COMPLETE SPECIFICATION.
Improved Means for Ventilating Hats.
I, WILHELM KARL, Pastor, of Egringen in the Grand Duchy of Baden,
German Empire, do hereby declare the nature of my invention and in what manner
the same is performed to be particularly described and ascertained in and by
the following statement :-
The present invention relates to means for ventilating hats and its object is to
obviate the unpleasantness caused to the head by the leather lining at present
generally employed in connection with silk, felt and other hats, and also to provide
for a more adequate ventilation of the head than hitherto. The perforations at
present employed in the crowns and sides of hats do not by any means provide
sufficient ventilation for the head and the leather bands used inside the hat and
fitting closely onto the head cause an unhealthy perspiration of the latter, the
moisture thus produced is not able to escape and consequently is retained in the
crown of the hat and exercises a depressing influence on the nerves of the head.
By the present invention means are provided to ventilate the head and hat all
round, and at that point where the hat fits onto the head.
And in order to make this Specification more easily intelligible reference is had
to the accompanying drawing in which similar letters denote similar parts through-
out the several views,
Fig. 1 being a horizontal section through the crown of a hat along the line x x
Fig. 2,
Fig. 2 a vertical section through the hat and
Figs. 3 and 4 detail sections showing the arrangement of the ventilator in two
modifications.
The hat A instead of being provided with a full leather lining has a perforated
band barranged inside to close onto the head and between this band and the hat is
located a vertically perforated rubber or cork ring a of about one eighth of an inch
more or less in thickness. These hats will not fit tightly onto the head causing an
undue perspiring of the same, but the perforations c of the lining band will allow
any moisture to be evaporated and pass into the hat whence it will be removed by
the continual air circulation through the vertical perforations f of the ring a
escaping, in the case of straw hats through the interstices of the same, in felt hats
through the ventilator d.
In the modification shown in Fig. 4 instead of employing a continuous band or
ring a extending round the hat, small pieces of cork or rubber a' are arranged
round the inside of the hat having suitable intervals fl between them, said
pieces a¹ being arranged between the hat and the lining b. Fig. 3 is a detail view
showing the arrangement as described with reference to Figs. and 2, the band a
having perforations f and being inserted between the hat A and the lining b
having perforations c.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
:-
In hats the arrangements of a perforated lining ring b and an intermediate ring a
of cork, rubber or other suitable material and having perforations fin the manner
and for the purpose substantially as described.
