COMPLETE SPECIFICATION.
Improvements in and relating to the Sockets of Pipes for Sewerage
and other Purposes.
We, WILLIAM GOODMAN of Market Street, Swadlincote in the County of Derby,
Potter, and CHARLES RICHARDSON SOAR of Woodhouse Street, Swadlincote Road,
Woodville in the County of Derby aforesaid, 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 :-
The object of our invention is to effect certain improvements in and relating
to the sockets of earthernware pipes for sewerage and other purposes, to ensure a
perfect alignment of the pipes when laid and to prevent any lateral play."
In order that our invention may be the more readily understood we have caused to
he annexed to this specification two sheets of drawings the different figures upon
which will be hereinafter referred to :-
Figure 1 is a cross section through a spigot and socket joint upon line “a.” “ a.
of Figure 4 shewing one application of our invention.
"
Figure 2 is a cross section upon line b. b. of Figure 5 through a spigot and
socket joint shewing a second application of our invention.
Figure 3 is a cross section on line c. c. of Figure 6 through a spigot and socket
joint shewing a third application of our invention.
Figures 4, 5 and 6 are longitudinal sections on lines d. d., e. e., f. f. of
Figures 1, 2 and 3 respectively.
In carrying out the application of our invention illustrated on Figures 1 and 4
we form the bottom of the socket A either for part of its depth as shown on
Figure 4 or of its full depth internally of a flat ✓ shapo at the bottom, as shown
more clearly upon Figure 1, so that the spigot will naturally take its proper
alignment and position in the socket.
In the application of our invention shewn on Figures
and 5 the bottom of
the socket B is formed either for its full depth or only part of its depth as seen
upon Figure 5 of a semi-polygonal shape such as, and preferably, but not of
necessity, a hexagonal form."
In both the latter cases the grooves () may be formed if desired for the purpose
of allowing for the unequal contraction between the top and bottom parts which
would otherwise be experienced in such sockets.
In the application of our invention shewn upon Figures 3 and 6 the root or
shoulder D of the socket is made of any desired polygonal form to allow for the
variation of earthernware pipes from the true circle but at the same time to
ensure a good fit and obtain perfect alignment, the spigot being turned round
until the above conditions are ensured. The outside of this socket may be formed
if found more convenient of the same polygonal shapo as the inside as shewn upon
Figure 3.
The spaces F may in all cases be filled in with any kind of cement either plastic
or liquid.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-

page_text: sloping flat V shaped bed substantially as described and illustrated on Figures 1
and 3.
2. The improved socket for use in sanitary pipe joints having a bed for the
reception of the end of the spigot of a polygonal form substantially. as described
and illustrated on Figures 2 and 5.
3. The improved socket for use in sanitary pipe joints having a polygonal
shoulder or root D and substantially as described and illustrated on Figures 3 and 6.
Dated this 18th day of January 1897.
