they’re still out there

The quality of engines that continue to come out of the woodwork – quite literally in this case – continues to amaze me. The engine I’m referring to is a rare, circa-1915 15 hp Ohio, found in a long abandoned pump house next to an old inn on an island off the coast of Maine. And the reference to coming out of the woodwork? The wood-framed roof of the old pump house had to be surgically cut open – and then replaced – so the engine could be lifted out with a crane! Rescued by veteran engine man Mike O’Malley, the engine had been found some 30-plus years earlier by engine collector Alec Stevens. Buying it was another issue, the seller clearly intent on keeping it where it was. Undaunted, Alec routinely…

chasing thread tolerances

53/3/1: Thread standards Restorers of old engines and machinery inevitably run into problems involving thread or fastener standards, the most common being the 1/2-12 UNC standard that appears to have been used before World War I. I have not seen this standard on anything built after about 1918, when it changed to 1/2-13 UNC. In the British Whitworth threads, the 1/2-12 BSW continued until Whitworth was effectively abandoned in favor of metric in the early 1970s. Yet even standard sizes can vary slightly, which leads me to assume that many early manufacturers made their own taps and dies and didn’t always adhere to national standards. In addition to thread standards being “loose,” I have come across nuts or bolt heads with unusual hex sizes, sometimes made to the nearest 1/32 inch. A…

the tale of a 15 hp ohio

This all started about 30 years ago when my friend and fellow engine fan Alec Stevens first got married. His wife’s family was from an island off the coast of Falmouth, Maine, and when Alec would visit the island, he would ask around if there were any old engines. That brought him to an old pump house next to a large old inn on the island. The property had been divided up, and the pump house went with a little cottage that a lifelong islander owned. Over the next 30-plus years, Alec would visit the family – and of course the engine – and always inquire if it were available to be bought. “No” was always the answer. When the owner passed away, Alec let it be; the owner’s son…

rare engines: otto and westman

As brothers, Joe and Andy Schneider have family connections for their gas engine hobby. They both fell in love with gasoline engines at the same time after their father, John, took them to a show near Bradford, Minnesota, about 1990. “The next year my dad and Andy and I bought a couple of John Deere Model E 1-1/2 hp engines from a guy we knew,” Joe says. “It was neat seeing the engines, and when we got them running, I got bit by the bug.” Their friends in the suburbs didn’t get the engine idea, “My grandmother had an old farmstead where we did lots of different things we were interested in. I’m not sure our friends from those days still get why we collect gas engines,” Joe says. The Schneiders collected different…

the atkinson

I first learned about the Atkinson engine in a catalog of a book by Vincent R. Gingerly called Building the Atkinson Differential Engine. The Atkinson differential engine was developed by James Atkinson in England in 1882. At the time, Nikolaus Otto had full patent control for the 4-stroke engine design we all know about today. Atkinson knew that Otto’s design was not very efficient, and designed an engine that included all four strokes in one turn of the crankshaft instead of two, and all the strokes were all a different length. This is the Atkinson differential engine. This first engine design was not commercially successful. A few years later, in 1887, Atkinson designed another engine called the Atkinson cycle engine, which was a much better and more commercially successful design, featuring…

3 hp type z plugoscillator

The origins of the Fairbanks Morse Co. date back to 1823, when the company made cast iron plows and heating stoves. The early company, E&T Fairbanks, moved into producing scales, becoming a leading U.S. manufacturer. Employee Charles Hosmer Morse was instrumental in acquiring the Eclipse Wind Engine Co., and later became a partner in E&T Fairbanks, which became Fairbanks-Morse and Co. F-M started producing oil and naphtha engines in the 1890s before moving into kerosene and diesel engines, eventually becoming a dominant force in the fastgrowing engine industry. The Model Z was one of F-M’s most successful engines. First produced in 1916, more than a half a million Z engines were produced over the next 30 years. The Plugoscillator engine was made between June 1917 and 1919, but spark plug and…
