The breechblock in a sliding block slides across the face of the breech to close it. The sliding action is perpendicular to the axis of the barrel. When the breechblock slides down to expose the breech, it is referred to as a falling-block, as used in the Sharps rifle. A sliding block is common in artillery. A vertical sliding block rises and ...
Ruger No. 1 single-shot falling-block rifle in .243 Winchester with custom barrel with action open. A falling-block action (also known as a sliding-block or dropping-block action) is a single-shot firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon and is actuated by a lever.

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. The spin imparted by the gun's rifling gives projectiles directional stability and increased range.
In a falling block or sliding block action, a solid metal breechblock "slides" vertically in grooves cut into the breech of the firearm and actuated by a lever. Examples of firearms using the falling-block action are the Sharps rifle and Ruger No. 1 .
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 ...
A series of interlocking doors closes and opens the path from the gunhouse to prevent a flash from traveling down the path to the magazine. 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 ...
Interrupted screw. 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] The system has also been used to close other devices, including the joint between helmet (bonnet) and breastplate (corselet) of standard diving suit helmets, and ...
The gun has a split sliding-block breech mechanism. One vertically sliding block holds a Crossley-type elastomeric obturation ring (which is necessary because the propellant charges are combustible cases or bags) and is locked for firing by a second block. When the second block falls, the first is released to open the breech. [6]
