A Ventilating Device for Hats.
I, ALEXANDER MELVILLE CLARK, of the Firm of A. M. & Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Chartered Institute of
Patent Agents, do hereby declare the nature of this invention (a communication to
me by G. F. Landauer-Donner, of 59, Städelstrasse, Frankfort-on-the-Main,
Germany, Leather Manufacturer,) and in what manner the same is to be performed
to be particularly described and ascertained in the following statement :-
The present invention has for its object to enable the ventilation of a hat to bo
regulated as desired, and consists of a ventilating device which can be fully opened
or entirely shut as desired. This device is applied to the usual hat leather or sweat
band and is applicable to felt hats as well as to straw hats.
The device consists substantially in providing a series of holes or slits in the hat
leather and also in providing a flap or a sliding piece whereby to close said holes or
to leave them open. For this purpose a second piece of leather or a strip of any
suitable material is combined with the hat leather in such manner as to admit of
being placed in front of the slits, either by turning the strip down on to the slits
or by sliding the strip over the slits, the strip in the latter case being apertured to
correspond to the slits in the hat leather.
Both forms of the device are illustrated in the accompanying drawings. Figure 1
shews the sliding strip piece arrangement, Figure 2 shews the folding flap
arrangement, Figure 3 is a section on the line 1-1 Figure 2.
In Figure 1A is the hat leather or sweat band, which is pierced by a row of
equally spaced apertures or slits a. B is a sliding strip of leather or similar
material which is pierced by corresponding slits b. This sliding piece is applied at
the back of the hat leather and is fastened at one end to a point C of the hat
At its other end the
leather by means of a rubber band or other elastic means c.
sliding piece has an extension d which extends through a slot e to its other side,
that is to say to the side which is situated in the interior of the hat. It terminates
in a ring D or similar device serving for pulling it by and hooking it on to a
button F fixed to the hat leather. When this is done the slits b do not coincide
with the slits a which are then closed, as shewn on the left hand in Figure 1 but if
the ring D be released, the rubber band c will pull the strip B so far as to cause
the slits b to coincide with the slits a. One or more of such sliding pieces may be
arranged on one hat.
In Figures 2 and 3 the hat leather A is perforated in the same manner with
slits a.
But for the purpose of closing said slits a flap G is stitched to the upper
edge of the hat leather A so as to admit of being turned down to close the slits a,
as shewn. In order to open the slits a, the flap is turned up so that it stands upright
inside the hat where it is out of the way.
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
1 L'
fan hote mancisting in the combination with an anortured.

moved or placed as to close said apertures or to leave them open as desired.
2. The particular construction of hat ventilator closing device specified, in which
the closing strip is either itself perforated and capable of being moved laterally or
consists of a flap adapted to be turned down substantially as described.
