page_text: PROVISIONAL SPECIFICATION,
I, JOHN BUCHANAN, of Gourock, in the County of Renfrew, North Britain,
Gentleman do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF SHIPS " to be as follows:―
This Invention which relates to Improvements in the construction of ships,
consists in providing the hulls thereof, whether sailing ships or steamships, with a
longitudinal vertical bulkhead extending the whole length and depth of the hull.―
By this arrangement, the hull is divided into two complete longitudinal compart-
ments independent of each other, that is to say, if one of such compartments
becomes damaged by collision or otherwise the other of such compartments is not
thereby affected.-The aforesaid longitudinal compartments are further subdivided
by transverse bulkheads.

page_text: I, JOHN BUCHANAN of Gourock, in the County of Renfrew, North Britain,
Gentleman, do hereby declare the nature of the invention for IMPROVEMENTS IN
THE CONSTRUCTION OF SHIPS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The Invention, which relates to Improvements in the construction of ships,
consists in providing the hulls thereof, whether sailing ships or steam-ships, with a
longitudinal vertical bulkhead extending the whole length and depth of the hull.
By this arrangement, the hull is divided into two complete longitudinal compart-
ments independent of each other in such manner that if one of such compartments
becomes damaged by collision or otherwise, the other of such compartments is not
thereby affected. The aforesaid longitudinal compartments are further sub-divided
by transverse bulkheads.
In order that the said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the drawings hereunto annexed..
Figure 1, is a diagrammatic side elevation of the hull of a ship constructed
according to the present Invention.
Figure 2 is a plan of the same and Figure 3 is a transverse section of the same
taken at midships.
In carrying the present Invention into practice, I provide the hulls a, whether
of sailing ships or of steamships, with the longitudinal vertical bulkhead b, whose
position is represented in dotted lines at Figure 2 of the annexed drawings. By
this arrangement the hull a, is divided into two complete longitudinal compart-
ments A and B, independent of each other. By these improvements, if one of the
compartments A and B becomes damaged by collision or otherwise, the other of
the said compartments, is not thereby affected. The longitudinal compartments A
and B are further subdivided by transverse bulkheads c, which may be arranged at
any convenient.intervals along the length of the ship.
.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to, be performed, I declare that what
is claimed is
The construction of the hulls of sailing ships and steamships with a longitudinal
vertical bulkhead all substantially as and for the purposes herein before set forth
with reference to the annexed drawings.
