66, Chancery Lane, in the County of Middlesex, Civil Engineer,
for the Invention of "AN IMPROVED MODE OF CONNECTING GAS, WATER,
OR OTHER PIPES."-A communication from abroad by Monsieur
Galasse-Ketin, of Brussels, in the Kingdom of Belgium,
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 11th October 1873.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "AN IMPROVED MODE OF CONNECTING
GAS, WATER, OR OTHER PIPES," to be as follows:-
The object of this Invention is to obviate the necessity for using pipes
with socket ends for ensuring tight joints, and to permit of the use of*
pipes made with a uniform barrel throughout which will allow of any

page_text: desired length being cut off and coupled up to complete a run of
pipe.
In carrying out the Invention a series of annular grooves or hollows
is formed round the ends of the lengths required to be joined. The
grooved ends are introduced into a leaden sleeve of double conical form,
externally, and having at the middle of its length an internal annular
rib which forms an abutment for the onds of the pipes to be coupled.
The joint is completed by forcing over the opposite ends of the leaden
sleeve conical iron rings, which when driven home by means of a
hammer or cramp will compress the lead into [the annular grooves or
hollows on the ends of the pipes. By this means not only a strong and
perfectly water and air tight joint will be obtained, but owing to the
compressibility of the internal annular leaden rib space for the expansion
of the metal pipes will be given.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Edward Newton in the Great Seal
Patent Office on the 10th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of October, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Edward Newton,
Her special licence that I, the said Henry Edward Newton, my
executors, administrators, and assigns, or such others as I, the said
Henry Edward Newton, 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 IMPROVED MODE OF CONNECTING
Gas, WATER, OR OTHER PIPES," being a communication to me from abroad

page_text: by Monsieur Galasse-Ketin, of Brussels, in the Kingdom of Belgium,
upon the condition (amongst others) that I, the said Henry Edward
Newton, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
3 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 Henry Edward Newton, 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, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say):
-
The object of this Invention is to obviate the necessity for using pipes
with socket ends for ensuring tight joints and to permit of the use of
pipes made with a uniform barrel throughout which will allow of any
desired length being cut off and coupled up to complete a run of pipe.
In carrying out the Invention a series of annular grooves or hollows is
formed round the ends of the lengths required to be joined. These grooved
ends are introduced into a leaden sleeve of double conical form externally,
and having at the middle of its length an internal annular rib which
forms an abutment for the ends of the pipes to be coupled. The joint
is completed by forcing over the opposite ends of the leaden sleeve
conical clamping rings, which when driven home by means of a hammer
or cramp will compress the lead into the annular grooves or hollows on
the ends of the pipes. By this means not only a strong and perfectly
water and air tight joint will be obtained, but owing to the com-
pressibility of the internal annular leaden rib space for the expansion of
the metal pipes will be given.
In the accompanying Drawing, Fig. 1 represents in section a joint
complete; Fig. 2 represents also in section a joint in course of com-
pletion, the iron rings not being driven home; Fig. 3 is an outside view
of the completed joint, and Fig. 4 represents the end of a pipe with the
joint in section. The same letters indicate corresponding parts in all
the Figures.

page_text: A, A, are the pipes; B, the leaden sleeve; C, C, the conical rings;
D, the grooves or hollows into which the lead is compressed.
In order to obtain a good setting of the lead in the grooves of the
pipes it is only necessary in pipes of small diameter to hammer up the
conical rings into position, but for pipes of larger diameter the rings are
first driven on by blows from a hammer and then forced home by the
aid of a cramp or spanner, such as that shewn at Figures 5, 6, and 6ª,
assisted by hammer blows. This system of joints can be applied to
pipes of any form, such for instance as that shewn in Figures 7 and 8,
in which pipes of an elliptic form are employed.
In elbows or angles notwithstanding the great solidity of this system'
of joint, it is just possible that under the effect of the continued blows of
a rammer while ramming the earth round the pipes the leaden sleeve
may give way, and in order to avoid this sort of accident I cast on to.
the ends of the pipes brackets or ears, and by means of wrought-iron
bands which are tightened up by tightening pins or wedges a compact
and strong joint is made, and a rupture of the leaden sleeve is impossible.
This addition is shewn in Figures 9 and 10, in which E are the wrought-
iron bands; F, the cast-iron brackets; and G, the tightening pins or
wedges.
In some cases I replace the conical clamping rings by a band of iron,
the two extremities of which can be drawn together by means of a.
strong bolt and nut, as shewn at Fig. 11, in which O is the iron band.
and D the bolt and nut.
Great difficulty has been experienced in the construction of the leaden
sleeves, as the ordinary process of moulding them is found to be too
costly. The mode employed in the moulding of these sleeves is shewn
in Figures 12, 13, 14, 15, 18, 19, 20, 21, 22, 28, and 24.
In Figures 12, 13, 14, and 15, the mould is shewn ready for use, and
in Figures 18, 19, 20, and 21, the parts of the mould are shown in
detail.
The completed leaden sleeve is shewn in Figures 22, 23, and 24, in
which Fig. 22 is a side view, 23 a plan view, and 24 a cross section.
In the different Figures H is a funnel to receive the molten lead;
I, the cheeks of the funnel; J, the outer casing of the mould; K, K, a
divided core, and L, the leaden sleeve.

page_text: Figures 16 and 17 shew in plan view and in longitudinal section a
mandril in cast iron intended to serve as a core on which to make the
conical iron rings O.
Having now described the nature of the said Invention as communi-
cated to me by my foreign correspondent, and having explained the
manner of carrying the same into effect, I wish it to be understood that
under the above in part recited Letters Patent I claim, connecting gas,
water, and other pipes, in the manner and for the purpose above
described.
In witness whereof, I, the said Henry Edward Newton, have
hereunto set my hand and seal, the Tenth day of April, in the
year of our Lord One thousand eight hundred and seventy-
four.
