This is a simple vertical engine with the engine bracket mounted on the firebox.
The vertical boiler is 55mm diameter x 77mm high. It has a single flue tube and is heated by a 3 wick meths burner. The top of the boiler has a safety valve and whistle. Steam is fed directly to the back of the port face of a single acting oscillating cylinder. Bore is 8mm and stroke 21mm. It is mounted in a simple but rather decorative folded brass bracket. The crankshaft has a simple crank at one end and a 54mm diameter spoked flywheel at the other. Next to the flywheel is an 8.25mm diameter pulley. As acquired, the original base is missing. This engine was originally supplied with one of two alternative bases; one cast and the other pressed steel. The firebox has tabs on the bottom which implies that it originally had a pressed steel base. I have temporarily mounted the firebox on a plain brass flat base until I can find an appropriate pressed steel one. The whistle bush had become unsoldered and was completely loose. Fortunately, the whistle was still attached so the bush did not fall down into the boiler and I was able to resolder it.| Make | CK Matsutoku |
