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,
and a perfectly tight joint.
In describing my invention reference will be had to the sheets of drawings
forming part of this specification upon which :-
Figure 1 is a vertical longitudinal half section through
application of my invention.
a pipe joint shewing an
Figure 2 is a similar view shewing another application of my invention.
Figure 3 shews a third application of my invention.
Figures 4 and 44 shew a fourth application of my invention.
Figure 5 shews a fifth application thereof.
Figure 6 shews a sixth application thereof.
Figure 7 is a cross section through a spigot and socket shewing a seventh
application of my invention.
Figure 8 is a vertical cross section through a spigot and socket joint shewing
an eighth application of my invention, and Figure 9 is a similar view as the last,
shewing a ninth application of my invention.
The substance hereinafter termed "galamac" is composed of varying proportions
of gas-tar, sulphur, sand or fine lime dust, boiled together with a little pitch
added.
In carrying out the application of my invention illustrated on Figure 11 fix on
the end of the spigot A an annular ring B of gaiamac or the like projecting
outwardly so as to cover a galanac ring fixed in the shoulder of the socket, the
meeting faces of the two rings being formed sloping or tapered as shewn. It will be
seen that the socket has a double shoulder, the outer shoulder being provided with an
internal galawac ring D which is tapered and arranged to engage with a galamac
ring E fixed to a projecting shaped earthenware ring or gland which is in
turn fixed on the spigot A by means of galamac or the like. The projecting flange
or the annular ring F butts up to the outer shoulder on the socket and covers the
joint between the two galamac rings E and D. A hole G is formed in the socket for
pouring in liquid cement.
in the application of my invention illustrated on Figure 2 the socket is again
formed with a double shoulder, the inner one being tapered and provided with a
galanac ring C, engaging a galamac ring B' similar to those illustrated on Figure 1;
plastic cement is placed in the space H and the gland I is screwed home until the
plastic cement oozes through the joints, threaded galamac rings J and K being fixed
on the gland and shoulder of the socket respectively.
In the application of my invention illustrated on Figure 3 a double shouldered socket
is again employed with the tapered portion L between the two, leaving a space M in
which plastic cement is placed, the gland N being pushed up until the cement oozes
through the joints; the whole when set being firmly secured together by means of the
cement in conjunction with the roughened internal surfaces of the joint.
Figure 4 shews a single shouldered socket with space O for plastic cement,

page_text: the outer end of the socket being tapered as at P internally to receive the tapered
portion of the gland Q. Figure 44 shews the end of the socket. rounded internally
instead of being splayed, in this case the face of the gland would be formed concave.
Figure 5 shews a double shouldered socket, the internal portion of the outer end
being recessed or formed as shewn at R for the reception of the coment, a gland may
be used in connection with this as described in relation to Figure 4, if desired.
In the application of my invention illustrated on Figure 6 a double shouldered
socket is employed leaving a space S in which is placed plastic cement, a galamac
ring Theing fixed on the spigot to receive the gland U also fixed on a galamac
ring V, the meeting faces of the gland and socket being provided with threaded
galamac rings W and X respectively.
Figure 7 shews an ordinary spigot and socket joint except that in the bottom
of the socket are formed a number of longitudinal ribs Y of a wedge or other
suitable shape. The spigot being placed on these ribs ensures the pipe being placed
centrally and in perfect alignment, the plastic cement being placed between them in
the usual manner. It will thus be seen that the spigot rests upon the points of the
ribs but at the same time has cement underneath it as well as all round it.
In the application of my invention illustrated on Figure 8 the socket is formed with
a flat bottom Z internally to form a centreing piece and has also a hollow 1 formed on
the underside to lighten the clay of which it is formed and form a bed for laying the
pipes. The self centreing piece Z may if desired be carried up to the dotted line 4
and be partly hollowed out for the reception of the spigot.
Figure 9 shews a similar application of my invention to that on Figure 8 except
that the bottom of the socket internally is formed rounded as at Z' and on the outside
has longitudinal recesses as at 2 to form a bed when laying same. The dotted line 5
shews how a groove or grooves may be cut or formed in the centreing pieces Z or Z¹
if desired for the reception of cement.
In the two last applications of my invention a longitudinal section of them is not
shewn but the socket would be formed with splayed, rounded or stepped enls to
engage glands carrying spigots correspondingly formed if desired.
For the sake of convenience the glands which have not threaded galamac rings
fixed thereon may be formed in halves if desired.
In reference to the centreing pieces Z and Z' on Figures 8 and 9 these may if
desired be formed in cement of any suitable form and fixed to ordinary socketted
pipes.
A distinct advantage is gained by using a gland inasmuch as the cement may be
forced home and into all the crevices of the joint much better than is the case where a
trowel or the like is employed for the purpose.
In reference to the composition "galaniac" herein frequently mentioned, it will be
understood that I may use any composition or substance instead of same that is equally
suitable, without departing from the spirit of my invention.
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 joint in sanitary pipes consisting of a double shouldered socket
carrying tapered galamac rings C and D adapted to engage correspondingly formed
rings B and E the latter being fixed on an shaped earthenware gland or flange F
fixed to the spigot A, a space 3 being left between socket and spigot for pouring in
liquid cement through the hole G, substantially as described and illustrated.
2. The improved joint in sanitary pipes consisting of a double shouldered socket
carrying a tapered galamac ring and a threaded galamac ring K, the former being
adapted to engage a similarly shaped ring B on the spigot and the latter being
adapted to engage a correspondingly threaded galamac ring J on the earthenware
gland I, space H being left for plastic cement, substantially as described and
illustrated.

page_text: 3. The improved sanitary pipe joint illustrated on Figures 3, 4, 4 and 5 having
spaces M, O, and O' for plastic cement, in combination with glands such as N and Q
the meeting ends of the sockets and glands being of any suitable shape as shewn.
4. The improved joint in sanitary pipes illustrated on Figure 6 consisting of a
double shouldered socket carrying a threaded galamac ring X adapted to engage a
correspondingly threaded ring W fixed to a gland U in turn secured to a galamao
ring and adapted to slide on the galamac ring T fixed to the spigot of the pipe, a
space S being provided for plastic cement, substantially as described and illustrated.
5. The improved joint for sanitary pipes illustrated on Figure 7 the socket having
longitudinal ribs or teeth Y of either the full depth or part of the depth of the socket
to form a means of ensuring the pipe being placed centrally of the one next to it.
6. The improved joint in sanitary pipes illustrated on Figures 8 and 9 having
self centreing pieces Z or Z' and undersurfaces such as 1 or 2 for bedding, and
securing perfect alignment with the modifications suggested by dotted lines 4 and 5,
substantially as described and illustrated.
