"
JOHN ALEXANDER LLOYD and ALFRED LLOYD, of Limehouse, in the County of
Middlesex. IMPROVED MEANS AND PROCESS FOR PRODUCING ORNAMENTAL AND
OTHER DESIGNS UPON SHEETS OF TIN PLATE AND OTHER METALS."
Our Invention has for its object improved means and process for producing designs
in two or more colours or shades upon the surface of sheets of tin plate or other
metal, which sheets having such designs so produced upon them are used for making
up into boxes, cans, canisters, dishes, trays, labels, or other articles, or may be used
in their flat state without being so made up.
We take the sheet of tin plate or other metal (either plain or coated with varnish
and dried), upon which the design is to be produced, and we coat its upper surface
with varnish or other sufficiently glutinous material, and of white or any desired
colour, by brushing such varnish upon it by hand, or by a revolving brush or
cylinder, or by means of a suitable press which presses the plate upon a surface
of stone, zinc, or other metal, or other material upon which the varnish has been
spread.
The design having been carefully prepared on paper or other material, and the
several colours or shades of which it is composed being shown or indicated thereon,
we prepare plates of thin metal, paper, or other sufficiently flexible and durable
material, as inany in number as the several colours of which the design is com-
posed, and through each such plate we cut or make perforations corresponding with
the particular colour in the design to which such particular plate refers.

page_text: The varnish or other glutinous material with which the plate is coated, as above
described, being still sufficiently adhesive or sticky, we place one of the perforated
plates upon its surface, adjusting it if necessary by marks made for such purpose,
and we dust or sprinkle the corresponding colour in a state of fine powder through
the openings upon the varnish. This we prefer to do by hand, by means of a soft
brush, pad, or dabber of cotton wool, cloth, or other suitable material, or by passing
the tin plate and perforated plate together under a roller of sufficiently soft material
covered with powder of the appropriate colour. We then remove the perforated
plate and the surplus powder, if any. Upon the tin plate we then place a second
perforated plate having openings or perforations corresponding with another of
the colours in the design, and we apply in the same way the corresponding colour
in powder.
As many perforated plates having been thus used in succession as are necessary
to complete the design, we place and adjust the tin plate in a lithographic or other
suitable press, by which border lines, or a background of black, brown, or other
desired colour is transferred to those parts of the design where it is required, from
the surface of a lithographic stone, zinc, or other metal plate, or other suitable
surface upon which the design has been prepared in the usual well understood
way; or the design may be entirely finished by means of the perforated plates
already described; the tin or other plate thus treated is then dried naturally or by
artificial means, and may be finally varnished and dried in the open air or in any
suitable oven.
Powdered colours may be employed of any kind suitable for the design or to the
character of the work which is being produced, and they may be applied by hand
with brushes as well as through perforated plates, and the coat of varnish or other
sufficiently glutinous material, which is first applied to the upper surface of the tin
or other plato, as above described, may be applied by means of a suitable press from
the surface of a stone, zinc, or other metal plate, or other suitable surface, parts of
the surface being left bright and uncoated, so as to form part of the finished design,
or a perforated plate, similar to those subsequently employed, may be used for such
purpose.
The openings or perforations in the several perforated plates described may be so
arranged that the openings, or part of the openings, through one such plate
correspond with the openings, or parts of the openings, through one or more of the
other such plates, and in this way two or more of the powdered colours may be
superposed and made to blend together, so as to form various combined or compound
tints.
Words, letters, figures, or other marks may be formed upon the surface of the tin
or other plate, as well as ornamental designs, as already described.
Where a final pattern of black, brown, or other desired colour is transferred to
the surface of the tin plate, as above described, we sometimes use for such purpose
a cylinder, upon the surface of which the design is formed in relief in wood, metal,
india-rubber, or other suitable material, the cylinder being made to revolve by hand
or other suitable power, the design upon its surface being coated with ink or piginent
from rollers in the ordinary well understood way, and the tin plate being passed
under it after being carefully adjusted, so that the design is produced precisely in
the position required.
Where the process as described is completed entirely by means of a sufficient
number of perforated plates, the tin or other plates may be inade into boxes, canis
ters, dishes, or other articles before the design is formed upon their surface, sufficiently
flexible perforated plates being used.
By our improved means and process, as above described, designs of great beauty
and attractiveness are produced upon the surface of metal plates more easily, cheaply,
and effectually than has heretofore been the case.

Our Invention has for its object improved means and process for producing designs
in two or more colours or shades upon the surface of shects of tin plate or other
metal, which sheets having such designs so produced upon them, are used for making
up into boxes, cans, canisters, dishes, trays, labels, or other articles, or may be used
in their flat state without being so made up.
In order to put our Invention in operation, we take the sheet of tin plate or other

means of a revolving brush or cylinder, or by means of a suitable press which
presses the surface of the plate upon a corresponding surface of stone, zinc, or other
metal, or other material upon which the varnish has first been spread.
We carefully prepare the desired design upon paper or other material, indicating.
or shewing upon it the several colours or shades of which it is to be composed, and
we then make thin plates of metal, paper, or other sufficiently durable and flexible
material, as many in number as the several colours or shades of which the design is
composed, and through cach such plate we cut or make openings or perforations
corresponding with the particular colour in the design to which such particular plate,
is intended to refer.

