Improvements in connection with Calenders for Finishing Textile
Fabrics.
I, RALPH CLEGG of 62 Wellington Place, Longsight, Manchester in the county of
Lancaster, Mechanical Engineer do hereby declare the nature of this invention to be
as follows
My invention relates to a machine or apparatus by means of which continuous or
endless running of textile fabrics through calenders during finishing processes &c. is
maintained, thereby adding greatly to the aggregate amount of work otherwise
possible to be done-where the alternative is for example to pass each piece or batch
of cloth by itself or separately through the calender which in such case necessarily
runs empty in the interval between the completion of the one and the introduction
of every succeeding piece of fabric.

My object of continuous or endless running is accomplished by causing, by the
machine above referred to, an accumulation of the cloth, held in suspension and in
advance so to speak of the calender and placing the same in such a position as to be
taken up conveniently and regularly by the calender, such accumulation affording to
the employes or attendants sufficient time to attach or connect the last end of the
cloth so held in reserve and in course of being operated upon to the first end of
another piece of cloth for similar treatment and to be also in turn operated upon
by the calender, and so on in like manner with other pieces so long as the process of
what I have termed endless or continuous running may require to be continued with
any lot or lots of cloth, the effect being that during such time there will be no
empty" running of the calender.

My invention may be described as consisting of framework having hearings
carrying a pair of draw rollers. Immediately under or rather before the rollers are
a pair of brackets which receive the pivots of the shaft or rod carrying the box (50
called in the trade) with the cloth upon it In a convenient position out of the way
of the batch or box of cloth and draw rollers is a shaft upon which cams are fixed.
Fixed to the sides of the framework are brackets serving as fulcrums of levers
having projections, which projections work in the before mentioned cams. At the
extremity of the before mentioned levers are short swivel levers the purpose of which
will hereinafter be described At each side of the framework other levers are pro-
vided working in separate cams These levers give to the swivel levers above-named
by means of connecting rods, a peculiar motion. The ends of the levers with the
projections before mentioned opposite to those of the fulcrums describe an arc and
carry the swivel levers in that direction
Immediately over the swivel levers when in a certain position hereinafter explained,
is a passage or guide extending upwards, at the end of which passage or guide is a
chamber of sufficient size to receive a number of rods. These rods may be of wood,
iron, brass or any other suitable material and extend sufficiently across the framework.
At the extremity of the arc, described by the above mentioned levers are a pair of
curved guides which serve as carriers or supports of the rods which the swivel
levers by means of the levers with the projections deposit into them stroke by
stroke.
The rods in dropping down the passage from the chamber are caught one by one
by the swivel levers which at the commencement of the stroke are immediately under
the passage or guide before mentioned. Each rod is carried forward until it arrives
at the extremity of the arc when it is released and drops into the curved guides or
supports. The swivel levers which may now be called the rod carriers now return to
repeat the process. The draw rollers are driven by a strap from the calender and as

soon as a certain fixed length of cloth is delivered by them off the box or batch the
lowest rod in the passage or guide as aforesaid is drawn forward and deposited at the
end of the arc described by the levers, and the cloth being still delivered by the rollers,
folds over this rod and continues so to do until the regulated length as aforesaid is
reached when another rod is drawn out and carried forward and the process-repeated
throughout.
This process goes on constantly until a sufficient accumulation of cloth hanging in
a series of folds over the rods which the curved guides support, mas taken place to
give to the attendants sufficient time to attach the two ends together as before
explained, to ensure continuous full running of the calender
A further part of my invention is the arrangement for releasing the shaft o rod
carrying the batch of cloth or rather box now exhausted from the brackets which at
each end support it It consists of two brackets, one at each side of the frame, each
having bearings somewhat like the 3 sides of a square, one of the sides of which forms
part of a lever and is moveable
These levers have at the other extremities inclines The attendant places a full box
or batch having another shaft or rod inside it, upon two other supports and when it
is desired to remove the empty box and replace it by a full one, the tull one is pushed
forward and the pivots of the shatt or rod carrying the full batch coming against the
inclines on the ends of the said levers, lift the other ends which as before mentioned
form part of the bearings for the box when in a working position This movement
leaves a clear opening on one side of each of the bearings and the full box coming
in contact with the empty one, pushes it out when it falls down into curved arms
ready for the attendant to pick up.

