The Colt–Browning M1895, nicknamed "potato digger" because of its unusual operating mechanism, is an air-cooled, belt-fed, gas-operated machine gun that fires from a closed bolt with a cyclic rate of 450 rounds per minute. Based on a John Browning design dating to 1889, it was the first successful gas-operated machine gun to enter service.〔http://world.guns.ru/machine/usa/colt-browning-m195-e.html〕 ==Operating mechanism== Filed for patent in 1892, the M1895's operating mechanism was one of Browning's early patents for automatic rifles; he had previously been working on lever action rifles for Winchester such as the Winchester 1886. The M1895 uses a unique operating mechanism, which is quite similar to that of a lever-action rifle. The earliest prototype developed by Browning in early 1889 was a .44 caliber black powder cartridge rifle, weighing under 12 pounds. Operation was via a rear-hinged lever located under the barrel, which operated the action when swung downwards and rearwards. The lever was actuated by the muzzle blast operating upon it.〔 The bolt is a rear-locking tilting bolt, the first of its kind to be used on a machine-gun.
