Lucien S. Crandall Typewriter Patent Model

Crandall, Lucien S. · 1881-12-20

Lucien Stephen Crandall of New York, New York received patent number 251,338 on December 20th, 1881 for this type-writing machine patent model design. Crandall described his invention as a “design to furnish a typewriting machine of simple and cheaper construction and with a greater range of type, combining upper and lower case letters, figures, and punctuation marks, and working them all with one set of keys merely.” The design had two interesting elements, the first being what Crandall called a “type-sleeve,” which allowed the printing of both lower-case and capital letters. The type-sleeve was covered with raised characters that wrapped around the sleeve arranged so that the most frequently used letters are in the center of the row requiring less shifting of the sleeve. The capital letters and numerals were not activated by a shift key, but rather a laterally-oscillating key-lever (the gold switch on the upper left of the model) that moved the type-sleeve. You would move the switch one way to activate the numerals and punctuation, and the other way to activate the capital letters. The keyboard for Crandall’s machine was arranged in a non-QWERTY fashion.
