Improvements in Machines for Winding or Spooling
Yarn or Thread.
I JOHN WILLMARTH FOSTER of Westfield, County of Hampden, in the State
of Massachusetts one of the United States of America, Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The Specification of Letters Patent No. 6765, dated April 20, 1891, shows and
describes apparatus for winding masses of thread or yarn, both upon a quill, and
upon a cone, the journals of the roll holding the quill and also of the roll holding
the cone, having co-operating with them a vertically sliding weighted yoke.
In the said Patent the shell rolls for rotating the spools or cones upon which the
yarns or filamentous material is wound are supposed to be arranged side by side and
parallel each to the other, but herein I intend to have the shell rolls arranged end
to end, or substantially so.
In my efforts to better adapt winding or spooling machinery, preferably such as
represented in said Patent, to holding and controlling the journals carrying the
quill or a cone upon which the yarn is being wound, so that the mass of yarn shall
be kept down properly upon the winding roll or device interposed between the
quill or cone on the one side and the shell roll on the other side, I have provided a
yoke of peculiar construction said yoke being so made as to support and carry the
said journals so that by lifting the yoke the journals will be lifted and the spool or
cone be elevated out of contact with relation to the driving roll of whatever form,
such as provided for in said Patent.
This yoke is provided with a handle in order that it may be readily elevated, a
friction device being employed to prevent the too free rising of the yoke during
the winding operation. The friction device, for the best results, will have one arm
or part adjustable with relation to the other arm or part, and preferably one part
will be made as a spring so as to regulate the friction.
parallel or substantially
The yoke referred to is mounted upon a pivot which
so to the axis of rotation of the driving roll referred to, so that the free end of the
yoke having the bearings to support the journals used to sustain either the quill or
the cone may rise and fall, and also the said yoke will have a suitable swivel joint
between the bearings and the pivot referred to, so that the part of the yoke
containing the bearings referred to may tip about a pivot or center substantially at
right angles to the center of rotation of the driving roll, adjustment of the portion
of the yoke containing the bearings as last referred to, enabling either a quill or a
cone to be readily supported by the yoke, and yet be presented properly with
relation to the driving roll.
One part of this invention consists in the use in a winding or spooling machine,
of a shell roll; a driving roll resting thereon and acting on and rotating a quill or
cone upon which is to be wound filamentous strands; and a yoke having a pivot not

page_text: only substantially parallel with the center of rotation of the driving roll but also a
pivot substantially at right angles to the centre of rotation of the driving roll, as
will be described.
Also in the use in a winding or spooling machine, of a yoke provided with
bearings adapted to not only rise and fall about a horizontal pivot parallel with the
axis of rotation of the driving roll but also to rock or tip at right angles to the axis
of rotation of the said driving roll; of a friction device co-operating with said yoke,
to operate, substantially as will be described.
Fig. 1, in front elevation, represents a sufficient portion of a spooling machine
containing my improvements, to enable my present invention to be understood.
Fig. 2, is a view taken to the right of the dotted line a Fig. 1.
Fig. 3, is a top or plan view of the yoke alone.
Fig. 4, a front elevation of the friction device and yoke guide; and
Fig. 5, a front end view of the yoke shown as supporting a cone, instead of a quill
or spool or bobbin.
Referring to the drawings, let it be supposed that the shaft e¹ is extended from
end to end of a spooling machine, and that it has on it a series of sets of disks e,
which receive over them loosely a series of hollow shell rolls, the latter hanging
by their weight upon the disks, and in such condition being rotated thereby, the
shell rolls having suitable crossing or endless grooves ' to receive a stud or pin 1
projecting from a traverse guide h³ provided with an eye to receive the thread or
filamentous material which is to be wound, the said shell roll acting to reciprocate
the said traverse guide upon suitable guide rods 12 held at their ends in suitable
stands a erected on a top plate or table A².
Resting upon the shell roll is a driving roll h* having its journals laid loosely in
a bearing supported by the stands a.
The parts so far described and referred to by letter are substantially the same as
in the Specification of the Patent cited, as to their operation, and in practice the
shaft may be rotated in any usual, or suitable manner adapted to spooling
machines. The shell roll will have working with it a brake-shoe, or lifting
device m, substantially as provided for in the Specification of the said former
Patent, which when the mass of yarn is of proper diameter, or which when the
thread breaks, will cause the shell roll to be lifted from contact with the disks, thus
immediately stopping the rotation of the shell roll and the winding operation.
