PALANTYPE MACHINE, 1960's

Palantype or Stenography machine, they are very similar. Stenography is American Palantype is British. The former has less keys than the latter, making certain words ambiguous as both machine use Phonetic sounds as a means of typing information, similar to shorthand, but typed instead. Palantype machines can differentiate certain words better because of the extra keys. In spite of this the Palantype was less favourable amongst users and fell out of favour. Words can be typed on these machines at over 200 words per minute. They can often be seen in movies containing courtroom Dramas as the spoken word could be recorded quickly.

DICTAPHONE RECORDING MACHINE, circa 1940

The name "Dictaphone" was trademarked by the Columbia Graphophone Company in 1907, which soon became the leading manufacturer of these machines. This continued the use of wax cylinders for voice recording. They had fallen out of favour for music recordings, in favour of disc technology. Dictaphone was spun off into a separate company in 1923 headed by C. King Woodbridge.

DICTAPHONE RECORDING MACHINE AND CYLINDER, 1940's

Dictaphone was an American company, that produced sound recording devices most commonly used to record speech for later playback, or to be typed into print. The name "Dictaphone" is a trademark, but in some places it has also become a common way to refer to all such devices.

The name "Dictaphone" was trademarked by the Columbia Graphophone Company in 1907, they soon became the leading manufacturer of such devices.

After relying on wax cylinder recording through to the end of World War II, in 1947 Dictaphone introduced their Dictabelt technology, which cut a mechanical groove into a plastic belt instead of into a wax cylinder. This was later replaced by magnetic tape recording and eventually hard-drive recording.

REMINGTON STANDARD No 7 TYPEWRITER, 1896

This machine has wooden keys and is poor condition but all the marks and transfers still remain. Its Serial Number is 159,878 so it is probably made in the early 1900's.

The type is struck on the paper from underneath so the typist cannot see what has been printed without raising the Carriage assembly. Later this method was abandoned, due to pressure of competition, and replaced by front typing where the result can be seen.

Remington was the first to make the under-typing model after purchasing the rights from the inventor Christopher Laythem Sholes in 1876. By 1882 the name Remington was a brand only, Wyckoff Seamans and Benedict were producing them and bought sole rights to make the machines 3 years later.

This machine is in working order.

SMITH PREMIER TYPEWRITER No 10, circa 1908

This was the only full-keyboard front strike typewriter ever built.

When the Smith brothers' typewriter business ceased the name was bought by Remington who continued to make Smith Premier machines, including the No. 10(SP10).

The new Smith Premier (Remington) factory was opened in 1908. The Smith Premier No.10 with the new visible typing method was produced at the factory in addition to older up strike type machines which were still in use. Production of the No. 10 continued until 1921.

The Remington Junior was also built here.

ROYAL No 10 TYPEWRITER, 1927

Production of the Royal No 10 started in 1914. It had glass windows on each side so you could view the workings; earlier models had two on each side, later types had only one.

The Royal company were so confident of the strength and reliability of these machines that they dropped them in a crate from air planes as a publicity stunt to prove that they would still function after such abuse.

UNDERWOOD TYPEWRITER No 5, 1930's

This model of office typewriter was in use for many years, and was still popular when computers replaced mechanical typewriters. This model has patents dating back to September 26 1899. The model number has not yet been identified; we think it's possibly a Number 5

The Underwood No.5 typewriter was first produced in 1901 by the Underwood Typewriter Company of New York. It was designed by a German-American, Franz X. Wagner, and was the first typewriter with a reliable 'front strike' mechanism which allowed the typist to see what was being typed. It was also faster than other designs of the time, operating effectively with a lighter touch, and had shift keys for caps and lower case letters, plus a tabulator key.

BURROUGHS STANDARD ELECTRIC TYPEWRITER of 1932

Burroughs produced more calculators than typewriters, this is their Electric carriage return machine that continued in production for many years but did not alter much in that time.

Its advantage was that the carriage assembly could return automatically, other than this it was just a standard typewriter.

