WALTER BOSWELL 29 North Street Manchester Square Builder THOMAS
MARCUS HOUGHTON 58 Wimpole Street W. Surveyor do hereby declare the
nature of this invention to be as follows:-
This invention is for the purpose of more readily forming the joints between
vertical soil or other pipes and horizontal or drain pipes, for disconnecting for
testing or other purposes and in such a manner as to allow for the expansion or
contraction of the metal, the settlement of the building or subsidence of the
ground without breaking or disturbing the joint and which is effected in the
following manner.
A length of metal tube is slipped over the end of the lead soil or other pipe
which latter is tafted and soldered or fixed to same, another length of similar pipe
is screwed to same the base being prepared with a flange to rest in the socket of
drain pipe. Teats or other suitable projections or indentations are formed on the
bottom length of tube to form a grip for leverage or spanner.
The bottom length of tube being screwed down takes a bearing in the socket of
the drain pipe the joint being formed with a packing of tow asbestos or other
suitable materials, on screwing up the outer or lower length of tube the lower end
of the upper length of tube will be exposed and a cap may be screwed on when
As an alternative
it is required to charge the soil or other pipe for testing purposes.
to the foregoing and for the purpose of counteracting the effect of subsidence of
foundations or ground and the expansion or contraction of materials employed, the
lower length of tube instead of being screwed to the upper length will be made to
slide on same, with a flanged adjustable packed air and water tight joint, the joint
of the lower tube with the drain pipe will be flanged and bolted together with a
suitable packing and when the drain is of earthenware the face of the flange of
same will be ground or faced with composition as Stanford's joints or other suitable
material.
A cap may be attached to the end or inserted in the joint when it is desired to
charge the vertical pipe with water for testing purposes.
A stop cock will be fixed in the cap for the purpose of letting off the water
gradually.
The bend changing the direction from horizontal to vertical may be either of
metal or stoneware and when of the first named material the flanged bolted joint
may be made at the lower end of bend with horizontal drain.

COMPLETE SPECIFICATION.
A New or Improved Pipe Connector and Stopper.
We, WALTER BOSWELL, of 29 North Street, Manchester Square, in the
County of London, Builder, and THOMAS MARCUS HOUGHTON, of 58 Wimpole
Street, also in the County of London, Surveyor, 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 object of this invention is to more readily form the joints between vertical
soil or other pipes and horizontal or drain pipes. Joints formed in accordance with
this invention can be readily disconnected when it is desired to test the pipes or for

page_text: other purposes and can be as easily connected up again. In a modified form of our
invention, we provide for the expansion or contraction of the metal pipes, the
settlement of the building, or the subsidence of the ground without breaking or
disturbing the joint.
In the accompanying drawings Figure 1 shows, in sectional elevation, a simple
form of our pipe joint, and Figure 2 shews a sectional elevation of a modification.
Referring first to Figure 1, a length of strong metal tube A, preferably brass, is
slipped over the end of the lead, soil, or other pipe B, so that its end is close down
to the end of the pipe B. The bottom of the said pipe B may be tafted, that is
turned outwards at right angles or thereabouts, so as to form a flange on which
the bottom of the outer brass or other tube A. rests, and the two soldered together
at the top and bottom of the said tube A, or they may be otherwise rigidly affixed
to each other.
The tube A is screw-threaded and screws into an outer tube C of similar
material having a corresponding female thread. The base of the outer tube C is
flanged at D which said Hange rests in the socket F of the drain pipe E. Teats or
other suitable projections or indentations may be formed on the outside of the tube C
to form a grip for a lever or spanner.
When the outer tube C is screwed down on the tube A, the flange D takes a
bearing in the socket F of the drain pipe E, the joint being formed with a
leather ring, washer, or with a packing of tow, asbestos, or other suitable
material G, the socket F being afterwards filled in with cement or other suitable
material K.
To disconnect the joint, the cement or other material K is removed, and the
outer tube C is screwed up over the tube A and pipe B. When screwed up clear
of the drain pipe socket, a suitable metal plate may be bolted to the flange D,
which is provided with bolt holes for the purpose, a washer or the like being inter-
posed so as to make a water-tight joint. If desired the metal plate may be
provided with a stop cock. The stand pipes of which the lead pipe B forms a part,
may now be tested in the ordinary manner and the water run off through the stop
cock after the testing. To connect the joint again the metal plate is removed, the
tube C screwed down till the flange D presses tightly on the washer or packing G
in the socket F of the drain pipe, when cement K may be filled in as required.
In the modification shewn in Figure 2, the outer tube C slides over the brass or
other tube A secured to the vertical pipe B. On the upper end of the outer tube C
is a flange L over which is bolted an annular cover M. Between the flange and
cover is a packing of tow, asbestos, or other suitable material H, which is
laterally distended and caused to bear against the brass or other tube A, as the
bolts are tightened up, thus forming an adjustable air and water tight packing
between the tubes A and C.
The flange D on the lower end of the tube C may rest in the socket F of the
drain pipe E as in Figure 1, or the drain or other pipe E may be formed with a
flange J and the joint formed by bolting the flanges D and J together by the bolts N
passing through bolt holes made for the purpose in both flanges, a leather ring or
other washer being interposed between the flanges. This method of attaching the
outer tube C to the drain or other pipe E may be adopted with the screwed form
of our invention shewn in Figure 1.
By forming the joint so that the tube C slides over the tube A. as in Figure 2 it
is obvious that the effects of the expansion or contraction of the material employed
is provided for and also that any subsidence of the building or of the ground will
not result in a fracture of the joint, but that the tubes A and C will rise or fall and
will thus counteract such subsidence, contraction, or expansion. When the drain or
other pipe E is of earthenware, the upper face of the flange J will be ground or
faced with a composition such as Stanford's composition or other suitable material.
For testing or other purposes the bolts N are unscrewed, the outer tube C raised,
and a metal plate bolted therein in the manner hereinbefore described with reference
to Figure 1.

page_text: Although we have described and shewn our invention as applied to connect a
soil pipe with a drain pipe, we wish it to be understood that this method of
forming the joint may be used in any and every case where a vertical pipe is
connected to a horizontal or curved pipe. For instance our invention may be
applied to a closet trap, the pedestal of the closet being bolted down to a flange
on the upper end of the trap, a washer being placed between the pedestal and
flange, or the pedestal may be securely held in proper position by means of two
or more clips bolted to the floor or other base on which the closet is standing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1) The method of connecting pipes consisting of a brass or other tube A
firmly secured to the vertical lead pipe B, the said tube A being externally
screw-threaded and engaging with a female thread on an outer tube which
latter is provided with a flange D bolted to a corresponding flange J on the
horizontal or curved pipe E with a washer G between the flanges, or the flange D
rests on a washer G in a socket F in the pipe E, the socket being afterwards
filled up with cement or other similar material K substantially as and for the
purpose hereinbefore set forth and illustrated in the accompanying drawings.
(2) The modified form of our invention described with reference to Figure 2
wherein the outer tube C slides over the tube A, an adjustable water and air
tight joint between the two tubes A and C being produced by the packing H,
flange L cover M and bolts; the tube C and horizontal or curved pipe E being
connected together by the bolted flanges shewn in Figure 2 or by the socket joint
shewn in Figure 1 substantially as and for the purpose hereinbefore set forth.
(3) Our improved pipe connector and stopper substantially as described.
