PROVISIONAL SPECIFICATION.
An Improved Ventilator for Hats, Caps, and other Coverings for
the Head.
We JOHN PRESTON JOHNSON of 15 Gandy Street Kendal in the County of
Westmoreland, Sheep Merchant, and JOHN FLETCHER SHAW of 2 Elvey Street
Newton Heath in the County of Lancaster Draughtsman do hereby declare the nature
of this invention to be as follows:-
"Hat
This invention relates to an improved ventilator which can be adapted to any
kind of hat or head covering which we propose to call "The Capable
Ventilator.
The invention consists of a short tube fixed in the centre of the crown of the hat
the upper
end of which tube is conical in shape, and over this conical end is placed
a small concave circular plate or disc. This plate is slightly larger than the tube in
diameter, and is supported by small strips or pieces of metal fixed thereto. This plate
prevents rain, dust, or down draught from entering the hat, and in combination with
the conical tube produces a current of air across the mouth of the cone which, with
the assistance of eylet holes in the sides of the hat takes the heated air out at the top,
thus maintaining an agreeable temperature.
At the lower end of the tube inside the hat is an air regulator consisting of a fixed
plate and a loose plate. The fixed plate is attached to the lower end of the tube and
is provided with holes for the passage of the air, and the loose plate also has-holes and
blank spaces corresponding with those in the fixed plate.
The loose plate is kept against the fixed plate by a rivet passing through their
centres and the former is provided with a button or projection by means of which it
can be turned round so as to open or close the ventilating apertures more or less.
We would here remark that the form of the air regulator may be varied for
example, it may be made so as to slide instead of turning upon a pivot if
preferred.
The ventilator is fastened into the crown of the hat or other head covering by
means of a flange at or near the top of the conical tube outside and a nut screwed
onto the tube inside the crown.

We JOHN PRESTON JOHNSON of 15 Gandy Street Kendal in the County of
Westmoreland Sheep Merchant and JOHN FLETCHER SHAW of 2 Elvey Street
Newton Heath in the County of Lancaster, Draughtsman, 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 an improved ventilator which can be adapted to any kind
of hat, cap or other head covering.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings bereunto annexed and the following explanation thereof.
The drawing is made to an exaggerated or enlarged scale in order more plainly to
illustrate the construction of our improved ventilator.

page_text: Fig. 1 is a vertical section taken through the ventilator and Fig. 2 is an underneath
view of the same.
Figs. 3 and 4 are similar views of a modification thereof hereinafter described.
a represents part of the crown of a felt hat or other head covering.
The invention consists mainly of a short tube fixed in the centre of the crown of
the hat, the upper end 6 of which tube is slightly conical in shape, and over this
conical end is placed a small concave circular plate or disc c. This plate is slightly
larger than the tube a in diameter and is supported by small strips or pieces of metal d
fixed thereto. This plate prevents rain dust or down-draught from entering the hat,
and in combination with the conical tube produces a current of air across the
mouth of the cone which, with the assistance of eyelet or other holes in the sides
of the hat, takes the heated air out at the top, thus maintaining an agreeable
temperature.
At the lower end of the tube b (see Figs. 1 and 2) is an air regulator consisting of
a fixed plate e and a loose plate f.
The fixed plate e is attached to the lower end of the tube b and is provided with
holes for the passage of the air, and the loose plate falso has holes and blank spaces
corresponding with those in the fixed plate e.
The loose plate is kept against the fixed plate e by a rivet passing through their
centres and the former is provided with a button, ring or other projection g by means
of which it can be turned round so as to open or close the ventilating apertures more
or less as may be desired.
We would remark that the form of the air regulator may be varied for example,
it may be made (as shown at Figs. 3 and 4) so as to slide in and out of the tube b, or
it may slide or turn sideways if preferred.
The ventilator may be fastened into the crown a of the hat or other head covering
by means of a flange at or near the top of the conical tube outside, and a nut h
screwed onto the said tube inside the crown or the same may be provided with metal
tongues (Figs. 3 and 4) which are placed parallel with the tube when inserting the
ventilator through the top of the crown and when passed through- the opening are
expanded outwards as shown at Fig. 4 so as to retain the ventilator in its desired
position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
The construction and application to hats caps and other coverings for the head of
the improved ventilator consisting in the combination of a short slightly conical tube
provided outside with a covering plate, with an air regulator on the inside which is
capable of being opened or closed by turning or sliding the same substantially as
herein before described and illustrated by the drawing annexed.
