Once you've seen an engine with 9-foot flywheels, how can you go back to one with flywheels a mere 7 feet high? That's what members of the Western Minnesota Steam Threshers' Reunion (WMSTR) group were thinking after their first sighting of a 1903 De La Vergne 125 HP oil engine.
As Jerome Swedberg writes in the 1976 Memories of Bygone Years, WMSTR's annual book, "Early in the spring of 1976, we heard rumor about a large, dual flywheel stationary engine for sale south of Little Rock, Ark. The flywheels were supposed to be about 7 feet in diameter." It was an 85 HP Muncie engine.
Just as they were about to set out, the late Harold Ottaway of Wichita, Kan., called to say he knew of a similar engine in Nevada, Mo., with 9-foot flywheels.
The group left for Little Rock from Fargo, N.D., at 9 a.m., drove all night, and arrived in Nevada, Mo., at 1 p.m. the next day. Jerome says, "We then located the W.F. Norman Sheet Metal Mfg. Co., a beautiful turn of the century brick building with a red tile roof, covering half a square block. Upon entering the engine room, we stood in awe. There in the middle of the room was the largest engine we had ever imagined seeing."
About a century before WMSTR's 1976 discovery of their 125 HP De La Vergne, John C. De La Vergne organized the De La Vergne Refrigeration Machine Co. The original intent was to manufacture refrigeration machines for breweries. His first machine had a 70-ton refrigeration capacity for Burr & Son Co. brewery in New York City. Soon the company was providing refrigeration for most of America's best known breweries, as well as some overseas. By the 1890s, De La Vergne ref- rigeration was used by hotels, restaurants, dairies, creameries, chocolate manufacturers, steamships and many more businesses.
After De La Vergne died in 1892, the business was taken over by Jacob Ruppert, who was interested in oil engines to meet the demand to power ice-making machines. "The result," said the 1936 issue of the Baldwin-Southwark Magazine, "was the first commercially-successful oil engine in the world." This forerunner of the diesel is now on display at the Smithsonian Institute in Washington, D.C., and was an improved design of the Hornsby-Akroyd oil engine, first produced in 1891, and invented by Akroyd Stuart of England. Sole American rights to manufacture the Hornsby-Akroyd oil engine were obtained by the De La Vergne Co. in 1893. In 1896, the company obtained the rights to produce Koerting gas engines.
During the 1890s, the company produced a pair of unlikely items: First, in about 1895, was the De La Vergne Hunting Trap, a gas-powered automobile that moved at the unheard-of speed of 10 MPH. "Only one of these automobiles was ever built," said Baldwin-Southwark Magazine, "as the board could see no market for this product." Second, after the company supplied New York City's Hippodrome with an ice manufacturing plant for the ice-skating rink, they came up with the idea of blowing cooled air under spectators' seats. Unfortunately, the audience didn't like it, and blamed their colds and illnesses on the cold air.
In 1903, De La Vergne Refrigeration manufactured a 125 HP dual flywheel oil engine for display at the 1904 World's Fair in St. Louis. That was where W.F. Norman Sheet Metal Works first saw it, and purchased it. At their Nevada, Mo., plant, they belted it to a line shaft to power machines that formed sheet metal, says Jim Withers of Osakis, Minn., owner of the De La Vergne engine and one of the WMSTR men who went to Nevada, Mo., to see the engine. "The first time we walked around that engine we knew we wanted to buy it," Jim says.
As Jerome Swedberg adds, "I'm sure it took five minutes to walk around the engine the first time, because there were so many unusual and massive parts to inspect." Measuring the flywheel, they discovered it was indeed more than 9 feet in diameter, with a 12-1/2-inch face. The cylinder bore was 26 inches, and the stroke was 38 inches. Valve heads were 10 inches in diameter, stems 1-1/2 inches in diameter, and the exhaust pipe was a foot in diameter, soaring 30 feet through the roof. After inspecting the behemoth, the parties agreed to a 60-day written option for $4,000, plus $500 to remove the exhaust pipe and repair the roof.
The lone exit door was 6 feet square, which meant, after careful measuring, Jerome says, that the engine base and cylinder would fit with less than an inch of clearance. "By enlarging the height of the door to 9 feet 5 inches, we thought we could wiggle the flywheels and (15 foot long) crankshaft through this opening at an angle."
Then the party headed out to Little Rock, where they found the Muncie engine just as it had been described: 7-foot flywheels, 85 HP, weighing 13 tons. "But this engine was sort of an anti-climax," Jerome says. "How could we be interested in an engine with 7-foot flywheels when we had just bought one with 9-foot flywheels weighing three times as much?" The answer was, they couldn't, so they returned home. Later, Warren O'Day, Curt Baxter, Jim and Jeff Withers and Jerome returned to Nevada, Mo., and began disassembling the big De La Vergne.
The small pieces, Jerome says, took up to five people to carry. The flywheels and crankshaft, which alone weighed 15 tons, were jacked up and removed from the main bearings, using rollers and a small come-along, until they were out of the building.
