Leod at the Office of the Commissioners of. Patents, with his Petition,
on the 10th March 1862.
I, ALEXANDER CHARLES. MACLEOD, of Hanover Square, in the County of
Middlesex, Doctor. of Medicine, do, hereby declare the nature of the said...
Invention for "IMPROVEMENTS IN VENTILATING HATS AND COVERINGS FOR THE.
HEAD," to be as follows:-..
My improvements in ventilating hats and coverings for the head are applicable..
to any ordinary hat or other covering for the head. This ventilation is effected
by means of apertures in the body of the hat at a height corresponding or-
approximating to the top of the head of the wearer, the said apertures being
protected by a band or fillet, also perforated, or the perforations instead of
being in the fillet may be in the brim or in both.

Office on the 9th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
CHARLES MACLEOD, of Hanover Square, in the County of Middlesex, Doctor
of Medicine, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of March, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Alexander Charles MacLeod, Her special licence that I, the said Alexander
Charles MacLeod, my executors, administrators, and assigns, or such others
as I, the said Alexander Charles MacLeod, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands; and Isle of Man, an
Invention for "IMPROVEMENTS IN VENTILATING HATS AND COVERINGS FOR THE
HEAD," upon the condition (amongst others) that I, the said Alexander
Charles MacLeod, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention
and in what manner the same was to be performed, and cause the same
to be filed in the Great, Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent..
NOW KNOW YE, that I, the said Alexander Charles MacLeod, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
(No. I.) The nature of the said Invention of improvements in ventilating
hats and coverings for the head are applicable to any ordinary hat or covering
for the head. The ventilation is effected by means of apertures or tubes in
the body of the hat at a height corresponding or approximating to the top of
the head of the wearer, the said apertures or tubes being protected by a
projecting band or fillet, also provided with apertures, or instead of any
apertures in the fillet there may be apertures in the brim or in both fillet and
brim, the apertures in the body being always necessary.

page_text: (No: II:) Having thus particularly described the nature of the said Inven- *
tion, I now proceed to particularly describe and ascertain in what manner the "
same is to be performed; wherein I shall refer to the accompanying Drawings
by the words, figures, and letters marked thereon, and herein referred to, that
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a round-top hat complete; Fig. 2, two views of the hat
and fillet or band detached, as they would appear prior to being secured
together and made to form the complete ventilating hat, as shewn at Fig. 1
aforesaid; Fig. 3, a round-top hat, in which, instead of the air ways in the
crown or body of the hat being short tubes or apertures, as in Fig. 1, the
same are in this case elongated into oblique or bent tubes, as shewn; Fig. 4
shews the application of this Invention to. a soldier's helmet...
In the said Figures A denotes the fillet or band, and B the body or crown
of the hat; a denotes the upper air ways, apertures, or tubes, which are in
the body or crown of the hat; and 6, the lower air ways or apertures, which
are in the fillet or band, as aforesaid; c, the elongated air ways, tubes, or
apertures to be used, if desired, in the crown or body of the hat in lieu of the
above-described short tubes or apertures. The lower air ways, tubes, or
apertures, instead of being through the fillet, as shewn by the Drawings, may
be through the brim, so as to open into the passage between the body and
fillet, or both through the fillet and through the brim. When the elongated
air ways or tubes are adopted, should the fillet from any cause be detached
from the bat, ventilation will still be provided for as when the fillet was on, for
the great feature of this Invention, the provision of efficient air ways through
which the sun's rays or the wet cannot enter, is still carried out. In con-.
structing a hat, according to my Invention, it will be indispensably necessary
to leave an interval between the inner side of the fillet or band and the body
of the hat, and the more effectually to ensure this I place pieces of cork, felt,
or other material, interposing the same at given distances; or in lieu thereof
the body of the hat may be moulded into projections affording the same
support. And it will be obvious that this Invention can be applied to ordinary
hats already manufactured, it being only necessary to make the upper air
ways or apertures, and put on the fillet or band before mentioned.
(No. III.) Having now particularly described and ascertained the nature
of the said Invention, and in what manner the same is to be performed,
I declare that I claim the Invention the nature and character whereof is set

page_text: forth in the outset of this Specification (at the part beginning at No! I. and
ending at No. 2).
In witness whereof, I the said Alexander Charles MacLeod, have
hereunto set my hand and seal,' this Eighth day of September in the
year of our Lord One thousand eight hundred and sixty-two."
