Improvements in and relating to Means for Opening, Olosing, and
Securing in Position Wings of Windows.
.
I, ROBERT WAGNER, of 20 Lunbacher Strasse, .Chemnitz, in the Kingdom of
Saxony, German Empire, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention refers to means for opening, closing, and securing in position
wings of windows, especially the upper one or ones, and my improvements in said
means relate to certain arrangements and combinations of parts, as is fully
described hereinafter. My invention is especially applicable to windows of that
kind, in which the wings are so arranged as to be adapted to be turned around a
horizontal axis, or with other words, in which the hinges are attached not to the
vertical but to the horizontal parts of the frames of the window and of its wings.
In windows of said latter kind, there are generally the hinges arranged at the
lower part of the wing or wings, so that the latter is or are opened at its or their
upper part or parts.
In one form of construction of my improved means for opening, closing, and
securing in position window-wings of the sort last mentioned I secure to the
uppermost (horizontal) part of the window-frame a spur-wheel arranged so as 'to
lie between the inner and outer wing in a horizontal position. A portion of said
spur-wheel is cut away, the line of cutting being straight and situated near to the
centre of said spur-wheel. The straight edge of the latter is directed to the inner
of the two wings just mentioned, and one or the other of the corners formed at
the ends of said straight cutting-line will thus push against, and push open, said
inner wing, if the said spur-wheel is rotated in one or the other direction.
To prevent the wing from falling completely open, the spur-wheel is opon its
lower surface provided with a curved ledge that forms a sort of bearing for a
steel-band secured at one end to the outer end of said ledge, and at the other end
to said wing. When, therefore, the latter has been pushed open by one or the
other of the corners afore mentioned, it is held by the said steel-band, and
is allowed by the same to swing down corresponding to the degree of rotation of said
spur-wheel.
In order to open also the outer wing of the double-window having the arrange-
ment afore described, the said wing is furnished with a longish projection, the
horizontal portion of which is provided with a slot. A pin fixed to the said
spur-wheel, and extending downwards from the same, takes into said slot. The
said pin is situated diametrically opposite to the straight cutting-line mentioned. If,
therefore, the spur wheel is rotated (the means for performing this will presently
be described), the said pin glides along within the slot of said angular projection,
and owing to its curved way draws the outer wing open. I prefer to let the pin
have a rather great length, so that also the outer wing may be opened to a rather
great extent. It is in this respect to be considered, that the said angular projection
is secured to the upper part of the said outer wing, and glides, therefore, downwards
along the said pin, if the respective wing is opened.
;

page_text: To operate the spur-wheel, I secure to the upper part of the window-fame a small
spur-wheel that is in gear with the large spur wheel described. The said small spur-
wheel is combined with a cord pulley. Two other parallel cord-pulleys are attached
to the side of said window-frame, and I then place an endless long cord about, and
around, the said three cord-pulleys, in such a manner, that the greater portion of said
cord hangs down at the respective side of the said window-frame.
Into the lower end of the said cord, I prefer to place a roll with a device tending
to keep the cord constantly strained.
Instead of making use of the ledge secured to the larger spur-wheel, and of the
steel-band arranged upon said ledge, I may as well directly connect the two wings by
a steel band, or by other suitable means. In one construction of this modified form, I
fix a hinge to one of said wings, and a hook to the other of the said wings, and
I then connect said two parts by a steel-band having at one end an ear, and being
at its other end screwed to the movable part of said hinge. The holes of said
steel-band (for letting the screws pass) may be widened so as to form slots allowing
of an adjustment of the said steel-band.

Improvements in and relating to Means for Opening, Closing, and
Securing in Position Wings of Windows.
I, ROBERT WAGNER, of 20 Lunbacherstrasse, Chemnitz, in the Empire of
Germany, Manufacturer of Iron Ware, 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 apparatus which enables the opening and closing of
sky-light windows to be effected by means of a cord, chain or the like.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Figs. 1, and 1A, show a side elevation.
Figs. 2, and 24, a front elevation, and
Fig. 3, a plan of the same.
Figs. 4, and 5, represent a plan and transverse section of an angle provided with
a slot.
In the frame a of the top window sash 6 I arrange the angle c at the top, as shown
in Figs. 1, and 2. In this angle is secured the bolt d, upon which I arrange the
semi-circular toothed wheel e so that it can turn. This wheel carries a pin f which
in the movement of the semi-circular toothed wheel e can move in the slot of an
angle g arranged on the top window sash b, as shown in Figs. 4, and 5.
The toothed wheel h, which is in connection with the toothed wheel e, is arranged
upon the bolt i likewise fixed in the angle c and is adapted to turn about the same,
as illustrated in Figs. 2, and 3. Above the toothed wheel h is a toothed disc k which
is firmly connected with the latter and can be moved by the chain l. The endless
chain, cord or the like l, as shown in Figs. 2, and 3, is passed over two
rollers m and m' which are arranged loosely upon a rod n. This rod n is held in
the angles o, and the latter are again secured in the window frame a. The
chain Figs. 14, and 24, is passed below over a roller p which is adapted to be
adjusted in the angle t by the block q, nut and thumb-nuts s. The angle is
likewise arranged on the window frame a.

page_text: 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. In an apparatus for closing sky-light windows, the combination of a semi-circular
toothed wheele and an angle c in the window frame and adapted to turn about a bolt d,
and a small toothed wheel h gearing with the aforesaid wheel and which is adapted to.
be moved by a chain, cord or the like, and the toothed wheel e being furnished with a
pin which can be moved to and fro in a slot formed in an angle arranged on the
upper window sash, and opens and closes the window sash by this movement,
substantially as herein described and according to the accompanying drawing.
2. In apparatus for opening and closing sky-light windows, the combination of the
various parts to form the said apparatus substantially as above described in this.
specification and illustrated on the accompanying drawing.
