PROVISIONAL SPECIFICATION.
Improvements relating to the Joining or Connecting of Pipes.
I, NICOLAS CLOUTIER (otherwise known as Nicolas Cloutier-Colson), of 5, Rue
Mazagran, Paris, in the Republic of France, Engineer, do hereby declare the
nature of this invention to be as follows:-
The present invention has reference to a method of connecting water, gas,
steam, and other pipes together, or to their fittings, without the aid of solder.
•
The invention is applicable both to the connection of pipes of soft material,
such as lead, and of pipes of hard material, such as porcelain, etc..
In joining together the ends of two leaden or other soft pipes, I insert each into
the smaller end of a socket of hard metal, of a form conical for the greater
portion of its length. The pipe is then spread out, to fill the socket, by the
insertion internally of a short piece of conical tube. Each socket has, at its
larger end, a collar which has an internal thread and also .an. external thread.
Into the inner thread is screwed a washer provided on its face with a recess for
packing, so that when the pipes are placed end to end, the washers touch, and
make with the packing a tight joint. The whole is held firmly in position by a
nut which is screwed onto the outside of the sockets at their point of junction,
so as to force them close together, and hold the washers aforesaid in permanent
contact.
As a modification of this arrangement, the washers may be omitted, and a
single piece of tube, of externally oval or double-cone form, is inserted half into
the end of one pipe, and half into the end of the other.
A packing, in this case, is preferably used at the point of junction of the outer
sockets, which are compressed together end to end by a locking nut.
In the case of pipes of hard material, which pipes are incapable of expansion,
the conical joining tubes are fitted to the outside, instead of to the inside, of the
pipe ends, and in this way a filling for the external conical sockets is provided.
In other respects, the arrangement does not differ from that first described.
I may remark that this joint gives complete tightness, even under the highest
pressures, is much more practicable than the ordinary wiped joint, & does not
involve any undue expense in fitting or construction.

page_text: nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The present invention relates to a new form of union capable of being employed
for connecting water gas, steam and other pipes superseding the wiped joints of
solder until now used for joining two pieces of tube together, or a tube to its
fittings.
This union besides giving complete tightness and resisting the strongest pres-
sures is in use much more practical than similar existing unions and is hardly
more expensive.
In order that my invention may be fully understood I have shewn it in the
accompanying drawing.
Figure 1 shews in longitudinal section my union applied to a pipe of lead or
other malleable metal.
Figure 2 is a similar view shewing the invention adapted to a tube of glass,
porcelain iron or other rigid material and
Figure 3 is a similar view of a modification of the invention applied to a
malleable metal tube.
In Figures 1 and 2 a, a, are two pipes of malleable metal to be joined together
& b b are two pipes of rigid material. A A are a pair of truncated cones of
bronze copper, iron, ebonite, caoutchouc, glass or similar material, which are
placed (in the case of Fig. 1) in the inside of the soft metal tubes a a which are
capable of expansion, or (in the case of Fig. 2) outside the tubes of hard
metal and within the outer sockets C and D.
C and D are the outer sockets which form the union with the aid of the nut E.
F and G are two threaded washers screwed into the interior of the sockets C
and D and intended to maintain the cones A A in the opposite sides of the joint
thereby ensuring screwing up to the extent necessary to obtain absolute water
tightness.
The washers F and G have on their surfaces recesses to receive packings g of
caoutchouc, leather etc., which are in juxtaposition when the two parts of the
union are united together by screwing up the nut E thereby ensuring complete
tightness of the joint.

'
If I think fit I can use a double threaded washer made in one piece and a
double cone.
In Figure
I replace the two separate cones A A by a single double cone B.
C and D are the metal cone sockets of which D is formed with a threaded
collar d and C with a plain collar d'.
.
In the thickness of the collars I arrange a rabbet 6 6¹ for receiving the
collars c c¹ of the tubes a a.
B is a double cone of oval form of bronze copper, iron, ebonite, caoutchouc,
glass, porcelain &c., sloping from its middle part and forming the tight joint of
the union. E is the nut of a form adapted to engage with the collar d¹ and
to screw onto the collar d of the socket D thus serving to unite the parts of the
joint.
Having thus described the parts constituting my union I will now indicate
the mode of employing and placing the same.
In Figure 1 I pass the ends of the malleable tubes into the sockets C, 'D.
After manipulating the tubes to make them assume the form of the sockets I
place inside them the cones A A which I fix in their respective places by the
threaded washers F, G which I screw up as far as necessary. This effected it
only remains to unite the two parts of the union by means of the nut E.
In the case of Fig. 2 I place the cones A A between the sockets CD and the
tubes b, b; the screwing up is obtained as in the preceding arrangement.
In the case of Fig. 3 the ends of the tubes a a are passed each into its socket C
or D and the collars c c¹ are caused to embed themselves in the rabbets b b and

page_text: the tubes a a are expanded to give to them the form of the interior of the
sockets C and D.
The tubes thus fixed to the sockets the double cone B is inserted and the
sockets are drawn together by means of the nut E.
As is easily understood in giving a sufficient screwing up to the nut E (Fig. 3)
the two collars c, c', are caused to bear one against the other forming a primary
joint and the double cone B finds itself likewise compressed within the pipes
forming a second joint.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The union above described comprising truncated cones engaging with the ends
of the pipes to be joined in the manner explained and coöperating with external
sockets connected by a screw nut substantially as herein set forth.
