INVOVIDIONAL
Improvements in Drain and other Pipes and in the Means and
Method of Laying the same.
I, JOHN HENRY ROBERTS ROSE of 44 Bell Street, Henley on Thames, in the
County of Oxford, Engineer do hereby declare the nature of this invention, to be as
follows:
This invention relates to a new or improved method of laying and jointing pipes
for the conveyance of sewage water or other liquids. The novel features of this
invention (the detail portions of which may be made in the ordinary materials of
metal, stoneware or concrete) are firstly; the form of the pipes which may be alike
at both ends and provided with conically bevelled flanges or where designed for
connecting to pipe drains of former construction provided at one end with the said
flange and at the other end with socket and spigot of the usual form, secondly; the
invert blocks in which the pipes rest, either wholly or at the ends and lock firmly
when the joints are completed, thirdly; the general combination of the above, by
which the pipe conduits are thus laid in a manner superior to any in use-giving
greater advantages in solidity of bearing-economy of labor-simplicity and security
of jointing against either disturbance or entry of water from without, or escape of
liquid from within the pipes-facilities for the removal and renewal of any pipe
accidentally broken, without disturbance to the rest-and also for adaptation of the
system in part, to pipe conduits laid with pipes of existing patterns, such as the
ordinary socket and spigot kind.
The blocks for the support of the pipes are shaped so as to support the under part
of the pipes and are provided with grooves for the reception of the said conically
bevelled flanges of the pipes.
These are placed together on the blocks and the groove between the two contiguous
flanges is filled up with cement or luting.
The joints may then be covered if desired with a suitable covering block. The
blocks may be provided also with longitudinal perforations for the passage of subsoil
water and to reduce the weight of the blocks.

page_text: Improvements in Drain and other Pipes and in the Means and
Method of Laying the same.
I, JOHN HENRY ROBERTS ROSE of 44 Bell Street, Henley on Thames in the
County of Oxford, 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 relates to pipes and to the method of laying and jointing the same for
the conveyance of sewage, water or other liquids. The novel features of this invention
are firstly; the form of the ends of the pipes which latter may be alike at both ends
and provided with conically bevelled flanges, or where designed for connecting to
pipe drains of former construction provided at one end with the said flange and at the
other end with socket or spigot of the usual form; secondly, the invert blocks in
which the pipes rest, either wholly or at the ends and lock firmly when the joints are
completed thirdly, the general combination of the above by which the pipe conduits
are thus laid in a manner superior to any in use-giving greater advantages in solidity
of bearing economy of labor, simplicity and security of jointing against either
disturbance or entry of water from without, or escape of liquid from within the pipes-
facilities for the removal and renewal of any pipe accidentally broken without disturbance
to the rest and also for adaptation of the system in part to pipe conduits laid with
pipes of existing patterns such as the ordinary socket and spigot kind.
Referring to the accompanying drawings:
Fig. 1 illustrates in section and elevation a conduit of special pipes (No. 1 pattern
Fig. 6) laid in invert blocks (No. 1 pattern Figs. 2, 3 and 4) the cement joint being
shown in "black."
Fig. 2 cross section of same on line A. A with the cement omitted for clearness of
illustration.
Fig. 3 a similar cross section on line B B.
Fig. 4 shows an invert block (pattern No. 1) in plan.
Fig. 5 illustrates a simliar block with extension for a junction (pattern No. 3;
Fig. 6 is a side elevation of pipes (No. 1 pattern) with improved form of ends.
Fig. 7 also a side elevation of such pipe (No. 2 pattern) but for connection with
an ordinary spigot and socket pipe.
Figs. 8 and 9 side and front elevation of disc stopper to pipe No.
Fig. 10 improved pipes laid in blocks (pattern No. 2) placed on bottom of trench
and spaces between filled with concrete.
Fig. 11 illustrates the same arrangement except that the concrete is dispensed
with, the blocks being sunk sufficiently to let the pipe bellies rest on trench bottom.
Fig. 12 invert block (pattern No. 2) in plan.

