IMPROVEMENTS IN THE CONSTRUCTION OF "DOUBLING WINDING FRAMES
Year: 1884

page_text: We THOMAS BRIGGS Manufacturer and EDWARD WEBB Manager both of
Richmond Hill Works Salford in the County of Lancaster, do hereby declare the
nature of our invention for IMPROVEMENTS IN THE CONSTRUCTION OF "DOUBLING
WINDING FRAMES" to be as follows:-
This Invention relates to improvements in the construction of Machines known
as Doubling winding Frames for doubling and winding yarns or threads in two or
more folds of equal lengths and tension laid together side by side without twisting
upon one bobbin. In carrrying out our Improvements we place the creel
containing the bobbins of single yarn above the frame and contrary to the usual
method in winding but similar to the ordinary arrangement in twisting, we draw
the threads downwards over and under rods, then round a large roller of very light
construction either covered with perforated steel or upon which is a number of
small pressing rollers one bearing upon each thread and preventing it slipping, this
roller is rotated by the threads and at the same time from its position and
construction, it serves to regulate and equalize the quantity of yarn drawn from
the bobbins From this roller the threads or yarns pass through the eyes of the
drop pins thence over a rod direct to the winding-on bobbins.
Across the front of the frame, about eighteen inches above the floor line, extends
a shaft fitted with drums; each of the bobbins. for the reception of the yarn rests
upon and is driven by frictional contact with one of these drums; around the
bobbin (and holding it in the necessary position upon the drum) is a frame, hinged
to a rod passing from end to end of the frame behind the drums, the hinge
admitting of the necessary rise of the bobbin in the process of filling-Passing
along one side of this frame, and working upon the same rod, is a lever on the
upper side of the front end of which is cast or cut a number of ratchet teeth into
which a pawl, attached to the side of the bobbin frame engages-At the opposite
end of the lever is suspended a weight sufficient to raise the bobbin and frame out
of contact with the drum. Attached to the same end of the lever as the weight,
is a chain which passes round a small pulley fixed upon a rod supported by the
rails of the frame, immediately over the aforenamed lever-At the opposite end of
the rod just referred to, and in front of the frame is a small crank or handle which
when forced down revolves the rod and small pulley upon which the chain is

page_text: wound, thus raising the weight, and end of the lever, at the same time lowering
the opposite end which supports the bobbin frame and bringing the bobbin into
contact with the friction drum.
The small crank or handle above referred to is held in position by a latch, acted
upon by a small lever which is attached to the oblong frame containing the usual
detector pins.
Immediately behind and just below this oblong frame is a revolving shaft upon
which are fitted a number of bosses with projections thereon, so that when a thread
breaks or a bobbin runs empty its corresponding pin drops and one of the
projections coming into contact with it, acts upon the lever supporting the oblong
frame, withdrawing the latch and releasing the handle causing the weighted end of
the lever to fall and raising the opposite end carrying the bobbin out of contact
with the drum and at once stopping the winding.
Another part of our invention consists in the construction of separate brakes
acting simultaneously upon each of the bobbins in the creel in such a manner as to
prevent them from overrunning upon the sudden stopping of the machine; these
are so arranged that immediately the machine is started the brakes are raised out
of contact with the bobbins by a rod worked by a small lever attached to the
before named crank or handle for starting the winding.
The advantages claimed for this improved construction of doubling winding
frame are 1 That by the peculiar construction and arrangement of the large
covered roller referred to the serious defect (apparent in many doubling winding
frames) where no reliablé provision is made for equalizing the length of the yarns
or threads is remedied and we are enabled by the before named roller together
with the general arrangement of the frame, to produce bobbins of double wound
yarn or threads, of any reasonable number of folds of unvarying length and tension,
and 2. The method of applying a brake to each separate bobbin of single yarn in
the creel as described entirely prevents the overrunning of the bobbins upon the
sudden stopping from the very high speed at which we are consequently enabled
to conduct the operation of doubling winding.

