Developed in Paris and patented in the U.S. in 1862, Alphone Jarre's "breech-bar" system used a horizontal arrangement of pinfire chambers to supply repeating fire, which could be put to use on pistols, rifles, and even cannons. In operation, the bar is pre-loaded with 10 pinfire cartridges, all secured in place with a spring-retained bar, and is then advanced from chamber to chamber left to right by a push arm connected to the double action trigger.
