ATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, Lincoln's, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifth day of December, in the first year of Her reign,
did, for Herself, Her heirs and successor, give and grant unto me, the
said Moses Poole, Her especial license, full power, sole privilege and
authority, that I, the said Moses Poole, my exors, admors, and assigns, or
such others as I, the said Moses Poole, my exors, admors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, the Invention of "IMPROVEMENTS IN PRINTING," communicated
to me by a certain Foreigner residing abroad; in which said Letters Patent
is contained a proviso that I, the said Moses Poole, shall cause a particular
description of the nature of the said Invention, and in what manner the
same is to be performed, to be inrolled in Her said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole, do hereby declare the nature of the Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to
the Drawing annexed, and to the figures and letters marked thereon, that
is to say:-
The Invention, as communicated to me from abroad, consists in improve-.
ments in parts of the apparatus used in setting up forms of type in the
process of printing whereby that process will be facilitated. And in order
to give the best information, that the Invention may be fully understood and
readily carried into effect, I will describe the Drawing hereunto annexed, but
I would first remark, that in setting up a form of type there are many wedges
employed, which are usually of wood, though sometimes portions of wrought
iron are resorted to, which are for the purpose of affixing the type, and giving
such fixity to them that they may be printed from, the wedges of wood and of
wrought iron being of various sizes and without much attention having been
paid to uniformity of angle or structure, and not only from the nature of
material when wood is used for wedges, but also from the want of uniformity
of system of the wedges employed, the making or setting up of a form of type
required much time and care in order to get truth of setting up, which cannot
be obtained with the wedges now employed without much care and skill of the
person employed.
Now the object of the Invention secured by the present Letters Patent is,
to construct the wedges (employed for the affixing and setting up forms of
type) of cast iron rendered malleable by ordinary well-known means, such
wedges being made according to one uniform system, by which, on bringing
two wedges together, their outer sides will at all times offer parallel surfaces
whatever be the difference of sizes of such two wedges.
DESCRIPTION OF THE DRAWING.
a, a, a, a, a, a, a, represent seven wedges, tho surfaces of which they are
composed being the line b, b, which may be called the base line, and the
line c, c, which may be called the angular line; hence it will be seon that the
wedges are all composed of portions of metal, the sides of which are to the
same angle, consequently when the faces or lines c, c, of any two wedges a bo
brought together the lines or faces b, b, will at all times bo parallel, and this
will be the case to whatever extent tho surfaces c, c, are driven one on tho
other; and it is the making of such wedges of one uniform system, and
forming them of cast iron rendered malleable, which constitutes the Invention.

page_text: d is a longer wedge but formed of a similar angle to the shorter wedges a, a;
and a', a', a', are three wedges placed over the other wedges, but having
their faces or lines c, c, opposite each other.
From the foregoing description, aided by the Drawing, the Invention will
be readily understood; and it will be evident that by using a system of wedges
such as has been described, much facility will be obtained in setting up forms
of type. And it is also desirable further to remark that, in order to keep such
wedges as light as possible and yet retain sufficient strength, the same are
made more or less hollow, as is shewn by the sections.
I would in conclusion remark, that I do not confine myself to any particular
angle for the wedges, but care should be observed not to have the angle so
obtuse as readily to give way by the usage to which the forms of type will be
subjected; and further, whatever be the angle chosen, the whole of the
wedges should be portions which, coming together as above explained, would
cause the angles b, b, to offer parallel sides.
In witness whereof, I, the said Moses Poole, have hereunto set my
