Churchill Machine Tool Company
The Churchill Machine Tool Company Limited began as the manufacturing subsidiary#Lloyd-Jones, Lloyd Jones & Lewis p. 85. of the machine tool importers Charles Churchill & Company Limited founded in the early 1900s by US-born Charles Churchill (1837–1916).#Rolt, Rolt p. 177. Created out of the personal bankruptcy of Charles Churchill, the company developed to become one of the largest British importers of machine tools from the United States and a major manufacturer of such tools, initially under licence and later of its own development. The original business importing American machine tools into Britain began with Charles Churchill as sole proprietor and later as a partnership with two others. It became a limited company in 1889. In 1906 a separate company, The Churchill Machine Tool Co Ltd, was established with the purpose of adapting tools imported by Charles Churchill & Co. The former expanded, producing American tools under licence and then manufactured tools of its own de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamden, Connecticut
Hamden is a New England town, town in New Haven County, Connecticut, United States. The town's nickname is "The Land of the Sleeping Giant (Connecticut), Sleeping Giant".

Drill Bit
A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the ''shank'' in the chuck. Drills come in standardized drill bit sizes. A comprehensive drill bit and tap size chart lists metric and imperial sized drills alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section. Characteristics Drill geometry has several characteristics: * The spiral (or rate of twist) in the drill bit controls the rate of chip removal. A fast spiral (high twist rate or "compact flute") drill bit is used in high feed rate applications under low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morse Taper
A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the female socket, which has a matching taper of equal angle. Almost all machine tool spindles, and many power tool spindles, have a taper as their primary method of attachment for tools. Even on many drill presses, handheld drills, and lathes, which have chucks (such as a drill chuck or collet chuck), the chuck is attached by a taper. On drills, drill presses, and milling machines, the male member is the tool shank or toolholder shank, and the female socket is integral with the spindle. On lathes, the male may belong to the tool or to the spindle; spindle noses may have male tapers, female tapers, or both. Explanation Machine tool operators must be able to install or remove tool bits quickly and easily. A lathe, for example, has a rotating spindle in its headstock, to which one may wa ...

Gatling Gun
The Gatling gun is a rapid-firing multiple-barrel firearm invented in 1861 by Richard Jordan Gatling of North Carolina. It is an early machine gun and a forerunner of the modern electric motor-driven rotary cannon. The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing-reloading sequence. As the handwheel is cranked, the barrels rotate, and each barrel sequentially loads a single cartridge (firearms), cartridge from a top-mounted magazine (firearms), magazine, fires off the shot when it reaches a set position (usually at clock position, 4 o'clock), then ejects the spent casing out of the left side at the bottom, after which the barrel is empty and allowed to cool until rotated back to the top position and gravity-fed another new round. This configuration eliminated the need for a single reciprocating motion, reciprocating bolt (firearms), bolt design and allowed higher rates of fire to be achieved without the ...

Maxim Gun
The Maxim gun is a Recoil operation, recoil-operated machine gun invented in 1884 by Hiram Maxim, Hiram Stevens Maxim. It was the first automatic firearm, fully automatic machine gun in the world. The Maxim gun has been called "the weapon most associated with imperial conquest" by historian Martin Gilbert, and was heavily used by Colonialism, colonial powers during the "Scramble for Africa". Afterwards, Maxim guns also saw extensive usage by different armies during the Russo-Japanese War, the World War I, First and World War II, Second World Wars, as well as in contemporary conflicts. The Maxim gun was greatly influential in the development of machine guns, and it has multiple variants and derivatives. Design The Maxim gun featured one of the earliest recoil-operated firing systems in history. Energy from recoil acting on the breech block is used to eject each spent cartridge and insert the next one. Maxim's earliest designs used a 360-degree rotating cam to reverse the move ...

Hiram Maxim
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born British inventor best known as the creator of the first automatic machine gun, the Maxim gun. Maxim held patents on numerous mechanical devices such as hair-curling irons, a mousetrap, and steam pumps. Maxim laid claim to inventing the lightbulb. Maxim experimented with powered flight; his large aircraft designs were never successful. Circa 1904 he designed a highly successful amusement ride called the "Captive Flying Machine" to fund his research while generating public interest in flight. Maxim moved from the United States to the United Kingdom at the age of 41, and remained an American citizen until he became a naturalised British citizen in 1899, and received a knighthood in 1901. Birth and early life Maxim was born in Sangerville, Maine on 5 February 1840, into a family of French Huguenot origin. He became an apprentice Coach (vehicle), coachbuilder at the age of 14 and ten yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crinoline
A crinoline is a stiff or structured petticoat designed to hold out a skirt, popular at various times since the mid-19th century. Originally, crinoline described a stiff fabric made of horsehair ("crin") and cotton or linen which was used to make underskirts and as a dress lining. The term crin or crinoline continues to be applied to a nylon stiffening tape used for interfacing and lining hemlines in the 21st century. By the 1850s the term crinoline was more usually applied to the fashionable silhouette provided by horsehair petticoats, and to the hoop skirts that replaced them in the mid-1850s. In form and function these hoop skirts were similar to the 16th- and 17th-century farthingale and to 18th-century panniers, in that they too enabled skirts to spread even wider and more fully. The steel-hooped cage crinoline, first patented in April 1856 by R.C. Milliet in Paris, and by their agent in Britain a few months later, became extremely popular. Steel cage crinolines were ...
