PROVISIONAL SPECIFICATION.
An Improved Ventilator for Hats and Caps.
I HENRY FREDERICK FREUTEL of 133 and 135 Kingsland Road, E. Cap
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved ventilator for hats and caps, the improve-
ment being more particularly, although not exclusively, applicable to soft caps of
tweed and the like which are frequently carried in the pocket.
The improved ventilator is introduced between the sweat band and the body, and
the object of the improvement is to so make the ventilator as to enable it to
withstand without injury the crushing and folding to which-it is subjected.
The improvement consists in making the ventilator of a gauffered or corrugated
band of a stiff or stiffened fabric which when applied between the sweat pad and
the body will maintain them at a certain distance apart and afford numerous
channels for the admission of cool air the corrugations opening out at the lower
ends below the peak or brim, and at the upper ends to the interior of the hat or
cap. The fabric employed is for the sake of lightness preferably of an open
character such as buckram or horsehair and cotton or fibre and cotton cloth such
as used for hat linings suitably stiffened if necessary to enable it to preserve its
corrugated form, or even of fine wire gauze. The material is corrugated by passing
it through the ordinary gaufring rollers and is secured in position between the sweat
band and body by stitching.
Dated this 10th day of April 1893.

COMPLETE SPECIFICATION.
An Improved Ventilator for Hats and Caps.
I, HENRY FREDERICK FREUTEL of 133, and 135, Kingsland Road, E., Cap
Manufacturer, 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 relates to an improved ventilator for hats and caps, the improve-
ment being more particularly, although not exclusively, applicable to soft caps of
tweed and the like. The improved ventilator is introduced between the sweat band
and the body, and the object of the improvement is to so make the ventilator as to
enable it to withstand, without injury, the crushing and folding to which it is
subjected when carried in the pocket.
The invention is illustrated in the accompanying drawings, forming part of this
Specification, as applied to a soft cap.
Figure 1 represents the cap in section, shewing the ventilator in position.
Figure 2 is an underside view of the cap, with the sweat-band partly broken
away to shew the ventilator.
Figure 3 is a perspective end view of a portion of the ventilator, separately
drawn.
The same letters of reference denote like parts in all the figures.
The improvement consists in making the ventilator a of a gauffered or corrugated
band of a stiff or stiffened fabric which when applied between the sweat pad b and
the body c of the cap will maintain them at a sufficient distance apart and afford

page_text: numerous channels d for the admission of cool air, the channels opening out at the
lower ends below the peak or brim and at the upper ends to the interior of the hat
or cap. The fabric employed is, for the sake of lightness, preferably of an open
character, such as buckram or horsehair and cotton cloth or fibre and cotton cloth
such as used for hat linings and wherein the horsehair or fibre constitutes the weft,
and the cotton the warp, of the fabric, the fabric being suitably stiffened by
impregnating the cotton with some starchy matter, if necessary, to enable it to
preserve the corrugated form. Fine wire gauze may however be used.
In order to avoid presenting a raw or jagged edge below the sweat pad, the
strip of material before being gauffered or corrugated is folded upon itself
longitudinally and the doubled strip is then transversely corrugated by passing it
between the rollers of an ordinary gauffering machine. The guaffered or
corrugated strip is then secured in position by stitching it at intervals to the
body of the cap, and is then covered by the sweat band which is stitched thereto.
In conjunction with this improved ventilator, it is preferred to use the ventilating
lining for the crown of the cap described in the Specification of previous Letters
Patent granted to me dated the 6th day of April 1892, No. 6633-which affords a
ready outlet for the warm air, whilst the channels or corrugations admit a copious
supply of cool fresh air to replace the warm air.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
The herein described ventilator for hats and caps consisting of a corrugated or
gauffered strip of a stiff or stiffened fabric inserted between the body and the
sweat band, substantially as specified.
Dated this oth day of May 1999.
