It evidently took a mind not bound or hampered by the standard and
accepted way of operating synchronous systems to discard such old ideas
and to set forth boldly on a new pattern which, in reality, differed but
slightly from the then-established synchronous systems, and to sow the
seed for starting further developments leading to the present telegraph
typewriter, TWX, and TELEX intercommunicating systems. Such a man was
Howard L. Krum, who, in further thinking on the subject, came upon the
almost simple idea of having the transmitter start the receiver rather
than having them both start at the same time. This arrangement required
higher speed operation of the receiver and therefore the receiving code
pulse positions were spread over a shorter area, which meant
progressively decreasing the angular division of the receiving members.
Then, to set the received start pulse in the most favorable position
with relation to the following code signal reception, an orientation
adjustment of the receiver start position was provided.
(Note: On June 20, 1961, Kleinschmidt wrote to Howard Krum—then in
retirement in California—giving a short description of the Morkrum
Company activities, including the wording of the above last two
paragraphs, and asking him to write the Morkrum story. Howard Krum
replied on July 3, 1961, indicating his approval and saying that he
would be glad to put together some notes for Kleinschmidt. It was quite
a shock, therefore, when a letter was received from Howard Krum’s son,
Charles, in September of 1961, telling of his father’s sudden serious
illness. Then, regretfully, it was not long afterwards that word was
received of Howard Krum’s death on November 13, 1961.)

Howard Krum’s improved method for operating start-stop, permutation-code
telegraph systems was first applied to the Morkrum Green Code apparatus
to control the selecting and printing operations of the Blickensdoerfer
typewheel typewriter.
At this time the Kleinschmidt company and other manufacturers were
starting to produce permutation-code, start-stop telegraph printers
using typebar printing like the more modern typewriters which began
rapidly to replace the Blickensdoerfer, the Hammond, and the other
typewheel printing typewriters. Observing this situation, the Morkrum
Company started intensive development work to produce the No. 12 typebar
page printer, using the typebars and operating mechanism of the L. C.
Smith typewriter and platen of a Woodstock typewriter (fig. 8).
