page_text: LETTERS PATENT to John Roberts, of West Bromwich, in the
County of Stafford, Ironfounder, and Jabez Morgan, of Kidder-
minster, in the County of Worcester, Manager of Works, for the
Invention of "IMPROVEMENTS IN JOINING METALLIC PIPES."
Sealed the 17th July 1868, and dated the 27th January 1868.
PROVISIONAL SPECIFICATION left by the said John Roberts and
Jabez Morgan at the Office of the Commissioners of Patents, with
their Petition, on the 27th January. 1868.
We, JOHN ROBERTS, of West Bromwich, in the County of Stafford,
Ironfounder, and JABEZ MORGAN, of Kidderminster, in the County
of Worcester, Manager of Works, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN JOINING METALLIC PIPES," to be as
follows:-
Our Invention relates to such metallic pipes as are ordinarily used
for conveying water, gas, and steam, and for other like purposes, and
consists of the improvements herein-after described, whereby the said
pipes are joined securely and expeditiously.

page_text: In joining pipes according to our Invention we make the ends to
be joined flat so that when they are pressed together with an india-
rubber or other washer between them they make an air and water-
tight joint. On the outside and near the end of each pipe we make
a series of three or other number of projections, the outer sides, that
is the sides most distant from each other, being inclined in opposite
directions. We make a detached collar or ring of metal of a size
suitable to fit on the ends of the pipes to be joined and having on its
interior surface two series of projections equal in number to those in
the ends of the pipes. The one series of projections is at such a distance
from the other series that when the ends of the two pipes are brought
together the projections on the said ends of the pipes fit between them.
On sliding the collar or ring on the ends of the pipes it is turned into
such a position that its projections are not presented to those on the
pipes, it is then moved so as to bring it equally over the ends of the
two pipes and a motion of partial rotation is given to it. The pro-
jections on the collar or ring engage on each side the inclined pro-
jections on the pipes and draw the ends of the pipes, together by a
wedging action, after the ends of the pipes have been brought together
with sufficient tightness by the turning of the collar or ring the space
between the ring and the ends of the pipes may be filled by caulking;
this however is not necessary as the joint is tight and the ends of
the pipes are securely held together without caulking.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Roberts and Jabez Morgan in the Great Seal
Patent Office on the 20th July 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
ROBERTS, of West Bromwich, in the County of Stafford, Ironfounder,
and JABEZ MORGAN, of Kidderminster, in the County of Worcester,
Manager of Works, send greeting.

United Kingdom of Great Britain and Ireland, the Channel Islands,,
and Isle of Man, an Invention for "IMPROVEMENTS IN JOINING METALLIC
PIPES,"
upon the condition (amongst others) that we, the said John
Roberts and Jabez Morgan, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under
the hand and seal of one of us or them, 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 we, the said John Roberts and Jabez Morgan,
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 :-
Our Invention relates to such metallic pipes as are ordinarily used
for conveying water, gas, and steam, and for other like purposes, and
consists of the improvements herein-after described, whereby the said
pipes are joined securely and expeditiously.
In joining pipes according to our Invention we make the ends to
be joined flat so that when they are pressed together with an india-
rubber or other washer between them they make an air and water tight
joint. On the outside and near the end of each pipe we make a series
of three or other number of projections, the outer sides, that is, the sides
most distant from each other, being inclined in opposite directions. We
make a detached collar or ring of metal of a size suitable to fit on the
ends of the pipes to be joined, and having on its interior surface two series
of projections equal in number to those on the ends of the pipes. The
one series of projections is at such a distance from the other series that
when the ends of the two pipes are brought together the projections on
the said ends of the pipes fit between them; on sliding the collar or ring
on the ends of the pipes, it is turned into such a position that its
projections are not presented to those on the pipes. It is then moved.

