Steam Tank
The Steam Tank (Tracked) was an early U.S. tank design of 1918 imitating the design of the British Mark IV tank but powered by steam. The type was designed by an officer from the U.S. Army's Corps Of Engineers. The project was started by General John A. Johnson with the help of the Endicott and Johnson Shoe Company and financed by the Boston bankers Phelan and Ratchesky, costing $60,000 (US$ in ). Expertise was called in from Stanley Motor Carriage Company in Watertown, Massachusetts, that produced steam cars. The engines and boilers of two Unit Railway Cars were built in. Earlier fighting vehicles projects had employed steam power because petrol engines were not yet powerful enough; the Steam Tank however used it for the main reason that it was meant to be a specialised flame tank to attack pillboxes and the original design had this weapon driven by steam. When the main device to build up sufficient pressure became a auxiliary gasoline engine, the two main 2-cylinder steam ...

Flamethrower
A flamethrower is a ranged incendiary device designed to project a controllable jet of fire. First deployed by the Byzantine Empire in the 7th century AD, flamethrowers saw use in modern times during World War I, and more widely in World War II as a tactical siege weapon against fortifications. Most military flamethrowers use liquid fuel, typically either gasoline or diesel, but commercial flamethrowers are generally blowtorches using gaseous fuels such as propane; gases are safer in peacetime applications, because their flames have less mass flow rate and dissipate faster, and often are easier to extinguish when necessary. The military use of flamethrowers is restricted through the Protocol on Incendiary Weapons. Apart from the military applications, flamethrowers have peacetime applications where there is a need for controlled burning, such as in sugarcane harvesting and other land-management tasks. Various forms are designed for an operator to carry, while others a ...

Flame Tank
A flame tank is a type of tank equipped with a flamethrower, most commonly used to supplement combined arms attacks against fortifications, confined spaces, or other obstacles. The type only reached significant use in the Second World War, during which the United States, Soviet Union, Germany, Italy, Japan, and the United Kingdom (including members of the British Commonwealth) all produced flamethrower-equipped tanks. A number of production methods were used. The flamethrowers used were either modified versions of existing infantry flame weapons (Flammpanzer I and II) or specially designed (Flammpanzer III). They were mounted externally (Flammpanzer II), replaced existing machine gun mounts, or replaced the tank's main armament (Flammpanzer III). Fuel for the flame weapon was either carried inside the tank, in armoured external storage, or in some cases in a special trailer behind the tank ( Churchill Crocodile). Combat effectiveness In comparison to man-portable flamethrowe ...

Steam Road Vehicles
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Tanks Of The United States
The United States has produced tanks since their inception in World War I, up until the present day. While there were several American experiments in tank design, the first American tanks to see service were copies of French light tanks and a joint heavy tank design with the United Kingdom. In the interwar period there was reduced development due to the low expenditure on war material following the US isolationist policy and the financial position. In World War II, the US came to the fore with tanks designed for mass production and reliability reflecting the US position as the "arsenal of democracy". The U.S. has been greatly influential in the design philosophy, production and doctrine of tanks, and has been responsible for some of the most successful tank designs. World War I The U.S. entered the First World War on the side of the Entente Powers in April 1917, without any tanks of its own. The following month, in light of a report into British and French theories on tank ...

World War I Tanks
The development of tanks in World War I was a response to the stalemate that developed on the Western Front. Although vehicles that incorporated the basic principles of the tank (armour, firepower, and all-terrain mobility) had been projected in the decade or so before the War, it was the alarmingly heavy casualties of the start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead. In Great Britain, an initial vehicle, nicknamed Little Willie, was constructed at William Foster & Co., during August and September 1915. The prototype of a new design that became the Mark I tank was demonstrated to the British Army on 2 February 1916. Although initially termed "Landships" by the Landship Committee, production vehicles were named "tanks", to preserve secrecy. The term was chosen when it became known that the factory workers at William Foster referred to the first prototype as ...

Steam Wheel Tank
The Steam Wheel Tank was a U.S.-produced, prototype armoured fighting vehicle built by the Holt Manufacturing Company (now Caterpillar Inc.). Developed sometime between late 1916 and early 1917, it was the third tank to be designed in the U.S. The prototype was completed in February 1918 and was evaluated between March and May 1918 at Aberdeen Proving Ground. It performed poorly and was not developed further. Design Although it is often assumed that the vehicle was a tadpole configuration (with two driving wheels at the front), a senior Holt executive and the Aberdeen Proving Ground's report state that it was a delta configuration (with the large wheels at the rear), and that the vehicle drove like a conventional agricultural tractor.Crismon, p. 84 The two driving wheels were in diameter with treads, and a diameter roller, used for steering, was sited at the front. The rear wheels were made from pressed-steel sheet, the same as those used on Holt agricultural machinery of the ...

Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. A sponson's terminus is close to the cr ...

Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning "wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from pet ...

Steam Car
A steam car is a car (automobile) propelled by a steam engine. A steam engine is an external combustion engine (ECE) in which the fuel is combusted outside of the engine, unlike an internal combustion engine (ICE) in which fuel is combusted inside the engine. ECEs have a lower thermal efficiency, but carbon monoxide production is more readily regulated. Steam-powered automobiles were popular with early buyers. Steam was safe, reliable, and familiar. People had decades of experience with it in trains and boats, and even in experimental road vehicles. However, early steam cars required constant care and attention—and up to 30 minutes to start. Automated quick-firing boilers solved these problems, but not before more efficient gasoline engines dominated the market and made steam cars obsolete. The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ...

Watertown, Massachusetts
Watertown is a city in Middlesex County, Massachusetts, and is part of Greater Boston. The population was 35,329 in the 2020 census. Its neighborhoods include Bemis, Coolidge Square, East Watertown, Watertown Square, and the West End. Watertown was one of the first Massachusetts Bay Colony settlements organized by Puritans, Puritan settlers in 1630. The city is home to the Perkins School for the Blind, the Armenian Library and Museum of America, and the historic Watertown Arsenal, which produced military armaments from 1816 through World War II. History Archeological evidence suggests that Watertown was inhabited for thousands of years before European colonization of the Americas, colonization. In the 1600s, two groups of Massachusett, the Pequossette and the Nonantum, had settlements on the banks of the river later called the Charles, and a contemporary source lists "Pigsgusset" as the native name of "Water towne." The Pequossette built a fishing weir to trap herring at the ...
