An Improved Needle Threader.
We JOHN DARLING of 64 Albert Road Crosshill Glasgow in the County of
Renfrew Engineer WALTER GEORGE BLOW of Talbot Street Cardiff Gentleman
and JOHN DARLING Junior of 64 Albert Road Crosshill Glasgow aforesaid
Warehouseman do hereby declare the nature of the said invention to be as
follows:-
The invention relates to an improved needle threader and has for its object to
provide a device which will readily pass sewing thread through the eyes of
ordinary hand sewing needles.
In carrying the invention into effect a framework of suitable material and design
is constructed and to the front part of the base plate thereof is pivotted a vertical
arm or lever the upper part of which has an arni or bracket fixed thereto at right
angles carrying the thread retainer herein after more fully described.
The said vertical arm or lever works in a slot formed in the top of the framework.
To the rear of the base plate is pivotted the needle threading bar which extends
upward the point thereof being inserted in a small slotted piece immediately under
a hole in the vertical lever for the passage of the aforesaid thread retainer.
At some convenient part of the back of the framework a small hole is formed
for the thread to pass through from a reel or bobbin the thread being then passed
into a slot in the top of the vertical lever. When it is desired to thread the
needle its eye end is pushed to the end of the groove in the top of the vertical
lever and presses or pushes in the upper end of the said lever which turns on its
centre this motion forcing the needle threading bar to also turn on its centre and
its upper end to rise in the slotted piece in the vertical lever, and in its upward
movement the said needle threading bar pushes the thread in the form of a loop,
through the eye of the needle. As soon as the thread is pushed through the eye
of the needle, and as the vertical lever returns under the action of a spring the
thread retainer comes into position to pass through the loop formed. This is
effected by carrying the said thread retainer in a bracket attached to the vertical
lever the thread retainer being caused to slide therein by means of a diagonal slot
formed in the top of the frame, which as the vertical lever is being pressed back
by the sewing needle, causes the thread retainer to be withdrawn to allow the
needle threading bar to pass up with a loop of the thread and as the vertical lever
returns the said diagonal slot causes the thread retainer to engage with the loop
of thread formed and so hold the thread so that when the needle is withdrawn it
is threaded.
A needle threader constructed as described may be fixed to a lady's work-box
or table or be combined with a needle or cotton case.

We JOHN DARLING of 64 Albert Road Crosshill Glasgow in the County of
Renfrew Engineer WALTER GEORGE BLOW of Cardiff Gentleman and JOHN
DARLING Junior of 64 Albert Road Crosshill Glasgow aforesaid Warehouseman
do hereby declare the nature of our invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:—
The invention relates to an improved needle threader and has for its object to
provide a device which will readily pass sewing thread through the eyes of ordinary
hand sewing needles.
According to this invention when the needle is pushed into the apparatus a bar
or the like pushes a loop of thread through the eye of the needle and then a
retaining device retains the thread whilst the needle is withdrawn so that the
needle when withdrawn is threaded. We will describe the invention with reference
to the accompanying drawings premising that we do not limit ourselves to the
precise details which are illustrated.
Figure 1 is a front clevation.
Figure 2 is a longitudinal section shewing the normal position.
Figure 3 is a longitudinal section shewing the loop of thread pushed through
the of the needle.
cye
Figure 4 shews the position when the needle is withdrawn after threading and
Figure 5 is a plan.
A is a framework of suitable material such for example as metal to the front
part of the base plate of which is pivotted a vertical arm or lever b centred at 12
and pressed outwards by a spring ³ the upper end of the said lever working in a
slot formed in the top of the framework A. To the rear of the base plate is
centred or hinged at c² the needle threading bar e which extends upward the
point thereof being inserted in a small slotted piece d fitting so as to be capable
of a slight sliding movement in a slot in the upper end of the lever b. Above
this slotted piece is a hole in the lever 6 in which slides the thread retaining
device consisting of the pin e supported in the bracket attached to the said
lever b.
When it is
At some convenient part of the back of the framework A a small hole (or holes) g
is or are formed for the thread to pass through from a reel or bobbin H the thread
being then passed into the slot in the top of the vertical lever b.
desired to thread the needle its eye end is pushed to the end of the groove in the
top of the vertical lever band presses or pushes in the upper end of the said lever
which turns on its centre at 12 this motion forcing the needle threading bar c to
also turn on its centre c² and its upper end c³ to rise in the slotted piece
vertical lever band in its upward movement the upper end of the said needle
threading bar c pushes the thread in the form of a loop through the eye of the
needle as shewn in Figure 3.
in the
The piece d is pressed upon by a spring d² which allows of the slight sliding
movement of the said piece necessary to allow the upper end of the bar c to pass
through the eyes of various descriptions of needles. As soon as the thread is
pushed through the eye of the needle and as the vertical lever returns under the
action of the spring the thread retainer e comes into position to pass through
the loop formed. This is effected by means of a diagonal slot a³ formed in the top
of the framework A in which engages the bar e² secured to the pine and sliding
in a hole e³ in the lever b so that when the vertical lever b is being pressed back
by the sewing needle this slot causes the pin e to be withdrawn to allow the upper
end of the needle threading bar c to pass up with a loop of the thread and as the
vertical lever b returns the said diagonal slot a³ causes the pin e to move inwards

page_text: to engage with the loop of thread formed and hold the thread so that when the
needle is withdrawn as shewn in Figure 4 it is threaded.
In the figures a represents the needle.
A needle threader constructed as described may be made as a separate device
as shewn or it may be fixed to a lady's workbox or table or be combined with a
needle or cotton case.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
First. In a needle threader the combination of a bar or pusher which when the
needle is pressed into the apparatus pushes a loop of thread through the eye of
the needle and a retaining device which engages with the said loop and retains
the thread so that the needle can be withdrawn threaded substantially as herein-
before described.
Second. In a needle threader the combination of the centred lever b and threading
bar c which when the needle is pressed into the apparatus pushes a loop of thread
through the eye of the needle substantially as hereinbefore described.
Third. In a needle threader the combination with means for passing thread
through the eye of the needle of a retaining device e operated substantially as
described to retain the thread so that the needle is withdrawn threaded substantially
as hereinbefore described.
Fourth. In a needle threader in which the thread is pushed through the eye of
the needle by a pusher bar or the like a sliding piece in which the said pusher
bar or the like works so that it can accommodate itself to different descriptions
of needles substantially as hereinbefore described.
Fifth. The arrangement and combination of parts constituting a needle threader
substantially as hereinbefore described and illustrated in the accompanying
drawings.
