PROVISIONAL SPECIFICATION.
Improvements in Ventilators for Hats.
I, JOHN VAUGHAN of 9 Barbican London E.C. Gentleman, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved ventilator for hats, and has for its object
to provide a means for more thoroughly ventilating the hat than has been done
heretofore.
This ventilator is placed at the side of the hat, immediately under the bow of
the hat band, and consists of a small flat tube of metal, vulcanite or other suitable
material, open at both ends, one leading into the hat and the other open to the
atmosphere. This tube is completely hidden by the bow, opening close to the end,
so that free access of air is obtained. The tube opens preferably to the front of
the hat, so that in walking a current of air will more readily penetrate to the
interior. The head band in the interior of the hat, is formed in a peculiar manner
being cut, so that, when inserted in the hat, it is of smaller diameter at the top than
at the bottom. A chamber is thus formed all round the hat, into which the air
from the tube passes, causing a more effective ventilation. This band is also
preferably perforated all round at its lower part, where the head meets it, thus
adding to the effect of the ventilation and still further serving to keep the head
cool.
This ventilator may be used alone or in combination with the usual ventilator at
the top of the hat.

COMPLETE SPECIFICATION.
Improvements in Ventilators for Hats,
I, JOHN VAUGHAN, of 9, Barbican, London, E.C. Gentleman, 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:-
This invention relates to an improved ventilator for hats, and has for its object
to provide a means for more thoroughly ventilating the hat than has been done
heretofore.
This ventilator is placed at the lower part of the hat, immediately under the bow
of the hat band or its representative, and consists of a small flat tube of metal,
vulcanite or other suitable material, open at both ends, one leading into the hat and
the other open to the atmosphere. This tube is completely hidden by the bow,
opening close to the end, so that free access of air is obtained. The tube opens
preferably to the front of the hat, so that in walking a current of air will more
readily penetrate to the interior. The sweat band in the interior of the hat is
formed in a peculiar manner, being cut so that when inserted in the hat it is of
smaller diameter at the top than at the bottom. A chamber is thus formed all
round the hat, into which the air from the tube passes, causing a more effective
ventilation.
This band is also preferably perforated all round at its lower part where the head
meets it, thus adding to the effect of the ventilation and still further serving to keep
the head cool.

page_text: This ventilator may be used alone or in combination with the usual ventilator at
the top of the hat.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which
Fig. 1 is a perspective view of part of the hat, showing the bow and the end of
the tube or inlet, and
Figs. 2 to 5 are sections of the ventilator and sweat band.
The hat A is formed with an aperture B in the side, under the hat band at the
part where the bow or equivalent a is placed. A tube C is fixed to the hat, the
outer end of which is open to the atmosphere, the inner end opening through
the aperture so that a passage is formed through the hat.
The tube may be made very short as shown in Fig. 4, consisting simply of a bent
plate forming a passage, opening preferably to the front of the hat. The bow a of
the hat band covers the tube completely, excepting at the open end. The object
of the tube or plate is to keep the passage always open, at the same time partially
preventing the entrance of dust etc., which might otherwise penetrate to the interior,
a small piece of gauze also being preferably employed for that purpose. The tube
or passage may be formed by the bow itself, provided with stiffening material, such
as wire or some stiffening solution. The sweat band D as shown in Figs. 3 and 5
is made narrower at the top than at the bottom, being of truncated conical shape in
Fig. 3 and curved in Fig. 5. A chamber is thus formed all round the head to
The band is preferably perforated as
which fresh air is continually supplied.
shown, at d (Fig. 5) for better ventilation.
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 :-
(1) A ventilating device for head coverings, consisting of a small tube or aper-
ture at the lower part of the hat, opening into the interior and inserted under or
formed by the bow of the band or equivalent, suitably distended, substantially as
and for the purposes described.
(2) A ventilating device for head coverings, consisting of a small tube passing
through the hat, inserted under the bow of the band or equivalent and opening at
its outer end to the atmosphere, substantially as described and shown in Figs. 1, , 2
and 3 of the drawings.
(3) In a ventilating device for head coverings, the said aperture in or under the
bow, communicating with the interior, and opening to the atmosphere at its other
end, being kept distended by a flat tube or stiffening material, the said material
being completely concealed by the bow excepting at the end opening to atmosphere.
(4) In a ventilating device for head coverings, the combination, with an aperture
in the lower part of the hat, of a sweat band made of smaller diameter at the top
than at the bottom, forming an annular chamber around the inside of the hat,
substantially as and for the purposes described.
(5) The ventilating device for head coverings, formed of the tube C opening to
the atmosphere and to the interior of the hat, concealed under the bow a, and the
perforated sweat band D narrowing towards the top and forming a chamber around
the side of the hat, the whole constructed substantially as described and illustrated
in the accompanying drawings.
