do hereby declare the nature of my invention for "IMPROVEMENTS IN APPARATUS
FOR CONNECTING SERVICE OR BRANCH PIPES TO MAIN PIPES ALSO SUITABLE FOR
CONNECTING AND REPAIRING PIPES to be as follows:-
""
My apparatus consists of a collar split into two halves so as to allow it to be
put on to the main pipes without having to break or disconnect them. When in
position the two halves of the collar are bolted or otherwise fixed together. The
ends of the collar are provided with sockets into which lead is run or tight joints
are made between the socket and main pipes in any other ordinary way.
All around the inside of the collar there is a recess which when the halves of
the collar are together and in position forms a ring shaped space around the main.
At the side of one half of the collar there is a hole leading into this recess and the
hole is either screw threaded or has a socket on the outside of the collar so that a
service or branch pipe can be joined to the collar by screwing or packing in the
ordinary way or the collar may have several holes for several branches.
A rough hole having been cut in the main pipe the collar is fitted on so that
the hole opens into the above mentioned recess in order that the gas or other fluid
by passing around the ring shaped recess may be able to go out into the branch
pipe or pipes.
If the hole in the side of collar be omitted or closed the apparatus can be used
for stopping a leak in a pipe or for connecting the ends of two pipes.

either screw-threaded or has a socket on the outside of the collar so that a service
or branch pipe can be joined to the collar by screwing or packing in the ordinary

A rough hole having been cut in the main pipe the collar is fitted on so that the

passing around the ring shaped recess may be able to go out into the branch pipe
or pipes.
If the hole in the side of collar be omitted or closed the apparatus can be used
for stopping a leak in a pipe or for connecting the ends of two pipes.
In order that my invention may be fully understood and readily carried into
effect I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a transverse section and Figure 2 a longitudinal section of a
main pipe to which a branch pipe is attached by means of my apparatus-a is the
main pipe and b the branch pipe. cc are the two halves of the collar. d is the
ring shaped chamber around the main-e is a rough hole cut in the main.
ff are fillets or projections running round the inside of the two halves of the
collars and when these are in place and bolted together the fillets clip the main
firmly and act as stops for the lead g which is run in to form the joint. Other
means however may be employed for making a tight joint between the collar and
the main. The drawing only shows a single branch pipe which is screwed into a
boss on one half of the collar but as before explained the collar may be fitted for
several branches and the connections may be made in other ways.
Much time and labour is saved by employing this apparatus as only a rough
unthreaded hole has to be cut in the main and this is done in the most convenient
position and not of necessity at the end of the branch.
A better result also is obtained for the connection of the branch may be of any
length whereas in the present system it is limited to the thickness of the main-
the risk of splitting the main is diminished and even if a split occurs little or no
harm results.
Fractured mains and sockets can be repaired by this apparatus withou
disturbing the pipes whereas at present the fractured pipe has to be cut out and
replaced.
Instead of cutting a hole in the main the apparatus can be applied when laying

page_text: the main at the junction where two pipes abut against each other without making
a tight joint.
In some cases also the annular space around the split collar may be omitted but
in this case if a branch has to be taken off the hole in the main must be opposite
to the branch.
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:-
First, The apparatus for connecting service or branch pipes to mains consisting
of a split collar with or without the recess on its inside and provided with a hole
or holes for the reception of a branch pipe or pipes substantially as described.
Second. The apparatus for connecting or repairing pipes consisting of a split
collar with or without the recess on its inside and with ends such that tight joints
can be made around the pipes or pipe to be connected or repaired substantially as
described.
