I, FRANK REYNOLDS, of 16, Fore Street, Westbury, in the county of Wilts,
clothworker, do hereby declare the nature of this invention to be as follows :-
<<
:-
The object of this invention is to obviate the production of what are known as
streaky" cloths, caused by uneven warps or "chains," due to the varying tension of
the threads between the cops or bobbins, and the "slay or frame into which the
threads are gathered before passing to the warping machine.
"
Instead of being arranged in triangular and pyramidal form, as heretofore, the cop
or bobbin rails are, under this invention, arranged in straight rows one behind the other
between the sides of the frame, each rail being placed higher than the other from the
front towards the back.
By this arrangement there is less difference in the distance which each thread has
to travel and, consequently, greater uniformity of tension in this respect.
Suspended on a rod extended across the frame in front of each perforated guide
plate is a series of weights, one for each thread. Below the wire by which each weight
is suspended is passed a thread which is thus made to intervene between the underside
of the wire of the weight and the top of the rod on which the weights are suspended.
Beyond this rod and the corresponding rod of each guide-plate and further to the
front is a second rod over the top of which the threads are passed.
Each guide-plate receives the threads from two cop or bobbin rails so that the mass
of threads is rendered more compact, and access to the bobbins or cops and other parts
is facilitated. The threads from one of the two cop or bobbin rails pass direct through
the guide-plate and the threads from the other pass first over a guide rod behind the
guide plate and thence through the guide-plate. The holes in the guide plate are
preferably trumpet mouthed at each side of the plate.
By the weights bearing thereon, as aforesaid, each thread is prevented from running
unduly slack to the warping machine, and, should a thread become unduly tight
between its weight and the cop or bobbin, the weight is raised thereby and the friction
over the outer rod being reduced, the tension on the thread is relieved correspondingly.
As the undue strain between the weight and the cop or bobbin decreases, the weight
is lowered and the friction increased to the requisite degree.
By means of this brake automatically exerted upon the several threads, the warp or
ID 077

page_text: "chain" produced in the warping machine has an even tension throughout and thus
the occurrence of a slack thread or streaks in the cloth is prevented.
By means of wire pegs formed to act as springs, and upon which the bobbins or cops
are placed, the bobbins or cops are firmly held. The bobbins bear below on the rails
and are thus kept steady.

Improvements in the Cop or Bobbin Frames of Warping and
other similar Machines.
I, FRANK REYNOLDS, of Bank Street, Melksham, in the County of Wilts, clothworker,
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:-
According to this invention the cops or bobbins, instead of being arranged in
triangular and pyramidal series, as ordinarily, are disposed on rails in horizontal
parallel rows, the height of each rail from the base increasing from the front towards
the back of the frame.
By this arrangement of bobbins the distance of the threads from the point of con-
vergence is reduced and the angle of convergence eased. Consequently the strain on
the more distant threads is lessened and a greater uniformity of tension obtained.
In order to equalize the tension on all the threads as they leave the frame, weights
are employed and are suspended from a rod stretched across the front of the frame.
These weights are carried in holders of wire which holders may conveniently be termed
brackets. There are as many brackets as threads and each thread is passed under the
top of its bracket and between it and the rod from which, as aforesaid, the brackets
are suspended. The weight carried by each bracket bears upon its respective thread.
Behind each row of weights, is a perforated guide plate and behind each guide plate is a
rod extending across the frame in a plane parallel to that of the rod from which the weights
are suspended. A similar rod is extended across the frame in front of the guide plate.
Each guide-plate receives the threads from two rows of cops or bobbins, that is to say,
in a frame having eight rows of bobbins, four guide plates are required. It will be
convenient to consider the cops or bobbins as arranged in series of two rows each, a
front row and a back row. The bobbins in the back row are placed intermediate
between those in the front row for convenience, for economy in space and in order to
render the mass of threads more compact and the bobbins easier of access. The threads
from the front row are carried up and passed directly through the perforations in the
guide plate. The threads from the back row are first passed over the rod extended, as
aforesaid, behind the guide plate and are then passed through their proper perforations
in the plate. The threads from both rows of bobbins are conducted from the guide
plate over the top of the rod by which the weighted brackets aforesaid are supported

