I, GUSTAVE RIEUNIER of Gobowen Salop Professor of Modern Languages do
hereby declare the nature of this invention to be as follows:-
:-
My invention consists of a board of any convenient dimensions and thickness here-
after termed the draught box which is fixed to the bottom of the door and is kept in
position by suitable guards and stops which prevent the board sliding from right to
left or vice versa. A cam lever is fitted to the board by the action of which it is
raised or dropped. One end of such can lever is in contact with the end of a
propeller which is fitted to the frame of the door in any convenient position. Such
propeller is actuated by the opening and closing of the door in the same way as an.
ordinary door spring. When the door is opened this propeller has a forward motion
imparted thereto and so forces down the end of the cain lever with which it is in
contact while when the door is closed the backward travel of the propeller allows
the lever to drop. A cushion or piping is fixed underneath the draught board
which when in its normal position effectually excludes all draught dust and
damp.

page_text: I GUSTAVE RIEUNIER of Gobowen Salop Professor of Modern Languages 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 has for its object to provide a simple cheap and highly effective
draught dust and damp excluder which may be readily fitted to any door.
My invention consists of a board of any convenient dimensions and thickness here-
after termed the "draught board" which is fitted to the bottom of the door (preferably
on the inside thereof) and which is kept in position by suitable guards and stops which
latter prevent it sliding from right to left or vice versa. A curved rocking lever is
pivotted centrally or nearly centrally on the door by a screw pivot or other suitable
equivalent in such a manner as to allow such lever to move freely up and down as the
door opens and closes. The lower arm of the rocking lever is attached to the centre
of the draught board by means of one or more wires or their equivalents while the
upper arm of such lever is operated and depressed by a propeller that is fixed to the
frame of the door. This propeller works to and fro horizontally in a guide bracket
in a similar way to an ordinary door spring and it is so fixed that its free end is in
contact with the upper arm of the rocking lever so that as the door opens the propeller
by its forward travel depresses such upper arm thus raising the draught board and
allowing the door to open easily while as the door again closes such upper arm is
released from the pressure of the propeller and the lower arm is drawn downwards
by the weight of the draught board which then again descends to its normal position
at the bottom of the door. In order to effectually exclude the draught dust and damp
it is necessary that the draught board be fitted to the exact shape of the floor or other
surface immediately beneath it. I also fit the bottom edge of the draught board with
a suitable cushion lining or piping so that such bottom edge makes close contact with
the floor or other surface beneath it and thus perfectly excludes the draught dirt and
damp. It is obvious that the draught board is lifted in proportion to the width of
the propeller so that the wider the propeller the higher the draught board is raised.
When however the door is extremely wide say for instance 4 feet or more in order to
avoid having a very long propeller the draught board may be fixed at or near the
back edge of the door by means of a screw on which it works loosely while the
lower end of the draught board is rounded off to allow of such board working easily.
When the draught board is so fitted the rocking lever is likewise pivotted on the door
near its back edge instead of being placed centrally or nearly centrally thereon so
that in proportion as the space between the back edge of the door and the pivot of
the rocking lever is lessened so the length of the propeller can be diminished
and still allow the upper arm of such lever to be in contact with the free end
of the propeller in the manner and for the purpose already described.
If preferred the draught board may be fitted in the substance of the door which
may be recessed out in order to receive it. Or the thickness of the door may be
rebated at the bottom sufficiently to permit the draught board to be fitted thereon
flush with the surface of the door and it can then be covered over and concealed with
a face board only the propeller remaining visible.

parts.
Fig. 1 is a view in elevation of the lower portion of a door having my invention
fitted thereto and shewing the position of the draught board and other parts of the
apparatus when the door is shut. The dotted lines appearing in this figure indicate
the outlines of the face board with which the apparatus may be faced over if desired
as already mentioned.
Fig. 2 is a similar view shewing the position of the draught board and apparatus
when the door is open.

it works flower and upper arms of rocking lever-g connecting wire or wires

piping cushion or lining fixed at bottom edge of draught board.
Fig. 3 shews the apparatus fitted to a wide door in the manner hereinbefore
described the draught board being secured at one end by a screw round which
that end revolves while the other or free end only is lifted up-m is the rounded
corner of the board to permit of its working freely as hereinbefore described. When
fitted in this way on wide doors the apparatus works more effectively than if
fitted in the manner hereinbefore described and shewn at Figs. 1 and 2 of the
drawings.
The advantages of my invention may be briefly summarised as follows.
1. It allows of a thick carpet or even of a mat being placed before or behind the
door without interfering with the action of the apparatus.
2. It does not affect or injure the lock or hinges of the door.
3. It does not readily get out of order.
4. It is simple in construction and effective in action.
5. It may be readily fitted to any existing door.
6. It is not unsightly in appearance or awkward or clumsy in its action.
7. It never fails to work with the greatest efficiency.
8. It can be readily fixed and unfixed.
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. Fitting a door with an improved draught dust and damp excluding apparatus
consisting of draught board a-guides b-stops c-rocking lever d-fitted with
pivot e and furnished with lower and upper arms ff¹ connecting wire or wires g-
propeller -guide bracket i and lining piping or cushion k all constructed
arranged combined and fitted substantially in the manner and for the purposes
hereinbefore described and shewn at Figs. 1 and 2 of the accompanying drawings.
2. The modified construction arrangement and method of fitting such improved
draught dust and damp excluding apparatus all substantially as herein before described
and shewn at Fig. 3 of the accompanying drawings.
