Improvements in Apparatus for Opening. Windows Outside and
Inside of the Room.
I GUSTAV JOSEF DOLLINER Teacher of 24 Wexpassage Hamburg in the Free
State of Hamburg 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 this invention hereinafter described is to make windows in such a
way that they can be opened both inwards and outwards but at the same time to
combine this possibility with the condition of obtaining a completely air tight
connection between the window frame and the closed window casements.
In order to attain this purpose all the casements have two separate points of
rotation and in addition the double hinges of the casements are so made that the case-
ments when opened inwards descend and the lower window bar is made to take off so
that the casement provided with a stuffing bottom can be drawn inwards through the
space thus cleared.
The apparatus as applied to a window is shown on the accompanying drawings.
Figure 1 shows a view of the improved window as seen from the inside.
Figure 2 is a cross section through the window along the line X X of Figure 1.
Figure 3 is a horizontal section taken through the window in the direction of the
ines Y Y of Figure 1 with one casement opened outwards.
Figure 4 likewise shows a horizontal section taken along the line Y Y of Figure 1
with one casement of the improved window when the lower window bar a is taken out
and the casement b is opened inwards.
Figure 5 shows on a larger scale a section taken through the double hinge g of the
casement.
Figure 6 shows on a larger scale the special construction of the sockets cand e of
his double hinge in such a position that the slanting edges a' b¹ running one upon the
ther are just lying together a position which the parts assume when the window is
losed or opened outwards.

Figure 7 shows the position of the parts of the hinge Figure 6 at right angles to
the position of Figure 6.
Figure 8 shows the boxes or sockets of the hinge parts when the upper part c
thereof is slid down on the incline d of the lower socket'e so that the casement is
lowered to the height of its edge f down on the casement (Figure 2) a position which
is assumed when the window is opened inwards.
The casements bb are attached to the window frames h h by double hinges gg. The
window frame h h has at the bottom grooved surfaces ii on which the lower window
bar a is laid. The regular or irregular grooves i serve to prevent as much as possible
the draught getting into the room. The lower window groove a is made of two
parts a² as which are also provided with grooves at their corresponding adjoining
edges and fit into each other toothwise so that the entrance of draught is prevented.
The lower window bar fits in with its two curved ends a to the window frame h. In
this way a secure and excellent air tight and easily separable connection between the
window frame and the removable lower window bar is obtained. a³ is an appliance
for holding one casement so that the closed casements cannot fly outwards.
The casements are as already stated attached to the window frames by double
hinges 9999. These double hinges are shown on a large scale in Figures 5 to 8.
One flange of the hinge is attached to the inner side of the casement at g'. The other
flange gruns in a bent form to the outer side of the window frame h and there
-rotates about the binge-flange g fastened to the window frame.
...
If now one casement is to be opened it is turned about gs and pressed outwards
so that it comes into the position shown in Figure 3. If both the casements of one
window are thus moved outwards it is easy to take out the lower window bar a
separated into its two parts a a³. If it is now desired to open the windows inwards
they are turned about the part g as shown in Figure-4-and they can then be opened
inwards. The hinge parts with which the double hinges g are attached to the
windows have tubular sockets c (Figures 6 to 8), which for the greater part of their
circumference are cut off obliquely 'or spirally! The same applies to the tubular
sockets e of the hinge parts cut off obliquely at d. The object of this arrangement
is to lower the window to a certain extent while turning about the hinge gl, i.c. to
such an extent as the upper border amounts to on the casement. As appears from
Figures and 2 the casements are provided at f and k with borders the object of
which is 'to effect a secure air tight closure of the window against the window frame
or lower window bar a. The height of the upper border and the descent of the
casement on the oblique surface d are less than the height of the lower window groove
at the place of 'support of the casement. If now upon moving the outward-turned
casement inwards ie, from the position Figure 3 to the position Figure 4 the edge
of the case e on the casement comes beyond the edgela on the socket'e of the hinge
part the edge slides on the oblique surface'd of the hinge part g downwards and
consequently the casement & sinks a little more than the height of the border so
that the border of the window moved inward' comes and' lies 'inside the window
frante! The inward movement of the casement is thus in spite of the arrangement
of the borders and k rendered possible as soon as the lower window bar à is
ken
out of the window frame.
W
In order to prevent splash water from collecting on the windows and running down
them into the lower bar a and also to prevent the casetnents in winter from being
frozen in a channel is fitted to the inside of the window 'casements below the panes
which catches the water and prevents its running down into the lower grooved bar.
Between the casement and the window "frainé or the lower window bar india
Irubber or other packing can be placed for the purpose of tightening the casements.
