Improvements in Machines for Looping and Stitching Supporting
Tapes to Curtains or to Curtain Heading Bands or the like.
I, JOHN KYNASTON, of 70, Hope Street, Liverpool, in the County of Lancaster,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for looping and stitching the supporting
tapes used in heading curtains.
In the Specification to Letters Patent No. 17619 dated 17th September, 1894,
I have described a new and improved method of hanging curtains and my
present invention relates to a machine used for attaching and looping the
supporting tape used in connection with my said invention, the object being to
provide a machine adapted to loop and attach the supporting tape, at the one
operation, either to the curtains directly or to a supporting band which is stitched
to the curtains at the same time or afterwards.
Dealing in the first instance with the case in which the looped tape is stitched
to the curtains through a supporting band which at the same time is itself also
stitched to the curtain:-
I provide a sewing machine preferably of the Wheeler & Wilson type with a
double needle mechanism, adapted to stitch in two rows simultaneously, and I
modify the presser foot as follows: The foot is prolonged and has two guides,
one for the flat supporting tape which I will distinguish by referring to as the
supporting band, or briefly as the band, and one for the round tape which I will
term the looped tape, or briefly the tape, and I so arrange matters that as the
tape and the band are fed into the machine from bobbins and the sewing
mechanisms set into operation, the one needle attaches the tape and one edge of
the band to the curtain head by the one row of stitches and the other needle
attaches the other edge of the band to the curtain by the other row of stitches.
In order however to provide for the looping of the tape I provide a movable
guide placed between the entering guide and the needle which stitches the tape,
through which movable guide the tape is passed; as the tape and band are fed in,
and as the stitching proceeds, the movable guide withdraws, at regular intervals,
the tape from the line of stitching and so forms the loops, the stitching in the
meantime binding the band to the curtains; as the movable guide returns, the
looped tape again comes into the line of stitching, and for a portion of its length
is again secured to the band and to the curtains. Thus the tape is secured for
the whole of its length with the exception of the loops which are formed as
described.
When the looped tape has to be secured either directly to the curtain or to a
supporting band to be subsequently attached to the curtain, the action is similar
to that described, except that, of course, the second line of stitching is dispensed
with, and that no band need be used when the looped tape is attached to the
curtains directly.
The mechanism for operating the movable guide which I have found convenient

page_text: comprises a cam driven from one of the shafts of the machine by, say, worm
gear, and adapted to impart motion to the movable guide at the required inter-
vals; the mechanism may, of course, be adapted to vary the length of such
intervals and to vary the size of the loops and the guide may be operated from
above or below the table of the machine and may be a continuous guide as
described, or it may intermittently deflect the tape to produce the loops.

Improvements in Machines for Looping and Stitching Supporting
Tapes to Curtains or to Curtain Heading Bands or the like.
I, JOHN KYNASTON, of 70, Hope Street, Liverpool, in the County of Lancaster,
Gentleman, 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 for looping and stitching the supporting
tapes used in heading curtains.
In the Specification to Letters Patent No. 17619 dated 17th September, 1894,
I have described a new and improved method of hanging curtains, and my
present invention relates to a machine used for attaching and looping the
supporting tape used in connection with my said invention, the object being to
provide a machine adapted to loop and attach the supporting tape, at the one
operation, either to the curtains directly or to a supporting band which is stitched
to the curtains at the same time or afterwards.

I have illustrated my invention in the accompanying drawings, in reference
to a Wheeler & Wilson" sewing machine; only such portions of the machine
are shown as are necessary to explain the action of the apparatus, and of course
any other type of sewing machine may be employed.
Fig. I is a side elevation, Fig. II is a plan in section on the line A, A, of
Fig. I, Fig. III is a fragmentary plan showing the operative parts in position
for forming the loop in the tape, Fig. IV is an end elevation, Fig. V is a
perspective view, and Fig. VI is a view showing a portion of the curtain with
the band and the looped tape attached thereto.
1 is the arm of the machine, carrying the ordinary needle bar 2 and the
presser bar 3 with its lifter 4.
The flat supporting tape 5 (Fig. VI), which I will
distinguish by referring to as the supporting band, or briefly as the band, and
the looped tape 6, which I will briefly term the tape, and which is assumed to be
of circular cross-section in the present case, are supplied from bobbins carried
in the ordinary way from the machine arm, and they are guided-respectively
through the slot 7 and the eye 8 of the presser foot 9. Under ordinary circum-
stances, both the band and the tape would be stitched continuously to the curtain
on being fed through the machine; but in order to loop the tape, it is further
guided through the hole 10 in the movable guide 11.
This guide is journalled at 12 to the arm of the machine and it is periodically
oscillated, during the working of the machine, by the gear shown in Figs. II
and III. The worm wheel 13, driven by the worm 14 on the machine shaft,
carries the projecting tooth or cam 15 which is adapted to engage with the pin 16

