page_text: LETTERS PATENT to Alexander Prince, of the Office for Patents, 4,
Trafalgar Square, Charing Cross, in the County of Middlesex, for the
Invention of IMPROVEMENTS IN ORNAMENTING AND ILLUMINATING SURFACES
Sealed the 21st June 1859, and dated the 22nd December 1858.
PROVISIONAL SPECIFICATION left by the said Alexander Prince at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
December 1858.
I, ALEXANDER PRINCE, of the Office for Patents, 4, Trafalgar Square,
5 Charing Cross, in the County of Middlesex, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN ORNAMENTING AND ILLUMINATING
SURFACES OF GLASS," to be as follows:-
This Invention relates to ornamenting and illuminating glass surfaces, and
consists in the application of lace or flower pattern glass having clear plain
centres or spaces, such centres or spaces being encircled or delineated by
ornamental, plain, or coloured bordering, so as to form an internal frame

page_text: pattern; and in and upon such clear centres or spaces chronio-lithograph or
other impressions, prints, or paintings are transferred, attached, or painted,
and then coated and covered with suitable crystal cements and varnishes as a
protection against damage from atmospheric influence or moisture.
The lace or flower patterns and ornamental bordering may be produced by
any of the known means, and may be matted or tinted, or partly plain and
partly tinted (or plain ground glass may be used), but always having open
clear centres or spaces with internal bordering.
The feature of this Invention being the production of ornamental or illu-
minated glass by using glass ornamented with lace or flower patterns over the
whole surface of the sheet (or ground glass may be used), but always having
clear plain centres or spaces ornamented with internal bordering or framework,
such clear centres or spaces being then illuminated or decorated with colored
or other impressions, prints, or paintings, as above described; this combination
producing ornamental or illuminated glass suitable for windows, blinds, screens,
lamp shades, and other useful and decorative purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Prince in the Great Seal Patent Office on the
22nd June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
PRINCE, of the Office for Patents, 4, Trafalgar Square, Charing Cross, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alexander Prince, Her special licence that I, the said Alexander
Prince, my executors, administrators, and assigns, or such others as I, the
said Alexander Prince, 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 "Iм-
PROVEMENTS IN ORNAMENTING AND ILLUMINATING SURFACES OF GLASS," upon the
condition (amongst others) that I, the said Alexander Prince, my executors or

page_text: administrators, by an instrument in writing under my, or their, or one of
their hands and seals, 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 Alexander Prince, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention relates to ornamenting and illuminating glass surfaces, and
consists in the application of lace or flower-pattern glass, having clear plain
centres or spaces, such centres or spaces being encircled or delineated by
ornamental, plain, or colored bordering, so as to form an interval frame pattern,
and in and upon such clear centres or spaces chromo-lithograph or other
impressions, prints, or paintings are transferred, attached, or painted, and then
coated and covered with suitable crystal cements and varnishes as a protection
against damage from atmospheric influence or moisture.
The lace or flower patterns and ornamental bordering may be produced by
any of the known means, and may be. matted or tinted, or partly plain and
partly tinted (or plain ground glass may be used), but always having open
clear centres or spaces with internal bordering.
The feature of this Invention being the production of ornamental or illu-
minated glass by using glass ornamented with lace or flower patterns over the
whole surface of the sheet (or ground glass may be used), but always having
clear plain centres or spaces ornamented with internal bordering or framework,
such clear centres or spaces being then illuminated or decorated with colored
or other impressions, prints, or paintings, as above described; this combination
producing ornamental or illuminated glass suitable for windows, blinds, screens,
lamp shades, and other useful and decorative purposes.
Having now fully described and set forth the nature and object of my said
Juvention in " Improvements in Ornamenting and Illuminating Surfaces of
Glass," together with the best means I am acquainted with for carrying the
same into practical effect, I would remark in conclusion that what I claim as my
Invention is, the production of ornamental or illuminated glass by using glass
ornamented with lace, flower, or other pattern, over the whole surface of the sheet
(or ground glass may be used), but always having clear plain centres or spaces
ornamented with internal bordering or framework, such clear centres or spaces

page_text: being then illuminated or decorated with colored or other impressions, prints,
.or paintings, in the manner herein described and set forth.
In witness whereof, I, the said Alexander Prince, have hereunto set my
hand and seal, this Twenty-second day of June, in the year of our Lord
One thousand eight hundred and fifty-nine.
ALEX. PRINCE. (L.S.)
Witness,
L. J. WETHERELL,
