Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HAROLD
POTTER, of Manchester, in the County of Lancaster, Esquire, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent, under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of December, in the third year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Harold
Potter, Her especial licence that I, the said Harold Potter, my exors, adñiors,
or assigns, or such others as I, the said Harold Potter, my exors, adiñors, or
assigns, should at any time agree with, and no others, from time to time and at
all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN PRINTING
CALICO'S, MUSLINS, AND OTHER FABRICS;" in which said Letters Patent is con-
tained a proviso obliging me, the said Harold Potter, by an instrument in.
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be enrolled in Her said Majesty's High Court of.
Chancery within six calendar months next and immediately after the date.of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said.
Harold Potter, do hereby declare the nature of my said Invention to consist in
printing calicos, muslins, or paper for paper-hangings, by means of what is.

DESCRIPTION OF THE DRAWING.
Fig. 1 represents the section of my colour box and roller, together with the
sieve and cut roller. A is the colour box; B, the roller running in the colour
box; C, the endless sieve; and D, the cut roller, which gives the pattern to
the calico, muslin, or paper. Fig. 2 represents a plan of the colour box and
roller (A and B, Figure 1). The same or similar letters upon each Figure
refer to the same or similar parts; E, E, are grooves in the roller, which fit
upon and rest against corresponding shoulders or fitting partitions F, F, in the
colour box; these partitions F, F, are carried up so high in the colour box as
to prevent any of the colour passing over the top of the same, and they fit the
rollers at E, E, so accurately that very little if any colour can pass between.
them or between either of them and the roller at F, F. By this arrangement,
I can have one colour in the compartment marked G, and another colour in the
compartment marked II, whilst the roller B is in motion, as well as when at
rest. I is the doctor, for scraping off the surplus colours from the sieve C; and
between the top of each partition E, E, and resting against the lower portion of
the doctor, I place vertically pieces of wood K, K, which keep the colours
returning from the doctor separate and distinct, so that each colour runs into
its own proper compartment. The colours being now upon the sieve, are
carried up separately, but simultaneously, to the cut roller D. Sometimes I
use two or more short rollers in the colour box, all the rollers being fixed upon
one axle or spindle; and when I use rollers so arranged, I sometimes use as
may distinct colour boxes as I have rollers on the same axle.
I have now described my improvements, with reference to the annexed
Drawing, in such manner that persons engaged in similar branches of printing
may practise the Invention. And I hereby declare, that I claim as my Inven-
tion, the taking of two or more colours from the same surface sieve in the process
of surface printing upon calico, muslins, or paper. And I claim the printing of
patterns upon paper for paper-hangings by means of engraved or figured or cut

page_text: metallic rollers. I further claim any combination of the above two improvements,
videlicet, printing from metallic rollers and surface printing, as above described,
when the fabric printed upon is paper for paper-hangings. And such my In-
vention being to the best of my knowledge and belief entirely new, and never
before used within that part of Her said Majesty's United Kingdom of Great
Britain and Ireland called England, Her Dominion of Wales, or Town of
Berwick-upon-Tweed, and I do hereby declare this to be my Specification
of the same, and that I do verily believe this my said Specification doth comply
in all respects fully and without reserve or disguise with the proviso in the said
herein-before in part recited Letters Patent contained; wherefore I do hereby
claim to maintain exclusive right and title to my said improvements.
In witness whereof, I, the said Harold Potter, have hereunto set my hand
and seal, the Eighth day of June, in the year of our Lord One thousand
eight hundred and forty...
Signed, sealed, and delivered by the within-
named Harold Potter, in the presence of

HAROLD (L.S.) POTTER.

Statute made for that purpose.
