Improved Means for Forming Water Tight Joints for Doors and
Windows.
I, JOSEPH GETS, of Brussels in the Kingdom of Belgium do hereby declare the
nature of this invention to be as follows
This invention relates to improved means for forming water tight joints between
the bottom rails of doors and of french windows and their sills. For this purpose the
overhanging nose of the bottom rail of the door or window has a groove formed on
its underside, into which, when the door or window is closed, fits the upper end of a
curved metal plate extending along the sill and pivotted thereto, the plate being of
such a width that while its upper edge fits against the side of the said groove, its
lower edge overlaps the edge of the sill, and thereby effectually covers the joint of the
door or window with the sill against the entrance of water. The door or window is
provided with means whereby, in the act of closing the same, the said plate is raised
into the position described while in opening the door or window the plate is allowed
to drop out of the groove of the overhanging nose and thus allows it to move back
with the door or window,
This may be effected either by providing on the vertically sliding bolt of the door or
window, when such is used, a rod that passes down through a hole in the bottom rail
and comes in contact with the one end of a double ended lever whose other end
bears against the under side of the before mentioned pivotted guard plate, so that
when after closing the door or window the fastening bolt is slid downward, the rod
depresses the one end of the lever and causes its other end to raise the guard plate.
On raising the bolt for opening the door or window the rod releases the lever and this
allows the guard plate to drop. According to another arrangement, applicable to any
mode of fastening the door or window, there are provided on the bottom rail, slightly
below the before mentioned overhanging nose, one or more projecting studs which,
on the closing of the door or window presses against the back of the guard plate and
so pushes it into the raised position, while on opening the door or window the stud
allows the plate to drop again.
Instead of making the abutting surfaces of the door and its sill and frame plane
surfaces as heretofore, I form the same with an ogival or S shaped curvature, so that

page_text: when these surfaces are pressed together they are sure to meet at some part or other
of the curvature and thus insure a more perfectly water-tight joint than with flat
surfaces. When the door or window has a wooden sill fitted on to a stone sill, I make
the former with the usual longitudinal groove or gutter below the lower edge of the
door or window rail for the reception of any water that may leak through, and with
a channel passing from this in a forwardly sloping position through the wood sill to a
part of the underside thereof which overhangs the sunk sloping part of the stone sill,
so that any water leaking through into the said gutter will readily drain off to the
outside again, and I fix in the under surface of the overhanging part of the wood sill
a metal shield, passing down to near the surface of the stone sill, so that while it allows
the beforementioned leakage water to flow away, it prevents the rain from being
driven by the wind inwards between the joints of the wood and stone sill or up the
beforementioned channel.

Improved Means for Forming Water Tight Joints for Doors and
Windows.
I, JOSEPH GETS of Brussels in the Kingdom of Belgium 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 statenient :-
My invention relates to improved means for forming water tight joints between
the bottom rails of doors and of french windows and their sills. I will describe
the appliance which I use for this purpose referring to Figs. 1 and 2 of the accom-
panying drawings which are part sections of the lower part and sill of a door or
french window, Fig. 3 being a front view. The overhanging nose of the bottom
rail of the door or window has a groove formed on its underside, into which when the
door or window is closed, fits the upper end of a curved metal plate A extending
along the sill and pivotted thereto, the plate being of such a width that while its upper
edge fits against the side of the said groove, its lower edge overlaps the edge of the
sill as shown in Fig. 2 and thereby effectually covers the joint of the door or window
with the sill against the entrance of water. The door or window is provided with
means whereby, in the act of closing the same, the plate A is raised from its recum-
bent position shewn in Fig. 1 to that shewn in Fig. 2, whilst in opening the door
or window the plate A is allowed to drop out of the groove without interfering with
the opening of the door or window.
This may be effected by providing as shewn in Figs. 1 and 2 on the vertically
sliding bolt D of the door or window, when such is used, a rod C that passes down
through a hole in the bottom rail and comes in contact with the one end of a double
ended lever B whose other end bears against the underside of the pivotted guard
plate A, so that, when after closing the door or window, the fastening bolt is slid
downwards, the rod C depresses the one end of the lever B and causes its other end
to raise the guard plate A. On raising the bolt for opening the door or window the
rod C releases the lever B and this allows the guard plate A to drop. According to
another arrangement, shewn in Figs. 5 and 6, applicable to any mode of fastening
the door or window, there is provided on the bottom rail slightly below its over-
hanging nose, a projecting stud F which on the closing of the door or window
presses against the back lip of the guard plate A and so pushes it into the raised
position, whilst, on opening the door or window the stud F allows the plate A to
drop again.
Instead of making the abutting surfaces of the door and its sill and frame plane
surfaces as heretofore, I form the same as shewn in Fig. 4 with an ogival or S shaped
curvature at S so that when these surfaces are pressed together in closing the door or
window T they are sure to meet at some part or other of the curvature S and thus
insure a more perfectly water tight joint than with flat surfaces. When the door or
window has a wooden sill fitted on to a stone sill, I make the former with the usual

page_text: longitudinal groove or gutter G below the lower edge of the door or window rail
for the reception of any water that may leak through, and with a channel H passing
from this in a forwardly sloping position through the wood sill to a part of the
underside thereof which overhangs the sunk sloping part of the stone sill K, so that
any water leaking through into the gutter G will readily drain off to the outside
again; and I fix in the under surface of the overhanging part of the wood sill a
metal shield L passing down to near the surface of the stone sill so that while it.
allows the before mentioned leakage water to flow away, it prevents the rain from
being driven by the wind inward between the joint of the wood and stone sill or up
the sloping channel H.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. In combination with a door or french window and its sill a pivotted guard
plate A, and lever B and bolt rod C for raising it, substantially as described with
reference to Figs. 1 and 2.
2. In combination with a door or french window and its sill a pivotted guard
plate A and stud F for raising it, substantially as described with reference to
Figs. 5 and 6.
3. The construction of wooden sill with gutter G sloping channel H and shield L
substantially as and for the purposes set forth.
4. Forming the meeting faces of a door edge and of the rebate against which it
closes with an ogival curvature S as and for the purpose stated with reference to
Fig. 4.
