The Martin Howard Typewriter Collection has a new treasure to show off: a Munson typewriter, with horizontal rods that control a hammer that strikes the page from behind:
Munson 1 (Thanks Martin!)
The Munson typewriter is a remarkable piece of engineering, with a complex and original mechanical design packed into a small frame. Its inner workings are largely exposed, so the machine comes to life with moving rods and levers when being used.
The Munson does not have type-bars but uses a horizontal type-cylinder (about the size of ones finger) that slides from side-to-side and rotates to have the correct character move into place. Then a hammer strikes the paper from behind, pushing the paper against the ribbon and type-cylinder. Type-cylinders with different fonts were available.
With two shift keys, uppercase and figures, only three rows of keys are required.
The Munson was introduced in 1890 and did quite well on the market; however, today it is hard to find. The Munson became the Chicago in 1898 when the enterprise was bought and the typewriters were manufactured by The Chicago Writing Machine Co.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
