COMPLETE SPECIFICATION.
Improved Means for Raising Sunken Vessels.
1, REGINALD HADDAN of the firm of Herbert & Co. Registered Patent Agents
of 18 Buckingham Street Strand W.C. London Civil Engincer do hereby declare
the nature of this invention a communication to me from abroad by Ignacio
Paradell y Fané, Ignacio Paradell y Maten, and Enrique Paradell y Mateu, all of
Kue de las Cortes 185, Barcelona, Spain, Hydraulic Engineers and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :--
This invention consists in improved means for raising sunken vessels, and consists
broadly in a hollow vessel of the general form of a ship and of suitable size which
may be towed to the place where the sunken vessel to be raised lies and there
filled with water and sunk and attached to the sunken vessel as hereinafter
described, so that when the water is pumped out by a pump on board the steam
ship or tug which has towed the vessel to its position, the special vessel rises.
again to the surface and so raises the sunken ship which may be towed thus to a
shallower place, dry dock or the like.
Reference being made to the annexed drawings-
Fig. illustrates the sunken ship and raising vessel attached thereto.
Fig. 2 represents in end view the raising vessel and steamer or tug which is
used to tow the raising vessel to its position.
A represents the sunken ship-B the special hollow vessel. The latter is made
air and water tight at all points and is fitted with the two pipes cc the latter of
which extends to near the bottom of the vessel B while the former extends
from the deck only. On the vessel B are the two ring bolts CC, and four hand
winches DD, on which are wound strong chains E E ending in hooks ee. The
steam tug G is fitted with stout ring bolts H or with equivalent stanchions.
The place of the sunken vessel being ascertained, the vessel B is towed to the
spot and placed exactly over the sunken ship A. Very stout hawsers KK
passing through the ring bolts C are secured by divers in any suitable way one at
each end of the vessel A.
These hawsers are then drawn as tight as possible and secured to the
stanchions H. Water is then allowed to fill the vessel B in any suitable way until
the latter sinks slowly upon the wreck A, the rings CC moving on the
hawsers K. Divers then fasten the chains E suitably to the vessel A and by
winding on the winches D get the vessel B as low and close to the hull of the
wreck A as possible.
The water is then pumped out of the vessel B by means of the pipe c' which
leads to a pump on the tug G. Air enters through the pipe c which extends
above the water. The vessel B thus rendered buoyant rises and lifts the
vessel A. The hawsers K may then be again tightened and secured and the
vessel B may be towed to a suitable landing place as aforesaid, alongside
the tug G, the vessel A being suspended close under the vessel B.
The rope M one end of which is attached to the vessel B serves as a measure of
the depth of immersion.
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 :--
The means for raising sunken vessels consisting of the water tight submergible
vessel B substantially as described with guiding hawsers K and attachment chains

page_text: and winches therefor or equivalent means of attachment, adapted to be employed
as herein described.
