IMPROVEMENTS IN SEWING MACHINES
Year: 1872

page_text: LETTERS PATENT to Pierre Marie Joseph Chamblant, residing at
No. 80, Grande Rue de Passy, in the City of Paris, in the Republique
of France, for the Invention of "IMPROVEMENTS IN SEWING MACHINES."
PROVISIONAL SPECIFICATION left by the said Pierre Marie Joseph
Chamblant at the Office of the Commissioners of Patents, with his
Petition, on the 24th August 1872.
I, PIERRE MARIE JOSEPH ⱭHAMBLANT, residing at No. 80, Grande
Rue de Passy, in the Oity of Paris, in the Republique of France, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SEWING MACHINES," to be as follows:-
:-
This Invention consists in substituting for the metal lens shaped
shuttle used in Wheeler and Wilson sewing machines and other similar
machines, a shuttle made of cardboard or other similar substance.
My object is to diminish the weight and the rattle of the shuttle, to
regulate the tension of the thread, to substitute for an expensive article
one of small value, and above all to obviate the necessity for rewinding
shuttles by providing for the workwoman a bobbin of thread in the form
of a shuttle which she can use as she purchases it without any inter-

page_text: mediate preparation. I make the shuttle of two discs of cardboard of
suitable thickness. The discs are stamped so as to dish them and form
a circular cavity in the middle, they are then gummed or cemented
together, and when thoroughly dry the thread is wound upon them.
I make these shuttles to hold a smaller quantity of thread than the
ordinary metal shuttle, and for this reason they work better and they
are so easily changed that no inconvenience results.
In place of cardboard papier maché or other light, cheap, and stiff
material capable of being similarly formed and put together may be
employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Pierre Maric Joseph Chamblant in the Great Scal
Patent Office on the 24th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE
MARIE JOSEPH CHAMBLANT, residing at No. 80, Graude Rue de Passy,

page_text: NOW KNOW YE, that I, the said Pierre Marie Joseph Chamblant, do
hereby declare the nature of the 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, that is to say :-
This Invention consists in substituting for the metal lens shaped
shuttle used in Wheeler and Wilson sewing machines and other similar
machines, a shuttle made of cardboard or other similar substance.
My object is to diminish the weight and the rattle of the shuttle, to
regulate the tension of the thread, to substitute for an expensive article.
one of small value, and above, all to obviate the necessity for rewinding
shuttles by providing for the work woman a bobbin of thread in the form
of a shuttle which she can use as she purchases it without any inter-
mediate preparation. I make the shuttle of two discs of cardboard of
suitable thickness. The discs are stamped so as to dish them and form.
a circular cavity in the middle, they are then gummed or cemented
together and when thoroughly dry the thread is wound upon them.
I make these shuttles to hold a smaller quantity of thread-than tho
'ordinary metal shuttle, and for this reason they work better and they
are so easily changed that no inconvenience results.
In place of cardboard papier-maché or other light, cheap, and stiff
material capable of being similarly formed and put together may be
.employed.
. The annexed Drawings show sewing machine shuttles constructed.
according to my Invention.
Figure 1-is-a side view, and Figure 2a section; Figure 3 is also a.
side-view showing a shuttle with a central hole.
What I claim is the construction of that part of a sewing machine
called the shuttle, substantially as described.
In witness whercof, I, the said Pierre. Maric- Joseph Chamblant,
have liereunto set my hand and scal, this Nineteenth day of
February, in the year of our Lord One thousand eight hundred
and seventy-three.
