The Owen 2-b is a twin cylinder stationary engine; obviously inspired by the Mamod SE3 but with a flat base and other minor differences and using heavier materials. It is serial number 132.
It has two single acting oscillating cylinders. A pulley is mounted on the crankshaft adjacent to the flywheel. The engine has no reversing lever but it does have a throttle valve mounted on the top of the boiler. Also on the boiler are a safety valve and a whistle. The chimney, also mounted on the boiler, has the exhaust steam fed to it, via a pair of pipes from the cylinders, but not the burner exhaust. The burner is a perforated plate type spirit burner. The steam feed pipe passes under the boiler through the flame to provide a degree of superheating. The horizontal brass boiler rests on the firebox, held in place by a U shaped wire strap. The boiler dimensions are 2" diam. x 6" long and the cylinders 5/16" bore x 3/4" stroke. The pistons have oil retention grooves and the port faces have felt inserts to help keep them lubricated. The Base is flat with Meccano-standard holes around the corners. It sits on plastic feet, one in each corner hole. The engine was in new unused condition when acquired.| Make | Owen |
