Corrugated Sheeting.
I WILLIAM THOMPSON of Custom House Quay Wexford Engineer do hereby
declare the nature of this invention to be as follows:-
This invention consists in using for the booms & tie beams of gable principals of
iron roofs, or other framing to which corrugated iron or steel sheeting is attached,
☐ section bars of iron or steel, placed in pairs, back to back, and coupled, so as to
leave an almost continuous space or slit between the said bars and through which
space or slit the bolts or rivets for securing corrugated iron or steel sheeting to the

Improved Iron or Steel Framing for the Attachment to same of
Corrugated Sheeting.
I, WILLIAM THOMPSON of Custom House Quay Wexford Engineer do hereby
declare the nature of this invention and in what manner the same is to be
perforined, to be particularly described and ascertained in and by the following
statement :-
This invention consists in using for the booms and tie beams of gable principals
of iron roofs, or, other framing to which corrugated iron or steel sheeting is
attached, U or channel section bars of iron or steel, in pairs, and coupled so as to
leave an almost continuous space or slit between the said bars, & through which
space or slit, the bolts or rivets for securing corrugated iron or steel sheeting to
the said gable principals or other framing may be passed at nearly any point to
suit the pitch of the corrugations of the sheeting.
I make this framing by coupling bais of channel or U section iron or steel in
pairs by means of ordinary bolts or rivets placed at suitable distances and leaving
a space or slit between the said bars wide enough to admit the bolts or rivets by
which the corrugated sheeting is afterwards attached. The width of the space or
slit between the said bars is determined by means of blocks or washers-preferably
of iron or steel-inserted between the said bars.
The bolts or rivets by which the corrugated sheeting is attached to the bars or
framing pass through the aforesaid space or slit between the said bars and are
secured behind over washers or plates in the usual manner. As may be seen by
the accompanying diagrams in which the U or channel section bars are represented
in "section" and marked A A. The bolts for coupling same being marked CB;
and the blocks or washers which determine the width of the space or slit between

page_text: the bars being marked F. The corrugated sheeting and the bolts fixing same to
the coupled bars are marked S & B respectively, and the washer behind the bars
retaining the nut of the bolt B is marked W.
Rivets may be substituted for bolts in all cases but bolts are preferable for
convenience.
The said coupled bars may be either curved or straight according to the nature
of the work into which they enter as framing.
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,
Iron or steel framing to which corrugated iron or steel sheeting is attached, such
framing being composed of coupled bars of channel or U section iron or steel,
having an almost continuous space or slit between the said bars, and through which
space or slit the bolts or rivets for securing the said corrugated sheeting are easily
passed at nearly any point to suit the pitch of the corrugations of the sheeting so
affixed.
Dated this 11th day of December 1894.
