66, Chancery Lano, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVED EMBROIDERING APPA-
RATUS APPLICABLE TO SEWING MACHINES." -A communication from
abroad by George M. Ramsay, of the City and State of New
York, United States of America.
Sealed the 9th February 1875, and dated the 10th August 1874.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 10th August 1874.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do
hereby declare the nature of the said Invention for "IMPROVED EM-
BROIDERING APPARATUS APPLICABLE TO SEWING MACHINES," to be as follows:-
The object of this Invention is to interlock a heavy embroidering
thread with the sewing thread of a sewing machine in such a manner as
to produce embroidery on the upper side of the fabric.

page_text: In carrying out this Invention a horizontal embroidering needle is
used in connection with a presser foot, and a reciprocating motion is
given thereto for the purpose of throwing the embroidery thread across
the path of tho sewing needle through the ascent and descent of the
vertical needle bar. The prosser foot is provided with curved bracket
arms for supporting a vertical spindle which is cranked at its lower end
to receive the stem of the embroidery needle. This spindlo is fitted
with a forked head which carries a cam formed of bent wire within
which, as in a grooved cam, plays the head of the binding screw that
secures the vertical needle to its bar. Thus as the needle bar ascends
and descends its screw will, by acting on the cam, impart an axial
motion to the vertical spindlo, and thereby give a reciprocating motion
to the embroidery needle. This needle is loose in its socket and is held
in position by a spring which yields when required to modify the action
of the cam.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 10th February 1875..

Invention for "IMPROVED EMBROIDERING APPARATUS APPLICABLE TO SEWING
MACHINES," being a communication to me from abroad by George M.
Ramsay, of the City and State of New York, United States of
America, upon the condition (amongst others) that I, the said Alfred
Vincent Newton, 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 Alfred Vincent Newton, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that.
is to say):-
The object of this Invention is to interlock a heavy embroidering
thread with the vertical needle throad of a sewing machine in such a
manner as to produce embroidery on the face of the fabric in tended
to be ornamented.
In effecting this object a horizontal embroidering needle is used in
connection with a presser foot, and a reciprocating motion is given to
3. that needle for the purpose of throwing the embroidering thread across
the path of the sewing needle through the ascent and desent of the
vertical needle bar.

Fig. 2 in side elevation so much of a sewing machine with the
improved embroidery. apparatus applied thereto as will serve to explain
the construction and operation of tho apparatus; Fig. 3 is a plan view
of this apparatus, and Fig. 4 is a diagram illustrating the action of the

machine; B is the needle bar of the vertical needle b;.and: 6 is the screw

of which a pair of curved bracket arms e projects. These arms serve.
.:

page_text: to carry a vertical spindle D which is cranked at its lower end to receivo
a horizontal embroidering needle E, which is pivotted to its cranked
extremity. This spindle D carries at its upper end a cross head to
which is attached a cam F formed of two cranked wires set vertically
and parallel or nearly so to each other, see the detached view, Fig. 5.
Into this cam F projects. the head of the screw b', which in its rising-
and-falling motion will bear alternately on opposite sides of the cam,
and thereby cause the spindle D to rock in its bearings, the object of
which rocking of the spindle is to throw the embroidering thread across
the line of traverse of the sewing thread. d is a spring attached to tho
presser foot stem, and bearing upon the vertical spindle so as to put a
friction presser upon it, and thereby sustain it in the position into which
it is rocked; e is a spring attached to the spindle D and bearing upon the
short vertical stem of the needle E. This spring allows of the needle E
yielding when brought into contact with and pressed against the vertical
needle by the downward action of the screw head on the cam F of
the spindle D. The embroidering thread is led down from a bobbin
situate in any convenient position to an cyclet c' on the presser foot. It.
is then led through holes in the embroidering needle, as shewn at Fig. 4,
and coming out near the point of the needle is, on starting the machine,
held down to the work.
The vertical needle is threaded in the usual way and the stitches which
it forms are secured at the back of the fabric by a locking thread.
*Supposing now the embroidering needle to be in the position of Fig. 3,
that is, at the back of the vertical needle, and the vertical needle to be
descending to form a loop below the fabric to be ornamented, tho
screw b¹ of the needle bar will in passing over the part ƒ of the cam F
rock the spindle D, and thereby bring its needlo E into the position
shewn at Fig. 6, the spring e yielding to allow the needle E to slide past
the vertical needle, which as before stated is in the work.
By this motion
of the needle E the embroidering thread (its end being supposed to bo
held down or secured to the work) will be laid down around the back of
the vertical needle. When the loop of the vertical needle thread is secured
below the fabric by a shuttle or looper thread as is well understood the
needlo will rise out of the work, and in doing so the screw head b' will
strike against the part f* of the cam F (Fig. 5) and move round the
needlo E from the position of Fig. 6 to that of Fig. 8. This motion of
the needle E taking place at or about the time that the work is fed

page_text: forward the effect will be to lay the embroidery thread on the work in
such a position that when the vertical needle next descends it will be in
front of that needle. The same actions of the cam F and needle E
already described will then be repeated, and stitches will be made by the
vertical needle from loop to loop of the embroidering thread as indicated
at Fig. 4.
Having now set forth the nature of the Invention of "Improved
Embroidering Apparatus applicable to Sewing Machines," as commu-
nicated to me by my foreign correspondent, and explained the manner
of carrying the same into effect, I wish it to be understood that under
the above in part recited Letters Patent I claim, the arrangement of
mechanism above described for throwing the embroidering thread across
the path of the vertical sewing needle or the line of stitches formed by
that needle, and ensuring the attachment of the embroidering thread to
the face of the fabric.
In witness whereof, I, the said Alfred Vincent Newton, have
hercunto set my hand and seal, the Tenth day of February,
in the year of our Lord One thousand eight hundred and seventy-
