The Caligraph was the second American typewriter to come on the market, after the Sholes and Glidden / Remington. Like the Remington, the Caligraph is an understroke typebar typewriter; you must lift the carriage in order to see what you have just typed. The Caligraph #1 (1880) types only in capital letters, but subsequent models type in both upper and lower case. The Caligraph's lower-case keys are the white keys in the middle of the keyboard; upper-case black keys are on either side. Not an arrangement that lends itself to touch typing! There are two space bars, one on either side. The long extension in front of the keyboard is necessary to accomodate the typewriter's system of leverage.

A mechanical typewriter is a machine: everything is operated by finger power. The force of your fingers is what makes the ink appear on the page. That's why mechanical typewriters often produce rather erratic, uneven print quality—because it's hard to press keys with the same force all the time. When electric, semi-electric, and electronic typewriters became popular in the mid-20th century, they automated many of the things a typist previously had to do by hand.
Most electric typewriters do away with the system of levers and typehammers. In some models, the type is mounted on the surface of a rotating wheel called a golfball. Other models use a daisywheel, which looks like a small flower, with the type radiating out from the end like petals. The keys on the keyboard are effectively electrical switches that make the golfball or daisywheel rotate to the right position and then press the ribbon against the page. Because the type is hammered under electrical control, every letter hits the page with equal force—so a big advantage of electric typewriters is their much sharper, neater and more even print quality.
