AN IMPROVED GAS AND WATER-TIGHT JOINT TO PIPES AND TUBES
Year: 1870

page_text: LETTERS PATENT to Jules Crouzières, of Museum Street, Bloomsbury,
in the County of Middlesex, Engineer, for the Invention of "AN
IMPROVED GAS AND WATER-TIGHT JOINT TO PIPES AND TUBES."
PROVISIONAL SPECIFICATION left by the said Jules Crouzières at the
Office of the Commissioners of Patents, with his Petition, on the
11th May 1870.
I, JULES CROUZIÈRES, of Museum Street, Bloomsbury, in the County
of Middlesex, Engineer, do hereby declare the nature of the said Invention
for "AN IMPROVED GAS AND WATER-TIGHT JOINT TO PIPES AND TUBES," to be
as follows:
The object of my Invention is to provide an easy, rapid, and econo-
mical means of perfectly connecting the ends of pipes or tubes of large
or of small diameter, and also of disconnecting them with equal facility
for removal and substitution.
The main feature of my improved joint is the use of a shifting jacket
or coupling box moving freely along the pipes to be jointed and provided

page_text: with an opening for introduction of the cement or lead with which the
joint is to be made.
On the accompanying Sheet of Drawing Figure I. is a longitudinal
section through a joint made according to my Invention; Figure II. an
elevation of same; and Figure III. an end view.
A, A, pipes; B, jacket; C, opening in jacket for introduction of cement
or lead; D, rings on pipes forming recesses for cement or lead; D', rings
on jacket to give further security to the joint; E, space between the
pipes and the shifting jacket, permitting it to be easily shifted right and
left along the pipes; F, small orifice made in jacket when lead is used
for making the joints.
The operation of making the joint is as follows:-The ends of the
pipes A being brought close together the jacket B is drawn along the
one or the other until its opening C is in a line with the section of the
two pipes. The openings E are temporarily closed by any available
means. The cement or lead is then poured in at C until the jacket is
filled and the joint is then complete. To disconnect the pipes it is only.
necessary to melt the lead or cement by heating the exterior of the jacket
and to drive the jacket along the pipe right or left as may be convenient.
When lead is used it will run out by the opening F when the jacket is
heated and be easily caught and reserved for making a fresh joint. The
cement which I prefer to use in making this joint is that invented by
me, and patented under the No. 3274, and date of 13th November 1869,
but lead or any suitable composition may be used. The rings D, D¹,
may be replaced by any kind of projection or recess, and none are
absolutely necessary to the security of this joint, particularly if the pipes.
are laid horizontally. The jacket shewn on the Drawing is of an oval
form, but it may be square, polygonal, or of any desired shape, and be
made of cast iron or of any metal or material which may be found
suitable for such purpose.

page_text: WHEREAS Her most Excellent, Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of May, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jules Crouzières, Her special licence that
I, the said Jules Crouzières, my executors, administrators, and assigns,
or such others as I, the said Jules Crouzières, my executors, adminis-
trators, 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 GAS AND WATER-TIGHT
JOINT TO PIPES AND TUBES," upon the condition (amongst others) that I,
the said Jules Crouzières, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, 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
bo filed in the Great Scal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jules Crouzières, 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 accompanying
Drawing forming a part of this Specification:-
The object of my Invention is the provision of easy, rapid, and
economical means for perfectly connecting the ends of pipes or tubes of
either large or small diameter, and also for disconnecting them with
equal facility to allow of the removal and replacement.
The main feature of my improved joint is the use of a movable or
shifting sleeve jacket or coupling box, which is formed to slip freely over
the pipes to be jointed, and is provided with an opening for the intro-
duction of cement or lead with which the joint is to be made tight.

page_text: A, A, are the ends of the pipes to be united; B is the sleeve or jacket;
C is an opening in the said sleeve for the introduction of the cement or
lead; D, D, are rings on the pipes forming recesses for the cement or
lead; D¹, D¹, are rings on the sleeve or jacket to give further security
to the joint; E is a space between the pipes and the shifting jacket,
permitting it to be easily shifted either to the right or left along the
pipes; F is a small orifice in the sleeve or jacket whereby the lead used
for making the joint is removed when desired. The joint is made in the
following manner:-The ends of the pipes A being brought close
together, the sleeve or jacket B is drawn along the one or the other ]
until its opening C is in a line with the line of junction of the two
pipes the openings E, F, are temporarily closed by any convenient
means. The cement or lead is then poured into the aperture C until
the sleeve or jacket is filled, and the joint is then complete.
To disconnect the pipes it is only necessary to melt the lead or cement 1
by heating the exterior of the jacket, and to drive the jacket along the
pipe right or left, as may be convenient. When lead is used it will run
out through the opening F when the jacket is heated, and may be easily
caught and reserved for making a fresh joint.
The cement which I prefer to use in making this joint is that invented 2
by me, and described in the Specification of an Invention for which
Letters Patent have been obtained, bearing date the 13th day of
November, A.D. 1869, No. 3274, but any suitable material or com-
position may be used.
The rings D, D', may be replaced by any kind of projection or recess, 2
or may be entirely dispensed with, none being absolutely necessary to
the security of this joint, particularly if the pipes are laid horizontally.
The sleeve or jacket shewn on the Drawing is of an oval form, but
it may be square, polygonal, or of any desired shape, and may be
made of cast iron, or of any metal or material which may be found 3
suitable for such purpose.
Having thus fully described the said Invention, and shewn how the
same may be conveniently and advantageously carried into practice, I
wish it understood that I claim,-
First. A moveable jacket or sleeve constructed to slide freely over the 3
pipes to be united, and with an interior space for the reception of lead
or cement to surround the said pipes, and provided with apertures for the

page_text: admission and removal of the lead or cement, and with or without the
rings, projections, or recesses, substantially as set forth for the purpose
specified.
Second. Making a tight joint between two pipes by the combination
of the aforesaid sleeve with the rings, projections, or recesses on the ends
of the said pipes, and with lead, cement, or other suitable filling material,
substantially as set forth.
In witness whereof, I, the said Jules Crouzières, have hereunto
set my hand and seal, this Tenth day of November, in the year
of our Lord One thousand eight hundred and seventy.
Witness,
E. C. JACKSON.
