Improvements in the Method of and Apparatus for Jointing Earthen-
ware to Metal and other Cases where there is a Beaded Pipe
End, Nozzle, or its equivalent to be Attached to a Pipe or the
like.
We EDWARD WILLIAM QUIRK of 33, Gainsborough Road, Liverpool in the
County of Lancaster Foreign Correspondent and ROBERT THOMAS BELLS of
42 Derby Street, Birkenhead in the County of Chester, Engineer do hereby
declare the nature of this invention to be as follows :-
This invention has for its object a method of and apparatus for jointing earthen-
ware to metal, and other cases where there is a beaded pipe end, nozzle, or its
equivalent to be attached to a pipe, or its equivalent. It is applicable especially
for attaching the flushing pipe to a water closet, soil pipes to water closets, flushing
or ventilating joints for water closets, or connecting "P" or "S" or other like
traps to lead or other metal pipes, connecting traps for sinks such as those used for
butlers' pantries, stoppers for bottles and jars for chemical or other
purposes, and
generally for use in any position where a glass, earthenware or other fictile or hard
structure has to be attached to a metal one.
Owing to the small flange or bead which is necessary for the joint to hold on to
the orifice of fictile or other hard or brittle ware it has hitherto been necessary to
make a soft joint which afterwards hardens, or a flexible joint such as an india-
rubber pipe, as other jointed devices at present known will not pass over the bead.
Now our invention is designed to form a metallic joint with packing which will
pass over this bead. On a metallic pipe we place a broad flange with a screwed
projecting rim sufficiently large in diameter to hold the aforesaid bead. The face
of this flange is preferably covered with an india-rubber washer let into the body
of the flange. A split flange with projecting rim and external screw thread is now
placed round the body, the thread of the flange fitting and being screwed into, the
screwed flange of the other part of the joint already described. Previous to
screwing however an india-rubber band or other soft material for making the joint
is placed inside the split flange. In order to enable the split flange to be more
easily screwed into the other and to be more manageable I place projecting pins on
one of the two halves fitting into the holes on the other, or in place of this the two
can dovetail or off set into each other in any desired manner. The rims of both
flanges can have milled edges, canted sides or other means whereby force can be
applied to them to screw them one into the other. By this means a thoroughly
satisfactory joint is secured without the rags and putty hitherto used for this
purpose.
It is obvious that other materials used for making a joint, such as red lead or
leather, can be used instead of the india-rubber. We prefer however the india-
rubber for most purposes.

Improvements in the Method of and Apparatus for Jointing Earthen-
ware to Metal and other Cases where there is a Beaded Pipe
End, Nozzle, or its equivalent to be Attached to a Pipe or the
like.
We, EDWARD WILLIAM QUIRK of 33 Gainsborough Road Liverpool, in the
County of Lancaster Foreign Correspondent and ROBERT THOMAS BELLS of
42 Derby Street, Birkenhead in the County of Chester, 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 :-
This invention has for its object a method of and apparatus for jointing earthen-
ware to metal, and other cases where there is a beaded pipe end, nozzle, or its
equivalent to be attached to a pipe, or its equivalent. It is applicable especially
for attaching the flushing pipe to a water closet, soil pipes to water closets, flushing
or ventilating joints for water closets, or connecting "P" or "S" or other like
traps to lead or other metal pipes, connecting traps for sinks such as those used for
butlers pantries, and generally for use in any position where a glass, earthenware
or other fictile or hard structure has to be attached to a metal one.
Owing to the small flange or bead which is necessary for the joint to hold on to
the orifice of fictile or other hard or brittle ware, it has hitherto been necessary to
make a soft joint which afterwards hardens, or a flexible joint such as an india-
rubber pipe, as other jointed devices at present known will not pass over the bead.
Now our invention is designed to form a metallic joint with packing which will
pass over this bead.
In the accompanying drawings:
Figure 1 is an elevation, partly in section, showing the method of jointing an
earthenware to a straight metal pipe ;
Figure 2, a perspective view of a portion of the split gland or ring;
Figure 3, an elevation partly in section of the method of jointing an earthenware
to a metal pipe bend; and
Figure 4, a plan of the split gland or ring of Figure 3.
On a metallic pipe (such as A or B) we form a flange a, and place over this
flange a screwed projecting ring C, sufficiently large in diameter to receive the
bead d of the earthenware pipe D. The face of the flange a is preferably covered
with an india rubber washer E against which the bead d abuts. A split gland or
flange F, with projecting rim and external screw thread, is now placed round the
body of the earthenware pipe D, the thread of the flange fitting and being screwed
into the screwed ring C. Previous to screwing, however, an india rubber band G.
or other soft material for making the joint is placed inside, between the bead and
the flange.
In order to enable the split flange F to be more easily screwed into the other
and to be more manageable, we place projecting pins. on one of the two halves
fitting into the holes on the other, or, in place of this, the two can dovetail or
offset into each other in any desired-manner. The rims of both flanges can have
milled edges, (as shown in Figure, 3) canted sides, slots G for wrenches (Figure 2)
or other means whereby force can be applied to them to screw them one into the
other. By this means, a thoroughly satisfactory joint is secured without the rags
and putty hitherto used for this purpose.
It is obvious that other materials used for making a joint, such as printer's
blankets, asbestos, or leather can be used instead of the india rubber; we prefer,
however, the india rubber for most purposes.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :-
1. The method of jointing earthenware to metal or other cases, where there is a
beaded pipe end, nozzle, or its equivalent to be attached to a pipe or the like,
which consists in forming, on the metallic pipe, a flange with a screwed projecting
rim, sufficiently large in diameter to hold or receive the bead, and in placing round
the beaded earthenware pipe end, or its equivalent, a split flange also with screwed
projecting rim, and finally in screwing the rim of one flange to the rim of the
other flange, whereby a tight joint between the earthenware and metal is
obtained.
2. A joint for connecting earthenware to metal in which there are two rings or
flanges, one passed round the flanged end of the metal pipe or stem, and the other
(a split one) round the beaded earthenware pipe end, nozzle or its equivalent, the
two rings or flanges being screwed together, whereby a tight connection between
the metal and earthenware is obtained without the use of cement substantially as
described.
3. In a metal and earthenware pipe joint, the combination, with the metal
ring C, of the ring F formed in two halves, and dovetailed or pinned together so
as to be easily separated to connect or disconnect the joint substantially as set
forth.