page_text: on the connecting link 17 which, in turn, is pivotally connected to the lever 18
As the cam rotates, the parts
secured to the journalled spindle of the guide 11.
are brought into the position of Fig. III, in opposition to the tension spring 19;
on a slight further movement of the cam, the pin 16 escapes from the cam, and
the guide 11 springs back to the position of Fig. II.
From the action described, it is obvious that as the stitching proceeds the
tape is periodically deflected from and brought back into the line of stitching,
thus forming loops therein of the desired length, as shown in Fig. VI. The
stitching is, on the other hand, continuous so far as the band is concerned, as
the latter is guided by the fixed slot 7.
The amount of deflection of the guide 11 can be regulated by varying the
effective length of the lever 18, which is slotted for this purpose. The small
projection 20 at the foot of the guide 11 bears against the side of the tape, aud
prevents its accidental deflection out of the stitching line, and the projecting
pin 21 on the presser bar bears under the horizontal portion of the guide 11,
so that the effect of raising the presser foot is also to raise the guide 11 in
opposition to the spring 22.
In some cases the band may, for further security, be attached to the curtain
by a second continuous line of stitching along its other edge; to effect this it
is only necessary to provide the machine with a second needle and shuttle
mechanism operating in the ordinary way. On the other hand, where the texture
of the curtain is sufficiently firm, the band may be altogether dispensed with,
and the tape attached directly to the curtain.
Where a machine is provided with two needles both lines of stitching may be
used to attach the tape, when, in the case of heavy curtains, a very secure
attachment is needed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1. The improved machine for looping and stitching tapes to curtains and the
like, which consist of; a sewing machine; a movable guide through which the
tape passes before it is stitched by the machine; and means operated by the
shaft of the machine for periodically moving the latter guide so as to pull the
tape laterally clear of the line of stitching and so form the loop; substantially
as described and illustrated.
2. The improved machine for looping and stitching tapes to curtains and the
like, which consists of:-a sewing machine; a movable guide through which
the tape passes before it is stitched and which is periodically moved, by a cam
operated by a worm wheel driven from the shaft of the machine, so as to pull
the tape laterally clear of the line of stitching and so form the loop; substantially
as described and illustrated.
3. The improved machine for looping and stitching tapes to curtains and the
like which consists of:--a sewing machine; a movable guide pivoted to the
machine and adapted to be raised from the table with the presser foot, and to be
periodically moved, by a cam or equivalent device operated by the shaft of the
machine, so as to pull the tape laterally clear of the line of stitching and so
form the loop; substantially as described and illustrated.
4. In combination with a sewing machine:-a movable guide pivoted to the
frame of the machine so as to be capable of being raised with the presser foot,
O and the means for periodically vibrating the said guide about its pivot, sub-
stantially as and for the purpose described and illustrated.
5. In combination with a sewing machine: -a movable guide pivoted to the
frame of the machine so as to be capable of being raised with the presser foot;
said guide being provided with a lever to which one end of a rod is attached, the
5 other end of which rod is connected to a spring which normally tends to keep
the guide in the line of stitching, and a cam, operated by a worm wheel driven

page_text: by the shaft of the machine, and adapted to engage periodically with a pin on
the end of the rod and to vibrate the guide about its pivot; substantially as
described and illustrated.
6. In combination, the sewing machine, the presser foot with the fixed guide,
the pivoted movable guide so shaped that the pin 21 engages with it and lifts
it when the presser foot is raised, and the means for periodically vibrating the
said guide about its pivot; substantially as described and illustrated.
7. In combination; the sewing machine provided with two needles, the
presser foot of which is provided with a fixed guide for the tape and a fixed guide
for the band; a movable guide through which the tape passes; and means for
periodically moving the latter guide which pulls the tape laterally clear of the
line of stitching of one of the said needles; substantially as described.
8. The improved machine for looping and stitching tapes to curtains and the
like substantially as described and illustrated in the drawings.
