Year: 1867

page_text: LETTERS PATENT to Frederick Andrew, of Harpurhey, near Manchester,
in the County of Lancaster, Dyer and Printer, and Ellis Whittaker, of
the same Place, Foreman, for the Invention of "IMPROVEMENTS IN PRINTING
PROVISIONAL SPECIFICATION left by the said Frederick Andrew and
Ellis Whittaker at the Office of the Commissioners of Patents, with their
Petition, on the 18th November 1867.
We, FREDERICK ANDREW, of Harpurhey, near Manchester, in the County
of Lancaster, Dyer and Printer, and ELLIS WHITTAKER, of the same Place,
Foreman, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN PRINTING ROLLERS USED FOR PRINTING COLORS ON HANKS OF YARNS OR
THREADS," to be as follows:-
This Invention relates to those printing machines in which there are two
rollers having longitudinal ribs of equal or different thicknesses, and consists
in so arranging the ribs that two colors can be printed on the hanks instead of
In these machines all the ribs of the two rollers have hitherto been of
equal heights, but we make them alternately of different heights and cause
the higher ribs of one roller to correspond with the lower ribs of the other
roller, so that by using two color boxes and two distributing rollers the higher
ribs of one roller can print one color on the hanks, and the higher ribs of the
other roller another colour.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Andrew and Ellis Whittaker in the Great
Seal Patent Office on the 12th May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
ANDREW, of Harpurhey, near Manchester, in the County of Lancaster, Dyer
and Printer, and ELLIS WHITTAKER, of the same Place, Foreman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Frederick Andrew and Ellis Whittaker, Her special license that we,
the said Frederick Andrew and Ellis Whittaker, our executors, administrators,
and assigns, or such others as we, the said Frederick Andrew and Ellis
Whittaker, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN PRINTING ROLLERS USED FOR PRINTING COLORS ON HANKS OF YARNS
OR THREADS," upon the condition (amongst others) that we, the said Frederick
Andrew and Ellis Whittaker, our executors or administrators, by an
instrument in writing under our, or their, or one of our or their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next.
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Frederick Andrew and Ellis Whittaker,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Figures on the
.ccompanying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say):-
:-
This Invention relates to those printing machines in which there are two
printing rollers having longitudinal ribs of equal or different thicknesses, and
consists in so arranging the ribs that two colors can be printed on the banks
instead of one. In these machines all the ribs of the two rollers have hitherto
Leen of equal heights, but in our improved rollers we make them of different

page_text: heights, and cause the higher ribs of one roller to correspond with the lower
ribs of the other roller, so that by using two color boxes and two color rollers
the higher ribs of one roller can print one color on the hanks, and the higher
ribs of the other roller another color.
On the accompanying Sheet of Drawings, Fig. 1 is a transverse section of
two of our improved printing rollers with their corresponding color boxes and
color rollers, and Fig. 2 a longitudinal elevation of one end of one of the
rollers.
a represents the color boxes; b, the color rollers; and c, the printing rollers,
the higher ribs being marked d, and the lower ribs e. As the rollers are
turned by gearing the higher ribs always correspond with the lower ones, and
as it is only the higher ribs that can take the colors from the color rollers two
colors can be printed by one pair of printing rollers. It is evident the ribs
on the rollers may be alternately of different heights for printing two colors
in alternate stripes, and also that the numbers and positions of the higher
ribs may be varied to an indefinite extent according to the pattern required to
be printed on the hanks, it being understood that the higher ribs on one
roller correspond with the lower ones on the other roller.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be understood
that we claim, the improvements in printing rollers used for printing colors on
hanks of yarns or threads, as herein described and illustrated in the accom-
panying Sheet of Drawings.
In witness whereof, I, the said Frederick Andrew, for and on behalf of
myself and the said Ellis Whittaker, have hereunto set my hand and
seal, this Eleventh day of May, in the year of our Lord One thousand
eight hundred and sixty-eight.
Signed, sealed, and delivered by the
within-named Frederick Andrew,
in the presence of
G. SEPTIMUS HUGHES,
Patent Agent,
Manchester.
