page_text: LETTERS PATENT to Herbert John Jones, of Peckham Rye, in the
County of Surrey, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF DRAIN PIPES, AND IN THE MODE OF OBTAINING ACCESS
THERETO FOR FORMING CONNECTIONS THERE WITH OR FOR CLEANSING OR
EXAMINING THE SAME.'
"
Sealed the 6th December 1870, and dated the 26th September 1870.
PROVISIONAL SPECIFICATION left by the said Herbert John Jones
at the Office of the Commissioners of Patents, with his Petition,
on the 26th September 1870.
I, HERBERT JOHN JONES, of Peckham Rye, in the County of Surrey,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF DRAIN PIPES, AND IN THE MODE OF OBTAINING ACCESS
THERETO FOR FORMING CONNECTIONS THEREWITH OR FOR CLEANSING OR EXAMINING
THE SAME," to be as follows:-
"
This Invention consists in constructing drain pipes in the following
manner-Instead of forming a socket entirely around one end of each

page_text: length, as now practised, I remove a portion of the said socket, and also
a portion of the pipe so as to leave an opening in the pipe, and this
opening I propose to enclose by a cap or cover made water-tight with
cement or other composition. In laying a main of pipes constructed
as above described care must be taken to place the opening in each
length of pipe uppermost, so that when it is required to examine the
drain it is simply necessary to open the ground until one of the afore-
said caps is uncovered, the joint must then be broken, and the cap
removed. During this time the flow of sewage water is uninterrupted
and cannot escape out of the opening, and by making each length of
pipe two feet eight inches long instead of two feet I reduce the number
of joints, which is of importance in a long main. To form connections
with the main by pipes leading from houses and other buildings and
places I form the cap before mentioned upon one of the lengths of cross
pipes, fitting the opening in the main pipe as before described; by these
means I establish a communication between the connecting pipes and
the main drain. The aforesaid caps are to be so shaped as to complete
the sockets on the main pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Herbert John Jones in the Great Seal Patent
Office on the 19th December 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HERBERT
JOHN JONES, of Peckham Rye, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of September, in
the year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Herbert John Jones, Her
special licence that I, the said Herbert John Jones, my executors,
administrators, and assigns, or such others as I, the said Herbert John
Jones, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might

page_text: make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF DRAIN PIPES, AND IN THE MODE
OF OBTAINING ACCESS THERETO FOR FORMING CONNECTIONS THEREWITH OR FOR
CLEANSING OR EXAMINING THE SAME," upon the condition (amongst others)
that I, the said Herbert John Jones, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Herbert John Jones, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
This Invention consists in constructing drain pipes in the following
manner-Instead of forming a socket entirely around one end of each
length of pipe, as now practised, I remove a portion of the said socket
and also a portion of the pipe, so as to leave an opening in the pipe, and
this opening I propose to enclose by a flanged cap or cover made water-
tight with cement or other composition if necessary.
To
When it is required to examine the drain it is simply necessary to
open the ground until one of the aforesaid caps is uncovered; the cap
may then be removed. During this time the flow of sewage water is
uninterrupted, and cannot escape out of the opening, and by making
each length of pipe two feet eight inches long instead of two feet I
reduce the number of joints, which is of importance in a long main.
form connections with the main by pipes leading from houses and other
buildings and places I form a junction upon the cap before mentioned,
fitting the opening in the main pipe as before described. By these
means I establish a communication between the connecting pipes and
the main drain. The aforesaid caps are to be so shaped as to complete
the sockets on the main pipes.
And in order to explain my said Invention more completely I will
now proceed to describe the best means I am acquainted with for carrying
the same into practical effect, reference being had to the illustrative

page_text: Drawing accompanying these resents, and LU the numeral figures and
letters of reference marked thereon respectively as follows:
DESCRIPTION OF THE DRAWING.
Figure 1 represents a side elevation of three lengths of drain pipes
constructed according to my said Invention shewing my improved
method of connecting them together and to other branch connecting
pipes Figure 2 represents a transverse and vertical section taken
through the line A, B, at Figure 1. Figure 3 is a side elevation of one
of the caps herein-after more particularly described and referred to. At
each of the foregoing Figures I employ similar letters of reference to
denote corresponding parts wherever they appear at each of such said
Figures respectively. A, B, C, mark three lengths of my improved
drain pipes, each formed with a socket at D, a portion of the socket and
also of the pipe being removed during the manufacture of the pipe, as
denoted at E on that length of pipe marked A at Figure 1, so that when
the plain end of the next length of pipe is inserted into the socket of the
pipe A an opening will be left at D for access to the interior of the
drain, supposing a number of of pipes of the above construction to be
connected together.
The cap G shewn at Figure 3 is intended to fit over the opening D,
the flanged parts a, b, fitting over the socket end of each length of pipe,
as shewn on the length of pipe marked B, thus completing the socket,
which may be securely fixed to the adjoining length of pipe and a water-
tight joint be made at such part and also around the opening D and
those parts of each length of pipe over which the cap G is fitted.
The length of pipe marked C shews the form of construction of cap I
propose to employ when it is required to form connections between pipes
leading from houses and other buildings and places with a main drain.
For this purpose instead of making the cap G of the shape represented at
Figure 3 I form it with a short cross pipe H with an opening therein com-
municating with the inside of the drain pipe and drain. The pipe H is
formed with a socket at one end, as at I, Figure 1, to receive another length
of pipe or series of lengths as may be desired, which may either be of the
ordinary kind, or of my improved construction, which is preferable, as in
case of any obstruction the interior of these pipes, as well as those of the
main drain, can be inspected or got at without removing any of the

page_text: lengths of pipes or breaking joints thereof, as commonly practised when
drain pipes of the ordinary kind are employed, it being simply necessary
to remove the caps G to obtain access to the interior of the drain, as
before stated.
Having now fully described and set forth the nature and object of my
said Invention for "Improvements in the Construction of Drain Pipes,
and in the Mode of Obtaining Access thereto for Forming Connections
therewith or for Cleansing or Examining the same," together with the
best means I am acquainted with for carrying the same into practical
effect, I would remark in conclusion that I hereby declare my Invention
to consist in, and I claim, constructing and connecting together drain
pipes in the manner above described with reference to the accompanying
Drawing for the purposes above stated.
In witness whereof, I, the said Herbert John Jones, have hereunto
set my hand and seal, this Thirteenth day of December, in the
year of our Lord One thousand eight hundred and seventy.
