COMPLETE SPECIFICATION.
Improvements in Causeway Channels, and, in Down Pipes and
Connections therefor and for Drains.
I, ALICE BIGWOOD, of Wood Place, Penn Fields, near Wolverhampton,
Staffordshire, Married, Woman, 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 reference firstly to improvements in what are known as cause-
way channels which are cast iron pipes of rectangular or other convenient form in
cross section sunk in foot paths or causeways for carrying water and drainage across
the same from down pipes or other pipes of buildings to the road, gutter, and this
invention has reference secondly to down pipes and connecting pipes for connecting
to the said causeway channels and to drains.
The objects of my invention are to prevent the causeway channel becoming
choked and to facilitate the connecting of a down pipe thereto or to a stink trap
and to facilitate the connection of a horizontal earthenware cast iron or other drain
pipe to the said causeway channels and to facilitate the fixing and removing of any
length of down pipe which may be rendered necessary.
I will describe my invention by referring to the accompanying drawing on
which
Figure 1 is a front elevation (partly in section) and Fig. 2 is a sectional side
elevation of a causeway channel and down pipe connection constructed in accordance
with this invention;
Fig. 3 is a plan of the causeway channel separately and
Fig. 4 is a plan of the down pipe and its connection, separately;
Fig. 5 is a front elevation and Fig 6 is a sectional elevation of part of the down
pipe shewing my improved, construction of joint;
Fig. 7 is a sectional elevation, Fig. 8 is a plan and Fig. 9 is an end view of
another form of my improved causeway gulley and its connection to a horizontal
earthenware cast iron or other drain pipe.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawing.
In order to connect, a down pipe a (see Figs. 1, 2, 3 and 4) to the causeway
channel I make a socket opening e, preferably of rectangular form, at the entrance
end of the causeway channel and projecting from the upper side thereof as shewn
in Figs. 1, 2 and 3. I also make a short connecting pipe D of cast iron or other
suitable material which at its lower end d' is rectangular or of other form to fit in
the socket on the causeway channel and has a shoulder d² a short distance
from its lower end which rests upon the top of the socket c. The down pipe a
enters the upper end d³ of this connecting pipe D and the latter is made of a
cylindrical or other shape corresponding with the down pipe a and of a sufficiently
large internal diameter or area to permit of the down pipe a being inserted if
necessary down to the bottom of the connecting pipe D so that if the down pipe
varies somewhat in length it is not necessary to cut it. The top of the
connecting pipe D is contracted to but just a little larger than the outside of the
down pipe a so as to maintain the down pipe central and effectually prevent any
dirt entering the connector D. It will be seen that no jointing material is used
in connecting the spigot end of the down pipe a to the socket connector D, as by
the contracted upper part d³ this is rendered unnecessary, and if either the
connecting pipe D or the causeway channel b should by any means become choked
then the water flowing out through the top of the connector D would at once shew
where the obstruction lay.

page_text: This construction of socket with the contracted upper end is also similarly,
and for the same purposes, applicable to the socket ends of down pipes as shewn
in Figs. 5 and 6.. When a flush of water takes place down the down pipe a the
water cannot escape through the narrow space between the contracted end d³ and
the spigot as this is prevented by the spigot passing down into the socket and by
the air rushing in through the said narrow space.
When connecting a horizontal round earthenware, cast iron or other drain pipe
to a causeway channel I make the causeway channel (see Figs. 7, 8 and 9) a
straight through rectangular pipe open at both ends and at the inlet end I form
the rectangular socket e to take the connecting pipe E which is of cast iron or
other suitable materials and at its outlet end has a rectangular spigot d¹ to fit in
the socket (similarly to the connecting pipe D) and at its inlet end ethe
connecting pipe E has an ordinary round or other shaped socket made of any
required diameter or area to take the spigot end of the earthenware, cast iron or
other drain pipe to which the causeway channel is required to be connected.
It will be seen that the connecting pipe E forms a very ready means of connecting
the round or other shaped drain pipe to the rectangular causeway channel b.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved causeway channel b made with the upwardly projecting inlet
socket c for the down pipe connection as hereinbefore described and illustrated by
Figures 1, 2 and 3 of the accompanying drawing.
2. The improved connecting pipe D for connecting a down pipe to a causeway
channel the said pipe D having its upper cylindrical or other shaped socket end
contracted as at d and its lower end made with a rectangular or other shaped
spigot d' and shoulder d' all for the purposes and substantially as herein before set
forth and shewn by Figures 1, 2 and 4 of the accompanying drawing.
3. The improved spigot and socket connecting pipe E having a round socket e¹
at one end to connect to a round drain pipe, and a rectangular spigot d' at
the other end to connect to the socket end of a causeway channel as hereinbefore
set forth and shewn by Figures 7, 8 and 9 of the accompanying drawing.
4. The improved form of socket for spigot and socket down pipes made with a
contracted top part das herein before described and shewn by Figures 5 and 6 of
the accompanying drawing for the purposes set forth.
5. In combination with the causeway channel having the inlet socket at the
top thereof the use of the down pipe connection D in the manner and for the
purpose hereinbefore set forth and shewn by Figures 1 and 2 of the accompanying
drawing.
"
6. In combination with the causeway channel 6 having the inlet socket c at one
end thereof the use of the round to rectangular connecting pipe E in the manner
and for the purpose herein before set forth and shewn by Figures 7 and 8 of the
accompanying drawing.
