I, JOHN Fox of 60 Blurton Road, Clapton Park, London, Machinist, do hereby
declare the nature of this invention to be as follows:-
The object of this invention for facilitating the threading of Sewing Machine
needles is carried out by means of an apparatus which consists of an open conical tube
for guiding the thread to the eye of the needle and a pair of nippers so arranged that
they can be closed upon the thread as soon as it has passed through the eye of the
needle and by drawing it away complete the operation of threading the needle.

Improved Needle Threader.
I, JOHN Fox, late of 128 London Wall in the City of London, and now of
60 Blurton Road, Clapton Park in the County of Middlesex, 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:
-
The object of this invention for facilitating the threading of Sewing Machine
needles is carried out by means of an apparatus which consists of an open conical tube
for guiding the thread to the eye of the neeedle and a pair of nippers so arranged that
they can be closed upon the thread as soon as it has passed through the eye of the
needle and by drawing it away complete the operation of threading the needle.

page_text: Fig. 1. in the drawings is a top or plan view of the apparatus.
Fig. 2. is a plan view of the same with the top leaf or jaw of the apparatus removed
shewing in detail the manner in which the arm is jointed to the bottom jaw and also
the way in which the spring is attached to the same.
Fig. 3. is an edge view of the apparatus looking towards the open end of the
conical tube.
The jaws of the apparatus are designated by the letter a.
b. is the open conical tube.
c. is an arm which carries the conical tube and which is jointed to the bottom leaf
or jaw of the nippers as shewn at d. and is kept in position by means of a spring e.
one end of which is fixed to the bottom leaf of the nippers at f. whilst the other end
plays freely in a notch cut in the edge of the arm at g. The effect of the spring is to
press the point of the conical tube towards the jaws of the nippers.
1. is a wedge like extension of the top leaf of the nippers it is bent down at a right
angle until its edge is in contact with the edge of the arm c. The effect of the wedge
upon pressure being applied to the sides of the nippers is to cause the point of the
conical tube to recede from the jaws of the nippers.
J. is a V shaped notch cut in the edge of the nippers directly opposite to the point
of the conical tube-its purpose is to form a guide for placing the point of the tube in
contact with the needle and to assist in holding it in position.
The threading of sewing machine needles is effected as follows.
The needle having been properly fixed in the machine and raised to its highest
position press the sides of the nippers together-this will cause the point of tho
conical tube to recede from the jaws of the nippers-then place the back of the needle
in the V shaped recess or notch and remove the pressure from the nippers the point
of the conical tube will then enter the groove in front of the needle, and by gently
moving it upwards or downwards as may be necessary it will be felt to pass into the
eye of the needle. The end of the thread being then passed through the conical tubo
will pass also through the eye of the needle and through the jaws of the nippers which
being closed upon it, will cause the point of the conical tube to again recede from tho
eye of the needle and enable the thread to be drawn through with greater facility than
by threading the needle in the usual way.
Crdinary sewing needles may be threaded by simply laying the needle in the
V shaped groove with the eye in such a position that the point of the conical tube
will enter the eye and then passing the thread through the tube and through the eye
of the eye of the needle in the manner already described in the case of the sewing
machine needles.
Having now particularly described and ascertained the nature of my invention and
in what manner the same is to be performed, I declare that what I claim as new is
"The combination of the nippers a. the conical tube b. the arm e. and the spring e.
as arranged, described and illustrated herein and for the purpose set forth."
