Improvements in or applicable to Machines for Winding Yarn
or Thread.
I ROBERT BROADBENT of Phoenix Iron Works Stalybridge in the County of
Chester, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to what are known as "drum winding frames" employed
chiefly for winding hosiery yarn and the objects of the invention are first to enable
the same machine to be adapted for winding either conical or cylindrical bobbins
without removing the spindle carriers from the frame, and secondly to afford a
ready and efficient means for adjusting the tension of the threads on such machines.
In winding machines or frames of this class the drums are driven and the yarn is
wound upon a spindle which is supported by a carrier so that the spindle rests by
its own weight upon the surface of the drum and is driven by friction of contact
therewith.
The spindle carrier consists usually of an open frame with two arms hanging by
two bosses on a rod at the back of the drums."
Some of these machines or frames are made with cylindrical driving drums and
some with conical driving drums, and it is a peculiar distinctive feature of my
invention that it can be applied to winding machines or frames having either
cylindrical or conical driving drums.
When the frame is designed to wind conical bobbins, a conical spindle is used,
and the arms of the carrier are made at different angles, or one higher than the
other, so that the lower side of the spindle may be in a horizontal plane corre-
sponding with the upper surface of the drum; and when it is designed to wind
cylindrical bobbins a cylindrical spindle is used and both of the arms of the carrier
are usually on the same level.
I am aware that attempts have been made to construct a convertible carrier by
making one of the arms (or a portion thereof) adjustable with regard to the other,
so that the same machine might be used for winding both cylindrical and conical
bobbins, but inasmuch as when the two arms are thus adjustable the holes in which
the two ends or axles of the spindles work could not be coincident in both positions,
and hence the spindles could not run true in both positions but would have too
much friction in one position and be loose in the other.
My invention is intended to remedy this defect and to enable the two arms of
the carrier always to remain in exactly the same relation to each other and at the
same time to allow of the change of position with regard to the rod upon which
they are hung, which is necessary to allow them to be adapted to work with either
conical or cylindrical spindles, and with conical or cylindrical driving drums.
For this purpose I make the spindle carriage in two parts, the one consisting of
the two bosses and a straight bar uniting the two, and the other of the two arms
and a corresponding straight bar uniting them.
These bars are surfaced so that they fit together and they are hinged together at
or near one end by a bolt pin or rivet.
Near the centre one of them has a round hole and the other a corresponding
curved slot through which passes the shank of a tightening screw so that the
position of one bar can be altered with regard to the other so as to obtain the
requisite adjustment, and fixed in that position by tightening the screw, whilst
the arms will still remain always in precisely the same relation to each other, and
hence the spindles will always run true.

page_text: For regulating the tension on the threads I employ a rail of wood or other
material having a rounded surface and covered with felt flannel or other suitable
substance. This rail is carried by short levers or arms mounted on a round bar or
spindle fixed to the frame. When these levers or arms are in the perpendicular
position the rail is approximately horizontal and the threads pass over the whole
surface giving in that case the maximum of friction and tension but by adjusting or
fixing the arms in a diagonal or nearer to a horizontal position the amount of surface
with which the threads come into frictional contact will be diminished and the
tension proportionately decreased.

Improvements in or applicable to Machines for Winding Yarn
or Thread.
I ROBERT BROADBENT of Phoenix Iron Works Stalybridge in the County of
Chester 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 :-
This invention relates to what are known as "drum winding-frames" employed
chiefly for winding hosiery yarn, and the objects of the invention are, first, to enable
the same machine to be adapted for winding either conical or cylindrical bobbins
without removing the spindle carriers from the frame, and secondly to afford a
ready and efficient means for adjusting the tension of the threads on such machines.
In winding machines or frames of this class the drums are driven and the yarn is
wound upon a spindle which is supported by a carrier so that the spindle rests by
its own weight upon the surface of the drum and is driven by friction of contact
therewith.
The spindle-carrier consists usually of an open frame with two arms hanging by
two bosses on a rod mounted at the back of the drums and in a position parallel to
the axis of the same.
Some of these machines or frames are made with cylindrical driving drums, and
some with conical driving drums, and it is a peculiar distinctive feature of my
invention that it can be applied to winding machines or frames having either
cylindrical or conical driving drums.
When the frame is designed to wind conical bobbins a conical spindle is used,
and the arms of the carrier are made at different angles, or one higher than the
other, so that the lower side of the spindle may be in.a horizontal plane corre-
sponding with the upper surface of the drum, whether the latter be cylindrical or
conical; and when it is designed to wind cylindrical bobbins a cylindrical spindle
is used, and both the arms of the carrier are usually on the same level.
I am aware that attempts have been inade to construct a convertible carrier by
making one of the arms (or a portion thereof) adjustable with regard to the other,
so that the same machine might be used for winding both cylindrical and conical
bobbins but inasmuch as when the two arms are thus adjustable the holes in which
the two ends or axles of the spindles work could not be coincident in both positions,
and hence the spindles could not run true in both positions, but would have too
much friction in one position and be loose in the other, and when one arm is thus
adjustable upon the carrier the distance between the bearings of the spindles
varies, necessitating the use of spindles of different lengths when making the
change.
I am also aware that it has been proposed to attain the same object by providing
the spindle carrier with two independent pivots one at right angles to the other

