An Improvement in Hats.
We, WILLIAM COWPER ROBISON, Sheep Farmer, CHARLES LLOYD GARDINER,
Gentleman, and THOMAS HENRY REGINALD GARDINER, Sheep Farmer, all of
54, Lambton Quay, Wellington, New Zealand, do hereby declare the nature of
this invention, to be as follows:-
This invention relates to hats, its object being to provide means for relieving
certain parts of the head from the pressure of the hat.
We have discovered that pressure of the hat upon the temporal arteries and
veins or their main branches arrests the free circulation of the blood in the scalp.
and causes baldness. Such pressure occurs only in the case of persons whose
skull has a fullness or convexity where the aforesaid arteries and veins are inter-
sected by the rim of the hat, whilst with persons who in such part of the skull
have a depression or concavity there is no injurious pressure of the hat and bald-
ness does not ensue.
Our invention is carried into effect by making the hat in any ordinary form but
we provide pads attached to the rim on its interior so that the hat and pads fit
the head excepting where the rim crosses the aforesaid arteries and veins. The
rim is thus held from touching the head of the wear near or where the pads are
interrupted, and the blood is thus allowed to flow freely.
The pads may be made of inflated india rubber, cork, felt, leather, or other
suitable material or combination of materials.
Instead of using pads, we may shape or block the hat with recesses or out-
ward depressions in the rim where the same passes over the aforesaid arteries
and veins.

page_text: 54, Lambton Quay, Wellington, New Zealand, 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 hats and has for its object to provide a means for
relieving certain parts of the head from the pressure of the hat. We have dis-
covered that pressure of the hat upon the temporal arteries and veins or their
main branches arrests the free circulation of the blood in the scalp and causes
baldness. Such pressure occurs only in the cases of persons whose head has a
fullness or convexity where the aforesaid arteries or veins are intersected by the
rim of the hat, whilst with persons who in such part of the skull have a depres-
sion or concavity there is no injurious pressure of the hat and baldness does
not ensue.
In order that the invention may be the better understood, drawings are
appended in which:-
Fig. 1 is a perspective view of a hat embodying our invention.
Fig. 2 is a plan of the same.
Fig. 3 shows an alternative method of carrying the invention into effect.
Referring to the drawings it will be seen that the inside of the hat is provided
with pads a which may be of any suitable shape according to the contour of the
wearer's head, and may be constructed of cork, felt, leather or other suitable
material, or they may be of rubber and inflated. The pads are so shaped and
are of such dimensions as to leave spaces between their ends, such spaces being
arranged as indicated in Fig. 2, in which the dotted lines e indicate a section of
a head at the point where the hat would bear, d are the arteries or veins, from
which by means of the pads all pressure of the hat is removed permitting the
blood to circulate freely to the scalp. Referring to Fig. 3, it will be seen that
instead of the pads a we form recesses e in the brim of the hat, the position of such
recesses and the number thereof being dependent upon the shape of the wearer's
head, it being obvious that where the outline of the head is very irregular the
hat will not come into contact with the head to the same extent as in the case
of a person whose head is approximately regular in contour. It is obvious that
instead of attaching the pads directly to the hat they may be formed upon a
separate band which may be secured to the hat in any convenient manner.

Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is
1. In a hat the provision of a means whereby the pressure thereof is removed
from the arteries or veins leading to the scalp thereby tending to preserve the
hair, substantially as herein set forth and shown by the appended drawings.
2. The improved hat having spaces or recesses at points where the blood carry-
ing vessels to the head occur, substantially as herein set forth and shown by
the appended drawings.
3. The improvements in hats for the purpose hereinbefore specified effected
by means of pads such as herein described or by recesses or spaces formed in the
hat itself substantially as described and illustrated by the appended drawings.
