The Warner & Swasey Company was an American manufacturer of machine tools, instruments, and special machinery. It operated as an independent business firm, based in Cleveland, from its founding in 1880 until its acquisition in 1980. Originally founded as a partnership in 1880 by Worcester Reed Warner (1846–1929) and Ambrose Swasey (1846–1937), the company was best known for two general types of products: astronomical telescopes and turret lathes. It also did a large amount of instrument work, such as equipment for astronomical observatories and military instruments (rangefinders, optical gunsights, etc.). The themes that united these various lines of business were the crafts of toolmaking and instrument-making, which have often overlapped technologically.

Historical timeline

Early career of the founders

In 1866, Swasey and Warner met as fellow apprentices at the Exeter Machine Works in Exeter, New Hampshire. Within a few years they went together to Pratt & Whitney in Hartford, Connecticut, which was one of the leading machine tool builders of the era. There they both rose through the ranks, with Warner rising to be in charge of an assembly floor and Swasey rising to be foreman of the gear-cutting department. There Swasey invented the epicycloidal milling machine for cutting true theoretical curves for the milling cutters used for cutting gears.

Partnership period (1880-1900)

In 1880, Swasey and Warner resigned from Pratt & Whitney in order to start a machine-tool-building business together. They investigated Chicago as a place to build their works, but they perceived the Chicago of 1880 as too far west and lacking a sufficient labor pool of skilled machinists. So they went to Cleveland, Ohio, where their company would stay for the next century. They worked together for 20 years without a formal corporate agreement, during which time their partnership's principal products were various models of lathes and milling machines. From the beginning, the partners built both machine tools and telescopes, which reflected their interests in toolmaking, instrument-making, and astronomy.

Reorganization into The Warner & Swasey Company (1900)

After nearly 20 years of successful growth, the partners realized that their business was growing enough that it should be given a formal corporate structure, so in 1900 they reorganized it under the official name of The Warner & Swasey Company.

Peak decades: 1900-1970

During this era, the company was well known in American industry. Its products, both turret lathes and instruments, played very prominent roles in the war efforts for both world wars.

Acquisition

Warner & Swasey took part in the transition to NC and CNC machine tools during the 1950s through 1970s, but like many machine tool builders during those decades, it ultimately was affected by the prevailing winds of merger and acquisition in the industry. It was acquired by Bendix Corporation in 1980.

Products

Telescopes

The first Warner & Swasey telescope, built in 1881, was sold to Beloit College for its new Smith Observatory and had a 9.5-inch lens made by Alvan Clark & Sons. Among the notable instruments the company built were the telescopes for Lick Observatory (1888, 36-inch, refracting); the United States Naval Observatory (1893); Yerkes Observatory (according to the 50th-anniversary book, this was a 40-inch refracting telescope completed in time for display at the World's Columbian Exposition of 1893, although its installation at Yerkes was apparently in 1897); and Canada's Dominion Astrophysical Observatory (1916, 72-inch, reflecting). In 1919, the company's founders donated their private observatory in East Cleveland, Ohio to Case Western Reserve University. Today's Warner and Swasey Observatory grew from that facility.

The company's 50th-anniversary book describes the firm's giant-telescope-building work as unprofitable overall but a labor of technological love.

Turret lathes

Warner & Swasey was one of the premier brands in heavy turret lathes between the 1910s and 1960s. Its chief competitors in this market segment included Jones & Lamson (Springfield, VT, USA), Gisholt (Madison, WI, USA), and Alfred Herbert Ltd (Coventry, UK).

Military instruments

Military instrument contracts were an important line of work for the company. The U.S. government referred many problems concerning such instruments to the company during the Spanish-American War (1898). Instruments produced included "range finders of several types, gun-sight telescopes, battery commanders' telescopes, telescopic musket sights, and prism binoculars". During World War I, three important kinds of instrument were produced: "musket sights, naval gun sights, and panoramic sights".

Construction Equipment

In 1946 Warner & Swasey Company acquired the patent rights to manufacture the Gradall telescopic boom excavator from the brothers Ray and Koop Ferwerda with their mamufacturing company, the FWF Corporation, of Beachwood, Ohio. The Gradall became a business of the new owner as the Gradall Division with operations in Cleveland. In July 1950, Gradall manufacturing operations were moved to New Philadelphia, Ohio where it continues, in 2011, as Gradall Industries, Inc. a global manufacturer of telescopic boom excavators and industrial maintenance machinery.
