Description
This is a model of a bottle-frame vertical steam engine. Its date of manufacture is unknown, but similar designs were in use ca 1880. In the image of the model the bottle-frame is shown at the lower right. Atop the frame is the steam cylinder which is blue. Mounted on its left side is the steam valve with inlet and exhaust ports. The valve is operated by the two pushrods extending down to the eccentric gear on the shaft. The flywheel is seen to the left of the image. The second image shows the interior of the frame with the piston rod extending downwards from the cylinder to the connecting rod which turns the crank on the shaft.
Before the widespread use of electric motors, small high-speed steam engines were common for general light duty. Simple and dependable, such engines were cheap to build and easy to operate and maintain. They could be connected directly to pumps, generators, blowers and other machinery.
