I, EDMUND HORBACZEWSKI, of 7 Getreidemarkt, Vienna, Austria, Captain, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an extensible roof awning or the like for covering open
spaces, to serve as a protection from the weather and for other purposes, the said roof
when not in use being folded within a suitable casing.
The said roof comprises a number of sections, each of which is either in the form of
a plate or of a lattice girder covered with glass or the like, and made of any suitable
material.
The several roof sections are each bent at their upper and lower edges so as to be
overlapped by the section above and to overlap the section below and are arranged
upon iron rods which serve as braces and yet permit their free movement when the
sections are slid together and asunder, each roof section being arranged to slide upon
the rod of the section above it.
The said rods serve at the same time as guides and for the purpose of facilitating
the motion run between pairs of rollers arranged at two, three or more points according
to the length of the roof.
The roof sections thus connected are supported by beams or rafters which can be
either rigid iron bars or wire ropes.
The several roof sections have blocks rivetted to them for guiding them on the
rafters, rollers being placed in the said blocks. Moreover on every roof section is
arranged a roller that runs upon the roof section beneath it. The said blocks must be
of varying height according to the distance of the respective roof section from the
rafter, in order that the several sections shall be parallel to one another and can be
displaced without rubbing against one another.
The roof sections are extended and withdrawn by means of ropes, chains or the
like which are arranged so as to run on the underside of the roof between rollers
whose axes are supported in brackets of varying height, in order that the traction
ropes shall pass parallely to the roof, the said brackets being rivetted to the roof
sections.
One end of each rope or chain is secured to the underside of the lowermost roof

page_text: section the other end passes around a pulley which is provided on the rear side of
the box within which the sections are located when not in use or on the wall, and,
is conducted around another pulley when it passes downwards within reach of an
operator. Suspended from the united ends of the ropes or chains is a counter weight
by which the roof is balanced, so that a slight strain upon the ropes causes the roof
sections to slide together.
In the said box are fixed blocks forming prolongations of the roof rafters upon
which the rollers running on the rafters and the lower friction rollers of the
traction ropes, rest, so that the roof sections retain their normal slope when slid
together.
On the uppermost roof section is arranged an iron rod from which the roof is
suspended in the distended state and which is provided at its ends with rollers running
in grooves and moving as far as the front wall of the said box, against which wall the
rod then bears and is thus held.
On the lowermost roof section is likewise provided another iron rod to enable a
uniform descent, this rod is connected in a suitable manner by bolts and hooks with
the rafters.
By means of these two rods the roof is stretched and fixed. To the rod on the
lower section can be rivetted a perpendicular sheet metal plate which can serve as a
sign and for the formation of the gutter, and which when the roof is slid together,
closes the aperture in the said box.
If wire rope rafters or supports are used instead of the rigid iron bars the roof
sections are connected with and guided by them as with the traction ropes. The
wire ropes are first stretched tight, and the roof sections are then slid asunder and
fixed.
For preventing the roof from being lifted off by the wind a roller can be provided
below each rafter or it can be prevented by pins or by means of blocks embraced by
the rafters. The tightly stretched traction ropes guided between pulleys will however
generally be sufficient to prevent the roof being lifted off.

