The Lauson Frost King is the highest priced
engine on the market and has no competition.” So stated a
circa-1911 advertisement for the premier engine built by John
Lauson Mfg. Co. And though it sounds like hyperbole, it was
probably true. The Frost King had just taken the Gold Medal for the
second time in a Norwegian competition, and the official report
showed that the engine “will pay for itself in saving of fuel
running 700 days …”

In the Genes

Among the skilled craftsmen to help establish the new community
of New Holstein, Wis., were the five Lauson brothers, who started a
repair and implement shop.

One of those brothers was John Lauson. When his father, Detlaff,
died when he was 14, John joined the newspaper machine shop. Two
years later, he was so well-regarded that his uncle George Lauson
and John Optenberg asked him to join them in a three-way
partnership to start a machine repair shop together, using a
windmill for power. A year later, in 1885, the plant was destroyed
by fire.

Out of the ashes came the John Lauson and H. Optenberg and Co.
business, which specialized in repairing steam traction engines,
and also began making Uncle Sam steam traction engines. Twenty-five
were built by 1887. By this time, John was a first-class machinist
and repairman. At age 19, he bought out the Optenberg shares and
became sole owner of the renamed John Lauson Co.

Company employees were expected to be highly skilled, and it
showed in Lauson’s products. All boilers were riveted and caulked
by hand, producing a quality far better than the then-contemporary
standard of air hammering.

Now John Lauson began to forge the direction he wanted for his
own company. The Uncle Sam was dropped, but steam boiler
production, heavy machinery repair and the manufacturing of sheet
metal products were continued. But John Lauson had another idea: He
wanted to build gas engines. Perhaps as part of a greater plan, his
brother Henry had been working in a gas engine manufacturing plant
in Chicago. In 1895, Henry, Jacob Schmidt and John incorporated as
the John Lauson Mfg. Co., and began planning for the first Lauson
gasoline engine. Spark ignition was practically unheard of at the
time, so the first Lauson used hot tube ignition. A brass tube
extended up from the cylinder, which was heated via a blow torch.
Once drawn into the cylinder, the fuel mixture was ignited by the
heat of the tube.

Planning the new engine took many weeks. Patterns were made and
remade, then remade again, until finally everyone was satisfied.
Patterns were sent out, and in due time castings for the engine
arrived at the plant and “were wonderingly stared at and discussed
and eventually cussed by apprentices and machinists alike,” the New
Holstein Centennial Souvenir Booklet of 1948 says.

Initial Engine Success

Production methods of the era were slow, and the Lauson desire
for high quality probably made them even slower. The New Holstein
Centennial Souvenir Booklet says, “As work on the first engine
gradually progressed, the men in the shop feverishly and anxiously
awaited the outcome. At long last the engine was completed and
ready to start. The torch was lit! After a few trials, it gave a
hesitant cough, and then, somewhat reluctantly, started

By carefully adjusting the needle valve, Henry Lauson, who had
charge of the test run, was finally able to get the engine up to
its proper speed, the long exhaust pipe emitting whip-crack

John Lauson shouted to belt the engine up, and within minutes
that first Lauson gasoline engine was providing power to a line
shaft in the plant. This 4 HP engine weighed 1,140 pounds; by
comparison, later 4-1/2 HP air-cooled Lausons weighed just 85

Henry Lauson and worker H.N. Edens began to study gas
engineering in detail, and designed and built several other Lauson
engines in those early days. Eventually, an engine of 8-by-10-inch
bore and stroke, with electric ignition, was built, and named Frost
King. By 1904, it was a staple on the market, as was the striping
on the flywheels and bases.

Other engines followed, including tank-cooled engines of 5 to 20
HP sizes, including portable saw rigs. A pan-cooled system was
featured on Lauson 15 and 20 HP models.

In 1904, the Lauson company introduced a new type of engine that
led to a revolution in the field: open jacket, or hopper-cooled
engines. They were the first of their type on the market. The huge
demand pushed the firm to develop a variety of sizes of these
hopper-cooled Frost Kings. By 1916, Frost King hopper-cooled
engines were available in 12 sizes, from 1-1/2 to 28 HP, with the
same original design. Though the name “Frost King” hinted at
non-freezing, that was not true.

By 1916, Lauson added kerosene stationary engines from 3-1/2 to
28 HP to their line. These Frost Kings had a throttling governor
design, built-in magnetos, and redesigned cylinder heads and fuel
mixers to handle the low-grade fuels. A force-feed lubricating
device could also be added.

Some Frost Kings were huge. A 3-1/2 HP hand portable weighed
1,400 pounds, and the 28 HP portable tipped the scale at more than
3 tons. Frost King Jr. engines were another staple of the Lauson
line. These 1-1/2 HP engines used a drop forged crankshaft and
connecting rod as standard equipment, like their larger sisters.
Skid and portable models were available.

