The World Type Writer Company of Portland—incorporated in Maine Aug. 19, 1886—patented the World Typewriter two months later.
Mabel Loomis Todd used a World Typewriter when setting Emily Dickinson's poems in type for the first time.
Two models of this delightful machine were produced with small variations. The World 1 wrote capital letters only. The World 2 wrote capitals and small letters.
The machine worked as simple as the other index writers. The user would point at a letter with the swinging index pointer and then stamp the letter onto the paper, using the keys over the platen on the left. This brought down the printing hammer onto the semi-circular rubber type sheet that was attached to the top of the index. An ink pad kept the type constantly inked. [Link]