page_text: I, EDMUND HORBACZEWSKI, of 7 Getreidemarkt, Vienna, Austria, Captain, 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 an extensible roof, awning or the like for covering open
spaces to serve as a protection from the weather and for other purposes the said roof
when not in use being folded within a suitable casing.
The said roof comprises a number of sections each of which is either in the form of
a plate or of a lattice girder covered with glass or the like, and made of any suitable
material.
In the accompanying drawings
Figure 1 is a transverse section of such a roof slid together in a suitable
wooden box.
Figure 2 is a perspective view of the said roof distended, one part being broken
away.
Figure 3 is a transverse section drawn to an enlarged scale of the roof as slid
together in the box.
Figure 4 is a side elevation of a detail of Figure 3.
Figures 5 to 8 show details of construction.
Figures 9 to 12 show arrangements to provide against the roof being lifted off by
the wind.
Figure 13 is a plan of the distended roof to a reduced scale.
The several roof sections a a¹ are each bent at their upper and lower edges and are
arranged upon iron rods bb' which serve as braces and yet permit their free move-
ment when the sections are slid together and asunder; as shown in Figure 7 the
lowermost roof section a is arranged to slide upon the rod b above it, this rod is
rivetted to the part a' which again is arranged upon the rod 6¹ and so on.
The said rods b serve at the same time as guides and for the purpose of facilitating
the motion, between pairs of rollers rr Figures 7 and 8 arranged at two, three or
more points according to the length of the roof.
The roof sections thus connected with each other are supported by beams or
rafters which can be either rigid iron bars & Figures 1, 2, 5, and 6 or wire ropes
Figure 8.
The several roof sections have blocks f riveted to them for guiding them on the
rafters, rollers s being placed in the said blocks, which rollers run upon the iron
rods c.
Moreover on every roof section is arranged in blocks g, a roller w that
runs upon the roof section beneath it. The blocks must be of varying height
according to the distance of the respective roof section from the rafter, in order that
the several sections shall be parallel to one another and can be displaced without
rubbing against one another.
The roof sections are extended and withdrawn by means of ropes h chains or the
like Figures 3 and 8 which are arranged so as to run on the underside of the roof
between rollers t t¹ whose axes are supported in brackets m of varying height, in
order that the traction ropes shall pass parallel to the roof the said brackets being
riveted to the roof sections.
One end of each rope or chain his secured to the underside of the lowermost roof
section in a ring o the other end passes around a pulley p which is provided on the

page_text: rear side of the box within which the sections are located when not in use or on the
wall, and is conducted around another pulley g when it passes downwards. Suspended
from the united ends of the ropes or chains is a counter weight G by which the
roof is balanced, so that a slight strain upon the ropes causes the roof sections to slide
together.
In the said box k are fixed blocks n forming prolongations of the roof rafters 6, and
traction ropes h upon which the rollers s running on the rafters and the lower friction
rollers t of the traction ropes rest, so that the roof sections retain their normal slope
when slid together.
On the uppermost roof section is arranged an iron rod E from which the roof is
suspended in the distended state and which is provided at its ends with rollers W,
running in grooves 7 and moving as far as the front wall of the said box, against which
wall the rod then bears and is thus held.
On the lowermost roof section is likowise provided another iron rod E¹ to enable a
uniform descent; this rod is connected in a suitable manner by bolts and hooks with
the rafters.
By means of these two rods E and E¹ the roof is stretched and fixed. To the
rod E on the lower section can be riveted a perpendicular figured sheet metal
plate B which can serve as a sign and for the formation of the gutter, and which when
the roof is slid together, closes the aperture in the said box k.
If wire rope rafters or supports are used instead of the rigid iron bars, the roof
sections are connected with and guided by them as with the traction ropes. The
wire ropes are first stretched tightly, and the roof sections are then slid asunder
and fixed.
For preventing the roof from being lifted off by the wind the arrangements shown
in Figures 9 to 12 are employed.
This can be effected by providing a second roller & below each rafter e Figure 9,
or it may be prevented by pins Figures 5 and 11, or by the peculiar shape of the
roof rafters c Figure 12 which are embraced by the blocks f. The tightly stretched
traction ropes h guided between pulleys will however generally be sufficient to prevent
the roof being lifted off.
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 :-
First. The arrangement of the sliding roof sections a a¹ having the rollers w
which run upon the several roof sections and the rollers s which run upon the roof
rafters c, substantially as described.
Second. The arrangement of the traction ropes which run between pulleys tt',
substantially as described.
Third. The provisions against the lifting off by wind, consisting of devices which
embrace the roof rafters below, substantially as described with reference to Figures 9
to 12 of the drawings.
Fourth. The arrangement for replacing the roof rafters c by wire ropes h, sub-
stantially as described with reference to Figure 8 of the drawings.
Fifth. The arrangement of the guide rods b, Figures 6 and 7.
Sixth. The combination of the traction rope with a counter-weight G as above
described.
