A Double-Acting Six-Cycle Wonder/ the Mery Explosive Marks a Unique Page in Engine Development
The Mery as found by Bob Patty and photographed by Ken Beat sometime in the early 1970s. Note the spark plug fitted to the front of the forward cylinder in an attempt by Bob to get the Mery running.
Crankcase of Mery Number 2 found by Don and Judie Decker. Note the apparently original red paint and pin striping. Also clearly visible is the added rib under the crosshead to give this area of the engine more strength.
Roland Morrison's scale Mery, complete with intake linkage.
Mery Number 2 as it looks today. The Decker's hope to fabricate missing pieces.
The Mery's six strokes as drawn out by Roland Morrison. The piston is shown mid-stroke in all the diagrams. The exhaust valves are actuated via an eccentric and the intake and purge valves are atmospheric.
The only known picture of a fully set up Mery. Believed to be a copper cut, this originally appeared as an ad in the April 17, 1897 issue of the Livermore (California) Herald.
The Mery as it looks today in the ownership of Chuck and Peggy Schoppe. Note the counter-weight on the inside of the flywheel.
Maximus timer on Chuck and Peggy Schoppes' Mery.
Bob Patty (behind flywheel) with the Mery some time in the 1970s after Ken Beat got the Mery running and after painting it green and yellow.
Edison-cell batteries currently fitted to the Schoppes' Mery.
The Schoppe Mery as it looked when Ken Beal first saw it. At this point Bob Patty had given up on it, evident by the flywheel starting to settle into the ground.
Patent drawing of Mery shows intake and igniter actuation and exhaust valve mechanisms.
A close look at the exhaust valve chest on the Schoppe Mery shows slits for missing valve latching mechanism.
