The object in the museum catalogue
This toy vacuum engine was purchased around 1915 and is made of cast iron, painted black. A vacuum engine refers to any kind of engine which derives its force from air pressure against one side of the piston, while also having a partial vacuum on the other side of it. This pressure differential can be the result of heat transfer, or mechanically produced by an external source.
