1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign Patent
Solicitors, 6 Lord Street Liverpool, and 6 Bank Street Manchester both in the
County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to calendering rolls, and particularly to that class thereof to
be used for calendering and finishing muslin, print cloths, and similar textile fabrics,
the object being to provide an improved roll for said use, and the invention
consists in the peculiar construction of the roll, all as hereinafter fully described.
In the drawing forming part of this specification,
Figure 1 is a side elevation of a portion of a calendering roll constructed according
to the invention, a portion of the body of the roll shown in this Figure being shown
in longitudinal section to illustrate, as far as may be, the materials of which the roll
is composed.
Figure 2 is a perspective view of a portion of the roll, one end thereof being
shown broken off.
In the drawing, 4 indicates the ordinary shaft of a calendering roll, and 3 the
roll itself, which is, in practice, built up on the shaft 4, as below described, said shaft
being ordinarily provided with a fixed collar 6, near its journal at each end. A metallic
roll-head 5, is locked against the end of the roll 3, in any suitable manner, one means
of locking said roll being shown in the drawing, consisting of two segments 7 of a
split ring which are inserted in an annular groove in shaft 4, between the outer face of
said head 5 and the collar 6 on the shaft, in the positions shown in Figures 1 and 2,
whereby said head is rigidly locked against each end of the roll 3, and thereby such
connection is made between the latter and the shaft 4, as causes the shaft and the roll
to rotate, in use, as one.
The essential feature of novelty in the calendering roll which constitutes the subject
matter of this invention, consists in the combination of materials from which the roll 3
is made, said materials consisting of corn husks and cotton mixed or commingled in
a common mass by passing about equal portions of each substance through a coarse
lapper or carding machine whereby the husk material is more or less broken up and
suitably intermingled with the cotton.
In Figure 1, the said materials are, as far as practicable, illustrated in the sectional
portion of the roll there shown, and in that Figure, a indicates the cotton and e
portions of the husk matter.
The manner of constructing the roll from said materials is that ordinarily pursued
in making rolls from other similar ones, that is to say, the shaft 4 is placed in an
upright position with one of the heads, 5, thereon near its lower end, in or on a
suitable base under a hydraulic press. The mixed cotton and corn husks above
described are then applied and arranged in proper position around the shaft and
the said hydraulic press is brought to act to compress and solidify said material,
forcing it downward against the said head near its lower end, and little by little
more and more material is added to the roll and compressed as before, until the roll
shall have attained the desired length, when a second head is placed on the upper

end of the roll and forced against the latter by said press and is then locked in position
as described. The roll is then placed in a suitable lathe and is turned and finished
ready for use.
The calendering roll made as above described and consisting of the said combina-
tion of materials, possesses certain advantageous characteristics not possessed by rolls
heretofore made, said characteristics being those particularly adapted to the finishing
of textile materiál of the classes above referred to, in that the cotton portion of
the roll provides the requisite finishing and surface-polishing material, and the
husk portion of the material of the roll provides an elastic feature not possessed by
the cotton alone, and the husk portion of the roll causes the latter to so act upon the
fabric against which it rolls that the threads thereof are not injuriously flattened,
for the reason that the face of the roll permits of certain temporary indentations
therein which may be caused by the fabric, but which indentations, owing to the
elastic action of the husk material, are of only temporary duration, and hence such
indentations or marks as may be impressed on the face of the roll in use cause no
permanent injury thereto.

Improvements in or relating to Calendering Rolls, Applicable for
Calendering and Finishing Muslin, Print Cloths, and similar

A communication from abroad by THE GRANGER FOUNDRY AND MACHINE COMPANY,
a corporation of and doing business in Providence, County of Providence and
State of Rhode Island, United States of America, said Company having its
place of business at the corner of Gaspee and Francis Streets in said
Providence.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 323 High Holborn, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to calendering rolls, and particularly to that class thereof to
be used for calendering and finishing muslin, print cloths, and similar textile fabrics,
the object being to provide an improved roll for said use, and the invention consists
in the peculiar construction of the roll, all as hereinafter fully described and pointed
out in the claim.
In the drawing accompanying the provisional specification,
Figure 1 is a side elevation of a portion of a calendering roll constructed
according to the invention, a portion of the body of the roll shown in this Figure
being shown in longitudinal section to illustrate, as far as may be, the materials of
which the roll is composed.
Figure 2 is a perspective view of a portion of the roll, one end thereof being shown
broken off.
In the drawing, 4 indicates the ordinary shaft of a calendering roll, and 3 the roll
itself, which is, in practice, built up on the shaft 4, as below described, said shaft
being ordinarily provided with a fixed collar 6, near its journal at each end. A
metallic roll-head 5, is locked against the end of the roll 3, in any suitable manner,
. one means of locking raid roll being shown in the drawing, consisting of two
segments 7 of a split ring which are inserted in an annular groove in shaft 4, between
the outer face of said head 5 and the collar 6 on the shaft, in the positions shown in
Figures 1 and 2, whereby said head is rigidly locked against each end of the roll 3,

page_text: and thereby such connection is made between the latter and the shaft 4, as causes the
shaft and the roll to rotate, in use, as one.
The essential feature of novelty in the calendering roll, which constitutes the
subject matter of this invention, consists in the combination of materials from which
the roll 3 is made, said materials consisting of corn husks and cotton mixed or
commingled in a common mass by passing about equal portions of each substance
through a coarse lapper or carding machine whereby the husk material is more or
less broken up and suitably intermingled with the cotton.
In Figure 1, the said materials are, as far as practicable, illustrated in the sectional
portion of the roll there shown, and in that Figure, a indicates the cotton and c
portions of the husk matter.
The manner of constructing the roll from said materials is that ordinarily pursued
in making rolls from other similar ones, that is to say, the shaft 4 is placed in an
upright position with one of the heads, 5, thereon near its lower end, in or on a suit-
able base under a hydraulic press. The mixed cotton and corn husks above described
are then applied and arranged in proper position around the shaft and the said
hydraulic press is brought to act to compress and solidify said material, forcing it
downward against the said head near its lower end, and little by little more and more
material is added to the roll and compressed as before, until the roll shall have
attained the desired length, when a second head is placed on the upper end of the
roll and forced against the latter by said press and is then locked in position as
described. The roll is then placed in a suitable lathe and is turned and finished ready
for use.
The calendering roll made as above described and consisting of the said combina-
tion of materials, possesses certain advantageous characteristics not possessed by rolls
heretofore made, said characteristics being those particularly adapted to the finishing
of textile material of the classes above referred to, in that the cotton portion of the
roll provides the requisite finishing and surface-polishing material, and the husk
portion of the material of the roll provides an elastic feature not possessed by the
cotton alone, and the husk portion of the roll causes the latter to so act upon the
fabric against which it rolls that the threads thereof are not injuriously flattened, for
the reason that the face of the roll permits of certain temporary indentations therein
which may be caused by the fabric, but which indentations, owing to the elastic
action of the husk material, are of only temporary duration, and hence such indenta-
tions or marks as may be impressed on the face of the roll in use cause no permanent
injury thereto.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
A calendering roll for finishing cloth consisting of commingled corn husks and
cotton, substantially as set forth.
