Hielscher Steam Mill

c2016




This is a steam powered representation of a wind mill. It's design is typical of Lutsch Hielscher, with a glass boiler & boiler and tiny engine parts.

The boiler is a long necked flask shape; 39mm diameter at it's widest point and 120mm tall. It is heated by a wick type glass meths burner. It is supported by a tripod of brass strips, held together using three O rings used as rubber bands. This, I guess, is to minimise the risk of breaking the glass boiler stem.

The engine frame is connected to the boiler by a short length of brass tube. The tube is plugged into the top of the boiler stem with a silicone sleeve seal. The engine is a single oscillating cylinder, single acting, supported by the brass tube. The pivot is a very short stub, located in a hole in the port face. The cylinder is held against the port face using an O ring used as a rubber band. The cylinder is 3mm bore x 8mm stroke. The short crankshaft is fitted with a comparatively large (60mm diameter) flywheel.

The whole thing (empty) weighs just 67g, including the 9g burner! This is remarkably light cosidering it's 250mm height!
