Improvements in Fan Lights, Windows, Ventilators, and other
Closing Appliances.
1, GOTTFRIED STIERLIN of Schaffhausen, Switzerland, Machinist do hereby declare
the nature of this invention to be as follows :-
This invention is applicable to fan lights, windows, ventilators and other closing
appliances and consists in convenient means for rendering them self-closing while they
are also easily opened by pulling a cord, wire or chain connected thereto and from a
distance.
any
The window or fan light is mounted on spring hinges of suitable construction
and fitted so that the window has a tendency to shut. A peg fitted on one side of the
window and working in a slotted stop bar which is hinged to a bracket on the door
frame serves to limit the extent of opening of the window. But any other suitable
stop may be used and there may be a stop on each side. There is a bar which by a
pin is connected to a latch formed with a slot for the pin. The latch turns on a
fulcrum pin fitted with a spiral spring. To the bar is connected a wire, chain or cord
for opening the window or adjusting the amount of opening. This cord passes round
a small pulley which runs in a fitting hinged to the fan light. The spring on the
spring latch tends to throw it out to engage with a hook on the door frame. There
is a peg for putting one or other of the links of the chain on it and thus adjusting the
amount of opening of the fan light as desired. Any suitable spring latch may be
used.
By pulling the cord or chain while in a slanting direction away from the fan light
the latch is unlocked and the fan light at the same time pulled open to the desired
position or angle and held there by putting the corresponding link of the chain on to
the peg. When released therefrom the fan light will close of itself.

page_text: I, GOTTFRIED STIERLIN of Schaffhausen, Switzerland, Machinist, 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 :—
This invention is applicable to fan lights, windows, ventilators and other closing
appliances and consists in convenient means for rendering them self-closing while they
are also easily opened by pulling a cord wire or chain connected thereto and from a
distance.
In the accompanying drawings Figure 1 is a perspective view of a fan light
constructed according to my invention, the "light" or window being in the open
position whilst Figure 2 is a like view showing it in the closed position. Figure 3 is
a front view of the spring latch for holding the window in the closed position
Figure 4 a back view, Figure 5 a cross section of same and Figure 6 is a part
sectional side elevation to an enlarged scale showing a modification of the stop-bar E.
The window or fan light A is mounted on spring hinges CC of any suitable
construction and fitted so that the window has a tendency to shut. Referring to
Figures 1 and 2, B is a peg fitted on one side of the window and working in a slotted
stop bar E which is hinged to a bracket on the door frame D and serves to limit the
extent of opening of the window. But any other suitable stop may be used and there
may be a stop on each side.
Figure 6 shows a modified form of stop bar E which is pivoted to the fan light A
and has at its other end a stud B which works in a slot in the plate D¹ which is
screwed to the inside of the door frame D. When the fan light is provided with a
stop bar of this description the latter is hidden between the door frame and fan light
when said fanlight is shut.
F, Figures 3, 4 and 5, is a bar which by a pin f is connected to a latch G formed
with a slot for the pin. The latch turns on a fulcrum pin g fitted with a spiral spring.
To the bar F is connected a wire chain or cord H for opening the window or adjusting
the amount of opening. This cord H passes round a small pulley I which runs in a
fitting hinged to the fanlight. The spring on the spring latch tends to throw it out to
engage with a hook K on the door frame. L is a peg for putting one or other of the
links of the chain H on it and thus adjusting the amount of opening of the fan light
as desired. Any other suitable spring latch than the one shown may be used.
By pulling the cord or chain H while in a slanting direction away from the fan light
the latch G is unlocked and the fan light at the same time pulled open to the desired
position or angle and held there by putting the corresponding link of the chain onto
the peg L. When released therefrom the fanlight will close of itself.

page_text: 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 1 claim is :-
A window ventilator or other opening and closing appliance rendered self closing
by means of spring hinges and which is opened by means of a cord or equivalent
which on being pulled firstly unlocks the window and then opens it, said cord being
then fixed on to a hook or the like holding the window open to the extent desired
which is limited by a slotted hinged or other stop-bar substantially as described and
shown.
