PROVISIONAL SPECIFICATION.
Improvements in or Applicable to Machinery for Doubling and
Winding Fibrous Yarns or Threads.
I JAMES HORROCKS, of the firm of John Horrocks & Son, of Parker Street Mills,
Ashley Lane, Manchester, in the County of Lancaster, Machine Makers, do hereby
declare the nature of the said invention to be follows:-
My invention relates to, and consists in, a combination and arrangement or in
combinations and arrangements of mechanism which are based upon that modification
for doubling and winding described in the specification of Letters Patent granted to
John Horrocks and myself Numbered 3132 A.D. 1881, and illustrated on the right hand
side of figs. 1 and 2 of the drawings, and are also partly based upon that arrange-
ment for winding and doubling shown by sheet 1 of the drawings and described in
the specification of Letters Patent also granted to John Horrocks and myself
Numbered 4500 A.D. 1882, and my improvements though applicable to winding
yarns or thread in the ordinary way upon bobbins with ends are more especially
designed and intended for doubling and winding yarns or threads upon bobbins or
spools without ends, the winding required by such bobbins being termed "
winding," for which purpose the traverse of the threads to and fro have to be very
quick; and to produce a square ended bobbin the thread guide has to be arranged
to deliver the threads as close as possible to the point of contact between the bobbin
and winding drum, and it is therefore necessary that the bobbin should be held and
kept against the drum when winding, both when empty and full, in the same relative
position to the thread guide, or as near to that position as possible.
My improved combination consists as follows.
cross
There is an oscillating plate carrying detector wires and a rotary shaft for acting
thereon.
The oscillating plate has a finger which holds the prop jointed to one end of a
beam lever, (which I will hereinafter term the prop lever) having its fulcrum on
a bracket on the framing.

page_text: To projections from the front part of the prop lever, the bobbin frame lever is
jointed, the joint or fulcrum being in such position in relation to the winding drum
that the bobbin will move to and from the winding drum in nearly a horizontal
direction.
The two arms of the bobbin frame are curved towards the winding drum so that
the weight of the frame thus added on one side of its fulcrum will bring and press
the bobbin against the winding drum.
The rear end of the prop lever extends backwards, and upon it an arm rests,
(hereinafter termed the brake arm) which brake arm has its fulcrum on a bracket on
the framing. The free end of the brake arm comes forward and to it a lever is jointed
(hereinafter termed the brake lever) the upper end of which is shaped to come against
the bobbin as a brake surface when the winding is to be arrested, the lower end of
the brake lever is curved and passes through a hole in the prop lever, the edge of
which hole gives oscillation to the brake lever when the prop lever rises and falls,
that is, to bring (the brake lever) against the bobbin when the prop lever falls, and
move the brake lever clear of the bobbin when the prop lever rises and the bobbin is
winding.
When the prop lever descends by the action of the rotary shaft and oscillating
plate, the bobbin frame is allowed to fall and bring the bobbin away from the drum
and at the same time the brake arm lifts the brake lever against the surface of the
bobbin and arrests its momentum and moves the bobbin forward so that the thread
comes out of the thread guide.
There is an arm hinged to the prop lever which has a projection that catches upon
and holds the bobbin frame when moved to bring the bobbin clear of the brake lever
at the time the threads are to be pieced.
The threads to be doubled and wound pass over the ordinary overhead pulley
before going to the thread guide and bobbin."

I JAMES HORROCKS, of the firm of John Horrocks & Son of Parker Street Mills,
Ashley Lano, Manchester, in the County of Lancaster, Machine Maker, 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 and consists in a combination and arrangement or in
combinations and arrangements of mechanism which are based upon that modification
for doubling and winding described in the specification of Letters Patent granted to
John Horrocks and myself Numbered 3132 A.D. 1881, and illustrated on the right
hand side of figs. 1 and 2 of the drawings and are also partly based upon that
arrangement for winding and doubling shown by sheet 1 of the drawings and described
in the specification of Letters Patent also granted to John Horrocks and myself
Numbered 4500 A.D. 1882 and my improvements though applicable to winding yarns
or thread in the ordinary way upon bobbins with ends are more especially designed
and intended for doubling and winding yarns or threads upon bobbins or spools
without ends, the winding required by such bobbins being termed "cross winding
for which purpose the traverse of the threads to and fro have to be very quick; and
to produce a square ended bobbin the thread guide has to be arranged to deliver the
threads as close as possible to the point of contact between the bobbin and winding
drum, and it is therefore necessary that the bobbin should be held and kept against
the drum when winding, both when empty and full in the same relative position to the
thread guide, or as near to that position as possible.
My improved combination consists as follows:
""
There is an oscillating plate carrying detector wires and a rotary shaft for acting
thereon.
The oscillating plate has a finger which holds the prop jointed to one end of a
beam lever (which I will hereinafter term the prop lever) having its fulcrum on a
bracket on the framing.
To projections from the front part of the prop lever, the bobbin frame lever is
jointed, the joint or fulcrum being in such position in relation to the winding drum
that the bobbin will move to and from the winding drum in nearly a horizontal
direction.
The two arms of the bobbin frame are curved towards the winding drum so that
the weight of the frame thus added on one side of its fulcrum will bring and press
the bobbin against the winding drum.
The rear end of the prop lever extends backwards, and upon it an arm rests
(hereinafter termed the brake arm) which brake arm has its fulcrum on a bracket on
the framing.

