PROVISIONAL SPECIFICATION.
An Improved Internal Covering or Lining for Corrugated Metal
Roofing.
1
I, WILHELM LORENZ of No. 44 Westendstrasse of Karlsruhe in the grand Duchy
of Baden, German Empire, Engineer and Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to an improved internal covering or lining for roofs made
of corrugated sheet metal, which I will describe with reference to the accompanying
drawing in which Fig. 1 shews a cross section of a roof, Fig. 2 a part longitudinal.:
section, and Figs. 3 and 4 enlarged details.
Into the corrugations are fitted at suitable distances apart, such as about 5 feet,
wood bearers' b which consist of separate lengths butting against each other and
fixed together by means of wood side cheeks cc, while to the under side is
nailed an iron band e, thus forming a continuous arched beam, which, being supported"
at each end on a shoe or wall plate, will carry itself without any attachment to the
corrugated metal or its trussing, and is sufficiently strong to carry an internal covering
or lining. This consists of boards d which are introduced into the grooves formed
between the cheeks c c and the iron band e, and, being pushed close together, form a
complete lining to the roof. Any fixing of these boards is unnecessary.
improving the appearance, the exposed under surface may be coated with suitable
light colored paint, by preference such as is fireproof. The space, betweeen the
lining and the corrugated metal can be filled in with suitable material that is a bad
conductor of heat, such as slag-wool &c.
For
This construction of covering for corrugated metal roofs has the advantage that it
can be constructed entirely of waste pieces of wood, and that it requires no other
fastenings or connections than those stated. It forms an internal roofing carrying
itself quite independently of the metal roof, and serving as protection against the
dripping of moisture and changes of temperature.

COMPLETE SPECIFICATION.
An Improved Internal Covering or Lining for Corrugated Metal
Roofing.
I, WILHELM LORENZ of No. 44 Westend-Strasse of Karlsruhe in the Grand
Duchy of Baden, German Empire, Engineer and Manufacturer, 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 improved internal covering or lining for roofs made of
corrugated sheet metal which I will describe with reference to the drawing accom-
panying my. Provisional Specification in which Fig. 1 shews a cross section
of a roof Fig. 2 a part longitudinal section, and Figs. 4 and 5 enlarged details.
Into the corrugations. are fitted at suitable distances apart, such as about 5 feet,
wood bearers b, which consist of separate lengths butting against each other and
fixed together by means of wood side cheeks c c, while to the under side is nailed an
iron band e thus forming a continuous arched beam, which, being supported at each
end on a shoe or wall plate, will carry itself without any attachment to the corrugated
metal or its trussing, and is sufficiently strong to carry an internal covering or lining.
This consists of boards d which are introduced into the grooves formed between the

page_text: cheeks cc and the iron band e, and being pushed close together, form a complete
lining to the roof. Any fixing of these boards is unnecessary. For improving the
appearance the exposed under surface may be coated with, suitable light; coloured
paint, by preference such as is fireproof. The space between the lining and the
corrugated metal can be filled in with suitable material that is a bad conductor of
heat, such as slag.wool &c.
This construction of covering for corrugated metal roofs has the advantage that it
can be constructed entirely, of waste pieces, of wood and that, it requires no other
fastenings or connections than those, stated. It forms an internal roofing carrying
itself quite independently, of the metal roof, and. serving as. protection against the
dripping of moisture and changes of temperature.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
An internal covering or lining for corrugated metal roofing consisting of bearers b,
fitted at certain distances apart into the corrugations, and the separate lengths of
which are secured together by side cheeks c c, and which are strengthened by iron
bands serving to carry lining boards, d, substantially as herein described with reference
to the accompanying drawings.
