PROVISIONAL SPECIFICATION.
Improved Connection for Water Closet Joints or Flange Pipes of
any description.
1 HENRY JOHNSTON 138 Conway Street Birkenhead, Cheshire Brassfounder
do hereby declare the nature of this invention to be as follows:-
To provide a collar or flange on the back of male ring in a joint, which will
obviate the necessity of using a split dowelled ring as at present.
The connection of joint is made in the usual way, viz., by screwing two rings,
male and female, together with tail piece; or, tail and ring of one half may be
cast in one piece if desired.
The inside of female ring is made to pass over flange of joint.
The male ring, instead of being split and dowelled, as at present in use, is fitted
with three, more or less, parts of a ring, made to pull back, or push into position
as required.
When in position they form a smaller ring, or flange at back of closet or pipe
flange.
These parts of a ring are fastened at one end, on back of male ring, by means of
a screw or rivet; and work as on a pivot. The other end of parts is slotted up to
centre; and when in right position is held in its place by a second screw,
countersunk into the part, making it impossible for the part to move back.
When wanted off, the parts of ring are turned back, giving clearance room for
closet or pipe flange to be passed out.
When replaced they form a strong flange or collar at back of closet or pipe
flange.
The two rings, male and female, when screwed home, together with rubber or
insertion, form a perfectly tight joint.

Improved Connection for Water Closet Joints or Flange Pipes of
any description.
I, HENRY JOHNSTON, Brassfounder, of 138 Conway Street, Birkenhead in the
County of Chester, 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 :—-
This invention relates to pipe couplings, and more especially to couplings
employed for connecting pipes to water closet pans, wash basins and the like
earthenware vessels.
Heretofore, the method of coupling a pipe to an earthenware or glass vessel
consists either in making a putty, red lead or cement joint, or, in employing a screw
coupling in which the male portion is split to pass over the flange on the earthen-
ware or glass vessel; but in each case it is exceedingly difficult to uncouple the
pipe for inspection etc., and the object of my invention is to provide a coupling
which may be easily detached even by an unskilled person.

page_text: I effect this by using the ordinary screw coupling but I dispense with the flange
and substitute therefor three or more pivoted segmental pieces, as described more
particularly hereinafter.
I have illustrated my invention by the accompanying drawings in which, Figs. I,
II, III and IV represent a coupling used to connect a soil pipe to a water closet
pan, and Figs. V and VI a modified form of coupling for an analogous purpose.
Throughout the drawings similar parts are indicated by the same reference
figures.
Referring first to Figs. I to IV, the coupling consists of the usual male and
female portions 1 and 2 of a screw coupling, but in which three pivoted segments 3
are substituted for the ordinary flange of the male portion 1. These segments 3
are attached to the male portion of the coupling by the pivot screws 4 and the
locking screws 5. In Figs. I, II and III (which are respectively a sectional
elevation, an outside elevation and a plan), the segments are shown closed and it
will be seen that they form a three part ring which engages with the shoulder 6
on the nozzle 7 of the water closet pan. When the male portion 1 is put in
position on 7, it is of course necessary that the segments should pass over the
flange 6, and they are therefore opened out or turned back to clear the flange
as shown in Fig. IV; when the part 1 is in position the segments are turned in
again and secured by the locking screws 5 which enter the slots 8. The joint is
now made by screwing up the female part 2 of the coupling, the fixed flange 9 of
which bears against the flange 10 of the pipe 11. An interposed washer 12 of
rubber or other suitable material may be interposed as shown in Fig. I.
It sometimes happens that neither the male or female portion of the coupling
can be placed in position without having to pass over a bead or flange, as for
example, in the case illustrated in Figs. V and VI (which are views analogous to
Figs. I and II) in which the pipe 111 has a supporting flange 13 which prevents
the part 2 being put in position from below. In such cases I fit the segments 3 to
both the male and female parts of the coupling as shown in Figs. V and VI.
I have shown three segmental pieces fitted to the couplings illustrated in the
drawings, but it is evident that the number may be varied; I have found however
that it is not desirable to fit less than three. I have also shown the segmental
pieces applied to a screw coupling, but it is to be understood that they are equally
applicable to couplings in which the parts are secured together by bolts, etc.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, declare that
what I claim is ;-
1. The improvement in pipe couplings which consists in forming the portion of
the coupling which engages with the flange or bead of the pipe, of pivoted
segmental pieces adapted when opened out to clear the said flange or bead;
substantially as described and illustrated.
2. In combination with the male and female portions of a screw coupling, the
segmental pieces pivoting about the screws 4 and locked by the screws 5;
substantially as and for the purpose described.
3. The improved coupling substantially as described and illustrated in Figs. I
to IV.
4. The improved coupling substantially as described and illustrated in Figs. V
and VI.
