The files include drawings and sketches, operating instructions on assembling and disassembling, black and white photographs, charts, and product literature. There are some documents that were not created by the Eisler Engineering Company. These documents include operating instructions and drawings from other companies that Eisler had a working relationship with. The instructions, [1934-1945?], arranged alpha-numerically, are operating instructions for machines manufactured by the Eisler Engineering Company. The instructions are labeled D-1 to D-800. These instructions should be used in conjunction with the other operating instructions for specific machines. For example, instructions D-1 are for Eisler machine No. 00, a coil winding machine
Series 5, Diagrams and Drawings, 1924-1960, is divided into two subseries, wiring diagrams and drawings. The wiring diagrams 1934-1956, are arranged by type and provide instructions and diagrams on how to connect wires for Eisler machines.

The litigation was heard in the U.S. District Court, Eastern District of New Jersey and U.S. Circuit Court of Appeals, Third District. GE brought suit against Eisler for infringement of two U.S. patents, #1,128,120 for manufacturing glass rods and forming spiders, and # 1,220,836 for a filament support wire inserting machine. Eisler allegedly infringed by manufacturing and selling a hook inserting machine.
There is one file folder of newspaper clippings about anti-trust in lamp manufacturing and specifically conclusions to the Opinion for the case United States of America vs. General Electric Company, 1953. GE, Corning Glass Works, N.V. Philips Gloeilampenfabriken, Consolidated Electric Lamp Company, Hygrade Sylvania Corporation, Chicago Miniature Lamp Works, and Tung-Sol Lamp Works, Inc., were found guilty and in violation of the Sherman Anti-Trust Act. GE, in particular, negotiated agreements through its wholly-owned subsidiary, International General Electric that divided the world lamp markets. This division permitted GE to have the U.S. market exclusively and bar foreign lamp manufacturers. The domestic licensees' growth was limited by GE to a fixed percentage of its own production and expansion so that over the years a licensee's share of the business was diminished. This restrained trade, and competition by GE unlawfully monopolized the incandescent electric lamp business.
A separate case involving Westinghouse Electric and Manufacturing Co. vs. Beacon Lamp Co., Leopold Rossbach, C. L. Shoninger, A.H. Moses, L.E. Whicher and J.T. Hambay from 1896 to 1898 is also documented through the brief for the complainant and a record of the case.
Patents, 1913-1931, are further divided into tube patents, 1924-1931 and tube patents assigned to Raytheon Company, 1913-1929. The patents were assembled by Eisler for reference.
Series 8, Photographs, 1944-1967, is further divided into six subseries: machines by number, CAMS; timers; jigs; transformers and electrodes; welders; welders, tips, jigs and fixtures; and miscellaneous. The series contains 8" x 10" black and white prints. Originally organized in three- ring binders, the photographs are arranged by machine number with further numerical identifiers. For example, Machine No. 103 is a glass lathe machine and No. 103-XL is a vertical glass lathe machine.
CAMS are curved wheels mounted on a rotating shaft and used to produce variable or reciprocating motion in another engaged or contacted part. They are used to produce or machine something. Tips refer to the remnant of the glass tubing through which the lamp was exhausted of its air (as well as filled with inert gases after the invention of the gas-filled lamp in 1912) and jigs are devices for guiding a tool or for holding machine work in place.
The majority of photographs document machinery; few employees are featured.

Biographical / Historical:
Charles Eisler (1884-1973) was born in Hungary to Adolph and Helen Eisler. Charles was the second child of nine: George, Emil, Michael, Leopold, Rudi, Franz, Emma and Lajos. Eisler completed his engineering and mechanical studies by the age of 17 and began an apprenticeship with a local factory. He became a licensed steam engineer and fireman of high pressure boilers. In 1902, he left Hungary for Berlin, Germany, with the goal to immigrate to the United States. In Germany, Eisler worked in a factory in Eberswalde, north of Berlin. The factory manufactured cast-iron pipe and machinery, and Eisler operated a crane loading barges near the factory. Eisler left Eberswalde and returned to Berlin to work as a toolmaker at Allgemeine Electricitäts Gesellschaft' (AEG). He arrived in New York City on the SS Potsdam/Stockholm (I) in November 1904. Because Europeans dominated the field of skilled mechanics and tradesmen in the United States, Eisler easily found employment in East Pittsburgh at Pittsburgh Westinghouse. In 1907, Eisler worked for Studebaker Metzger Motor Company as a tool-designer and tool room foreman.
