Office," No. 8, Southampton Buildings, Chancery Lane, in the County of
Middlesex, Civil Engineer, for the Invention of "IMPROVED SEWING
MACHINERY AND STITCH FORMED BY THE SAME."-A communication from
abroad by John Jay. Sibley, of the City, County, and State of New York,
United States of America.
Sealed the 22nd September 1865, and dated the 17th June 1865.
PROVISIONAL SPECIFICATION left by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition, on the
17th June 1865.
I, GEORGE HASELTINE, of the "International Patent Office," No. 8, South-
ampton Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of the said Invention for "IMPROVED SEWING
MACHINERY AND STITCH FORMED BY THE SAME," a communication, to be as
follows:-
These improvements relate chiefly to mechanism for making a three or
more threaded stitch herein-after more particularly specified, the first thread
being carried by the needle, the second by the bobbin, and the third by the
thread carrier of my improved mechanism. Said mechanism consists chiefly

page_text: "
of an independent frame supporting the under thread carrier with its lever
and other parts acting in connection therewith in such a manner that it may
be so attached to the "Wheeler and Wilson" sewing machine, patented in
the name of Auguste Edouard Loradoux Bellford, October 6, A.D. 1852,
No. 251, as to bring the said thread carrier and its actuating lever in co-opera-
tive relation with the hook and needle, and also with the cam that advances
the cloth. This frame is provided with a ring slide, having a tongue which
fits into the ring slide groove of the "Wheeler and Wilson" machine, and is
secured therein by means of a screw. This ring slide takes the place of the
ring slide of the "Wheeler and Wilson" machine, and has the same operative
relation to the bobbin and rotating hook. The under thread carrier is fixed
on a shaft supported in a frame, and operated by an arm fixed on another
shaft. A notch is formed in the end of this arm for a stud or projection
fixed on the under thread carrier shaft to work upon; the said arm is operated
by another arm receiving its motion from the ordinary feed cam of the
Wheeler and Wilson" machine, and the under thread carrier is returned to
its position by means of a spring, the play thereof being regulated by a screw
or other suitable device. To the frame which supports the under thread
carrier and arm another frame is attached, and on this latter is fixed the post
carrying the under thread tension and the under spool spindle. The lower
end of the shaft on which the under thread carrier is fixed rests upon a step,
and this step is held up by a spiral spring, and has two small ears projecting
out through a slot formed in the stand which supports the under thread
carrier shaft, and is thereby kept from reciprocating with, said shaft. By
pressing down upon the thread carrier the spiral spring closes up and permits
said thread carrier to fall until it is disconnected from the arm acting thereon.
The thread carrier may then be swung round from under the cloth plate of
the "Wheeler and Wilson" machine, so that the eyes of said thread carrier
can be easily got at to thread. The ears of the step bear against the top
of the slot in the stand, which prevents the spring from pushing it so high as
to bind on the end of the shaft. The needle in the vibrating arm of the
machine descends with its thread through, the material. When the loop of
the needle thread has been caught and spread upon the rotating hook as usual
in the "Wheeler and Wilson" machine, and the needle retracted, the under
thread carrier passes through said loop of needle thread carrying its own thread
back of the track of the needle, thus introducing a loop of under thread
through a loop of needle thread. It remains in this position until the, needle
has again descended, carrying its own thread through the loop of the under
thread, whilst the rotating hook is securing and spreading this second loop of

page_text: needle thread (while it is yet spread upon the rotating book), and carries its
own thread across the track of the needle as before. The needle and bobbin
threads being interlaced as usual in the "Wheeler and Wilson" machine, the
third or under thread carrier is drawn up by the needle thread to the cloth
and tension plates, between which the thread passes to keep it taut. When
the bobbin is threaded and used with the attachment the new and improved
machine made stitch for embroidery and sewing is formed. If the bobbin is
not threaded the attachment described when placed upon a
"Wheeler and
Wilson" machine forms a double loop stitch.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on
the 4th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of June, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Haseltine, Her special licence that I, the said
George Haseltine, my executors, administrators, and assigns, or such
others as I, the said George Haseltine, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVED SEWING MACHINERY AND STITCH
FORMED BY THE SAME," a communication, upon the condition (amongst others)
that I, the said George Haseltine, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare the nature of the said Invention, and in what manner the same is

