Phonograph

The Graphophone was the name and trademark of an improved version of the phonograph. It was invented at the Volta Laboratory established by Alexander Graham Bell in Washington, D. C., United States. Its trademark usage was acquired successively by the Volta Graphophone Company, the American Graphophone Company, the North American Phonograph Company, and finally by the Columbia Phonograph Company (known today as Columbia Records), all of which either produced or sold Graphophones.

It took five years of research under the directorship of Benjamin Hulme, Harvey Christmas, Charles Sumner Tainter and Chichester Bell at the Volta Laboratory to develop and distinguish their machine from Thomas Edison's Phonograph. Among their innovations, the researchers experimented with lateral recording techniques as early as 1881. Contrary to the vertically cut grooves of Edison Phonographs, the lateral recording method used a cutting stylus that moved from side to side in a "zig zag" pattern across the record. While cylinder phonographs never employed the lateral cutting process commercially, this later became the primary method of phonograph disc recording. Bell and Tainter also developed wax coated cardboard cylinders for their record cylinder. Edison's grooved mandrel covered with a removable sheet of tinfoil (the actual recording medium) was prone to damage during installation or removal. Additionally the Graphophones initially deployed foot treadles to rotate the recordings, then wind up clockwork drive mechanisms, and finally migrated to electric motors, instead of the manual crank on Edison's Phonograph. After the Volta Associates gave several demonstrations in Washington, D. C., businessmen from Philadelphia created the American Graphophone Company on March 28, 1887, to produce and sell the machines for the budding phonograph marketplace. which itself later evolved into Columbia Records. The Howe Machine Factory (for sewing machines) in Bridgeport, Connecticut, became American Graphophone manufacturing plant. Tainter resided there for several months to supervise manufacturing before becoming ill, but later went on to continue his inventive work for many years. The small Bridgeport plant, which initially produced three or four machines a day, later became the Dictaphone Corporation. In 1889, the trade name Graphophone began to be utilized by Columbia Phonograph Company as the name for their version of the Phonograph. Columbia Phonograph Company, originally established by a group of entrepreneurs licensed by the American Graphophone Company to retail graphophones in Washington DC, ultimately acquired American Graphophone Company in 1893. In 1904, Columbia Phonograph Company established itself in Toronto, Canada. Two years later, in 1906, the American Graphophone company reorganized and changed its name to Columbia Graphophone Company to reflect its association with Columbia. In 1918, Columbia Graphophone Company reorganized to form a retailer, Columbia Graphophone Company—and a manufacturer, Columbia Graphophone Manufacturing Company. In 1923, Louis Sterling bought Columbia Phonograph Co. and reorganized it yet again, giving birth to the future record giant Columbia Records. Early machines compatible with Edison cylinders were modified treadle machines. The upper works connected to a spring or electric motor (called Type K electric) in a boxy case, which could record and play back the old Bell and Tainter cylinders. Some models, like the Type G, had new upper works that were not designed to play Bell and Tainter cylinders. The name Graphophone was used by Columbia (for disc machines) into the 1920s or 1930s, and the similar name Grafonola was used to denote internal horn machines.
