The United States Patent Office has issued more than 4,400 mousetrap patents. [3] The gun-powered mouse trap proved inferior to spring-powered mousetraps descending from William C. Hooker's 1894 patent. However, the 1882 patent has continued to draw interest–including efforts to reconstruct a version of it–due to its unconventional design. [4]
The Maynard carbine was a breech-loaded carbine used by cavalry in the American Civil War.The First Model was manufactured between 1858 and 1859. About 5,000 were made. In United States service it was distributed to the 9th Pennsylvania and 1st Wisconsin cavalry regiments, United States Marines aboard the USS Saratoga and the United States Revenue Cutter Service.
The guns, known as Maynards, were offered in .35 and .50 caliber, and could be purchased with interchangeable smoothbore shotgun barrels.

The Model 1874 Sharps (this model had been in production since 1871) was a particularly popular rifle that led to the introduction of several derivatives in quick succession. It handled a large number of .40 to .50 caliber cartridges in a variety of loadings and barrel lengths.
Derived from the .50-60-400 Joslyn, the cartridge was developed after the unsatisfactory results of the .58 rimfire cartridge for the Springfield Model 1865 rifle. The .50-70 Government cartridge used the Benét internal center-fire primer design and became the official cartridge of the U.S. military in 1866 until being replaced by the .45-70 Government in 1873.