page_text: Fig. 13 invert junction block (pattern No. 4) in plan.
Figs. 14 and 15 illustrates the method of laying sewer or conduit with ordinary or
known pipes and invert blocks (pattern No. 2.)
In the improved form of the pipes (No. 1 pattern Fig. 6) both ends are alike
provided with a conically bevelled splayed projecting ring-so that when the pipes
are "butted" together the same form a wedge shaped groove to receive the cementing
material. Supposing a pipe to be broken after being laid in, this form permits of
its being removed and a fresh one substituted without disturbance of the adjoining
sound ones.
In ordinary cases, the arrangement shown in Fig. 11 would probably be preferred.
Here the pipes are laid with their ends butting together and inserted in the mortises
formed in the sustaining blocks (No. 2 pattern) made of ordinary stoneware, concreto
or other suitable material. The joints are then completed with a suitable cement,
which being made sufficiently fluid, is poured into the mortise and completely fills all
the vacant space in same not occupied by the pipe ends, up to the upper surface of the
blocks. The upper portion of the joint in the wedge shaped groove made by the ends
of the pipes coming close together is filled with cement similar in quality but mixed
more stifflv.
In Figs. 1, 2, 10 and 11 a cap is indicated should such be desired, the same having
an aperture shown at top-Fig. 2-through which the upper half of the joint could
be completed in the same manner as the lower half but in practice these caps are
not likely to be used. The pipes are held together temporarily during the
jointing by clips, afterwards removed and a proper "dolly" as it is termed being
kept inside the pipes and drawn forward pipo by pipe as the joint is made,
prevents any cement getting into the pipes and leaves the joint internally smooth
and clean.
In the method shown by Fig. 11 the blocks are sunk in the trench bottom
just sufficiently to allow of the pipes when placed in position resting with their
bellies solidly on the bottom of the trench and in the collars of the blocks.
A second mode of laying the conduit is shown by Fig. 10. In this the blocks are
simply placed on the trench bottom at the necessary level and the spaces between
them and under the bellies of the pipes are filled up with ordinary concrete, to the
level of the tops of the blocks and to the same width as these transversely.
A third mode and suitable for use where the trench bottom is of doubtful solidity
is shown by Fig. 1. Here instead of throwing an irregular amount of concrete from
the top into the trench bottom, the trench is paved with the invert blocks of No. 1
pattern which are of the same length as the pipes and placed so as to break joint with
them. These blocks are laid butt to butt like the pipes and form a wedge shaped
groove which is filled with cement, the pipes are then placed in the mortises and
jointed as before described. The invert blocks (as shown in Figs. 4 and 5 may be
further held together by the dowels at their ends, and the whole structure is thus well
locked together.
A fourth method of laying the pipe conduit is shown by Figs. 14 and 15.
Ordinary spigot and socket pipes are used in the first, and the pipes such as are used
at Henley-on-Thames in the second instance in combination with the invert blocks.
To prevent the breakage (and consequent leakage from or influx of subsoil water
into the sewer or conduit) which frequently takes place at the shoulders of junctions
owing to the difficulty of ramming the earth sufficiently at these points and sometimes
from mischief done in the attempt to ram the trench solidly. The junction invert
blocks Nos. 3 and 4 (Figs. 5 and 13) have been devised.
To admit of house connections &c. being added to the main stem-laid with ordinary
socket and spigot pipes the special pipe No. 2 (Fig. 7) has been designed.
The methods indicated it will be observed ensure the locking of the pipes well
together and prevent their being drawn apart by subsidence in the trench and also
overcome the difficulty of making the joints sound and watertight at their lowest
point where the work cannot be properly seen. Subsoil water is allowed a passage
under all the blocks by the grooves moulded in their bottoms see Figs. 2 and 3.

Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. Pipos having at one or each end a conically bevelled ring or flange substantially
as set forth.
2. The invert blocks substantially as and for the purpose set forth.
3. The combination of invert blocks with the improved or other pipes substantially
as and for the purpose set forth.
