Improvements in Coupling or Connecting Metal Pipes to Spigot
Orifloes of Earthenware Sanitary Vessels.
I GEORGE JENNINGS of Palace Wharf Stangate London S.E. Sanitary 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 thereof that is to say :-
This invention relates to improvements in coupling or connecting metal pipes to
spigot orifices of earthenware sanitary vessels and has for its object to provide an
elastic or shifting water tight union joint between the said pipe and spigot orifice.
For this purpose the spigot orifice is furnished with two half metal rings connected by
two screwed bolts to a metal disc or flange surrounding one end of the metal pipe.
The said disc or flange is recessed on its upper surface to receive an india-rubber or
other elastic ring through which is passed the end of the aforesaid pipe, and the upper
surface of which ring bears against the lower end of the spigot orifice upon tighten-
ing up the screwed bolts whereby an air-tight joint is provided between the pipe
and the spigot-orifice. The two half rings are tightened around the spigot-orifice by
means of two screws screwing into lugs formed on each side of the aforesaid half
rings. By means of this improved coupling the pipe is capable of longitudinal
movement therein whilst at the same time a perfectly air-tight joint is ensured.
a is the
And in order that my said invention may be more fully understood I will proceed
to describe the same with reference to the accompanying sheet of drawings in which-

metal pipe to the spigot-orifice of an earthenware basin or other sanitary vessel and

metal pipe and 6 the spigot-orifice formed on the bottom of a basin or other earthen-
ware vessel 61. c, c are two metal half rings which are secured or tightened around
the spigot-orifice by means of screws d screwing into lugs c¹ formed on each side
of the half rings c. e is the metal disc or flange surrounding the end of the pipe a
and through which passes two bolts f which are screwed into the two half rings c.
g is the elastic ring through which is passed the end of the pipe a and which rests
in a recess e¹ formed in the disc or flange e. As the bolts are tightened up they
jam the ring g between the disc or flange e and the bottom of the spigot-orifice b
thereby tightening the ring g around the pipe a and ensuring a perfectly tight joint.
As will be seen my improved joint permits of a radial and lateral as well as a
longitudinal movement or shifting of the pipe therein whilst ensuring a perfectly
tight closure.
Having now described and ascertained the nature of my said invention and
explained the manner of carrying the same into practical effect I would have it
understood that what I claim is.
The improvements in coupling or connecting metal pipes to spigot orifices of
earthenware sanitary vessels substantially as described and shown and for the purpose
specified.
