page_text: LETTERS PATENT to James Wood, of 30, Barbican, in the City of
London, Printer, for the Invention of "AN IMPROVED PROCESS FOR
LETTERING AND ORNAMENTING GLASS, WHICH THE INVENTOR TERMS HYALO-
TYPY."
Sealed the 3rd July 1855, and dated the 11th January 1855.
PROVISIONAL SPECIFICATION left by the said James Wood, at the
Office of the Commissioners of Patents, with his Petition, on the
11th January 1855.
I, JAMES WOOD, of 30, Barbican, in the City of London, Printer, do
hereby declare the nature of the said Invention for "AN IMPROVED PROCESS
FOR LETTERING AND ORNAMENTING GLASS, WHICH THE INVENTOR TERMS HYALOTYPY,"
to be as follows (that is to say):-
My Invention, which has for its object the production of ornamental letters,
with accompanying designs or devices, for attaching to glass surfaces, to display
upon boards containing announcements and inscriptions which it is desirable
to bring permanently before the public, as those upon the fronts of offices,
assembly rooms, or public. houses, or the walls of the apartments of the same,
or in other similar localities, is carried into effect as follows:-I cause the
desired letters and ornamental figures to be printed on paper, gold leaf, sheet
metal, or other suitable thin material, and I then cut out and attach the same
by suitable means to the back of the glass surface on which they are to appear,
and. I then cover the back of the glass, and of the pieces of paper or other-

page_text: wise forming the letters and figures, with a suitable opaque paint or varnish to
form the ground of the pattern; by which means I produce the desired letters
and figures at a much smaller expense than is required by the ordinary process
of painting upon glass. I claim the mode of producing ornamental letters and
accompanying designs or devices upon glass surfaces, in the manner and for
the purposes herein-before described and set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Wood in the Great Seal Patent Office on the
11th July 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WOOD, of 30, Barbican, in the City of London, Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of January, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Wood, Her special licence that I, the said James Wood, my
executors, administrators, and assigns, or such others as I, the said James
Wood, my executors, administrators, and assigns, should at any time agree
with, and no others; from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED PROCESS
FOR LETTERING AND ORNAMENTING GLASS, WHICH THE INVENTOR TERMS HYALOTYPY,"
upon the condition (amongst others) that I, the said James Wood, by an instru-
ment in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said James Wood, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
My Invention, which has for its object the production of ornamental letters
and accompanying designs or devices for attaching to glass surfaces, to display
upon show-boards, containing announcements or inscriptions which it is

page_text: desirable to bring permanently before the public, as those upon the fronts of
shops or offices, assembly rooms, railway stations, taverns, or other public
places of resort, or the walls of apartments, or in suitable localities in which
such devices or designs are or may be exhibited, is carried into effect as
follows (that is to say):-I first cause the desired letters and ornamental
figures or devices to be printed on paper, gold leaf, sheet metal, or other
suitable thin material. I then cut out and attach the same by suitable means
(as herein-after more fully described) to the back of the glass surface on which
they are to appear. I then coat over or cover the back of the said glass, and
of the letters and devices on paper, gold leaf, or otherwise as aforesaid, with a
suitable opaque paint or composition to form the ground of the pattern, having
previously sized the said surfaces so as to prevent the paint or opaque com-
position from spreading and interposing between the glass surfaces and the
ornamental letters and devices; by which means I am enabled to produce
the desired letters and figures upon glass surfaces at a much smaller expense
than is required by the ordinary process of painting and ornamenting glass.
But in order that these my said improvements may be more fully understood
and readily carried into effect, I will now proceed to describe them by the aid
of the accompanying Drawings, reference being had to the letters and figures
thereon marked (that is to say):-
Fig. 1 represents a front view of one of my improved show-boards; and
Fig. 2, a back view thereof, part of the frame of which is removed for the
purpose of showing the lettering and opaque coating upon the surface of
the glass. In each Fig. the same letters of reference denote similar corre-
sponding parts. A, A, frame of wood; B, B, glass plate fitting the frame in
the ordinary manner; C, C, ornamental letters cut out of the various materials,
and displayed and set forth as in manner shown; D, D, design or device;
E, E, opaque paint or composition, forming the ground of the pattern; F, F,
frame-board protecting back of design.
'In conclusion, to the foregoing description I would here briefly remark, that
for the convenience of printing the ornamental letters or figures in different
colors, the several designs, engravings, or otherwise, should be arranged for
printing on the paper, gold leaf, or other material, so as to leave but little
space or margin between them for the convenience of cutting out, which may
be done either by hand or any other suitable method; by these means entire
alphabets of any appropriate character or design may be advantageously.
printed in various colors, presenting, by change of tint and color, the appear-
ance of a new or varied design at little cost or labour.
In the employment of adhesive substances for attaching the different letters

page_text: or designs upon the glass, I prefer the use of gum arabac, or the white of
egg, with which I cause the face or printed surface of the letters, &c. to be
moistened, and then placed upon the back of the glass, so as to form the
pattern as represented when dry. I then, as in manner aforesaid, size the back
of the glass plate or surface, together with the letters and designs, for the
purpose of securing the endges of the said ornamental letters or designs,
and preventing the opaque paint or composition from spreading or running
underneath.
Having now fully described the nature of these my said improvements,
and the manner in which the same are to be, performed, I would have it
clearly understood that I do not by any means intend to confine myself to the
précise details herein-before described, as the same might be varied without
departing from the general principle of this my said Invention; but that
which I do claim as new and of my said Invention is, the mode of producing
ornamental letters and accompanying designs or devices upon glass'surfaces, in
the manner and for the purposes herein-before set forth and described.

thousand eight hundred and fifty-five.
