The Graphophone was the name and trademark of an improved version of the phonograph. It was initially designed at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C., United States. It was co-invented by Alexander Graham Bell, Charles Sumner Tainter, and Chichester Bell in 1886.

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 Phonograh 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,[1][2] 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.[3] Tainter received a separate patent for a tube assembly machine to automatically produce the coiled cardboard tube cores of the wax cylinder records. The shift from tinfoil to wax resulted in increased sound fidelity and record longevity.

Besides being far easier to handle, the wax recording medium also allowed for lengthier recordings and created superior playback quality.[3] 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.[3]

Commercialization

[edit]

In 1885, when the Volta Laboratory Associates were sure that they had a number of practical inventions, they filed patent applications and began to seek out investors. The Volta Graphophone Company of Alexandria, Virginia, was created on January 6, 1886, and incorporated on February 3, 1886. It formed to control the patents and to handle the commercial development of their sound recording and reproduction inventions, one of which became the first Dictaphone.[4]

American Graphophone's 1888 wax cylinder graphophone. The machines were marketed for only a few years by American Graphophone and the North American Phonograph Company, but were superseded by Edison's 1888 'perfected phonograph' and its solid wax cylinders.

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.[5] The Volta Graphophone Company then merged with American Graphophone,[5] which itself later evolved into Columbia Records.[6][7] 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.[4]

Subsequent developments

Shortly after American Graphophone creation, Jesse H. Lippincott used nearly $1 million of an inheritance to gain control of it, as well as the rights to the Graphophone and the Bell and Tainter patents. He directly invested $200,000 into American Graphophone, and agreed to purchase 5,000 machines yearly, in return for sales rights to the Graphophone (except in Virginia, Delaware, and the District of Columbia).[3]

Soon after, Lippincott purchased the Edison Speaking Phonograph Company and its patents for US$500,000, and exclusive sales rights of the Phonograph in the United States from Ezrah T. Gilliand (who had previously been granted the contract by Edison) for $250,000, leaving Edison with the manufacturing rights. .[3] He then created the North American Phonograph Company in 1888 to consolidate the national sales rights of both the Graphophone and the Edison Speaking Phonograph.[3]

Jesse Lippincott set up a sales network of local companies to lease Phonographs and Graphophones as dictation machines. In the early 1890s Lippincott fell victim to the unit's mechanical problems and also to resistance from stenographers, resulting in the company's bankruptcy.[3]

A coin-operated version of the Graphophone, U.S. patent 506,348, was developed by Tainter in 1893 to compete with nickel-in-the-slot entertainment phonograph U.S. patent 428,750 demonstrated in 1889 by Louis T. Glass, manager of the Pacific Phonograph Company.[8]

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. The company Proceeded to make several smaller, cheaper Graphophones. Including the Columbia B in 1897 which sold over 250,000 units between 1897 and 1907. 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.[3][9][10]

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.

The Graphophone was an early phonograph-like device invented in the 1880s by , his cousin , and mechanic at the Volta Laboratory in , designed to record and reproduce sound using wax-coated cylinders for improved durability and audio fidelity over Thomas Edison's tinfoil-based of 1877. Development began in the early 1880s as Bell, leveraging his expertise, sought practical applications for recording beyond Edison's fragile tinfoil cylinders, which limited playback to a few repetitions and produced faint . By 1885, the team had experimented with wax-on-binder-board discs, capturing one of the earliest known recordings of Bell's voice on of that year, recovered noninvasively through optical methods in the Smithsonian's collection. The breakthrough came with the 1886 prototype, featuring reusable cylinders on cores that allowed up to five minutes of dictation—sufficient for two or three short business letters—and multiple playbacks without significant degradation, thanks to a floating mechanism that etched grooves more precisely. Named from the Greek roots graphō (to write) and phōnē (), meaning "sound writer" or "sound-pencil," the Graphophone was patented in 1886 and commercialized through the Volta Graphophone Company, initially targeting office dictation to boost workplace efficiency. The device's commercial models, such as those in the Smithsonian's holdings, incorporated a recording horn for capturing dictation and a playback mechanism that amplified sound via a diaphragm and needle tracing the cylinder's lateral grooves, representing a key evolution in mechanical sound reproduction. By , the Graphophone had spurred competition, prompting Edison to refine his own wax-cylinder , but the Bell-Tainter design's affordability—selling for as low as $10 in 1897—helped establish it in business and emerging entertainment markets, laying groundwork for the recorded through companies like . Its innovations in wax media and groove incising enabled the preservation of conversations, music, and voices, influencing modern audio technologies from to digital streaming services.

