Improvements in Draught Excluders.
RICHARD RAW, Grocer, EDMUND RAW, Spinner, and JOHN PAGE, Loom
Tuner, all of Charles Street, Morley, near Leeds, in the County of Yorkshire, 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:-
Our object is to make an improved draught excluder, to fix upon the inner side
of doors, which shall have a falling and rising motion, when the door is being
closed or opened, and for preventing any friction of the draught excluder upon
the floor of a room, and also preventing the ingress of cold air, dust, &c., when the
door is closed.
Figure 1. is a section of a door and the frame, A. being the inside face of
the door, B. the side of the frame to which the door is hung by its hinges, and
C. the side of the frame against which the door is shut.
In carrying out our invention, we make use of a flat bar of wood, or other
material D. the length of which we make of the width of any door it may have to
be fixed upon. The said bar D. is fixed to the door in order to prevent the ingress
of cold air, &c., under the door. In the said bar D. we bore a hole of a suitable
size as in Figure 2. at a¹. Upon the inside face of the door, we fix, in a suitable
manner, a brass or other metal casting a², the said casting being made with a pivot
upon its inner side as in Figure 3. at a³. At the reverse end of the door A. upon
its inner face, we fix a casting of brass or other metal, the said casting forming_a
guide or slide a', when fixed upon the door as in Figure 4. for the flat bar D.
Upon the upper edge of the flat bar D, we fix a casting of brass or other metal d',
the shape of the said casting being as in Figure 5. In the door frame B, we fix a
screw or pivot 61, as in Figure 6. this is for pressing against the upper portion of
the casting d', when the door is being closed. We fix one end of a spiral spring d³
in a suitable position to the door A. at a', and the other end of the said spring, we
fix to the flat bar D. at d². The said spring d³ is for the purpose of gradually
raising the flat bar D. up from the floor, when the door is being opened; and for
keeping it raised, until the door may have to be closed again.
The manner of operating our invention is as follows:-
The various parts are made and fixed upon the door and door frame and bar D.
as described in Figures 1. 2. 3. 4. 5. and 6, the flat bar D. having the casting a²
fixed upon it, by putting the pivot through the hole a', the casting a² being then
screwed to the door A. When the door is open, the flat bar D. is held in the
position indicated in dotted lines at d, by the spiral spring d³. As the door is
being gradually closed, the upper end of the casting d' is gradually made to press
against the screw or pivot , with a consequence that it causes the flat bar D,
working upon the pivot of the casting a² and sliding in the guide a', to be gradually
depressed, until, when the door is fully closed, the flat bar D. is close to the floor,
thus the ingress of cold air, dust, &c., is prevented. When the door is gradually
opened, the reverse operation ensues, and the spiral spring d³, (which when the
door was being closed was gradually stretched) gradually raises the flat bar D, as
the said bar is gradually released from the pressure of the screw or pivot b³, until,
when the door is fully open, the flat bar D, is at the position indicated by the
dotted lines d*.

page_text: 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:-
The employment of the screw or pivot b¹; the casting d'; the guide or slide a*,
the casting a²; and the spiral spring d³, in combination with the flat bar D. for the
purpose of forming a "draught excluder," and for the purpose of giving a falling
and rising motion to the said flat bar D. as described.