page_text: and are, as above mentioned, made to intervene between the underside of the wire of
which the bracket is composed and the top of the rod by which the bracket is
suspended. Thence the threads are conducted to and converge towards the "slay" of a
warping or other machine.
To assist in equalizing the tension thereon, the threads are passed between the
underside of the tops of the brackets and the upper part of the suspension rod in such
manner that those threads which are to the right of the centre of the frame are inserted
from the right under the brackets and those which are to the left of the centre are
inserted from the left.
The weights act as brakes upon the threads and prevent them from running at
different degrees of freedom to the warping machine, and should a thread become
unduly tight between its weight and the cops or bobbins, the weight is raised by the strain
and thus the friction previously exerted on the thread between the bracket and the
suspension rod is reduced and the tension relaxed accordingly. When the undue
tightness of the thread ceases the thread is depressed by the weight which tends to
return it to its normal position.
"
The tension on the threads being at all times regulated and rendered uniform by the
action of the weighted brackets the production of what are known as
"streaks ог
« sectional divisions," due to varying tension, in cloth is obviated.
To secure the cop or bobbins firmly in place and to assist in maintaining them steady
special pegs to receive them are employed. These pegs are composed of a frame of
wire bent or formed so that when a bobbin is placed on such peg the wires are
compressed or forced closer together and act as springs against the interior of the
bobbin.
Referring to the accompanying 2 sheets of illustrative drawings, Fig. 1, Sheet 1
represents an end view of a cop or bobbin frame constructed and arranged in
accordance with this invention. The figure on Sheet 2 represents a front elevation
thereof. In this figure gaps or breaks are for convenience in drawing left.
Instead of being, as hitherto, arranged in a triangular frame and in triangular and
pyramidal form the cops or bobbins a, a¹ are disposed on rails A, A' arranged after
the manner of steps rising from the front to the back of the frame."
By this arrangement of bobbins the distance of the threads from the point of
convergence is reduced and the angle of convergence eased.
Consequently the strain on the more distant threads is lessened and a greater
uniformity of tension obtained.
Perforated guide plates 6 are extended at intervals across the frame. Behind each
guide plate is a rod c and in front of each guide plate is a rod d. At a short distance
in advance of each guide plate is a rod e carrying as many weighted brackets f as there
are cops or bobbins. By a plate g extended across the frame below each suspension
rode and recessed at both sides the weighted brackets are kept at the requisite
distance apart and are guided in their vertical movement.
At Fig. 2, Sheet 1 is represented at an enlarged scale and in side elevation a
bracket. The bar or arm e¹ prevents the bracket from rising unnecessarily high.
Two separate weights and e³ are shown and one or both may be employed according
to the nature of the yarns or threads.
Each guide plate receives the threads from two rows of cops or bobbins. The threads
from each row of bobbins a are carried up directly to the back of their respective guide
plates and inserted in their proper holes or perforations therein.
The
Those from the rows a¹ are carried up and passed over the rear rods c and
conducted thence through the perforations in the guide plates which are inter-
mediate between those through which the threads from the rows a are passed. The
cops or bobbins are as shown, disposed accordingly on the rails À A¹.
perforations or holes in the guide plates are preferably trumpet or bell-mouthed
and are rounded at that part on which the threads lie. From the perforations in the
guide plates all the threads are conducted over the top of the rod e from which are
suspended the weighted brackets f. The threads are passed below the underside of the
wires of which the bracket frames are composed and intervene between them and the

page_text: top of the rods e. The weighted brackets or regulators consequently act as brakes on
the threads and hence any slackness occurring between a bobbin and a weighted
bracket is corrected by the latter and should a thread become unduly tight between a
bobbin and a weighted bracket the bracket is raised by the strain on the thread and
the tension eased. As the tightness ceases so the weighted bracket relapses towards
its normal position on the wire from which it is suspended.
The threads thus fed to the "slay" of a warping machine, or otherwise gathered for
other machines, have an uniform tension whereby the production of what are known
as sectional divisions or streaks in cloth is obviated. Towards the bottom the frame is
furnished with a box for containing cops or bobbins or other materials. To assist in
equalizing the tension thereon, the threads are passed between the underside of the
tops of the bracket and the upper part of the suspension rod in such manner that those
threads which are to the right of the centre of the frame are inserted from the right
under the brackets and those which are to the left of the centre are inserted from
the left.
At Fig. 3 sheet 1 is represented an inside view and at Fig. 4 an end view of a
convenient form of plate and attendant mechanism for attachment of the rods and
plates employed in the machine.
The rod or wire e for the weighted brackets passes through the shank / carrying the
link which is adjustable in the slot k and is clamped when set by the nuts l, m. The
plate 9 by which, as aforesaid, the weighted brackets are kept at the requisite distance
apart is held in the clip n adjustable in the link i and clamped when set by the nut o.
The rod or wire e is strained through the medium of the nut p the rod being provided
towards the outer end with screw threads therefor.
At Fig. 5, sheet 1 is represented an improved peg for the cops or bobbins. It is
composed of wires which at the top are intertwined and made to constitute a frame the
lower part of which being compressed by the act of placing a bobbin thereon acts as a
spring against the bobbin and maintains it steadily and securely in place.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, I declare that what I claim is :-
1. In a frame for cops or bobbins, arranging the rails thereof in straight and parallel
rows ascending in the form of steps from the front towards the back whereby the
distance from the point of convergence of the threads is reduced and the angle of
convergence of the more distant threads lessened, substantially as described.
2. In a cop or bobbin frame the employment of weighted brackets or pendants such
as suspended from a convenient rod such as e and bearing upon the threads whereby
they are prevented from running unduly slack or tight to the "slay" of a warping
