I, WILLIAM BRUCE THOMPSON of Dundeo in the County of Forfar North
Britain do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF IRON, STEEL AND COMPOSITE SHIPS" to be as follows:-
This Invention relates to improvements in the construction of iron steel and
composite ships and consists in constructing the frames of such ships of channel
iron or steel in lieu of the ordinary combination of angle frames and reverse frames
whereby the riveting required for their connection is dispensed with and at the
same time a section of iron or steel is provided which is more suitable for allowing
the shell riveting to be performed by the riveting machine.
In the construction of the beams of iron steel and composite ships I also employ
channel iron or steel in lieu of the ordinary combination of bulb plate and two
anglo irons thereby dispensing with the riveting required for their connection and
at the same time providing a more suitable section for deck-beams and one
admitting of a more satisfactory connection to the frames.
In the construction also of the hold and other kelsons of iron, steel and composite
ships I employ channel iron or steel in lieu of the plates, bulb plates and angles
hitherto used for the kelsons thereby dispensing with the riveting required for the
connection of the same; or I may use H, or what is known as the "Zore" section
of iron and steel in lieu of the channel section.
'
My improvements further consist in the employment of edge and edge shell -and
deck plating in combination with my above described improvements so that the
whole of the deck plating or shell plating may be riveted by machinery.

page_text: I, WILLIAM BRUCE THOMPSON, of Dundee, in the County of Forfar, North
Britain do hereby declare the nature of my Invention for IMPROVEMENTS IN THE
CONSTRUCTION OF IRON, STEEL AND COMPOSITE SHIPS and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to improvements in the construction of iron, steel and
composite ships, and consists in constructing the frames of such ships of channel
iron or steel in lieu of the ordinary combination of angle frames and reverse
frames whereby the riveting required for their connection is dispensed with, and
at the same time a section of iron or steel is provided which is more suitable for
allowing the shell riveting to be performed by the riveting machine.
In the construction of the beams of iron, steel and composite ships, I also employ
channel iron or steel in lieu of the ordinary combination of bulb plate and two
angle irons, thereby dispensing with the riveting required for their connection, and
at the same time providing a more suitable section for deck-beans and one
admitting of a more satisfactory connection to the frames.
In the construction also of the hold and other kelsons of iron, steel and composite
ships I employ channel iron or steel in lieu of the plates, bulb plates and angles
hitherto used for the kelsons, thereby dispensing with the riveting required for
the connections of the same; or I may use. H., or what is known as the "Zore"
section of iron and steel in lien of the channel section.
My improvements further consist in the employment of edge-and-edge shell and
deck plating in combination with any above described improvements, so that the
whole of the deck plating or shell plating may be-riveted by machinery.
In order that my said Invention inay be most fully understood and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed,

page_text: .
In the construction of the hold and other kelsons, of iron, steel and composite
ships, I employ the channel iron or steel c, in lieu of the plates, bulb plates and
angles hitherto used for the kelsons, thereby dispensing with the riveting required
for the connection of the same. I also uso, for such kelsons, iron or steel of
an I section as represented at f, (Figure 4,) or what is known as the "Zore'
section (as represented at d, Figure 1,) of iron or steal, in lieu of the forms
hitherto used thereby dispensing with much riveting.
As represented at Figure 1, my improvements further consist in the employment
of edge-and-edge shell plating as shown at d, and edge-and-edge deck plating as
shewn at e, in which there is no novelty of itself oxcepting when used in
combination with my hereinbefore described improvements.
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 :—
First In the construction of iron, steel and composite ships, making the
frames a, of such ships, of channel iron or steel, substantially as hereinbefore set
forth with reference to the annoxed Drawings.
Second-In the construction of iron, steel and composite ships, making the
beams b, of such ships, of channel iron or steel, substantially as hereinbefore set
forth with reference to the annexed Drawings.
21
Third In the construction of iron, steel and composite ships, making the
kelsons of such ships of channel iron or steel, or of iron or steal of I or "Zore
sections substantially as hereinbefore set forth with referonco to the annexed
Drawings.
Fourth In the construction of iron, and steel ships, the edge-and-edge shell
plating d, and edge-and-edge deck plating e, in combination with the improve-
inents claimed by the preceding claiming clauses, all substantially as hereinbefore
set forth with reference to the annoxed Drawings.
