Answer» (a) Textile industry: - In the year 1738, John Kay made and patented the ‘flying shuttle’ which increased the speed of weaving.
- The ‘spinning jenny’, a spinning frame with multiple spindles were made by James Hargreaves in England. It reduced the amount of labour and time of production.
- In the year 1769, Richard Arkwright made a more advanced spinning frame. It could produce yarns much faster.
- Samuel Crompton invented the ‘spinning mule’ in 1779 C. E.. This machine increased the speed of producing cloth two hundred times.
- In 1785, Edmund Cartwright invented the power loom.
- In 1793, a machine called the ‘cotton gin’ was introduced. This machine separated cotton seeds from cotton fibres at a greater speed.
(b) Metallurgy: - England had a number of iron mines.
- Therefore, it was necessary to advance the technique of smelting iron to acquire purified iron from it.
- The fuel for iron furnaces was replaced from wood to coal.
- Special machines were made to keep the furnaces at a set temperature and to maintain their aeration.
- In 1865, the process of producing steel from molten iron was invented and the nature of the iron industry underwent a major transformation.
- At about the same time, a method was adopted to pour the molten metal into casts for making iron bars (e.g. rails).
