IDIONAL SPECIFICATION.
Improved Dust, Rain, and Draught Preventer for Window Sashes or
Frames, Doors, Lids, and the like.
I, GEORGE CHADWICK KINGSBURY, of 3 Brighton Parade, Blackpool, Doctor
of Medicine, do hereby declare the nature of this invention to be as follows:-
The object of the improvements is to provide means to be fitted to window sashes
or frames or to doors, or box or other lids, for the purpose of more effectually
excluding dust, rain, or draughts of air.
To accomplish this and to effect my improvements, I prepare strips of india
rubber, or rubber compound, or similar or other composition, and combined or not
with textile fibre, of suitable thickness, and of such length and width as shall be
found desirable, for the purpose to be hereinafter described.
Each of these strips of rubber, or composition, I form on one side with one or
more channels or serrations therein, either zigzag or wave-like in cross-section, or
of other similar formation, running lengthwise of the strip
In the case of a house window, I attach one or more of these strips, of the desired
length and width, by screws, nails, glue, or other suitable means, to the bottom of
the lower window sash, or top of the upper sash or both, with the smooth or flat
side to the wood-work; and in similar manner attach another strip to the window
frame, in such a way that when the window is closed, the projections on one rubber
strip face take into corresponding channels or depressions in the strip on the window
frame, and so prevent the inrush of air and rain which so often occurs in the case
of ordinary window sashes as at present constructed.

In applying my improvements to doors, I attach a length of the prepared rubber
trip to the inner edge of the door post, and another like strip on the edge of the
ace of the door, so that, as in the case of windows, the projections and depressions
ill fit into each other, and so prevent draughts.
In the case of the doors or lids of boxes, safes, wardrobes, and other receptacles,
he strips may be contained all round the edges thereof.
Further variations in detail may be made, such as the form of the serrations or
annels in the rubber strips, and the number and size thereof, together with the
aterial of which such strips are made, also in their application, without departing
om the peculiar character of the invention.

Improved Dust, Rain, and Draught Preventer for Window Sashes or
Frames, Doors, Lids, and the like.
I, GEORGE CHADWICK KINGSBURY, of 3 Brighton Parade, Blackpool, Doctor
of Medicine, 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:-
The object of the improvements is to provide means, to be fitted to window sashes
or frames, or to doors, or box or other lids, for the purpose of more effectually
excluding dust, rain, or draughts of air.
To accomplish this, and to effect my improvements, I prepare strips of india-
rubber, or rubber compound, or similar or other composition, and combined or not
with textile fibre, of suitable thickness, and of such length and width as shall be
fourd desirable, for the purpose to be hereinafter described.
Each of these strips of rubber, or composition, I form on one side with one or
more channels or serrations therein, either zigzag or wave-like in cross section, or
of other similar formation, running lengthwise of the strip.
In the case of a house window, I attach one or more of these strips, of the desired
length and width, by screws, nails, glue, or other suitable means, to the bottom of
the lower window sash, or top of the upper sash, or both, with the smooth or flat
side to the wood-work; and in similar manner attach another strip to the window
frame, in such a way that when the window is closed, the projections on one rubber
strip face take into corresponding channels or depressions in the strip on the window
frame, and so prevent the inrush of air and rain which so often occurs in the case of
ordinary window sashes as at present constructed.
In the case of carriage windows, the attachment may be applied to the top of
the sash only.
In applying my improvements to doors, 1 attach a length of the prepared rubber
strip to the inner edge of the door post, and another like strip on the edge of the
face of the door; so that, as in the case of windows, the projections and depressions
will fit into each other, and so prevent draughts.
In the case of the doors or lids of boxes, safes, wardrobes, and other receptacles,
the strips may be continued all round the edges thereof.
I am aware that single strips of tubing of rubber or the like have been employed
for a similar purpose, but such are entirely different from this my present invention,
which mainly consists in the attachment to window sashes, doors, lids, and the
like, of double strips, having formed therein or thereon longitudinal serrations,
channels, or grooves, the projections on one strip taking into the depressions on
the other.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.

the relative positions of the strips on the window sash and frame,
that when the window is shut, the projecting portions of the one strip, fit into the
recesses of the other strip, as shown in Fig. 2; and an approximately air tight
joint is made for the prevention of draughts and entrance of dust and rain.
Although the rubber or other strips are shown in the drawing attached to one
form of window only, it is obvious that the same may be applied at the top, bottom,
sides, or one or other thereof, to all kinds of house, carriage, or other windows, that
are made to open and shut, such as, for instance, the windows of public and private
road vehicles, of railway carriages, and of public buildings. The strips may also be
used in conjunction with doors, and the lids of boxes, and other receptacles, whether
arranged to slide as shown, or to close by turning on hinges.
Different modes of attaching the strips may be adopted according to the nature
of the substance to which the strips are to be applied; either by the use of cement,
glue, screws, nails, or otherwise; and further variations in detail may be made, such
as the form of the serrations or channels in the rubber strips, and the number and
size thereof, together with the material of which such strips are made, without
departing from the peculiar character of the invention.
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 :-
The combination of india-rubber or other strips of the particular character
ereinbefore described, with window sashes and frames or doors, and the lids of
oxes and other receptacles, for the purpose of excluding dust or moisture, and
reventing draughts, in the manner substantially as herein shown and described.
