Deblon, of Fives-lès-Lille,
Department of the Nord, France, Manufacturer, for the Invention
of "IMPROVEMENTS IN MACHINES FOR CALENDERING SMunna "
PROVISIONAL SPECIFICATION left by the said Antoine Julien Deblon
at the Office of the Commissioners of Patents, with his Petition, on
the 30th June 1871.
I, ANTOINE JULIEN DEBLON, of Fives-lès-Lille, Department of the
Nord, France, Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINES FOR CALENDERING STUFFS," to be
as follows:-
:-
The improvements referred to relate to calendering machines for
which I obtained Letters Patent under the No. 1918, and bearing date
the 23rd of June 1869, and in which three or more cylinders are
employed, between which the stuffs to be treated pass, these cylinders
being animated by a rotary reciprocating motion.

page_text: .
Fig. 1 of the accompanying Drawings is an end view of the machine;
Fig. 2 a front view; and Figs. 3 and 4 two plans.
The three cylinders a, a, a¹, between which the stuff to be calendered
is placed (see Fig. 5) are mounted on the axes b, b, b¹. The two lower
cylinders a, a, maintain an invariable position on their axes, but like
the upper cylinder a accomplish a rotary reciprocating motion in the
following manner:-On the lower horizontal axis c three pullics d, d², d",
are mounted. The pulley d" is like the centre one d¹ loose on its axis c,
whilst the other d is fixed to the same axis. With the pulley d" is a
cast-iron bevil pinion e governing the bevil wheel f, when the driving
band circulates on that pulley; but when the band is conducted to the
pulley d this latter turning the shaft c occasions the movement of the
second pinion e¹, which in turn governs the bevil wheelf, the axis of
which, moreover, supports a spur wheel g and pinion both loose on
the said axis; the pinion gears with a great wheel i loose on the axis b of
one of the lower cylinders. Behind the wheel i and connected with it
is a pinion which turns a wheel / keyed to the axis 6 of the lower
cylinder a On this same axis is also fixed a gear wheel which com-
mands the four toothed wheels m, n, g, and o, of the same diameter as
itself. The wheels m and g loose on their axes are the intermediaries
between the governing pinion 7; the two others n and o are fixed on the
axes b, b, of the upper and lower cylinders a, a'. This backward and
forward movement is indispensable to the rotary reciprocating motion of
the three cylinders a, a, a, and produces a complete calenderage of the
stuff placed between them. When it is considered that the stuff is
sufficiently calendered in one direction the movement is altered by
removing the strap or band of the pulley d" to that d. This displace-
ment occurs automatically by aid of a cleat or projection t connected to
the side of the wheel which never makes a complete turn. This cleat
in coming in contact with the fork t¹ causes the strap c to pass from ouc
pulley to the other. By the several positions it is capable of giving
this projection on the wheel the amplitude of the backward and
forward movement of the cylinders a, a, a, may be regulated, it is
evident, therefor, that should it be required that the cylinders should
always turn one way it suffices to raise the cleat t. Besides its
rotary reciprocating motion the upper cylinder may be raised or lowered
on its cushions, which enables the requisite pressure to be given to the
stuff.

page_text: The following is the manner in which ascension and descension of the
cushions p of the axis b¹is effected. Laterally with the machine two
loose pullies q, q², are arranged, on each of which a strap passes, which
imparts to them alternately by aid of a coupling screw (tendeur) an
opposite motion according as it is desired to raise or lower the cushions p.
On the same shaft as the pullies q, q', a bevil pinion is keyed gearing
with a wheel 8,, which. in. turn transmits motion to the spur wheel v by
means of the pinion w.. The axis x of the wheel v is screw cut to admit of
its. ascending; and descending, in a socket of the frame B of the machine.
The lower end of this axis receives. one of the cushions p of the
cylinder a¹.. The same arrangement of the spur-wheel and screw x is
established for displacing the other cushion, but with the concourse of a
wheel y intermediary between the two gear wheels v. This wheel y, by
reason of the displacement it submits to (since it must conform to the
up-and-down movement of the wheel v) has its boss or nave screw cut
to receive a screw of the same thread as the screws, but disposed in a
contrary direction. When the cushions p can be lowered no further, or
when the pressure on the stuff has attained its maximum, the strap slides
on the strap qor q' (according to which governs the descent) one or two
additional turns. may, if necessary; be given, when the stuff is as well
calendered as could be desired. The driving band c is then passed to
the loose pulley to allow of placing, fresh material between the
cylinders a, a, a².
It should be mentioned that the wheel m maintaining the communica-
tion of motion between the wheels and n, notwithstanding its vertical
displacement is mounted on a shaft w, turning round the fixed and
invariable point of connection to¹.. This shaft is shown in detail,

filed by the said Antoine Julien Deblon in the Great Seal Patent
Office on the 27th December 1871.

