Improvements in Needle Threaders.
I, HENRY MARION CHILDERS, of Oregon Street, Ontario, in the County of
Malheur and State of Oregon, U.S.A., Farmer; 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 :-
My invention relates to certain new and useful improvements in needle threaders
for sewing machines, the object of the same being t provide a simple and cheaply
constructed device of this character by means of which the needle of the sewing
machine may be readily and conveniently threaded even by persons of poor
eye-sight.
The invention consists of a block having a cut-away portion on its under side
permitting it to straddle the presser foot of a sewing machine, a cut-away portion
on its upper side forming a shoulder at one end, and a tapering cone-shaped slot
extending laterally therethrough having an extension at one side leading outwardly
through said shoulder.
The invention is clearly illustrated in the accompanying drawings, in which,
Figure represents a perspective view of a sewing machine, showing the
application of my improved threading device thereto.
Figure 2 is a detail perspective view on an enlarged scale of the threader.
Figure 3 is a vertical central longitudinal section through the same.
Figure 4 is a top plan view, and
Figure 5 is a horizontal sectional view through the tapering opening therein.
Like reference numerals indicate like parts in the different views.
My improved threader is made up of a block 1 of metal or other suitable material
having its under side cut away as shown at 2 forming legs or supports 3, 3 upon
which said block is adapted to rest and permitting the same to straddle the presser
foot 4 of the sewing machine 5. The upper side of the block 1 is cut away at one
point forming a shoulder 6 and a lug or extension 7 thereon. Extending through
the lug 7 is a tapering cone-shaped opening 8 which terminates at a point adjacent
to the shoulder 6 and has a slit 9 leading thereinto through the lug or extension 7.
A vertically disposed recess 10 adapted to receive the lower end of the needle 4
is formed in the top surface of the block 1 adjacent to one side of the
shoulder 6.
In using my device the block 1 is applied as shown in Figure 1 of the
drawings, and the needle 4 is lowered so that the point thereof fits within the
recess 10. The said needle is moved until the eye therein lies directly opposite
the small end of the tapering opening 8. The thread is then free to be passed
through said opening and through the eye of the needle, being guided in its course
by the inclined sides of said tapering opening. When inserted in the eye of the
needle the thread may be withdrawn from the slot 8 through the slit 9 leading
thereinto. The needle 4 is then moved out of the recess 10 and the block 1 is
removed.
The device is extremely simple in construction, can be cheaply inade, and is
effective for the purpose for which it was designed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A needle threader, consisting of a block having a tapering opening therein
through which the thread is adapted to be passed, substantially as described.

page_text: 2. A needle threader, consisting of a block having a tapering opening therein
through which the thread is adapted to be passed, and means for holding the needle
so that the eye thereof will lie directly opposite the small end of said tapering
opening, substantially as described.
3. A needle threader, consisting of a block having a tapering opening therein
-through which the thread is adapted to be passed, a laterally extending slit leading
into said opening and means for holding the needle so that the eye thereof will lie
directly opposite the small end of said tapering opening, substantially as and for
the purpose described.
4. A threading device for the needles of sewing machines, consisting of a block
having a lug upon the upper side thereof forming a shoulder between it and the main
portion of said block, a tapering opening extending through said lug and terminating
at a point adjacent to said shoulder, a slit extending through said lug into said
opening, and a recess for receiving the point of the needle located in the upper side
-of said block adjacent to the contracted end of said opening, substantially as and
for the purpose described.
