Year: 1858

page_text: LETTERS PATENT to Charles Doley, of Birmingham, in the County of
Warwick, Manufacturer, and Edwin Bigland, of Smethwick, in the
County of Stafford, Designer and Glass Painter, and Thomas Henry
Worrall, of Smethwick, aforesaid, Lithographer, for the Invention of
"
Sealed the 11th January 1859, and dated the 20th July 1858.
PROVISIONAL SPECIFICATION left by the said Charles Doley, Edwin
Bigland, and Thomas Henry Worrall at the Office of the Commissioners
of Patents, with their Petition, on the 20th July 1858.
We, CHARLES DOLEY, of Birmingham, in the County of Warwick, Manu-
facturer, and EDWIN BIGLAND, of Smethwick, in the County of Stafford,
Designer and Glass Painter, and THOMAS HENRY WORRALL, of Smethwick
aforesaid, Lithographer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN ORNAMENTING METALLIC AND NON-METALLIC SURFACES," to
be as follows:
We carry our Invention into effect by first drawing the patterns upon glass
with a composition of bee's-wax, tallow, and pitch, and then etch them in
with fluoric acid; we next scrape off the composition and embed the glass
with plaster of Paris on to a slate or stone slab. We then fill up the part
etched with a composition of the following ingredients:-Bee's-wax, shellac,
tar, varnish, and gas black. We then take an impression upon unsized paper,
damp it, and place it upon the article intended to have the pattern upon it

page_text: and we rub the printed impression down with an india-rubber roller, then
wash off the paper with soap and warm water. We next put the article into
a cistern or tank filled with dilute nitric acid or other suitable acid. We
submit the said article to the action of the acid for a short time, then take it
out, and then well wash with strong ley made of potash, lime, soap, and
water, which removes all the composition, and the article will appear with the
pattern sunk into the body of the metal. For some kinds of work we prefer
the following method:-We take a thin sheet of metal and coat it over with
a composition of wax, tallow, and pitch, and draw a pattern upon it, we then
cut or bite the pattern with acid. We then coat over the article intended to
have the pattern produced upon it with either of the compositions described,
then wash over with whiting and water. We place the sheet of metal upon
the coated side, and brush with oil through the part cut out, which brushing
removes that part of the composition which is not wanted, then wash well
with soap and water, and submit it to the acid cistern or tank as before
described. We use the glass plates made as described, by etching, for the
purpose of embossing leather and other soft materials and metals, so as to
produce raised ornaments thereon.
The designs etched upon glass according to our Invention are sometimes
of the kind called positive and sometimes of the kind called negative. The
printing of designs from glass plates according to our Invention is applicable
to the ornamenting and embossing of metals and for printing in vitrifiable
or other colors, or with leaf metals or bronzes, upon glass, stone, ivory, bone,
wood, china, earthenware, papier mache, and other surfaces, and embossing
leather and other non-metallic surfaces for various purposes.
SPECIFICATION iu pursuance of the conditions of the Letters Patent, filed
by the said Charles Doley, Edwin Bigland, and Thomas Worrall in the
Great Seal Patent Office on the 12th January 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
DOLEY, of Birmingham, in the County of Warwick, Manufacturer, and
EDWIN BIGLAND, of Smethwick, in the County of Stafford, Designer and
Glass Painter, and THOMAS WORRALL, of Smethwick aforesaid, Lithographer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her reign,

page_text: did, for Herself, Her heirs and successors, give and grant unto us, the said
Charles Doley, Edwin Bigland, and Thomas Worrall, Her special licence
that we, the said Charles Doley, Edwin Bigland, and Thomas Worrall, our
executors, administrators, and assigns, or such others as we, the said Charles
Doley, Edwin Bigland, and Thomas Worrall, our 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 "IMPROVEMENTS IN ORNAMENTING METALLIC AND NON-METALLIC
SURFACES," upon the condition (amongst others) that we, the said Charles
Doley, Edwin Bigland, and Thomas Worrall, our executors or administrators,.
by an instrument in writing under our or their hands and seals, or under the
hand and seal of one of us or them, 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 we, the said Charles Doley and Edwin Bigland,
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:-
We carry our Invention into effect by first drawing the patterns upon glass
with a composition of bee's-wax, tallow, and pitch, and then etch them in with
fluoric acid. We next scrape off the composition, and embed the glass with
plaster of Paris on to a slate or stone slab. We then fill up the part etched
with a composition of the following ingredients:-Bee's-wax, shellac, tar,
varnish, and gas black. We then take an impression upon paper, damp it,
place it upon the article intended to have the pattern upon it, and we rub the
printed impression down with an india-rubber roller, then wash off the paper
with soap and warm water. We next put the article into a cistern or tank
filled with dilute nitric acid or other suitable acid. We submit the said
article to the action of the acid for a short time, then take it out and well
wash with strong ley made of potash, lime, soap, and water, which removes
all the composition, and the article will appear with the pattern sunk into the
body of the article. For some kinds of work we prefer the following
method: We take a thin sheet of metal and coat it over with a composition
of wax, tallow, and pitch, and draw a pattern upon it, we then cut or bite
the pattern with acid. We then coat over the article intended to have the

page_text: pattern produced upon it with either of the compositions described, then wash
over with whiting and water. We place the sheet of metal upon the coated
side, and brush with oil through, the part cut out, which brushing removes
that part of the composition which is. not wanted, then wash well with soap
and water, and submit it to the acid cistern or tank as before described. We
use the glass plates made as described by etching, for the purpose of embossing
leather, and other soft materials, so as to produce raised ornaments thereon.
The designs etched upon glass according to our Invention are sometimes of
the kind called positive, and sometimes of the kind called negative. The
printing of designs from glass plates according to our Invention is applicable
to the ornamenting of metals and glass, and for printing in vitrifiable colours
for burning on glass or other colors, or with leaf metals or bronzes upon
glass, stone, ivory, bone, wood, china, earthenware, papiér mâché, and other
surfaces.
Having now described the nature of our said Invention, and the manner of
carrying, the same into effect, we wish it to be understood that we do not limit
ourselves to the precise details herein described, as the same may be varied
without departing from the nature of our Invention; but we claim as our
Invention, the improvements in ornamenting metallic and non-metallic
surfaces herein-before described, that is to say, ornamenting the said surfaces
by means of designs etched upon glass plates, or by means of transfers obtained
by printing from the said etched glass plates.
In witness whereof, we, the said Charles Doley and Edwin Bigland,
have hereunto set our hands and seals, this Eleventh day of
January, in the year of our Lord One thousand eight hundred and
fifty-nine.
