Improvements in Sewing Machines.
A communication by KASIMIR VOGEL, of Chelsea, in the State of Massachusetts,
one of the United States of America.
I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to improve the construction of sewing machines
whereby novel stitching composed of several threads may be made in any part of
material to be stitched, i.e., the stitch may be used to produce strong ornamental
seam either in the body of material or along an edge.
My improved machine contains a needle-bar having one, or it may be more, eye
pointed thread-carrying needles, and an under-thread to lock the loop or loops of
needle thread, and the machine also has cooperating with its stitch-forming
mechanism a spool having one or a series of auxiliary threads which are led to the
stitchmaking point, the spools carrying such threads being rotated in the same
direction rotation after rotation about the longitudinal center of the needle-bar, so
that the said auxiliary threads are interwoven or interlocked at the surface of the
material with needle thread or threads, and in this way I may make a ridge or wale
of thread to resemble a cord or braid, and by varying the colours of the auxiliary
threads with relation to each other and to the needle threads said cord or braid may
be more or less ornamental in appearance.
The greater the number of needles carried by the needle bar the wider the cord
or braid to be made.
My invention consists essentially in a sewing machine containing the following
instrumentalities, viz. -A hollow needle-bar; one or more eye-pointed needles
carried thereby; a complemental stitch-forming device; suitable devices to actuate
the same to form stitches; a thread carrier containing one or more auxiliary threads
and devices to rotate the auxiliary thread carrier rotation after rotation about the
longitudinal centre of the needle-bar whereby said auxiliary thread or threads
leading from said carrier down to the material are interlocked or interwoven
together with the needle thread or threads at the stitch-making point.

Improvements in Sewing Machines.
A communication by KASIMIR VOGEL, of Chelsea, in the State of Massachusetts,
one of the United States of America.
I, ALFRED GEORGE BROOKES of 55 and 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 has for its object to improve the construction of sewing machines
whereby novel stitching composed of several threads may be made in any part of the
material to be stitched, i.e., the stitch may be used to produce a strong ornamental
seam either in the body of the material or along an edge.

My improved machine herein to be described, contains a needle-bar having one,.
or it may be more, eye pointed thread carrying needles, and an under thread to
lock the loop or loops of needle thread, and the machine also has co-operating with
its stitch-forming mechanism a spool having one or a series of auxiliary threads
which are led to the stitch making point, the spools carrying such threads being
rotated in the same direction rotation after rotation about the longitudinal centre
of the needle-bar so that the said auxiliary threads are interwoven, or interlocked,
at the surface of the material with needle thread, or threads, and in this way I may
make a ridge, or wale, of thread to resemble a cord, or braid, and by varying the
colors of the auxiliary threads with relation to each other and to the needle threads,
said cord, or. braid, may be more, or less, ornamental in appearance.
The greater the number of needles carried by the needle-bar the wider the cord
or braid to be made.
My invention comprehends a sewing machine containing the following instru-
mentalities, viz. -A hollow needle-bar; an eye pointed needle or eye-pointed
needles carried thereby; a complemental stitch-forming device; suitable devices to
actuate the same to form stitches; an auxiliary thread-carrier surrounding said
needle-bar loosely and containing two, or more, auxiliary threads; and devices to
slowly revolve the auxiliary thread-carrier revolution after revolution about the
longitudinal centre of the needle-bar, the stitch forming mechanism making two, or
more stitches, during each revolution of the said auxiliary thread carrier whereby
said auxiliary threads leading from said thread carrier down to the material are
interlocked, or interwoven, with first one and then the other of the needle threads at
the stitch making point, substantially as will be described.
Other features of my invention will be hereinafter described and stated in the
claims at the end of this Specification.
Figure 1 in side elevation partially broken out shews a sufficient portion of one
well known form of sewing machine with which I have embodied my invention;
Fig. 2, an under side view thereof.
Fig. 3, represents the hollow needle-bar carrying one, or more, needles and the
spool surrounding the same and adapted to carry the auxiliary threads to be
referred to.
Fig. 4 is a detail showing the lower end of the hollow needle-bar, with the
needle-holder in section, and a needle;
Figs. and 6 details of the parts at the lower end of the needle-bar to shew the
tbread outlets.
Fig. 7 is a detail shewing the spool-case detached from the needle-bar, the spool
to carry the auxiliary threads being removed;
Fig. 8 a modification to be described, and
Fig. 9, on an enlarged scale shews several stitches as they will appear on the
surface of the material when the number of sets of threads employed corresponds
with those shewn in Fig. 1, the drawings shewing the thread, however, as not drawn
up taut into cord or braid form.
Referring to the drawings A represents the bed plate, A' an overhanging arm
connected thereto it having suitable bearings for the reception of the shaft A³
having at its front end a suitable crank or equivalent device to enter a cam
block A³ instrumental in imparting to the needle-bar A* its reciprocating
movements.
The shaft A is represented as provided with a bevel gear B engaging a bevel
gear B' fast on a vertical shaft B2 provided at its lower end with a suitable crank B³
connected by link B with and so as to reciprocate a shuttle carrier B³ which in
turn actuates a shuttle 16 carrying the under thread, the face of the shuttle running
against a suitable shuttle race B'. The parts for reciprocating the needle-bar and
the shuttle and its actuating parts, and the feed device C and its actuating devices
are herein shewn as of the well known Singer family type, but instead of the
particular devices shown I may employ any other usual or well known devices for

