Improvements in Machinery or Apparatus for Winding Yarn
or Thread.
I JAMES EDWARD BROADBENT. of Stalybridge in the County of Chester,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates principally to machines for winding yarn on bobbins or
tubes usually called quick traverse winding frames, and the object of the invention
is to simplify. the motion for actuating the traverse or slide bar and at the same
time render it capable of being driven at a very high speed, and also capable of
adjustment to vary the length of the traverse.
The invention cousists in connecting the said traverse or slide bar by a link
(preferably adjustable as to its length) to a crank pin carried by a sliding block to
which motion is given by the following means.
The block is mounted so as to be
capable of sliding in or upon a lever or its equivalent fixed upon a cross shaft at
one end of the frame, and on a level with the said traverse or slide bar. The block
is also provided with a bowl running in a grooved cam or plate fixed to the frame
and parallel with the orbit or plane of rotation of the said block. The groove of
this cam is so curved around the centre of the shaft above named that it regulates
the speed of the throw or traverse of the slide bar so as to compensate for the slow
motion of the crank pin in passing the horizontal centres and make a sharp return
at either end of the traverse thus effecting by a simple modification of the crank
motion what is usually done by a lever and a heart or circular cam, or other more
complicated device.
The crank pin by which the link is connected to the block is or may be adjustable
in a groove in the latter or otherwise so that although the traverse of the bowl in
its groove is constant that of the crank pin may be increased or decreased according
to the length of bobbin required.
In some cases the block slides upon its lever which is in the form of a rod and it
is prevented from turning.thereon by passing the crank pin through a small block
sliding in a radial groove in a second lever fixed on the said shaft and coinciding
with the direction of the first lever.
Or the lever first named may be made in the form of a slotted or grooved box
either square or cylindrical. In these cases the second lever is dispensed with and
in the latter case blocks are employed in the slots to keep the aforesaid sliding
block from turning in its lever.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Winding Yarn
or Thread.
I JAMES EDWARD BROADBENT of Stalybridge in the County of Chester,
Manager, 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 principally to machines for winding yarn on bobbins or

page_text: tubes usually called quick traverse winding frames, and the object of the invention
is to simplify the motion for actuating the traverse or slide bar and at the same
time render it capable of being driven at a very high speed, and also capable of
adjustment to vary the length of the traverse.
In order that this invention may be clearly understood I have annexed hereto
two sheets of drawings illustrative thereof and have marked the same with figures
and letters of reference corresponding with those in the following description.
On Sheet 1 Fig. 1 is a front elevation of part of a machine for winding yarn,
with my improvements applied thereto.
Fig. 2 is a face view and Fig. 3 a plan of my improved traverse motion detached
and drawn to a larger scale.
Fig. 4 shews a detached part hereafter referred to.
On Sheet 2 Figs. 5, 6, 7, 8, 9, 10, 11, and 12 illustrate modifications hereafter
more particularly described.
The invention consists in connecting the traverse or slide bar a by a link b
to a crank pin c carried by a sliding block d to which motion is given by the
following means. The block d is mounted so as to be capable of sliding in or upon
a lever e or its equivalent, fixed upon a cross shaft fat one end of the frame and on
a level with the said traverse or slide bar a. The block dis also provided with a
bowl g running in a grooved cam or plate h fixed to the frame and parallel with the
orbit or plane of rotation of the said block d. The groove of this cam is so curved
around the centre of the shaft f above named that it regulates the speed of the
throw or traverse of the slide bar a so as to compensate for the slow motion of the
crank pin in passing the "dead centres" and make a sharp return at either end of
the traverse, thus effecting by a simple modification of the crank motion what is
usually done by a lever and a heart or circular cam or other more complicated
device.
The crank pin c by which the link b is connected to the block dis or may be
adjustable in a groove di in the latter as shown detached at Figs. 8 and 9 or
otherwise so that although the traverse of the bowl g in its groove is constant
that of the crank pin c may be increased or decreased according to the length
of bobbin required.
In some cases the block slides upon its levere which is in the form of a rod
see Figs. 1, 2, 3 4 and detached views Figs. 8 and 9 and it is prevented from
turning thereon by passing the crank pin c through a small block c* shewn detached
at Fig. 4 sliding in a radial groove in a second lever e¹ fixed on the aforesaid
shaft and coinciding with the direction of the first lever e.
Or the lever e may be in the form of a block with two rods e e, see Figs. 5
and 6, Sheet 2, upon which the block d, shewn detached at Fig. 7 slides. In this
case the second lever e¹ is dispensed with.
Or the levere may be made in the form of a slotted or grooved box either
square (as shewn at Figs. 10 and 11) or cylindrical as shewn at Fig. 12 and in
these cases also the second lever el is dispensed with, and in the latter case blocks c*
are employed in the slots to keep the block d from turning in the lever e.
It will be evident without further illustration that the shaft f may be vertical,
and the cam plate h set in a horizontal plane instead of being vertical as shewn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the traverse or slide bar of a grooved or slotted crank
lever, carrying a block connected by a pin and link to the said slide bar, and also
carrying a bowl running in a groove in a fixed cam so shaped as to compensate
for the slow motion of the crank pin as it passes the "dead centres," substantially
as herein before described and illustrated by the drawings annexed.
2. The combination with the traverse or slide bar of a grooved or slotted crank
lever, carrying a block connected by a pin and link to the said slide bar, and also

page_text: carrying a bowl running in a groove in a fixed cam, so shaped as to compensate for
the slow motion of the crank pin, the centre of the latter being adjustable with
regard to that of the bowl to vary the length of traverse, substantially as herein-
before described and illustrated by the annexed drawings.
