History
[edit]TheRemington Rolling Block rifleis one of the most successfulsingle-shotweapons ever developed.[clarification needed]It is a strong, simple, and very reliable action, that is not prone to be jammed by debris or with rough handling. It was invented by Leonard Geiger during theUnited States Civil Warand patented in 1863,[2]who (along with his partner, Charles Alger) negotiated a royalty deal with Remington when they put it into production as the so-called "split breech" action late in the war.[3]That design was re-engineered by Joseph Rider in 1865 and called the "Remington System".[4]The first firearm based on it, theModel 1865 Remington Pistol,was offered for sale to the United States Army and Navy in 1866. While the Army turned the design down, the Navy committed to purchase 5,000 pistols.
The first rifle based on this design was introduced at the Paris Exposition in 1867 and the United States Navy placed an order for 12,000 rifles.[4]Within a year it had become the standard military rifle of several nations, including Sweden, Norway, and Denmark.
Many earlier percussion rifles and muskets were converted to rolling-block designs in the interim before the development of more modern bolt-action designs.[5]
TheRemington M1867,[6]Springfield Model 1870,andSpringfield Model 1871rifles also used the rolling-block action.[7]
Barton Jenks rolling block action
[edit]A single-shot action developed by Barton Jenks fromBridesburg, Philadelphiaright after the Civil War was locked not by the hammer itself, but by a separate hinging piece on the breechblock; it was tested by the US military in 1866 but not adopted.[8][9]