Eisler returned to Hungary in the spring of 1912 where he took a job as a tool designing engineer with an American owned electrical firm, Standard Electric Company, in Újpest. He married Frieda Schwartz Eisler (d.1962) on December 24, 1912, in Budapest. They had four children: Charles Eisler, Jr., Martha (Eisler) Leff; Ruth (Eisler) Forest; and Constance (Eisler) Smith. In 1914, Eisler, his wife Frieda, and their newborn son Charles, Jr., returned to the United States. Eisler worked at the Westinghouse Lamp Company in Bloomfield, New Jersey, designing machines for building incandescent lamps with tungsten wire. At Westinghouse, Eisler held the position of chief engineer of the equipment division, and he completed the International Correspondence Schools course in mechanical engineering (1918). Eisler left Westinghouse in 1919 to work for Save Electric Corporation of Brooklyn, New York (an independent lamp manufacture), formed by Max Ettiger. At Save Electric, Eisler was equipment engineer superintendent and responsible for designing machines for the production of incandescent lamps.
General Electric (GE), Westinghouse, and RCA had a monopoly on modern incandescent lamp making machinery. The manufacture of lamps and tubes had moved from a low-rate, highly skilled craft work of Edison's Menlo Park to a high-rate, semi-skilled process dominated by GE and others. It was difficult for independent lamp manufacturers, such as Save Electric, to compete. The control and licensing of machinery patents was one method GE used to maintain a virtual monopoly on lamp manufacture throughout the first half of the 20th century. GE purchased Save Electric in 1920 to remove it from the incandescent lamp market. That same year, Eisler lost his job and started his own company, Eisler Engineering Company, to consult and manufacture equipment for producing electric lamps, television tubes, radio tubes, glass products, neon tubes, welding equipment and laboratory equipment. He established a machine shop at 15 Kirk Alley, Newark, New Jersey, where he redesigned many of his machines and drawings and started patenting. By 1924, Eisler's plant doubled in physical size and labor supply, with the radio tube industry peaking in 1929.1 However, the stock market crash of 1929-1930 severely impacted production, and Eisler never again saw the same growth. In 1929, Eisler sold a 49% interest in the company to Frank Bonner.
In June 1933, Eisler and others organized a group of independent manufacturers into the Incandescent Lamp Manufacturer's Association (ILMA). In response to the pressuring tactics of GE, Westinghouse and RCA, the group also documented every lamp maker who went out of business or that was bought by a monopoly member. The ILMA allowed members to pool their resources for patent litigation. "Eisler was the third leading outside supplier of lamp making machinery. It was not licensed by General Electric, and the unlicensed lamp manufacturers obtained most of their lamp making equipment from it. The Eisler equipment was less automatic and of considerably less speed than the machinery used by the General Electric group. However, it was considerably lower in price."2
Eisler Engineering Company was sued at least four times by GE between 1923 and 1928 for alleged patent infringement but won each case. The cases involved four United States patents owned by GE: Van Keuren #1,326,121; Mitchell and White #1,453,594; Mitchell and White #1,453,595; and Marshall #1,475,192. The last three patents address a process used in the manufacture of electric lamps known as "sealing in" of tip-less lamps. The plaintiff, GE, complained that Eisler, the defendant, was infringing. Several GE patents were declared invalid during the proceedings or were withdrawn, and Eisler's U.S. Patent #1,637,989 for tip-less lamps was upheld. See General Electric Company vs. Eisler Engineering Company, 20 F (2d.) 33 (C.C.A., 1927), 26 F (2d.) 12 (C.C.A., 1928), and 43 F (2d.) 319 (C.C.A., 1930). One of Eisler's strongest defenses was a 1916 article he published in Machinery on Tungsten Lamp Manufacture. Eisler defended his case not only for the interest of his own company but also for those who utilized his products as well as those who manufactured under a licensing agreement with Eisler Engineering Company.
In 1954, Charles Eisler, Jr., formerly vice president became president of Eisler Engineering Company, Inc., and Charles Eisler, Sr., became chairman of the board. In 1958, Eisler Senior officially stepped down. In the late 1970s, Eisler, Jr., sold the company to Kahle Engineering Company. Kahle, established in 1920 with its roots in the glass machinery business, provided equipment for the medical device, pharmaceutical, electrical and automotive industries. Today, Kahle focuses solely on the manufacture of assembly machines for medical devices.
Eisler was issued fifty-seven United States patents relating to the mass production of glass articles. His first patent was issued in 1916 (U.S. Patent # 1,209,650) for a turret attachment and his last was issued in 1958 (U.S. Design Patent # DES 182,796) for a spot welder/press type. Eisler received an honorary Doctor of Science degree from Bloomfield College in Bloomfield, New Jersey (1951) and was elected to life membership in the American Society of Mechanical Engineers (1952). He died on October 8, 1973 at the age of 89 in East Orange, New Jersey.
