Improved Method of and Means for Ventilating Hats.
.
GEORGE HERBERT DIXON, The Constitutional Club, Northumberland Avenue,
London, Gentleman, do hereby declare the nature of this invention to be as follows:-
A narrow oblong frame with hollow grooved edges, and having a horizontal
aperture in the middle thereof, is fixed into the sides of the hat opposite each other;
at a height of about one-half inch above the rim or edge. To this frame on the
inside of the hat a hollow shaft is affixed and carried up to about two inches, being
closed at the sides and, at the bottom, beneath the frame. The incoming cold air is
thus carried above and does not come in immediate contact with the scalp. At the
top of the shaft a lid is placed which can be partially or wholly closed or opened at
the will of. wearer so as to regulate the temperature in the hat while being worn.

I, GEORGE HERBERT DIXON, The Constitutional Club, Northumberland Avenue,
London, 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 the ventilation of hats by means of an appliance which I
shall describe referring to the accompanying drawings. Fig. 1 is a vertical section
Fig. 2 is a front view and Fig. 3 is a sectional plan, of one side of a hat, shewing the
appliance according to my invention. Between the side A of the hat and the lining B
I form a thin vertical channel C which opens outside with a rectangular mouth D
just above the band at the brim and extends up some distance inside the hat so
-as-to-have-a-top-opening-into-the-upper part of tho hat above the head of the
wearer. By this channel-fresh air from outside can enter, heated air passing away by
an aperture or apertures in the crown, or, there being a channel at each side of the
bat, fresh air can enter by the one and heated air pass out by the other. I prefer to
fit a hinged lid at the upper mouth E of the channel so that by closing it more or less,
the current of air can be regulated. The channel may be made of thin sheet metal,
cardboard or the like attached by cement or otherwise to the interior surface of the
hat;
and the lid at E, instead of being hinged, may be merely a piece of the material
which forms the channel extended upwards so that it can be bent more or less
according as the mouth is desired to be more or less closed or opened.
The channel may be divided and strengthened by a vertical partition extending up
its middle as indicated by the dotted lines F.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
For ventilation of hats, the use of a thin vertical channel extending up within the
hat from a mouth opening outside near the brim to an adjustable mouth opening
inside above the head of the wearer, substantially as described.
Dated this 13th day of December 1888.
