The cap A is screwed and perforated with holes.
The cap B is perforated with holes, and fits into the interior of cap A and is
fixed in that position.
The cap C is also perforated with holes corresponding both in number and
position to those in cap B:-and screws on to cap A.
The cap D screws on to cap C and is intended to protect the ventilator when
not in use.
The space E between the caps A and B is filled with wool, or asbestos. to
prevent the entrance of dust, and to filter the air passing through the ventilator.
By slightly turning the cap C the holes in B are opened or closed at will thus
admitting the air, or not, to the interior of the article to be ventilated.
In fixing: An opening is made in the boot, shoe, or hat, the cap A is inserted,
on one side, the wool and cap B is then placed in position and the cap C is
screwed on to A.
By opening the ventilator as before described fresh air is introduced into the
article to be ventilated, and the heated air allowed to escape.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to he performed, I declare that what
I claim is:
