An Improved Draught Excluder for Doors.
I, ROBERT THOMAS BURTON, of 14 South Vale, Upper Norwood, in the County
of Surrey, Builder, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide by simple cheap and efficient means
for exclusion or reduction of draught under doors whilst at the same time
enabling doors to be opened over carpets or floor coverings without its being
necessary for this purpose to employ hinges such as are known as rising butts.
According to my invention the door itself is made of such a height and is so
hung that the bottom of the door will pass over the carpet or floor covering of
the room or place into which the door opens and to the door there is applied
a rotary draught excluder in the form of a roller suitably covered it may be with
carpet or other material of the same kind as or more or less resembling the floor
covering, this roller being so applied that when the door is moved on its hinges
the roller will roll on the floor and that at all times it will have a tendency to
assume a position in which its periphery will be in contact with both the door
and the floor for which purpose it is mounted in brackets having inclined slots
or ways in them to receive the pivots or axle ends of the roller the said slots or
ways being inclined in a downward direction towards the door.
When my
draught excluder is applied to the inner side of a door then at the respective
sides of the doorway the stop of the door frame is suitably removed to make room
for the brackets that carry the roller.
Rollers and brackets may be variously constructed to operate as described when
applied to either side of a door.
01, ROBERT THOMAS BURTON, of 14 South Vale, Upper Norwood, in the County
of Surrey, 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 and by the following statement:-
MIL
invention is to provide by simple chean and efficient means

page_text: for exclusion or reduction of draught under doors whilst at the same time
enabling doors to be opened over carpets or floor coverings without its being
necessary for this purpose to employ hinges such as are known as rising butts.
According to my invention the door itself is made of such a height and is so
hung that the bottom of the door will pass over the carpet or floor covering of
the room or place into which the door opens and to the door there is applied
a rotary draught excluder in the form of a roller suitably covered it may be with
carpet or other material of the same kind as or more or less resembling the floor
covering, this roller being so applied that when the door is moved on its hinges
the roller will roll on the floor and that at all times it will have a tendency to
assume a position in which its periphery will be in contact with both the door
and the floor for which purpose it is mounted in brackets having inclined slots
or ways in them to receive the pivots or axle ends of the roller the said slots or
ways being inclined in a downward direction towards the door.
Rollers and brackets may be variously constructed to operate as described when
applied to either side of a door.
Fig. 1 of the accompanying illustrative drawings shows the lower part of a
door and its frame with a draught excluder according to this invention applied
to the lower outer side of the door. Figure 2 is a cross section on the line xx
of Figure 1. Figures 3 and 4 are elevations at right angles to each other showing
one of the brackets used for carrying the roller.
1 is a roller covered with carpet or other material 2 as hereinbefore explained
and having fixed to its two ends metal discs 3, 3 provided with pins 4, 4 that
are mounted to slide in inclined slots 5 formed in brackets 6, 6* which are secured,
as by screws, to the outer side of the door near to its two vertical edges and so
as to be flush with the bottom edge thereof as shown. The stop or fillet 7 of
the door frame 8 at the hinged side of the door is recessed so as to receive the
brackets 6 and allow the same to fit snugly up against the door frame, when the
door is closed. The bracket 6* fixed to the opposite edge portion of the door
may be similarly recessed into the opposite stop or fillet 7 of the door frame
which is suitably recessed or cut away to enable this bracket to clear it when
the door is opened. Or the said bracket may be placed near to the said edge
of the door, and adjacent to the stop 7 with sufficient clearance to allow of the
door opening without fouling the door frame.
As will be seen, with the arrangement described the roller 1 can be so arranged
that when the door is closed it will hear simultaneously against the door and
against the floor 9 so as to effectually close the opening below the door and prevent
draught therethrough, and that when the door is opened the roller will roll on
the floor covering 10 of the room into which the door opens and if this be at a
slightly higher level than the floor 9 outside the door, the roller will be free to
be forced upward in its brackets by pressure against the carpet or other floor
covering 10 over which it is moved."
As will be obvious a rotary draught excluder of the kind described can be
applied to the inner side of a door, but I do not consider this so advantageous
an arrangement as that shown and described as it will necessitate more cutting
away of the door frame on the hinge side of the door to permit the door to be
opened fully back against the frame, to which it is hinged, and the roller will
not rise so readily in its bracket by a pushing movement as by a drawing move-
ment.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. The use in conjunction with a door so hung that its lower edge will pass
freely over the carpet or other floor covering of the room or place into which the
door opens of a rotary draught excluder comprising a roller so mounted that when
the door is moved on its hinges the roller will roll on the floor and that at all

page_text: times it will have a tendency to assume a position in which its periphery will
be in contact with both the door and the floor, substantially as herein described.
2. A draught excluder for doors comprising a roller covered or not with carpet
or other material, and brackets adapted to be secured to a door as described and
formed with inclined slots or ways that incline in a downward direction towards
the door and serve to receive the pivots or axle ends of the roller, substantially
as hereinbefore described for the purpose specified.
3. My improved draught excluder for doors, constructed, arranged and operat-
ing as herein before described with reference to and shown in the drawings
annexed.
