Thomas Savery
A History of the Growth of the Steam Engine
This patent is one of the earliest for a Steam Engine.

Note: Early English patents were not originally numbered but they were later assigned consecutive numbers that run from GB-1 of 1617 to GB-14359 of September 1852. From Oct 1852 until 1916, patents were numbered by the year and started at patent #1 at the start of each year in January. The patent number used in DATAMP represents the year of issue and the patent number. This patent is #GB-356 issued in the year 1698.

" A new invention for raiseing of water and occasioning motion to all sorts of mill-work by the impellent force of fire; which will be of great use and advantage for drayning mines, serveing townes with water, and for the working of all sorts of mills where they have not the benefit of water nor constant windes."

Savery's original patent of July 1698 gave 14 years' protection; the next year, 1699, an Act of Parliament was passed which extended his protection for a further 21 years. This Act became known as the "Fire Engine Act". Savery's patent covered all engines that raised water by fire, and it thus played an important role in shaping the early development of steam machinery in the British Isles.
