PROVISIONAL SPECIFICATION.
An Improvement in Pipes or Channels for Drains and Sewers, and
in the Jointing of same.
1, JOHN LEEMING, Architect, of Victoria House, 117 Victoria Street,.
Westminster in the County of Middlesex do hereby declare the nature of this
invention to be as follows:-
My invention relates to pipes or channels used for drainage and the like and.
comprises the improvements hereinafter described :-
First. The invention consists in forming the body of the pipe so that a channel,
groove or gutter may be obtained in the centre of the lower inside portion of the
pipe.
Second. The invention further consists in forming the lower outside portion of
the pipe so that a firm base may be obtained. This is accomplished by spreading
out the base of the pipe, either by means of lugs or prongs, or by any other
suitable projections.
Third. As regards the jointing of the pipes; the invention further consists in
forming a channel or groove at the butt end of the pipe and in making at the
corresponding or flange end of the pipe the following provisions :-(a) The lower
half of the pipe is extended beyond the upper portion so as to cover the channel
at the butt end of the adjoining pipe. This lower half is also to have a channel
or groove (with or without continuous lugs or prongs) corresponding to the
channel or groove at the butt end of the adjoining pipe, so that when liquid cement
or other suitable jointing material is poured in, this portion of the joint may easily
be made watertight and the pipes firmly secured together. (6) The upper half
of the pipe is also to be formed with a channel or groove as lastly described,
except that the said channel or groove is to be only one-half the size or extent of
the lower channel or groove, so as to enable this part of the joint to be exposed
to view. The jointing hereinbefore described may also be applied to circular drain.
pipes, either in whole or in part.

I, JOHN LEEMING, Architect, of Victoria House, 117 Victoria Street,.
Westminster, in the County of Middlesex 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 :---
My invention relates to pipes or channels used for drainage and the like and
comprises the improvements hereinafter described :-
First. The invention consists in forming the body of the pipe so that a channel,
groove or gutter may be obtained in the centre of the lower inside portion of the
pipe.

page_text: Second. The invention further consists in forming the lower outside portion of
the pipe so that a firm base may be obtained. This is accomplished by spreading
out the base of the pipe, either by means of lugs or prongs or by any other suitable
projections.
Third. As regards the jointing of the pipes; the invention further consists in
forming a channel or groove at the butt end of the pipe and in making at the
corresponding or flange end of the pipe the following provisions. The lower half
of the pipe is extended beyond the upper portion so as to cover the channel at the
butt end of the adjoining pipe. This lower half is also to have a channel or groove
(with or without continuous lugs or prongs) corresponding to the channel or groove
at the butt end of the adjoining pipe, so that when liquid cement or other suitable
jointing material is poured in this portion of the joint may easily be made water-
tight and the pipes firmly secured together. A rebate or lip is also formed on
this lower half of the pipe to obtain true alignment and to enable the pipe ends
to fit together; this rebate or lip is shown on the drawing hereinafter referred to
and thereon marked H. The upper half of the pipe is also to be formed with a
channel or groove as before described to lower half of pipe, except that the said
channel or groove is to be only two-thirds the size or extent of the lower channel
or groove, so as to enable this part of the joint to be exposed to view and to be
readily filled and pointed with cement or other suitable jointing material. The
jointing hereinbefore described may also be applied to circular drain pipes, either
in whole or in part.
Referring to the accompanying drawing :-
Figure 1 is a plan. Figure 2 is an elevation of the butt end. Figure 3 is an
elevation of the flange end. Figure 4 is a section of both butt and flange ends
and Figure 5 is a front elevation of the pipe or channel referred to.
A is the body portion of the pipe. B is the channel, groove, or gutter. C is
the lug or prong formed on each side of the pipe. D is the channel or groove at
the butt end of the pipe and E the corresponding channel or groove at the flange
end of the pipe. F is the extension to the lower half of the pipe. G and g the
points at which liquid cement may be poured in. H is the rebate or lip formed
on the lower half of the pipe to obtain true alignment, the corresponding rebate or
lip (h) to upper half of pipe having less projection than H so as to enable the
pipe ends to fit together.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. A pipe for drainage and the like, having a channel, groove, or gutter in the
centre of the lower inside portion thereof, and with lugs, prongs or other projections
at the base, substantially as described.
2nd. A pipe for drainage and the like, having provision for joints with channels
or grooves, and with rebate or lip for true alignment, substantially as and for the
purposes specified.
