We, HENRY BYWATERS, Builder, of No. 10 King Street, Regent Street Loudon, W.,
and WILLIAM HENRY. TABOR, Joiner, of No. 46 Ashford Street London, N.,
do hereby declare the nature of our Invention for the "IMPROVED DRAUGHT-TIGHT
WEATHER-BAR to be as follows, viz. :—
"
"This our invention consists of a T shaped weather-bar, of metal, wood, or other
hard material, to be inserted in a groove in the sill or transome of the frame of
any sash, casement, door, fanlight, or flap which is hung by hinges, on centres, or
otherwise, and opening inwards.
A portion of the web of weather-bar is inserted in the sill or transome of the frame,
the upper flange being shaped or weathered outwards and the inner part of flange
shaped as bead, to fit closely into portion of bottom rail of the sash, casement, door,
fanlight, or flap shutting against it. The under portion of this bottom rail is rebated
and throated, the throated portion projecting outwards over the weather bar, the
inner or lower part of rail fitting closely as before mentioned to bead of
weather bar.
This we claim as making a simple and effective "Draught-tight weather bar" to
casements, doors, sashes, fanlights, or flaps, as herein before described.

COMPLETE SPECIFICATION.
Improved Draught-tight Weather-bar.
We, HENRY BYWATERS, of 10, King Street, Regent Street, Builder, and WILLIAM
HENRY TABOB, of 46, Ashford Street, Hoxton, Joiner, both in the county of
London, 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 weather-bars for casement doors and windows, fan-lights
or flaps and the like which are hung by means of hinges or on centres or otherwise
and opened inwards, and has for its object to provide a bar which will exclude
draught and rain more effectively than bars as hitherto constructed.
Our improved weather-bar which is made of metal or other suitable hard material
comprises a web for supporting the bar on the sill and having projecting therefrom
on one side a flange and on the other a bead, which latter is adapted to enter a
corresponding groove in the bottom rail of the casement door, window or the like.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawing, in which―
Figure 1 is a transverse section of a weather-bar constructed according to our said
invention; and
Figure 2 is a sectional view through the lower part of a casement door and frame,
the latter being provided with our improved weather-bar.
a is our improved weather-bar which is formed with the web b, the flange a
and the bead à; e is the sill or transom of the frame and f the bottom rail of the
casement.
In applying our weather-bar to a door or the like a groove or recess is formed in
the sill or transom into which the web b is inserted in such a manner that the flange c
projects towards the outside. The bottom rail of the door or window shutting
.

page_text: against the said bar is grooved as shown so as to fit tightly over the bead d to
prevent draught; and the under portion of the said rail is rebated or throated in the
portion projecting outward over the weather-bar, for instance as at g to prevent water
from dripping onto the flange c.
To provide against any water entering between the door, window or the like and
the weather bar the flange c is preferably rebated as at h so as to form a ledge i.
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
1. A weather-bar formed with a web having a flange projecting therefrom on one
side and a bead on the other, substantially as described.
2. The manufacture and use of the improved weather-bar hereinbefore described
and illustrated in the accompanying drawing.