As to the driving roll, designated by the letter *, it, when a quill is to be wound
so as to make a cylindrical mass of thread or filamentous material, will preferably
be cylindrical in form, and the periphery of the said driving roll for that work may
be in one single piece, but when a cone or conical mass of thread or filamentous
material is to be wound, then the driver roll will be of the form provided for in
Fig. 9 of the Specification of the said former Patent, wherein the driving roll is
shewn and described as made up of a series of loose rolls or sections so as to avoid
undue friction upon the yarn mass which varies in diameter and consequent surface
speed from end to end.
Erected upon the table A' is a stand n which supports a pivot n' which is located
parallel, or substantially so to the axis of rotation of the driving roll *.
The yoke referred to is composed of a part m* having arms m', m', provided
with suitable bearings m², the part m* having a rearwardly extended portion m³,
which is pivoted, jointed or articulated with relation to the part m' of the yoke so
that the part m* may tip or turn on or with relation to the part m' about a pivot
substantially at right angles to the center of rotation of the driving roll.
In this present instance of this invention, the articulation referred to has been
effected by a projection m³, shown by dotted lines, of the part m³, entering a hole or
longitudinal central opening in the part m', a screw m co-operating with the
extension or pivot m retaining the portion m* having the bearings m², in proper
position with relation to the part m³ of the yoke, which is free to rise vertically
about the horizontal pivot n' referred to.
When a quill is to be wound with a cylindrical mass of thread, either a paper or

page_text: other quill of any usual or suitable form is provided in usual manner with journals p
which are mounted in the bearings m², and the part m* of the yoke is so adjusted
with relation to the part m' that the centre of rotation of the quill and its journals p
will be substantially parallel to the centre of rotation not only of the driving roll h*,
but also of the shaft e¹.
But when a cone, or conical mass of thread or filamentous material is to be
wound, then a cone substantially such as provided for in Fig. 2 of said former
Specification of Patent, or as herein shown in Fig. 5, will have its journals mounted
in the bearings m² of the yoke, and the screw m will be loosened so as to let the
portion m* of the yoke be tipped about a pivotal point or center substantially at
right angles to the center of rotation of the driving roll so that the cone can take
proper bearing upon the driving roll of whatever form.
In practice, the portion m³ of the yoke is placed between the jaws r, r, of a
friction device suitable attached to the table plate A² by suitable screws »², one of
the arms being preferably of spring metal and being adjustably attached to the
block or stand to which is connected the arm r so that by or through a suitable
nut or screw the arm may be adjusted toward or from the arm r.
This friction device by pinching the portion m³ of the yoke acts as and performs
the duty of the weight provided for in the last mentioned Patent and also obviates
jarring due to the rapid motion of some of the parts, and the friction of the friction
device upon the yoke has to be overcome as the mass of thread is being wound, and
the yoke rises.
By the adjusting means the friction can be varied as desired.
.
The yoke is provided with a handlet which may be engaged by hand whenever
it is desired to quickly lift the bearing end of the yoke to elevate the mass of wound
thread or filamentous material from the driving roll, or for any other purpose in
the operation of the parts.
As herein provided for the rock shaft 7 having the arm 18 on which is pivoted
at 19 the brake shoe m to contact with and lift the shell roll h, as provided for in
said Patent, has an arm m² connected by chain and arm or otherwise with
the yoke.
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 use in a winding or spooling machine, of a shell roll; a driving roll
resting thereon and acting on and rotating a quill or cone upon which is to be
wound filamentous strands; and a yoke having a pivot not only substantially
parallel with the center of rotation of the driving roll but also a pivot sub-
stantially at right angles to the centre of rotation of the driving roll, substantially as
described.
2. The use in a winding or spooling machine, of a yoke provided with bearings
adapted to not only rise and fall about a horizontal pivot parallel with the axis of
rotation of the driving roll but also to rock or tip at right angles to the axis of
rotation of the said driving roll; of a friction device co-operating with said yoke,
to operate, substantially as described.
3. The general arrangement or combination of parts of a winding or spooling
machine co-operating as and for the purposes hereinbefore set forth.
