CHARLES PHILIP HUNTINGTON of the firm of C. & J. G. Potter of Darwen in the
County of Lancaster, Paper Manufacturers and Paper Stainers IMPROVEMENTS
IN MACHINERY FOR PRINTING PAPER OR OTHER MATERIAL, SPECIALLY APPLICABLE
TO PRINTING PAPERHANGINGS
"
"
My invention has reference to machinery for printing paper or other material in
a number of colors at one process by means of a number of rollers each furnished
with color and set around a central cylinder around which the paper passes, receiving
the various imprints in its progress. These rollers in the machinery hitherto
employed for this purpose have been driven by a large toothed wheel rigidly fixed
to the shaft which carries the central cylinder.
Now according to my invention I mount the said wheel loosely on, the shaft and
obtain the power for driving it by friction from the central cylinder or from
another roller according to circumstances. As the large toothed wheel and its
dependant rollers are thus driven by friction from the paper as it is being printed,
greater accuracy is given to the imprints than when the rollers are driven by a
wheel which is rigidly fixed to the shaft carrying the cylinder.

In carrying out my invention I drive one roller (either plain or engraved) by..
friction upon the paper or material being printed, and 1 drive the large wheel and .
the other rollers by gearing from the first roller so that their progress exactly,
coincides with its own,

CHARLES PHILIP HUNTINGTON of the Firm of C. & J. G. Potter of Darwen in
the County of Lancaster Paper Manufacturers and Paper Stainers "IMPROVEMENTS
IN MACHINERY FOR PRINTING PAPER OR OTHER MATERIAL, SPECIALLY APPLICABLE
TO PRINTING PAPER HANGINGS
"
My invention has reference to machinery for printing paper or other material in
a number of colors at one process by means of a number of rollers each furnished
with color and set around a central cylinder around which the paper passes,
receiving the various imprints in its progress. These rollers in the-machinery
hitherto usually employed for this purpose have been driven by a large toothed
wheel rigidly fixed to the shaft which carries the central cylinder.
Now according to my invention I mount the said wheel loosely on the shaft and
obtain the power for driving it as hereinafter described with reference to the 1
annexed drawings in which Figure 1 is a side elevation of a printing machine
constructed, according to my invention and Figure 2 a part plan. Z is the central
cylinder to which rotary motion may be imparted in any ordinary manner by
means of the shaft on which it is rigidly fixed. The paper to be printed is supplied
in the usual way from a reel Y and is passed over rollers or rails to the cylinder Z
and thence between rollers D and E. From these rollers it is carried forward to
receive its various imprints by a blanket X which is stretched round the
cylinder Z and also passes between the rollers D and E. The roller D is a metal
-roller driven from the shaft of the cylinder Z and at the same speed by the toothed
gearing A, B, C, the wheel A being rigidly fixed on the cylinder shaft. The s
roller E may be driven by friction from the roller D or by friction direct from the
cylinder Z in which case the roller D) and intermediate gearing are dispensed with
but I find in practice that it is better to drive the roller E by gearing I J from the
roller D. G is the large toothed wheel which drives all printing rollers H H by
ordinary goaring; it is loose on the shaft of the cylinder Z and is driven by the
roller E by means of tho intermediate gearing K L. All the printing rollers H are
thus driven at exactly the same speed or rate of progress as the roller E and great
accuracy is thus given to the imprints.
The roller E, the use of which in combination with the loosely mounted wheel G
which it drives, constitutes an essential featuro of my invention may either be
plain, or engraved in which case it will constitute one of the printing rollers, or it
may be an oxpanding roller. If its size be increased or decreased the speed of the
paper is increased or decreased whilst the speed of the printing rollers remains the
samo; this allows of a second printing being fitted in or suited to the first, if the
pattern requires more than one printing.
The roller E is supported by steps R fitted in sliding brackets S fixed to the side
of the machine and regulated by means of screws T or levers U to give it the
required pressure against the paper and roller D or against the paper and
cylinder. Z.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim:-
1
The combination with the large toothed wheel (G) which drives the printing
rollers (H) and which is loose on its shaft, of a roller (E) for driving the said wheel,

page_text: this roller being itself driven either by friction from another roller (D) or from the
large cylinder (Z) or by gearing from such other roller substantially as and for the
purpose hereinbefore described.
In witness whereof I the said Charles Philip Huntington have hereunto set
my hand and seal this twenty eighth day of February One thousand eight
hundred and eighty four
