Improvements in or relating to Head Coverings.
I, LUDWIG HINTZE, of 43 Augustinerstrasse Ertfurt, in the Empire of Germany,
Bandmaster of the 71st. 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 a head-covering such as a cap hat or the like which is
provided with an air-cushion.
In the accompanying drawing is shown, by way of example, a military cap accord-
ing to the present invention, Fig. 1 being a section and Fig. 2 a detail view. Figs. 3
and 4 show a modification of the invention.
Between the lining a and the top of the cap 6 there is placed an air-cushion c made
preferably of elastic material which can be inflated to the desired extent through a
valve d passing through the lining or cap.
When it is desired to use the head covering according to the present invention as
a cushion or seat, the air-cushion c is fully inflated to the position I. If it is desired
to use it as a pillow, it is sufficient to inflate it to the position marked II.
The head-covering may of course be of any desired form and size, and the air-
cushion c is formed to suit its shape. The air-cushion c may also in many cases he
constituted either directly by the lining a and the top b (Fig. 3) or by two layers of
lining a (Fig. 4) by making these parts of air-proof material, making their joints
air-tight and providing them with an air-valve of any desired construction, in any
desired suitable position on the head covering.
The head covering described offers great advantages to travelling and military
people as it can be filled with air to the position II and then used as a head rest or
cushion or as an ordinary pillow and can be carried about in the pocket when deflated
and folded as an ordinary travelling cap.
For military people the head-covering according to the present invention is
especially convenient in manoeuvres for instance when bivouacking, as a pillow. In
case of illness or wounds etc. the air-cushion c arranged between the top 6 of the cap
and the lining may be removed and filled with ice or cold water and used as a
compress. In this case the lining a is inade detachable on one side to enable the
cushion c to be conveniently removed or re-introduced. The arrangement of the
valve d, may be such, for instance, in military caps, as to project outside or through
the central portion f of the badge k, which may thus form the cap for the
valve (Fig. 2). Of course any caps as well as soft hats etc. can be provided with such
air-cushions, the valve d being arranged in any desired position.
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:-
°
1. A head-covering provided with an air-cushion or bag made of some elastic
material arranged between the lining and the top of the head-covering, which
cushion or bac when inflated to a desired extent through an air-valve arranged in

page_text: any desired position inside or outside the cap, can be used as pillow, seat or cushion,
or when filled with cold water or ice as a compress in case of illness, substantially as
described.
2. A head covering provided with an air-cushion formed by the lining a and the
top 6 of the cap or by two lining layers a of air-proof material the joints being made
in an air-tight manner said parts being provided with an air-valve of any desired
construction substantially as described.
3. The combination and arrangement of parts constituting the complete head
covering substantially as described and illustrated in Fig. 1 or in Fig. 3 or in Fig. 4
of the accompanying drawings.
