Year: 1856

page_text: LETTERS PATENT to Samuel Palmer Gladstone, of Lea Cottage, Orchard
House, Poplar, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF MASTS AND YARDS."
Sealed the 11th April 1856, and dated the 29th January 1856.
PROVISIONAL SPECIFICATION left by the said Samuel Palmer Gladstone
at the Office of the Commissioners of Patents, with his Petition, on the
29th January 1856.
I, SAMUEL PALMER GLADSTONE, of Lea Cottage, Orchard House, Poplar, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF MASTS AND YARDS," to be as follows:-
This Invention has for its object improvements in constructing masts and
yards. For these purposes, the lower part of a mást is made hollow or
tubular, of metal, and such lower part is fixed to the kelson by means of a
flanch and bolts. The hollow or tubular part of the mast rises through the
decks of a vessel in such a manner as to come above all the decks but the
upper deck, and into this tubular or lower part of a mast, a filling piece
or pieces of wood or metal are introduced, on to which the lower end of
the upper part of the mast, which is of wood, steps, and such lower end
is received into and retained in position by the upper portion of the metal
or tubular part of the mast.
In constructing a yard, the middle portion is made of metal, and hollow,.
to receive and have fixed therein two ends of wood.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
PALMER GLADSTONE, of Lea Cottage, Orchard House, Poplar, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Palmer Gladstone, Her special licence that I, the said Samuel Palmer
Gladstone, my executors, administrators, and assigns, or such others as I, the said
Samuel Palmer Gladstone, 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 "IMPROVE-
MENTS IN THE CONSTRUCTION OF MASTS AND YARDS," upon the condition (amongst
others) that I, the said Samuel Palmer Gladstone, my executor's or adminis-
trators, by an instrument in writing under my, or their, or one of their hands
and seals, 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 within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Palmer Gladstone, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in constructing masts and
yards. For these purposes, the lower part of a mast is made hollow or tubular,
of metal, and such lower part is fixed to the kelson by means of a flanch and
bolts. The hollow or tubular part of the mast rises through the decks of a
vessel in such manner as to come above all the decks but the upper deck,
and into this tubular or lower part of a mast, a filling piece or pieces of wood
or metal are introduced, on to which the lower end of the upper part of the
mast, which is of wood, steps; and such lower end is received into and retained
in position by the upper portion of the metal or tubular part of the mast. In

page_text: constructing a yard, the middle portion is made of metal, and hollow, to receive
and have fixed therein two ends of wood.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 show two transverse sections of a ship or vessel having a
mast constructed and applied according to my Invention. a, a, is the tubular
metal part of the mast, which is shewn to step into the kelson, but it may be
fixed thereto by the aid of a flanch and bolts. This tubular metal part of the
mast (which I prefer to be of a square section, as shown at Figure 3), rises up
through the decks, excepting the upper deck, and the lower end of the wood
mast steps on to an internal filling or projection a', as shown, or a filling piece
of wood may be introduced into the tubular metal-part of the mast to receive
and support the lower end of the wood mast b. I would state, that in masts
for steam ships or vessels propelled by a screw or submerged propeller, a passage
may be made through the tubular part of the mast for the passage of the
shaft of the propeller. Figures 4 and 5 show two views of a ship's yard con-
structed according to my Invention; the middle portion c is tubular and of
metal; the two outer portions d, d, pass into either end of the tubular. part
c, and by preference, are scarfed, or overlap, as is shown.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is,
First, the mode herein described of combining the use of metal and wood in
the construction of masts for ships and vessels.
And, secondly, I claim the mode herein described of combining metal and
wood in the construction of yards for ships and vessels.
In witness whereof, I, the said Samuel Palmer Gladstone, have here-
unto set my hand and seal, this Twenty-ninth day of July, in the
year of our Lord One thousand eight hundred and fifty-six.
