PROVISIONAL SPECIFICATION.
Improvements in Mounting Pipes.
I, CHARLES JACKSON of 224 Herbert Road Birmingham in the County of Warwick
Engineer do hereby declare the nature of this Invention to be as follows:-
-
This Invention has for its object improvements in mounting pipes.
Upon the stem of the bowl I provide a ring or ferrule with a screw thread upon it,
and this screws into a connecting piece. The connecting piece is a tube of thin metal
with a screw thread indented into it corresponding to the screw thread upon the ring
or ferrule. Within the tubular connecting piece a disc or partition is fixed and a
small inner tube passes through this disc or partition and it is fixed to it projecting on
either side. When the connecting piece is screwed on to the ring or ferrule upon the
stem of the bowl the projecting end of the inner tube enters the passage in the stem
of the bowl and the end of the stem comes to abut firmly against the disc or partition
and so makes a secure joint.
An advantage in this construction is that the connecting piece can he readily
unscrewed from the stem of the bowl and the parts are not liable to lock fast together
as is the case in pipes mounted in the ordinary manner.
When an amber mouth-piece is employed 1 make a secure attachment between the
amber and the connecting piece in the following manner :-I make a very thin ring
of silver or other metal to tightly fit upon the end of the amber mouth-piece and I
perforate this ring with a number of holes; I then cement the ring on to the mouth
piece with shellac or other cement. The solvent is able to evaporate from the cement
by the, perforations in the ring and consequently sets hard upon the amber, and so the
ring. becomes, very firmly fixed. This ring fits accurately into the tubular connecting
piece and comes to abut upon the disc or partition within it on the side opposite to
that which meets the end of the stem of the bowl. The amber with the metal ring
upon it is set into the connecting piece with cement, and so a permanent joint is
made.
By the device which I have described of first cementing a thin perforated metal
ring upon the amber before cementing it into the connecting piece the difficulty
heretofore experienced of securely fixing the amber in the connecting piece is over-
come.

1, CHARLES JACKSON of 224 Herbert Road Birmingham in the County of Warwick
Engineer do hereby declare the 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 :-
This Invention has for its object improvements in mounting pipes.
Upon the stem of the bowl I provide a ring or ferrule with a screw thread upon it,
and this screws into a connecting piece. The connecting piece is a tube of thin metal
with a screw thread indented into it corresponding to the screw thread upon the ring
or ferrule. Within the tubular connecting piece a disc or partition is fixed and a
small inner tube passes through this disc or partition and it is fixed to it projecting on
either side. When the connecting piece is screwed on to the ring or ferrule upon the
stem of the bowl the projecting end of the inner tube enters the passage in the stem
of the bowl and the end of the stem comes to abut firmly against the disc or partition
and so makes a secure joint.

as is the case in pipes mounted in the ordinary manner.
When an amber mouth-piece is employed I make a secure attachment between the
amber and the connecting piece in the following manner :-I make a very thin ring
of silver or other metal to tightly fit upon the end of the amber mouth-piece and I
perforate this ring with a number of holes, I then cement the ring on to the mouth-
piece with shellac or other cement. The solvent is able to evaporate from the cement
by the perforations in the ring and consequently sets hard upon the amber, and so the
ring becomes very firmly fixed. This ring fits accurately into the tubular connecting
piece and comes to abut upon the disc or partition within it on the side opposite to
that which meets the end of the stem of the bowl. The amber with the metal ring
upon it is set into the connecting piece with cement, and so a permanent joint is
made.
By the device which I have described of first cementing a thin perforated metal
ring upon the amber before cementing it into the connecting piece the difficulty
heretofore experienced of securely fixing the amber in the connecting piece is over-
come.
In order that my said Invention may be more fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a complete pipe.
Figure 2 is a longitudinal section of part of the same to a larger scale.
A is the stem of the bowl of the pipe. B is a ferrule attached to it. As shown in
the drawings it consists of a thin metal tube with a screw thread indented into it
which fits into a rough screw thread formed in the material of the stem of the pipe,
but it may be otherwise secured. C is the screw connecting piece which is made in
one with a disc or partition D and tube E.
Figure 3 is a longitudinal section of part of an aniber mouth-piece secured in this
manner. The same letters are used as before, the only difference being that the con-
necting piece is secured to the mouthpiece by means of the perforated ring F, which is
shown separately in elevation at Figure 4.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A connecting piece for securing the mouth-piece of pipes consisting of a tube,
one end of which receives the end of the stem of the bowl and the other end the end
of the mouth-piece and provided with a disc or partition, separating the stem from
the mouth-piece, and with or without an inner tube substantially as described.
2. The method of securing an amber or other mouth-piece to a tube or intermediate
piece consisting of cementing to it a perforated metallic tube substantially as described.
3. Pipe mountings substantially as described and shown in the drawings.
