AnjImproved Draught Excluder.
I WILLIAM FREEBURY, of 187, High Street, Harlesden, in the County of
Middlesex Builder do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct a simple cheap and effective device
suitable for attachment to the doors and windows of Buildings Rooms Railway
Carriages and the like for the purpose of preventing draughts rain snow and dust
from entering the Buildings or Vehicles to the doors or windows or both of
which my improved Draught Excluders are attached. Now according to this in-
vention as applied to doors I provide a moving strip or weather board of any
suitable material the bottom of which strip may be covered with or formed of
Indiarubber Vulcanised fibre or any other suitable material which is slightly
flexible and preferably waterproof. The moving strip which is of about the
is wide is
same length as the door to which it is to be applied
secured in a suitable casing of wood or other suitable material. The
casing which is of approximately the same length as the door is wide is
secured to the door by screws or otherwise at such a height above the floor
that the bottom of the casing will clear the carpet or mat when the door is opened.
The strip or weather board projects beyond the casing at one end and is secured
in the cusing by means of screws or pins passing from side to side of the casing
and through inclined slots in the said strip which is normally held within the
onsing by means of a spring or springs so that when the door is opened the strip
or weather board will be drawn within the casing so as to enable the bottom of
the weather board to clear the carpet. The casing is attached to the door in such
a manner that the projecting end of the weather hoard projects beyond the door
at the hinged end and when the door is closed the projecting end comes in. con-
tact with the door frame and forces it inwards when the cam action of the inclined
slots and pins depresses the weather board until it rests on the carpet or door sill
When the door is opened the spring or springs lifts or lift the weather board out
of contact with the sill or carpet. To render the apparatus more certain in action
I may form inclined planes in the casing and at the projecting end of the strip
so that when the door is closed the action of the planes on one another will de-
press the strip.

page_text: I, WILLIAM FREEBURY, of 187, High Street, Harlesden, in the County of
Middlesex, Builder, 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 und by the following statement:-
This invention relates to an improved draught excluder and has for its object
to provide a simple, cheap and effective device for attachment to the doors and
windows of buildings, railway carriages and the like for the purpose of excluding
draught, ruin, snow and dust.
According to the invention I provide the bottom of the door or window with a
suitable casing and in conjunction with the said casing I provide a movable strip or
weather board of suitablo material connected to the said casing by pins or studs,
working in inclined slots, and normally (that is to say, when the door is open)
held by a spring or springs in the casing in such a manner that one end thereof
projects laterally from the said casing, which is secured to the doar at such a
height above the floor that the movable strip clears the carpet or the like when
the door is open.
With this construction when the door or window is closed, the projecting end
of the weather board comes in contact with the door jamb or window frame so as
to force it downwards by the action of the inclined planes whereby its lower edge,
which is preferably provided with a length of rubber tubing, vulcanised fibre or
the like, comes into contact with the floor or window sill so as to effectually
exclude draught, rain and the like.
In practice I find it advantageous to form inclined planes upon the casing and
the weather board, the said inclined planes serving to assist the inclined slots in
causing the weather board to move obliquely in the casing.
To enable my invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure 1 is a view of a door having my improved draught excluder applied
thereto, the door being shewn opoLed:
Figure 2 is a view of the door shewing it closed:
Figure 3 is a back view of my draught excluder drawn to an enlarged scale;
and,
Figure 4 is an end elevation thereof.
A is the door and B the frame thereof; a is the casing, the said casing being
of practically the same width as the door and being secured thereto by any suit-
able means and 6 is my movable strip or weather board which fits into and is
arranged to slide in a rebate in the casing a, the said strip being of the same
length as the casing and being held therein by screws c, c fixed to the casing,
which screws pass through slots d, d in the movable strip or weather board b.
e is the spring (in the drawing only one spring is shewn although it will be
obvious that two or more such springs may be used if desired) by means of which
the strip 6 is held with its upper edge in contact with the upper edge of the
rebate in the casing as shown in full lines in Figure 3. In this inner position,
owing to the slots d being inclined as shewn, one end of the said strip b projects
beyond the casing on the hinge side of the door, as clearly shewa in Figure 1 aud
in full lines in Figure 3 and owing to the height at which the casing is secured
to the door the said strip clears the carpet or the like when the door is open as
above stated.
f is the compressible rubber tube fixed to the lower edge of the movable strip b

page_text: and 9, hare the inclined planes formed respectively upon the casing a and strip b
for the purpose of assisting the oblique movement of the strip b when the door
is closed.
With this construction it will be obvious as above described that when the door
is closed the portion of the strip b which projects beyond the casing a will come
into contact, before the door is quite closed, with the door jamb or frame on the
hinge side of the door so as to press it inwards. The inward pressure on the strip
will cause it to be moved obliquely downwards by the pins working in the in-
clined slots & and by the inclined planes y and h so that when the door is closed
the rubber tubo f is held in contact with the floor so as to form an effective
draught excluder. On opening the door the spring e draws the sliding strip b
up into the casing so that it can clear the carpet.
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
cluim is:-
1. A draught excluder for doors and windows consisting of a casing adapted
to fit along the bottom of the door or window and arranged to. receive a sliding
strip or weather board which is connected to it by pins working in inclined slots
and is, when the door is open, held by a spring or springs, clear of the floor or sill
and with one end projecting from the casing, the said projecting end, on the
door being closed, coming into contact with the frame thereof so as to cause the
sliding strip to be pressed downwards into contact with the floor, substantially
as described and illustrated.
2. The improved draught excluder, herein before described and illustrated in
the accompanying drawing.
