PROVISIONAL SPECIFICATION.
Improvements in Diverting the Current of Air under Doors, so as
to Improve the Circulation of Air in a Room and Decrease the
Draught along the Floor.
1, THOMAS FORSYTH WILSON 1, Wellington Terrace South Shields Gentleman,
do hereby declare the nature of this invention to be as follows:-
My invention consists of a piece of wood of any required length, breadth and
thickness attached to the door of a room or building on the inside, by means of
hooks, pins or bolts and eyes and in such a position that it allows the air to come
in under the door and then rise up the door to the upper part of the room instead
of along the floor, thus freely circulating the air in the room and keeping the
lower part of the room free or nearly free from draughts and also an attachment
of a small spring of any suitable material so as to draw the bottom of the board
towards the door, thus allowing the door to open freely and pass over carpet.
Dated this Fourteenth day of January 1890.

COMPLETE SPECIFICATION.
Improvements in Diverting the Current of Air under Doors, so as
to Improve the Circulation of Air in a Room and Decrease the
Draught along the Floor.
I, THOMAS FORSYTH WILSON 1, Wellington Terrace South Shields Gentleman,
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 :-
My invention consists of a piece of wood of suitable length breadth and thickness
as may be required for any door, attached to the inside of the door of the room or
building, by means of suitable hooks, bolts or pins, so as to enable the board to swing
easily when the door is opened or shut.
To the bottom of this wood I fasten a piece of felt, india rubber, cloth, or any other
suitable soft material, to enable the wood to fit close to & pass noiselessly over the
floor. The wood is hung on the hooks at any required distance from the door, so as to
allow the air to come under the door, it then comes in contact with the wood passes
up the door, and circulates in the upper part of the room, instead of going along the
floor and chilling the feet or as some, do prevent its admission into the room, the air
of which soon becomes foul. Onto the end of the longitudinal piece as above next to
the opening of the door, is attached in a suitable manner an adjustable or fixed stop,
which, when the door is shut comes in contact with the door post, and in any suitable
position a spring of india rubber, steel or brass is attached to the longitudinal wood
and to the door, this spring draws the longitudinal wood towards the door when it is
opened, thus taking it off the floor, and allowing the wood to pass clearly over the
carpet.
When the door is shut the above described stop coming in contact with the post,
puts the longitudinal wood into vertical position resting on the floor.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
(1) The application of a longitudinal piece of wood to door to divert the air.
(2) The attachment of the stop in conjunction or separately with a spring.
(3) The general arrangement of the whole as above described.
Dated the 10th day of October 1890.
