page_text: LETTERS PATENT to Antoine Julien Deblon, of Fives-les-Lille, in the
Department of Le Nord, in the French Empire, Manufacturer,
for the Invention of "IMPROVEMENTS IN MACHINES FOR CALENDERING
STUFFS."
Sealed the 7th December 1869, and dated the 23rd June 1869.
PROVISIONAL SPECIFICATION left by the said Antoine Julicn Deblon
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd June 1869.
I, ANTOINE JULIEN DEBLON, of Fives-les-Lille, in the Department
of Le Nord, in the French Empire, Manufacturer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINES FOR
CALENDERING STUFFS," to be as follows:-
The object of the present Invention is to admit of regulating the
pressure required to be exercised on the different materials to be
calendered, this is effected by the combined action of three or more
cylinders (between which the stuffs are placed) actuated by a rotary
reciprocating motion.

page_text: The material to be operated on r, see the accompanying Drawings, is
wound on the wooden drum 8, this is arranged between three cylinders
a, a, a, the two lower ones a', a", have a backward and forward motion
communicated to them from the gearing i and shaft, which commands
the connecting rods p, p, p", of the respective cylinders; these rods are
articulated to the disc crank o. To facilitate and equalize the dis-
placement of the cylinders the rods p', p", are articulated at one point
of the disc o (thus forming an eccentric on the axis ) and the rod p
of the upper cylinder a, at a point of the disc o' turning on the same
axis as the rods p', ", the object of this double eccentric movement
is to displace the cylinder a equally with the cylinders a', a". The
toothed wheels j, j, and shaft j" communicate motion to the wheel i
and shaft. The upper cylinder a in addition to its backward and
forward motion is capable of being raised or lowered in its bearings for
the purpose of regulating the amount of pressure requisite for the
different materials, which is effected by the screws, the ends of which
are received by the nuts c. Motion is transmitted to the screws, and
thence to the pressing cylinder a, by means of the cog wheels d', d",
and pinion, which latter is common to both. Another screw e placed
to the left bears above it the wheel d", which, actuated by the pinion
communicates motion to the wheels '. Two bevel wheels g, g',
furnished with catch muffles lock alternately with an intermediate
muffle for transmitting a right to left movement to the wheel 9" for
raising or lowering the pressing cylinder a on the axis of this wheel;
the right pinion is fixed and the movable intermediate mulle is
worked by means of the lever », this latter mufle is actuated by the
cog wheel turning on the shaft . A driving pulley K sets the
screws d in motion and the crank and roller serve to slip the strap
on the said pulley either for turning or setting it free; is a cog
wheel fixed on the shaft which transmits motion to the bevel wheels
9, 9, 9. The governing pulley m and pinion mare borne on the
axis which turns the cog wheel i, by the intervention of which the
connecting rods p, p', p", are governed, and which latter communicate
the reciprocating motion to the cylinders a, a, a".

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTOINE
JULIEN DEBLON, of Fives-les-Lille, in the Department of Le Nord, in
the French Empire, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of June, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Antoine Julien Deblon, Her special licence
that I, the said Antoine Julien Deblon, my executors, administrators,
and assigns, or such others as I, the said Antoine Julien Deblon, my.
executors, administrators, and assigns, should at any time agrec 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 "In-
PROVEMENTS IN MACHINES FOR CALENDERING STUFFS," upon the condition
(amongst others) that I, the said Antoine Julien Deblon, my executors
or administrators, by an instrument in writing under my, or their, or ono
of their hands and seals, 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 Antoine Julien Deblon, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings, that is to
say:
The object of the present Invention is to admit of the regulation of
the pressure required to be exercised on the different materials to be
calendered, this is effected by the combined action of three or more
cylinders (between which the stuffs are placed) actuated by a rotary
reciprocating motion.

