Improvement in Skylights.
I, KASPAR HÜRTGEN, Work-master of Lindenthal, Bachemerstrasse, near
Cologne in the Province of Rhineland and Kingdom of Prussia 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 skylights in use up to the present have the drawback that they must of
necessity be closed in rainy or snowy weather etc., because otherwise rain, snow etc.
would enter into the interior of the house through the opening of the window,
while on the one hand it would often be of advantage even during such bad
weather to air the rooms and therefore to keep open the skylights, and on the other
hand people often forget to close the skylight when bad weather sets in, it often
happening, that no one is there to do so.
My skylights are intended to do away with these disadvantages.
Such a window is represented in the accompanying drawing in Fig. 1 in a
section to -y of the Fig. 2, in Fig. 2 in an upper view, the window being closed,
in Fig. 3 in a side-view and in Fig. 4 in a section to - of the Fig. 1.
The skylight consists of several parts, the frame A, the actual skylight B, con-
taining the pane, and several equally large window-less frame-pieces CC₁ C, etc.
moveably attached to the inclined rim r of B near the hinder or upper end by
being strung on two common rods a a (Fig. 3) and fitting into this rim."
These frame-pieces are connected with B and with each other in such a manner
by a chain K towards the front or lower end of the window, that, when B is
pushed up, i.e. is opened, they are raised one after the other at equal distances from
each other, from the frame A, so that between the window-pane and the opening of
the window on three sides a wall like a Venetian blind formed of alternate gaps
and frames is formed. The intervals between the different parts of the frame,
when the skylight is open, are chosen in such a manuer, according to the breadth
and incline of the sloping frame-parts g and the height of the upright rims, that
the rain, snow etc. after passing by an upper frame strikes each time, the frame
situated below and flows off from here.
The upper frame B is attached to frame A, which holds the skylight by means
of a hinge b and as all the parts CC, C, hang free to the part B, the whole window
can be turned upwards or backwards so that the apparatus does not prevent any
one from climbing through the window on to the roof.
In order to fasten the skylight, when open, any kind of adjustable iron bar may
be used as in ordinary skylights.
Having now particularly described and ascertained the nature of any said
invention and in what manner the same is to be performed, I declare, that what I
claim is:
In skylights that are opened upwards:
1. The arrangement of several roof-shaped frames (C C₁ C₂) hung on to a move-
able skylight frame (B) containing the window-pane, in such a manner, that, on the
window being opened, gaps are formed between the different frames, by means of
which the garret may be aired also in rainy or snowy weather, without the rain or
snow being able to enter into the garret.

page_text: 2. The attachment of the skylight-frame B by means of the hinges b to the
frame A of the skylight in such a manner, that the whole contrivance can be
turned back on the hinges b, so that it is possible to get on to the roof by the
-skylight.
Dated this 24th.day of May 1895.
