The Hughes breech-loading cannon 38.1mm gun was designed in 1861 and used by the Confederate States of America during the American Civil War. It was manufactured by the Street & Hungerford Company. It was a breech-loading cannon; the breech of the cannon is uniquely like a bolt-action but has no firing pin in its bolt.
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.
Breech-loading provides the advantage of reduced reloading time because it is far quicker to load the projectile and propellant into the chamber of a gun or cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and the tube has spiral ...
The above diagram shows the typical gun crew of a Civil War cannon. Each cannoneer was numbered and played an important role in the firing sequence when the order "Commence fire" was given: [43] Gunner: Gave the order "Load" to load the cannon and sighted it at the target. Number One: Sponged the barrel clean and rammed the round to the breech.
Muzzleloading artillery evolved across a wide range of styles, beginning with the bombard, and evolving into culverins, falconets, sakers, demi-cannon, rifled muzzle-loaders, Parrott rifles, and many other styles. Handcannons are excepted from this list because they are hand-held and typically of small caliber.
However, the advantages were clear, and breech-loading designs would grow to dominate rifle procurement after the Civil War. Many of the lessons learned by Hall would benefit designers of the next generation of breech-loaders such as the Sharps rifle (1848), Spencer carbine (1860), Henry rifle (1860), and others.
The nature of cannon operation often depended on the size of the cannon and whether they were breech-loading or muzzle-loading. English cannons of the late 14th century became mobile, while the largest cannon (such as the heavy siege cannon of the Ottoman Turks or the Jaivana cannon of India) required huge crews to transport and operate them.
The first version weighed 32 cwt, followed by the 35 cwt version which introduced a longer and stronger breech-piece. [5] A 32 cwt variant having a horizontal sliding-wedge breech instead of the Armstrong screw with vertical vent-piece was introduced in 1864 as an attempt to address the perceived weaknesses of the screw-breech design. It was ...
