hereby declare the nature of this invention to be as follows:-
The object of this invention is the supplying of a readier means than has hitherto
been used for raising vessels sunk in a depth of water where it is practicable for
divers to work.
The means to be employed consist of;
1st. The introduction at certain distances of steel or iron ribs or belts running from
her keel or kelson up the sides and athwart the deck of the ship.
2nd. The introduction of lignum vitæ screws with a specially prepared head, so
that the screws may be easily removed by a tool provided for the purpose.
3rd. A steel or iron ring headed screw bolt to take the place of the lignum
vitæ one.
4th. The introduction through the ring bolts of the different screws of a chain or
steel cable to which will be attached the lifting power.

page_text: Improvements in Means for Raising Sunken Vessels.
I, JOHN BROADY, of Rampant Horse Hotel Mytongate, Hull, Licensed Victualler,
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 :-
12
The object of my invention is to provide a readier and more efficient means, than
has been obtainable with the various appliances..hitherto employed, for raising vessels
which have sunk to a depth where it would be practicable for divers to work."
In order that my Invention may be the better understood I have appended the
accompanying sheet of drawings in which Figure 1 represents a side elevational view
of a vessel partly in section illustrative of the application of my invention.
Figure 2 is.a plan of same and Figure 3 is a cross section slowing the disposition
of the belts and eye bolts; Figures 4, 5, and 6 are detailed views to enlarged scale
showing the construction of the belts and eye-bolts.
Figures 7 and 8 are detailed views of an alternative method of building up the
belts and Figure 9 is a detached end view of the plug hereinafter described which I
employ for filling up the holes in the belts when the eye bolts are not in place.
In carrying out my Invention I provide, in addition to the ordinary angle-iron
frames.or ribs forming the skeleton of a vessel, a number of solid,iron or steel belts C
of rectangular, or other suitable form in cross section as shown more. particularly in
Figures 3, 4, 5 and 6, disposed at suitable distances apart, and bent to the conforma-
tion of the part of the vessel to which the belt is to be adapted. Said belts being
constructed with enlargements or bosses A at two or more points. A tapped hole B
formed in the centre of said bosses and through the skin plating of the vessel, allows
of the insertion therein of a screw eye-bolt F, Fig. 6 or plug E Figures 5 8 and 9 as
the case may be.
J
Instead of the solid bar belts built up in the manner above described I may as an
alternative method form the belts of two angle irons J-Figures 7 and 8, said angle
irons being opened out or expanded at two or more points, in which expansions are
inserted and securely bolted double wedge shaped blocks K. A tapped hole B formed
in the centre of said blocks allows of the insertion of a screw eyebolt F Figure 6 or
plug E Figure 9 as the case may be.
The belts above described may extend to and embrace the centre keelson of the
vessel. Or instead of being secured to the centre keelson said belts may extend only
to the bilge keelsons as shown at D Figure 3 to which they would be securely bolted.
The upper ends of the belts are carried above the deck of the vessel and formed with
an eye G Figure 3 into which may be inserted a shackle bolt.
To each enlarged boss of the solid bar belts Figures 3. 4. 5 and 6 or to the inserted
blocks of the built up angle iron belts, Figures 7 and 8, a strong back plate H is
riveted, the said plate extending over the two adjacent frames of the vessel and
securely riveted or bolted thereto.

page_text: When a vessel provided with my improved lifting device is under weigh, the tapped
holes B in the bosses A, or blocks K of the belts would be fitted with screw plugs E
Figures 5, 8 and 9, the flat heads of which preserving a flush surface with the vessel's
plates would not in anyway effect the rate of speed of the vessel. Said screw plugs E
which may be formed of lignum vitæ, brass or other suitable material or metal have
two holes formed therein, in which may be inserted the points or lines of a forked
turnscrew, for screwing or unscrewing said plugs when required.
In the event of a vessel having my improved lifting frames or belts sinking, the
divers remove the screw plugs E and replace them with the eyebolts F above described,
to which latter chains or cables are shackled as shown in dotted lines.
Figures 1 and 2
for attachment to the lifting gear. The chains may be disposed in any convenient
manner either fore and aft, or, so disposed as to encircle the vessel, or both methods
combined may be adopted, by which means the vessel may be raised without risk of
the parting thereof amidships.
The weight of my improved appliances will not add materially to the displacement
of the vessel to which same may be adapted.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
First: In the building of vessels the adaptation to the frames thereof of a number
of lifting frames or belts disposed at certain distances apart and extending from the
keel or keelson up the sides and above the deck of the vessel substantially as and for
the purposes herein described and shown in the accompanying drawings.
Second-In combination with the lifting frames or belts herein described the
employment therewith of screw plugs formed of lignum vitæ, brass, or other material
or metal substantially as herein set forth.
Third In combination with the lifting frames or belts the adaptation thereto and
employment therewith of ring or eyebolts in substitution of the screw plugs referred
to in the preceding claim substantially as and for the purposes herein described and
shown.
Fourth-In combination with lifting frames and ring or eyebolts the employment
of chains or cables substantially as and for the purposes herein set forth.
Dated this 7th day of March 1889.
