The Newcomen Beam Engine Kit

Newcomen Beam Engine
(Supplied only as a kit.)
This kit is to build a working model of the famous Newcomen Atmospheric Steam Engine that was the first engine to be used commercially to pump water from mines. The first installation was probably at Dudley,
England in 1712.

It was designed and built in the days when boilers could only withstand 15 psi and pistons and cylinders could not be made to any great accuracy. The engines power came from the weight of the pump rods raising the piston to the top of its stroke, the cylinder being filled with steam and then water sprayed into the cylinder to condense the steam to cause a vacuum. The pressure of the atmosphere then forced the piston down giving the engine its power stroke. Hence the term 'Atmospheric Engine'.

All in all, an attractive model of interest to the enthusiast and connoisseur.

At first, the engines were manually operated by cords but soon the valve gear was automated. This model incorporates the main features of the original automated engines. It has a Plug Rod that operates the Steam and Water Injection Valves, a Buoy which controls the power strokes of the piston and a combined Snifting Valve and Eduction Tank.


No Machining Required

The kit come complete with a full instruction manual.

The Main items of woodwork are pre finished and varnished.

Tools required:
Drill and Drill Bits
Junior Hacksaw
Soldering Torch and Solder
3mm Tap.

The model is not difficult to build (no machining is required) but you need patience to set up and operate the engine - you will need an oily rag and a supply of tea towels until you get the hang of it! Disastrous consequences used to occur with the original Newcomen Engine when operated by an unskilled operator.

It is not an accurate scale model of the original engine but serves to demonstrate the main features of an early Newcomen automatic engine with a water pump.

The boiler is heated by solid fuel tablets.

All in all, an attractive model of interest to the connoisseur.

The finished model stands 17" high x 11" long and 5" deep. Cylinder bore is 1" and maximum stroke is about 2" (variable)