page_text: so as obtain a compound adjustment but this arrangement was complicated and
costly and otherwise objectionable and was also inapplicable to some forms or
construction of winding frames.
My invention is intended to remedy these defects at the same time that it'
enables the two arms of the carrier always to remain in exactly the same relation
to each other and also to allow with regard to the rod or bar upon which they are
hung which is necessary to allow them to be adapted to work with either conical
or cylindrical spindles.
The nature of my sa'd invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheets of drawings and the following explanation thereof.
Fig. 1 is a side elevation Fig. 2 a face view and Fig. 3 a plan of so much of a
drum winding machine as is necessary to illustrate the construction and application
of my invention thereto, and Figs. 3 4 and 5 illustrates a modification thereof
wherein the carriers instead of swinging upon a long rod or shaft at the back of
the drums swing each upon a short stud carried by a bracket bolted to a long bar
extending lengthwise of the frame. (Figs. 1 and 2) being part of the frame of
the winding machine and two of the conical driving drums.
a
For the purposes of my invention I make the spindle carrier in two parts, one
consisting of the two bosses c and c¹ upon which the carrier hangs and a straight
bar uniting the two, and the other of the two arms d and d' at the ends of
which are the bearings for the spindles e, and a corresponding straight bar d"
uniting the said arms d and d¹ together.
These bars c and d are surfaced so that they fit together and they are hinged
together at or near one end by a bolt for by a pin or rivet.
Near the centre one of them has a round hole and the other a corresponding
curved slot through which passes the shank of a tightening screw so that the
position of the one bar d" can be altered with regard to the other cl so as to
obtain the requisite adjustment, and fixed in that position by tightening the
screw whilst the arms d and d¹ will still remain always in precisely the same
relation to each other, and hence the spindles e will always run true and need not
vary in length.
In the modification illustrated by Figs. 4 5 and 6 the carrier is made all in one
piece consisting of a straight bar two bosses c and c' and two arms d and d¹.
The bosses instead of hanging on a long rod or shaft as in Figs. 1 2 and 3
swing on short axis or pivots i carried by fixed brackets k which are bolted to a
long fixed rail extending longitudinally of the machine.
These brackets k are made with one hole at or near one end and two holes at
or near the centre so that they can either be bolted in a position parallel to the
rail (as shown at the right hand of Fig. 5) to work with cylindrical spindles or
bolted in the diagonal position (as shewn at the left hand of the same fig.) to
operate with conical spindles.
In both cases m is the ordinary friction spring acting against the rod or axis
upon which the carrier hangs.
For regulating the tension on the threads I employ a rail n (see Figs. 12 and 3)
of wood or other material having a rounded surface and covered with felt, flannel,
or other suitable substance.
This rail n is carried by short levers or arms o mounted on a round bar or
spindle p fixed to the frame a. When these levers or arms o are in the perpen-
dicular position (as drawn in full lines at Fig. 1) the rail is approximately
horizontal, and the threads pass over the whole surface giving in that case the
maximum of friction and tension, but by adjusting or fixing the arms o in a
diagonal or nearer to a horizontal position (as drawn in dotted lines at Fig. 1
and shown at the left hand on Fig. 2) then the amount of surface with which the
threads come into contact will be considerably diminished and the tension be
proportionately decreased.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
First. In a drum winding machine of the class herein before referred to, the
combination with a conical or cylindrical driving drum of a spindle carrier formed
of two surfaced plates one carrying the two bosses on which the carrier swings
upon a long rod or shaft parallel to the axis of the driving drums and the other
carrying the two arms which form the bearings for the spindle, the two plates
being fitted with means whereby they may be adjusted and fixed parallel or
coincident with each other, or one at a slight angle to the other substantially as
and for the purposes hereinbefore described.
Secondly. I claim in a drum winding machine of the class hereinbefore
referred to the combination with a conical or cylindrical driving drum of a single
spindle carrier in the ordinary form hanging by bosses onto a short axle or stud,
the said axle or stud being carried by a bracket bolted to a long fixed rail
attached to the frame of the machine, the said brackets being fitted with means
whereby they may be adjusted and fixed parallel or coincident with the said fixed
rail or at a slight angle thereto substantially as and for the purposes herein before
described, and
Thirdly. I claim the combination with a drum winding frame of the class
hereinbefore referred to, of a tension device consisting of a rail of wood or other
material having a rounded surface covered with felt or other suitable substance,
mounted upon short arms capable of moving about a rod or axis and fitted with
means for setting and fixing the arms in various positions so as to increase or
diminish the extent of surface over which the threads pass substantially as and for
the purposes hereinbefore described.
