TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jonn
CARR, of North Shields, in the County of Northumberland, Earthenware
Manufacturer, and AARON RYLES, of the same place, Agent, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of November, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto us, the said John
Carr and Aaron Ryles, Her especial licence, that we, the said John Carr and
Aaron Ryles, our executors, administrators, and assigns, or such others as
we, the said John Carr and Aaron Ryles, our executors, administrators, 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 law.
fully might make, use, exercise, and vend, within that part of the United
Kingdom of Great Britain and Ireland called England, the Dominion of
Wales, and Town of Berwick-upon-Tweed, our Invention of "AN IMPROVED
MODE OF OPERATING IN CERTAIN PROCESSES FOR ORNAMENTING GLASS;" in which
said Letters Patent is contained a proviso obliging us, the said John Carr
and Aaron Ryles, or one of us, by an instrument in writing under our or
one of our hands and seals, particularly to describe and ascertain the nature
of our said Invention, and in what manner the same is to be performed,
and to cause the same to be enrolled in Her said Majesty's High Court of
:I

page_text: 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.
NOW KNOW YE, that in compliance with the said proviso, we, the said
John Carr and Aaron Ryles, do hereby declare the nature of our said Inven-
tion to consist in the application to glass of the process usually called by
glass-stainers printing, with materials which have not heretofore been used
in that way, and under circumstances which give great facility for and make
great improvements in ornamenting glass. And in further compliance with
the said proviso we, the said John Carr and Aaron Ryles, do hereby describe
the manner in which our said Invention is to be performed, by the following
statement thereof, that is to say:-
First, as regards the process of staining glass, our improved mode of operat-
ing is as follows:-Instead of mixing the staining materials now used for that
operation, when levigated finely and dried with oil of turpentine or other
volatile oils, or water as usual, we mix them with boiled linseed or other
oil, such as is now used to mix with enamel colors when printed on glass;
and instead of floating the staining materials over the glass in a liquid state
as now practised, we print them on or transfer them as impressions from
metal plates, in the manner as now adopted in the operation of printing
enamels colors, and proceed, after the material transferred has been well dried,
to fire it for the color required in the usual way. When we operate with this
same staining materials, so mixed with oil as aforesaid, on what is called pot
metal, or on pieces of glass which are what is called flashed, opaque and
transparent shades are produced, leaving the surface of the glass quite smooth
and not raised in those parts, as in the common mode of applying body color
for the purpose of shading.
Secondly, as regards the operation of what is called stopping out. We also
mix the materials used for that purpose into a composition with boiled oil as
aforesaid, and transfer printed impressions on to the glass with it as before
explained, covering such parts as are not to be acted upon, and can then
float over the whole surface, including the parts so stopt out with liquid-
staining composition, and fire it as usual to produce the stain, after which,
the glass being cleaned, the pattern so printed on it in stopping out materials
is exhibited in the original color of the glass, and quite distinct from the
stained ground; or, a printed impression being transferred to the glass in
stopping-out materials as aforesaid, the remainder of the ground may be
òbscured, as it is called, in the usual manner, thus producing transparent
patterns on obscured grounds.
:

page_text: Thirdly, as regards the operation of what is called observing glass. We also
mix the materials which are used to produce this effect with boiled oil as
aforesaid, and transfer impressions from engraved metal plates on to the glass
as aforesaid, thus producing obscured patterns on transparent grounds.
Now, whereas it is evident that in all processes for ornamenting. glass by
staining, stopping out, or obscuring, the means we have discovered of mixing
the staining, the stopping out, and the obsuring materials with boiled linseed
oil, so as enable us to print with the composition from copper or other
engraved metal plates as aforesaid, gives us the power of greatly improving,
perfecting, diversifying, and multiplying the combinations of patterns, grounds,
and devices, while it does not deprive us of the aid of enamel colors to add
to that diversity as usual; and whereas we claim as our Invention in those
processes for ornamenting glass where staining, stopping out, or obscuring
materials are used,-
First, the transferring of the said materials in the form of impressions from
engraved plates of metal on to the glass, in the same manner as now prac-
tised in printing in enamel on glass, and which we are enabled to accomplish
by mixing the said materials with boiled linseed or other oil as aforesaid.
And secondly, the application of the staining material so mixed with oil as
aforesaid to pot metal, or to flashed glass generally, by which said improved
mode of operating with the said materials we are enabled greatly to improve,
perfect, render more exact, diversify, and multiply, the combinations of pat-
terns, grounds, and devices for ornamenting such glass as aforesaid, and to
produce the same so ornamented at a cheaper rate.
And such our Invention being, to the best of our knowledge and belief,
entirely new, and never before used within that part of Her said Majesty's
United Kingdom of Great Britain and Ireland called England, Her said
Dominion of Wales, or Town of Berwick-upon-Tweed, we do hereby declare
this to be our Specification of the same, and that we do verily believe this our
said Specification doth comply in all respects, fully and without reserve or
disguise, with the proviso in the said herein-before in part recited Letters
Patent contained; wherefore we do hereby claim to maintain exclusive right
and privilege to.our said Invention.
In witness whereof, we, the said John Carr and Aaron Ryles, have here-
unto set our hands and seals, the Ninth day of May, in the year of
our Lord One thousand eight hundred and forty-two.

(L.S.) CARR.
