“_ANNE_, by the grace of God, &c., to all whom these presents shall
come, greeting: _WHEREAS_, our trusty and well-beloved subject, Henry
Mills, hath by his humble peticon represented vnto vs, that he has by
his greate study, paines, and expence, lately invented, and brought to
perfection “_An Artificial Machine_ or _Method_ for the _Impressing_ or
_Transcribing Letters Singly_ or _Progressively_ one after another as in
_Writing_, whereby all _Writing whatever_ may be _Engrossed_ in _Paper_
or _Parchment_ so _Neat_ and _Exact_ as not to be Distinguished from
_Print_, that the said _Machine_ or Method, may be of greate vse in
_Settlements_ and _Publick Recors_, the Impression being deeper and more
Lasting that any other _Writing_, and not to be erased, or
_Counterfeited_ without _Manifest Discovery_, and having therefore
humbly prayed vs to grant him our Royall Letters Patents, for the sole
vse of his said Invention for the term of fourteen yeares.”
“_Know Yee_, that wee,” etc.
The first American typewriter of which any record remains is that
described in the patent granted to W. A. Burt, July 23, 1829. It was
called a “Typographer.” It had a segment bearing the letters of the
alphabet and corresponding notches acting as an index. A superposed
lever, which could be worked up and down, and also moved laterally, was
provided with a series of type, arranged in a segmental curve, so that
any type could be brought into place on the subjacent paper by swinging
the lever over to and down into the proper notch in the index segment
below. A restored model of this is to be found in the U. S. Patent
Office.

The first organized typewriter in which separate key levers were
provided for each type is a French invention. It is to be found in the
French patent to M. Progin (Xavier), of Marseilles, No. 3,748, Sept. 6,
1833 (Brevets d’Invention, Vol. 37, 1st Series, pl. 36). It was called a
Typographic Machine, and is shown in the illustration (Fig. 135).
Upright key levers _s_ are arranged in a circle around a circular plate
_n_. They have hook-shaped handles at the upper end, and terminate
below in forks that are pivoted to the shanks of type hammers, to raise
and lower them. These hammers are inked from a pad, and at a central
point deliver a printing blow on the paper below. The paper is held
stationary, and the whole nest of levers was moved over the paper for
each letter printed. The circular index plate _n_ had marked on it
opposite the respective levers the letters and characters represented by
said levers. Besides printing letters, the device was to be used for
printing music, and for making stereotype plates.
