An Improved Device for Fitting Needles in Sewing Machines.
I, THEODOR RIEDINGER, of 1 Hirschstrasse, Stuttgart, in the German Empire,
Engraver, do hereby declare the nature of this invention and in what manner the
same is to be perforined, to be particularly described and ascertained in and by the
following statement :-
The subject of this invention is an improved needle inserting device intended
for use in connection with sewing machines and not unlike tongs or nippers in its
construction; its peculiar feature being that, in it, the sewing-machine needle point,
below the eye of the needle and practically the whole of the body or shank of the
needle, are exposed. Owing to this arrangement, the insertion of the needle may
be effected in an easy and reliable manner.
The improved needle-inserting device is shown in the accompanying drawings,
Figure 1. being a side elevation, and
Figure 2. a plan of the same.
Figure 3. shows the front part of the tongs or nippers on an enlarged scale j
Figure 4. is a section on line x x Figure 3.
Figure 5 illustrates the construction of the lower part of that which is shown in
Figure 3, the position of the moveable parts being here modified; and
Figure 6 is a section on line y y Figure 5.
The tongs or nippers mainly consist of two parallel cheeks or jaws b and c,
connected with each other by a U-shaped spring a. The upper cheeks are
slotted, as shown in Figure 2, and provided with two semi-circular recesses 6' 61
facing each other and surrounding the upper portion of the needle d, as shown in
Figure 1, as soon as it is placed in or between the nippers; while the lower end of
the said needle d enters the transverse perforation c in the cheek c, as shown in
Figures 6 and 6. The needle is turned in such a manner that its perforation d' may
receive the point of a pine guided by the longitudinal perforation or bore c² of the
cheek c.
As a needle is inserted, the knob or stud f of the said pin is operated
upon, so that, overcoming the resistance of a spring g, it leaves the path of the
needle d, in consequence of the pressure to which it is subjected (see Figure 5).
When the said stud or knob fis released, the pin e exchanges its position for
that in which it is shown in Figures 3 and 4 and the needle d is firmly fastened in
the nipper device. It is now ready for insertion into the sewing machine. Of
course it is here assumed that the cheeks b and c with the assistance of the set
screw (Figures 1 and 2) are adjusted at such a distance from each other, that
they may enter and fit the space between the needle-bar i (Figure 1) and the
cloth feeding plate (not shown). When once this nipper device or tongs is
adjusted to fit a given machine the eye of each succeeding needle may always
be relied upon, when inserted, to assume exactly the same position in relation to
the said stitching plate. For the removal of the tongs or nippers from the
machine, the knob or stud f should be made to slide back, and then the nippers
sbould be moved down as far as they will go, so as to facilitate the withdrawal of
the cheeks b.
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;-
A needle-inserting dovine for coming machines in the chaos of boucan ninname

page_text: whereby the insertion of a needle, such as d, into the sewing machine is facilitated
by the almost total exposure of the needle, its top end being inserted into one
cheek such as b, which is to be placed against the needle bar from below, like a
clamp, while its lower end reaches into the traverse perforation, such as c' of the
cheek which is placed upon the stitching or cloth feeding plate, so that its spring
controlled pin e, is protected from any longitudinal displacement.
