Computers & Business Machines

Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.

The museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. Computers range from the pioneering ENIAC to microcomputers like the Altair and the Apple I. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

The Blickensderfer Model 8 typewriter was manufactured by the Blickensderfer Manufacturing Company of Stamford, Connecticut beginning in 1908.
Description
The Blickensderfer Model 8 typewriter was manufactured by the Blickensderfer Manufacturing Company of Stamford, Connecticut beginning in 1908. The Blickensderfer was advertised as having one quarter of the parts that other typewriters used, allowing for easier operation, maintenance, and repair. Other features include a tabulator and a scaled with slots for carriage stops. Blickensderfer typewriters also had a patented type action using their patented “type wheel,” a metal wheel containing all the characters which would rotate and strike the paper to create the inked mark. The type wheel allowed for easier type alignment, less jamming, and an easier way to change type fonts. The simplicity of the Blickensderfer made it portable, and this model had a wooden cover with a leather handle for easy carrying. While QWERTY keyboards could be ordered, by default most Blickensderfer typewriters eschewed the QWERTY keyboard in favor of a “Scientific” keyboard that put the most used letters “D, H, I, A, T, E, N, S, O, and R” on the bottom row nearest the space bar to minimize hand movement.
George C. Blickensderfer founded the Blickensderfer Manufacturing Company in Stamford, Connecticut in 1893. The Blickensderfer Manufacturing Company produced nine different models of typewriters, including an electric typewriter, and operated until George Blickenderfer’s death in 1917. The company was reformed as the Blick Typewriter Company for a few years before the Blickensderfer patents and designs were sold and manufactured by a variety of different companies.

This Remington Standard Model Number 6 typewriter was manufactured by the Remington Standard Typewriter Company around 1894.
Description
This Remington Standard Model Number 6 typewriter was manufactured by the Remington Standard Typewriter Company around 1894. The Model Number 6 contained many improvements to Remington’s previous models including an improved cylinder, improved spacing mechanism, improved paper carriage, and adjustable paper guides. Many of these improvements were due to the inventiveness of Remington mechanist George B. Webb.
The first commercially successful typewriter was designed by Christopher Sholes and Carlos Glidden and manufactured by gunmakers E. Remington and Sons in 1874 in Ilion, New York. The typewriters manufactured by E. Remington and Sons had been sold by the company Wyckoff, Seamans & Benedict since 1882. In 1886 E. Remington and Sons sold the entirety of their typewriter interests to Wyckoff, Seamans & Benedict. Wyckoff, Seamans & Benedict manufactured their typewriters under the Remington Standard Typewriter Company name beginning in 1892. The company became the Remington Typewriter Company in 1902, before merging with the Rand Kardex Company in 1927 to become Remington Rand. The Remington Rand plaque on the typewriter would have been a later addition to the Standard No. 6. Remington Rand continued to sell typewriters until around 1955, when it was acquired by the Sperry Corporation.

The Blickensderfer typewriter No. 6 was manufactured by the Blickensderfer Manufacturing Company of Stamford, Connecticut from 1910 to around 1928. The Blickenderfer No. 6 was essentially the Blickensderfer No.
Description
The Blickensderfer typewriter No. 6 was manufactured by the Blickensderfer Manufacturing Company of Stamford, Connecticut from 1910 to around 1928. The Blickenderfer No. 6 was essentially the Blickensderfer No. 5 in an aluminum frame, and could be ordered with either a standard QWERTY keyboard or a DHIATENSOR keyboard. This model has the DHIATENSOR keyboard, which Blickensderfer called their “scientific” keyboard because the most used letters—“D, H, I, A, T, E, N, S, O, and R”—were on the bottom row nearest the space bar to minimize necessary hand movement. The aluminum frame of the No. 6 made it exceptionally portable, weighing only 5 pounds, and came in a leatherette case for easy carrying.

