A disastrous fire in 1912 destroyed the old
Clark plant at Belmont. Instead of rebuilding in Belmont, the company moved to Olean,
NY. A new plant, which was the beginning of the present Olean campus, was erected.
In 1916, James Moore, Chief Engineer for Kerr
Steam Turbine Company leaves to start his own company at the other end of Wellsville, N.Y.
Moore Steam Turbine Company is founded.
In 1917 the Moore Steam Turbine Company produces
its first 250 HP turbine. Orders for another 151 multistage and 90 single-stage turbines
follow. Later, the product line expands to include much larger mechanical drive turbines
up to 6,000 HP and turbine generators up to 3,000 KW.
The years of 1918 and 1919 saw the entry of
Clark Bros. Company into the oil field business with a definite development program for
the rapidly growing industry.
In the 1920s: Significant Moore design
improvements and new developments made during this era include cam-operated automatic
nozzle control, two and four valve automatic extraction control, solid rotors and double
flow exhaust. These features, superior to competitive designs at the time, are still used
today.
In 1927, the Painted Post facility supplies
jackhammer drills and portable air compressors that will be used in the construction of
the Mt. Rushmore national monument in South Dakota.

In 1928 Worthington introduced the first angle
engine and compressor.

1930s: During the First World War, the
entire capacity of the Terry company was devoted to the war effort, operation being
maintained both day and night. Thereafter, and on through the 1930s, demand for Terry
turbines continued to grow.
In 1933, Ingersoll-Rand strengthened its line of
turbine driven centrifugal compressors by acquiring a comparable product line from General
Electric.
In 1937, the Moore Steam Turbine Company was
purchased by Worthington Pump and Machinery Corporation, a world-wide manufacturer of
reciprocating and centrifugal pumps, diesel and gas engines, air and gas compressors and
steam power equipment.
In 1938, Clark Brothers Company merged with the
S. R. Dresser Manufacturing Company of Bradford, Pa. Later, Dresser Industries was
incorporated under the laws of the State of Delaware in 1956 as a successor to the company
created by the consolidation of S.R. Dresser Manufacturing Company and Clark Bros.
Company.
During World War II, Dresser Clark designed and
built marine diesel engines for use in U.S. Army tugboats and tankers, assisted materially
by developing oxygen generating equipment for the Army Air Force, and continued to build
some of its regular line of engines and compressors for use in war plants. Through the
cooperation of all those working with Dresser Clark during the war years, the company was
able to contribute to the United States successful war effort. On five separate
occasions Dresser Clark received official government recognition for superior performance.

"Liberty" cargo ships in support of the war effort. |
In the 1940s: For Terry,
the industrial strength of America was again focused on building the tools of war. The
demand for Terry's rugged, reliable shipboard auxiliary turbines was virtually endless. 16
turbines were required for each battleship, 14 for each aircraft carrier and three or four
units each for destroyers and escort vessels. During this period, Terry produced 3,242
auxiliary turbines.
Terry turbines also provided power for such
critical industries as aviation gasoline refineries and synthetic rubber plants. Terry
even had its first contact with the nuclear industry as a supplier of pump drive turbines
for the government facilities in Oak Ridge, Tennessee, and Hanford, Washington.
With the outbreak of war, Worthington steam
turbines and turbine generator sets provided auxiliary power for many combat and transport
vessels of the U.S. Navy and Maritime Commission. The workforce doubled; the output
increased to 70 turbine generators and 100 mechanical drive turbines per month. Total
wartime production of 1,874 turbines with a rated capacity of 627,000 KW earned the
Wellsville Works five Army/Navy "E's" and a Maritime "M."
In 1944, Worthington acquired Electric Machinery
Mfg. Co. of Minneapolis, Minnesota, a manufacturer of electric equipment.
With the war over in 1945, Worthington developed
a line of high-speed two-pole generators which made considerably larger sizes of steam
turbine generator sets possible. New technology demanded mechanical drive turbines to
power centrifugal compressors and blowers in the range of 25,000 horsepower and at speeds
of 10,000 to 12,000 RPM. One of the outstanding developments was the triple flow exhaust
design, which enabled stresses to be kept within required limitations, while increasing
the output of the turbine.
In 1947, packaging (or skid
mounting) with process and utility systems included versus block mounting (with all work
done in the field) of integal and separable gas engine driven compressors began.
I-R integral engine compressors were packaged by
J.B. Beaird Co. of Shreveport, La. and separable, belt driven, model ES/ESH gas
compressors were packaged by Wilson Supply Co., Houston.
In 1947-48, Ingersoll-Rand and Clark designed
the first centrifugal compressors for natural gas transmission.