page_text: Wo THOMAS BRIGGS Manufacturer and EDWARD WEBB Manager both of
Richmond Hill Works Salford in the County of Lancaster do hereby declare
the nature of our invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
DOUBLING WINDING FRAMES," 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 improvements in the construction of machines known
as doubling winding frames for doubling and winding yarns or threads in
two or more folds of equal lengths and tension laid together side by side
without twisting, upon one bobbin; and in order that the same may be clearly
understood we have annexed hereunto a sheet of drawings and have marked the
same with figures and letters of reference corresponding with those in the following
description.
Fig 1, is a transverse section of a double winding frame constructed according
to our invention.
Fig 2, is a front elevation of one "section" of the machine.
Figs 3 and 4 are detached views of the stop motion hereinafter described.
In carrying out our improvements we place the creel a. a containing the
bobbins of single yarn b. b. b. above the frame and contrary to the usual method in
winding but similar to the ordinary arrangement in twisting, we draw the threads
downwards over a rod c. c. then round a large roller d. d. of very light construction
either covered with perforated steel or upon which is a number of small pressing
rollers one bearing upon each thread and preventing it from slipping; this roller d. d
is rotated by the threads, and at the same time, from its position and construction
it serves to regulate and equalize the quantity of yarn drawn from the bobbins.
From this roller d. d the threads or yarns pass through the eyes of the drop pins e. e
thence over a rod f. f. direct to the winding on bobbin g. g. Across the front of the
frame, about eighteen inches above the floor line, extends a shaft h. h fitted with
drums i. i.
Each of the bobbins for the reception of the yarn rests upon and is driven by
frictional contact with one of these drums; around the bobbin g. g (and holding it
in the necessary position upon the drum ii) is a frame k. k. hinged to a rod behind
the drum i. i. the hinge admitting of the necessary rise of the bobbin in the process
of filling. Passing along one side of this frame k. k. and working upon the same
rod l. l. is a lever m. m on the upper side of the front end of which is cast or cut a
number of ratchet teeth into which a pawl or pawls n. n attached to the side of the
bobbin frame k. k engages. At the opposite end of the lever is suspended a
weight o. o sufficient to raise the bobbin g. g and frame k. k out of contact with
the drum ii. Attached to the same end of the lever as the weight is a chain
which passes round a small pulley or sector p. p. fixed upon a rod q. q supported
At the
by the rails of the frame immediately over the aforenamed lever m. m.
opposite end of the rod q. q. just referred to, and in front of the frame, is a small,
crank or handle r. r. which when forced down revolves the rod q. q and small pulley
or sector P.p upon which the chain is wound, thus raising the weight o. o and the
end of the lever m. m at the same time lowering the opposite end which supports
the bobbin frame k. k and bringing the bobbin g. g into contact with the friction
drum i. i.
The small crank or handle r. r above referred to is held in position by a latch 8.8
acted upon by a small lever t. t. which is attached to the oblong frame containing
the usual detector or drop pins e. e
Immediately behind and just below this oblong frame is a revolving shaft upon
which are fitted a number of bosses u. u with projections thereon one boss to each

page_text: set of drop pins so that when a thread breaks or a bobbin runs empty its corre-
sponding pin e drops and one of the projections coming into contact with it, acts
upon the lever t. t. supporting the oblong frame withdrawing the latch 8. 8 and
releasing the handle r. r causing the weighted end of the lever m. m to fall and
raising the opposite end carrying the bobbin g. g out of contact with the drum and
at once stopping the winding.
We prefer to mount the boss u. u loosely on the shaft and to cause it to revolve
by means of a boss u¹ u¹ provided with a face plate and projection and mounted on
a feather on the said shaft. This boss u¹ u¹ is moved away from the boss u. u by
the small lever ulu on the rod q. q when the section is thrown out of gear and
thus the projections on the boss u. u are not constantly coming into contact with
the drop pins when the "section" is stopped.
Another part of our invention consists in the construction of separate brakes v. v
acting simultaneously upon each of the bobbins b. b. b in the creel a. a in such a
manner as to prevent them from overrunning upon the sudden stopping of the
machine; these are so arranged that immediately the machine is started the
brakes are raised out of contact with the bobbins by, a rod w. w worked by a small
lever x. x on the before named rod q. q on which is fixed the crank or handle r. ↑
for starting the winding.
The advantages claimed for this improved construction of doubling winding frame
are-
(1.) That by the peculiar construction and arrangement of the large covered
roller referred to the serious defect (apparent in many doubling winding frames)
where no reliable provision is made for equalizing the length of the yarns or
threads) is remedied and we are enabled by the before named roller together with
the general arrangement of the frame to produce bobbins of double wound yarn or
threads, of any reasonable number of folds of unvarying length and tension.
(2). The method of applying a brake to each separate bobbin of single yarn in
the creel as described entirely prevents the overrunning of the bobbins upon the
sudden stopping from the very high speed at which we are consequently enabled to
conduct the operation of doubling winding.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is—
c
1. The construction and application of the roller for the purpose of equalizing
the quantity and tension of the yarn drawn from the bobbins.
2. The adaptation of a brake to each separate bobbin of single yarn in the creel
so as to prevent the overruning of the bobbins on the sudden stoppage of the
frame.
3. The weighted lever and its adjuncts for automatically raising. the bobbin out
of contact with the driving drum whenever a thread breaks or the bobbin runs
empty.
All substantially as hereinbefore more particularly described and illustrated by
the drawings hereunto annexed.
