Year: 1852

page_text: LETTERS PATENT to Léon Godefroy, Manufacturer, of Paris, in the
Republic of France, for the Invention of "IMPROVEMENTS IN
CAMPING A DIASTING DAZZING BAD DRINING WADDING"
PROVISIONAL SPECIFICATION left by the said Léon Godefroy
at the Office of the Commissioners of Patents, with his Petition,
on the 12th October 1852.
I, LÉON GODEFROY, Manufacturer, of Paris, in the French Republic,
do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN COVERING OR PACKING ROLLERS FOR PRINTING FABRICS" to be
as follows:-
My Invention consists of covering printing rollers with one or more
layers of a compound fabric composed of felt attached to calico or
woven fabric by means of india-rubber; this fabric is attached to the
metal roller by means of paste or glue, the metal having first been
coated with varnish. The fabric is caused to adhere closely to the
roller by being wound round with a band of calico until the cement is.
hard.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Léon Godefroy in the Great Seal Patent Office,
on the 12th April 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
LEON GODEFROY, Manufacturer, of Paris, in the Republic of France,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of October, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Iler reign, did, for Herself. Her heirs and successors, give
and grant unto me, the said Leon Godefroy. Her special licence that
I, the said Leon Godefroy, my executors, administrators, and assigns,
or such others as I, the said Leon Godefroy, my executors, adminis-
trators, 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 "IMPROVEMENTS IN
COVERING OR PACKING ROLLERS FOR PRINTING FABRICS," upon the condition
(amongst others) that I, the said Leon Godefroy, by an instrument
in writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, 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 I, the said Leon Godefroy, do hereby
declare the nature of the 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 (that is to say):
My Invention consists of covering printed rollers with one or
more layers of a compound fabric composed of felt attached to calico
or woven fabric by means of india-rubber; this fabric is attached
to the metal roller by means of paste or glue, the metal having
first been coated with varnish; the fabric is caused to adhere closely

page_text: to the roller by being wound round with a band of calico until the
ciment is hard. And in order that my Invention may be more fully
understood, and readily carried into effect, I will proceed to describe
the means pursued by me.
A piece of calico of the width of the roller to be covered, and suffi-
ciently long to go all round it, is to be coated with a layer of india-
rubber cement. It is then placed with its cemented face downwards on
a sheet of felt, the thickness of which will depend on the degree of
elasticity which it is desired to obtain; this layer of cement connects
the two fabrics, and forms a compound fabric suitable for covering
printed rollers according to my Invention; or when more elasticity
is required, two of these compound fabrics may be cemented together
with india-rubber cement or other compound of felt, and woven fabric
may be employed to form un waterproof and elastic covering for
printing rollers. I prefer that the printing rollers to be covered with
the fabric above described should be cast hollow, either in iron or
copper, with a central axis, the periphery being supported by means of
arms or spokes, and being further strengthened by means or ridges
or mouldings cast on the interior at intervals; the surface of the
roller to be covered is to be coated with copal varnish. to prevent the
oxidation of the metal. When this coat of varnish is quite dry it is
to be well rubbed all over with garlic. The compound fabric with which
the roller is to be covered is now coated on the felt side with paste or
gluc, and placed on the prepared roller; the garlic causes the paste
or glue to adhere to the varnish; the two ends of the fabric are now
strongly drawn together, and are cut straight with a knife and straight
edge, the whole is then wound round in a spiral direction with a band of
calico, and the roller is left in this state for 24 hours, when the external
band is removed and the roller is again left to dry.
Or in place of permanently attaching the elastic fabric above de-
scribed to the roller, it will frequently be found convenient to use it
(when printing fabrics) in the form of an endless band or travelling
apron passing round the printing roller to give the elasticity required.
I would remark that when using printing rollers thus covered it is
not necessary to employ nearly the same amount of pressure as is at

page_text: present required. I would also remark that I do not confine myself to
the exact details herein described. But what I claim is, the attaching
of an elastic and waterproof covering, such as is herein described, to the
pressure rollers used for printing fabrics. And I also claim the manu-
facture of the elastic fabric above described for covering and giving
clasticity to rollers for printing fabrics.
In witness whereof, 1, the said Leon Godefroy, have hereunto set
my hand and seal, this Seventh day of April, in the year of our
Lord One thousand eight hundred and fifty-three.
Taken and acknowledged by the within-
named Leon Godefroy, at Paris, on
this Seventh day of April 1858,
before me,
L. GODEFROY. (L.S.)
Her Britannic Majesty's Consul at Paris,
THOMAS PICKFORD. (L.S.)
