IMPROVEMENTS IN ORNA- MENTING ARTICLES MADE OF TIN PLATE AND OF OTHER BRIGHT METALS
Year: 1857

page_text: LETTERS PATENT to Thomas Lawley, of Wolverhampton, in the County
of Stafford, Japanner, for the Invention of "IMPROVEMENTS IN ORNA-
MENTING ARTICLES MADE OF TIN PLATE AND OF OTHER BRIGHT METALS."
Sealed the 6th October 1857, and dated the 6th August 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Lawley at the
Office of the Commissioners of Patents, with his Petition, on the
6th August 1857.
I, THOMAS LAWLEY, of Wolverhampton, in the County of Stafford, Japanner,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN ORNA-
MENTING ARTICLES MADE OF TIN PLATE AND OF OTHER BRIGHT METALS," to be
as follows:-
I put a stop upon those parts of the metal I wish to remain bright, whilst
the other parts are engraved. When this is properly set the surface un-
covered is ready for engraving. This engraving is effected by means of a fine
pumicestone or other hard substance used either dry or with a spirit. When
the parts I wish engraved are sufficiently cut, I remove the stop with pure
water.
The stop is composed of gum, sugar, and beer mixed with vermillion or
other suitable powder, or a stop composed of varnish or asphaltum mixed
with vermillion or other suitable powder may be used, in which case I apply
the engraving powder with water, and afterwards remove the stop with a
spirit.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
LAWLEY, of Wolverhampton, in the County of Stafford, Japanner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of Angust, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Lawley, Her special licence that I, the said Thomas Lawley,
my executors, administrators, and assigns, or such others as I, the said
Thomas Lawley, 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
"IMPROVEMENTS IN ORNAMENTING ARTICLES MADE OF TIN PLATE AND OF OTHER
BRIGHT METALS," upon the condition (amongst others) that I, the said Thomas
Lawley, my executors, or 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 Thomas Lawley, 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:-
I put a stop upon those parts of the metal I wish to remain bright whilst
the other parts are engraved. When this is properly set, the surface un-
covered is ready for engraving. This engraving is effected by means of a fine
pumicestone or other hard substance used either dry or with a spirit. When
the parts I wish engraved are sufficiently cut, I remove the stop with pure
water.
The stop is composed of gum, sugar, and beer mixed with vermillion or
other suitable powder, or a stop composed of varnish or asphaltum mixed
with vermillion or other suitable powder may be used, in which case I apply

page_text: the engraving powder with water, and afterwards remove the stop with a
spirit.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
On the surface of any article of tin plate or of other bright metal, the parts
of a device or design which I desire to remain bright I stop out by means
of any suitable composition which I paint over or apply according to the
intended device or design, leaving uncovered the parts of the surface which
are desired to present a ground or dead effect in the device or design. I
engrave or rub over the uncovered parts with a rough surface or material.
The stops or compositions which I use, and to which I make no claim, are
either soluble in water or in spirit.
When I use gum and sugar with coloring material or powder, such as
vermillion, I mix at the rate of four ounces of gum, eight ounces of sugar,
and some vermillion to give color, and with these materials a quantity of beer
sufficient to render them fluid is used. When such stop or composition has
been applied by a brush or other usual means, according to the device or
design, and become dry and hard, the uncovered parts are rubbed with dry
pumicestone or with a gritty substance and spirit. When complete, the stop
or composition is removed by water, or a composition or stop may be com-
posed of spirit varnish, and vermillion, or asphaltum and vermillion, or other
powder combined with spirit, in which case the grit or engraving material is
used with water, and after the grinding or engraving has been accomplished,
so as to produce the dead effects desired, the stop or composition is to be
removed by spirit. By these means varied ornamental effects of a mixed
bright and dead character, according to design, may be produced at com-
paratively small cost on articles made of tin plate and other bright metal.
In witness whereof, I, the said Thomas Lawley, have hereunto set my
hand and seal, this Fifth day of February, in the year of our Lord
One thousand eight hundred and fifty-eight.
Witness,
JNO. ALCOCK.
THOMAS LAWLEY. (L.S.)
