Billinghurst Requa Battery
The Billinghurst Requa Battery gun was an early rapid-fire gun used during the American Civil War. It was invented by a Dr. Josephus Requa (1833–1910), a dentist by profession, who had at the age of 16 spent three years as an apprentice to William Billinghurst (1807–1880), a New York riflemaker. Design The gun consisted of twenty-five heavy .58 caliber rifle barrels, each long and mounted together in a secure frame, which could be elevated for range. The frame was then mounted on a two-wheeled carriage. Ammunition was loaded as a long magazine of twenty-five rounds, which were fired by a single percussion cap in a single volley. With a crew of three, it could be reloaded and fired seven times a minute, giving a rate of fire of 175 rounds per minute. The .58 caliber bullets were conical and weighed approximately one ounce. It was also possible to adjust the spread of the guns to make them diverge for use at close range. History In 1861 on the suggestion of an Albert Ma ...

Machine Guns Of The United States
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control compone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Cold Harbor
The Battle of Cold Harbor was fought during the American Civil War near Mechanicsville, Virginia, from May 31 to June 12, 1864, with the most significant fighting occurring on June 3. It was one of the final battles of Union Lt. Gen. Ulysses S. Grant's Overland Campaign, and is remembered as one of American history's most lopsided battles. Thousands of Union soldiers were killed or wounded in the frontal assault of June 3 against the fortified positions of Confederate Gen. Robert E. Lee's army—an action that intensified criticism of Grant's perceived indifference to heavy casualties. On May 31, as Grant's army once again swung around the right flank of Lee's army, Union cavalry seized the crossroads of Old Cold Harbor, about 10 miles northeast of the Confederate capital of Richmond, Virginia, holding it against Confederate attacks until the Union infantry arrived. Both Grant and Lee, whose armies had suffered enormous casualties in the Overland Campaign, received reinforc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
