Joslyn rifle

The term Joslyn Rifle refers to a series of rifles produced in the mid-19th century. The term is often used to refer specifically to the Joslyn Model 1861/1862, which was the first mass-produced breech-loading rifle produced at the Springfield Armory.

History
Benjamin Franklin Joslyn was known as one of the most interesting gun designers during the U.S. Civil War, but he was known more for his constant clashes with sub-contractors and the Federal Government than he was for the quality of his arms. His disputes with the government lasted long after the Civil War had ended.

In 1855, Joslyn designed a breech-loading carbine. After successful tests, the U.S. Army ordered 50 of these rifles in 1857 in .54 caliber. The Army quickly lost interest in the rifle, but in 1858 the U.S. Navy ordered 500 of these in .58 caliber. Production problems resulted in only 150 to 200 of these rifles being delivered in 1861.

In 1861, Joslyn designed a modified version using a metal rimfire cartridge. The Federal Ordnance Department ordered 860 of these carbines, which were delivered in 1862. Most went to units from Ohio. In 1862, Joslyn received an order for 20,000 carbines. Delivery on these weapons started in 1863, but by the time the Civil War came to an end only about half of these had been delivered.

In 1865, Joslyn submitted two carbine designs for trial, both based heavily on the Model 1864 carbine. Despite ongoing difficulties between Joslyn and the U.S. Government, an order was placed for 5,000 of these weapons. Springfield Armory produced approximately 3,000 Joslyn rifles before hostilities ended.

After the war ended, the U.S. Government canceled all remaining contracts, claiming that the rifles failed to meet specifications. Litigation related to these contracts persisted for many years after the war ended.

In 1871, 6,600 carbines as well as 1,600 rifles that had been converted to use the .50-70 Government centerfire cartridge were sold to France for use in the Franco-Prussian War. Many of these were seized by Germany, sold to Belgium, and ultimately were converted to shotguns and shipped to Africa.

Design and features


The Model 1855 used combustible paper cartridges which were ignited by percussion caps. The breech was opened by means of a lever with an attached finger ring that ran along the wrist of the stock. The rifle version had a 30-inch barrel and an overall length of 45 inches. The carbine version had a 22-inch barrel and an overall length of 38 inches. The carbines purchased by the U.S. Army were .54 caliber, and the carbines purchased by the U.S. Navy were .58 caliber. A sword-type bayonet could be attached to the barrel.

The Model 1861 used metal rimfire cartridges, and had a laterally hinged block called the "cap" which enveloped the standing breech and could be swung open to the left when the locking catch was released. This design was refined in 1862 with the addition of cam surfaces which improved the cartridge seating and extraction. The Model 1861 was chambered for the Spencer .56-56 rimfire cartridge, and the improved Model 1862 used the Spencer .56-52 rimfire cartridge. The barrels were not designed to accept a bayonet.

The Model 1864 featured many small improvements and refinements to the Model 1862 design, and could fire either the Spencer .56-52 cartridge or a .54 caliber cartridge made by Joslyn.

The Model 1865 produced at Springfield Armory was based on the Springfield Model 1863 rifle musket, except that it used the Joslyn firing action instead of the Springfield 1863's muzzle-loading caplock system.