The next morning, the 20-ton base and cylinder were raised using 10-foot jack handles on each side. "The 2-inch bolts were cut off and rollers were placed under the base. We then proceeded to move it towards the door, again with the small come-along," Jerome says. The small parts were loaded in a U-Haul truck, and the rest by large crane on two semis, and were transported to the Rollag, Minn., WMSTR grounds. It was set up that summer on a cement foundation, with a lot of volunteer help.
Keven Withers, Jim's son, says, "We try to run it all four days of the show, starting it in the morning and running it all day, unless we run into problems." It has run every year since, except one year when Jim Withers was sick, and another year when it needed a series of repairs.
Some of those repairs included a cracked vaporizer chamber, which caused water to get into the fuel. One of the first years, the rod bearing burned out, but they managed to get it repoured and turned during the show. "We worked all night to get it repaired, and the engine was up and running the next day," Jim says.
Maintenance of the engine isn't a big problem, Jim says. "Before we enclosed the building, the engine needed quite a bit of cleaning before each show, and we had to check the oil holes and such to make sure they were open. There's really not a lot of other maintenance to it." Called an oil engine, it will run on diesel fuel or crude oil. Keven says, "If it's crude oil from out east, it's good enough to burn the way it is, but if it's from Texas or California where they have thicker crude, it has to be preheated to thin it out so it will pump through the injector nozzle. Pennsylvania crude has a consistency of about 10-weight oil and is very nice crude."
Starting the De La Vergne was a problem for years, Jim says. For many years, a WK-40 tractor and belt was used, but they worried about the dangers of the belt to people who watched and weren't inclined to move away when it was starting. "We'd always had it in the back of our heads that we wanted a separate way of starting it, and when we finally enclosed the building about six years ago, a good friend built a friction wheel for starting the engine. That made a lot of difference. When we had the cracked vaporizer chamber, we had a lot of trouble getting it started because the water in the vaporizing chamber would cool everything down and mix with the fuel and give us trouble. Now, though, it's generally easy starting."
At first, they were thinking of using an air starter, but a friend talked them out of it because in the old days the heads blew off of the engines when air was pumped in at 150 psi. And if the flywheels didn't move, the air worked as compression with the fuel and caused an explosion. "If the piston and flywheels didn't get moving, you'd have a pretty good explosion and blow the head off."
The biggest danger with a hot head oil engine is, if it's loaded up with fuel when it's started, it can have a tendency to run away, Jim says. "So you have to be prepared. If you hold one of the valves on a 4-cycle engine open, you can generally get it under control. The head needs to be heated up for starting and ignition; once the engine is started, the head will stay hot enough to keep it running.
This big De La Vergne isn't a true diesel engine, Keven says, as the head has to be heated with a torch, so it's called an "oil vaporizing engine," which takes the fuel and air mixture on the intake stroke, while a true diesel has fuel injected right at top-dead-center of the power stroke.
Gravity-fed cooling is accomplished via a 12-foot tall, 12-foot diameter water barrel. "There's a little sump tank in the floor, and the sump pump pumps the water back into the barrel. The engine will actually heat up all that water in the barrel." The biggest thing to remember with the De La Vergne in a climate like Minnesota's is to drain all the water before winter. It would just be way too expensive to put that much antifreeze into the barrel. After polishing the metal down with oil, the big machine weathers well over the winter.
Keven says he enjoys the size of the engine most of all, "and it runs good, too." He says people will often say they had an engine on the farm just like this one - or especially like one of the smaller farm engines at WMSTR - but they are remembering it through the eyes of a five- or six-year-old, and get it all out of perspective. "They remember their 8 or 10 HP engine had 72-inch wheels." Every once in a while, somebody will talk about the steam and gas engines of their youth, but that's happening less and less nowadays, Jim says.
People are pretty impressed with the engine when they see it, Keven says. "A lot of people feel that it probably has more horsepower than it does for its size, but mostly people want to know what it did in its working years. It usually draws a big crowd when we start it."
Keven, who is now in charge of the big machine at the yearly WMSTR show, says most of the literature on the 125 HP De La Vergne shows the engine with only a single flywheel, "So this one is probably the only one built with two wheels, because it was built for the World's Fair. At the W.F. Norman Co., it was used to make those decorative tin ceiling tiles."
Keven and his father returned to Nevada, Mo., six years ago to find that the old building that housed the De La Vergne was still there, and new tenants had started working with the old dies again, making decorative tin for restoration purposes. "Funny how things evolve," he says. "They're starting to make that tinwork again." The new owners were glad they stopped in, and were quite interested in knowing about the old De La Vergne. They only had the old photograph, the same as the one given to Jim in 1976 (at lower left), of the big machine in its original engine room, so they were anxious for more information.
Keven says nobody knew until after the big De La Vergne had been purchased, moved and set up that it's probably the only one of its kind - the largest single-cylinder, dual flywheel, open crankcase, 4-cycle, internal combustion engine running in the world.
"There could be some bigger with only one flywheel, and lots of steam engines are bigger, but no gas or diesel engine, that we know of, that has two flywheels."
