of ...
Although designated as 28 cm (11 in), its actual caliber was 28.3 centimeters (11.1 in). It used Krupp's horizontal sliding-block, or "wedge", as it is sometimes referred to, breech design rather than the interrupted screw commonly used in heavy guns of other nations. This required that the propellant charge be loaded in a metal case (usually ...
Vertical Sliding Wedge Breech Block. Power rammed This gun used a 7.5 hp (5.6 kW) electric-hydraulic power rammer that was designed to ram a 93-pound (42 kg), 47.5 in-long (1.21 m) round (combined weight of projectile and propellant) into the chamber at any gun elevation in less than one second.
