Improvements in and relating to Window-sashes.
I, MARTIN KIEN, of 43, Baumgasse, Vienna III, in the Empire of Austria,
Cabinet-Maker, do hereby declare the nature of this invention to be as follows:-
The essential feature of the window-sash construction forming the subject of my
invention, consists in that the parts of the frame or sash are connected together
at the corners by angle-shaped sleeves of channel or U-shaped cross-section made
in one or more parts, and the said sleeves are connected with the parts of the frame
or sash by screws passing through both side walls of the sleeves and through the
parts of the frame or sash and fixed by nuts arranged in the interior of the said
parts.
In carrying my said invention into practice according to one method the window-
sash parts are connected together at the corners by angle-shaped sleeves of channel
or U-shaped cross-section made in one piece. Preferably the longitudinal openings
in the said sleeves are provided with inwardly-extending strips or ribs which secure
the two parts in the sleeve and permit an union of these two parts by simply
sliding them in, during which operation the said parts can be firmly pressed
together by making the said inwardly-turned ribs or strips somewhat tapering.
The connecting pieces at the corners are also provided with external strips like
the parts of the frame or sash adjacent thereto, which strips serve as supports for
securing the glass by means of a fillet of putty.
The connection of the sleeve with the parts of the frame or sash is effected by
screws or bolts, which are only provided with screw-threads in the middle, and are
connected by means of these threads with nuts mounted within the wood of the
frame or sash, the end of the smooth part of the screw extending through the wall
of the sleeve and only serving as a guide.
If desired, the sleeve can be made in two parts, which may or may not abut
together in the middle line of the cross-section and are connected by screws with
the parts of the frame lying between them.
Moreover, according to my said invention, packing is arranged between the
window-sashes and the sash-frame, which completely prevents the entrance of dust
and water even with windows which otherwise would not close tightly; this pack-
ing consists of a piece of elastic material which is of tubular or other suitable form
and is secured in a suitable groove in the window-sash by any suitable cement or
binding material.
The advantages of my improved connection consist in that it is very durable, in
addition to permitting the employment of a less thickness of wood, whereby
shrinkage in drying takes place to a considerably less degree than when broader
and thicker wood is employed; further in that, only bevelled wood need to be used,
so that the upright front pieces of wood are covered by the transverse pieces and
are therefore protected against moisture and dirt. Moreover the window-sashes

page_text: can be more readily made tight, even without packing, than when employing parts
of larger dimensions.
The screw-connection above mentioned affords the advantage that the wood does
not need to be provided with screw-threads and the frame or sash is therefore more
durable, further, that in the drying and shrinkage of the parts, the screw-bolts
only require to be tightened up in order to obtain, at this stage, a firm abutment
or tightening of the parts against each other, or, at least, against one side of the
sleeve and to ensure that the glass-retaining ribs or strips of the latter shall be
level and in continuous connection on both sides, this being effected by the screw
passing through the same, thus stiffening the parts.
In cases where the sleeve is made in two parts, a screw connection of this kind
is not necessary, since in this arrangement, should the wood dry, the two halves can
be brought together and the frame parts lying between them thus tightly clamped
by tightening up the screws inserted into the sleeve,

1, MARTIN KIEN, .of 43, Baumgasse, Vienna III, in the Empire of Austria,
Cabinet-Maker, 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 essential feature of the window-sash construction forming the subject of
my invention, consists in that the parts of the frame or sash are connected together
at the corners by angle-shaped sleeves of channel or U-shaped cross-section made
in one or more parts, and the said sleeves are connected with the parts of the frame
or sash by screws passing through both side walls of the sleeves and through the
parts of the frame or sash and fixed by nuts arranged in the interior of the said
parts.
In the accompanying drawing are shown two forms or modifications of my
improved window-frame construction,
Figures 1 and 2 showing one form in transverse section and elevation respec-
tively, and
Figures 3 and 4 the other similarly in transverse section and elevation.
The window-sash shown in Figures 1 and 2, consists of the frame members or
parts a, b which are connected together at the corners by angle-shaped sleeves c
of channel or U-shaped cross-section made in one piece. Preferably the longi-
tudinal openings in the said sleeves are provided with inwardly-extending strips
or ribs which secure the two members or parts in the sleeve and permit an unión
of these two parts by simply sliding them in, during which operation the said
members or parts can be firmly pressed together by making the said inwardly-
turned ribs or strips & somewhat tapering, as shown in dotted lines in Figure 2.
The connecting pieces at the corners are also provided with external strips like
the parts of the frame or sash adjacent thereto, which strips serve as supports for
securing the glass m by means of a fillet of putty 7.
The connection of the sleeve with the parts of the frame or sash is effected by
screws or bolts e, which are only provided with screw-threads in the middle, and
are connected by means of these threads with nuts f mounted within the wood of

page_text: the frame or sash, the end of the smooth part of the screw extending through the
wall of the sleeve and only serving as a guide.
The sleeve shown in Figures 3 and 4 only differs from that above described in
that it is made in two parts g and h, which may or may not abut together in the
middle line of the cross-section and are connected by bolts or screws with the
parts of the frame or sash lying between them.
Moreover, according to my said invention, packing is arranged between the
window-sashes and the sash-frame, which completely prevents the entrance of dust
and water even with windows which otherwise would not close tightly; this pack-
ing, as shown in the drawing, consists of a piece of clastic material which is
of tubular or other suitable form and is secured in a suitable groove in the window-
sash by any suitable cement or binding material.
The advantages of my improved connection consist in that it is very durable, in
addition to permitting the employment of a less thickness of wood, whereby shrink-
age in drying takes place to a considerably less degree than when broader and
thicker wood is employed; further in that, only wood cut to a mitre or bevel need
be used, so that the upright front pieces of wood are covered by the transverse
pieces and are therefore protected against moisture and dirt. Moreover the window-
sashes can be more readily made tight, even without packing, than when employing
parts of larger dimensions.
The screw-connection employed in the arrangement shown in Figures 1 and 2,
affords the advantage that the wood does not need to be provided with screw-
threads and the frame or sash is therefore more durable, further, that, in the drying
and shrinkage of the parts, the screw-bolts only require to be tightened up in order
to obtain, at this stage, a firm abutment or tightening of the parts against each
other, or, at least, against one side of the sleeve and to ensure that the glass-
retaining ribs or strips of the latter shall be level and in continuous connection
on both sides, this being effected by the screw passing through the same, thus
stiffening the parts.
In the arrangement shown in Figures 3 and 4, a screw connection of this kind
is not necessary, since in this case, should the wood dry, the two halves 9 ½ can
be brought together and the frame parts lying between them thus tightly clamped
by tightening up the screws inserted into the sleeve.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is;
1. The improved sash-frame provided with angular corner connecting-pieces
made of channel or U-shaped cross-section in one or more parts, substantially as
described.
2. In a sash-frame such as is hereinbefore described, a screw-connection between
the corner connecting-piece and the adjacent parts of the sash comprising a screw
or bolt the nut of which rests in the adjacent part or member of the sash, as set
forth.
