Improvements in or applicable to Ornamental Sewing Machines for
Sewing Quilts, Quilted Linings, Skirts, and the like.
JOHN HAPPE of Springfield, Sale in the County of Chester, Machinist, do
hereby declare the nature of this invention to be as follows:-
This invention relates to multiple needle sewing machines for sewing ornamental
figures on quilts, skirts, quilted linings &c. in which the lines of stitching
constituting the quilted design are produced by the continuous feed of the material
to be quilted on multiple needle traversing sewing machines which machines are
traversed by means of pattern cams or other similar devices at right angle to the
feed of the cloth according to the design to be produced.
It has hitherto been the practice to feed a length of fabric comprising several
quilts continuously on the sewing machines, to stitch the quilted design, forming
the central portion of say: A number of bed quilts along the entire length of
fabric without regard to the borders of the several quilts through which the stitches
are thus caused to pass and afterwards to remove the stitches so produced from
the sewn borders. The result of this method has been to more or less injure or to
disfigure the fabric.
Now my invention consists in so arranging the feed of the fabric and the
positions of the sewing machines or rows of needles that although still producing a
number of complete quilts from one length of fabric I avoid the necessity of
stitching across the borders of the several quilts as was hitherto found necessary in
producing the ornamental centre of each quilt.
In performing my invention I use by preference two traversing multiple needle-
carriages each carriage containing in this case a single row of sewing needles & I
actuate these said carriages by means of pattern cams or other similar devices in
the manner as hereafter described. In some cases I may use one traversing and
one stationary sewing machine.
At the commencement of the feed of the fabric the single row of sewing-needles
on the carriage furthest from the feed-rollers is set so as to start its ornamental
sewing at the commencement of the centrepiece of the first quilt to be sewn (each
quilt consists of a centrepiece surrounded by an equal border) and the feed of the
fabric is continued until the end of the said centrepiece is reached the sewing
having meanwhile been continuous. It is now necessary to feed the fabric forwards
without sewing across the remaining border of the first quilt and the beginning
border of the second quilt which object is attained by drawing forward the fabric
the required distance say by means of a lever, ratchet wheel and catch mounted on
the feed roller whilst the sewing needles are out of the quilt or material and
afterwards the feeding and sewing is continued as before. After having sewn the
centre of the first quilt by means of the back machine and drawn the fabric
forward as described the formost machine (that nearest the feed rollers) commences
to sew its ornamental lines to complete the centre or centrepiece of the first quilt
and at the same time the back machine is stitching the centrepiece on the second
quilt and thus the alternate feeding and sewing and drawing forwards by means of
say the hand-lever is continued for the entire length of the fabric.
In order to make the machine as compact as possible the two rows of needles or
the two carriages are placed nearer together than the length of an entire quilt so it
is found necessary to take up the surplus length of quilt between the two said rows

page_text: of needles by passing the said fabric over or around one or more rollers, bars or
their equivalents mounted either above or below the level of the fabric which
rollers or bars or their equivalents (either one or more) are or is capable of
adjustment as to take up a greater or less length of surplus fabric according to the
varying lengths of quilts or other quilted articles.
Another feature of my invention is the mechanism I employ for setting the
fabric in relative position with the needles so that the sewn pattern of the centre-
piece shall have a more finished appearance by keeping the outside sewn figures of
the centrepiece at such a distance from the surrounding border lines of the said
centrepiece that the said figures may be complete in themselves, say for instance in
the case of squares, circles or other similar stitched figures.
f
The pattern cam on each sewing-machine-carriage has a toothed wheel by which
it is driven through intermediate toothed wheels from the feed rollers. Now in
order to set the fabric with respect to the rows of sewing needles for the purpose
described it is necessary to disconnect the pattern-cam-movement from the fabric-
feed movement. To enable me to do this I arrange that the toothed wheel on the
forward pattern cam shall be double the width of the remaining toothed wheels, so
that by drawing the intermediate wheel out of gear with the feed roller toothed
wheel the feed roller and pattern movements cam or cams are disconnected whilst
the intermediate wheel still remains in gear with the said pattern cam-wheel and
that the adjustment of the fabric with respect to the needles can be effected which
can be most-conveniently done by means of a lever on the said intermediate wheel
when the required adjustment of the pattern-cam or cams has been made the
intermediate wheel can again be put in its former position and the connection
between the cam or cams and feed roller or feed rollers again effected.

