Improvements in Swinging Windows.
I, CARL REINHARDT, Architect of 88/89 Sedanstrasse, Schöneberg near Berlin
in the Empire of Germany, 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 present invention relates to improvements in swinging windows and has for
its objects: 1) To automatically fix the window in any position, 2) to protect the
wedge shaped side openings of the window frame from letting in rain and wind,
3) to protect the opening between the bottom of the window frame and the
casement in similar manner, 4) to protect the window frame from warping or
bending..
1. In order to be able to open the window and leave it in any position it is
connected to the brickwork by a three part curved toothed rod which by means of
toothed wheels and a chain can be extended or closed up. This arrangement is
shown in the Figures 1-7.
The Figures I and 1^ show on a small scale the general arrangement-in the
former case the tootlied rod lays in the centre, and in the latter case at the side..
Figure 2 shows a view of the three part rod on a larger scale.
Figure 3 is a horizontal section on the bent line -x of Figure 2.
Figure 4 shows a top view of the rod with the window.closed.
The Figures 5 and 6 are part horizontal sections of the two parts of the rod
in different positions relatively to each other and Figure 7 is a section through
the rod.
f
The front bend a' of the toothed rod is connected to the window cat b (Figures 1
and 2). When the window is shut the three parts of the toothed rod a¹ a² a lay
close to each other in the channel d of the casement e (Figure 4). The front and
back sections a¹ and a³ are provided with curved slots whilst to the central section
are fitted the two guide projections g with wide top plates y'. The projections g
are fixed to the two ends of the toothed sections a² one on the front side and the
other on the back. The projections engage in the slots f. The ends or bearing
surfaces of the two connected toothed sections are formed into the sloping surfaces /
which bear on each other when the window is open. Corresponding to the surfaces h
are the sloping running surfaces of the slots for the guide plate g' of the pro-
jection g. The small wheel i engages in the toothed rod and on its spindle is the
chain wheel. The latter is worked by an endless chain k.
In opening the window the small pin wheel i moves the toothed sector a¹ out of
the channel d until its sloping running surfaces h¹ (Figures 4 and 6) meet the top
plate g' of the front projection g of a², slide underneath them, and thereby, move
the sector a sideways into the working plane of the wheel i, whereby the sector a³
is moved into the plane previously occupied by a². By further rotation i engages
over a² and pushes this forward until the top plate g₁ of its lower projection g meets
the sloping running surfaces of the third toothed sector a³, runs under it, and
moves a into the plane of the wheel i, whereby a is then engaged by the pin
wheel until the window is entirely open, In closing the window the process is
reversed. The wheel i holds the closing rod, and in consequence, the window also
in any desired position.
2. In order to protect the wedge shaped side openings of the window from the
penetration of wind and rain, which is of great sanitary importance for infirmaries
and schools, side protector pieces are arranged, movable over each other like a fan
and movable with the window in the same manner as described under (1). This
arrangement is shown in the Figures 8-13.

Figure 8 shows the whole arrangement on a small scale with open window.
Figure 9 shows on a larger scale.a view of the top part of the fan-like projecting
pieces.
Figures 10 and 11 are horizontal sections on the bent lines y-y and -—
respectively of Figure 9.
Figure 12 is a section on ww of Figures 10 and 11.
Figure 13 is finally the top view of the fan-like protector with closed window.
The fan-like protecting pieces on both sides consist of the three plates 11
which at the bottom are movable about a common rotating pin m (Figure 8). At
the top these plates are provided with bent strengthening rims n' n n of which
the front one'n' is fixed to the window. On the one side of the window the
rims n¹ n² n³ are provided with teeth, in which the wheel i engages. The latter is
put in motion by the chain wheel and endless chain k. The rims n' n² n³ are
cut off at a sloping angle at those ends where, with the window open, they bear
on each other (Figures 11 and 13). The plates are bent at their lower ends
(Figure 10) so that they can lay in the same plane. The front and back plates !!
and are provided with longitudinal slots o and a wedge with sloping surface pl
whilst the middle plate 2 carries the guide rod g with a wide top plate q'.
P
When the window is closed the plates lay alongside each other in a channel r
in the brickwork. In opening the window the wheel i moves the plates out one
after the other whereby the top plates q' run over the wedge surfaces p' and force
the following plate into the plane of the wheel i so that it may engage in the
toothed gear thereof. In closing the window the process is reversed, the sloping
bearing surfaces of the rims n² m² n³ effecting the side movement of 2 and 13. The
plate remains always in the same plane. Instead of the wedge shaped pressing
arrangement, 2 and 3 can be arranged somewhat inclined so that on the preceding
plate moving out, the next plate moves itself over into the same plane.
3. In order to prevent the penetration of wind rain and dropping water through
the openings forined between the hung window and the frame when the window is
open, the protecting plate u is nailed underneath the water nosing t and completely
covers the opening, (see Figure 14, which shows on a large scale a vertical section
on the line of Figure 8). The position of the protecting plate with the
window closed is shown in dotted lines. This arrangement is a development of the
side protecting pieces described under 2.
4. In order finally to protect the wood frame of the window from warping or
bending, a hoop shaped metal frame (Figure 15) is let into the wood or screwed
thereon from the back. The lower piece v of this hoop is shown in section in
Figure 14. The side pieces enclose the side frames of the window as shown in
Figure 8.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The arrangement of apparatus for opening, closing, and securing swinging
windows comprising a curved and toothed rod connected to the window sash and
constructed in several parts and being operated by a pin wheel in such manner
that when the sash is open they form one continuous rod; but which when the
sash is closed are automatically deposited side by side in a recess or receptacle
substantially as described.
2. The arrangement and construction of apparatus for opening, closing, and,
securing swinging windows substantially as described with reference to Figures 1-7
of the drawings.
3. The arrangement of apparatus for protecting the side openings of swinging
windows from the penetration of rain and wind consisting of rotary sliding plates
connected to the sash frame and to the toothed operating rod and which open and
close with the window, and when closed are automatically deposited side by side in
a recess or receptacle substantially as described.

openings of swinging windows of the kind specified substantially as described with
reference to Figures 8-13 of the drawings.
5. The arrangement to protect the space between the sash frame and the
window frame from the penetration of rain, dropping water and wind, by a pro-
tecting plate (u) fastened under the weather nosing (t) and which covers the
opening substantially as described.
6. The arrangement to protect the frame of the lifting window from bending or
warping, consisting of an iron hoop shaped frame (v¹³) let into the wood or
screwed on from the back substantially as described.
