COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Repairing Gas, Water,
and other Pipes and Mains.
I, ALFRED EARNEST BARNETT, Military Gas Works, Fermoy, County Cork,
Ireland, Manager, 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:―
My invention relates to improvements in the method of and means for repairing
gas, water and other pipes and mains, and has for its object to enable the repairs
to be performed in a quicker, simpler and more efficient manner than is possible
by the present method which consists in putting in a new length of pipe with a
double collar. It is adapted for use with water and gas mains and is applicable
to any analogous purpose. In carrying my invention into effect I proceed in or
in about the following manner, making reference to the accompanying sheet of
drawings in which
Fig. 1 is a side view, Fig. 2 a cross section and Fig. 3 a plan of my appliance
for facilitating the carrying out of repairs as above referred to.
Fig. 4 is a cross section of a modification for use when branch pipes are used.
Similar letters denote similar parts wherever occurring.
provide a long socket consisting of an upper part a and a lower part b, each
portion having flanges c, the upper flange having a ridge d on its lower face to fit
into a corresponding groove e in the upper face of the lower flange. The ridge
and groove
d and e have preferably return ends as shown in the case of e at f
(Fig. 3). Webs g may be provided at intervals to strengthen the flanges. Pro-
vision is made for bolts h by which a and b can be held together. Each end of a
and bis recessed out at i. Fig. 4 is a section showing how my invention may
be applied when a branch is required. In this case the branch socket j (which
may be made a part of, or separate from a or b) projects inside a and b as at k.
In use the damaged part is cleaned off and a and b of sufficient length placed
round the part of the pipe 7 to be repaired. The groove e is then filled with strip
lead or with rubber yarn, rope, milf board or other suitable substance. The two
part a and b are then bolted together and the joint at each end run "in the
usual manner, When the branch socket is used, a hole is made in the pipe and a
and b put on so that k enters the hole.
I do not confine myself to the precise shape configuration, relative proportions
or disposition of parts as shown in the drawings or referred to in the above Speci-
fication as any or all of them may be considerably varied without departing from
the spirit of my invention.
Having now particularly described and ascertained the nature of my said
irvention and in what manner the same is to be performed, I declare that what
I claim is:-
1. For use in repairing pipes and mains of all kinds, a socket or collar made in
halves with a flange at each side of each half. the flanges of one half having proiections

page_text: or ridges (preferably with return ends) destined to fit into corresponding grooves
provided in the opposing flanges of the other half of the socket, the dividing line
between the two halves being in the plane of the axis of the pipe under repair,
the said halves being held together by bolts and each end being provided with
annular recesses surrounding the pipe, the whole substantially as described in the
above Specification and exemplified in the accompanying drawings.
2. Providing the upper or lower half or both the halves of the socket. referred to
in the above Claim 1 with a branch socket or with branch sockets formed with or
separately from the half sockets above referred to, the said branch sockets having
projecting ends, to enter holes existing or provided for them in the pipe under
repair, the whole substantially as described in the above Specification and exempli-
fied in the accompanying drawings.
3. The improved method of and means for repairing pipes of all kinds, the said
method and means being provided for and operating substantially as described in
the above Specification and exemplified in the accompanying drawings.
Dated this 8th day of September 1897.