The varnish or other sufficiently glutinous material with which the plate to be
ornamented has been coated, as above described, being still sufficiently adhesive or
'sticky," we place one of the thin perforated plates upon its surface, adjusting it if
necessary to its proper position by register marks made for such purpose, and we.
then dust or sprinkle over it, and upon the varnish through the openings, a suffi-
cient quantity of the corresponding colour in a state of fine powder. We prefer to.
do this by hand, with the intervention of a soft brush, pad, or "dabber" of cotton
wool, cloth, or other suitable material, or it may be done by passing the tin or metal.
plate and the perforated plate together under a roller of sufficiently soft material.
covered or charged with a powder of the appropriate colour.
We do not confine ourselves to any particular kind of colour, which may be
mineral, vegetable, or animal, or a combination of two or more, to suit varying
circumstances and requirements.
The surplus powder, if any, having been removed from the surface of the tin
plate, we then take away the perforated plate, and upon the tin plate we placo and
adjust a second thin perforated plate, having openings or perforations corresponding
with another of the colours or shades in the design, and we apply in the same way
as that already described the corresponding colour in powder.
Having in this way used in succession as many thin perforated plates as are.
necessary to complete the design, we place the tin or other metal plate in a litho- .
graphic or other suitable press of any of the ordinary kinds (having first dried the
plate, if necessary, by means of natural or artificial heat), and we adjust it carefully.

the surface..of which the design has been prepared in any of the ordinary well:
understood ways, and inked with..black, brown, or other desired colour, the design.

tin plate round or between the coloured or shaded parts of the design, which have
already been produced by the above-described methods; or the design may be
entirely finished by means of the thin perforated plates used as above described.
· Instead of powder colours, moist colours may be applied through the openings in
the plates (which may be plain or varnished) by means of brushes or rollers. The
tin or other plate treated as described is then dried naturally or by artificial means,
and may be finally varnished and dried in the open air, or in any suitable oven or
stove.
The coat of varnish or other sufficiently glutinous material which is first applied
to the upper surface of the tin or other metal plate as above described, may be
transferred to the latter by means of a suitable press from the surface of a stone,
zinc, or other metal plate, or other suitable surface, upon which the varnish has first
been placed in the ordinary way, parts of such stone or other surface being left
without varnish, so that the corresponding parts of the finished design upon the tin
or other metal plate are left bright or uncoated, or a perforated plate similar to those
already described may be used for the purpose of applying the varnish to the plate,
and the powder colours may be applied by hand with brushes as required, as well as
through the perforated plates. .
We sometimes make the openings or perforations in the several perforated plates
described of such shape that the openings or parts of the openings through one such
plate correspond with or are in the same position as the openings or parts of the
openings through one or more of the other. such plates, and in this way two or more
of the powdered colours may be superposed and made to blend together, so as to
forin various combined or compound tints.
Words, letters, figures, or other marks or devices may be produced upon the surface
of the tin or other plate, as well as ornamental designs, as above described, and
where a final pattern, background, or border lines of black, brown, or other desired.
colour or shade is to be transferred to the surface of the tin or other metal plate, as
above described, we sometimes use for such purpose a cylinder, upon, the surface of
which the required.device is formed in relief in wood, metal, india-rubber, or other
suitable material, the cylinder being made to revolve by hand or other convenient
power. The design upon its surface having been coated with ink or pigment from
rollers or otherwise in the ordinary well understood way, the plate of tin or other
metal is passed under it after having been carefully adjusted, so that the design is
transferred from the roller exactly in the required position.
Sheets of tin plate or other metal ornamented by our improved means and process,
as above described, may be made up into boxes, cans, canisters, dishes, or other
articles; or where tlie designs are formed upon them entirely by means of a sufficient
number of thin perforated plates, they may be made up into such boxes, canisters,
or other articles before the designs are formed upon them, sufficiently flexible per-
forated plates being afterwards used to produce the designs upon them in the way.
above described.
Photographs, engravings, or other pictures or ornaments may be cemented or
otherwise attached, so as to form part of the design, to the plates ornamented by our
improved process, as above described, either before or after such plates have been
made up into boxes or other articles.
Designs of great beauty and attractiveness are produced by our improved means
and process, as above described, upon the surface of metal plates more easily, cheaply,
and effectively than has heretofore been the case.
Having now described our Invention, and the manner in which it is to be per-
formed, we claim,
The method of producing designs of two or more colours or shades upon sheets of
tin. plate or other metal by means of adhesive material to which powder colours
are applied in succession, substantially as described. :

page_text: Also, the combination of such method of so producing designs upon sheets of tin
plate or other metal, with the production upon such designs of border lines, back-
grounds, and other devices, by means of a suitable press, substantially as described.
In witness whereof, I, the said John Alexander Lloyd, on behalf of myself
and Alfred Lloyd, have hereunto set my hand and seal, this Twenty-fourth
day of December, in the year of our Lord One thousand eight hundred and
seventy-eight.