IBM SELECTRIC 82 GOLF BALL TYPEWRITER, 1978

In 1865, Rev. Rasmus Malling-Hansen of Denmark invented the Hansen Writing Ball, which went into commercial production in 1870.

Instead of a 'basket" of pivoting type bars the Selectric had a pivoting type element (often called a "type ball") that could be changed so as to display different fonts in the same document, resurrecting a capacity that had been pioneered by the moderately successful Blickensderfer typewriter sixty years before.

One of the main advantages of the 'Ball' writers is removal of the problem of type bars becoming tangled due to by pushing two or three keys grouped together at the same time or by very fast typing, (particularly on poorly maintained machines), caused by working the machines faster than the bars could relax.

COMPTOMETER CALCULATOR, 1950's

The comptometer was invented by Dor Eugen Felt in the 1980's in America. Dorr E Felt started his first prototype during the Thanksgiving holidays of 1884. Because of his limited amount of money, he used a macaroni box for the outside box, and skewers, staples, and rubber bands for the mechanism inside. This prototype, called the macaroni box, is in the Smithsonian Institution in Washington, D.C. Units like the one shown were leased in large numbers by companies such as Sumloc Comptometer, who Purchased the rights in England in 1960, until electronic adding machines replaced them. See Item A1157. The machines worked by adding only and other functions were completed by progressive use of the keys.
Similar to the Sumlock machines leased by the bell Punch Company.
Not all Comptometers are of Bell Punch origin. Many were made and marketed by others, whether Bell Punch had there own manufacturing base for there machines is not clear. This model Model L.C. 912/SF/6069 of unknown manufacture could have been made in America and imported, then leased (as they usually were) by any number of companies.

This machine is Marked 'The London Computer Corporation'.

COMPTOMETER CALCULATOR 509/S, 1950's

This Model No 509/S/94.317 and models like this one were leased in large numbers by companies such as Sumloc Comptometer, until electronic adding machines replaced them. The machines worked by adding only and other functions were completed by progressive use of the keys, ladies often complained that the long strokes of pushing down the keys broke their finger nails. The curator of this museum used this model when she worked at Marks and Spencer in the 1960's and had the reputation of being the quickest operator in the office. The Plus and Sumlock are machines of the "Comptometer" type; the Sumlock being the full-keyboard version and the Plus the abbreviated-keyboard version. They are intended primarily for addition, but can also be used for subtraction, multiplication and division using learned techniques.
The main feature of this type of machine is that it has a full-keyboard and is "key driven", which means that pressing any key immediately adds the number on that key to the number displayed in that column, with carrying to the next column taking place where necessary.
The machine is designed so that keys in different columns can be pressed simultaneously. This means to add the cost of several identical items the operator arranges his or her fingers on the required keys and then depresses them all simultaneously the number of times for the number of items. Working in this way this type of machine is much faster than a 10-key type of machine where each digit has to be entered successively.
In 1960, the Bell Punch Company bought the British rights to the Comptometer design and trademark, and continued its development. In 1961, Sumlock, a division of the Bell Punch Company, was renamed The Sumlock Comptometer Ltd, and began marketing the first all-electronic desktop calculator, the ANITA Mark VII. The entire calculator division of the Bell Punch Company was bought by Rockwell International in 1973. Unfortunately they exited the calculator business in 1976 and shut down all operations.
Not all Comptometers are of Bell Punch origin. Many were made and marketed by others; whether Bell Punch had their own manufacturing base for these machines is not clear. See Item A1157.

