PROVISIONAL SPECIFICATION.
Improvements in Calendering Apparatus.
We, THOMAS PICKLES and JOSEPH HENRY PICKLES of Cairo Mills Burnley, Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
The improvements relate to calendering apparatus for the finishing or calendering
of cotton or other goods, and have for object the reducing of the number of paper or
other fibre bowls or rollers in such apparatus and thus reducing the expense of con-
struction. Calendering apparatus, as at present for the most part employed, is
constructed with four horizontal bowls or rollers mounted one over the other. These
bowls or rollers are composed two of paper or fibre compressed, and two of iron or
other metal, and placed alternately, so that a metal bowl always comes in contact with
a paper one. To accomplish which it will be seen that two metal and two paper bowls
are needed.
Now the cost of paper or other fibrous bowls is greatly in excess of metal, hence we
desire to so arrange the bowls or rollers that one paper or fibrous bowl may serve to
three metal ones.
To accomplish this and to effect our improvements, we mount two metal bowls or
rollers as the lower portion of the apparatus in or about the same plane one behind
the other but not touching each other.
We then mount one paper or fibrous bowl or roller so as to rest or press on both
these metal rollers at the same time, and over the top of this paper or fibrous roller I
mount another metal roller. All the roliers are mounted in suitable bearings and are
provided with the usual appliances and gearing for giving pressure and motion
thereto.
The cloth is passed between the paper and the front bottom metal roller, thence
between the paper and back metal roller, thence over the paper roller and under
the top metal roller, and over the latter for delivery at the back of the machine.
Variations in detail both ot form and material may be made without departing
from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements in Calendering Apparatus.
We THOMAS PICKLES and JOSEPH HENRY PICKLES of Cairo Mills Burnley, Manu-
facturer, 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 :—
The improvements relate to calendering apparatus for the finishing or calendering
of cotton or other goods, and have for object the reducing of the number of paper
or other fibre bowls or rollers in such apparatus, and thus reducing the expense of
construction.
Calendering apparatus, as at present for the most part employed, is constructed
with four horizontal bowls or rollers mounted one over the other.
These howls or rollers are composed two of paper, or fibre compressed, and two of
iron or other metal, and placed alternately, so that a metal bowl always comes in
contact with a paper one. To accomplish which it will be seen that two metal and
two paper bowls are needed.

page_text: Now the cost of paper or other fibrous bowls is greatly in excess of metal, hence we
desire to so arrange the bowls or rollers that one paper or fibrous bowl may serve to
three metal ones.
To accomplish this, and to effect our improvements, we mount two metal bowls or
rollers as the lower portion of the apparatus in or about the same plane one behind
the other but not touching each other.
We then mount one paper or fibrous bowl or roller so as to rest or press on both
these metal rollers at the same time, and over the top of this paper or fibrous roller,
we mount another metal roller.
All the rollers are mounted in suitable bearings aad are provided with the usual
appliances and gearing for giving pressure and motion thereto.
The cloth is passed between the paper and the front bottom metal roller, thence
between the paper and back metal roller, thence over the paper roller and under the
top metal roller, and over the latter for delivery at the back of the machine.
In the accompanying drawing, which is a sectional elevation, the arrangement of
the bowls is illustrated, but the various details for driving, and giving pressure, or
the like are omitted as unnecessary to be shewn.
a. a is the first bowl, which is of metal; b. b is the second bowl which is also of
metal, while c. c. is the third bowl, which is the paper or other fibrous bowl, and is
mounted so as to be upon and in contact with both the bowls a. a. and b. b.
d. d is the fourth bowl, which is of metal, and is placed so as to be upon and in
contact with the paper or fibrous bowl c. c.
In the example shewn this bowl is placed over the centre of the paper bowl; but
this may be varied to a considerable extent with the like result.
In like manner the bowls a. a and b. b. may be mounted so as to deviate considerably
from the horizontal line, and other variations may be made in the various details
without departing from the peculiar character of the invention.
The cloth passes between the bowls in the direction indicated by the arrows, and
may be fed and delivered to and from the calender in the ordinary or other
manner.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
In Calendering Machines the combination of three metal bowls with one paper
or fibrous bowl arranged so that all three metal bowls come in contact with the
one paper or fibrous bowl, for the purpose and in manner substantially as herein
shewn and described.
