Bing 10/117/1


This model was made by Bing over a number of years. I have narrowed it down to 3 years by means of the logo found on the underside of the firebox.

This traction engine is quite small by modern standards. The boiler is 43mm diameter x 150mm long, externally. However, the internal length is almost certainly much shorter and I estimate it to be ~85mm. The burner is missing, but it appears to be a double wick type meths burner, with the tank and one wick inside the "firebox" and a second wick protruding forwards into a shielded spot under the front part of the boiler. There is a safety valve fitted at an angle on one side of the boiler and the steam outlet on the other. Steam is fed from the boiler via a simple oiler to the top of the cylinder valve chest.

The cylinder is mounted on a bracket on the top of the "firebox" and the crankshaft bracket is bolted to the front (dummy) end of the boiler, just behind a dummy chimney. The cylinder is hidden inside a cover but it's diameter appears to be ~8mm and the stroke is 13mm. The valve is a slide valve, operated by a fixed eccentric. It is not reversible. The crankshaft is a bent rod type, with a 56mm diameter spoked flywheel, incorporating a 10mm diameter pulley.This pulley should be connected to a 41mm diameter pulley fixed to one of the rear wheels. The rear wheels are 50mm diameter - smaller than the flywheel!

As acquired, is in need of some TLC. The burner and drive belt are missing, the oiler cap is seized solid, the whistle is damaged and does not unscrew from the boiler. There is a hole in the front end cap of the dummy section of the boiler. This should obviously have something fitted to it but I don't know what.