page_text: Fig. 1 is a lateral elevation of the machine; Fig. 2 is a front view;
Fig. 3 a plan, and Fig. 4, a side view opposed to that of Fig. 1.
The stuff or material to be calendered is wound on a wooden drum
and placed between the three operating cylinders a, a, a". The two
lower cylinders a', a", have an invariable position on their axes, but
like the upper one a they accomplish a rotary reciprocating movement
by aid of an eccentric or disc o keyed on the same axis as the toothed
wheel and which commands the connecting rods p, p', p", of the
respective cylinders a, a, a". In order that the cylinders are equally
displaced in their partial rotation the rods p', p", are articulated at a
point of the disc o and the rod p of the upper cylinder a at a point of
another disc o' turning on the axis constituting the connecting point
This double eccentricity given
of the rods p', ", on the eccentric o.
to the connecting point of the rod p on the disc o has for effect. to force
this rod to displace the cylinder a equally with those a', ", by their
rods p', p. The toothed wheels J, J', mounted on the same axis j"
serve to actuate the organs i and governing the rods p, p', p". The
upper cylinder a in addition to its backward and forward motion is
capable of being raised or lowered in its bearings for the purpose of
regulating the amount of pressure on the material. The degree of
pressure to be furnished to the cylinder a is determined by the screws it,
which pass through the nuts c, c, fixed to the frame of the machine.
The transmission of motion to the screws d, d, is effected by the toothed
wheels d, d', keyed to their ends, gearing with the common wheel e' of
the complementary screw e, which is actuated by the pinion which
turns right or left according as the pinion g, fixed at the lower extremity
of its axis, is in contact with one or other of the conical toothed wheels
h, ', (or bevil wheels) which for this purpose are supplied with a catch
mule which locks alternately with an intermediate one for trans-
mitting to the bevel wheel gear work g the right or left movement
which causes the screws d, d, to descend and consequently the pressing
cylinder d. The longitudinal or rectilinear working of the intermediate
mulle mis effected by the use of the locking lever », the mulle mis
gifted with the same rotary motion as the gear wheel K fixed on the
same axis K. A driving pulley 7 keyed to the axis q' of a pinion/
serves to move the pressing screws d, d, by aid of the wheel K and
pinions, h', and y, the crank and roller serve to slip the strap on
the pulley either for turning or setting it free. The reciprocating

page_text: 2
motion of the cylinders a, a', a", and the movement of the shafts
, p', p", is effected in the following manner:-On the axis q' of the
pulley and of the pinion is placed a pulley loose on this axis and
not participating in its movement, but is of one piece with a pinion *
which gears with the wheel J, the latter with the pinion J' and toothed
wheel i actuates the eccentric o, as already explained. Thus the
pulley 9 aud the pinion are for raising or lowering the cylinder « or
for producing pressure, and the pulley and pinion s serve to govern
the organs communicating the rotary reciprocating motion to the
cylinders a, a, a". Any arrangement of rack whether animated by
a rectilinear movement or not backward and forward, vertical, horizontal,
or otherwise may be employed in place of the shafts p, p',. p", and
actuated by pinions or segments keyed to the axes of the calendering
rollers a, a, a", and thus imparting thereto the requisite reciprocating
rotary motion for effectually calendering the materials.
Finally, what I consider as the characteristic features of my Invention
is the mode of calendering stuffs by the combined and simultaneous
action of three or more cylinders to which are imparted a rotary
reciprocating motion, with the facility of modifying according to desire
the capacity of the movement as well as the pressure by the displace-
ment of the cylinders, consequently what I claim and desire to secure
by Letters Patent is, the species of machine herein described and
illustrated by the accompanying Drawings in the manner and for the
purposes hercin set forth, reserving the right of varying or modifying
in form or dimensions the several parts mentioned, which may readily
be done without departing from the principle.
In witness whereof, I, the said Antoine Julien Deblon, have here-
unto set my hand and seal, this Twentieth day of December,
in the year of our Lord One thousand eight hundred and sixty-
niue.
JULIEN DEBLON. (L.S.)
