City of Dublin, Ireland, for an Invention of "IMPROVEMENTS IN DRAIN PIPES,
AND IN THE METHOD OF LAYING THE SAME."
PROVISIONAL SPECIFICATION left by the said William Robert Maguire at
the Office of the Commissioners of Patents on the 18th May 1880.
«
WILLIAM ROBERT MAGUIRE, of 10, Dawson Street, in the City of Dublin,
Ireland. IMPROVEMENTS IN DRAIN PIPES, AND IN THE METHOD OF LAYING
THE SAME."
This Invention relates to improvements in drain pipes, and in the method of
laying the same, the object of the improvements being to provide cheap, and
efficient means for obtaining perfect smoothness of the interior surface of the pipes
at the joints, by enabling the workmen to easily reach the interior of the joints
after the pipes have been laid, and to enable the interior joints to be examined
after the pipes have been laid and finished without disturbing the pipes; also to
secure double cement joints on the lower half of the sockets for ensuring perfect
stanch joints, and to keep each pipe fair in the centre of its corresponding
socket.
In carrying out my Invention I employ for each alternate length of pipe the
conimon pipes of the trade, but each of the other alternate lengths of drain pipe is
constructed with an examining hole formed with a socket of about the same
diameter as the pipe, and provided with a stopper which is cemented down on the
same after the joints have been carefully smoothed and examined by the overseer,
or for a branch pipe to extend the opening up to the floor level to allow of
permanent inspection.
For each joint I provide a hollow inverted saddle which is filled with cement,
the saddle being of suitable length and semi-cylindrical, so as to follow half the
curve of the socket of the pipe; it is turned up on both edges so as to keep the
pipe central and give an even joint all round the corresponding socket, and to hold
the cement round the joint. The ordinary joint having been carefully laid in with
Portland cement will be held centrally in the socket by the saddle or cradle, so as
to secure even joints all round, and then the space provided by the hollow saddle
round the ordinary socket joint will be filled in with cement to form a second joint
on under half of the pipe.

WILLIAM ROBERT MAGUIRE, of 10, Dawson Street, in the City of Dublin,
Ireland. "IMPROVEMENTS IN DRAIN PIPES, AND IN THE METHOD OF LAYING
THE SANE."
This Invention relates to improvements in drain pipes and connections, and in
the method of laying the same, the object of the improvements being to provide
cheap and efficient means for obtaining perfect smoothness of the interior surface of
the pipes at the joints, by enabling the workmen to easily reach the interior of the
joints after the pipes have been laid, and to enable the interior joints to be
examined after the pipes have been laid and finished without disturbing the pipes;
also to secure double cement joints on the lower half of the sockets for ensuring
perfect staunch joints, and to keep each pipe fair in the centre of its corresponding
socket.
In carrying out my Invention I employ for each alternate length of tube the
common pipes of the trade, but each of the other alternate lengths of drain pipe is
constructed with an examining hole formed with or without a socket of about the
same diameter as the pipe, and provided with a stopper which is cemented down on
the same after the joints have been carefully smoothed and examined by the
overseer, or for a branch pipe to extend the opening up to the floor level to allow of
permanent inspection.
'
For each joint I provide a hollow inverted saddle which is filled with cement,
the saddle being of suitable length and semi-cylindrical or other suitable form, so
as to follow half the curve of the socket of the pipe; it is turned up at both edges
so as to keep the pipe central and give an even joint all round the corresponding
socket, and to hold the cement round the joint. The ordinary joint having been
carefully laid in with Portland cement will be held central in the socket by the
saddle or cradle, so as to secure even joints all round, and then the space provided
by the hollow saddle round the ordinary socket joint will be filled in with cement
in a soft or liquid state to form a second joint on the under half of the pipe.
But to make my-Invention better understood, I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a plan, and
Figure 2 is a perspective side view of several lengths of drain pipe constructed and
laid according to my Invention.
a, a, shew the lengths of drain pipe, which are of the ordinary construction, but
each alternate length b, b, I construct with an examining or inspection hole c formed.
with or without a socket d of about the same diameter as the pipe. These
inspection holes may be made round or oval, and will each afford easy means of
perfectly smoothing the interior of two joints, videlicet, one on either side, and will
give perfect facility for the careful inspection of every joint in the drain after it has
been made and finished; the said sockets are provided with loose stoppers or
covers, such stoppers being cemented down after the pipe joints have been
smoothed and examined, or branch pipes may be fitted to the sockets to allow of
extending the opening up to the floor level to admit of permanent inspection.
e, e, e, e, e, shew the hollow inverted cradles or saddles in which the end of one
length of pipe and socket of the next length rest; the ends f of the said cradles or
saddles e are fashioned to receive the pipes so as to hold the pipe and socket
concentric, so that a much more perfect and durable cement joint can be made than
by the system now in use, my arrangement allowing of the joints being equally
spaced all round without necessitating the use of wedges; it also allows of the joint
being got at all round, and the pipes being held steady and even instead of lying
loosely on the ground.

page_text: Further, this arrangement allows of a second and independent joint being made
on the lower half of the socket where the sowage runs, by pouring in liquid cement
round the first joint after it has set fast, thereby making a perfectly sound and
staunch joint independent of the workman's care, and one which will be open to
inspection.
Having now described my said Invention, and the best means with which I am
acquainted for carrying the same into effect, I wish it to be understood that what
I claim is,
Firstly. The peculiar construction of hollow saddle or cradle for receiving tho
socket and end respectively of two adjacent lengths of drain pipe, as hereinbefore
described and represented in the accompanying Drawing.
Secondly. The method of laying drain pipes by the employment of hollow saddles
or cradles, substantially in the manner and for the purposes hereinbefore described
and represented in the accompanying Drawing.
Thirdly. Constructing alternate lengths of drain pipes with inspection holes,
and the employment of the same in combination with alternate lengths of ordinary
drain pipes and saddles or cradles, substantially in the manner and for the purposes
herein before described and represented in the accompanying Drawing.
In witness whereof, I, the said William Robert Maguire, have hereto set my
hand and seal, this Sixteenth day of November, in the year of our Lord
One thousand eight hundred and eighty.