Invention and Early Development

Volta Laboratory Origins

In 1881, established the Volta Laboratory in , using the 50,000 francs from the Volta Prize awarded by the French government in 1880 for his invention. The laboratory served as a dedicated space for experimental research in sound recording, funded to support ongoing innovations without reliance on external sponsorship. The initial efforts at the Volta Laboratory centered on enhancing Thomas Edison's 1877 , which relied on fragile tinfoil-wrapped cylinders that wore out quickly after just a few plays, limiting its practicality for repeated use. Researchers sought to develop more durable recording surfaces to enable clearer, longer-lasting reproductions suitable for applications like dictation and message storage. From 1881 to 1886, the team conducted extensive experiments with alternative materials for recording media, prioritizing substances that balanced durability against sound fidelity. They tested wax-coated paper tapes, cardboard cylinders, glass discs coated with photographic emulsion, and brass discs embedded with green wax, evaluating how each affected groove depth, playback clarity, and resistance to degradation. These trials, involving prototypes modified from Edison's designs, marked a shift toward wax-based compositions that could capture and retain audio vibrations more effectively than tinfoil. By 1885, these advancements culminated in a prototype Graphophone, demonstrated through recordings of voices reciting counts, Shakespearean quotes, and nursery rhymes like "Mary Had a Little Lamb," which exhibited markedly improved clarity over prior tinfoil efforts. By late 1885, the team completed successful wax cylinder prototypes, showcasing the device's potential for recording both speech and music with reduced distortion and greater longevity. This work laid the groundwork for the Graphophone's evolution, driven by the collaborative input of Bell, his cousin , and .

Key Inventors and Contributions

The development of the Graphophone was spearheaded by , who directed the Volta Laboratory and supplied essential funding from the $10,000 Volta Prize (equivalent to 50,000 francs) awarded to him in 1880 for his telephone invention. As lab director, Bell offered conceptual guidance, drawing parallels from his telephone research to prioritize improvements in sound fidelity and durability for phonographic recording. His oversight ensured the project's alignment with practical applications for speech reproduction. Charles Sumner Tainter, a skilled mechanical engineer and instrument maker, played a pivotal role through his expertise in prototyping and design. In spring 1885, Tainter established a workshop at the Volta Laboratory to build experimental machines, including the first Graphophone prototype, and supervised the construction of six such devices that year. He innovated the floating system, which used a compliant cutting head to incise precise grooves into surfaces, reducing wear and enhancing playback quality. Tainter's mechanical contributions extended to the helical paper tube for cylinders, patented as U.S. Patent 374,133 in 1887, and he co-developed the core recording mechanism detailed in U.S. Patent 341,214, issued on May 4, 1886. Chichester A. Bell, a chemist and Alexander Graham Bell's cousin, contributed critical chemical advancements by formulating resilient wax compounds, such as mixtures of paraffin and beeswax, that supported multiple replays without groove degradation. These innovations addressed the limitations of earlier materials like tin foil, enabling clearer and more durable recordings. Chichester Bell collaborated closely with Tainter on the foundational Graphophone design, co-authoring U.S. Patent 341,214 for recording and reproducing speech and other sounds.

Technical Innovations

Recording and Cylinder Improvements

The Graphophone marked a significant advancement in sound recording technology by replacing Thomas Edison's fragile tinfoil-wrapped with durable wax-coated cardboard ones, enabling far greater replayability and sound fidelity. These new consisted of a hollow, helically wound paper tube core coated with a thin layer of , typically measuring 1 1/4 inches in diameter and lengths of 2, 4, or 6 inches, which allowed for recordings of up to five minutes on the longer . In contrast to Edison's tinfoil , which degraded after roughly 10 to 20 playbacks due to the soft metal's susceptibility to wear, the Graphophone's wax could withstand several dozen replays while maintaining clarity, as the wax surface resisted distortion from repeated stylus contact. This improvement stemmed from experiments at the Volta Laboratory, where Charles Sumner Tainter and Chichester Bell refined the medium to support practical dictation and musical applications. The wax formulation for Graphophone cylinders was a key innovation, composed primarily of a mixture of and paraffin, melted and applied uniformly to the core to achieve a thickness of about 0.1 to 0.2 millimeters. Tainter developed a specialized tube machine to automate this coating process, ensuring consistent thinness and adhesion that prevented cracking or uneven etching during use (U.S. Patent 428,646, 1890). This composition provided a harder yet malleable surface compared to tinfoil, allowing to incise fine grooves without excessive deformation, as detailed in the foundational recording patents: U.S. Patent 341,214 to Chichester A. Bell and Charles S. Tainter, and U.S. Patent 341,288 to Charles S. Tainter, both issued May 4, 1886. Unlike Edison's indenting stylus, the Graphophone employed a cutting stylus that shaved away wax to form the groove, enabling reusability and smoother incisions. In the recording process, sound waves from a voice or instrument were captured through a horn, causing a vibrating mica diaphragm to drive a stylus that etched variations into the wax cylinder's surface in a hill-and-dale (vertical) modulation pattern. The stylus, often a sharp steel point, created a helical groove approximately 0.003 inches wide and deep, with about 100 to 160 grooves per inch, tracing the sound's amplitude undulations perpendicular to the cylinder's rotation. To maintain consistent recording quality, the cylinder rotated at 120 to 160 revolutions per minute, powered by a hand crank or foot treadle mechanism that ensured steady surface velocity without the speed fluctuations common in early Edison models. These enhancements collectively reduced noise and improved frequency response, making the Graphophone suitable for clear voice transcription over extended sessions.

