IMPROVEMENTS IN ROOF WINDOWS KNOWN AS “DORMER

WINDOWS
My invention relates to improvements in the construction of what are known as
"dormer" windows,-comprising the parts usually constructed respectively of
wood, slates, lead, plaster &c-and consists in making such parts of cast metal.
These parts are the front, sides (or "spandrils") top or roof and flange all round,
to rest upon the main roof, also sashes to the front, sides or top, as may be
required, and all these parts I propose to construct in one metal casting, but
in certain cases, to meet practical difficultios as to size of window or special
architectural requirements, I may make the window in more than one piece but,
in any case I dispense with the different materials enumerated, substituting instead
cast metal.
This mode of construction is applicable to a form of roof window which may
be called an inverted or sunk "dormer," flush with the angle of roof without
projection outside; which form has some advantages and readily adapts itself to
the mode of construction which I propose.

My invention relates to improvements in the construction of what are known as
"dormer" windows comprising the parts usually constructed respectively of wood,
slates, lead, plaster &c, and consists in making such parts of cast metal. These
parts are the front, sides (or "spandrils") top or roof and flange all round, to rest
upon the main roof, also sashes to the front, sides or top as may be required, and
all these parts I propose to construct in one metal casting, but in certain cases, to
meet practical difficulties as to size of window or special architectural requirements
I may make the window in more than one piece but in any case I dispense with
the different materials enumerated, substituting instead cast metal, and in any case
I do without a joint at the junction of the vertical front and sides with the flange
resting on the inain roof.
I also propose to make Dormer Windows as before described but with the front
formed to a Curved line in order to suit roofs of varying slopes and to avoid
having to make a separate casting for each different slope or pitch. These are
either flat on the top or, where it is desirable to save length, the top is hollowed or
sunk across.
"
I also propose to make Dormer windows in either of the previously described
forms but either partly or entirely fitted with “ louvres or perforated surfaces
for ventilation.
When the flange resting upon the main roof is made a separate casting I raise
upon it a portion of the sides and front to form a seat for the superstructure and
so as to avoid a joint at the junction or angle of the vertical surfaces with the
flange.
I also propose to ornament the Dormer windows before described by casting
upon them mouldings, brackets, enrichments, finials or other forms of ornamentation,
or by attaching such thereto by screws or otherwise.
This mode of construction is applicable to a form of roof window which may be
called an inverted or Sunk Dormer flush with the slope or angle of the roof and
without projection outside which form has some advantages and readily adapts
itself to the mode of construction I propose.
I propose to fit the "Dormer" windows of whatever shape with casements or
doors to the front, either sliding or hinged, also to make the top to open as a
skylight when required.

page_text: Figures 1, 2 and 3 shew front and side clevations and section of a dormer
window comprising the various parts in one casting according to my invention with
glazed casement or sash in front and glazed sides.
Figure 4 shews a perspective view of the same.
Figures 5 and 6, shew front and side elevations of a "dormer " window with
curved front applicable to varying slopes of roofs and with the top hollowed out
or sunk to save length of sloping flange.
Figures 7 and 8 show front and side elevations of a "dormer" window same as
Figures 5 and 6 but with flat glazed top.
Figures 9 and 10 shew front and side elevations of a "dormer" window similar
to Figures 5 and 6 but of slightly different shape to gain height at the sides.
Figures 11 and 12 shew front and side elevations of a "dormer" window similar
to Figures 5 and 6 but the front fitted with "louvres," or which may be perforations
for ventilation, and sides glazed.
Figures 13 and 14 shew front and side elevations of a "dormer" window similar
to last but with flat glazed top.
Figure 15 shews a perspective view of flanged plate to rest upon main roof
forming a separate casting with provision for receiving the superstructure at A A A
to be secured thereto, and without any joint at B B, B.
Figures 16, 17 and 18 shew front and side elevations and section of an inverted
or sunk "dormer" window flush with plane of main roof.
Figure 19 shows perspective view of same.
Figures 20, 21 and 22 shew some modes of ornamenting "dormer" windows
constructed according to my invention.
Having now fully described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
First. The construction of roof windows usually known as "Dormer" windows
of cast metal consisting of one casting or of two or more separate castings fitted
together and united by bolts screws or other means, and glazed or partly glazed or
fitted with ventilating appliances substantially as described and illustrated by
Figures 1, 2, 3, 4 of accompanying drawings.
Second. In roof windows usually known as "Dormer" windows consisting of
more than one casting, the construction of the flanged plate resting upon main
roof in the manner substantially as described and illustrated by Figure 15 with
the objects specified.
Third. In roof windows usually known as "Dormer" windows, constructed of
cast metal as described in Claim 1 the formation of the front of a curved shape so
as to adapt it to various slopes or angles of roofs and with a curved or straight
top substantially as described and illustrated by Figures 5, 6, 7, 8, 9, 10, 11, 12, 13
and 14, of accompanying drawings.
Fourth. The construction of roof windows flush with the line of roof, which
may be termed inverted or sunk "Dormer" windows, of cast metal consisting of
one casting or of two or more separate castings fitted together and united by bolts
screws or other means and glazed or partly glazed or fitted with ventilating
appliances substantially as described and illustrated by Figures 16, 17, 18 and 19.
