IMPROVEMENTS IN THE MANUFACTURE OF ANCHORS
Year: 1852

page_text: LETTERS PATENT to Caleb Bloomer, of Westbromwich, in the
County of Stafford, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF ANCHORS."
Sealed the 29th January 1858, and dated the 12th November 1852.
PROVISIONAL SPECIFICATION left by the said Caleb Bloomer at
the Office of the Commissioners of Patents, with his Petition, on
the 12th November 1852.
I, CALEB BLOOMER, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF ANCHORS" to be as
follows:-
My improvements consist in manufacturing anchors in a manner
requiring fewer weldings than by the ordinary modes. The shank, pass-
ing through the centre of the arm, as shewn at (A), works on a rivet
going through both parts of the arm. I also make the toggle and
palm in one piece, as shewn at (B, B). The piece of metal forming the
palm having been wrought to the proper form, is passed between the
two parts of the arm, and bent up to form the toggle; a rivet is then
inserted through both parts of the arm, behind the toggle and palm
at (C). This form of toggle enables the anchor to be much more

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CALEB BLOOMER, of Westbromwich, in the County of Stafford, "Manu-
facturer, 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-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Caleb Bloomer, Her special licence that I, the
said Caleb Bloomer, my executors, administrators, and assigns, or such
others as I, the said Caleb Bloomer, 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 THE MANUFACTURE
OF ANCHORS," upon the condition, amongst others, that I, the said Caleb
Bloomer, 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 within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Caleb Bloomer, 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, reference being had to the drawings hereunto
annexed, and to the letters and figures marked thereon (that is
to say):

page_text: My Invention consists in constructing and combining certain parts
f anchors, in such manner that fewer weldings are necessary, and
reater security, strength, and economy obtained.
DESCRIPTION OF THE DRAWINGS.
Figure 1, is an inner view of the flukes or arms; and the palms, and
also shews the rivets at the back of the horn and palm.
2, represents the piece of which the palm and horn, or toggle,
of the anchor is formed; it is shewn, flat, as, it would
"
"
"
appear before being bent up or attached to the fluke of
the anchor.
.
8, shews one of the plates of which the arms or flukes are
formed before being bent into form.
4, a view of the anchor complete.
I now proceed to describe the mode of manufacture:-The arms or
nkes of the anchor are made in two separate pieces or plates of iron,
of the form shewn at (Figure 3), drawn under the hammer of the
ntire size required, and are afterwards bent to the requisite sweep by
neans of hydraulic or other suitable pressure. It will be seen, on
eference to (Figure 1), that there is a space between the plates E, E,
o receive the shank, which is also drawn in manner well known in the
rade. A hole is drilled at the lower part of the shank, which is con-
ected to the flukes by a bolt at the crown, as seen at (A,) Figure 4).
The palm and horn are made in one solid piece (see Figure 2), and
re afterwards bent into the required form; this piece is then placed
between the two plates E, which form the flukes, and which clip the
orn and palm at the necking (A, Figure 2), and the rivets (F,
Figure 1,) are inserted, connecting the two parts of the arms; the
horn and palm are thus secured in their position. The points of the
alm, and the two points of the arm or fluke, are then welded together
t one heat (see D, Figure 4). The stock is passed through the
hank, and secured by a bolt pin, and a ring is also attached by a pin
o the end of the shank; the whole anchor is then complete, and
eady for use.

page_text: Having thus described the nature of my said improvements, and the
manner in which the same are to be performed; I wish it to be clearly
understood that what I claim as my Invention is, the mode of con-
structing and combining the parts marked A, a, B, C, D, E, and F, as
shewn and described, or any mere modification thereof in which the
flukes are made of two plates or bars of iron welded together at the
ends, with the shank passing between them, and the palm and horn
are made out of one piece, as described.
In witness whereof, I, the said Caleb Bloomer, have hereunto
set my hand and seal, this Seventh day of May, in the
of our Lord One thousand eight hundred and fifty-three.