Playback Mechanism Enhancements

The Graphophone's playback system centered on a reproducer consisting of a attached to a lightweight arm that followed the hill-and-dale grooves incised into the wax cylinder, causing vibrations in an attached diaphragm that transmitted sound through an acoustic horn for amplification. Early models from employed a in this design, which traced the grooves with reduced wear compared to Edison's tinfoil due to the smoother wax surface. This configuration improved tracking accuracy and minimized during . The adoption of wax cylinders in the Graphophone enabled superior fidelity over Edison's tinfoil design through a cutting and improved groove formation, while both used hill-and-dale (vertical) modulation, capturing and reproducing higher frequencies with less for clearer voice and musical playback. Historical accounts note that these enhancements allowed for more articulate reproduction, addressing the muffled quality and limited tonal range of the original . Power for playback evolved from the 1886 model's foot mechanism, mounted on a sewing machine-like base to maintain steady cylinder rotation at dictation speeds. By the late , hand-crank options were introduced for portability, and electric motors—initially battery-powered DC units—became available in the 1890s to ensure consistent speed and eliminate manual effort. A key practical innovation was the shaving mechanism, typically an integrated or accessory blade that removed a thin layer of from used cylinders, permitting hundreds of times without significant degradation. This feature, operated via a revolving , extended the economic viability of the medium by allowing indefinite of cylinders after playback. Acoustic horns in Graphophone models varied from simple hearing tubes in prototypes to bell-shaped designs measuring 6 to 12 inches, which amplified output volume and could be adjusted by repositioning or swapping horns for different listening environments. These horns enhanced audibility, making the device suitable for both individual and small-group playback.

Commercialization Efforts

Formation of Early Companies

The Volta Graphophone Company was established on January 6, 1886, by Alexander Graham Bell and his associates, including Charles Sumner Tainter, to commercialize the sound-recording inventions developed at the Volta Laboratory. The company was formally incorporated on February 3, 1886, in Alexandria, Virginia. Its primary purpose was to secure patents for the Graphophone technology and license it to manufacturers, with initial capital drawn from Bell's personal funds, including the proceeds from his 1880 Volta Prize of 50,000 francs awarded by the French government for his telephone invention. In 1887, the associates formed the American Graphophone Company in , led by Tainter and a group of investors, to focus on the manufacturing aspect of Graphophone production. This entity merged with the Volta Graphophone Company later that year, consolidating patent management and production under a unified structure to streamline commercialization efforts. Early manufacturing occurred at a repurposed sewing machine factory in Bridgeport, where Graphophones were hand-built by skilled workers under Tainter's supervision. These initial units emphasized dictation functionality, utilizing the improved wax-cylinder recording process to serve office environments, particularly law firms, stenographers, and other businesses requiring efficient transcription tools. The machines were priced at around $150 for early business models, reflecting their specialized orientation.

