page_text: I, Louis QUOILIN, Elisabethring, 56, Budapest, Hungary, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention consists in a new system of sheet roofing which can be put on
easily, quickly, and with security without any folding or soldering, and it per-
mmits the expansion and contraction of the sheets in every direction to allow for
changes of temperature, and prevents the infiltration of water.
In order that my invention may be fully understood, I will now refer to the
accompanying drawings, in which:
-
Figure 1 is an elevation of the covering of a roof border.
Figure 2 a section of same.
Figure 3 shews the arrangement of a roof corner.
Figure 4 shews its section.
Figure 5 shews the section of the formation of a roof ridge.
Figure 6 shews a covering sheet.
Figure 7 shews a shooting over-sheet in three different views.
Figure 8 shews a sheet to be used for covering a roof border.
Figure 9 shews a perforated plate for fastening the different sheets.
For covering generally two kinds of sheets (a) and (b) are used. These sheets
have recurved borders (c, e, d, f) respectively (g, h, i, k) are of a trapeziform shape,
and complete one another. In each case a positive or covering and a negative
or shooting-over sheet are alternatively employed. The positive sheet (a) is
placed in such a manner that the longer edge of the trapeze be directed towards
the lower border of the roof (gutter) and that this sheet may catch into the two
sheets (b) and (1) being beneath it, by means of the recurved borders (c) and (d).
The negative sheets (b), the shorter borders of which are turned towards the
lower edgings of the roof, shoot over the positive sheets (a) by means of which
the water tends to flow down at the shooting over of the most exposed point,
towards the sheet beneath them with twice as great a fall.
The positive as well as the negative covering sheets are fixed to the roof con-
struction by means of a perforated plate (p) by the help of screws or rivets (nails)
or in any other convenient manner. For this end it is best to use so called screw
bolts, the approximate upper third part of the length of which is provided with
threads. These screw bolts are first driven in and then screwed in.
It will be seen in Fig. 1 that each positive covering sheet (a) covers and is
put in 3 sheets (b, a¹, b) but the latter being likewise fixed to the construction
of the roof the sheet (a) is therefore fixed also at the bottom edging in this way
it is made to be very resistable especially against storm.
The different sheets are provided with bulgings m by means of which they
are stiffened considerably.
This roofing has also the great advantage that its different sheets can expand
or contract freely in any direction when the temperature changes and that the

conductor of heat resist against heat as well as against cold.

I, LOUIS QUOILIN, Elisabethring, 56, Budapest, Hungary, Architect, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention consists in a new system of sheet roofing which can be put on
easily, quickly, and with security without any folding or soldering, and it per-
mits the expansion and contraction of the sheets in every direction to allow for
changes of temperature and prevents the infiltration of water.
In order that my invention may be fully understood, I will now refer to the
drawings, filed with my Provisional Application in which ;-
Figure 1, is an elevation of the covering of a roof border.
Figure 2. a section of same.
Figure 3 shews the arrangement of a roof corner.
Figure 4 shews its section.
Figure 5. shews the section of the formation of a roof ridge.
Figure 6 shews a covering sheet.
Figure 7 shews a shooting over-sheet in three different views.
Figure 8 shews a sheet to be used for covering a roof border.
Figure 9 shews a perforated plate for fastening the different sheets.
For covering generally two kinds of sheets a and b are used. These sheets
have recurved borders c, e, d & f, respectively. g, h, i, k are of a trapeziform
shape and complete one another. In each case a positive or covering and a
negative or shooting-over sheet are alternatively employed. The positive sheet a
is placed in such a manner that the longer edge of the trapeze be directed towards
the lower border of the roof (gutter) and that this sheet may catch into the two
sheets 6 and b¹ being beneath it by means of the recurved borders c and d. The
negative sheets 6, the shorter borders of which are turned towards the lower
edgings of the roof, shoot over the positive sheets a by means of which the water
tends to flow down at the shooting over of the most exposed point towards the
sheet beneath them with twice as great a fall.
The positive as well as the negative covering sheets are fixed to the roof con-
struction by means of a perforated plate p by the help of screws or rivets (nails)
or in any other convenient manner. For this end it is best to use so-called screw
bolts, the approximate upper third part of the length of which is provided with
threads. These screw bolts are first driven in and then screwed in.
It will be seen in Figure 1 that each positive covering sheet a covers and is
put in three sheets b, a¹, b¹ but the latter being likewise fixed to the construction
of the roof the sheet a is therefore fixed also at the bottom edging in this way
it is made to be very resistable especially against storm.
The different sheets are provided with bulgings by means of which they
are stiffened considerably.
This roofing has also the great advantage that its different sheets can expand
or contract freely in any direction when the temperature changes and that the

page_text: stratum of air between the boarding of the roof and the sheet cover, being a bad
conductor of heat resist against heat as well as against cold.
Having now particularly 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;-
-
1. The new system of sheet roofing substantially as described and illustrated
herein, consisting of the alternate arrangement of a positive or covering sheet
and a negative or shooting over sheet in one row, which sheets being trapeziform
are provided with recurved borders and joined together by setting each of them
in an opposite direction so that they complete themselves reciprocally. Besides
this, the sheets being provided with bulgings in order to stiffen them better,
are fixed to the construction of the roof with perforated plates by means of nail-
ing or screwing, or in any other convenient manner.
