Improvements in Draught and Weather Excluders.
I, WILLIAM CHARLES TANNER, of 7, Moreland Street, Goswell Road,
London, E.C., Manufacturer, 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 :-
.
My invention relates to an improved self-acting draught and weather excluding
door slide of the kind wherein a bar of wood provided with an india-rubber strip is
pivotally attached to the lower part of a door so as to close the opening or space
between the lower edge of the door and the floor or step upon closing the said door,
and the chief object of the said invention is to effectually close the said space even
should the floor or step be hollowed out or worn away in the centre of the doorway
by continual treading thereon. For this purpose I fix to the centre of the rebated
piece of wood for receiving the moveable slide or bar, a small plate formed with a
single or double row or series of holes for receiving the screw attaching the upper
end of the pivoted arm to which the centre of the slide or bar is pivoted.
These holes are so arranged that by shifting the screw the leverage of the said
central arm may be increased the pivoted arms at each end of the bar remaining
always at the same leverage, thus causing the centre of the bar to be forced down
lower than the ends so that the said bar, and india-rubber strip, coincides with the
curved or hollowed out portion of the doorway or step when the door is closed thus
effectually closing the space below the said door.
I prefer to provide one end of the slide or bar with a stud which bears against a
plate fitted to the door jamb when the door is closed thus preventing the said end
of the bar being worn away by friction. The slide may be caused to operate on
doors hinged to either side of the doorway by simply altering the positions of the
pivoted arms and lifting spring in the usual manner.
In the accompanying sheet of drawings wherein like letters of reference indicate
corresponding parts,
Fig. 1. is a side view of my improved door slide or draught excluder looking
towards the side attached to the door and Fig. 2. is a cross section thereof, Figs. 3.
& 4. are similar views respectively to Figs. 1. & 2. but showing the positions of the
parts when the door is closed.
In the foregoing figures the slide is so arranged that it may be applied to a door
hinged to either side of the doorway, but in the arrangement shown in Fig. 5. the
slide can only be applied to a door hinged to one particular side, a is the rebated
piece of wood attached to the lower part of the door D for receiving the moveable
slide or bar b to which is attached the strip of india-rubber c, the bar being con-
nected to the piece a by the pivoted arms d d´and the spring k in the usual manner.
In the centre of the piece a is fixed a small plate provided with a single or double
row or series of holes f¹ for receiving the screw attaching the upper end of the
centre pivoted arm d' to the piece a, the lower end of the said arm being attached
to the centre of the slide or bar b. The upper end of the arın is attached to the
top hole of the series of holes ƒ when the floor or footstep 9 underneath the door is
perfectly level but when it becomes hollowed out by continual wear as shewn in
Fig. 3. the upper end of the arm d' is shifted and attached to one of the lower of
the series of the holes thus causing the central portion of the slide or barb to be
forced down lower than the ends thereof when the door is closed until it assumes
he curved form corresponding to the hollowed out floor g, thereby preventing any
pening or space being left between the bottom of the door and the floor h is a stud

fixed to the end of the slide or bar b which when the door is closed bears against
plate fixed to the inside face of the door jambj thus preventing friction and
wearing away at the end of the said bar b. To adapt the slide to a door hinged to
the opposite or left hand side of Fig. 3. the spring k is removed from its recess !
and fitted to the recess the pivoted arms being when in a contrary direction and
their lower ends attached to the screw holes 6' the upper end of the centre one d'
being attached to one of the opposite series of holes. In the arrangement shewn
in Fig. 5. it is only necessary to have one series or row of holes f¹.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is ;-
1. In a door slide or draught excluder the combination of the rebated piece a the
slide or bar b, strip c spring k, pivoted arms d d d' and plate provided with a
series or rows of adjusting holes f¹ substantially as described and for the purpose
specified.
2. In a door slide or draught excluder the employment. of a stud h fixed to the
end of the slide or bar b and a plate i fitted to the door jamb substantially as
described and for the purpose specified.
3. The improved door slide or draught excluder substantially as herein described
and shewn in the drawings annexed.
