AN IMPROVED VENTILATING HAT
Year: 1869

page_text: LETTERS PATENT to Jules Garde and Adolphe Garde, both of Bor-
deaux, and of 37, Boulevard Bonne Nouvelle, Paris, in the Empire
of France, for the Invention of "AN IMPROVED VENTILATING HAT."
Sealed the 28th January 1870, and dated the 6th August 1869.
PROVISIONAL SPECIFICATION left by the said Jules Garde and
Adolphe Garde at the Office of the Commissioners of Patents, with
their Petition, on the 6th August 1869.
We, JULES GARDE and ADOLPHE GARDE, both of Bordeaux, and of 37,
Boulevard Bonne Nouvelle, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "AN IMPROVED VENTILATING
HAT," to be as follows:-
Our improved ventilating hat, in addition to the continuous venti-
lation effected between the body and the leather or its inside lining, as

page_text: shown, Fig. 3, of the annexed Sheet of Drawing, affords the following
advantages :-
1°. Imperviousness to perspiration by reason of the ventilating space
(A, Fig. 3), which separates the forehead from the body of the hat.
2°. The ventilation being obtained by a series of eyelet holes or
openings made under the brim (see Figs. 3 and 4) it cannot in any way
lessen the wear or the strength, nor interfere with the comformation of
the hat.
.
3°. The holes made under the brim of the hat and those made in the
crown give a continuous supply of air.
4°. This kind of hat may be made extremely light and durable with
elegance of shape.
This method of ventilation may be applied to military head gear
without increase of price or size,
DESCRIPTION OF THE DRAWING.
Fig. 1 is a front view of one of our ventilating hats, showing no trace
of opening above the brim; Fig. 2, side view of same, presenting no
greater bulk than an ordinary hat.
Fig. 3, side view of hat in section through the centre at A, B, Fig. 4.
A, space,
in which the ventilators are placed, establishing a current of
air circulating from A, B; C, ventilator placed on the crown of the hat;
B, the lining.
Fig. 4 shows the interior of the hat, the under side of the brim
displays the ventilating eyelets of the curve traversed by the line
C, D. This Figure also shews the ventilator placed at the bottom of
the hat,
Fig. 5, exterior of hat looking on to crown. In this position no
ventilator is visible, excepting that in the crown of the hat those of
the brim not appearing on its upper side.
We would observe that the ventilator placed in the crown may be
dispensed with when a very free circulation of air is not desired. This
kind of hat may be made of any kind of material used for hat making
and is even applicable to straw hats of every shape and make.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jules Garde and Adolphe Garde in the Great
Seal Patent Office on the 2nd February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JULES
GARDE and ADOLPHE GARDE, both of Bordeaux, and of 37, Boulevard
Bonne Nouvelle, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of August, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Jules Garde and Adolphe Garde,
Her special licence that we, the said Jules Garde and Adolphe Garde,
our executors, administrators, and assigns, or such others as wc, the
said Jules Garde and Adolphe Garde, our 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 "AN IMPROVED VENTILATING HAT,"
upon the condition (amongst others) that we, the said Jules Garde
and Adolphe Garde, our executors or administrators, by an instrument
in writing under our, or one of our, their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, 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 we, the said Jules Garde and Adolphe Garde,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Sheet of Drawing and to the figures and letters of reference
placed thereon:-
Our system of ventilating hat, in establishing a continuous venti-
lation, which is effected between the body and the leather or inside

page_text: lining, as shewn, Fig. 3 of the Drawing, affords the following ad-
vantages:-
1°. Imperviousness to perspiration by reason of the space A (Fig. 3),
which separates the forehead from the body of the hat, and in which are
placed the ventilators (C, D, Fig. 4).
2°. The ventilation being obtained by a series of eyelet holes or
openings F made under the brim (see Figs. 3 and 4) between the leather
and the body, it cannot in any way lessen the wear or the strength,
nor interfere with the comformation of the hat.
3°. The holes made under the brim of the hat and those made in
the crown give a continuous supply of air, preventing the perspiration
always occasioned by want of air, when, as in ordinary hats, it cannot
be renewed.
4°. This kind of hat may be made extremely light and durable with
elegance of shape.
This method of ventilation may be applied to military head gear
without increase of price or size.
DESCRIPTION OF THE DRAWING.
Fig. 1 is a front view of one of our ventilating hats, showing no trace
of opening above the brim; Fig. 2, side view of same, presenting no
greater bulk than an ordinary hat.
Fig. 3, side view of hat in section at A, B, Fig. 4. A, space in which
the ventilators are placed, establishing a current of air circulating from
A to B; C, ventilator placed in the crown of the hat. This ventilator C
is not claimed as novel. B, the lining or leather band.
Fig. 4 shews the interior of the hat, looking down upon it. The
under side of the brim displays the ventilating eyelets of the curve
traversed by the line C, D. This Figure also shews the ventilator placed
at the bottom of the hat.
Fig. 5, exterior of hat, looking on to crown. In this position no
ventilator is visible, excepting that in the crown of the hat, those of the
brim not appearing on its upper side.
We would observe that the ventilator placed in the crown may be
dispensed with when a very free circulation of air is not desired. This

page_text: description of hat may be made of any kind of material used for hat
making, and is even applicable to straw hats of every shape and make.
Claim is made to the exclusive use in their application to hats of
every shape and of any material, of ventilators formed by an indefinite
number of eyelets covered with any inoxydizable substance, and placed
under the brim of the hat, the ventilation penetrating to the interior,
either simply between the leather band with which the inner circum-
ference of the hat is lined, and which is also provided with similar
eyelet holes, or into a channel formed inside between the body and the
leather band, producing therein a constant circulation of air.
In witness whereof, we, the said Jules Garde and Adolphe Garde,
have hereunto set our hands and seals, this Twenty-seventh day
of January, in the year of our Lord One thousand eight hundred
and seventy.
