or other Materials.

facturer.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention
to be as follows:-
My invention is an improved winding machine particularly adapted for winding
yarn, my improvements relating more particularly to the means for mounting,
guiding and maintaining the proper pressure of the thread guide, certain details
of improvements also relating to the mounting and adjustment of the quill.
The general driving and reciprocating mechanisms, tension devices, etcetera,
may be of any desired kind.
1 employ a throw cam and instead of balancing the throw member of the thread
guide carrier or arm by means of oppositely projecting studs as has been done
heretofore, I mount a guide preferably consisting of a slot in one edge of a casing
or.housing of the machine, said guide engaging the stud or projection extending
from the throw member and working in the slot of the throw cam, between said
throw member and said cam.
My correspondent has discovered that this construction prevents a certain
vibration and unevenness which have existed in the previous construction, this
provision of the location of the slot between the throw cam and throw member
serving to give increased smoothness and nicety of movement.
A further important feature of my invention, and indeed the chief part thereof,
is in connection with the thread guide.
.:
This thread guide is made to swing away from the thread mass as the latter
builds up, and in order to maintain the required constant and uniform pressure
of the thread guide. upon the thread mass, there is provided a guide bar which
engages the thread guide arm intermediate the length of the latter, said guide
bar being carried eccentrically by means of a rotating hub mounted on a project-
ing sleeve carried concentrically of the throw member, this hub being held against
free rotation by means of a frictional collar from which a weight may .be
suspended or which may be pressed into engagement with said hub by means of
a spring in the manner of a friction brake.
In order that the thread guide arm may be free to swing, I may mount it
loosely on the end of the throw member by means of a very fine screw thread
connection, whereby the slight rotation thereof will not materially change the
relative longitudinal position of the parts, or I may provide a swivel joint in the
throw member itself so that a portion of it may turn with the thread guide arm.
A further feature of my invention resides in connecting the quill spindle with
the driving shaft by means of a universal, joint, said joint preferably consisting

page_text: of discs carried by the adjacent ends of the quill spindle and the driving shaft,
one of said discs carrying eccentrically a pin projecting therefrom, and the other
disc having a slot to receive said pin, the quill spindle being preferably supported
in a pivoted bracket, so that it can be adjusted as desired, the slot and pin con-
nection readily permitting of any such adjustment
This connection also facilitates changing the machine to wind a conical quill
or a parallel quill as desired, inasmuch as there are no gearing and no complicated
parts to require attention.

Improvements in and relating to Machinery for Winding Yarn
or other Materials.
A communication from abroad by ALFRED BRYANT MORSE, of 53, Leon Street,
Boston, in the State of Massachusetts, United States of America, Manu-
facturer.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, 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 to machines particularly adapted for winding yarn, the
novel features herein comprising especially the means for mounting and guiding
the thread guide, and for maintaining the proper pressure of the same upon the
thread mass, other novel features also relating to the mounting and adjustment
or the quill upon which the yarn or thread is wound.
Fig. 1 is a top or plan view of a sufficient portion of a winding machine to be
readily understood, with the present invention embodied therein.
Figs. 2 and 3 are front and left hand end elevations of the apparatus, re-
spectively.
Fig. 4 is a detail view of the quill spindle and adjacent parts, the connections
being shown in section substantially on the line 4-4, Fig. 1.
Fig. 5 shows in detail the thread guide support and adjacent parts, some of
which are shown in vertical longitudinal section.
Fig. 6 is a vertical cross sectional view taken on the line 6-6, Fig. 5.
Fig. 7 is a view similar to Fig. 6 showing a modification to be hereinafter
referred to.
Figs. 8 and 9 are longitudinal vertical sectional views of two means for
providing for swivel or swinging action of the thread guide as the yarn mass
builds up, and
i
Fig. 10 is a sectional detail on the line 10, Fig. 1.
The driving mechanism and throw cam arrangement herein illustrated are not
novel portions of this invention, only so much of such parts being herein shown
as to make the cooperation of the novel features therewith readily intelligible.
Power is derived from a pulley a coupled by a suitable clutch mechanism a¹,
and clutch lever a², to usual cone pulleys a, a, the latter operating a pinion a
in mesh with a gear 6 connected with and driving the throw cam a².
A belt shifter 8 is provided for shifting the belt carried by the cone
nulleva 34

