PROVISIONAL SPECIFICATION.
Improved Means of Ventilating Hats, Helmets, Caps, and other
Coverings for the Head.
I NATHANIEL JACOBSON of Clarence Hat Works Dutton Street Cheetham
Manchester, in the County of Lancaster Hat & Cap Manufacturer, do hereby
declare the nature of this invention to be as follows:-
-
The object of this invention is to apply an efficient ventilator to a hat helmet cap
or other head covering.
For this purpose at or about the centre of the crown of the cap or other head
covering I make a circular hole of about inch in diameter in the cloth or other
material of which the cap is made and in this hole I insert from the inside a dome
or button shaped ventilator provided with a flange or other suitable means of
fastening it in the hat. This ventilator is made of wire gauze or other suitable
open material or fabric.
The "tip" of the lining of the cap or other head covering is made of net or lace
cloth or other similar suitable open-work fabric and the inter-lining is cut away for
a considerable distance around the ventilator so as to leave a space between the
openwork lining and the cap for the hot air to circulate and escape through the
dome shaped ventilator.
For helmets and hats especially those for use in hot climates one or more of these
ventilators is or are by preference inserted at the front or back or sides of the
helmet or hat so that the air can enter for example at the brow and escape from the
crown.

COMPLETE. SPECIFICATION.
Improved Means of Ventilating Hats, Helmets, Caps, and other
Coverings for the Head.
I NATHANIEL JACOBSON of Clarence Hat Works Dutton Street Cheetham,
Manchester in the County of Lancaster Hat and 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:-
The object of this invention is to apply an efficient ventilation to a hat helmet cap
or other head covering.
My invention will be readily understood from the accompanying drawings and
the following description thereof.
Fig. 1 is an outside plan of part of a cloth cap with my invention applied thereto.
Fig. 2 is an elevation of the said cap partly in section and
Fig. 3 is an inside plan of part of the cap with the tip torn away to show the
ventilator more perfectly.
According to my invention at or about the centre of the crown of the cap or
other head covering I make a circular hole of about half an inch in diameter in the
cloth or other material a of which the cap is made and in this hole I insert from
the inside a done or button shaped ventilator b see also detached section Fig. 2ª
provided with a flange b¹ or other suitable means of fastening it in the cap a. This
ventilator is made of wire gauze or other suitable open material or fabric, and the
[Price 8d.]

page_text: dome or raised centre thereof allows the hot air to accumulate and escape in much
larger volumes than does the ordinary flat ventilator.
The "tip" of the lining of the cap or other head covering is made of net or
lace cloth or other similar suitable open-work fabric and the inter-lining d.is cut
away for a considerable distance around the ventilator 6 (see Figs. 2 and 3) so as
to leave a space between the open-work lining e and the cap a for the hot air to
circulate and escape through the dome shaped ventilator b.
For helmets and hats especially those for use in hot climates one or more of
these ventilators is or are by preference inserted at the front or back or sides of
the helmet or hat so that the air can enter (for example) at the brow and escape
from the crown, where I prefer to make the ventilator of larger diameter (say
about one inch and a quarter).
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved means for ventilating hats helmets caps and other coverings for
the head substantially as hereinbefore described and illustrated by the drawings
annexed.
2. The dome shaped wire gauze ventilator substantially as hereinbefore
described and illustrated by the annexed drawings.
