Improvements in or relating to Machines for Printing Designs upon
Paper or other Material, Especially Applicable for the Decorating
of Earthenware, China, Glass, Tiles, Granite, and the like.
I, WILLIAM HALES TURNER of Chell Lodge Tunstall in the County of Stafford,
Earthenware Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention embraces a hollow heated printing cylinder upon which the color is
placed and against which the strip or band of paper or other material upon which the
design is to be printed is pressed.
The roll of the strip band or piece may if desired be damped by a sized friction
roller or other suitable means such as a steam heated box; the strip is carried round
or between one or more hollow heated rollers preferably of glass and then between
the printing cylinder and another roller which is covered by a "blanket" and presses
the paper against the printing roller. It then passes off and over another roller
which is driven at a slightly increased speed so as to put a dosired amount of strain
upon the paper. The whole of these rollers or only a portion may be driven by power
but usually I prefer to drive only a portion of them. The color is applied by means
of a plate preferably of copper heated as required upon which the color is placed and
if the plate be inclined slides down to the roller the plate serving to apply the color
to press it into or onto the cylinder and to scrape off the surplus. The rollers and
cylinders may be placed upon shafts in lengths as required; thus for a narrow border
strip an inch or two would be sufficient while the next set of rollers might be several
feet wide and there may be any convenient number of rollers upon one shaft.

Improvements in or relating to Machines for Printing Designs upon
Paper or other Material, Especially Applicable for the Decorating
of Earthenware, China, Glass, Tiles, Granite; and the like.
I, WILLIAM HALES TURNER of Chell Lodge, Tunstall, in the County of Stafford,
Earthenware Manufacturer, 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 embraces a hollow heated printing cylinder upon which the color is
placed and against which the strip or band of paper or other material upon which the
design is to bo printed is pressed, such strip or band of paper being pressed against
the heated cylinder by another roller around which passes a blanket of india-rubber
or the roller may be faced or covered on its periphery with india-rubber in which
case cold water is occasionally passed through the centre of the roll to prevent it
slipping.
The color is applied by means of a plate preferably of copper heated as required
upon which the color is placed and if the plate be inclined, slides down to the roller the
plate serving to apply the color to press it into or onto the cylinder and to scrape off
the surplus.
Fig. 1 of the accompanying drawings represents an end elevation of a machine
constructed according to my invention and figure 2 is a detail of the apparatus for
applying the color.
A is the framework having vertical guides A' between which are fitted the blocks B
carrying the ends of the roller-shafts CC. The blocks are adjustable as to height
and distance apart by means of screws D and D¹ the former being turned by means
of the lever head d and the latter by a worm wheel d³ gearing with a worm on the
shaft of the hand wheel d².
C is the printing cylinder which is heated by steam air or gas in the usual manner
and ( is a hollow cylinder covered by a blanket of india-rubber over which the strip
of paper E or other material passes and by means of which it is pressed against the
printing cylinder. The roller C³ may be cooled by passing cold water through
the interior thereof either continuously or as often as necessary so as to protect it
from injury by contact with the heated roller C³.
F are brackets for supporting the roll E¹ of paper or other material which is
stretched before being printed upon by passing around a roller G and after printing
is carried off by rollers G' G' which are driven slightly faster than the printing roller
so as to put a desirable amount of strain upon the paper. The printing roller C' is
driven by means of a worm H which gears with a worm wheel C on the shaft C of
the printing roller. The worm is mounted on a vertical shaft H' and is driven by
means of a pulley H at the bottom-of the-said shaft. The whole of the rollers shown
in the drawing may be positively driven but I prefer to drive only such as have been

page_text: so described. Jis a metal plate or doctor by means of which the color is applied.
This plate may be heated as required and is stiffened along the whole of its length by
being clamped between bars J and J³, bolts J³ and wing nuts J' being employed for
securing the bars and plate together. The plate is mounted on centres K which rest
in sliding blocks K¹ adjustable as regards their distance from the cylinder (* by means
of screws K. The plate J is caused to bear against the surface of the cylinder C
by means of weights L which being capable of sliding on the levers L' enable the
pressure of the plate against the cylinder to be adjusted with the greatest nicety.
The plate being inclined towards the cylinder any coloring matter placed thereon will
slide onto the cylinder and fill the sunken parts therein which form the design the
remainder of the color being kept back by the edge of the doctor.
In constructing machines for carrying out my invention the various rollers and
cylinders may be placed upon shafts in such lengths as may be required, thus for a
narrow border strip an inch or two will be sufficient whilst the next set of rollers
may be several feet wide and there may be any convenient number of rollers upon
one shaft.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I declare that what I claim is :-
1. In printing machinery such as described the combination with the heated
printing cylinder C² of an india-rubber roller or blanket substantially as described.
2. In printing machinery such as described cooling the roller ( by means of water
or other means to protect it from excessive heat substantially as described.
3. In printing machinery such as described the method of applying the color direct
to the printing cylinder by means of a plate or doctor J without the intervention of
a roller substantially as described.
4. In printing machinery such as described the combination with the doctor J of
an adjustable balance weight or weights L for regulating the pressure of the doctor
against the cylinder substantially as described.
5. The complete method of and apparatus for printing on pottery tissue paper for
the purpose of "transferring” in the earthenware and ceramic trades substantially as
specified.
