Blickensderfer No. 5 Typewriter - Historic Portable Typewriter Design #2315635 (License: Personal Use)

This detailed line drawing depicts the Blickensderfer No. 5, a groundbreaking portable typewriter introduced in 1893 by George C. Blickensderfer. Its defining feature was the removable type cylinder (or “type wheel”), allowing users to switch fonts or languages instantly-a major innovation over traditional typebars. The machine’s lightweight aluminum body and simplified keyboard (with only 28 keys using the DHIATENSOR layout) made it popular among journalists, travelers, and early office workers.