Improvements in or applicable to Ornamental Sewing Machines for
Sewing Quilts, Quilted Linings, Skirts, and the like.
I JOHN HAPPE of Erste Schulgasse, Wandsbek, by Hamburg, Germany
Machinist 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 multiple needle sewing machines for sewing ornamental
figures on quilts, quilted linings and the like articles in which the lines of stitching
constituting the quilted design are produced by the continuous feed of the material
to be quilted on multiple needle traversing sewing machines which machines are
traversed by means of pattern cams or other similar devices at right angles to the
feed of the cloth according to the design to be produced.
It has hitherto been the practice to feed a length of fabric comprising several
quilts continuously on the sewing machines to stitch the quilted design forming the
central portion of bed quilts along the entire length of fabric without regard to the
borders of the several quilts through which the stitches are thus caused to pass and
afterwards to remove the stitches so produced from the sewn borders. The result
of this method has been to more or less injure or disfigure the fabric. Now my
invention consists in so arranging the feed of the fabric and the positions of the
sewing machines or rows of needles that although still producing a number of
complete quilts from one length of fabric I avoid the necessity of stitching across
the borders of the several quilts as was hitherto found necessary in producing the
ornamental centre of each quilt.
On the accompanying drawings

page_text: Fig. 2 a plan of so much of a multiple needle quilt sewing machine as is necessary
to shew the application of my improvements thereto.
In performing my invention I use by preference two traversing multiple needle
carriages 1 and 2 each carriage containing a single row of sewing needles and I
actuate these said carriages by means of pattern cams 3 in the usual manner.
some cases one carriage may be stationary and the other traversing.
In
At the commencement of the feed of the fabric 4 the single row of sewing needles
on the carriage 1 is set so as to start its ornamental sewing at the commencement
of the centrepiece of the first quilt to be sewn (each quilt consists of a centrepiece A
surrounded by an equal border B) and the feed of the fabric is continued until the
end of the said centrepiece is reached the sewing having meanwhile been continuous.
It is now necessary to feed the fabric forwards without sewing across the remaining
border of the first quilt and the beginning border of the second quilt which object
is attained by drawing forward the fabric the required distance; say by means of
a lever 5 catch 7 and ratchet 6. mounted on the feed roller 8 whilst the sewing
needles are out of the quilt or material and afterwards the feeding and sewing is
continued as before.
After having sewn the centre A of the first quilt by means of the machine 1 and
drawn the fabric forward as described the foremost machine 2 commences to sew
its ornamental lines to complete the centre A of the, first quilt and at the same
time the back machine 1 is stitching the centrepiece on the second quilt and thus
the alternate feeding and sewing and drawing forward by means of the handlever 5
is continued for the entire length of the fabric.
In order to make the machine as compact as possible the two rows of needles 1
and 2 or the two carriages are placed nearer together than the entire length of a
quilt so it is found necessary to take up the surplus length of quilt between the two
rows of needles by passing the fabric over or around one or more rollers 9 mounted
as I prefer on uprights 10 provided with teeth 11 by which they are capable of
adjustment through the worm pinion and hand wheel 12 to take up a greater or less
length of surplus fabric according to the varying lengths of quilts.
Another feature of my invention is the mechanism I employ for setting the fabric
in relative position with the needles 1 and 2 so that the sewn pattern of the centre-
piece A shall have a more finished appearance by keeping the outside sewn figures
(as C in plan view Fig. 2) at such a distance from the surrounding border B that
the said figures may be complete in themselves say for instance in the case of
squares, diamonds or circles or other similar stitched figures.
The pattern cams 3 and 3ª on each sewing machine carriage have toothed
wheels 13 and 13" by which they are driven through intermediate toothed wheels 14
and 14° from the feed roller 8. Now in order to set the fabric with respect to the
sewing needles for the purpose described it is necessary to disconnect the pattern
cam movement from the fabric feed movement. To enable me to do this I arrange
that the toothed wheel 13 on the foremost pattern cam 3 shall be double the width
of the remaining toothed wheels 14 and 15 so that by drawing the intermediate
wheel 14 out of gear with the feed roller toothed wheel 15 the feed roller and pattern,
cam movements are disconnected whilst the intermediate wheel 14 still remains in
gear with the said pattern cam wheel 13 and that the adjustment of the fabric with
respect to the needles can be effected which can be most conveniently done by
means of a lever or handle on the said intermediate wheel 14 when the required
adjustment of the pattern cam has been made the intermediate wheel can again be
put into its former position and the connection between the cams 3 and 3 and
feed roller 8 again effected.
Having thus 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 :-
1st. In a multiple needle quilt sewing machine the employment of two needlebars

page_text: and two needle carriages to complete the sewing of each distinct quilt centre in
combination with the rollers for taking up the superfluous fabric substantially as
described and illustrated on the accompanying drawing.
2nd. The mechanism employed for setting the fabric to be sewn with reference to
the sewing needles substantially as described and illustrated.
