Improvements in Draught Excluders for Doors.
We, WALTER THOMAS HALL and CHARLES JOHN AXTEN, both of 66, Hatton
Garden, in the County of Middlesex, Manufacturers and Merchants, do hereby
the nature of this invention to be as follows:-
:-
The invention relates to improvements in draught excluders for doors.
It is well known that many efficient devices are now in use for excluding
draughts passing the edges of closed doors at the top and sides thereof but
although a variety of schemes have been suggested for stopping the passage of
draughts beneath the bottom of the door where the current is greatest they
have been more or less inefficient or too expensive to come into general use.
Now the object of the present invention is to obtain a simple and inexpensive
device which will effectually block the passage of draughts beneath the door
and which at the same time will be easy of application and durable.
In carrying the invention into effect according to one arrangement a strip-
of wood of half round or curved section is employed and the curved side of
this wood strip is covered with a suitable thickness of cork carpet felt or other
suitable material but preferably a material that possesses a natural elasticity
spring or resilience and this covering of cork carpet or other material is firmly
attached to the wood strip by the aid of cement or other suitable fastening means.
This covered wood strip may be made in long lengths and afterwards cut up
by the aid of a saw into approximately suitable lengths for use and the pur-
chaser of a length exceeding the required measurements can readily cut the
same to fit the particular door to which it is to be applied.
In order to apply the device to a door it is cut to a suitable length and placed
on the outside of the door with its flat side downward upon the floor and fixed
by means of screws or otherwise in such a position that the door will close
against and wedge itself upon it, the springy or resilient nature of the covering
material assisting to that end and thus effectually close the crevice against
draughts.
It will be obvious that the details of construction of the device may be more
or less varied without departing from the spirit of the invention for example
instead of employing wood for the half round strip any other suitable material
may be substituted therefor and instead of forming the strip solid it may be
grooved or hollowed on its under side and when employing that construction the
strip may be formed of very thin steel or the like and the edges curled over the
edges of the covering material and by this hollow formation the strip itself
will possess a natural spring thus materially assisting to pack the door whilst
as a further modification the strip may be formed entirely of a suitable material
preferably elastic and such for example as india rubber or cork composition.
Although a half round or curved section is perhaps the most suitable for the
purpose in view it will be understood that any other suitable section such as a
half diamond may be substituted therefor.

We, WALTER THOMAS HALL and CHARLES JOHN AXTEN,, both of 66, Hatton
Garden, in the County of Middlesex, Manufacturers and Merchants, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-
The invention relates to improvements in draught excluders for doors.
It is well known that many efficient devices are now in use for preventing
draughts passing the edges of closed doors at the top and sides thereof but
although a variety of schemes have been suggested for stopping the passage of
draughts beneath the bottom of the door where the current is greatest they
have been more or less inefficient or too expensive to come into general use.
Now the object of the present invention is to obtain a simple and inexpensive
device which will effectually block the passage of draughts beneath the door
and which at the same time will be easy of application and durable...
In carrying the invention into effect according to one arrangement a strip
of wood of half round or curved section is employed and the curved side of
this wood strip is covered with a suitable thickness of cork carpet felt or other
suitable material but preferably a material that possesses a natural elasticity
spring or resilience and this covering of cork carpet or other material is firmly
attached to the wood strip by the aid of cement or other suitable fastening means.
This covered wood strip may be made in long lengths and afterwards cut up
by the aid of a saw into approximately suitable lengths for use and the pur-
chaser of a length exceeding the required measurements can readily cut the
same to fit the particular door, to which it is to be applied.
In order to apply the device to a door it is cut to a suitable length and placed
on the outside of the door with its flat side downward upon the floor and fixed
by means of screws or otherwise in such a position that the door will close
against and wedge itself upon it, the springy or resilient nature of the covering
material assisting to that end and thus effectually close the crevice against
draughts.
It will be obvious that the details of construction of the device may be more
or less varied without departing from the spirit of the invention, for example,
instead of employing wood for the half round strip any other suitable material
may be substituted therefor and instead of forming the strip solid it may be
grooved or hollowed on its under side and when employing that construction the
strip may be formed of very thin steel or the like and the edges curled over the
edges of the covering material and by this hollow formation, the strip itself
will possess a natural spring thus materially assisting to pack the door whilst
as a further modification the strip may be formed entirely of a suitable material
preferably elastic and such for example as india rubber or cork composition.

