Year: 1859

page_text: LETTERS PATENT to John Scott, of Sunderland, in the County of
Durham, Anchorsmith, for the Invention of "AN IMPROVEMENT
ANCHORS."
Sealed the 11th May 1860, and dated the 12th November 1859.
PROVISIONAL SPECIFICATION left by the said John Scott at the Office.
of the Commissioners of Patents, with his Petition, on the 12th
November 1859.
I, JOHN SCOTT, of Sunderland, in the County of Durbam, Anchorsmith,
do hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
ANCHORS," to be as follows:-
My Invention relates to those anchors in which the arms carrying the
flukes move about a pin or bolt at the end of the shank, and consists in fitting"
a toggle to each arm in lieu of the "horns," which are now welded to them.
I prefer to form the toggle of three pieces of metal, two side plates formed'
with a lug and an aperture therein for the reception of a pin or bolt, and a
filling up piece or block which is curved at bottom and held by pins or rivets
between the two side plates. A bolt is passed through the side plates and
through a hole formed in the arm in order to secure the toggle thereon. The

page_text: toggle moves upon the bolt within limits determined by the curve on the
bottom of the filling up block. The toggle may also be made in one piece
with lugs projecting downwards and embracing the arm.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Scott in the Great Seal Patent Office on the
12th May 1860.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SCOTT, of Sunderland, in the County of Durham, Anchorsmith, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of November, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Scott, Her special licence that I, the said John Scott, my
executors, administrators, and assigns, or such others as I, the said John Scott,
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 terni
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 "AN IMPROVEMENT IN ANCHORS," upon the
condition (amongst others) that I, the said John Scott, my executors or
administrators, 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 John Scott, 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say :-
My Invention relates to anchors generally, but principally to those anchors
in which the arms carrying the flukes move about a pin or bolt at the end of

page_text: the shank, and consists in fitting a toggle to each arm in lieu of the "horns,"
which are now welded to them. I prefer to form the toggle of three pieces
of metal, two side plates formed with a lug and an aperture therein for the
reception of a pin or bolt, and a filling up piece or block which is curved at
bottom and held by pins or rivets between the two side plates. A bolt is
passed through the side plates and through a hole formed in the arm in order
to secure the toggle thereon. The toggle moves upon the bolt within limits
determined by the curve on the bottom of the filling up block; the toggle
may also be made in one or two pieces with lugs projecting downwards and
embracing the arm. I also make the toggle a fixture by moving the bolt
from the centre to a little on one side of the centre of the lugs.
Figure 1 of the accompanying Drawings is a side elevation; and Figure 2
a front or back elevation of an anchor with my improvement applied to it.
a is the shank of the anchor; b, b, are the arms carrying the flukes c, c, which
move about a pin or holt d, at the end of the shank; e, e, are toggles free to
move a certain distance about pins f, f. Figure 3 is an end view; Figure 4
a side view; and Figure 5 a section through the line x, y, of Figure 3 of one
of these toggles; g, g, are two side plates formed with holes for the reception
of pins or bolts i, i, which pass through the arms b, b; k is a filling up piece
or block which is curved at bottom and is held between the two side plates g, g,
by pins 1, 1, passing through the block and side plates. The curved portion of
the block k is distinctly shown at Figure 5, and it is this curve which
determines the amount of play the toggle has on the arm. Figure 6 is an
end view; Figure 7 a side view; and Figure 8 a section through the line v, w,
of Figure 6 of a toggle made in one piece. m, m, are lugs projecting down-
wards which embrace the arm of the anchor. The motion of the toggle is
determined in this arrangement as well as in the other by the curved portion,
or what in the first named toggle was called the filling up piece or block, and
marked, but in the last toggle is formed in a piece with it.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my improvement
in anchors,
First, the fitting of a toggle to each arm of an anchor in lieu of horns as
herein-before described and illustrated in the accompanying Drawings.
Second, the construction of toggles for anchors in three parts as herein-
before described and illustrated at Figures 3, 4, and 5, of the accompanying
Drawings.
And, third, the construction of toggles for anchors in one or two pieces

page_text: as herein-before described and illustrated at Figures 6, 7, and 8 of the
accompanying Drawings.
In witness whereof, I, the said John Scott, have hereunto set my hand
and seal, this Tenth day of May, One thousand eight hundred and
sixty.
Signed, sealed, and delivered by the above
John Scott (being first duly stamped)
in the presence of
W. MOORE, Solicitor,
Sunderland.
JOHN SCOTT. (L.S.)
