COMPLETE SPECIFICATION.
Improvements in or connected with Pipe Joints.
1, ABRAHAM JONES, of 89, St. John's Road, Boxmoor, Herts, Plumber, 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 improvements in or connected with pipe joints and! has for
its object a new or improved method of connecting or joining together lengths of
pipes of various descriptions in such a manner that a thoroughly effectual and
permanent joint is obtained.
In carrying my invention into practical effect one end of the pipe to be joined is.
provided with a socket in, the usual manner, while within the said socket a narrow
ring or flange is formed in such a manner that the end of the second pipe, when it
is placed within the socket, rests or bears upon, or is supported by the said ring or
flange, so as to leave an annular space between the inner surface of the socket and
the end of the pipe entering same, which space is then filled in with pitch, or cement.
of any description such as usually employed for the purpose of making pipe joints,.
the said cement, pitch or the like being passed through any conveniently shaped
opening or openings formed in the side of the socket. By this means the pitch,.
cement or the like used in making the joint is distributed in a layer of equal thickness
around same, instead of being of greater thickness at the top than at the bottom.
which now frequently occurs in the ordinary process of joint making, while the bore.
of the pipe is quite smooth and flush right through, without presenting a broken or
uneven surface or irregularities at the joint. In cases where pipes of larger diameter.
are to be joined, two or more openings may be formed in the socket so as to allow
of the cement or the like being more readily poured or passed into same, while where
it is necessary, the pipe may be heated in any suitable manner so as to allow of the.
socket being more conveniently and expeditiously filled with cement or the like.
My invention is more particularly applicable to earthenware pipes such as used.
for house sanitation, drainage etc., but I do not restrict myself in this respect, as my
invention may be applied to pipes of every description for which it is suitable.
In order that my invention may be more fully understood, I will now proceed to.
describe same with reference to the accompanying drawings, in which
Fig. 1 is a sectional elevation of the ends of the two pipes before the joint is.
made, Fig. 2 being a similar view when the joint is completed.
Fig. 3 is a plan of the pipe joint and Fig. 4 a cross section on line x, x, of
Fig. 3.
Fig. 5 is an end view of the flanged end of the pipe showing a slight
modification.
According to this invention one end of the pipe is provided with a socket 8-
within which the ring or flanger is formed in such a manner so as to support the end e
of the second pipe pas shown in Fig. 2, viz.: so as to leave an annular space all
round same which is filled with pitch, cement or the like, through the opening o,
the said cement or the like, when the space within is filled, being smoothed off
flush with the surface of the pipe. In cases where the pipe is of large diameter
additional openings o', o³, are provided in the form of projecting lips or cups
which communicate with the interior of the socket and by which means the
lower part of the pipe socket is first filled, the cement being then allowed to.

page_text: set or the tops of the cups covered by means of pieces of slate or in any other
convenient manner, and the rest of the socket filled through the opening o as hereiu
described.
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
1. The improvements in or connected with pipe joints consisting of the socket s
furnished with ring or flange r for supporting end e of second pipe p' in such a
manner that an annular space is left round same, to be filled with pitch, cement or
the like through opening o substantially as herein described and shown and for
the purposes specified.
2. In the method of pipe joint making such as above claimed the modification
described and shown with reference to Fig. 5 of the accompanying drawings.
3. The improvements in or connected with pipe joints substantially as herein
described and shown and for the purposes specified.
