Improvements in or relating to Painting or Printing upon
Earthenware.
A communication from PAUL ARTHUR JOSEPH GASSE, Gentleman, of
32 Rue de la Révolution, Colombes (Seine Department), in the Republic
of France.
I ALFRED JULIUS BOULT, of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to multiple or polychrome printing. According to
present knowledge the imitation in machine painting of the effects of the brush
upon china, earthenware and the like, was obtained by two processes; first, by
etching the roll or plate in successive stages so as to obtain different effects of
light and shade, and second the effect of the brush was particularly obtained by
stippling the acid, or the wax or both the acid and the wax with a brush, fenther
or equivalent.
These effects were obtained simply by etching into the surface of the roller
or plate and producing the designs in intaglio or recessed into the roller or
plate, the colour being applied by what is known as a "doctor" or scraper which
would remove the colour from the whole of the surface of the roller excepting
the recessed portions which constitute the pattern. By the present invention I am
able to employ the before described process with an embossed roller and also to
extend the application to the employment of more than one roller, whether
embossed or not.
With the embossed roller the colour cannot be applied direct by a
"doctor" as
in the former case and I therefore apply it first to an indiarubber or equivalent
roller from which an embossed roller, preferably indiarubber, or indiarubber-
covered, takes the colour upon its embossed portions which correspond with the
embossed portions of the printing roller which will deliver the colour to the paper
from which it will subsequently be transferred to the china, or earthenware which
is to receive it. In addition to this however the effects obtainable from the
embossed roller may be improved by engraving or etching out of the embossed
portions or pattern, certain parts, to give the light effects.
To apply another colour a second printing roller is required with its complete
appliances of embossing roller, plain roller, and "doctor" for that particular
colour and the same for any other colour or colours which may be required, these
being all arranged in or in connection with the same machine or frame-work and
around the central roller or "bowl" which carries the paper upon which the
pattern is printed before it is applied to the biscuit ware. Aby convenient
arrangement may be employed in connection with this "bowl" or the paper for
lamping or sizing the latter, either from the interior of the "bowl" or otherwise
for what is known as "
wet printing."

1, ALFRED JULIUS BOULT formerly of 323 High Holborn but now of
111 Hatton Garden in the County of Middlesex, Chartered Patent Agent do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to multiple or polychrome printing. According to
present knowledge the imitation in inachine painting of the effects of the brush
upon china, earthenware and the like, was obtained by two processes; first by
etching the roll or plate in successive stages so as to obtain different effects of
light and shade, and second the effect of the brush was particularly obtained by
stippling the acid, or the wax or both the acid and the wax with a brush, feather
or equivalent.
These effects were obtained simply by etching into the surface of the roller
or plate and producing the designs in intaglio or recessed into the roller or plate,
the colour being applied by what is known as a "doctor"
or scraper which
would remove the colour from the whole of the surface of the roller excepting
the recessed portions which constitute the pattern. By the present invention I
am able to employ the before described process with an embossed roller and also
to extend the application to the employment of more than one roller whether
embossed or not.
The invention will be best understood by reference to the accompanying
drawings in which
Figs. 1 and 2 are two different elevations of a machine constructed according to
this invention.
With the embossed roller the colour cannot be applied direct by a "doctor" ns
in the former case and as shown in the drawings I therefore apply it first as by
means of a trough A to an indiarubber or equivalent roller 13 from which the
superfluous colour is removed by a doctor C and from which an embossed or
printing roller D preferably indiarubber, or indiarubber-covered, takes the colour
upon its embossed portions (which correspond with the embossed portions of the
printing roller) which will deliver the colour to the paper E froin which it will
subsequently be transferred to the china, or earthenware which is to receive it. In
addition to this however the effects obtainable from the embossed or printing
roller D may be improved by engraving or etching out of the embossed portions
or pattern, certain parts, to give the light effects.
for
To apply another colour a second embossed or printing roller D' is required
with its complete appliances of trough A', plain roller 13 and "doctor"
that particular colour and the same for any other colour or colours which may bo
required, these being all arranged in or in connection with the same machine or
frame-work and around the central roller or "bowl" which carries the paper E
upon which the pattern is printed before it is applied to the biscuit ware.
In the drawings the machine is shown as arranged for printing four different
colours, four different sets of embossed and plain rollers, troughs and doctors being
provided for this purpose, these being all marked with the same reference letters
with either no index numerals or different ones.
Any convenient arrangement may be employed in connection with this "bowl," F

page_text: or the
"bowl
paper for damping or sizing the latter, either from the interior of the
or otherwise as for instance by the roller G, trough H and doctor I for
what is known as "wet printing."
A machine constructed for printing a number of colours may be employed for
printing any number less than the full number by removing any of the plain
rollers B B &c. or any of the printing rollers D D' &c.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed I declare that what I claim is ;-
1. Painting or printing on paper for decorating earthenware china or the like
by means of a machine or apparatus comprising a roller or bowl such as F and one
or more sets of colour applying devices each having a plain or colour roller
"doctor" and u printing roller substantially as described.
2. In apparatus for use in connection with the painting or printing of earthen-
ware or the like the combination with a roller or "bowl" such as F of one or
more sets of colour applying devices each comprising a plain or colour roller a
"doctor" and a printing roller substantially as described and illustrated in the
accompanying drawings.
3. The combination and arrangement of parts constituting the complete machine
for use in connection with the printing or painting of earthenware or the like
substantially as described and illustrated in the accompanying drawings.
