History
Revolving rifles were an attempt to increase the rate of fire of rifles by combining them with the revolving firing mechanism that had been developed earlier for revolving pistols. Colt began experimenting with revolving rifles in the early 19th century, and made the revolving rifles in a variety of calibers and barrel lengths. Colt revolving rifles were the first repeating rifles adopted by the U.S. Government, and an early model was used in the Seminole wars in 1838.[1]
The most widely produced revolving rifle was the Model 1855. This was produced in a rifle version as well as a shortened carbine. In 1855 it became the first repeating rifle to be adopted for service by the U.S. Military, but problems with the design prevented its use until 1857. The principal problem was that gunpowder would sometimes leak from the paper cartridges in field conditions, lodging in various recesses around the firing cylinder. Hot gas leaking from the gap between the firing cylinder and the barrel would ignite this powder, which would in turn, ignite all of the powder in the chambers waiting to be fired. This is known as a "chain fire" and was a relatively common failure with early percussion revolving firearms. When this happened with the Colt Revolving Rifle, a spray of metal would be sent forward into the left arm and hand of the user.[2]
This fault resulted in an understandable distrust in the weapon. Commanders attempted to get around the problem in a number of ways. The rifle had to be properly and thoroughly cleaned, since sloppy cleaning would leave residue behind that would increase the risk of a chain fire. Some commanders instructed their men to fire the weapon only while supporting it directly in front of the trigger guard or by holding the lowered loading lever, which moved their left hand out of the path of danger during a chain fire. Other commanders instructed their men to load only a single chamber, preventing any chain fires from occurring. Loading a single chamber at a time also reduced the weapon to a single shot weapon, effectively defeated the entire purpose of having a repeating rifle.[2]
Design and Features
Colt Model 1855 Carbine
The design of the Colt revolving rifle was essentially similar to revolver type pistols, with a rotating cylinder that held five or six rounds in a variety of calibers from .36 to .64 inches.[3]
The Model 1855, which was the most widely produced revolving rifle, was available in .36, .44 and .56 caliber. Four barrel lengths were available: 15, 18, 21 and 24 inches. A six shot cylinder was used if the caliber was .36 or the .44. If the caliber was .56, a five-shot cylinder was used.
The revolving rifle used percussion caps, like revolving pistols of the time. A cartridge consisting of powder and a lead ball were loaded into the front of the chamber, and were then compressed with a plunger that was located beneath the barrel. Once the cylinder's chambers were loaded, percussion caps were placed over the vent nipples at the rear of the cylinder. The weapon was now ready to fire. In addition to being susceptible to chain fire problems, the revolving cylinder design also tended to spray lead splinters into the wrist and hand of the user.[4] Revolving pistols did not suffer from this problem since the user kept both hands behind the cylinder while firing a pistol.
Some models could be fitted with sword style bayonets. In these rifles, the front sight would double as the bayonet lug.
Use
A combination of Colt revolving pistols and revolving rifles were used on the Pony Express by the eight men who guarded the dangerous run between Independence, Missouri, and Sante Fe. When doubts were expressed about the ability of these eight men to reliably deliver the letters on this run, the Missouri government declared that "these eight men are ready in case of attack to discharge 136 shots without having to reload. We have no fears for the safety of the mail." All mail deliveries on this route were completed safely.[5]
The U.S. Government had purchased 765 Colt revolving carbines and rifles prior to the Civil War. Many of these were shipped to southern locations and ended up being used by the Confederacy during the U.S. Civil War.[4] After the war began, the Union purchased many more rifles and carbines. Sources disagree over the exact number purchased, but approximately 4,400 to 4,800 were purchased in total over the length of the war.
The weapon performed superbly in combat, seeing action with the 21st Ohio Volunteer Infantry Union forces at Snodgrass Hill during the Battle of Chickamauga during the American Civil War.[6][7] The volume of fire from this weapon proved to be so useful that the Confederate forces were convinced that they were attacking an entire division, not just a single regiment.[3] Despite these victories of the weapon, the rifle's faults would prove fatal for the weapon. A board of officers met, and after evaluating the evidence, it decided to discontinue the use of the weapon. The weapons were sold for 42 cents a rifle, a fraction of the original purchase cost of 44 dollars each.[2]
Use in film
In 3:10 to Yuma (2007) the Mexican sharpshooter Campos (Rio Alexander) carries a Colt Model 1855 fitted with a full length telescopic sight and converted to fire metallic cartridges.[8]
In the John Wayne movie El Dorado, actor Arthur Hunnicut's character, Bull Harris, carries a Model 1855 revolving carbine as his main weapon.[8]