SUMLOCK COMPTOMETER CALCULATOR MODEL 912/S , 1960's

In 1960 the Bell Punch Company gained the right to the name Comptometer from the U.S. Comptometer Corporation.
This is Sterling currency Comptometer, with 10 £ decades, shillings, and pence. Note that the pence column does not have keys 1 to 11, only the standard number of decimal keys (1 to 9) so to enter 10d or 11d the operator has to successively press two keys to give the required figure.
The keyboard.
From left to right there are 9 columns of keys for Pounds, 2 columns of keys to give up to 20 shillings, and one column of keys to give up to 12 pence (there are only keys 1 to 9 so to enter 11 pence, for example, you have to press e.g. 5 and then 6). The name Comptometer has become synonymous with this type of calculator by whoever made them. In 1957 the Felt and Tarrant Manufacturing Company changed its name to Comptometer Corporation and in 1960 Comptometer Corporation sold its UK operation, including the right to the Comptometer name in Britain, to Control Systems Ltd, the parent of Bell Punch, which merged it with its own company to form Sumlock-Comptometer. Comptometer Corporation then contracted with Control Systems to have all its machines made by Bell Punch in England and shipped back to the U.S.A. This resulted in all Comptometer production ceasing in Chicago in 1961, and in machines from Sumlock being marked with the Comptometer name. Although these machines were very successful and thousands were sold, only a few companies manufactured the "Comptometer" type of calculator. The main manufacturers were Felt & Tarrant (later Victor Comptometer) and Burroughs in the U.S.A., and Bell Punch in Britain.

The machine uses the same method as a disc-cutting lathe; the head is guided by a stylus running on the black disc in the centre of the turntable. The recording head runs over a flat magnetic disc for recording, this is made of the same material as ordinary recording tape. Date of manufacture could be as early as 1948. In spite of cheap tape recorders being available after the second World War, (Magnetic tape was invented by Germany during this period) EMI made these expensive machines to compete with Edison’s wax cylinder Dicta-phones which were popular world wide.

Believed to be one of the bells connected to the Transmitter No2
(see Item No A0226) positioned in the Houses of Parliament, the transmitter was activated when it was necessary to call the M.P's to the house when a vote was needed.
The bells would be in all the bars and meeting places that the M.P's were likely to be, if a vote was imminent then the members were obliged not to stray far from a bell, usually no more than a mile away.
The local MP did say these were still to be seen in the House of Commons.

POST OFFICE TRANSMITTER NO.2, 1900's

It has been said that this transmitter was used to ring the Division Bell in the Houses of Parliament and that one of the units was destroyed by a bomb during the Second World War; this however is unit No 2 and is alive and well. Only five units were made, so we believe.

When a plunger is pushed on the top of the unit the gears are turned thus winding up a weight hanging below. The weight starts to fall turning the mechanism. At the end of the gear line is an air type governor which controls the speed of fall; also connected is a rocker controlling two contacts which change alternately; these contacts are wired to terminals on the side of the unit

DICTOGRAPH OFFICE INTERCOM, 1950's

When offices started to use the Dictograph, the main drawback of the system was the need to install extensive wiring, and businesses were reluctant to change to such an expensive system to replace their tried and tested speaking tubes. Lamson Engineering was a major worldwide provider of office equipment at this time, and added Dictograph to their range of products. The suggestion may have come from Lamsons that Dictograph should rent their systems rather than sell them outright, and spread the buyer's cost over many years. By 1908 Dictograph systems rented from as little as five dollars and fifty cents a month for one master console and five stations. It was not an original idea. Companies in England such as General Electric had already launched into the rental market in the late 1890s , and the New System Private Telephone Company began in the late 1890s as well. Telephone Rentals began in 1902.

ADANA PRINTING PRESS, 1950's

Production of the range of Adana machines was between 1935 and the 1950's, and the 'Adana Agency' was founded in 1922 in Twickenham by Donald Affleck Aspinall Adana. All the machines were destined for the amateur market.

Up to 40 sheets can be printed on these machines in one minute by an inexperienced operator, once the type has been placed and put onto the machine.

Type is held in place by a box frame called a 'Chase' using blank spacers called 'Quoins' to pack out the complete area. When printing rollers move up onto a round disk covered in ink which revolves slightly on every press of the handle. Once the ink is on the 'form' (the completed 'Chase') the bed holding the paper ('Platen') to be printed is pressed hard onto the 'Form' and then removed after the handle returns to its rest position.

The 85 refers to the size of the flat bed on which the type set is placed - 8 x 5 inch. This machine was made after 1953 and cost £16.80.

Donated by Mrs Kathleen Williams, this printing press belonged to Kathleen's late husband, it was in constant use.
