RARE & WELL-ENGINEERED BUILDER’S MODEL OF A MARINE CENTER FOUR-PILLAR, TWIN-PISTON BEAM STEAM ENGINE. This finely-constructed and well-presented model consists of an open-feetwork beam supported in the center by split double-columns supported by four pillars connected in one-piece pairs by horizontal cross-members. The beam is driven by a single vertical cylinder of approx. 1-1/2” bore x 2-3/4” stroke. The cylinder front-mounted valve chest with linkage to base-mounted cross-shaft and rod to a crankshaft-driven eccentric, single 8” dia. Serpentine-spoked flywheel and single 2-1/2” spoked, flat-belt drive pulley. Opposite end of crankshaft is attached to the opposite end of the beam by a double-tapered connecting rod. The beam drives two pistons mounted in-line on either side of the center pillar, each connected to the beam by a single connecting rod which transitions to a double rod on either side of the beam. Pistons are approx. 1” bore x 1-1/4” stroke. The iron or steel base and flywheel all appear to be machined, welded, and polished, vice cast. All of brass and polished steel construction mounted on a 2-pc walnut display operating base. Model operates perfectly on either steam or compressed air. SIZE: Operating base is 18” x 7-1/2”. Overall height from bottom of base to top of engine is 16’4”. CONDITION: Mechanically perfect. Entire model found in excellent, untouched, unpolished, original patina. 1-10548 (3,000-6,000)