page_text: our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth 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,

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 "IMPROVEMENTS 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 one 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 improvements referred to relate to calendering machines for which
I obtained Letters Patent, under the No. 1918, and bearing date the 23rd
June 1869, and in which three or more cylinders are employed between
which the stuffs to be treated pass, these cylinders being animated by
a rotary reciprocating motion.
Fig. 1 is an end view of the machine, and Fig. 2 a front view.
The three cylinders a, a¹, a¹¹, between which the stuff to be calendered
is placed are mounted on the axes b, b1, b. The two lower cylinders
a, a', maintain an invariable position on their axes, but like the upper
cylinder a perform a rotary reciprocating motion in the following
manner-On the lower horizontal axis c three pullies d, d¹, d¹¹, are
mounted, the pulley is like the centre one d loose on its axis c,
whilst the other d is fixed to the same axis. With the pulley d" is a
cast-iron bevil pinion e governing the bevil wheel when the driving
band C circulates on that pulley, but when the band is conducted to the

page_text: of
pulley & this latter turning the shaft c occasions the movement of the
second pinion e¹, which in turn governs the bevil wheel f, the axis
of which moreover supports a toothed wheel g and pinion both loose
on the said axis. The pinion h gears with a great wheel i loose on the
axis of one of the lower cylinders. Behind the wheel i and connected
with it is a pinion j, which turns a wheel K keyed to the axis
the lower cylinder a¹; on this same axis b₁ is also fixed a gear wheel 7
which commands the four toothed wheels m, n, g, o, of the same
diameter as itself. The wheels m and g, loose on their axes, are the
intermediaries between the governing wheel and the two others n
and o, fixed on the axes 6, 6"; of the upper and lower cylinders a, a".
This backward and forward movement is indispensable to the rotary
reciprocating motion of the three cylinders a, a¹, a", and produces a
complete calendrage of the stuff placed between them.
When it is considered that the stuff is sufficiently calendered in one
direction the movement is altered by removing the strap or band C of
the pulley d" to that d. This displacement occurs automatically by aid
of a cleat or projection t connected to the side of the wheel K which
never makes a complete turn. This projection in coming in contact with
a lever "actuates the fork marked in dotted lines in both Figures,
and causes the strap C to pass from one pulley to the other in suchwise
that the several positions it is capable of giving this projection enables
the amplitude of the backward and forward movement of the cylinders
a, a, a, to be regulated.
If it is desired that the cylinders should always turn in one direction
it is sufficient to raise the projection. Besides its rotary reciprocating
.motion the upper cylinder al may be raised or lowered at will on its
cushions p, which enables the requisite pressure to be given to the stuff.
The following is the manner in which the ascension and descension of
the cushions p of the axis " is effected. Laterally with the machine two
loose pullies q, q', are arranged, on each of which a strap passes which
imparts to them alternately by aid of the coupling screw an opposite
motion according as it is desired to raise or lower the cushions p. On
the same shaft as the pullies q, q', a bevil pinion is keyed gearing
5 with a wheels, which in turn transmits motion to the spur wheel v by
means of the pinion u. The axis x of the wheel v is screw cut to
admit of its ascending and descending in a socket of the frame B of
the machine. The lower end of this axis receives one of the cushions p

page_text: of the cylinder a". The same arrangement of the spur wheel vand
screw is established for displacing the other cushion, but with the
concourse of a wheel y intermediary between the two gear wheels v, v.
This wheel y, by reason of the displacement it submits to (since it must
conform to the up and down movement of the wheels v), has its boss
or nave screw cut to receive a screw z of the same thread as the screw. x,
but disposed in a contrary direction.
When the cushions p can be lowered no further or when the pressure
on the stuff has attained its maximum the strap slides on the pulley q
or q', according to which governs the descent of the cushions.
If necessary one or two turns more may be permitted and the stuff
is then perfectly calendered. The driving band C is then passed to
the loose pulley d¹ to allow of placing fresh material between the
cylinders a, a¹, a¹¹·
It should be mentioned that the-wheel m maintaining the communi-
cation of motion between the wheels and n, notwithstanding its vertical
displacement, is mounted on a shaft w turning round the fixed and
invariable point of connection w¹.
Such is the nature of the improvements of which I claim the
exclusive privilege, reserving to myself the right of arranging the
several parts mentioned for effecting the vertical displacement of the
cushions of the upper cylinder, as well as modifying if requisite the
forms, dimensions, and materials constituting the several parts forming
the calendering machines herein mentioned and illustrated.
In witness whereof, I, the said Antoine Julien Deblon, liave here-
unto set my hand and scal, this Eighteenth day of December, in
the year of our Lord One thousand eight hundred and seventy-
one.
