Improvements in the Construction of Ships and other Vessels.
I SINOLAIR STUART of Plainfield in the County of Union and State of New Jersey,
United States of America, Engineer, 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 :-
These improvements relates to ships and other vessels constructed of steel or iron,
and the object is to provide for the construction of vessels. having great longitudinal
stiffness and strength. These improvements are not only applicable in the con-
struction of new vessels, but may be used to give additional strength, in a longitudinal
direction, to vessels of ordinary construction already in existence.
Fig, in the accompanying drawings represents a transverse vertical section of
portions of one side wall and decks of n vessel embodying my improvements.
Fig. 2 represents a longitudinal vertical sectional viow taken in the line 2-2 of
Fig. 1, looking from the right of that figure.
AA designate the upper portions of upright frames such as are commonly
employed in the construction of vessels of steel and iron. These may be of channel
or angle form in their transverse section. B B are the transverse deck beams
represented as of channel form, and as connected, as is common, with the frames A A
by bracket plates C. The plating a a is applied outside of the frames A A in
the usual manner.
DD designate stringers of steel or iron, of channel form in transverse section,
which constitute one of the principal features of my invention. These stringers run
lengthwise of the vessel throughout the whole, or any portion of its length, and lie
close to the inside of the frames A A, with the flanges of the channel inwards, and
the webs against the said frames, and they are secured to the frames by angle clips bb,
which are rivetted to the sides of the frames by rivets c c, and to the stringers by
rivets d d. Each stringer may be composed of several sections of as great length as
can be obtained from the rolling mill, the several sections of each being united by
butt straps e e applied within the bosom of the channel, and also on the back thereof,
and securoly rivetted thereto by rivets eel. There may be any number of these
stringers applied below the upper deck, or between the decks, but I prefer to arrange
them in pairs, as shown in the drawings, so close together as only to leave room
between thein for angle straps if, which are each long enough to fill the space
between the fraunes A A. These angle straps are rivetted to the side plating a a by
rivets 9, and are rivetted between the contiguous flanges of the two stringers D D'
constituting the pair, by rivets h h. The stringers thus applied and fastened are so
securely incorporated into the structure of the vessel, as to add greatly to its strength
and stability, and it will be understood that they may not only be applied in the
original construction of a vessel, but may be added to a vessel of ordinary construction
without any alteration of the original structure.
E designates a stringer of channel steel or iron, arranged lengthwise of the vessel,
directly under the transverse deck beams B', with the flanges of the channel down-
wards. Thero may be any number of such stringers E, each running the whole or
any part of the length of the vessel, and arranged with the backs of their channels
close under the deck beams, to which they are fastened by angle clips ii, which are
rivetted to the stringer by rivets jj, aud to the deck beans B, by rivets kk. The
lower flanges of the deck boume B are also rivetted to the stringers E through the
bosom of the latter by rivets 11. The longitudinal stringers E, which contribute

page_text: greatly to the longitudinal stiffness of a vessel, may be applied to a vessel in
construction, or may be added to a vessel already constructed.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with the upright frames and outside plating of a vessel, of
stringers of channel form in transverse section, arranged one above another in pairs
lengthwise of the vessel, inside of, and with their webs against the said frames, and
angle straps interposed and rivetted between contiguous flanges of the two stringers
of a pair, and rivetted to the outside plating, substantially
2. The combination with the upright frames and outside plating of a vessel, of
stringers of channel form in transverse section, arranged one above another in pairs
lengthwise of the vessel, inside of, and with their webs against the said frames, angle
clips rivetted to said frames and stringers, and angle straps interposed and rivetted
between contiguous flanges of the two stringers of a pair, and rivetted to the outside
plating, substantially as herein described.
