We JAMES WHALEY SHEPHERD and WILLIAM AYRTON of the firm of Shepherd and
Ayrton of the Gorebrook Iron Works Longsight Manchester in the County of
Lancaster Engineers and Machinists and RALPH CLEGG of Wellington Place
Longsight aforesaid in the employment of the said firm Mechanical Draughtsman 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:-
Our invention consists in arrangements of apparatus to be used in conjunction with
the machines for winding yarns or threads for which Letters Patent No. 48 dated
January 6th 1870 were granted to William Weild.
In order that our invention may be readily understood we shall as far as possible
apply to the various parts to be hereinafter mentioned names similar to those employed
in reference to corresponding parts in the Specification of the Letters Patent before
referred to.
In the accompanying drawings Figs. 1, 2 and 3 show so much of a machine for
winding yarn or thread on to bobbins, spools or other similar bodies as is requisite to
illustrate our invention-Wo shall hereinafter refer to the bobbin, spool or other similar
body upon which the yarn or thread is to be wound as the "bobbin "-The first part
of our invention refers to arrangements of apparatus whereby we are enabled to
employ one "shaper plate" for governing the "winding on" of the yarn or thread
on to bobbins of any width between the heads and having heads formed by discs or
with ends of various angles relative to the cylindrical portions of such bobbins.
In the accompanying drawings in which Fig. 1 is a plan, Fig. 2 a side view and
Fig. 3 an end view, a is a bar capable of being moved longitudinally and laterally in
recesses formed in brackets bb formed on a headstock 6' secured to the framework c
of the machine-We shall hereinafter refer to the bar a as the supplementary shaper
bar.-d is a frame mounted upon a pin or stud e the ends of which pass into bearings
formed in brackets / secured to the headstock 6-The arms d¹ which project from the
frame d are provided with jaws d' which embrace the supplementary shaper bar a
which is capable of being slidden longitudinally in the said jaws d².

page_text: .
In the brackets b b are formed slots in which slots and capable of being slidden
therein is a bar g-The bar g is retained in the slots aforesaid by means of caps b
secured by set screws to the brackets bb-Upon the shaper-cam-shaft is the shaper-
cam which in machines as ordinarily constructed moves the shaper in one direction
such shaper being moved in the opposite direction by means of a spring but which in
a machine constructed according to our invention causes the shaper bar g to traverse
in the direction indicated by the arrow A in a manner similar to that in which the
shaper slide is moved in machines as heretofore constructed. We shall hereinafter
refer to the bar g as the "shaper slide "-The "shaper slide" g controls the action of
the "clutch box" as is usual in machines as ordinarily constructed-Formed upon
the shaper slide 9 is a projecting part g¹ and fixed upon the said shaper slide g is a
stud upon which stud k and capable of being turned thereon is a bracket / in
which is formed a curved slot m-Secured by one end to the projecting part g¹ is a
bolt n provided with a nut n―The said bolt n passes through the curved slot m-
Formed upon the headstock is an arm o-Secured to one end of the arm o is a
stud p mounted upon which and capable of being turned thereon is a bell-crank-
lever q―The end q¹ of the bell-crank-lever q is provided with a stud q³ upon which is
a bowl which rests against the face of a rib formed on the bracket -In the
end q3 of the bell-crank-lever q is formed a slot q* in which is a stud 95 one end of
which projects so as to extend across the end of the supplementary shaper bar a-The
stud q is capable of being moved along the slot q by means of the set screw q° and
may be secured in any desired position by means of the nut q.
We find a shaper of the following proportions to be a useful one, but a shaper r
of other proportions may be employed-The shaper is tapered from B to C in the
proportion of one inch in three quarters of an inch, hence the graduations D on the
bell-crank-lever 7 must be three quarters distance to make a difference of one inch
and the three quarters of an inch divided into sixteen parts to make a difference of
sixteenths of an inch in the shaper and so on.
We will assume that the bobbin upon which the yarn or thread is to be wound is
one inch and three quarters long at the top and one inch and a quarter long at the
bottom as indicated in the diagram Fig. 4-It is then necessary to set the stud q³ so
that it is opposite to the point E which indicates one inch and three quarters on the
graduations D-To set the shaper to the one "inch and a quarter" for the bottom
part of the bobbin we must find what we call the surplus of one inch and three
quarters after deducting the one "inch and a quarter" which gives half an inch-We
now find the point which indicates half an inch on the graduations F upon the
bracket 7 and after slackening the nut n¹ turn the bracket until the half inch mark
of the graduations F before mentioned coincides with the finger s secured to the
projecting part g―The bracket is then prevented from moving by the nut n¹ being
again tightened-When the yarn or thread is being wound upon the bobbin the shaper
slide g and the projecting part g' secured thereto are traversed by the cam ; in the
direction indicated by the arrow A--Such movement of the shaper slide g and pro-
jecting part g¹ will cause the rib 12 to act against the bowl upon the stud q2 and the
rib being inclined will turn the bell-crank-lever q on the stnd p in the direction
indicated by the arrow G-Such turning of the bell-crank-lever q will by means of
the stud 9 push the supplementary shaper bar a in the direction indicated by the
arrow H, the supplementary shaper bar a being moved more or less as the face
the projecting rib is placed more or less inclined to the direction of motion of the
shaper slide g.
of
Secured to a projecting part g¹ is a stud mounted upon which so as to be capable
of being turned thereon is a part t. Secured to the projecting part g' is a stud t
which projects through a curved slot g' formed in the part gl and is provided with a
nut In the part t is formed a groove or slot 2 in which and capable of being
slidden therein is a block u from which projects a stud a¹ which passes into a hole
formed in a projecting part d³ formed upon the frame d.
In those cases in which the two ends of the bobbin are not equally inclined to the
axis of the bobbin we after having set the bracket and stud q' in the positions

