COMPLETE SPECIFICATION.
Improvements in and relating to Sanitary Pipes.
I, CHARLES RICHARDSON SOAR of Woodhouse Street, Swadlincote Road,
Woodville in the County of Derby, 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 objects of my invention are to ensure perfect alignment of pipes when laid,
a perfectly tight joint, and, to enable the engineer or other person to see at a
glance when the pipes have been properly laid and butted up to each other.
In describing my invention reference will be had to the two sheets of drawings
forming part of this Specification each figure upon which is a vertical longitudinal
half section through a pipe joint, shewing an application of my invention.
In the form of my invention illustrated on Figure 1 the spigot and socket are
respectively roughened in the usual manner, by means of small annular recesses,
from A to B and C to D, upon each portion are fixed galamac or composition
rings E, E; F, F which are provided, as will be seen upon referring to the
drawing, with coarse threads engaging each other. The spigot being screwed into
the socket until tight up as shewn on the drawing, cement is then poured into the
annular recess G through the orifice H. Ribs I may be formed on the pipe partly
for convenience in screwing and unscrewing and partly so that by the ribs on one
pipe being in line with those of the next the person laying then may know that
they are screwed home, and, partly for strength. Upon Figure 2 galamac or
composition threaded rings J, K, are shewn fixed on the spigot and socket
respectively at the root thereof, but instead of the arrangement shewn on Figure 1,
I fix an earthenware or other flange L to the spigot by means of galamac or
composition M and splay the ends of the flange and socket on the outside where
they meet, and pass round this portion a hemp, rubber or other suitable band N
while cement is poured into the annular space O through the orifice P. Ribs I
may also be used in this case as described in reference to Figure 1.
Figure 3 illustrates an application of my invention in which a galamac or
composition flanged ring Q is fixed on the end of the spigot and engages a galamac
ring R fixed in the root of the socket, a slight space being left between the flange
and the end of the ring R; an earthenware flange or ring S is fixed to the spigot
of the pipe by means of galamac or composition T the end of the socket and face
of the flange where they meet being recessed as shewn at W and X. Cement is
poured into the annular space U through the orifice V.
Upon Figure 4 an inclined centreing piece Y of galamac, composition or
earthenware is shewn, up which the spigot passes until it butts up to the socket, a
galamac or composition flange Z is shewn fixed to the spigot and is splayed on the
side next the end of the socket to receive the hemp, rubber or other ring 1 while
cement is poured into the annular space 2 as already described in reference to
Figures 1, 2 and 3.
Figure 5 shews an opening 3 in the top of the socket end of a pipe, over the
root of the said socket, so that the engineer or superindant may inspect each
joint and see whether it has been properly butted up or not, this opening also
serves for the purpose of pouring in liquid cement. Upon this figure is also shewn
an annular cutting or mark 4 which should be at a given distance from the end of
the socket when the spigot is properly butted up, thus another security is provided
for that purpose.

page_text: Figure 6 illustrates a tapered earthenware self centreing ring 5 fixed on the
spigot of the pipe by means of galamne or composition 6, cement being either
poured into the annular recess 7 ns described in reference to the previous figures or
it may be partly packed in from the end before the spigot is pushed home.
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 improved sanitary pipe joint having threaded galamac or composition
rings on the spigot and socket respectively adapted to engage each other and leave
a space G for the reception of liquid cement to be poured in through orifice H
substantially as herein described and illustrated on Figure 1.
2. The improved sanitary pipe joint having threaded galamac or compusition
rings J, K in the socket and on the spigot respectively and adapted to engage each
other, an earthenware ring or flange L fixed to the spigot end of the pipe by
means of galamac M leaving a space O between it and rings J, K the unds of
socket and flange being splayed or bevilled for the reception of hemp or other
cord or hand N substantially as described herein and illustrated on Figure 2.
3. The longitudinal external ribs substantially as and for the purposes
described and illustrated.
4. The improved sanitary pipe joint having galamae or composition ring R fixed
in the root of the socket in combination with and engaging a galanne or
composition flanged ring Q fixed on the spigot, an earthenware ring or flange S
fixed to the pipe by means of galamac T leaving a space U for liquid cement; the
faces of the flange or ring S being recessed as shewn where they meet substantially
as described herein and as illustrated on Figure 3.
5. In a sanitary pipe joint the employment of a tapering self centreing piece Y
in combination with a splayed or bevilled galamne or composition flange or ring
and hemp or other cord or band 1 substantially as described herein and illustrated
on Figure 4.
6. In a socketted sanitary pipe joint the inspection orifice 3 and a gauging
mark 4 substantially as described herein and illustrated on Figure 5.
7. In a socketted sanitary pipe joint the employment of a tapering earthenware
self centreing ring 5 fixed on the spigot end of the pipe by means of galamac or
composition 6 substantially as described herein and illustrated on Figure 6.
