PROVISIONAL SPECIFICATION left by the said William. Elbert Dando
at the Office of the Commissioners of Patents, with his Petition, on the
21st December 1858.
I, WILLIAM ELBERT DANDO, of the State of Pennsylvania, in the United.
States of America, at present residing in Manchester, in the County of
Lancaster, Clerk, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR LOWERING BOATS FROM SHIPS OR VESSELS, AND:
ALSO FOR RAISING THE SAME AS REQUIRED," to be as follows:-
This Invention is designed principally for the lowering of boats from ships.
into the water in cases of emergency or otherwise, and to effect such operation.
with promptitude and safety, and at the same time to lift, carry, or lower the
boat at almost any convenient distance away from the ship's side, so as to :
ensure the security of the boat by placing it safely.in the water far beyond the
ship, or even the paddle-boxes and surf of steam vessels. My improvements
are distinctly shewn in the Drawing attached, in which, Fig. 1, A represents a..

to be lowered; Fig. 2 being a side elevation of the same; b, b, upright portion
or standards of crane (in place of "davits "); d, d, braces and arms of crane ;
c, c, eye bolts, attached to vessel's side; i, i, bolt or pivot, running through

crane standards; k, chain or rope, by which the whole crane and boat is
lowered or raised at one and same time; f,f, "self-detaching safety hooks" or
couplings, may be advantageously applied for the purpose of detaching the
boat as required when placed in the water, as shewn by the dotted lines D, in
Figure 1.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Elbert Dando in the Great Seal Patent Office on
the 21st June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ELBERT DANDO, of the State of Pennsylvania, in the United States of America,
at present residing in Manchester, in the County of Lancaster, Clerk, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Elbert Dando, Her special license that I, the said William
Elbert Dando, my executors, administrators, and assigns, or such others
as I, the said William Elbert Dando, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN APPARATUS FOR LOWERING BOATS FROM SHIPS OR
VESSELS, AND ALSO FOR RAISING THE SAME AS REQUIRED," upon the condition,
amongst others, that I, the said William Elbert Dando, by an instrument in
writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office

page_text: within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said William Elbert Dando, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say) :-
:-
This Invention is designed principally for the lowering of boats from ships
into the water in cases of emergency or otherwise, and to effect such operation
with promptitude and safety, and at the same time to lift, carry, or lower the
boat at almost any convenient distance away from the ship's side, so as to
ensure the security of the boat by placing it safely in the water far beyond the
ship, or even the paddle-boxes and surf of steam vessels; the apparatus being
also applicable for raising the boat and returning it to its former position
when required.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings or Diagrams illustrative
of the same, having similar letters of reference marked upon corresponding
parts in the several Figures.
Figure 1, a front elevation of the improved apparatus (as attached to the
ship's side), consisting of a double-acting crane, and shewing the arms and
braces which support the boat turned outwards; Fig. 2 shews the stern of a
ship with a crane on either side; at one side of the ship the boat is shewn
as it would be when lowered in the water; and Fig. 3 shews a side elevation
of the boat suspended, and the double-acting cranes as attached to the vessel's
side. In these several Figures the upright portions or standards of the cranes
are shewn at S, S, (in place of "davits"); a, a, are braces, attached to the
standards; and b, b, are curved arms fitted into the swivels c, and attached at
their extremities to the braces d; c, c, are swivels turned on the uprights S, S;
d, d, braces, supporting the curved arms b, and turning on pivots at the upper
end of the standards S; e, e, are eye bolts, to be attached to the vessel's side,
and in which the standards S, S, turn on the bolts or pivots f, f, thereby
forming a hinge, by means of which arrangement the boat D can be lowered
into the water, as shewn on the left-hand side of Fig. 2, by releasing the
chains g, g, which are attached at one end to the upper extremities of the
standards S, S, the other end being secured to the standards below the swivels c.
h is another chain, fastened to the chains g; and i, i, block or pulley, fastened
to the centre of the chain h, and by which means the cranes are lowered, the
weight being equally supported at the points marked 1, 2, 3, 4. It will be
evident that self-acting or self-detaching safety hooks or couplings may be

page_text: advantageously applied for the purpose of detaching the boat as required when
placed in the water.
Having now described the nature of my said Invention, and the manner in
which the same may be performed; I would remark, in conclusion, that
I claim as of my Invention, application, employment, or use of the improved
apparatus for lowering boats from ships or vessels, and also for raising the
same as required, as exhibited in the several Figures of the Drawings
attached to these Presents, and also fully herein described and set forth.
In witness whereof, I, the said William Elbert Dando, have hereunto set
my hand and seal, this Twentieth day of June, in the year of our Lord
One thousand eight hundred and fifty-nine.
WILLIAM ELBERT DANDO. (L.s.)
