T E Haynes Steam Engine

c1970s







In 1967, T E Haynes wrote a series of books entitled "Model Engineering for Schools". The first book in the series described the making of a steam engine. The books were used in metalwork classes and, hence, most of the engines to this design were made by pupils. This example is interesting in that it is layed out in mirror image to the pictures in the book! (The last photo on the left is taken from the front cover of the book.)

The boiler is painted with gold coloured paint so I can't see what it's made of, but the book specifies copper. It is 5 1/8" long x 2 1/2" diameter. It is a simple pot boiler with only a safety valve and small steam dome on top. There is no water level indication.

The boiler is heated by a meths burner of generally traditional design but with a distinctive wick holder in the form of a trough. The chimney is mounted on one end of the firebox and, in theory at least, should contribute some draught for the burner.

The steam feed pipe goes from the dome to the back of the engine port face, via an in-line compression type fitting. I has no regulator or lubricator.

The engine frame consists of three substantial blocks of steel in a U configuration, fixed directly on the sheet steel base. The engine itself is a single acting oscillating cylinder; 1/2" bore x a nominal 3/4" stroke (although this example is nearer 13/16"). A screw in the top end of the cylinder gives access for oiling the piston. The crank shaft has a disk crank on one end and a 2" diameter steel flywheel on the other.

Exhaust is fed to the base of the chimney.

The engine is reasonably well made, considering where it was made, although the port face and cylinder bore could be a little smoother. Paintwork could be mainly original but it has been touched up at some time.