page_text: The free end of the brake arm comes forward and to it a lever is jointed (hereinafter
termed the brake lever) the upper end of which is shaped to come against the bobbin
as a brake surface when the winding is to be arrested, the lower end of the brake
lover is curved and passes through a hole in the prop lever, the edge of which hole
gives oscillation to the brake lever when the prop lever rises and falls, that is, to bring
the brake lever against the bobbin when the prop lever falls, and move the brake
lever clear of the Bobbin when the prop lever rises and the bobbin is winding.
When the prop lever descends by the action of the rotary shaft and oscillating plate
the bobbin frame is allowed to fall and bring the bobbin away from the drum and at
the same time the brake arm lifts the brake lever against the surface of the bobbin
and arrests its momentum and moves the bobbin forward so that the thread comes out
of the thread guide.
There is an arm hinged to the prop lover which has a projection that catches upon
and holds the bobbin framo when moved to bring the bobbin clear of the brake lever
at the time the threads are to be pieced.
The threads to be doubled and wound pass over the ordinary over-head pulley before
going to the thread guide and bobbin.
Fig. 1 is a plan view with part of the drum shown broken away illustrating the
parts of one head according to my invention, and fig. 2 is an end sectional elevation
of the parts shown in fig. I which in both views are shown in the position the parts
occupy when winding.
Figs. 3 and 4 are similar views to fig. 2 except that fig. 3 shows the parts in the
position they occupy when the winding is stopped by reason of a thread having broken
or coming to an end, and fig. 4 shows the parts in the same position as in fig. 3
except that the bobbin frame has been moved into the position for finding and piecing
tho thread or threads.
-
The oscillating plate e carrying the detector wires is the same or is similar to that
shown by figs. 1, 2 and 3 of the specification of the said Letters Patent No. 4500 - 1882
and the detector wires are operated when a thread breaks by a rotary shaft as in the
last named specification.
=
The threads being wound pass to the detector wires and from them to one overhead
pulley in place of two (described in the said specification No. 4500 1882) to the
barrel or bobbin f as described in the specification of the said Letters Patent
No. 4500 = 1882 and the thread guide for distributing the thread upon the barrel
or bobbin is or may also be arranged as described in the specification of the said
Letters Patent No. 4500 = 1882.
a is the beam for carrying the pivots c¹ of the oscillating plate, e² the finger from
the plate c for sustaining the prop when the bobbin is to press against the drum
when winding.
a is the beam for carrying the other parts of each head and to this beam a* a
bracket dis secured which carries the axis or fulcrum e² of a lever frame e. The
front end of this lever frame e (herein before termed the prop lever) has the prop g
jointed to it at ex, and this prop when in the position shown in fig. 2 sustains the
weight of that end of the prop lever frame e and the parts carried by it.
To two downward projections e² from the prop lever frame e, the bobbin lever
frame is jointed on a fulcrum at f, this bobbin frame being curved, as shown, under
the drum on the shaft. so that its weight on that side of its fulcrum or joint"
acts to press the bobbin carried by it against the drum surface of the drum-The
upper end of the frame, is made with slots to receive the ends of the spindle upon
which the barrel or bobbin rotates.
To a projection or arm d from the bracket d the fulcrum of a leverk (hereinbefore
termed the brake arm) is mounted to the free end of which a brake lever is jointed
at the upper end of this lever forms the brake surface which rises and enters
between the bebbin and the drum and pushes it into the position shown in fig. 3
when a thread breaks or comes to an end.
The lower end of the brake lever is curved as shown and passes through a slot or
hole in the prop lever frame e as shown.

page_text: When the prop lever frame e descends a projection from it, upon which the
brake arm lever & rests, lifts the latter to the position shown in fig. 3 and the front
edge of the slot or hole in the prop lever frame e pushes the upper end of the brako
lever forward as shown in fig. 3 to hold the bobbin clear away from the surface of
the drum h¹.
There is a latch m jointed to the prop lever frame e at m' and when the bobbin
frame is moved forward into the position shown in fig. 4 a projection fx from one
side of the frame catches upon the hook of the latch m which holds the bobbin framo
in the position shown in fig. 4.
The end of the latch m rests upon the beam ax at all times.
By lifting the handle e' upon the prop lever frame e when the winding is to begin
all the parts are brought into the positions shown in fig. 2.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is,
1. The combination of the mechanism illustrated by figs. 1 and 2 substantially as
and for the purpose hereinbefore described.
2. The combination of an oscillating detector-plate (c) prop (g) prop lever frame (e)
brake arm lever (k) carrying brake lever () and the bobbin frame lever (f)
substantially as hereinbefore described and illustrated by the drawings.
