Portable typewriter of the type-wheel class, manufactured by the Blickensderfer Manufacturing Company, of Stamford, Massachusetts, U.S.A. This machine is the Blickensderfer Model 7 and is a development of the earlier Model 5. The designer of the typewriter was George C. Blickensderfer.


The mechanism of the Model 7 used a rotating typewheel with three rows of characters around its periphery. The typewheel was mounted in front of and above the platen. Pressing a key first rotated and shifted the type-wheel to bring the selected character in front of the printing point and then pressed the wheel down and forward against the paper and platen. Ink was applied via a roller against which the type-wheel brushed during its downstroke. The typewheel could be easily changed to accomodate different character sets.


The Model 7 was supplied with either a QWERTY 'Universal' keyboard or Blickensderfer's 'Scientific' keyboard. On the latter, the front row of keys comprised the letters DHIATENSOR which Blickensderfer claimed made up 70% of the letters used in English. This machine has a 'Scientific ' keyboard.
