page_text: I, JOHN DARLING, of 2, Wharton Street, Kingscross Road, London, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide an appliance to facilitate the thread-
ing of needles.
In carrying out my invention I provide a loaded base plate which acts as a
support or rest for the appliance while under the threading operation. Mounted
on this base plate or cast in one piece with it there is an upright plate to which
there is pivoted one end of a bent arm lever, while the other end stands loose
towards the upper end of the plate. The upper end of this threading bar is
provided with eyelets and a small hole for the purpose of retaining the
portable needle threading device in position. The upper end of this
needle threading device is in either the form of a cut-saw or a
hook. One end of an upright arm or lever is pivoted on the opposite
side of the plate while the upper end is provided with a vertical slot and a horizontal
groove. A stop is also provided at end of the horizontal groove and a small
recess which acts as a guide for the eye of the needle. On the frame there is a
cut-out into which the thread is placed for the purpose of holding the thread against
the threader during the threading operation; or in lieu of the cut-out an upward
projection might be employed. Near the top of the front arm or lever there is a
light spring against which the threader rests so that it (the threader) can adapt
itself to the different sizes of needle eyes. Towards the bottom of the said arm there
is another spring which causes the arm to return to its normal position after the
threading operation has been performed as will be hereafter described. A
hinged cover may be fitted on one side to enclose the working parts.
The modus operandi is as follows :-The eve of the needle is placed in the
horizontal groove until the end of it rests in the guide at back. It is then pushed.
forward against the stop which operation causes the front arm or lever to go for-
ward thus raising the threading bar to which the threader is attached and the
latter passes up through the vertical slot and thence through the eye of the needle.
The tip end of the thread, which is preferably thinned or tapered, is then placed
in front of the threader which has been passed through the needle eye and when the
needle has been drawn forward, the thread, being held against the cut-out or pro-
jection, is automatically drawn under or against the threader when the needle
becomes threaded. To release the end of the thread after this operation, a pro-
jecting piece of metal is fixed to the upper side of the front arm and this is simply
pressed forward when the thread is released or a recess in the frame might serve
the same purpose. In such case the upright bar is simply pushed back."
The appliance may be so arranged as to contain or hold two or more threaders
of different sizes, and it is so constructed that a new or different sized threader can
be replaced without trouble.

parts.

I, JOHN DARLING, of 2, Wharton Street, King's Cross Road, London, Engineer,
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:
1
My invention has for its object to provide: an appliance to facilitate the threading
of needles.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings of which,
Figure 1 is a front elevation of the apparatus shewing in dotted lines the work-
ing parts.
Figure 2 is a plan.
זיה
Figure 3 is an end view of the stand.
Figure 4 is a separate view of the working parts.
Figure 5 is a perspective view of the apparatus showing the operation of the
threading.
Figure 6 is a similar view after the threading of the needle has been performed.
Figure 7 is a fragmental view shewing a different form of the threader.
In carrying out my invention, I provide a loaded or weighted base plate A, which
acts as a support or rest for the appliance while under the threading operation.
Mounted on this base, or as shown on the drawings herein, cast in one piece with it,
there is an upright plate or standard B having a recess or slit C in the centre, shewn
more particularly in Figure 3, into which the working mechanism is placed.
The working parts of the threader consists of a lever D to which there is pivoted
at a a bent arm lever E which I will hereafter for convenience designate the thread-
ing bar E. The upper end of this threading bar E is provided with 'an eyelet F
and a small opening or slit G for the purpose of retaining the needle threading
device H in position and also enabling it to be removed and a fresh one or one of a
different size substituted at any time without trouble. The upper end of the
needle threading device H may have a hooked end as shewn in Figure 4, or it
may be in the form of saw cuts as shown in Figure 7. One end of an upright arm
or lever I is pivoted to the lever D at 6 while the upper end is provided with a
vertical slot K and a horizontal groove L. A stop M is also provided at end of
horizontal groove L with a small recess T in it, which acts as a guide for the eve
of the needle N. On the upper end of the upright plate or standard B there is a
recess or cut-out into which the tip of the thread is placed with the view of
holding the thread against the threading device H during the threading operation;
or in lieu of the cut-out or recess 0, a little upward projection or pins might be
used which would effect the same object. I provide a spring Q to allow the up-
right arm or lever.I and with it the threading bar E to return to their normal
positions after the threading operation has been performed as will be hereinafter
described,

page_text: The modus operandi is as follows:-The eye end of the needle N is placed in the
horizontal groove L until the end of it rests in the guide T at back. It is then
pushed forward against the stop M which operation causes the front arm or lever I
to go forward thus raising the threading bar E to which the threader H is
attached (shewn dotted lines Figure 4) and the latter passes up through the vertical
slot M and thence through the eye of the needle N. The tip end of the thread,
which is preferably thinned or tapered, is then placed across the cut-out or recess 0
in front of the threader H, which has been passed through the needle eye (seen in
Figure 5) and when the needle has been drawn forward the thread being held
against the cut-out 0 or projection, is automatically drawn under or against the
threader H, when the needle becomes threaded, as shewn in Figure 6. To release
the end of the thread after this operation a projecting piece of metal is fixed to the
upper side of the front arm, and this is simply pressed forward, when the end is
released, or as shewn in the drawings, a recess U in the standard I might serve the
same purpose. In the latter case the upright bar is simply pushed back, and the
thread pulled down when it becomes released from the apparatus. A little stop W.
is, or may be, provided to retain the upright bar or lever in its normal position.
The appliance may be si arranged as to contain or hold two or more threaders
of different sizes.
Having now particularly described and ascertained the nature of my sail
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a needle threader, the stand for containing the working mechanism,
constructed substantially as described and illustrated on the accompanying sheet
of drawings.
2. In a needle threader, the combination of the lever D, upright arm or lever I,
threading bar E with threading device H, and so arranged that, when the needle is
pushed into the apparatus, it causes the end of the threading device to pass up
through the eye of the needle, substantially as described and illustrated on the
accompanying sheet of drawings.
3. In a needle threader, the arrangement by which the thread, when the needle
has been drawn forward, is automatically drawn under or against the threading
device, substantially as and for the purposes herein before described and illustrated
on the accompanying sheet of drawings.
4. In needle threaders, the method by which the thread is released from the
apparatus after the threading operation has been accomplished, substantially as
described and illustrated on the accompanying sheet of drawings.
5. In needle threaders, the arrangement by which the threading device is held
in position and also capable of being removed and a fresh one, or one of a different
size, substituted, substantially as described and illustrated on the accompanying
sheet of drawings.
6. The general arrangement, combination and operation of the parts constituting
a needle threader, substantially as described and illustrated on the accompanying
sheet of drawings.