Market Introduction and Distribution

The Graphophone was introduced to the market in 1887 by the newly formed American Graphophone Company, which focused on promoting the device as a reliable tool for business dictation to streamline office workflows and reduce reliance on stenographers. Demonstrations began that year, including a notable presentation in May at the St. James Hotel in New York to Edison representatives, highlighting the machine's improved wax cylinder technology for clearer recording and playback. Additional showcases targeted professional users, such as official reporters of the U.S. , who adopted the Graphophone for transcribing proceedings after testing its accuracy and ease of use. These efforts emphasized the device's potential to revolutionize documentation in legal, governmental, and commercial settings by allowing direct voice recording without intermediate transcription steps. Distribution adopted an exclusive territorial licensing model through the North American Phonograph Company, chartered in July 1888 to oversee leasing and sales of both Edison phonographs and Graphophones. By early 1889, this entity had established approximately 30 regional sub-companies across the , each granted monopoly rights to sell and service machines within defined geographic areas, primarily along the East Coast to facilitate rapid rollout and local support. Manufacturing ramped up at a , factory starting in July 1888, with an initial target of 300 units to supply these licensees, though production faced delays due to technical refinements. This structure ensured controlled expansion while providing maintenance and cylinder supplies directly to business users. Marketing centered on the Graphophone's durability for high-volume professional use, featuring reusable wax-coated cardboard cylinders that withstood hundreds of replays—far surpassing earlier tinfoil media—along with bundled supplies like blank cylinders and cleaning kits to support ongoing operations. Priced accessibly for businesses at around $150 for models like the Type K by , the campaign portrayed it as an indispensable aid for dictation, with early sales driven by endorsements from congressional reporters and initial placements in government s. By 1889, cumulative sales approached 1,000 units, concentrated in the U.S. East Coast through licensees like the Columbia Phonograph Company, which began distributing treadle-operated models for dictation and emerging musical applications. This focus on practical reliability helped establish the Graphophone as a staple in professional environments during its formative years.

Patent Disputes with Edison

Thomas Edison's foundational U.S. Patent No. 200,521, granted on February 19, 1878, broadly encompassed methods for recording and reproducing sound using a tinfoil-wrapped cylinder and a vertically undulating stylus that created hill-and-dale grooves. This patent positioned Edison to challenge subsequent innovations in sound recording, including those from the Volta Laboratory. When the American Graphophone Company began promoting its Graphophone device in 1887, Edison viewed it as an infringement, prompting him to file a competing patent application on November 26, 1887, directly disputing Charles Sumner Tainter's earlier filing of November 19, 1887, for key Graphophone improvements such as the floating stylus and wax cylinder recording. Tainter's patent (U.S. No. 393,190) was ultimately granted on November 20, 1888, after demonstrating priority through meticulous laboratory notebooks dating back to 1881, establishing the Graphophone's distinct inventions. The core legal conflict materialized in a series of infringement suits, with the American Graphophone Company initiating action against Edison's entities to protect its patents on wax-based recording and lateral-cut grooves, which differed fundamentally from Edison's vertical-cut tinfoil approach. In , the Edison Speaking Phonograph Company threatened litigation over Edison's core patents, leading to a settlement where North American Phonograph Company paid hundreds of thousands of dollars to resolve the claims. A pivotal case, American Graphophone Co. v. Edison Works, reached the U.S. for the District of , where on June 24, 1895, the court addressed equity practice issues amid ongoing disputes over cylinder technology and playback mechanisms. The Graphophone defense emphasized that their lateral groove system and durable wax media represented novel advancements not anticipated by Edison's original design, supported by experimental records and witness testimony from the Volta Laboratory. The protracted battles, spanning patent interferences and infringement claims from 1887 through the mid-1890s, culminated in a cross-licensing agreement in 1896 between Edison's National Company and the American Graphophone Company (including its affiliate, Columbia Phonograph). Under this deal, Edison acknowledged the validity of the Bell-Tainter patents in exchange for mutual access and royalty-sharing on technologies, effectively ending the adversarial phase and allowing both parties to commercialize improved machines without further interference. These disputes incurred substantial financial burdens, including multimillion-dollar settlements and legal expenditures that strained early industry players, though they ultimately validated the Graphophone's independent legitimacy and spurred refinements in sound recording standards.