page_text: v, the step thereof; w, the screw that secures the under thread carrier in
shaft e; x, the spring under the step of shafte; y, the step between the spring
and shaft e, on which shaft e rests; %, the ring slide groove of the ordinary
"Wheeler and Wilson" sewing machine; z¹, the needle; p', the rotary hook.
"
The purpose of my improvement is to enable a "Wheeler and. Wilson
sewing machine to make the three (or more) threaded stitch shown in Figure 7,
and herein-after described. This is accomplished as follows:-Unscrew the
thumb screw that secures the ring slide of a "Wheeler and Wilson" machine
in place, remove the ring slide, and put the attachment on in its place; the
tongue o' of the attachment being made to slide in ring slide groove z of the
machine, the ring slide thumb screw of the machine will secure the attach-
ment in place, ring slide j of the attachment secured to stand f, taking
the place of the removed ring slide of the machine, and having the same
operative relations to bobbin and rotary hook p² of.the "Wheeler and
Wilson" machine that the removed ring slide of the machine has. Motion is
communicated to the under thread carrier (in one direction) through the arm /
and arm g, connection 6 and shaft e from the feed cam of the "Wheeler and
Wilson "machine, bearing directly upon arm 7 at point c', and in the opposite
direction by the spring m. The operation will be as follows:-Needle z¹
descends with its thread through the material;, when the loop of needle
thread has been caught and spread upon the rotating hook as usual in the
"Wheeler and Wilson" machine, and the needle retracted, the under thread
carrier passes through said loop of needle thread, carrying its own thread
back of the back of the needle (thus introducing a loop of under. thread
through a loop of needle thread), in which position it remains until the needle
has again descended, carrying its own thread through the loop of under thread.
Whilst the rotating hook is securing and spreading this second loop of needle
thread the under thread carrier d is withdrawn from the first loop of needle
thread, and immediately enters the second loop of needle thread (while it is
yet spread upon the rotating hook), and carries its own thread across the back
of the needle as before. The needle and bobbin threads being interlaced as
usual in the "Wheeler and. Wilson " machine, the third.or under thread carrier
thread is drawn up by the needle thread to the cloth and tension plates & and t,
between which the thread passes to keep it taught. .Shaft e rests upon step y,
and step y is held up against the bottom of shaft e by spiral spring a, the step
having two small ears projecting out through slot ¹ in standf, which keeps the
-step y from reciprocating with shaft e. By pressing down upon thread carrier d
spiral spring a closes up, and permits thread carrier d to fall until it discon-
nects from arm g, and it may then be swung round from under the cloth plate

page_text: of a "Wheeler and Wilson" machine, so that the eyes of the thread carrier
can be easily got at to thread. The ears of the step bear against the top of
the slot in stand f, which prevents the spring from pushing it so high as to
bind shaft e.
Two or more threads may be placed in the bobbin and thread carrier so
as to secure a variety of colors when desired. When the bobbin is threaded
and used with the attachment the new and improved machine made stitch for
embroidery and sewing shown in Figure 7 is formed; A representing the
material, B the upper thread, C the lower, and D the filling thread, without
any of the threads being drawn up so as to show the manner in which it is
made. The principal advantage of this stitch is that a greater quantity of
thread or cord is thrown upon that side of the goods on which the embroidery
is to show; it may be made by hand or any suitable machinery that will throw
a threaded shuttle or bobbin through the loops made by the piercing needle
of a so-called "double loop" stitch sewing machine, the third or filling thread
so securing the whole that it is impossible to unravel it. If the bobbin is not
threaded the attachment described when placed upon a "Wheeler and Wilson"
sewing machine forms a "double loop" stitch.
Having thus fully described the said Invention, as communicated to me by
my foreign correspondent, and shown how the same may be conveniently
and advantageously carried into practice, I claim,-
First, the separate organization of the under thread carrier, with its lever
in an independent frame in such a manner that it may be at once attached to
the "Wheeler and Wilson" sewing machine in the place of the ring slide, 60
as to bring the thread carrier and its actuating lever in co-operative relation
with the hook and needle of the cam, that advances the cloth substantially as
described.
Second, I claim the attachment described adjustable to a "Wheeler and
Wilson" sewing machine, to make a stitch of three or more threads, substan-
tially in the manner set forth.
"
Third, I claim the combination of the attachment described with the needle,
rotating hook, bobbin, and other operative parts of a "Wheeler and Wilson
sewing machine, except the ring slide.
Fourth, I claim the ring slide j, constructed and operating substantially as
described.
Fifth, I claim the combination of the needle z¹, bobbin k', thread carrier d,
and ring slide j, constructed and operating together substantially as described.
Sixth, I claim the step y, constructed and operating, substantially as
described:

page_text: Seventh, I claim the stitch described and shown in Figure 7 of the
Drawings.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this First day of September, in the year of our Lord
One thousand eight hundred and sixty-five.
GEORGE HASELTINE. (L.S.)
Witness,
EDWARD G. BRASIER.
