Year: 1855

page_text: LETTERS PATENT to Joseph Betteley, of Liverpool, Chain Cable Manu-
facturer, for the Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF
· IRON KNEES FOR SHIP-BUILDING."
PROVISIONAL SPECIFICATION left by the. said Joseph Betteley.at the
Office of the Commissioners of Patents, with his Petition, on the 13th
June 1855.
I, JOSEPH BETTELEY, of Liverpool, Chain Cable Manufacturer, do hereby
declare the nature of the Invention for "AN IMPROVEMENT IN THE MANUFACTURE
OF IRON KNEES FOR SHIP-BUILDING" to be as follows:-
This Invention has for its object an improvement in the manufacture of iron
knees for ship-building. In the Specification of a former Patent I described
the use of angle and trough iron in the manufacture of iron knees for ship-
building, in which cases the iron was rolled parallel. Now, my present
improvement consists of rolling or forming iron for iron knees tapering or
wedge shape, having projecting ribs intermediate of the widths of such iron

page_text: or at the edges thereof, and also forming solid projections at intervals, whereby
the quantity or masses of iron near the bends, and, if desired, at other parts,
are greater in each iron knee for a ship than was the case in my former
patent knees.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Betteley in the Great Seal Patent Office on the
12th December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BETTELEY, of Liverpool, Chain Cable Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Betteley, Her special licence that I, the said Joseph
Betteley, my executors, administrators, and assigns, or such others as I,
the said Joseph Betteley, 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 "AN
IMPROVEMENT IN THE MANUFACTURE OF IRON KNEES FOR SHIP-BUILDING," upon the
condition (amongst others) that I, the said Joseph Betteley, 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 Joseph Betteley, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof (that is to say):-
This Invention has for its object an improvement in the manufacture of iron
knees for ship-building. In the Specification of a former Patent I described
the use of angle and trough iron in the manufacture of iron knees for ship-
building, in which cases the iron was rolled parallel. Now, my present improve-

page_text: ment consists of rolling or forming iron for iron knees tapering or wedge
shape, having projecting ribs intermediate of the widths of such iron or at the
edges thereof;. and also forming solid projections at intervals, whereby the
quantity or masses of iron near the bends, and, if desired, at other parts, are
greater in each iron knee for a ship than was the case in my former patent
knees.
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
The object of the Invention is to roll iron into the forms herein described,
in order to get a greater quantity of metal at the bends or elbows of ships'
knees when simply bending the rolled pieces of iron into knees.
Figure 1 shows a plan, side view, and section of a bar of iron rolled into a
form suitable for making a knee, and it will be seen that the iron tapers from
the middle towards each end, and it is made plain on one side and with ribs
at either edge; in this respect it is similar to what was described in the
Specification of a former Patent granted to me; but in that case the iron was
rolled parallel, whereas in the present the iron is rolled wedge shaped, or
inclined from the middle outwards, the largest substance being at the middle.
Figure 2 shows a plan, a side view, and section of another form in which iron
is rolled trough-like, or with ribs or projections at the edges from end to end,
but with increased quantity of metal at the middle where the bend or knee is
to be produced.
The trough or hollow in this case is also shown of a curved form in place
of flat, as in the other one, but this may be varied. Figure 3 shows a plan,
a side view, and section of another piece of rolled iron with a single rib, and
rolled, inclined, or wedge shaped from the middle outwards, so as to give a
greater quantity of metal where the bend is to take place. Figure 4 shows
a plan, a side view, and section of another piece of rolled iron with an enlarge-
ment or mass at the place where the bend is to take place in order to get
greater strength. Figure 5 shows a side view of another piece of rolled iron,
which is of the same form as that shewn at Figure 4, except that it is rolled
inclined or wedge shape towards one end. By thus rolling the iron into the
desired form for knees, the workman has only to heat the middle portions- and
to bend them into knees, also to perforate the limbs of the knee in each case
with suitable holes. In making such like rolled forms of iron, one of the
rollers employed in each case is formed with a plain surface, corresponding
with the plain surface of the-knee iron shown; and the other roller is prepared
with a groove to produce the other surface of the knee iron shewn, as is well

page_text: understood in manufacturing or rolling iron of irregular forms for other
purposes. I do not confine myself to the precise sections shown, but, what I
claim is, the manufacture or rolling of ships' knee iron such as are herein
shown and described.
In witness whereof, I, the said Joseph Betteley, have hereunto set my
hand and seal, this Tenth day of December, in the year of our
One thousand eight hundred and fifty-five.
our Lord
