PROVISIONAL SPECIFICATION.
Improvements in Joints for Sewer and other Pipes.
I, TOM WILKINSON, of Ashleigh, New Malden, in the County of Surrey,
Contractor, do hereby declare the nature of this invention to be as follows:-
My invention relates to a cheap and simple method of soundly jointing together
lengths of earthenware, ceramic, cement, concrete and other pipes, such as are
employed for sewers, drains and like purposes. I provide in the face at each end
of a pipe-length a groove, such that when two pipe lengths are brought together
face to face their grooves coincide. Into these grooves, partly in each, I fix with
any suitable cement a hoop of iron or other metal which is bent round into a ring
form completely covering such space as there may be between the ends of the
pipe lengths, and preventing any leakage of fluid.
A convenient way of making this joint is to bed the hoop with cement in the
groove of the one pipe with about half its width projecting, and then, having filled
the groove of the other pipe with cement, to press the two pipes together thus
forcing the projecting half of the hoop into the cement of the other groove.
The hoop may be corrugated, and two or more concentric hoops may be employed,
these being rivetted or otherwise fastened together or inserted separately in the
grooves.
In some cases, I make a groove in the end of the one pipe only, the hoop being
fixed on the outside of the other pipe at its end and projecting therefrom so as to
enter the groove.
When the joint is made in this way, I prefer to make the pipe
which has the groove with a faucet end, which encloses the end of the other pipe as
a spigot.
Dated this 9th day of January 1892.

COMPLETE SPECIFICATION.
Improvements in Joints for Sewer and other Pipes.
1, TOM WILKINSON, of Ashleigh, New Malden, in the County of Surrey,
Contractor, 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 a chap and simple method of soundly jointing together
lengths of earthenware, ceramic, cement and other pipes, such as are employed for
sewers drains and like purposes.
Fig. 1 of the accompanying drawings is a part longitudinal section of two pipe
lengths jointed together according to my invention. I provide in the face at each
end of a pipe length a groove G such that when two pipe lengths are brought
together face to face their grooves coincide. Into these grooves, partly in each, I
fix with any suitable cement a hoop H of iron or other metal which is bent round
into a ring form thus completely covering such space as there may be between the
ends of the pipe lengths, and preventing any leakage of fluid.
A convenient way of making this joint is to bed the hoop H with cement in the
groove of the one pipe with about half its width projecting, and then, having filled
the groove of the other pipe with cement, to press the two pipes together, thus
forcing the projecting half of the hoop into the cement of the other groove. The
hoop may be corrugated, and two or more concentric hoops may be employed,
[P27

page_text: these being rivetted or otherwise fastened together, as shewn in Fig. 2, or inserted
separately in the grooves. In some cases, I make a groove in the end of the one
pipe only, the hoop being fixed on the outside of the other pipe at its end and
projecting therefrom so as to enter the groove. When the joint is made in this
way I prefer to make the pipe which has the groove with a faucet end as shewn
in Fig. 3 which encloses the end of the other pipe as a spigot.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Joints for sewer or other pipes made by bedding hoops in cement in grooves
formed in the ends of the pipes, substantially as described.