in the
necessitated by the dimensions of the top and bottom of the bobbin turn the part t
so as to place the groove or slot t2 at an angle to the direction of motion of the shaper
slide 9. The part t may be secured in any desired position upon the projecting part g¹
by means of the nut a screwed upon the stud -As the shaper slide
direction indicated by the arrow A the slot t² acting upon the block u which enters
into the slot and is provided with the stud u¹ which enters into a hole formed
in a projecting part d³ secured to the frame d, will cause the frame d to be turned
either in the direction indicated by the arrow or in the direction opposite to that
indicated by the said arrow J and cause the shaper to be moved in a like direction
while it is also being moved in the direction indicated by the arrow H the movement
of the shaper in the direction indicated by the arrow J or in the direction opposite
to that indicated by the arrow J or in the direction opposite to that indicated by the
arrow J compensating for the difference of the angles of the ends of the bobbin-By
placing the slot t² in a position more or loss inclined to the direction of the motion of
the shaper slide g the movement of the supplementary shaper bar a will be caused to
be more or less in the direction indicated by the arrow J or in the direction opposite
to that indicated by the arrow J-Such movement of the supplementary shaper bar a
will cause the yarn or thread to be evenly and regularly built upon a bobbin the ends
of which are of different angles.
We have only described one method of moving the supplementary shaper bar a in
the direction indicated by the arrow J or in the direction opposite to that indicated by
the arrow J but we do not confine ourselves to the arrangement herein before shown
and described as other arrangements of a "parallel motion " may be employed for
the purpose of moving the supplementary shaper bar a in the direction indicated by
the arrow J or in the direction opposite to that indicated by the arrow J.
A further part of our invention consists in arrangements of mechanism for keeping
at certain times to be hereinafter more particularly mentioned the "partial screw
nuts" out of gear with the "right hand" and "left hand" "threads" of the screw
shaft employed in the machines before referred to for traversing the " traverse
bar."
Secured to one of the brackets bare brackets mounted in which so as to be
capable of being rotated therein is a short shaft w-Fast upon the short shaft w is a
boss from which projects an arm ¹-Secured to the short shaft w is an arm y-
Projecting from the army is a weight y' which weight y' tends to turn the army,
shaft w and arm in the direction indicated by the arrow K-Secured upon the
'strap fork rod" is a collar 1 one end of which collar 1 is provided with an inclined
part 1-2 is the "oscillating tail piece" projecting from the "traverse bar" such
'oscillating tail piece" 2 during the winding of a spool being traversed across
alternately above and below the shaper r.
"
During such time as yarn or thread is being wound upon the bobbins or spools the
edge y of the yarn y rests against the circumference of the collar 1 and the arm c¹
is thereby held clear of the path of the "oscillating tail piece" 2.
When the bobbins or spools have become filled with yarn or thread and are required
to be replaced by empty bobbins or spools the "strap fork rod" will have to traverse
in the direction indicated by the arrow L and the collar 1 will then be carried clear
of the army which will then be turned by the weight y' until the arm y rests against
the "strap fork rod" z.
Such turning of the arm y causing the arm to pass into the path of the "oscillat-
ing tail piece" 2 so that the " oscillating tail piece" 2 after the shaper r has been
moved back will drop upon the top of the arm a¹ so as to be supported thereby and
hold the "partial screw nuts" in such position that they will both be clear of the
"right hand" and "left hand " "threads" of the screw shaft employed to distribute
the yarn or thread upon the surfaces of the bobbins or spools thereby enabling the
traverse bar 3 to be "shunted into the position requisite for winding the yarns
or threads upon fresh bobbins or spools-When the winding of fresh bobbins or
spools to be commenced the "strap fork rod" z will be moved in the direction
opposite to that indicated by the arrow L thereby causing the inclined part 1 to turn

page_text: the arm y, short shaft w and arm a' in the direction opposite to that indicated by the
arrow K.
The oscillating tail piece 2 being no longer supported by the arm I will descend
and one of the "partial screw nuts" will pass into gear with the threads of the
right hand screw ог "left hand screw" of the " screw shaft."

By means of the collar 1 provided with the inclined part 1° placed upon the "strap
fork rod z and the arm a¹ we are enabled with greater certainty than has hitherto
been possible to arrest the descent of the "oscillating tail piece" 2 and keep the
partial nuts" clear of the "right" and "left hand "screws until after the operation
of "shunting" the "traverse bar "3 has been completed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The hereinbefore described arrangement of apparatus by which we are enabled
to wind yarn or thread upon a bobbin or spool or other similar body of any form,
with but one shaper plate, which arrangement of apparatus consists in the shaper
slide g, supplementary shaper bar a, bell-crank-lever q, bracket 1, part t, and frame d,
all constructed arranged employed and operating in conjunction with each other for
the purposes and substantially in the manner hereinbefore described in reference to
and indicated in and by the drawings hereunto annexed.
"
2. The hereinbefore described arrangement of apparatus by which we are enabled
to arrest the descent of the "oscillating tail piece "2 so as to allow the operation of
shunting" to be performed with greater case and certainty than hitherto which
arrangement of apparatus consists in the arm x¹, arm y, weight y' and collar 1 all
constructed arranged employed and operating in conjunction with each other for the
purposes and substantially in the manner herein before described in reference to and
indicated in and by the drawings hereunto annexed.
