3 Claims. (cl. 2223-99)
‘This invention relates to appliances for facili
tating the work of hand sewing and more particu
, larly to needle threaders.
The main object of the invention is to provide
5 a device by which any common sewing needle
may be assuredly and easily threaded with suit
able thread, the same being passed through the
eye of the needle in a positive manner.
A further feature is in the provision of means
‘ 10 whereby the needle to be threaded is automatically.
‘ adjusted into position to receive the thread when
fully entered into the device.
Another purpose is to produce a. needle threader
by the bight 23 the showing of the curve in Fig
ure 1. being exaggerated.
A common sewing needle 25 provided with a
?attened head 26, containing the eye 22, is en
gaged, when fully entered into the threader, in 5
a rectangular aperture ‘28 formed in the solid base
29 of they circular opening to receive the needle.
In operation, the needle iszentered so that its
head is seated in thesocket 28, whereby the eye
22 is alined and caused to register with the 10
opening l3 between the spaced walls of the
threader.

Thereafter
the slide H is pressed inwardly until
I
the pin 2c limits its movement. The loop 2!
convenient to operate, even by unskilled persons,
5 and which is small and compact, forming a use ' passes through the needle eye, the opening it ‘and 15
ful adjunct to- the appliances usually employed by
a seamstress.
These desirable objects are accomplished by
the novel and practical construction and com~
20 bination of simple parts hereinafter described and
illustrated in the accompanying drawing con
stituting an essential component of this disclosure‘
and ‘in which: '
Figure 1 is aisid'e elevational view of an em
25. bodiment of the device.
Figure 2 is a central longitudinal sectional view
of they same, parts beingshown in another posi
tion.
'
~
Figure 3 is'a transverse sectional view taken on
30 line 3-3 of Figure 1.
,
li'igure'4 is a further enlarged fragmentary
' sectional view showing the needle receiving socket.
Referring in- greater ‘detail to the drawing, the
main part of the device, designated by thenu
, 35 ‘meral It), consists of a narrow casing, generally
a truncated triangle, its outer, smaller end being
open and its‘ closed, opposite, or base end J2
curved semi-cylindrically by folding the thin
plate constituting the side walls and provided
with a perforation l3 in the extreme portion of
the curved closure near its bottom.
‘Engaged around this curved element is a forked
socket M from which projects a sheath i5, closed
45 at its outer end and having‘ a transverse opening
i6 alined with the perforation IS.
?nally presses its bight 23 against the curved
outer wall of the element 15 causing the loop to .
expand, as best seen in Figure 2; thereafter a ~‘
thread 30 is entered through‘th'e opening 16, and,
obviously also the loop 2i thus expanded. ,
20.
Upon drawing-the slide outwardly, the thread
30 is‘ drawn through the eye of the needle, com
pleting the threading, operation, whereupon the
needle may be withdrawn, ready for use.‘
'
_,
It is to‘be understood that the sheath i5 may 25
be'omitted and/the loop 23 expanded by pressure,
as' fromv an operator’s ?nger, thus providing _
means for threading a sewing machine needle,
'the operation of which will be apparent.
Although the foregoing is descriptive-of the pre-_ 30
ferred embodiment of the‘ inventor, it will be
apparent that minor changes may be made in its
construction, without the exercise of invention or
con?icting with the scope ofethe claims hereto
appended.

Having thus described the invention, what is
claimed-‘as new anddesired to secure by Letters Patent, is:

1. A needle threader comprising a thin, ?at
casing adapted to receive the shank of a needle 40
upright therein, means to compel the eye” of the
needle to aline with the space between the walls
of said casing,‘ a spring loop guided by the casing
walls to pass through the\needle eye, a closed
sheath on said casing to expand said loop after 45
A slide [7, provided with a lip i8 to act as a _ passing through the eye to receive a thread, and
handle, contains a central longitudinal slot 89 manual means for actuating said loop to cause

50 casing I 0, 'being limited by a pin 20 at either
its expansion.’
