Westinghouse Works, 1904 is a collection of American short silent films, each averaging about three minutes in length. The films were taken from April 18, 1904, to May 16, 1904, in Pittsburgh, Pennsylvania, and document various Westinghouse manufacturing plants. [1] They were made by G. W. "Billy" Bitzer of the American Mutoscope and Biograph Company, were shown at the Westinghouse Auditorium at the 1904 St. Louis World's Fair, and may have been made for that purpose. At least 29 films were produced and 21 remain in the collection which is now a part of the National Film Registry of the Library of Congress.
The films in the collection of the Library of Congress are:
Westinghouse executives commissioned Biograph to produce these films, intending to exhibit them to their subsidiaries and employees, thus making them some of the earliest existing examples of what are now called industrial films. They cannot be called documentaries because they were paid for and made according to guidelines set by the manufacturing company. In addition, they cannot be called commercials because they do not advertise individual products and were not exhibited widely to elicit sales.
The films were the first to use mercury vapor lamps (conveniently made by Westinghouse) to illuminate its shots, and they were also the first to use crane shots. Bitzer primarily used stationary cameras and fixed lenses, and he typically shot the films in a single continuous take.
Most films did not have title cards, so many of their names were assigned by the Library of Congress. [2]
The finished films were shown to Westinghouse employees in Pittsburgh, narrated by a speaker. They were later exhibited at the Louisiana Purchase Exposition in St. Louis (accompanied by organ music), and were received positively by audiences. [2]
George Westinghouse Jr. was an American entrepreneur and engineer based in Pennsylvania who created the railway air brake and was a pioneer of the electrical industry, receiving his first patent at the age of 19. Westinghouse saw the potential of using alternating current for electric power distribution in the early 1880s and put all his resources into developing and marketing it. This put Westinghouse's business in direct competition with Thomas Edison, who marketed direct current for electric power distribution. In 1911 Westinghouse received the American Institute of Electrical Engineers's (AIEE) Edison Medal "For meritorious achievement in connection with the development of the alternating current system". He founded the Westinghouse Electric Corporation in 1886.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy.
In electricity generation, a generator is a device that converts motion-based power or fuel-based power into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all the power for electrical grids.
The year 1904 in film involved some significant events.

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse and headquartered in Pittsburgh, Pennsylvania. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed CBS Corporation until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2005.
A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
The Pennsylvania Railroad's S2 class was a steam turbine locomotive designed and built in a collaborative effort by Baldwin Locomotive Works and Westinghouse Electric & Manufacturing Company, as an attempt to prolong the dominance of the steam locomotive by adapting technology that had been widely accepted in the marine industry. One was built, #6200, delivered in September 1944. The S2 was the sole example of the 6-8-6 wheel arrangement in the Whyte notation, with a six-wheel leading truck keeping the locomotive stable at speed, eight powered and coupled driving wheels, and a six-wheel trailing truck supporting the large firebox. The S2 used a direct-drive steam turbine provided by the Westinghouse Electric & Manufacturing Company, geared to the center pair of axles with the outer two axles connected by side rods; the fixed gear ratio was 18.5:1. Such design was to prevent energy loss and S2 achieved a mechanical efficiency of 97% which means only 3% of steam energy was lost within the propulsion equipment. The disadvantage of a direct-drive steam turbine was that the turbine could not operate at optimal speeds over the locomotive's entire speed range. The S2 was the largest, heaviest and fastest direct-drive turbine locomotive design ever built.
The Westinghouse Air Brake Technologies Corporation was an American company founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. Earlier in the year he had invented the railway air brake in New York state.
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or "variator" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is "a cross-field direct current machine designed to utilize armature reaction". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes. Since becoming popular in the mid-20th century, especially in trains and trams, the variety of applications and brake designs has increased dramatically, but the basic operation remains the same.
The Westinghouse Combustion Turbine Systems Division (CTSD), part of Westinghouse Electric Corporation's Westinghouse Power Generation group, was originally located, along with the Steam Turbine Division (STD), in a major industrial manufacturing complex, referred to as the South Philadelphia Works, in Lester, Pennsylvania near to the Philadelphia International Airport.
The Westinghouse Brake & Signal Company Ltd was a British manufacturer of railroad signs. Founded by George Westinghouse, it was registered as "Westinghouse Brake Company" in 1881. The company reorganised in 1920, associating with Evans O'Donnell, and Saxby and Farmer which merged to form the "Westinghouse Brake & Saxby Signal Company". The 'Saxby' would be dropped from their title in 1935.
In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity. The moving parts in a machine can be rotating or linear. While transformers are occasionally called "static electric machines", since they do not have moving parts, generally they are not considered "machines", but as electrical devices "closely related" to the electrical machines.
Wallace McCutcheon Sr. was a pioneer cinematographer and director in the early American motion picture industry, working with the American Mutoscope & Biograph, Edison and American Star Film companies. McCutcheon's wealth of credits are often mixed up with the small handful of films directed by his son, Wallace McCutcheon Jr. (1884–1928).
A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets.
Girls Taking Time Checks is a 1904 silent actuality film photographed by G. W. Bitzer for the Biograph Company in conjunction with Westinghouse Electric & Manufacturing Company. It was released by the Biograph Company.
