Steam Engine Patent
This patent was granted to Isaac Briggs and William Longstreet for their steam engine design. The description outlines the construction of the engine, including a unique design for the boiler, two cylinders, and a condenser. This patent is part of the historical context of the Industrial Revolution.
This engine consists of a Boiler, two Cylinders and a Condenser, constructed in the following manner, viz.:
The Boiler
Consists of two metallic vessels, globular, or nearly so, placed one within the other, so as to leave a small interstice between, in which interstice the boiling water is contained. The inner vessel contains the fuel, the flame of which passes through a spiral flue winding round the outside of the outer vessel from the bottom to the top. The steam is conveyed by a pipe from the boiler into an interstice between
The Two Cylinders
Which are placed, horizontally, one within the other, from whence it is admitted alternately into each end of the inner cylinder, in which it impels a piston to vibrate both ways with equal force. It is also admitted alternately to pass from each end of the inner cylinder (all the communications, to and from which, are opened and shut by a single cock) by means of pipes into
The Condenser,
Which is a metallic vessel having a large surface in contact with cold water. The condensed steam or warm water is drawn out of it by a pump.
A patent granted by the Georgia Assembly to Isaac Briggs and William Longstreet for their steam engine, 1789.