page_text: reciprocating the needle-bar and actuating the under thread carrier. The needle-
bar A employed by me is hollow, as best represented in Figs. 3 and 4 and its lower
end receives the shank of a needle-holder a which may be confined in place by a
screw or pin a*. This holder has suitably confined in it by a screw a¹ the two or
more eye-pointed needles a², said screw passing through a sleeve like block a³
surrounding the needle-holder, said block being grooved externally, as at b'.
The needle-holder as best shewn in Figs. 4 and 5 has suitable thread grooves b
which communicate with thread grooves b' in the block A³ referred to. The
needle-thread or threads c taken from suitable spools or bobbins are led through a
suitable tension device e', through eyes of a suitable take-up c², down through the
hollow needle-bar, through the grooves and thence through the eyes of the
needles a². The take up herein shewn is adapted to be operated in one direction
by the needle bar, and in the other direction by a suitable spring as c³, but instead
the take-up may be operated in any other usual or well known manner so as to
control and take up the slack of and set the stitch. The presser foot D attached
to the presser bar D' is or may be as is common in the Singer or other family
machine. The hollow needle-bar is surrounded loosely by a crown wheel d, the
shank of which acts as a guide for the auxiliary thread carrier e which may be
a spool having a hollow barrel so as to surround the needle-bar and also the hub d',
this hollow barrel having wound upon it one or more auxiliary threads e¹, usually a
series of threads of the same or different colors or material, said threads being led
out through a suitable slot or guide eye as 2 in a curb f the hub of which, as
herein represented in Figs. 1 and 3, has a slot 3 to engage a pin 4 on the hub d¹ of
the said crown wheel so that said curb is supported and carried by and made to
rotate in unison with the crown wheel, the auxiliary thread e' partaking of the
same movement. Hence so arranged, when the crown gear rotates, the curb falso
rotates in unison with it.
While for convenience and simplicity I prefer to employ as the auxiliary thread
carrier a single large spool e, yet it will be obvious that my invention will not be
departed from should the curb be provided with a series of pins or guides to
receive several small spools containing each its own thread this modification
being shown in Fig. 7. The crown wheel d is engaged and rotated by a bevel
gear d³ fast on the shaft A2, and in this instance of my invention the teeth in
the crown wheel are three times the number of the teeth in the crown gear. I have
herein represented the spool as having three threads, see Fig. 1, to be woven
into or combined with the needle threads at the stitch forming point. If I
should desire to use two auxiliary threads e' then the crown wheel would have
twice the number of teeth as the bevel gear d³ and in case I should use four
threads four times the number, or the teeth would be varied to correspond to the
number of auxiliary threads to be used.
Referring to Fig. 1 the auxiliary threads e¹ are shewn as leading down to the
material, supposed to be, under the presser foot, or to the stitch making point, and
it will be understood when the eye-pointed needles are elevated out of the material
that the spool carrying the auxiliary threads will be rotated one step so as to lay
one of the auxiliary threads across the two threads leading from tlie eyes of the
needles a² to the material, and at the next descent of the needle-bar said auxiliary
thread will be crossed by the needle threads. At the next ascent of the needles,
the needle threads between the points of the needles and the material will be
crossed by a second auxiliary thread and so on, one auxiliary thread after another
of whatever size, color, or material coming into the cord or braid being made at
the surface of the material, it may be either directly upon the body of the material
or at the edge thereof, the cord or braid being larger or smaller according to the
number of the auxiliary threads used and being also of greater or less breadth or
size according to the number of eye-pointed needles used.
.
Referring to Fig. 8, describing a modification of my invention, it will be seen
that the curb f, instead of receiving within it the large spool with an open hub or