page_text: The thread guide or guide button
is carried at the end of an arm b', provided
with a suitable rib or bracket 62, perforated to slide on a guide rods, supported
in special manner, presently to be described.
The arm has its hub b shrunk onto the end of a thin tube 65, supported by
internal ribs 66 on a bar or rod b.
Heretofore the throw member or tube 65 has been reciprocated by means of a
roll mounted thereon at one side and travelling in the throw cam, and a guide
pin travelling in a slot adjacent the rod 67, but on the opposite. side thereof from
the throw cam, and such arrangement is objectionable in that the reciprocation
of the thread guide is not as smooth and as uniform as must be in high speed
machines.
-
To overcome these objectionable features and to obtain a smooth and uniform
reciprocation of the thread guide, the direction or guide slot in the present in-
vention is located between the throw cam and the bar 67 and throw member 6,
and in the drawings a slot c is shown adjacent the rod 67, between it and the
throw cam a, and the stud 68 carried by the tube benters and is guided by this
slot, the free end of the stud entering the groove of the throw cam and serving
to reciprocate the thread guide.
This guide slot c is shown as made in one edge of a casing or housing c¹, which
forms a convenient frame for the adjacent portion of the machine and in which
various parts are journaled, but the guide slot may be provided for in any other
suitable manner, provided its location is maintained as hereinbefore set forth.
The quill spindle is herein made stationary, so far as its mounting or bearing
concerned, so that as the thread mass builds up the quill does not swing away
from the thread guide, but on the contrary the thread guide swings away from the
thread mass, and the mechanism by which this is accomplished constitutes one of.
the features of the present invention.
Viewing Figs. 5 and 6 in connection with Figs. 1 and 2, it will be seen that a
sleeved is provided within and projected from the hollow upper end of a stationary
bracket d¹, and on this projecting sleeve is mounted a hub d², supporting eccen-
trically the guide rod 63 referred to hereinbefore, so that as the thread mass builds.
up the thread guide can raise its guide rod 6, such movement of the latter being.
permitted by rotation of the hub 2 thereof on the supporting sleeve d.
As it is necessary for the proper winding of the thread or yarn that the thread
guide shall have a constant and considerable pressure on the thread mass, such
pressure is attained in this invention by means of an automatic frictional re-
sistance, which preferably takes the form of a frictional strap or collar d³, sur-
rounding the hub 2, and having attached to it by a rod a suitable weight d³,
so that all tendency of the thread guide to leave the thread mass is resisted, and
the pressure of the thread guide on the thread mass is kept uniform by the con-
stant frictional resistance of the strap or collar, on the hub d², due to the
weight d³.
Another practical embodiment of this frictional resistance is shown in Fig. 7,
as comprising a brake shoe or colla d having a stem supported in a hollow
5 post d, and normally held in constant frictional engagement with the hub d³ by
means of a spring, the tension of which is adjustable by means of a suitable
set screw 10.
In order that as the thread mass builds up, the thread guide may lift without
inconvenience to the tube b, I may make the latter in two sections, as shown
in Fig. 8, in which said sections are shown as provided with annular ribs 6, 610,
permanently secured thereto, the former of said ribs carrying a flange 612 with an
inturned lip 63, which embraces the rib 610, and constitutes a swivel coupling,
permitting the portion of the tube which carries the thread guide, to turn in-
dependently of the other portion, thus preventing any torsional strain upon the
5 tube 65.
Instead of the coupling mechanism shown in Fig. 8, I may mount the hub b
of the thread guide directly on the end of the tube b³, as shown in Fig. 9, where

page_text: it will be seen that I have threaded the parts together by extremely fine threads,
so that the slight angular movement occasioned by the thread guide will not
materially affect the relative longitudinal position of the parts.
Referring more particularly to Fig. 4, it will be seen that the quill spindle e,
for supporting any usual quill or bobbin e¹, and mounted in an adjustable
bracket e, pivotted atte³, is shown as arranged obliquely to support a conical quill
and in order that the spindle may be readily connected to and driven by the
drive shaft, I have coupled the same thereto by a universal joint, the adjacent
end of the drive shaft being provided with a disc f', preferably flanged, as
at f, and containing a pin f³ to enter a slot of a flange or disc et, rotating with
the spindle e.
Heretofore various connections have been provided between the quill spindle
and its drive shaft, such as a gear, but this is expensive and inconvenient and
other constructions devised have been cumbrous, whereas the connection herein
shown is simple and automatic in accommodating itself to its different positions,
the slot and pin connection conforming readily to changes in the angularity
between the drive shaft and quill spindle, and by this connection I am enabled
to adjust the angle of the spindle e to any minute degree desired, inasmuch as a
slight change in the angle thereof does not necessitate any change or adjustment
of the connection.
This form of universal joint is not the only one which may be used, though
for various reasons it is preferable, as for instance, it is usually more convenient
simply to remove the bracket e² and quill spindle when it is desired to change
from a cone to a parallel or tubular quill, and to replace them by another bracket
and spindle, and in such case it will be manifest that the slot and pin connection
facilitates such change or replacement of parts inasmuch as the slotted member
will pull off from the pin, or slides thereupon, as the case may be. The connection
provided for the rotation of the quill spindle will be rotated with equal facility
whether it be in alignment with its drive shaft or at an angle thereto.
I prefer to employ this connection, for the reason that it is extremely simple,
inexpensive, and easily kept in order.
In operation, as the thread guide is reciprocated, the tendency of the tube 65
and adjacent parts to vibrate or bind on the rod 67, is largely counteracted by
the position of the guide slot e, as already explained, and the running of the parts
is rendered extremely smooth and uniform.
As the thread mass builds up, the thread guide is permitted to swing by reason
of the swivel connection joining the two parts of the throw tube 65, and yet the
thread guide is constantly held down with the requisite pressure on the thread
mass by reason of the resistance offered by the guide rod 3, due to the constant
frictional pressure of the brake like device engaging the hub thereon.
While various other mechanisms have been suggested for maintaining the
proper pressure of the thread guide upon the thread mass, the present apparatus
possesses many advantages not found in present practice, as it requires no
particular skill in operation, but is absolutely automatic, and always uniform in
its action, irrespective of the size of the thread mass and the speed of the machine.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a winding machine, a quill spindle, a swinging thread guide, means to
reciprocate the said thread guide and to rotate said squill spindle, means permit-
ting said thread guide to swing as the thread mass builds up, and a frictional
resistance device for retarding said swinging movement uniformly.
2. In a winding machine, a quill spindle, a swinging thread guide, means to