Improvements in connection with Calenders for Finishing Textile
Fabrics.
I. RALPH CLEGG of Wellington Place, Iongsight, Manchester, in the County of
Lancaster, Mechanical 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 :-
My invention relates to a machine or apparatus-by means of which continuous or
endless running-of Textile Fabrics, through calenders during finishing processes, &c,
is attained, thereby adding greatly to the aggregate amount of work otherwise possible
to be done where the alternative is, for example, to pass each piece or batch of cloth
by itself or separately through the calender, which in such case necessarily runs
"empty in the interval between the completion of the one & the introduction of
every succeeding piece of fabric My invention will be readily understood by reference
دو
to the accompanying drawings
My object of continuous or endless running is accomplished by causing an accumu-
lation of the cloth, held in suspension, and in advance, so to speak, of the calender,
such accumulation affording the employés or attendants sufficient time to attach or
connect the last end of the cloth so held in reserve and in course of being operated
upon to the first end of another piece of cloth to be operated upon, and so on in like
manner with other pieces, the effect being that during such time there will be no
empty" running of the calender.

In the accompanying drawings A. A. represent the framework of the machine,
having bearings can ying a pair of draw rollers B. B¹ Immediately under, or rather
before the rollers are a part of brackets CC. which receive the pivots of the shaft or
rod carrying the box, ((so called in the trade) with the cloth upon it D is the
shaft upon which cams E. E' are fixed. This shaft is driven by a strap from the
draw roller B. F. are brackets fixed to the sides of the frame and carry studs upon

page_text: which work the levers G G¹, motion being given them by the cums E E¹ acting upon
the bowls HH¹ At the extremity of the levers G, are swivel lovers K. These
swivel levers are connected to the levers G¹ by the rods L. and are carried from the
point M, to M³, & from M¹ to M as shown by the dotted lines, by the levers G. At
the point M, is a passage or guide O extending upwards, at the end of which passage
or guide O. is a chamber P. of sufficient size to receive a number of rods N. N. N.
These rods may be of iron, brass, or wood and extend sufficiently across the frame-
work.
The object of the swivel levers is to carry the rods N. N, one at a time, from the
point M to the point M. When the swivel levers K, are at the point M, they are
moved up at one end by the lever G¹ by means of the rod L so that they embrace a
rod N at each end so as to enable them to draw the rod from the passage O, and carry
it forward to M'.
The cams are suitably shaped so as to give the necessary motion to the levers.
When one rod is being deposited at M³ it throws the preceding one down the curved
guides which serve as carriers or supports to the rods as they drop down with the
cloth hanging over them. The draw roller B is driven by a strap on the pulley S
from the calender, and as soon as a certain fixed length of the cloth is delivered, the
lowest rod in the passage O is drawn forward by the swivel lovers K and deposited at
the point M, and the cloth being still delivered by the rollers. "folds" over this rod,
and when the regulated length is again reached, another rod is drawn out as before
& carried forward & the process repeated until one piece or batch of cloth is exhausted
when the machine is stopped so as to enable the attendant to attach the last end to the
first end of the next piece or batch. By this time a sufficient accumulation of cloth
has taken place, hanging in a series of folds L' over the rods on the curved supports
so as to give the attendant sufficient time for the purpose before explained.
As the calender takes up the cloth, the rods N when they have no longer any
cloth over them are drawn over the part Y and drop into the box Y¹ The arrow Z
represents the direction in which the cloth is passing to the calender.
A further part of my invention is the arrangement for releasing the shaft or rod
carrying the batch or box of cloth now exhausted from the brackets which at each end
support it. It consists of two brackets C C. one at each side of the frame, each
having bearings somewhat like the three sides of a square, one of the three sides of
each forming part of the lever T and can be lifted up so as to leave one side of each
bearing clear or open. These levers T have at each end an incline U. When it is
desired to remove the empty box and replace it by a full one, the full one is pushed
forward from the point U¹ and the pivots of the shaft carrying the full box coming
against the two inclines U on the levers T, lift the ends forming one of the three sides
of each bearing, which hitherto secured the pivots of the box when being operated
upon.
The full box is thus forced forward against the empty one & throws it out of the
bearing now open Under each bracket C C are curved arms W in position to
receive the dropping box & deposit it in a position for the attendant to pick up con-
veniently
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim 13,
1st. A machine or apparatus by means of which continuous or endless running of
textile fabrics through calenders during finishing processes &c. is attained having
folds L of cloth or fabric hanging on rods arranged substantially in the same manner
herein before described and indicated by the drawings hereunto annexed.
2ud. The arrangement for carrying the rods from one point to another, which
arrangement consists in the cams E. E' levers G G' swivel levers K. rods L. passage O.
chamber P all arranged and employed in conjunction with each other for the purpose
and substantially in the same manner hereinbefore described and indicated by the
drawings hereunto annexed.
