An animal engine is a machine powered by an animal. Horses, donkeys, oxen, dogs, and humans have all been used in this way. [1] [2] [3] [4] An unusual example of an animal engine was recorded at Portland, Victoria in 1866. A kangaroo had been tamed and trained to work a treadmill which drove various items of machinery.

A military armoredcar is a lightweight wheeled armored fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties used to be assigned to light cavalry. Following the invention of the tank, the armored car remained popular due to its faster speed, comparatively simplified maintenance and low production cost. It also found favor with several colonial armies as a cheaper weapon for use in underdeveloped regions. During World War II, most armored cars were engineered for reconnaissance and passive observation, while others were devoted to communications tasks. Some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African Campaign.
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy.
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. The Industrial Revolution also led to an unprecedented rise in the rate of population growth.
A machine is any physical system with ordered structural and functional properties. It may represent human-made or naturally occurring device molecular machine that uses power to apply forces and control movement to perform an action. 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.
Mechanization is the process of changing from working largely or exclusively by hand or with animals to doing that work with machinery. In an early engineering text a machine is defined as follows:
Every machine is constructed for the purpose of performing certain mechanical operations, each of which supposes the existence of two other things besides the machine in question, namely, a moving power, and an object subject to the operation, which may be termed the work to be done. Machines, in fact, are interposed between the power and the work, for the purpose of adapting the one to the other.
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source.
The history of technology is the history of the invention of tools and techniques and is one of the categories of world history. Technology can refer to methods ranging from as simple as stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word techne, meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes which affect the environment around us.
A cotton mill is a building that houses spinning or weaving machinery for the production of yarn or cloth from cotton, an important product during the Industrial Revolution in the development of the factory system.
A steam donkey or donkey engine was a steam-powered winch once widely used in logging, mining, maritime, and other industrial applications.
A line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an industrial complex. The central power source could be a water wheel, turbine, windmill, animal power or a steam engine. Power was distributed from the shaft to the machinery by a system of belts, pulleys and gears known as millwork.
A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse engine as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs, donkeys, oxen or camels. Treadwheels are engines powered by humans.
A treadwheel, or treadmill, is a form of engine typically powered by humans. It may resemble a water wheel in appearance, and can be worked either by a human treading paddles set into its circumference (treadmill), or by a human or animal standing inside it (treadwheel). These devices are no longer used for power or punishment, and the term "treadmill" has come to mean an exercise machine for running or walking in place.
A horse engine is a machine for using draft horses to power other machinery. It is a type of animal engine that was very common before internal combustion engines and electrification. A common design for the horse engine was a large treadmill on which one or more horses walked. The surface of the treadmill was made of wooden slats linked like a chain. Rotary motion from the treadmill was first passed to a planetary gear system, and then to a shaft or pulley that could be coupled to another machine. Such powers were called tread powers, railway powers, or endless-chain powers. Another common design was the horse wheel or sweep power, in which one or several horses walked in a circle, turning a shaft at the center. Mills driven by horse powers were called horse mills. Horse engines were often portable so that they could be attached to whichever implement they were needed for at the time. Others were built into horse-engine houses.
B. Hick and Sons, subsequently Hick, Hargreaves & Co, was a British engineering company based at the Soho Ironworks in Bolton, England. Benjamin Hick, a partner in Rothwell, Hick and Rothwell, later Rothwell, Hick & Co., set up the company in partnership with two of his sons, John (1815–1894) and Benjamin (1818–1845) in 1833.
A portable engine is an engine, either a steam engine or an internal combustion engine, that sits in one place while operating, but is portable and thus can be easily moved from one work site to another. Mounted on wheels or skids, it is either towed to the work site or moves there via self-propulsion.
A steam wagon is a steam-powered truck for carrying freight. It is the earliest form of lorry (truck) and came in two basic forms: overtype and undertype, the distinction being the position of the engine relative to the boiler. Manufacturers tended to concentrate on one form or the other.
The city of Canterbury in Kent, England has been well served by mills over the centuries. These include animal engines, watermills and windmills.
John Kenneth Major ARIBA, FSA, popularly known as Ken Major was an architect, author and world authority on industrial archaeology, particularly windmills, watermills and animal powered machines. As an author, he was known as J Kenneth Major.
