This is an interesting arrangement of vertical oscillating cylinder engine.
The boiler is a vertical seamed brass type, 3.75" high x 2.25" diameter. It is heated by a 115V electric element. It has a dummy chimney which is purely cosmetic. It has a whistle and a filler cap, but no safety valve. It has a glass tube type water gauge. The integral engine bracket and port face is attached to the top of the boiler using a bayonet type fixing. The one fitted is a replacement, made of aluminium (?). The cylinder is a typical Weeden oscillating cylinder made of lead. It is single acting and, unusually, the active end is at the piston rod end. It is 5/16" bore x 7/16" stroke. The crankshaft is mounted in a tube going through the boiler, with a simple crank made of lead at one end and a 2.25" diameter flywheel at the other, also made of lead. When bought, the cylinder and it's port face block, were missing. A replacement block was made by a good friend and a second hand cylinder was obtained at the same time. The rest is in reasonably good original condition.| Make | Weeden |