Other Lauson Engines

Lauson made portable screen-cooled engines with hit-and-miss or
volume governing, and instead of batteries, Sumter built-in
magnetos were standard equipment. A drop-forged cam and camshaft,
connecting rod, and nickel valve stems are all testaments to
Lauson’s commitment to quality

By 1916, the entire line of Lauson engines had become quite
sophisticated. The firm was building 2- and 4-cylinder vertical
models, as well as engine-generator sets for power houses. These
engines were of 35, 50 and 60 HP, which operated at 450 RPM. Eighty
and 100 HP engines in the series operated at 300 RPM.

Two-cylinder opposed models were built from 25 HP up and used
volume governing for precise speed regulation. They had huge intake
manifolds and mechanically-operated intake valves, with a
standard-included air compressor and other accessories for a
complete air starting system.

Lauson special electric plant engines had extra heavy flywheels
and an exceptionally sensitive governor. These engines also had
force-feed lubricators so they didn’t have to be watched for long
periods of time.

Lauson also built vertical engines. The 1905 line had 2, 2-1/2
and 4 HP verticals intended for light duty at home or in the shop,
using a fuel tank which held enough for two days of work.

Even though Lauson’s 1905 catalog downplayed oil cooling and
said water was far more effective, the company built at least one
oil-cooled engine.

The Town Rallies ‘Round

In 1907, New Holstein had a close call. The company had outgrown
its factory, and city fathers of Plymouth, Wis., tried to induce
John Lauson Mfg. Co. to move there, offering five years without
taxes. “However,” the New Holstein Centennial Sou-venir Booklet
says, “the people of New Holstein refused to stand idly by and
permit ‘their factory’ to move out of town. They subscribed to all
available preferred stock, and A.A. Laun Sr., presented free New
Holstein land where a new 100-by-200-foot factory was built.”

Without a foundry, engine castings had to be purchased
elsewhere, and many were large, heavy and expensive to ship. So in
1913 A.A. Laun Sr., along with John and Henry Lauson, brought
expert foundryman Edward Alyward to town and organized Alyward
Found-ry Co., which was in full production within a year, making
castings of all sizes for Lauson, and other companies as well. In
1915, John Lauson Mfg. Co. bought the company.

Tractor Time

That same year, 1915, the Lauson company decided to stop
building very large engines, and built high quality 15-25 and 20-35
tractors. Many Lauson tractors were sold in Europe. The 15-25 (also
called the 21-Jewel Kerosene Tractor) used an Erd 4-cylinder engine
with a 4-by-6-inch bore and stroke (later a Beaver 4-1/2-by-6); the
20-35’s Erd had a 4-3/4-by-6-inch bore and stroke.

Other sizes of Lauson tractors included:
• 12-25, with a 4-cylinder Lauson-Midwest 4-1/8-by-5-1/4-inch bore
and stroke;
• 15-30 and 20-40, both of which had the 4-cylinder Beaver,
4-3/4-by-6-inch bore and stroke;
• 20-35, with a 4-cylinder Erd, 4-3/4-by-6- inch bore and
• 16-32, with a 4-cylinder Beaver, with a 4- 1/2-by-6-inch bore
and stroke;
• 22-35 (also called the Lauson 65), with a 6-cylinder Wisconsin
and 3-7/8-by- 5-inch bore and stroke;
• 25-45, which used a 6-cylinder LeRoi, 4-1/2-by-6-inch bore and

Some of the models were specialized as “Thresherman’s Model” or
“Roadbuilder’s Special.”

Due to overextension of credit and competition in the 1930s,
Lauson could no longer compete. By 1937, production of Lauson
tractors was discontinued.

Founder’s Death

In 1922, 54-year-old John Lauson died very suddenly. His eulogy
in the April 21, 1922, New Holstein Reporter could not have
contained more adulation. He was “John” to all his workers; he
worked on the line with them; he took carloads of children into the
woods each spring to look at flowers; he was kind, unassuming,
modest, “possessed the very highest qualities of mankind,” the
article said. His death left a void that could not be filled.
Though the rest of the Lauson family picked up the slack, the
agricultural depression of the early 1920s and Great Depression of
the 1930s spelled the end for the New Holstein firm.

In 1930, the company developed the small 4-cycle, air-cooled
engine and became established in that field. Along with losses from
tractors, the development costs of the new engines helped push the
company into receivership. In 1935, it was reorganized as the
Lauson Corp. and sold to outsiders. Hart-Carter Co. of Peoria,
Ill., took over in 1941, and brought out a new line of 4-cycle
marine engines, both inboard and outboard.

Tecumseh Products Co. bought the Lauson Division in 1956, and in
1966, the Lauson Engine Division had 1,600 employees. The Lauson
Division of Tecumseh Products Co. still exists today.
