CK vert boiler horiz cylinder

1930s?





This is an unusual model for CK in that it has a vertical boiler and a separate single horizontal cylinder.

The boiler is a typical CK seamed vertical type, 55mm diameter x 80mm high. It has a single flue. The top end cap has a safety valve, steam feed pipe and a pressure gauge. The gauge carries the name Bassett Lowke and is definitely not original. I assume there should be a whistle in it's place. It is heated by a three wick meths burner.

Steam is fed directly to the back of the port face of the single acting oscillating cylinder. The cylinder is 8mm bore x 22mm stroke. The crankshaft has a simple crank at one end, a small 8.5mm diameter pulley at the other and a 52mm grooved & spoked flywheel in the centre. The whole assembly is mounted on a wooden base.

As acquired, there were a few minor faults. Apart from the missing whistle, the firebox mounting was loose on one side, the trunnion spring was broken and the safety valve was seized solid. I later found out that the safety valve was the wrong thread, although it appeared to be a CK one. It's probably one from a different engine of a different age. The correct thread is the same as the newer Wilesco ones, so I have fitted one of those for the time being. I have replaced the trunnion spring and secured the firebox fixing.