Formation of the North American Phonograph Company

The North American Phonograph Company was incorporated on July 14, 1888, in New Jersey by Jesse H. Lippincott, in association with Thomas A. Edison's phonograph interests and the American Graphophone Company, to consolidate patent rights and streamline the commercial distribution of sound recording devices amid resolving legal conflicts over inventions like the phonograph and graphophone. Lippincott, who had acquired manufacturing licenses from both Edison and the Graphophone patentees earlier that year, served as the company's first president. The entity was capitalized at $6,600,000, reflecting ambitious plans to dominate the emerging market for dictation and recording technologies. Structured as a centralized trust modeled on the Bell Telephone Company's franchise system, the North American Phonograph Company granted exclusive territorial rights to over 30 regional affiliate companies, dividing the into defined districts—such as those for the Columbia Phonograph Company in the mid-Atlantic and the New England Phonograph Company—to handle local leasing and maintenance. These affiliates operated under strict guidelines, with the parent company supplying Edison and Graphophones, the latter incorporating key improvements like spring-driven mechanisms and wax cylinders for enhanced recording fidelity. This network aimed to prevent market fragmentation and further patent litigation by pooling resources from the involved parties. Operationally, the company emphasized a leasing model over outright sales, targeting business users with machines rented on a monthly basis for office dictation, while also exploring novelty and entertainment applications; Graphophones were positioned for professional transcription tasks, and Edison models for public demonstrations. By late 1889, it began producing and distributing blank and recorded cylinders through affiliates, with initial catalogs issued in January 1890 to support both commercial and experimental uses. The company's rapid growth led to overexpansion, exacerbated by unreliable coin-operated phonograph installations in public venues and insufficient demand for high-maintenance equipment, culminating in financial strain; it entered assignment for creditors in May 1891 and full in August 1894, with Edison emerging as the principal creditor. Despite its collapse, the North American Phonograph Company established foundational practices for leasing, regional distribution, and patent pooling that influenced the structure of the sound recording industry.

Later Evolutions and Legacy

Transition to Dictaphone and Coin-Operated Models

In the early 1890s, the American Graphophone Company acquired the Columbia Phonograph Company in 1893, with Edward Easton, formerly Columbia's president, assuming control after consolidation in 1895 under the Columbia banner. This shift allowed Columbia to fully integrate Graphophone manufacturing assets, transitioning from a licensing model to direct production and distribution of improved cylinder phonographs for business and entertainment markets. Technical advancements during this period enhanced the Graphophone's practicality and appeal. In 1898, Columbia introduced 5-inch "Grand" that enabled longer recordings, extending playback time to up to four minutes per , which supported more detailed dictation and musical selections. To expand into public entertainment venues, Columbia pursued coin-operated adaptations of the Graphophone. In 1893, patented a nickel-in-the-slot mechanism (U.S. Patent 506,348) that automated playback for two-minute , allowing unattended operation in parlors and arcades for a five-cent fee, directly competing with similar Edison phonograph models. These machines proved popular in nickelodeons and saloons, marking an early step toward automated audio amusement. The Columbia Type B model, introduced in 1897 and produced through 1907, exemplified these evolutions with its compact design, double-spring motor, and adaptability for both home listening and arcade installation via coin mechanisms. Over its decade-long run, the Type B—often marketed as the "Eagle" for its affordable $10 price—achieved widespread popularity, underscoring the Graphophone's growing consumer footprint before the rise of disc records. By the mid-1900s, Graphophone technology further specialized for office environments, culminating in the 1907 introduction of the trademark by the Columbia Phonograph Company. Building on earlier Graphophone dictation machines, later models incorporated electric motors for consistent speed and foot pedals for hands-free control during transcription, streamlining business workflows and establishing the device as a staple in professional settings.

Influence on the Recording Industry

The Graphophone's advancements in wax cylinder technology, particularly its use of a floating and lateral recording grooves, significantly influenced the shift toward flat disc records by improving sound fidelity and durability over earlier tinfoil methods. This wax-based approach inspired Emile Berliner's development of the gramophone in , which adapted similar principles to lateral-cut flat discs for more reproducible playback. The resulting disc format gained commercial traction, culminating in the formation of the in 1901, which combined Berliner's patents with enhanced spring-motor mechanisms to mass-produce gramophones and discs, dominating the early 20th-century market. In the business realm, the Graphophone's legacy persisted through specialized applications and record production. The , an evolution of the Graphophone's dictation-focused design, maintained dominance in office recording environments from the early 1900s until the advent of in the 1940s, enabling efficient voice transcription for professionals worldwide. Similarly, , which originated from the American Graphophone Company in the 1890s, reemerged in 1923 under the banner and pioneered the widespread use of 78 RPM discs, standardizing playback speeds and facilitating the electrical recording era that boosted music accessibility. The Graphophone fostered a cultural shift toward home entertainment by popularizing recorded sound in accessible formats, with coin-operated models installed in numerous U.S. locations such as saloons and arcades by 1900, which dramatically increased public exposure to and spurred sales of cylinders and early discs. The expiration of key Graphophone-related patents in the , including those held by the American Graphophone Company, removed for new manufacturers, accelerating widespread adoption of recording technology and enabling its integration into for live-to-disc captures and early sound films via synchronized disc systems in the . Echoing into modern times, the Graphophone's emphasis on enhanced fidelity through refined groove modulation and material durability laid foundational principles for subsequent audio , influencing the development of high-fidelity analog systems that informed digital compression algorithms, such as those preserving perceptual quality in formats like MP3.
