PROVISIONAL SPECIFICATION.
Improvements in Draught Excluders.
We, JONES HENRY DAVIS, of The Grove, Tuam, in the County of Galway,
Physician and Surgeon, and RICHARD JOHN KINKEAD, M.D. of Forster House,
Galway in the County of the Town of Galway, Physician and Surgeon, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a device for preventing the entrance of draughts
under doorways and is so arranged that it does not bear upon the floor except
when the door is closed, at all other times being raised therefrom.
According to this invention as applied to the inside of doors opening into
a room or to the outside of doors opening outwards, we secure to the lower
edge of the door one edge of a strip of baize or other fabric of the exact
width of the door. Along the other edge of this strip we make a deep hem
to receive a rod, bar, or tube supported at one end by a pivot projecting from
the architrave of the door at a short distance from the floor. The other end
of this rod or tube enters sufficiently to support a short tube in which it is
free to slide as the door is opened and closed. This tube or bar is inserted
and secured in the end of the hem of the baize. A hook is secured to the
said rod or tube at a suitable point and projects through a suitable opening in
the baize. It is attached to a short chain secured at its other end to an eye
or pin driven into the door at a position above the said rod. It will be seen
that by reason of the rod being pivoted at a point beyond that at which the
door is hinged the movement of the latter will cause (I) the outer end of the
rod to move along the door, when the same is turned on its hinges: but inasmuch
as the rod is connected by means of a length of chain to the door itself this
movement will be prevented except in combination with a vertical movement, the
latter only being imparted to the short outer tube. (11) A separation of the rod
from the door greatest at the pivoted end and a consequent shallowing of the sling
formed by the baize. The effect of this will be to raise the said sling and the
weight suspended in it, at both ends. The width of this baize is sufficient to allow
it to hang in a fold or sling which will rest upon the floor when the door is shut.
This fold is kept in contact with the floor by means of a roller, sand bag, or other
suitable weight suspended within it.
As applied to the inside of doors opening outwards and the outside of doors
opening inwards we modify the herein before described arrangement in the following
manner :-
To the upper free end of the strip of baize or other material we secure a rod or
lath to the ends of which are attached cords running over pulleys mounted upon
the floor itself and connected at the other end to an eye secured to the architrave
of the door. It will be seen that the opening of the door will draw the said cord
over the pulleys and so raise the fold of the baize from off the ground. The other
edge of the baize is secured to the door and the fold is weighted as in the first
mentioned arrangement.

page_text: We, JONES HENRY DAVIS, of The Grove, Tuam, in the County of Galway,
Physician and Surgeon, and RICHARD JOHN KINKEAD M.D. of Forster House,
Galway in the Town and County of Galway, Physician and Surgeon, 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 a device for preventing the entrance of draughts under
doors, and is so arranged that it does not bear upon the floor except when the door
is closed, at all other times being raised therefrom.
According to this invention as applied to the inside of doors opening inwards or
to the outside of doors opening outwards, we secure to the lower edge of the door
one edge of a strip of baize or other fabric of the exact width of the door. Along
the other edge of this strip we make a deep hem to receive a rod, bar, or tube
supported at one end by a pivot projecting from the architrave of the door at a
short distance from the floor. The other end of this rod or tube enters sufficiently
to support an outer tube in which it is free to slide as the door is opened and
closed. This tube is inserted and secured at the end in the hem of the baize, and
extends to the edge of the door. It has a slot cut in the upper face and it overlaps
the rod a short distance as hereinbefore described. A hook is secured to the end
of said rod and projects through the slot in the tube above mentioned and through
a corresponding opening in the baize. It is attached to a short chain secured at its
other end to an eye or pin driven into the door at a position above the said rod.
It will be seen that by reason of the rod being pivoted at a point beyond that at
.which the door is hinged the movement of the latter will cause (1) the outer end of
the rod to move along the door, when the same is turned on its hinges: but
inasmuch as the rod is connected by means of a length of chain to the door itself
this movement will be prevented except in combination with a vertical movement,
the latter only being imparted to the baize and the short outer tube contained
therein. (2) A separation of the rod from the door greatest at the pivoted end
and a consequent shallowing of the sling formed by the baize. The effect of this
will be to raise the said sling and the weight suspended in it, at both ends. The
width of this baize is sufficient to allow it to hang in a fold or sling which will
rest upon the floor when the door is shut. This fold is kept in contact with the
floor by means of a roller, sand bag, or other suitable weight suspended within it.
As applied to the inside of doors opening outwards and the outside of doors
opening inwards we modify the hereinbefore described arrangement in the following
manner :-
To the free end of the strip of baize or other material we secure a rod or lath to
which are attached cords running over pulleys mounted upon the door itself or
contained in a case attached to the door and connected at the other ends to an eye
secured to the architrave of the door. It will be seen that the opening of the door
will draw the said cords over the pulleys and so raise the fold of the baize from off
the ground. The other edge of the baize is secured to the door above the pulleys
or to the pulley case above mentioned and the fold is weighted as in the first
mentioned arrangement. This latter arrangement can also be applied to a drop
weather board or to an ordinary hinged weather board.
And in order that our invention may be more fully understood and carried into
practice we will now proceed to describe the same with reference to the accom-
panying drawings, of which Fig. 1 is a view of our improved draught excluder as
applied to the inside of doors opening into a room, or the outside of doors opening
outwards and Fig. 2 section on line, x-y, Fig. 3 a view showing the excluder as

page_text: attached to the inside of doors opening outwards and the outside of doors opening
inwards, and Fig. 4 section on line x-y, and Figs. 5 and 7 views of modifications
thereof, and Figs. 6 and 8 sections thereof on lines x-y.
When applying my improved draught excluder to the inside of doors opening
into a room, as shown in Figs. 1 and 2 one edge of a strip of baize or other fabric a
is secured to the lower edge of the door and along the opposite edge of said strip a
deep hem is made to receive a rod, bar, or tube 6 supported at one end by a pivot c
projecting from the architrave of the door. The baize is so formed into a sling in
which is placed a rod of metal, sand bag, or the like as a weight.
The opposite end of said rod or tube b projects into a short tube d secured in the
hem of the baize, sufficiently to support it and in which it slides freely as the door
is opened or closed.
The rod or tube has secured to it by a ring or other means, which projects
through a slot d' in tube d and a similar opening in the baize, one end of a chain
the opposite end of which is secured to the door by a nail or the like at a position
above said rod so that the travel of the latter along the door as it is opened
will be prevented except in combination with a vertical movement the effect of
which will be to raise the baize and weight carried thereby out of contact with
the floor.
As applied to the inside of doors opening outwards (Figs. 3 and 4) one edge of
the baize a is secured to the door as above described whilst a rod or lathe is
secured to the other free edge. The ends of the rod or lath are attached to cords f
running over pulleys 9 mounted on the door and connected at their other ends to
an eye secured to the architrave of the door, so that as the door is opened said
cords will be drawn over the pulleys and so raise the fold of the baize off the
ground.
In Figs. 5 and 6 modification of this latter device is shown the baize being
replaced by a weather board j hinged to the door whilst in Figs. 7 and 8 an
ordinary drop weather board k replaces the baize two cords f and roller g being
used in this case.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A draught excluder and modifications thereof substantially as hereinbefore
described and illustrated in the accompanying drawings.
