1, JOHN ISAAC WILLIAMS, of 121 Kings Road, Chelsea, in the County of Middlesex,
Builder, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of metallic window sashes and
frames which will more effectually prevent the penetration of rain through the window
than the constructions heretofore employed, and in which also the glazing fillet is
fixed in such a manner that there are no external screw holes therein while the fillet
can adjust its position to suit varying thicknesses of glass.
For these purposes, instead of constructing the frame and sash of a simple angular
or trough shaped section so that when fitted together a rectangular hollow space is
enclosed between them, as heretofore, I construct the frame of a trough shaped
section with an overhanging flange or lip on the outer side, which lip has a hollow
throat on its under surface, and with a sloping rebate on the inner side, which is
higher than the outer side.
The sash is made of an augular section with a rib running along its inner side at
a short distance from the outer vertical face thereof, so that when the sash fits on
to the frame, the front vertical part of the former overlaps the front edge of the lip
of the latter, while the inner rib of the sash fits against the top face of the lip, and
thus forms the space between the sash and the frame into two separate compartments.
Thus any rain that may be blown in between the front part of the sash and the lip
of the frame is caught in the front compartment, from which it can afterwards be
drawn off again, while the second inner compartment is kept practically free from
water, or nearly so. The inner side of the sash is formed with a downwardly
projecting fillet with sloping edge which fits into the sloping rebate in the frame
and thus encloses the before mentioned inner compartment between the sash and
frame. The inner fixed fillet on the sash against which the glass fits and the outer
loose glazing fillet have both a shoulder at a certain distance from the bottom, so that
when the glass and loose fillet are placed in position, the glass rests upon the said
shoulders of the two fillets, leaving a certain space between it and the bottom, so that
for securing the loose fillet screws can be passed from the inside through the fixed

page_text: fillet and through the space beneath the glass so as to screw into a tapped hole in the
loose fillet, and thus it will be seen that the loose fillet can be drawn in to a greater
or less extent by the screws according to the thickness of glass employed.
In the jambs of the window opening are formed grooves in which are secured
metal fixing fillets that have a projecting bead on their outer edge so that when the
window frame is fixed in position its sides buit against the projecting beads of the
fixing fillets, thus forming a watertight joint therewith.
On the upper side of the window opening is fixed a weather bar formed of a thin
plate having a rib projecting from each side thereof, the one rib being fixed into a
groove in the masonry, while the other forms an abutment for the inetal window
frame.
When applying this invention to casements opening on hinges, I form the hinge
so that the one leaf thereof fits against the inner surface of the before mentioned
front vertical part of the sash bar, to which it is fixed by screws screwed in from
the inside, while the other leaf is fixed to the face of the frame forming the bottom
of the trough shaped hollow. Thus the hinges are entirely concealed from the out-
side. The centre of the hinge is so arranged that on opening the casement, the
edge of the sash passes into the space between the lip of the frame and the window
jamb.

page_text: I, JOHN ISAAC WILLIAMS of 121 Kings Road Chelsea in the County of Middlesex
Builder 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:--
My invention relates to an improved construction of metallic window sashes and
frames which will more effectually prevent the penetration of rain through the
window than the construction heretofore employed, and in which also the glazing
fillet is fixed in such a manner that there are no external screw holes therein while
the fillet can adjust its position to suit varying thicknesses of glass.
For these purposes instead of constructing the frame and sash of a simple angular
or trough shaped section so that when fitted together a single rectangular hollow
space is enclosed between them, as heretofore, I construct the frame of a trough
shaped section with an overhanging flange or lip on the outer side, and with a sloping
rebate on the inner side, which is higher than the outer side.
The sash is made of an angular section with a rib running along its inner side at
a short distance from the outer vortical face thereof, so that when the sash fits on to
the frame, the front vertical part of the former overlaps the front edge of the lip of
the latter, while the inner rib of the sash fits against the top face of the lip, and thus
forms the space between the sash and the frame into two separate compartments.
Thus any rain that may be blown in between the front part of the sash and the lip
of the frame is caught in the front compartment, from which it can afterwards drain
off again, while the second inner compartment is kept practically free from water or
nearly so.
The inner side of the sash is formed with a downwardly projecting fillet
with sloping edge which fits into the sloping rebate in the frame and thus encloses
the before mentioned inner compartment between the sash and frame. The fixed
fillet on the sash against which the glass fits has a shoulder at a certain distance from
the bottom, so that when the glass and loose fillet are placed in position, the glass
rests upon the said shoulder of the fixed fillet leaving a certain space between it and
the bottom, so that for securing the loose fillet screws can be passed from the inside
through this fillet and through the space beneath the glass so as to screw into a
tapped hole in the fixed fillet and thus it will be seen that the loose fillet can be
drawn in to a greater or less extent by the screws according to the thickness of glass
employed.
In the jambs of the window opening are formed grooves in which are secured
metal fixing fillets that have a projecting head on their outer edge so that when the
window frame is fixed in position its sides butt against the projecting beads of the
fixing fillets, thus forming a watertight joint therewith.
On the upper side of the window opening is fixed a weather bar formed of a thin
plate having a rib projecting from each side thereof, the one rib being fixed into
a groove in the masonry, while the other forms an abutment for the metal window
fraine.
When applying this invention to casements opening on hinges, I form the hinge
so that the one leaf thereof fits against the inner surface of the before mentioned
front vertical part of the sash bar to which it is fixed by screws screwed in from the
inside while the other leaf is fixed to the face of the frame forming the bottom of the
trough shaped hollow. Thus the hinges are entirely concealed from the outside.
The centre of the hinge is so arranged that on opening the casement, the edge of the
sash passes into the space between the lip of the frame and the window jamb.

