PROVISIONAL
SPECIFICATION.
Improvements in or connected with Drain and other Pipes
or Tubes.
I, FERGUS THOMAS, of Upper Wortley, City of Leeds, County of York,
Manager, do hereby declare the nature of this invention to be as follows:-
Hitherto drain pipes have been joined together by placing the straight end of
one pipe into the socket end of another pipe, and afterwards filling up such socket
with clay or other suitable packing; and in practice it. has been found that the
ends of such pipes are not placed close together, thus allowing water to accumulate
at each joint, which softens the clay in the sockets, and eventually washes it out of
such sockets, thereby causing serious damage. By this arrangement also,
putrefaction is caused by the accumulation of foreign matter at the joints.
The object of my invention is to remedy these serious objections, and to so
connect the ends of drain, and other pipes that a perfectly sealed joint is obtained,
at the same time such joint is of a cheap, durable, and efficient character.
According to my invention I groove or otherwise serrate the extreme end of each
pipe to be connected, and after dipping each end of such pipes in water, cement in
a liquid or plastic state is put into the grooves or serrations in the pipe ends, such
grooved ends being left unglazed for the better adhesion of the cement. The ends
are then placed together, but before pressing them tightly, a little water is thrown
inside the socket, so as to run down each side of the pipe over the cement, when
the ends are firmly pressed together, thus making a perfectly sealed joint; the
cement in one pipe end mixing and adhering with the cement in the other pipe end,
forming thereby a ring round or between the pipe ends, which cement ring cannot
be washed out. The pipe ends are thus brought close together and present a
perfectly smooth surface throughout their length, consequently no space or opening
is left at each joint where water or foreign matter can lodge, and the tendency to
loosen the joint or to putrefaction is entirely obviated.
When the cement in the pipe ends is set, the socket can be filled up with clay or
cement, and the ordinary sockets for clay packing may be employed in conjunction
with my above described joint, or short sockets may be used, and cement packing
instead of clay.
My arrangement of joint above described is equally applicable to all sizes of
pipes and tubes, as well as to unsocketed pipes, well tubes, and other analogous
articles.

COMPLETE SPECIFICATION.
Improvements in or connected with Drain and other Pipes
or Tubes.
I, FERGUS THOMAS, of Upper Wortley, City of Leeds, County of York,
Manager, 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 :-
Hitherto drain pipes have commonly been joined together by placing the straight

page_text: end of one pipe into the socket end of another pipe, and afterwards filling up such
socket with clay or other suitable packing; and in practice it has been found that
the ends of such pipes are frequently, not placed close together, and in such cases
allow water to accumulate at each joint, which softens the clay in the sockets, and
eventually washes it out of such sockets, thereby causing serious damage; also
putrefaction is caused by the accumulation of foreign matter at the joints.
The object of my invention is to remedy these serious objections, and to so
connect the ends of drain and other pipes that a perfectly sealed joint is obtained,
at the same time such joint is of a cheap, durable and efficient character.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer to
like parts in both figures.
Figure 1 is a longitudinal section showing pipes constructed in accordance with
my invention, and Figure 2 is an end elevation of same.
According to my invention each pipe A to be connected, is grooved or otherwise
serrated at B, at each extreme end thereof; and after dipping the ends of such
pipes in water, cement in a liquid or plastic state is put into the said grooves or
serrations B in the pipe ends, such grooved ends being left unglazed for the better
adhesion of the cement. The ends are then placed together, and a little water is
thrown inside the socket C, so as to run down to the joint of the pipes A over the
cement, after which the ends are firmly pressed together, thus making a perfectly
sealed joint, the cement in one pipe end mixing and adhering with the cement in
the other pipe end, forming thereby a ring D round or between the pipe ends, as
shown at Fig. 1, which cement ring D cannot be washed out. The pipe ends are
thus brought close together and present a perfectly smooth inner surface throughout
their length, consequently no space or opening is left at each joint where water or
foreign matter can lodge, and the tendency to loosen the joint, or to putrefaction,
is entirely obviated.
When the cement in the pipe ends is set, the socket C can be filled up with clay
or cement E as shown at Fig. 1. Ordinary sockets for clay packing may be
employed in conjunction with the above described joint as shown, or short sockets
may be used with cement packing instead of clay.
My arrangement of joint above described is equally applicable to all sizes of
pipes and tubes, also to unsocketed pipes and tubes, well tubes, and other analogous
articles.
Having now particularly described and ascertained the nature of my said
invention and in what manner the sanie is to be performed I declare that what
I claim is
1. In drain and other pipes, grooves or serrations in the pipe ends for holding
plastic or liquid cement, substantially as and for the purposes herein set forth.
2. In drain and other pipes, the combination of the grooves B and the ring of
cement D, substantially as and for the purposes herein set forth.
3. The combination of the pipes A, grooves or serrations B, socket C, cement D,
and packing E, substantially as and for the purposes herein set forth.
