PROVISIONAL SPECIFICATION.
Improved and New Methods of Construction to be used in the
Building of Ships.
I, DAVID HOLLAND, of 38 Hamilton Street, Cardiff, Marine Surveyor and.
Naval Architect, do hereby declare the nature of this invention to be as
follows:-
A longitudinal system of framing the hulls of iron and steel vessels, whereby-
First. The longitudinal strength of the hull is increased.
Second. The inside seams of the shell plating may be caulked.
Third. The structural portions of the hull may as far as possible be made
interchangeable.
Fourth. The facility for carrying out repairs is increased.
Fifth. The first cost is reduced.
GENERAL DESCRIPTION OF THE METHOD OF FRAMING CONSTITUTING THE
INVENTION.
The frames may be made of angle, bulb angle, Z, channel, bulb, T, T bulb, or
other suitable section or combination of two or more sections, running parallel
(or nearly so) with the centre line sheer of the hull, and where the inside
and
or
seams and edges are required to be caulked, the frames are built with sufficient.
space between them and the caulking edge to allow of caulking to be done.
The frames may have reversed bars, floor plates, keelson plates, stringer plates,
or other structural portions of the hull fastened or riveted to them, and at suitable
intervals, the longitudinal structure may be stiffened and strengthened transversely
with web frames, bracket plates, knee plates, with the necessary attachments.
Dated this 4th day of June 1892.

COMPLETE SPECIFICATION.
Improved and New Methods of Construction to be used in the
Building of Ships.
I, DAVID HOLLAND of 38 Hamilton Street, Cardiff, Marine Surveyor &
Naval Architect 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 :—
A longitudinal system of framing the hulls of iron and steel vessels in which
the frames may be made of angle, bulb angle, Z, channel, bulb, tee, tee bulb, or
other suitable section or combination of two or more sections, running parallel (or
nearly so) with the centre line and sheer of the hull, and where the inside
or
seams and edges are required to be caulked, the frames are built and placed with
sufficient space between them and the caulking edge to allow of caulking to be
done.
The frames may have reversed bars, floor plates, keelsons, stringers, or other
structural portions of the hull fastened or riveted to them, and at suitable intervals
the longitudinal structure may be stiffened and strengthened transversely with web
frames, brackets, knees, gussets, with the necessary attachments.

page_text: It is also intended, as far as the design and form of the vessel may permit, to
duplicate the plates, frames and other portions of the structure of the hull by
making as many as possible from the same template or mould, which this herein
described new method of shipbuilding is specially adapted for.
In the accompanying drawing, A. A. are inside longitudinal edges of the shell 5
plating intended to be caulked, for which purpose the longitudinal frames C. C.
are placed and spaced at sufficient and suitable distance from the caulking edges:
B B are the outside longitudinal edges of the shell plating which may be caulked
as usual.
Having now particularly described and ascertained the nature of my said inven- 1
tion and in what manner the same is to be performed, I declare that what I
claim is,-
First. The inside serme of the shell plating may be coulked
