Empire B31


This engine is a solidly built engine, typical of early Empire engines. The base and flywheel are cast iron. The engine frame appears to be cast bronze (?) and incorporates the cylinder, steam valve, throttle and whistle mounting in the one casting.

The nickel plated brass vertical boiler is 2 1/2" diameter and 6 1/2" overall height. The heating element is contained in a hollow in the bottom of the boiler. It is rated at 110V and is supplied through a 2 pin connector on the base. This is completely unshrouded and has no earth connection. They hadn't heard of H&S in those days :-) Because of the lack of earth connection, I have made up a three core cable with a crocodile clip on the earth wire to clip onto the engine's metalwork. There is a traditional water gauge glass on the side and a dummy chimney on top incorporating the safety valve.

Steam is fed through the hollow engine frame casting, through a throttle valve to the integral cylinder, which is 5/8" bore x 7/8" stroke. The valve gear is a simple non-reversing eccentric operating a cylindrical slide valve.

The engine has been restored and is in good condition, both mechanically and cosmetically
