Improvements in Machines for Printing Designs in Correct Register
on both Sides of Fabrics at one Operation.
I JOHN PLATT of the firm of Mather and Platt of Salford Iron Works Manchester
in the County of Lancaster Engineer do hereby declare the nature of said Invention
for IMPROVEMENTS IN MACHINES FOR PRINTING DESIGNS IN CORRECT REGISTER ON
BOTH SIDES OF FABRICS AT ONE OPERATION, to be as follows:-
This invention relates to the Invention for which Letters Patent No. 1627 A.D. 1886
were granted to Peter Brown Wilson and consists in certain improvements or
modifications in the construction and arrangement of the parts of the machine
described in the Specification to said Letters Patent.
In that Specification the Patentee stated that he preferred to place the two printing
bowls one above the other with two printing rollers directly between the two bowls
the axes of all four being in a straight line or thereabouts and in his Drawings he
illustrates such an arrangement.
Now I propose to place the printing bowls preferably one above and slightly to one
side of the other and preferably in contact with one another and I place the two
printing rollers in nearly the same horizontal plane and on opposite sides of the pair
of bowls.
The chief advantages obtained by this arrangement are that I am able to use large
box wheels for the purpose of gearing the printing rollers together and I am also able
to use full sized colour boxes and doctors whereas in Wilson's arrangement as above
described only small box wheels and doctor colour boxes can be employed.
Any convenient and suitable number of printing rollers may be employed as in
Wilson's arrangement.

I JOHN PLATT of the firm of Mather and Platt of Salford Iron Works Manchester
in the County of Lancaster Engineer 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 the Invention for which Letters Patent No. 1627 A.D. 1886
were granted to Peter Brown Wilson and consists in certain improvements or modi-
fications in the construction and arrangement of the parts of the machine described in
the Specification to said Letters Patent.
In that Specification the Patentee stated that he preferred to place the two printing
bowls one above the other with two printing rollers directly between the two bowls
the axes of all four being in a straight line or thereabouts and in his Drawings he
illustrates such an arrangement.
Now I propose to place the printing bowls preferably one above and slightly to one
side of the other and preferably in contact with one another and I place the two
printing rollers in nearly the same horizontal plane and on opposite sides of the pair
of bowls.
Any convenient and suitable number of printing rollers may be employed as in
Wilson's arrangement.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying three Sheets of Drawings reference
being had to the figures and letters marked thereon.
.
Figure 1 is a side sectional elevation illustrating my improvements as applied to a
two colour machine for printing designs in correct register on both sides of fabrics.
Fig. 2 is an outline view of the front of the machine and Fig. 3 an end view showing
the gearing. for driving the printing rollers.
a is the frame of the machine 6 the lower and 6 the upper printing bowl in this
case shown in contact with one another; ce two printing rollers for applying colours
on one side of the fabric as it passes over the bowl and d d the two rollers for
printing the reverse side of the fabric as it passes over the upper bowl ; each
printing roller is provided with a furnishing roller c c and d d respectively which
furnishing rollers carry colour from the colour boxes c² ² and d² d² which are of tlie
usual full size, to the printing rollers which are scraped by doctor blades e e.
The furnishing rollers colour boxes and doctors are all carried by nip plates f which
are fixed on blocks mounted and free to slide in brackets g and adjustable by means
of screws g. The upper bowl & may be moved to or from the bowl as required by
means of adjusting screws h one at each end of the bowl.
Each printing bowl is provided with a blanket and grey cloth the first blanket and
grey cloth pass round guide pulleys and respectively thence together over a guide
pulley where they join the piece or fabric to be printed which is guided into the

page_text: machine over a guide pulley 1 the three together passing partly round the bowl b
where the fabric is printed on one side by the rollers cc; the blanket and grey cloth
leave the bowl b and return round the guide pulley m at the bottom of the machine
while the fabric to be printed passes from the nip of the bowls bb partly round the
latter with the second blanket and second grey cloth which are guided over a pulley n
the fabric being printed on the reverse side by the rollers d d and passing out of the
machine over a guide pulley o with the second blanket and grey cloth.
The chief advantages obtained by this arrangement are that I am able to use large
box wheels for the purpose of gearing the printing rollers together and I am also able
to use full sized colour boxes and doctors whereas in Wilson's arrangement as above
described only small box wheels and doctor colour boxes can be employed.
P
The improved arrangement of gearing is illustrated by Figs. 2 and 3 and consists
of a driven spur wheel mounted on a short shaft pon which is mounted a star
wheel 9 which gears into two box wheels one on each printing roller d. On the
shaft is also fixed a spur wheel p² which gears into a spur wheel s¹ fixed on a second
short shafts on which is fixed a star wheel t which gears into two box wheels u u one
on each printing roller c c. The bowls' are caused to rotate by the frictional
contact of the printing rollers c c and d d pressing on the fabric passing over the
bowls with the grey cloths and blankets.
Although I have shown and described a printing machine with two pairs of printing
rollers it is obvious that a greater number might be employed in a machine suitably
constructed or that only a single pair of rollers could be used.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what 1
claim is-
In a machine for printing fabrics in correct register on both sides the combination
and arrangement of the bowls and printing rollers substantially as herein shown and
described whereby the position of one howl in respect to the other can be adjusted
and large box wheels and full sized colour boxes and doctors can be used as
specified.
