PROVISIONAL SPECIFICATION.
Improvements in Draught or Dust Excluders.
I THOMAS DAWSON of 116 Eastbourn Road, Birkdale, in the County of
Lancaster, Joiner and Carpenter, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved draught or dust excluder, adapted to be
attached to the edges of the jambs or lintels of doors, to window frames, drawer
frames or the like, or to the edges of the doors, windows, drawers, etcetera, them-
selves.
The invention has for its object the production of a simple and comparatively
cheap article of this description which can be readily cut to the required length and
attached to the desired part.
In carrying my invention into effect I employ as a backing a strip of wood or
other suitable material, either plain, moulded or ornamented, adapted to be attached
by nails, screws or otherwise to the desired part.
Along one edge of this strip I place a thick layer of soft yielding material, pre-
ferably an untwisted cord of wool, which may be let partly into a groove in the
edge of the strip.
The aforesaid soft material is held in position by a strip of cloth, baize or the
like, which is folded over it, and is attached at its edges to the back and front faces
of the backing. It is preferable to extend the baize over the whole of the rear
face of the backing so as to prevent the draught or dust finding its way between
the said backing and the part to which it is attached. The baize or its equivalent
may be secured to the strip by glue or otherwise.
In using the excluder the flexible part of it is placed upon or adjacent to the
chink which it is desired to close and the rigid backing secured to the part adjacent
by nails, screws or otherwise.

COMPLETE SPECIFICATION.
Improvements in Draught or Dust Excluders.
I, THOMAS DAWSON of 116 Eastbourne Road, Birkdale, in the County of
Lancaster, Joiner and Carpenter, 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 draught or dust excluder adapted to be
attached to the sides or edges of the jambs or lintels of doors, to window
frames, to drawer frames or the like, or to the doors, window sashes or drawers
themselves.
The invention has for its object the production of a simple and comparatively
cheap article of this description which can be readily cut to the required length; and
attached to the desired part.
It is best described by the aid of the accompanying drawings, in which,
Figure 1 shows, in front elevation, the bottom of a door with my device attached
thereto.
Figure 2 is an elevation of the back of the device.

door, and door jamb.
Figure 5 is a front elevation of a portion of the device together with a part of
the door, and door jamb, and
Figure 6 a cross section through the middle hinge and spring.
Figure 7 is a front elevation of sliding window sashes with my device attached
thereto.

Figure 10 a cross section on the line z z, Figure 7 and
Figure 11 an elevation and cross section of the draught excluder on an enlarged
scale adapted more especially for window sashes.
Referring to these drawings,
A is a backing or strip of wood or other suitable material either plain, moulded
or ornamented, and adapted to be attached by nails, screws or otherwise (see
Figures 7 to 11 inclusive) or by hinges (see Figures 1 to 6 inclusive) to the desired
part. Along one edge of this strip A. I place a cushion consisting of a thick
layer of soft yielding material B, preferably an untwisted cord of wool, which may
be let partly into a groove in the edge of the strip A or otherwise.
The aforesaid soft material B is held in position by a strip of cloth b, baize, or
the like, folded over it, and attached to the front or back faces of the backing A.
It is preferable to extend the baize b along the whole length of the strip A so as
to prevent the draught or dust finding its way between the said strip A and the
part to which it is attached. The baize or its equivalent may be secured to the
strip A by glue or otherwise.
In Figures 1 to 6, inclusive, the strip A is attached to the bottom of the door by
means of hinges a a¹. The middle hinge a¹ is provided with a spring a² (Figure 6)
which is adapted to raise the strip A with the yielding material B from the
ground. C is a hood fixed to the door by means of screws and preferably running
the whole length of the strip A, and adapted to cover the top of the said strip.
Dis a stop secured to the door jamb.
The mode of action of this part of the invention is as follows:-
When the door is open, the strip A is raised from the ground by means of the
spring a² (see Figure 6) which permits of the doors being freely opened or closed.
When, however, the door is shut, the strip A presses against the stop D which
closes the strip against the door and causes it to lie flat therewith or approximately
so, whereby the flexible part closes the chink under the door and excludes the
draught. As shown in Figure 2, the yielding material B may be loosely fitted at
and near its middle to the strips, whereby it can be adjusted (see dotted line) and
secured in that position by screws.
In Figures to 11 inclusive, the yielding material B is attached to strips A
secured to the window sashes or to the window frame in such a manner that it does
not prevent the window being opened. The strips may be fitted all round 'the
window as shown, and Figure 11 shows the yielding material and the strip on an
enlarged scale. The position of the strip can be adjusted by means of the slot a
and the screw a³. The strip A¹ to which yielding material is attached, (Figures 7
and 9) to exclude the draught which is liable to enter through the chink between
the two window sashes is made removable to permit the window sashes being raised
or lowered. a* is a pin screwed into one of the sashes and having an arm a adapted
to engage the strip A¹, and hold the yielding material down firmly over the chink
to exclude the draught. By rotating the said pin a half a turn, the strip A" is
released from the engagement of the arm a and the strip can then be removed to
enable the sashes to be opened.
The cushion B may if desired be used alone as a dust or draught excluder instead
of being applied to the backing A. In this case the baize or cloth b. Figure 11, is
attached direct to the window sash, window framing or the 'like by means of nails
or glue etcetera, without the intervention of the backing A.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. As an improved article of manufacture, a draught or dust excluder, comprising
a rigid backing or strip of wood or other suitable material, having a thin layer of
soft yielding material along one edge thereof, adapted to be placed upon or adjacent
to, the chink which it is desired to close, the said rigid backing being secured to
the door, window, drawer or other desired part by nails, screws, hinges or otherwise,
substantially as described.
2. As an improved article of manufacture, a draught or dust excluder, consisting
of a thick layer of untwisted cord of wool B or other suitable soft yielding material,
and a strip of cloth or baize b folded over the said material B and attached
to the door, window or other part by nails, glue or otherwise, substantially as
described.
3. The herein described draught or dust excluders for doors, windows, drawers
or the like combined and arranged substantially as set forth.
