1 JAMES GEORGE KILLEY of 5.1. Arabin Road Brockley S.E. Civil Engineer do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of pipes of earthen-
ware, or other material, in such a manner as to secure a watertight connection and a
continuity of the eveness of the invert in a more simple manner than that obtained
with the common socket pipe.
For this purpose I construct or form pipes with ends made to fit accurately one
against the other and having at a short distance from one end a projecting collar, and
I construct or form a band having a groove on its inner side and so constructed as
to fit accurately on to the ends of the pipes and against the projecting collar and
provided with one or more pour holes for cement or other material.
When the pipe first laid is ready to receive the band for the purpose of making
the joint, I fill up the lower half of the groove in the band with cement or other
material and slide the band on to the end of the pipe and against the projecting
collar the next pipe to be laid is then placed in the band and against the end of the
pipe first laid and the joint completed by pouring cement or other material through
the pour holes and so filling the upper half of the groove.
The band may be made in two pieces to suit various modifications as may be
desired.

page_text: 1, JAMES GEORGE KILLEY, of 51 Arabin Road Brockley, in the County of Surrey,
Civil 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:
My invention relates to improvements in the construction of pipes of earthenware,
glass, concrete, iron or other material and has for its object to socure a more water-
tight connection and a better continuity of the evenness of the invert than can be
obtained by the means usually adopted.
For this purpose I construct or form pipes with ends made to fit accurately one
against the other and having at a short distance from either or both ends a projecting
collar; and 1 employ a band or ring having a groove on its inner side, the said
band or ring being so constructed as to fit accurately on to the ends of the pipes
and against the projecting collar or collars and provided with one or more holes for
the introduction of cement or other material. The said band or ring may be made
in two pieces if desired.
In order that my said invention may be fully understood I will describe how the
same may be carried into practice by reference to the accompanying drawing, in
which
Figure 1 is a longitudinal section of two pipes connected together, and,
Figure 2 an end view of one of the said pipes shewing the jointing band or ring
in section.
Figures 3, 4, 5 and 6 are views illustrating modifications of my invention, and
hereinafter described.
Similar letters of reference indicate corresponding parts in all the figures.
a, a indicate portions of pipes to be jointed and b, b the collars formed on the
said pipes, e, e are the jointing bands or rings, and d, d the holes formed in the same
for the introduction of the cement or similar material.
As shewn in Figure 1 each pipe is provided with one collar only and the collared
end of the pipe a is arranged to abut against the plain end of the pipe a'. The
ring or band has two flanges e so that when the said band or ring is placed in
position a space f will be left around the abutting ends of the two pipes, as shewn in
Figures 1 and 2.
The method of forming the joint is as follows, that is to say, after the pipe a is
laid in position, a band or ring e, the lower half of which is filled with cement or
other suitable plastic material, is placed thereon so that one of its flanges e is in close
contact with the collar b. The plain end of the next pipe to be laid is then placed
in the band and against the end of the pipe a. The joint is then completed by
pouring cement or the like through the holes d, so that the space is completely
filled.
In the modification of my invention shewn in Figure 3, the collar c has only one

page_text: flange e, a ring y being employed in lieu of the second flange. Or, the said ring g
may be formed integral with the pipe a². In this case it will be understood that
each pipe is provided with a collar on both ends.
In the modification shewn in figure 4, each pipe is also provided with a collar bon
each end, which collars may, if desired, extend to the end of the pipe as indicated
by dotted lines in figure 4. In this modification the said collars are bevelled on
their peripheries and are adapted to fit into the flanges e of the ring or band c which
are correspondingly bevelled."
As shewn in figure 5, the pipes and ring or band are arranged substantially as
described with reference to figure 1, except, that the collar bis placed within the
groove of the ring or band. In this case it is necessary to make the said ring or
band in two parts adapted to be connected together, for instance, as shewn at h in
figure 6, to allow of the application of the ring or band over the collar.
Although I have described the collars b as extending quite around the pipes it is
to be understood that in all cases where the office of the said collar is simply to ensure
the proper placing of the ring or band, that a series of lugs may be substituted for
the said collar.
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. The improvement relating to earthenware and other pipes which consists in
forming collars or lugs upon one or both ends of the same and combining therewith
a ring or band in such a manner that a space is formed around the abutting ends of
the said pipes, substantially as, and for the purpose, described.
2. The manufacture and use of the improved pipes and the collars for jointing the
same substantially as described with reference to the accompanying drawing.
