object is accomplished by the peculiar construction of the frame consisting of two
parts adapted to slide one over the other, the edges of the roof being embedded
between two flanges. The main object the applicant has in view is to secure a
sufficiently tight closing of the joints to keep out rain, snow and cold.
.
The upper part of the frame has hinged to it a cap or hood formed of a metal
framework in which are fitted panes of glass. By means of a clamp this hood may
be secured in its terminal position when closed, while a rod serves to adjust and fix
it in the open position. The upper edge of the frame portion in conjunction with
the edge of the hood forms a channel for rain-water.
The frame and also a lower frame are of angular section or in other words each
of these parts consists of two pieces set at right angles to each other, the horizontal
pieces forming flanges while the vertical pieces are adapted to move one over the
other. In fitting in a sky-light the lower frame is placed upon the spars or rafters
of the roof and the roofing material is placed over the flange so that it reaches to
the vertical portion. The upper part of the skylight is then placed over the lower
frame so that its flange overlaps the edge of the roof. The two flanges are suitably
connected for example by means of flexible metal strips secured to the flange of the
upper frame and passed through the roofing and through perforations provided in
the flange of the other frame the projecting ends being then turned down. In this
manner thoroughly water and air-tight joints are obtained at the junction of the
frame of the skylight with the roof. To conduct away the rain-water falling
upon the flange of the upper frame a groove is provided which at its lowest part
has its discharge orifice upon the roof.

COMPLETE SPECIFICATION.
Improvements in Sky-lights.
A communication from CARL WERNER, of Pirna on the Elbe, in the Empire of
Germany, Ironmonger.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Member of the Institution of Mechanical Engineers, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :-
This sky-light is distinguishable by the valuable feature that it may be fitted in
place with the utmost facility and yet be closed in a perfectly tight manner. This
object is accomplished by the peculiar construction of the frame consisting of two
parts adapted to slide one over the other, the edges of the roof being embedded

page_text: between two flanges. The main object the applicant has in view is to secure a
sufficiently tight closing of the joints to keep out rain, snow and cold.
In the accompanying drawings,
Figure 1 is a side view,
Figure 2 a top view, and
Figure 3 a section of the improved sky-light.
The upper part of the frame a has hinged to it a cap or hood formed of a
metal framework in which are fitted panes of glass. By means of a clamp b¹ this
hood may be secured in its terminal position when closed, while a rod serves to
adjust and fix it in the open position. The upper edge of the frame portion a in
conjunction with the edge of the hood forms a channel for rain-water!
C
The frame a and also a lower frame care of angular section or in other words
each of these parts consists of two pieces set at right angles to each other, the
horizontal pieces forming flanges while the vertical pieces are adapted to move one
over the other (this is clearly shown in Figure 3). In fitting in a sky-light the
lower frame c is placed upon the spars or rafters of the roof and the roofing material
is placed over the flange so that it reaches to the vertical portion. The upper part
of the sky-light is then placed over the lower frame c so that its flange overlaps
the edge of the roof. The two flanges are suitably connected for example as
shown in the drawing, by means of Hexible metal strips secured to the flange of
the upper frame a and passed through the roofing and through perforations pro-
vided in the flange of the other frame e the projecting ends being then turned down.
It will be seen from the drawing that in this manner thoroughly water and air-tight
joints are obtained at the junction of the frame of the skylight with the roof. To
conduct away the rain-water falling upon the flange of the upper frame a a groove al
is provided which at its lowest part (see Figures 1 and 2 on the left) has its
discharge orifice upon the roof.
Having now particularly described and ascertained the nature of this said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is :-
An improved skylight combining facility of fitting with air and water tightness this
double purpose being fulfilled by passing over a frame such as c of angular section
projecting from the opening in the roof below a second frame such as a of similar
shape which carries the glass panes so that the roof is embedded between the
flanges of the frames, substantially as described and illustrated in the accompanying
drawings.