page_text: so as to bring it equally over the ends of the two pipes and a motion
of partial rotation is given to it. The projections on the collar or ring
engage on each side the inclined projections on the pipes and draw
the ends of the pipes together by a wedging action. After the ends
of the pipes have been brought together with sufficient tightness by
the turning of the collar or ring the space between the ring and the
ends of the pipes may be filled by caulking. This however is not
necessary as the joint is tight and the ends of the pipes are securely held
together without caulking.
Having explained the nature of our Invention we will proceed to
describe, with reference to the accompanying Drawing, the manner in
which the same is to be performed.
Figure 1 represents in side elevation the ends of two metallic pipes
joined according to our Invention, and Figure 2 is a longitudinal section
of the same; Figure 3 represents transverse sections of the collar or
ring separately, the said sections being taken at right angles to one
another; Figure 4 represents in elevation the two pipes without the
collar or ring, and Figure 5 is a transverse section of one of the pipes
taken through the dotted line 6, Figure 4. The same letters of reference
each Figure of the Drawing.
are employed to indicate the same parts in
c, d, are the two pipes to be joined together and e is the detached
metallic collar or ring, which is used to connect the said pipes. On
the outside and near the end of each of the pipes c, d, is a series of
three projections f, f, the sides of the said projections furthest from
the end of the pipe to be joined being inclined, the sides of the pro-
jections on one pipe being inclined in an opposite direction to that of
the sides of the projections on the other pipe as best seen in Figure 4.
The detached ring or collar e is made of a size suitable to fit on the
exterior of the ends of the pipes c, d, on the interior surface of the said
collar or ring e two series of projections 9, 9, equal in number to the
projections ff, on the end of each of the pipes c, d, are made. The
shape of these projections g, g, on the ring or collar e is best seen in
Figure 3. The inner side of each of the projections g, g, is inclined
at an angle similar to that of the inclined sides of the projections f.
In joining the ends of the pipes c, d, together an india-rubber or other
washer is put between the flat ends of the pipes and the detached
collar or ring e is placed on the ends of the pipes in such a position
that its projections g, g, are not presented to the projections f, f, on

page_text: the pipes, that is, the projections g, g, on the ring or collar are made
to coincide with the spaces i between the projections on the said pipes..
By sliding the collar or ring e when in this position it is brought
equally over the ends of the two pipes so that the inner sides of each.
series of its projections 9, 9, are situated nearly in a line with the,
inclined sides of the series of projections f on the ends of the pipes c, d.
By then giving a motion of partial rotation to the said collar or ring e,
by means of a spanner or other convenient instrument, the projections;
g, g, engage on each side of the inclined projections. f, f, on the
pipes c, d, and draw the flat ends of the said pipes together by a
wedging action as represented in Figure 2, the ends of the two pipes
are thereby securely joined together, an air and water-tight joint being
made by the washer h placed between the flat ends. In order to give
internal support to the washer ha recess at i is made in the interior
of each end of the pipes c, d, in which recesses a ring of hoop iron k
is placed as represented in Figure 2. The space between the collar
or ring e, and the exterior of the ends of the pipes c, d, may be filled
if desired by caulking. In order to draw and hold the ends of the
pipes c, d, securely together while the collar or ring e is turned we
make use of the arrangement of parts represented in side elevation in
Figure 7 and end elevation in Figure 8 of the Drawing. Near the
end of each pipe is a bead against which is placed a semicircular
clip m, the said clips being jointed at n to a longitudinal bar o; p is
a rod having a head or nut at one end and a screw at the other end.
The said rod p is passed through holes in the vertical arms of the
clips m and a screw nut q is placed upon the screwed end of the said
rod p. By turning the nut q the two clips m, m, are drawn together
and by bearing against the beads 1, 1, press or draw together the ends.
of the two pipes and hold them securely in that position while they are
joined by the turning of the collar or nut e. Instead of making a
series of three inclined projections on the ends of the pipes, two inclined
projections only may be made on each end of the pipes as represented
in cross section in Figure 6. Or a series of more than three projections
may be made on the end of each pipe, a corresponding number of
projections being made on the interior surface of the detached collar
or ring.
Having now described the nature of our Invention, and the manner
in which the same is to be performed, we wish it to be understood that
we do not limit ourselves to the precise details herein described and

page_text: illustrated as the same may be varied without departing from the nature
of our Invention; but we claim as our Invention the improvements
in joining metallic pipes herein-before described and illustrated in the
accompanying Drawing, that is to say, joining the said pipes by means
of inclined projections on the outside of their ends, with which inclined
projections other inclined projections on the interior surface of a
detached metallic collar or ring are made to engage, and by a wedging
action to draw the ends of the pipes together, substantially as described
and illustrated.
In witness whereof, we, the said John Roberts and Jabez Morgan,
have hereunto set our hands and seals, this Eighteenth day of
July, in the year of our Lord One thousand eight hundred and
sixty-eight.
Witness,
GEORGE SHAW.
