page_text: A Proved at ventilator.
I, JOHN NUTSFORD, of 26, Bank Street, Carlisle, Cumberland, Hairdresser, do
hereby declare the nature of this invention to be as follows:-
My invention is a novelty for securing free and effective ventilation of the
hat keeping the covered part of the head perfectly cool and preventing baldness.
It consists of a ventilator for felt hats or any kind of hat and may be composed
of celluloid, vulcanite, paper mache, metal, or any other material. It is affixed
between the inner band and the hat. The outer apertures (A) for admission of
air into the hat may be circular or elongated, and may be varied in number and
size as required. The air passes through the outer apertures into the hat by
means of the inner aperture (E) and between the plates (B and C). The air
circulates about the head and escapes by an outlet at the top of the hat. The
two plates are conected by the side plates (D) and the whole form one piece.

I, JOHN NUTSFORD, of 26, Bank Street, Carlisle, Cumberland, Hairdresser, 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;-
-
My invention consists in a ventilator for hats constructed and capable of appli-
cation to hats as hereinafter described with reference to the accompanying
drawing.
Figures 1, 2 and 3 of the said drawing are respectively a face view of the
ventilator a view of the upper side thereof and a section of the same taken on
the line A Figure 1. The said ventilator as illustrated by the said figures con-
sists of a pocket shaped part a closed at bottom and at its ends and having a
tubular mouth in one of its sides or faces for inlet of air and open at its upper
part to admit of exit of air at the said part.
The manner in which I prefer to apply the ventilator to a hat is illustrated
in Figures 4 and 5 in which figures a portion of a felt hat of ordinary shape with
the ventilator in place therein is represented in side view and transverse section
respectively. The position of the ventilator as shown by the said figures is be-
tween the body portion c of the hat and the lining band d in which position the
CD 77

page_text: ventilator is secured by engagement of the tubular mouth b in a hole in the
said body portion. The arrows in the said Figure 5 show the direction in which
air passes through the ventilator into the hat when on the head. The air so
entering the hat circulates about the head and escapes by an outlet at the top
of the hat which outlet is illustrated at e in Figure 5. The said outlet may be
an ordinary eyelet shaped ventilator and constitutes no part of my invention.
Figures 6, 7 and 8 are views corresponding to Figures 1, 2 and 3 and illustrating
a ventilator constructed according to my invention and provided with two inlet
mouths of circular form.
Hat ventilators constructed according to my invention are applicable to any
kind of hats and when secured within hats as illustrated in Figures 4 and 5
admit of free passage of air to the interior thereof and are not liable to obstruc-
tion when the hats are being worn. The said ventilators may be made of celluloid
vulcanite papier-mache metal or any other material sufficiently stiff to prevent
closure of the air passages of the ventilators during ordinary use of hats to
which they are applied.
My invention is not restricted to construction of the ventilators of the precise
shape or relative dimensions illustrated nor to any number size or shape of the
air inlets as these details may be varied without departing from the nature of
my said invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
An improved hat ventilator constructed substantially as hereinbefore_described
and illustrated in the accompanying drawing that is to say a hat ventilator con-
sisting of an approximately flat pocket shaped part adapted to be conveniently
secured between the interior of the body of a hat and the lining band and having
on one side an air inlet mouth or air inlet mouths capable of being engaged
in a hole or holes in the body part of a hat so that air may enter the said mouth
or mouths from without the hat and also having an opening from which when
the ventilator is in place in a hat air entering by the inlet mouth or mouths
may pass freely into the interior of the hat and without liability to obstruction
when the hat is being worn.
