page_text: LETTERS PATENT to William Webb, of 17, Evelyn Street, New Town,
Deptford, in the County of Kent, for the Invention of "IMPROVE-
MENTS IN JOINTS OR CONNECTIONS FOR UNITING THE ENDS OF SOFT METAL
PIPES TO ONE ANOTHER AND TO OTHER PIPES AND COCKS AND UNION PIECES."
"
Sealed the 7th November 1871, and dated the 28th August 1871.
PROVISIONAL SPECIFICATION left by the said William Webb at the
Office of the Commissioners of Patents, with his Petition, on the
28th August 1871.
I, WILLIAM WEBB, of 17, Evelyn Street, New Town, Deptford, in
the County of Kent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN JOINTS OR CONNECTIONS FOR UNITING THE ENDS OF Sorr
METAL PIPES TO ONE ANOTHER AND TO OTHER PIPES AND COCKS AND UNION
PIECES," to be as follows:-
The object of this Invention is to do away with the necessity of solder
joints for connecting lead and other soft metal pipes one to another, or
for soldering screw union pieces to the ends of soft metal pipes for

page_text: connecting them to the ends of pipes of iron or other metal, or to cocks
or unions.
For the purpose of connecting together the ends of two lead or soft
metal pipes I slip on to each of the pipes an iron collar or ring, and
spread out the ends of the two 'pipes so as to form a flange around cach 5
end at right angles to it. The collars have threo or other number of
holes formed through them. Screw bolts are passed through the holes
in the two collars, and nuts are screwed on to these bolts. so as to
draw together the two collars and nip between them the flanges at the
ends of the two pipes. The soft metal flanges are thus squeezed together 1
until a perfectly water-tight joint is obtained. Paint or grease may be
smeared over the faces of the flanges before bringing them together to
facilitate the making of a perfectly water-tight joint.
For connecting the end of a lead or soft metal pipe to the end of an
iron pipe a ring or collar is screwed on to the end of the iron pipe, ]
whilst a similar collar is slipped on to the end of the soft metal pipe,-
and the end of the soft metal pipe is spread outwards to form a flange
as before described. The two collars are then drawn together by bolts
and nuts, and a perfectly water-tight joint is thus formed.
In a similar manner lead or soft metal pipes may be connected to the
ordinary brass stop-cocks, or screw ferrules, or driving ferrules, which
are commonly used for making connections with the mains. . The end of
a lead or soft metal pipe may also similarly be connected to the side of
another pipe to form a T joint, a clip piece being slipped on to one pipe,
and the end of such pipe being spread out and fitted approximately to
the side of the other pipe to which it is to be joined. A clip piece is.
placed on to this latter pipe, and the two clip pieces are drawn together
by screw bolts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Webb in the Great Seal Patent Office 30
on the 26th February 1872.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WEBB, of 17, Evelyn Street, New Town, Deptford, in the County of
Kent, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Webb, Her special license
that I, the said William Webb, my executors, administrators, and
assigns, or such others as I, the said William Webb, 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 "IMPROVEMENTS. IN
JOINTS OR CONNECTIONS FOR UNITING THE ENDS OF SOFT METAL PIPES TO ONE
ANOTHER AND TO OTHER PIPES AND COCKS AND UNION PIECES," upon the con-
dition (amongst others) that I, the said William Webb, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, 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 I, the said William Webb, 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 :-
1
The object of this Invention is to do away with the necessity of solder
joints for connecting lead and other soft metal pipes one to another, or
for soldering screw union pieces to the ends of soft metal pipes for
connecting them to the ends of pipes of iron or other metal or to cocks
or unions.
For the purpose of connecting together the ends of two lead or soft
metal pipes I slip on to each of the pipes an iron collar or ring, and
spread out the ends of the two pipes so as to form a flange around each
end at right angles to it. The collars have three or other number of
holes formed through them. Screw bolts are passed through the holes
in the two collars, and nuts are screwed on to these bolts so as to draw
together the two collars and nip between them the flanges at the ends

page_text: thus drawn together, and they squeeze between them the flanges of the
pipes, and these being of soft metal are compressed until they fit closely
one to another, and a tight joint is formed. As before stated, white
lead or paint may be smeared over the face of the flanges previous to
bringing them together to facilitate the making of a tight joint.
At Figure 3 the end of a lead pipe is shown connected by a similar
joint with a brass cock or tap. In this case one of the washers 6 has a
screw thread cut in it, and is screwed on to the end of the stem of the
cock or tap. The end of the soft metal pipe is formed into a flange as
before described, and the collar b, which has been placed around the
pipe is drawn up to the collar screwed on to the cock or tap by bolts
and nuts.
At Figure 4 is shewn a side view of a T joint formed in the manner
above described; and Figure 5 shows a transverse section of the same.
In this case the end of the soft metal pipe a, which is to be connected
to the side of the pipe a', is passed through a central hole in the clip
piece b, the form of which is clearly shewn by the Drawing. The end of
the pipe is then slightly coned outwards, and is cut to fit approximately
to the side of the pipe a'; a hole a³ is bored in the side of this latter
pipe, and a clip piece 6 is placed on to the side of the pipe opposite to
the hole bored in it; the clip pieces 6 and 6¹ are then drawn together
by the screw bolts and nuts c, c. By this means the end of the soft
metal pipe a is compressed against the side of the pipe a', and a tight
joint is formed.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim as
my improvements in joints or connections for uniting the ends of soft
metal pipes to one another, and to pipes, cocks, and union pieces,
are,―
First. The forming the joint or connection for uniting the ends of two
soft metal pipes, substantially as herein described and shewn at
Figures 1 and 2.
Second. The forming the joint or connection for uniting the end of a
soft metal pipe to the end of another pipe, or to a cock or union piece,
& substantially as herein described and shown at Pienso 3

page_text: Third. The forming the joint or connection for uniting the end of the
soft metal pipe to the side of another pipe so as to form a T joint, sub-
stantially as herein described and shewn at Figures 4 and 5.
In witness whereof, I, the said William Webb, have hereunto set..
my hand and seal, this Third day of February, in the year of our 5
Lord One thousand eight hundred and seventy-two.