page_text: Fig. 1 of the accompanying drawing shews a horizontal section through my
improved window sash and its frame fixed in position. Fig. 2 shews the same
section fitted with a hinge, Fig. 3 shews a section of the sash by itself and Fig. 4
shews a section of the frame by itself. Fig. 5 shews a vertical section through the
sash and frame and Fig. 6 shews it fitted to the sill at bottom.
The sash frame A has a groove a and an overhanging lip with or without a hollow
on its underside, so as to form a drip, when forming the bottom of the frame, as at
Fig. 6 the upper surface e as also the surface d of the rebate are sloped outwards.
A groove is formed at e into which fits the projecting bead of the fixing fillets B let
into the jambs, and also the bead of the weather bar let into the head of the window.
The groove e for the fillet B is made of some depth as shewn so as to allow of
adjustment, the space if any, between the groove and the fillet being filled with
cement.
The sash D is formed with its front part to overlap the lip of the frame, and it
has an inner rib g that fits upon the sloping surface of the lip, whereby the space
between the sash and the frame is divided into two cavities, so that should any rain
penetrate between the part and the lip bit will be caught in the front cavity, from
which it can escape at the ends; should any small quantity of water penetrate between
the rib g and the lip, this will be caught in the inner cavity of the frame, from which
it can also escape at the ends. The inside face of the sash is provided with a rib h
that fits into the rebate of the frame so as to enclose the inner cavity as shown. It
will be seen that this construction of sash affords considerable strength as compared
with the sections now employed. E is the loose glazing fillet, which fits with pro-
jecting rib against the glass; the fixed outer fillet F is formed with a shoulder upon
which the glass rests as shewn, thus leaving a space between it and the bottoms of
the fillets through which screws G can be passed from the inside of the sash screwing
into threaded holes in the outer fillet F so that the position of the glazing fillet is
always adjusted by the screw according to the thickness of the glass. Fig. 2 shews
the manner in which the sash D is attached to the frame A by hinges. Part of the
lip bis cut away for this purpose and the one leaf H of the hinge is fixed by screws
to the frame, while the other leaf' H' is fixed to the sash, the hinge being thus entirely
hidden.
The centre pin J is in such a position that the edge off will pass into the space
between the lip b and the jamb when the window is opened.
The weather bar C, instead of being a flat plate as heretofore constructed has a
projecting outer fillet i against which the groove e of the frame fits.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In metallic window sashes and frames the combination of a frame A having a
groove a and an overhanging lip with a sash D fitting with a rib in the rebate of
the frame and with a second rib g that fits against the surface c of the frame, while
a front rib overhangs the lip 6 of the frame, whereby considerable strength is afforded
and two enclosed spaces are formed between the frame and the sash, substantially as
and for the purposes herein described.
2. The use in combination with a metallic window sash, of a loose glazing fillet E
so arranged that it can be adjusted in position by screws G passing between the edge
of the glass and the sash substantially as herein described.
