Apparatus for Stitching Documents, Copy-books, and Business-books
with Thread.
We CARL SCHROTZ, Manufacturer of Deutz near Cologne and CARL SCHOLZ,
Manufacturer of Deutz near Cologne in the Province of Rhineland and Kingdom
of Prussia 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 :-
In the drawing
Fig. 1 represents the apparatus in a longitudinal section, Fig. 2 the cross-section
on the line W-X, Fig. 3 the cross-section on the line Y-Z, the spool being taken
away, so that the ratchet-wheel i may become visible.
Figure 4 shows the formation of the thread in a set of documents stitched by the
apparatus.
Fig. 5 and 6 are auxiliary parts in the production of the loops of the thread,
Fig. 5 is a needle, which is used in stitching ordinary documents, when only a
single thread is used; Fig. 6 is a kind of shuttle as in sewing-machines, containing
a thread-spool and applied in the stitching of business-books, when the stitching is
done uninterruptedly with two threads.
The box a serves to receive the thread spool b and is at the same time a handle.
On the part e of the box a there are two perforations, a central one d, which
receives the needle f, that is held fast by a set-screw e, and a second one g, to one
side of d, through which the stitching thread is carried from the interior of the
box a to the outside.
The hand-wheel h, visible on the outside at one end of the box and attached to
the axle of the spool, serves to wind the thread up again, that may have rolled off
too much in the making of the knots, while the ratchet-wheel i has the object of
letting the thread only run off slowly and with a certain amount of tension, and to
hold the spool fast, when the thread is pulled tight.
The case k, visible in Fig. 1 and screwed on to serves to cover and protect the
needle, when the apparatus is not being used; by the help of it the apparatus
may be laid down anywhere and even put into one's pocket.
In the stitching of ordinary documents, manuscripts and copy-books, when only
a single thread is used, the apparatus is used in the following manner :
After the case K has been screwed off from c, the end of the thread is drawn
through the eye of the needle f, the fold of the gathering 1 (Fig. 4) is pierced by
the needle at from the inside and thereupon the apparatus is drawn somewhat
back towards the inside, so that the thread forms a loop on the outside in front of
the back of the paper. Then the hook p (Fig. 5) is taken and hooked through the
loop in such a manner, that the end of the thread is held fast in the loop; then
the thread is drawn out the length of the paper, that is to be stitched. Then the
needle fis drawn out with the apparatus entirely out of the perforation m and the
fold is once more perforated at n and at o (or in as many places as is desired) the
end of the thread q being drawn through the loops formed on the outside at n, o,
by means of the hook, which now serves as a guide-needle.
Finally the hook is removed from the end of the thread, and the latter drawn
together with the loop last formed (at o) towards the inside, where the final-knot is
then made.

page_text: The process is quite the same in stitching business books, when the separate
gatherings are cut in for a certain length in the fold at the edge, two threads being
then used, one on the inside in the fold and one at the outside at the back of the
paper, and the threads not being cut off after each separate gathering has been
stitched, but being used continuously for the stitching of the following gatherings.
In order to be able to work with two threads, while using the apparatus in
question, the apparatus is then only used to form the inside thread, and instead of
the hook p, the shuttles, represented in Fig. 6 and containing a spool of thread
is used, which then supplies the outside thread.
The process is as follows:
After the loop of the inside thread has been formed on the outside in the first
gathering at the end of the first cut with the needle f, the shuttle s is put through
the loop and the latter is pulled tightly over the end of the outside thread, lying in
it and coming from the shuttle s. The outside thread may also be knotted.
Thereupon from the inside the other perforations are made with the needle f
from the inside, the loops being made on the outside, the shuttle s is each time
passed through the loops, the latter are pulled tightly and when the last uppermost
loop at the upper cut in the first gathering has been formed, the apparatus is used
at the inside of the next gathering, first of all at its upper cut. The shuttle s is
then again put through the loop thus formed, and the apparatus and shuttle used
downwards as far as the lower cut, from here to the lower cut of the third gathering,
then in an upward direction along it, continuing in this manner, until all gatherings
are stitched."
The little wheel t on the axle of the spool in the shuttles serves for winding
up again any thread, that may have been unwound too much, and to hold the spool
fast, when the thread is drawn tight.
When the apparatus is not in use, the hook p, which otherwise might easily be
lost, is placed on the outside of the box a or the case in a little tube specially
provided for it or in a suitable clamp, or it is placed in a third hole in the part e,
and then also covered by the protecting case k, which is screwed over the needle f.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. An apparatus for stitching documents, copy-hooks and business-books with
thread, consisting of the box, containing the Spool of thread 6 and the ratchet-
wheel in the inside, and the needle with protecting-case and the hand wheel h
on the outside.
2. As auxiliary part to the stitching apparatus the hook p
گاه
3. As auxiliary part to the stitching apparatus the shuttle containing a spool
for thread in the interior, and provided in front with a point a and at the back
with a little hand-wheel t.
