PROVISIONAL SPECIFICATION.
Draught-preventing Apparatus.
"
I, NORMAN WILLIS RUSs, of "Rozel Holmesdale Road, Kew, in the
County of Surrey Electrician do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to provide a simple & effective means for the
purpose of preventing draughts passing under doors.
The means whereby I accomplish my object is to provide a roller which may
conveniently be of turned wood similar to an ordinary blind roller. This may be
covered with a soft material such as felt, cloth or carpet & is made the same length
as the width of the door to which it is to be fastened. The roller is then fastened
either on the inside or outside surface of the door as may be found most convenient,
but at the bottom of the same & in such a position that shall be in close contact
with the door itself & shall also touch the floor or carpet over which the door passes
when it is being opened or shut.
At each end of the roller I provide a bracket for the purpose of attaching it to
the door, with suitable means for it to slide up & down in order that it may be free
to ride over any unevenness of the floor or carpet, at the same time revolving upon
its axis by reason of its friction with the floor. The brackets may be made in such
a manner that they shall form bearings for an axle at each end of the roller with
vertical slots so that the axles may be free to move up & down therein or they
may be of such a form to carry the rollers themselves without axles but with
freedom to revolve as described.

COMPLETE SPECIFICATION.
Draught-preventing Apparatus.
I, NORMAN WILLIS RUSS, of " Rozel," Holmesdale Road, Kew, in the
County of Surrey, Electrician, 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 improved means for preventing draught under doors and
consists in the use of a roller in the novel manner hereinafter described.
In the accompanying drawing, —
Figure 1 is a front elevation of the lower portion of a door having my roller
draught-excluder applied thereto; and,
Figure 2 is a side elevation of the same:
Figure 3 is a view similar to Figure 2 illustrating a modification of my
invention.
a indicates the lower portion of the door, and b the floor. c is my roller which
is arranged along the bottom of the door so that it bears upon the floor. The said
roller which is conveniently made of wood and covered with a soft material such as
plushette, felt or cloth is placed against the bottom of the door either on the inside
or outside thereof and preferably also in contact with the door, the said roller
being held in the required position by means of the brackets d, d which extend-
over to the front of the roller, as shewn most clearly in Figure 2, but are opeu at
the bottom. Sufficient space is also provided in the brackets above the roller so
that the latter may rise when, in moving the door, it meets with any inequality or

page_text: unevenness such for instance as a carpet and ride over the same, the said roller at
the same time revolving on its own axis by reason of its contact with the floor.
In cases where my draught-excluder is used upon a door with a sill, as shewn in
Figure 3, the roller if arranged as herein before described would tumble out of the
brackets d, d when the door is opened, I therefore provide the ends of the rollers
with pivot-pins or axles e and I form in the brackets d, d slots fin which the said
pins or axles can move freely, the said slots and pins serving to prevent the roller
from falling out of the brackets when the door is moved away from the sill; or
instead of the said slots and axles or pins, the brackets themselves may be adapted
to support the ends of the rollers.
As it might sometimes be considered desirable to allow the air to enter beneath
the door but at the same time prevent it from blowing directly over the floor, I
adjust the roller at a slight distance from the door by introducing a piece of
packing material between the said roller and door, so that space is left between the
latter and the roller.
•
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A draught-preventer for a door consisting of a roller held against the bottom
of the door in such a manner that it will move with the door but will ride over any
unevenness of the floor, substantially as described.
2. The combination with a draught-excluding roller adapted to be held against
the bottom of a door of brackets so constructed that the said roller can move
vertically therein, substantially as, and for the purpose, described.
3. The manufacture and use of the improved draught-excluding apparatus herein-
before described and illustrated in the accompanying drawing.
