IMPROVEMENTS IN THE MANUFAC- TURE OF SEWER AND OTHER PIPES
Year: 1853

page_text: LETTERS PATENT to William Blissett Whitton and George
Samuel Whitton, of 18, Princes Street, Lambeth, in the County
of Surrey, for the Invention of "IMPROVEMENTS IN THE MANUFAC-
TURE OF SEWER AND OTHER PIPES."
Sealed the 13th April 1853, and dated the 15th February 1853.
PROVISIONAL SPECIFICATION left by the said William Blisset
Whitton and George Samuel Whitton at the Office of the
Commissioners of Patents, with their Petition, on the 15th
February 1853.
We, WILLIAM BLISSET WHITTON and GEORGE SAMUEL WHITTON, of
18, Princes Street, Lambeth, in the County of Surrey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF SEWER AND OTHER PIPES" to be as follows: -
This Invention relates to that class of pipes (particularly those
of large diameter) made by forcing clay or plastic materials through
moulding dies or orifices, and consists of making the dies or orifices
in such manner that there are a number of small cores around the
main core, by which small cores longitudinal openings through the
sides of such pipes are produced, in place of the sides of the pipes

page_text: being made solid as heretofore. By which means, though the pipes
be made of greater dimensions than usual, they will dry and-burn
better than when solid at the sides.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said William Blissett Whitton and George
Samuel Whitton in the Great Seal Patent Office on the
15th August 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
WILLIAM BLISSETT WHITTON and GEORGE SAMUEL WHITTON, of
18, Princes Street, Lambeth, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of February, in
the year of our Lord One thousand eight hundred and fifty-three, in
the sixteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said William Blissett Whitton
and George Samuel Whitton, Her special licence that we, the said
William Blissett Whitton and George Samuel Whitton, our exe-
cutors, administrators, and assigns, or such others as we, the
said William Blissett Whitton and George Samuel Whitton, our
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 SEWER AND OTHER
PIPES," upon the condition. (amongst others) that we, the said William
Blissett Whitton and George Samuel Whitton, or one of us, by an
instrument in writing under our hands and seals, or under the
hand and seal of one of us, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same
was to be perforined, and cause the same to be filed in the Great

page_text: Seal Patent Office within six calendar months next and iminediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Samuel Whitton, on
behalf of myself and the said William Blissett Whitton, 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 relates to that class of pipes (particularly those
of large diameter) made by forcing clay or plastic materials through
moulding. dies or orifices, and consists of making the dies or orifices
in such manner that there are a number of small cores around the
main core, by which small cores longitudinal openings through the
sides of such pipes are produced, in place of the sides of the pipes
being made solid as heretofore. By which means, though the pipes
be made of greater dimensions than usual, they will dry and burn
better than when solid at the sides.
And in order that our said Invention may be more fully under-
stood and readily carried into effect, we will proceed to describe the
means pursued by us.
:
DESCRIPTION OF THE DRAWING.
Figure 1, shews a side view, and Figures 2, 3, and 4, show two
plans and a section of the form of dies and apparatus used in
carrying out our Invention. a, is the moulding orifice, and b, the.
main core by which, if used alone, pipes would be made in the
ordinary manner, and would be solid at the sides. c, c, are a series
of small cores, the stems of which are fixed into the ring d, or other
suitable means of support at the back of the orifice a. . These small
cores c, are at equal distances apart; hence, when clay or plastic
brick earth is forced through the moulding orifice a, in place of the
sides of the pipe being made solid, as would be the case if the cores
c, c, were not used, each of the cores c, will produce a longitudinal
passage or opening through the sides of the pipes, by which the
pipes thus made will not only be lighter and stronger, but will dry
and burn better than when the clay or material at the sides of the

page_text: pipe is made solid, as heretofore, when making such descriptions of
pipes; and these forms of pipes will be found more useful, as they
will not require to have sockets made thereto, for, by simply
employing pins or pegs in the openings made by the cores c, the
several lengths of pipe may be readily connected together, and they
will thus be ensured against allowing one length of pipe descending
without others.
Having thus described the nature of our said Invention, we would
have it understood that what we claim is, the making of pipes with
longitudinal openings through the sides, by employing a series of
small cores in the moulding orifice, through which clay or brick
earth is expressed in order to make pipes.
In witness.whereof, I, the said George Samuel Whitton, have
hereunto set my hand and seal, this Fourth day of August,
in the year of our Lord One thousand eight hundred and
fifty-three.
Witness,
S. CARPMAEL.
GEORGE SAMUEL WHITTON. (L.S.)