page_text: Although a half round or curved section is perhaps the most suitable for the
purpose in view it will be understood that any other suitable section such as a
half diamond may be substituted therefor.
And in order that the said invention may be more clearly understood and
readily carried into effect we will proceed aided by the accompanying drawings
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure is an outside elevation of a door illustrating the employment 'in
connection there with of a draught excluder constructed according to the present
invention.
Figure 2 is an edge view thereof with one of the door posts removed.
Figure 3 is an end view of the draught excluder separately.
Figure 4 is a plan or top view of part thereof and
Figures 5 to 10 are similar views to Figure 3 representing modified forms
of the device.
Referring to Figures 1 to 4 a represents the door of a room, b represents the
floor thereof and c represents the draught excluder.
cl represents a strip or base of wood or it might be other suitable material of
half round or curved section and the curved side of this wood strip is covered
with a suitable thickness of cork carpet c or the covering might be felt or other
suitable material but preferably a material that possesses a natural elasticity
spring or resilience and this covering of cork carpet or other material is firmly
attached to the wood strip by the aid of strong glue, shellac or other cement
or it might be by other suitable fastening means such as nails or screws.
The covered wood strip c c may be made in long lengths and afterwards cut
up by the aid of a saw into approximately suitable lengths for use and the
purchaser of a length exceeding the required measurements can readily cut the
same to fit the particular door to which it is to be applied.
In order to apply the device to a door such as the excluder c d is cut to a
suitable length to fit between the door posts a that is to sav. not quite co-
extensive with the width of the door a and placed on the outside thereof, with
its flat side downward upon the floor b; it is then pressed against the door
and thus fixed by means of nails or screws d or it might be by other suitable
means.
When the excluder is correctly fixed in position the door will close
against and to some extent wedge itself upon it, the springy or resilient nature
of the covering material c assisting to that end and the crevice beneath the
door will thus be effectually closed against draught.
In the example given at Figure 5 the device is constructed of a modified
section taking the form of half of a diamond but it will be understood that the
sectional shape of the device may be further varied if desired although the half
round section shown and described with respect to the previous figures is perhaps
the most suitable for the purpose in view.
In the example given at Figure 6 the wood strip or base c¹ instead of being
of solid construction as in the previous figures is in this case formed with a groove
or hollow in its underside by which means an additional spring or elasticity:
is given to the device and which will materially assist to pack the door and
when employing this construction the strip or base c¹ may with advantage be
built up of a number of thicknesses of cardboard or paper cemented together
and if desired baked in order to obtain the requisite stability.
In the example given at Figure 7 the device is substantially the same as
that lastly herein before described but in this case instead of the wood strip or
base c being formed with a single groove or hollow in its flat or underside it
is provided with several grooves or hollows or there might be only two in its
half round or upper side which has the effect of rendering the covering
material c more springy at those points.

page_text: In the example given at Figure 8 an excluder is shown of a similar hollow
section to that herein before shown and described with respect to Figure 6 but
in this case the strip or base c¹ is formed of very thin steel or the like and the
edges thereof are curled over or round the edges of the covering material c
and pinched into the latter so as to assist in holding it in place whilst in order
to enable the device to be fixed to the floor the covering material c and the metal
strip or base care at intervals furnished with coincident perforations for the
passage of nails or screws.
This form of the device possesses very considerable spring or elasticity and
strength or durability but inasmuch as it cannot be so easily cut into the
required lengths as the previous examples it cannot be regarded as so convenient
a form for general use.
In the example given at Figure 9 the wood or metal strip c¹ is dispensed with
and the device is assumed to be formed entirely of a body of suitable material
preferably elastic and such for example as compound india-rubber or cork
composition.
In the example given at Figure 10 a modification of this latter form of the
device is shown in which several holes are formed longitudinally through the
body of the material e and serve to increase the elasticity of the device and to
cheapen the cost of production thereof.
It will be obvious that the details of construction of the device may be other-
wise more or less varied without departing from the spirit of the invention.
By the means herein before described a simple efficient and inexpensive
draught excluder is obtained adapted to be readily fixed in position by any un-
skilled person and which by reason of its curved or equivalent upper surface
will not offer an impediment to persons passing over the same.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. A draught excluder for doors formed of half round, half, diamond or other
suitable section either solid or hollow and composed wholly or partly of cork
composition compound indiarubber or other suitable compressible or elastic
packing material and adapted to be fixed to the floor upon the outside of a door
manner substantially as herein shown and described and for the purpose
in
stated.
2. A draught excluder för doors formed of half round, half diamond or othe™
suitable section and composed of a base or backing of wood or other suitable
material covered with cork composition or carpet, felt, compound india-rubber
or other suitable compressible or elastic packing material and adapted to be
fixed to the floor on the outside of a door in manner substantially as herein
shown and described and for the purpose stated.
3. A draught excluder for doors formed of half-round, half diamond or other
suitable section hollow or grooved on the upper or under side and composed of
a base or backing of wood, metal, or other suitable material covered with cork
composition or carpet, felt, compound india rubber or other suitable com-
pressible or elastic packing material and adapted to be fixed to the floor upon the
outside of a door in manner substantially as herein shown and described and for
the purpose stated.
