PROVISIONAL SPECIFICATION.
An Improved Dust and Draught Protector for Doors and the like.
WILLIAM WRIGHT, Brassfinisher, 24, Tavistock Road, Plymouth, Devon, 'and
THOMAS HENRY LIDSTONE, Advertising Agent, The Octagon, Union Street,
Plymouth, do hereby declare the nature of this invention to be as follows:-
I take a piece of wood or other suitable material on the edge of which I
fix a rim made of rubber or other suitable material. On the top edge I fix
suitable hinges. I then fix the same on the door the bottom edge bearing
firmly on the ground or floor. As the door is opened by suitable means I cause
the protector to rise on its hinges so as to clear over carpet or other impedi-
ments which the door will pass over. On the upright of the door I fix a suit-
able stud or guide so as when the door is closed it guides the protector into its
proper place and prevents all draught and dust passing under the door.

An Improved Dust and Draught Protector for Doors and the like.
We, WILLIAM WRIGHT, Brass Finisher, of 24, Tavistock Road, Plymouth,
County of Devon, and THOMAS HENRY LIDSTONE, Advertising Agent, formerly
of The Octagon, Union Street, Plymouth, now of 24, Tavistock Road, Plymouth,
in the County of Devon, 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 relates to an improved dust and draught protector for doors
and the like, its object being the provision of means whereby the gap between
a door and its framing, or the floor, may be closed and draughts, etc. excluded.
Dust and draught protectors or excluders according to this invention are so
constructed that they do not come into contact with the floor or the fixed fram-
ing until the door is closed, and thus there is no friction between those parts
and the excluder when the door is in motion.
In carrying out this invention a flap or strip is hinged to the lower portion
of the door in such a position that if the flap is pressed close against the door
its bottom edge will come into contact with the floor and exclude draughts, etc.
Normally the flap is raised, preferably by a spring, so that as the door moves
there is no friction between the flap and the floor. When the door is closed
the flap is brought into contact with a portion of the framing, or other stationary

page_text: object, and is thereby pressed against the door, its lower edge coming into
contact with the floor. The lower edge of the flap is conveniently provided
with a strip of rubber or other compressible material to render the exclusion
of the draught more complete.
In the accompanying drawings,
Figure 1 is a perspective view showing one construction of draught excluder
according to this invention attached to the bottom of a door,
Figure 2 is an end elevation to a much larger scale showing the position of
the excluder when the door is open, and
Figure 3 is a similar view showing the position of the excluder when the door
is closed.
Like letters indicate like parts throughout the drawings.
A is a door having a flap B attached to its bottom portion by means of
hinges B. A piece of rubber tubing 12 is fastened upon the lower edge of the
flap B.
A spring C is placed between the flap B and the door so that normally
the flap is raised, as shown in Figure 2, and its bottom edge held out of contact
with the floor. A recess D¹ is formed in the jamb D of the door to accommo-
date the excluder when the door is closed. Figure 3 shows the position of the
excluder when the door is closed, the flap B being pressed close against the
door against the action of the spring C, and the gap at the bottom of the door
being closed so as to exclude draughts, etc.
It is to be understood that excluders according to this invention may, if
desired, be fitted upon any convenient portion of a door where it is necessary
to exclude draught, and are not necessarily fixed upon the bottom as in the
example illustrated. They may also be fitted between two doors. Further,
although it is convenient to use the jamb of the door as a means for pressing
the hinged flap against the door, yet other means, such as for example a pro-
jection attached to the framing or to the floor may be employed for that purpose.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
-
1. A draught excluder constructed and operating substantially as described
when the door is closed.
2. The combination with a door of a hinged flap which is pressed against
the door when the latter is closed substantially as and for the purpose described.
3. In a draught excluder for doors and the like the combination with a flap
such as B hinged to the door and extending into or against the jamb of a recess
in the jamb so arranged that while adapted to receive the end of the flap when
the door is closed it also serves to close the flap substantially as described.
4. The complete draught excluder substantially as described and illustrated
in the accompanying drawings.
