PROVISIONAL SPECIFICATION left by the said Louis Victor André
at the Office of the Commissioners of Patents, with his Petition,
on the 7th September 1871.
I, LOUIS VICTOR ANDRÉ, of 2, Rue Ste. Appoline, in the City of
Paris, Mechanician, do hereby declare the nature of the said Invention
"IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES FOR SEWING MACHINES,"
to be as follows:-
for
The object of this Invention is entirely to do away with the threading
holes in shuttles for sewing machines, and hence also with threading,
generally long and difficult, and using thread to no purpose. My system
has also the advantage of rendering the shuttle lighter.

Fig. 7 shows the spool which, because of the interior construction
of this shuttle, contains about 20 per cent. more thread than any other
of equal length. The spool holder or shield (Fig. 7) from its length,
and from its receeding from the inside of the shuttle, allows the thread to
free itself with the greatest regularity, whatever the position of the same,
either at the centre or at the ends. Fig. 2 shews the slot.b for the
exit of the thread from the shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Victor André in the Great Seal Patent Office
on the 7th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Louis
VICTOR ANDRÉ, of 2, Rue Sainte Appoline, in the City of Paris,
Mechanician, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of September, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Louis Victor André, Her special licence,
that I, the said Louis Victor André, my executors, 'administrators, and
assigns, or such others as I, the said Louis Victor André, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the 'term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS. IN

page_text: THE CONSTRUCTION OF SHUTTLES FOR SEWING MACHINES," upon the condition
(amongst others) that I, the said Louis Victor André, my executors or
administrators, by an instrument in writing under my, or their, or 'one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Louis Victor André, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof reference being had to the accom-
panying Drawings, and to the figures and letters marked thereon,
that is to say:
I
My Invention consists in the suppression of threading holes in the
shuttles for sewing machines; because it is known that the threading is
long and difficult, and that the usual dispositions wear out the thread to
no purpose.
What characterizes my improvements is that the thread which is
engaged in the restraining clements of the shuttle, by making it slide
between small metal plates acting as springs, passes into special
notches, where it is directed and maintained by notches as well and even
better than if the thread was passed through the holes employed until
this day in the shuttles for sewing machines, and finally, this arrangement
of the thread in requisite conditions in the shuttle is made with great
facility and instantly.
The Drawing hereunto joined shows the shuttle with my improvements.
Fig. 1 is a front view of the shuttle with all its different pieces.
Fig. 2 shows the interior of the shuttle on the side of the exit of the
thread, and Fig. 3 is a view of the opposite side.
Fig. 4 shows three projections of the shuttle latch; a front view, a
side view, and an end view.
Fig. 5 shows two views of the tension spring, front and profile view.
The body a of the shuttle keeps the usual forms and dispositions as
shown on the Drawing hereunto joined; it receives internally a spring f
welded at one end only on the side of the hole, which allows the exit of

page_text: of the thread replaces the threading by the shuttle holes. In fact, it is
understood that this passage is double, since after having passed between
the little spring and the tension spring the thread passes between
another spring and the interior of the shuttle. Definitely it gives the
same results as the threading, without having its inconveniences, that is
to say, very notable economy of time and painstaking care, whilst
avoiding any alteration of the thread at its exit from the shuttle.
In witness whereof, I, the said Louis Victor André, have herunto set
my hand and seal, this First day of March, in the year of our
Lord One thousand eight hundred and seventy-two.
LOUIS VICTOR ANDRÉ. (L.S.)
