Keystone Typewriter Company, Harrisburg, Pennsylvania, 1899 – serial no. 1239

Photograph of the Keystone 1 typewriter.

The beautiful keystone typewriter uses a rotating type wheel, shaped like a section of a wagon wheel. The characters are molded onto the outside surface of this wheel, which rotates into position with the depression of a key. Then a spring-driven hammer strikes from behind to push the paper and ribbon against the type wheel. As a result, the paper is preloaded into a cylindrical holder behind the platen and unrolls up and out when typing.

The type wheel could be easily changed for different font styles on the Keystone typewriter.

There are two shift keys on the left, giving three functions to each key, allowing for three not four rows of keys.

The Keystone was a comparatively low priced keyboard machine, selling for just $35.00.