page_text: barrel to directly surround the shank d of the crown wheel, is supplied with a
series of pins, as h, to receive a series of spools as h', each spool having an auxiliary
thread to be led to the stitch forming point as described, of the threads e'. The
pins serve only the purpose of keeping the spools in place, and instead of the pins,
the spools may be held in any other usual or suitable manner so as to travel with
the curb.
Fig. 9, shows enlarged the upper side of the material with threads such as may
be laid thereon by the parts shown in Fig. 1. Referring to said figure, c' represent
needle threads, m m shuttle threads which may, or may not be drawn up to the
surface of the material, but are represented as so drawn up in order to show the
needle thread locked into the fabric.
The threads are the auxiliary threads, and I have shewn sets of three such
threads, each differently portrayed, so that their courses may be followed.
In the production of the ornamental stitch shown in Fig. 9 each of the auxiliary
threads is laid in succession under the point of first one and then the other needle,
and consequently under the needle threads and between them and the surface of
the fabric, the auxiliary thread which is laid under the point of one needle being
laid under the point of the other needle, as herein shown, after the taking of three
stitches, but if the auxiliary thread carrier had four threads and rotated only for
ninety degrees during the making of each stitch, then each of the four threads
would be brought under each needle only at each fourth stitch, as will be readily
understood.
It will be noticed in this my invention referring particularly to Fig. 8. that the
spool containing the auxiliary threads is made to turn rotation after rotation about
the longitudinal centre of the hollow needle-bar, and in this way the auxiliary
threads are interlocked, see Fig. 8, or interbraided with the needle thread or
threads in a way different from what would be the case if the axis of rotation of
the spool did not rotate about the longitudinal centre of the needle-bar.
Instead of actuating the needle-bar by a crank pin in a cam slot in a block
secured to the needle-bar, I may employ any other usual or suitable connection.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :--
1. In a sewing machine, the combination of a hollow needle-bar, two or more
eye-pointed needles carried thereby, a complemental stitch-forming device, suitable
devices to actuate the same to form stitches, a crown-wheel having a hub
surrounding the needle-bar, an auxiliary thread-carrier carrying a number of
threads provided with a central barrel and applied to the said hub, means to rotate
the crown-wheel and its hub and through them the auxiliary thread-carrier, the
stitch forming devices making two or more stitches during each revolution of the
said auxiliary thread carrier whereby said auxiliary threads leading from said
thread carrier down to the material are interlocked or interwoven with first one
and then another of the needle threads at the stitch making point, substantially as
described.
2. In a sewing machine, the vertically reciprocating hollow needle-bar provided
with a needle-holder, devices to reciprocate the needle-bar, one or more eye-pointed
needles carried by said holder, a complemental stitch-forming device, and an
auxiliary thread carrier composed of a curb having a barrel surrounding the
needle-bar loosely and supplied with a suitable number of spools, combined with a
crown-gear having a hub encircling the needle-bar and receiving the barrel of the
auxiliary thread-carrier, a gear-wheel on the needle-bar actuating shaft to engage
and revolve the crown wheel and through it the auxiliary thread-carrier less
frequently than said shaft, substantially as described.
3. The herein before described improvements in sewing machines whereby
stitching composed of several threads may be made in any selected part of the

page_text: material to be stitched-either to produce a strong ornamental seam in the body
of the material or along an edge substantially as and for the purpose set forth.
