PART 155

In 1957, the Imperial Typewriter Company of Leicester in England
was finally able to perfect and thus demonstrate this “special design of a twin
keyboard typewriter
”. It was to be “used in the science field [so] reports can
be typed on the left keyboard and calculations are made on the right keyboard,
as it comes with additional symbols.”

The original concept was for a second (or indeed third) keyboard to
employ “different characters, such for example as mathematical or chemical
symbols or the characters of a foreign alphabet”. A “common carriage unit [would
be] bodily displaceable into operative association with any selected unit”.

Claude Wellington Robert Brumhill had first patented this design in
England in 1949, toward the end of his eight-year stint as lead design engineer
for Imperial in Leicester. It was the acme of his achievements for Imperial. He
had applied for a US patent for the double (and triple) keyboard in 1950 and
the patent was issued in 1954.

Brumhill had 10 patents for the Imperial Typewriter Company granted
in the US from 1942, one of them (for a ribbon guiding means) on this day (October 24) in 1945. In the latter part of his
career, Brumhill worked closely with Arthur Bott Pateman, who succeeded Brumhill as
Imperial lead design engineer in 1950. Pateman went on to become managing director
and then chairman of the Imperial Typewriter Company.

Three typewriters all in a row

Brumhill was born at St Neots in Huntingdonshire in 1892 and began
working as a mechanical engineer and tool maker at Imperial’s Leicester factory
in 1910. This was the year Imperial founder Hidalgo Moya  tracked down Swedish-born
mechanical engineer 
Eric Julius Pilblad (born Köping, April 12, 1880; died
1963), who was at that time working on a Canadian government contract with the
Sutherland Rifle Sight Company in New Glasgow, Nova Scotia. 
Pilblad, who had
immigrated to the US in October 1900, had apparently had considerable
experience working in the typewriter industry in America. In 1911 Pilblad began working alongside Moya in Leicester, and later with an
English engineer

, Arthur Tomlinson, before returning to the US in 1925. At that
point Tomlinson succeeded Pilblad as Imperial lead design engineer, to be
succeeded in turn by Brumhill in 1942.

After Moya‘s return to the US (around 1919), Pilblad and Tomlinson worked under William Arthur Evans (above) as Imperial board
chairman until 1933. Tomlinson, Brumhill and Pateman then all worked under Evans’
 son, Roger Martin Evans (below, 1907-1967), who was Imperial‘s works director and chief production engineer.

The Brumhill double keyboard invention was not entirely wasted and was referenced
a number of times, most notably in 1990 by none other than “The United States
of America
as represented by the Department of Health and Human Services”. This
was for – and catch your breath before reading on – an “Automatic orientation
of predefined chemical structures in conjunction with a computer terminal
employs respective protocols corresponding to a system state. The system states
can include a chain state, ring state, library state, and retrieve state. Upon
orientation, the object is attached according to a specified attachment command
to a parent graph. The protocols corresponding to connection of the object to
the parent includes rules regarding angles at which the structures can be
attached to one another, and another protocol governs rules respecting rotation
of the stored object through predetermined angles. Nodes of the object recalled
are automatically provided with markers in alphabetic order from the most
recently used marker corresponding to a letter of alphabet. Multiple alphabet
sequences are used. Specification of position is indicated by inputting the
lower case letter of the alphabet corresponding to the location desired. Bonds
can be specified between two markers.” And that’s just the title!

A double keyboard, I suppose, might be preferable to this, a situation demonstrated by American actress Barbara Hale in 1956:
