Year: 1854

page_text: LETTERS PATENT to John Fisher Williams, of 19, Artillery Place West,
Bunhill Row, for the Invention of "IMPROVEMENTS IN JOINING CAST-IRON
TUBES."
Sealed the 27th February 1855, and dated the 29th August 1854.
PROVISIONAL SPECIFICATION left by the said John Fisher Williams
at the Office of the Commissioners of Patents, with his Petition, on
the 29th August 1854.
1, JOHN FISHER WILLIAMS, of 19, Artillery Place West, Bunhill Row, do
hereby declare the nature of the Invention for IMPROVEMENTS IN JOINING
CAST-IRON TUBES" to be as follows:-
This Invention has for its object the employment of asphalted felt or other
flexible compound of fibrous (whether animal or vegetable), and any variety
of bituminous, gummy, or resinous substances, in forming the joints of cast-iron
pipes. For this purpose the ends of the pipes are, by preference, cast so as to
be capable of entering into each other, by which a socket joint is formed; the
socket end being formed with an abutment surface at any angle, which may be
flat, concave, or convex, and has a kind of recess into which the asphalted felt
or the other stated packing is compressed by the end of the adjoining pipe,
which enters into the socket, which end surface is formed to correspond; the
two pipes being connected and tightened together to resist pressure by screw
pins or other suitable fastenings passing through lugs or projections cast on
each end of the pipes; the joint in the socket also being additionally secured
by a corking of the asphalted felt or the other suitable packing.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FISHER WILLIAMS, of 19, Artillery Place West, Bunhill Row, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of August, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Fisher Williams, Her special licence that I, the said
John Fisher Williams, my executors, administrators, and assigns, or such
others as I, the said John Fisher Williams, 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 JOINING CAST-IRON. TUBES," upon the condition (amongst
others) that I, the said John Fisher Williams, 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 John Fisher Williams, 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 the employment of asphalted felt or other
flexible compound of fibrous (whether animal or vegetable), and any variety of
bituminous, gummy, or resinous substances, in forming the joints of cast-iron
pipes. For this purpose the ends of the pipes are, by preference, cast so as to
be capable of entering into each other, by which a socket joint is formed; the
socket end being formed with an abutment surface at any angle, which may be
flat, concave, or convex, and has a kind of recess into which the asphalted felt
or the other stated packing is compressed by the end of the adjoining pipe,
which enters into the socket, which end surface is formed to correspond; the
two pipes being connected and tightened together to resist pressure by screw
pins or other suitable fastenings passing through lugs or projections cast on

page_text: by a caulking of the asphalted felt or the other suitable packing.
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing shows a longitudinal section of a joint for cast-iron tubes
according to my Invention. a and b are the ends of two cast-iron tubes. The
tube a is made with a socket, and such socket is cast with two or more lugs
or projections c thereon. The end of the tube b is also made with projecting
lugs d; these lugs c and d are drawn and held together by screw bolts and
nuts e, e, as shewn. I would, however, remark, that it is not new to connect
tubes made with socket and spicket ends by means of screw bolts and nuts;
I do not therefore claim the same, the peculiarity of my Invention consisting
of the mode of rendering such tubes fluid-tight without running lead into the
joints. For this purpose I form the ends or parts f, f, where the two tubes
come together, either flat, concave, or convex, either as shewn or angular, and
in such manner as to receive between these parts a layer of asphalted felt or
other flexible compound of fibres or other of the substances mentioned, as is
shewn by the red color; and when the ends of the two tubes a and b have
been tightly drawn together by the screw bolts and nuts, I caulk the space g, g,
with pieces of felt or like compounds of fibres or other substances. It is not
essential that the parts g should be plain, as shewn, but they may be made
with grooves.
Having thus described the nature of my Invention, I would have it under-
stood that what I claim is, combined means of joining cast-iron tubes herein
described.
In witness whereof, I, the said John Fisher Williams, have hereunto set
my hand and seal, this Twenty-seventh day of February, in the year of
our Lord One thousand eight hundred and fifty-five.