This Standard Number 2 typewriter was manufactured by E. Remington and Sons around 1878. The Standard No. 2 was one of the first commercially successful typewriters, refined from the original designs of Christopher Sholes and Carlos S.
Description
This Standard Number 2 typewriter was manufactured by E. Remington and Sons around 1878. The Standard No. 2 was one of the first commercially successful typewriters, refined from the original designs of Christopher Sholes and Carlos S. Glidden in the Sholes and Glidden typewriter. The Remington 2 was an upstriking machine—the carriage held the paper type-side down—and the keys would rise up and strike the paper through the ink ribbon from the bottom. This required typists to raise the carriage if they ever wanted to see what was written. The Remington 2 had a QWERTY keyboard, and its commercial success led to it being adopted as a standard, even as its design was primarily to prevent the type bars from jamming and not to increase typing speed or ease of use. This model has four keys that project from below the keyboard that operated to stop the carriage at proper positions for tabulating and billing.

This is a Smith & Corona Silent typewriter manufactured by around 1934. The model was made to be portable, and operate quietly thanks to the Smith Floating Shift used in the machine (note the cursive word “Floating” above the shift key).
Description
This is a Smith & Corona Silent typewriter manufactured by around 1934. The model was made to be portable, and operate quietly thanks to the Smith Floating Shift used in the machine (note the cursive word “Floating” above the shift key). When the shift key was invented, it originally shifted the cylinder, or platen, to be struck in a new position by the capital letters on a typebar. The floating shift moved the typebars up and down instead, allowing for a smoother typing action. The four row keyboard has a QWERTY layout.
The success of the Standard Typewriter Company’s Corona model typewriter prompted the company to change its named to the Corona Typewriting Company in 1914. In 1926 the company joined with the L. C.

This Vari-Typer electric typewriter was made by the Ralph C. Coxhead Corporation in New York, New York around the late 1937. The Vari-Typer was based on the body of a Hammond No. 2 typewriter, which had an unusual typing mechanism.
Description
This Vari-Typer electric typewriter was made by the Ralph C. Coxhead Corporation in New York, New York around the late 1937. The Vari-Typer was based on the body of a Hammond No. 2 typewriter, which had an unusual typing mechanism. Instead of the character striking the paper from the front of the machine, the printing is done by a hammer in the back of the machine striking a type-carrying shuttle in the front of the machine, with the paper and ink ribbon in between to receive the impression. The Vari-Typer was so named because it had the ability to print in a variety of typesets in various sizes, including math formulae, special symbols, and foreign characters with an easy replacement of the type shuttle. The Vari-Typer would make direct impressions of the character on the paper that could then be reproduced by a variety of processes including litho-plates, mimeo stencils or photo-offset printing. This Vari-Typer is an electric typewriter that would automatically rewind the carriage at the end of each line.
The type-shuttle and hammer typing mechanism present in the Vari-Typer evolved from the Hammond typewriter invented by James Bartlett Hammond in 1884. James Hammond founded the Hammond Typewriter Company to produce typewriters with his patented mechanism, which enjoyed success in the late 19th and early 20th century, winning the gold medal at the New Orleans Centennial Exposition. Much could be said about Hammond’s affairs towards the end of his life, but the story of the Vari-Typer merely depends on Hammond’s patents passing to the Frederick Hepburn Company, and then ending up in the hands of the Ralph Coxhead Corporation around 1929, the company that eventually produced this Vari-Typer.

Description
This is a Demountable typewriter that was manufactured by the Demountable Typewriter Company of Fond du Lac, Wisconsin during the 1920s. The Demountable was designed by DeWitt Clinton Harris who had previously brought the Harris Visible and the Rex Visible typewriters to market. The Demountable bears a strong resemblance to these previous typewriters, but as the name suggests, the Demountable can be separated into three main components without the use of any tools. The Demountable could be separated into the frame unit, carriage unit, and the action unit, allowing for the replacement of parts as the type bars or platen wore out as well as allowing the use of different carriage lengths without having to buy a totally new machine.

Williams received patent number 501753 on July 18, 1893 for his type-writing machine invention. Prior to William’s design, most typewriters were blind-writing upstriking machines, forcing the typist to lift the platen to see their work. Williams’s design allowed for visible writing with an intriguing “grasshopper” typing mechanism. The typebars were arranged in two semi-circles around the platen and rested on an inking pad. When their key was struck, the typebar rose up and sprung forward to hit the paper, printing a visible line.
