COMPLETE SPECIFICATION.
Improvements in or connected with Pipe Joints.
I, 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 an 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, said joint being quickly and easily made. The
invention bereinafter described consists of improvements upon my former Letters
Patent No. 13083 A.D. 1895.
In carrying my invention into practical effect, the pipe is manufactured in
suitable lengths and quite plain at each end, no socket or the like being formed
thereon, the socket or connecting piece being formed quite separately and in two
parts. The socket or connecting piece, when the two parts it comprises are
brought together, consists of an annular body having at each side a small inwardly
projecting flange or ring designed to support the end of the pipe, said body
connecting or joining together two lengths of pipe the ends of which are passed
into same, one at each side, until they meet within the said body, each of the said
lengths of pipe being supported by one of the aforesaid rings or flanges in such a
manner as to leave an annular space or recess around them, designed to contain
pitch, cement or the like which is passed into the socket or connecting piece
through a suitable opening formed in same. The socket or connecting piece which
is formed in two parts for convenience in making the joint, is connected together
by means of lugs formed upon each part, which are brought together and secured
in position by means of bolts or the like passed through suitable holes or
perforations formed therein.
By this means a thoroughly reliable and efficient joint is quickly and easily
made while the bore of the pipe is quite smooth and flush throughout, this improved
joint possessing the further advantage of allowing a broken or damaged length of
pipe to be easily removed and replaced by a fresh length.
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 side elevation of the ends of two lengths of pipe showing the two
parts of the socket or connecting piece before making the joint. Fig. 2 being a
plan of the same parts after making the joint.
Fig. 3 is a side elevation partly in section of the pipes and socket or connecting
piece in position ready for making the joint and
Fig. 4 is a section on line x, x of Fig. 3 but with the joint shown as completed.
Fig. 5 is a view of one of the parts of the socket or connecting piece.
The pipes p, pl are made quite plain at the ends as shown while the socket or
connecting piece is made in two parts a' and furnished on each side with a ring
or flange, (Fig. 3). The ends of the pipes p, p' are passed into the socket or
connecting piece one on each side in such a manner that they meet in the centre of
same (Fig. 3) the pipe p being supported by the ring or flanger and the pipe pl by
the ring or flange, while the spaces thus left is filled with cement or the like c
which is passed through the opening o formed in the top portion of the socket or
connecting piece. I may when making the joint first fill the lower portion a' of
the socket or connecting piece with the pitch, cement or the like being used

page_text: and then place the top portion a in position which is then filled through the
opening o.
In order to connect the two parts a, a¹ of the connecting piece or socket together,
Tugs 1, 1, and 1, are formed on same (Fig. 4) which are secured by means of
bolts b, b, (Fig. 2). The socket or connecting piece may be formed of earthenware,
iron or other suitable metal or material, while in some cases or where the pipes to
be joined are of small diameter the said socket or connecting piece might be made
in one piece or part, then consisting of a hollow drum-like body with an opening
at each end through which the pipe could be passed, the connecting piece being
then filled with pitch, cement or the like, passed through a suitable opening formed
therein.
By the above description and with reference to the accompanying rawings it
will be seen that a thoroughly reliable joint can be easily effected, while in the
event of it being necessary to replace a damaged length of pipe it is only necessary
to remove the top portion a of the socket or connecting piece when the joint could
be readily broken and the damaged pipe removed, a fresh length being then
inserted and the joint again made in the manner hereinbefore 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. In the method of joining or connecting pipes herein described, the socket
or connecting piece comprising the parts a, a in combination with rings or
flanges r, and lugs l, l, and 1,, or the like, for joining them together,.
substantially as herein described and shown and for the purposes specified.
2. The improved method of and means for joining together lengths of pipe of
various descriptions substantially as herein described and shown and for the
purposes specified.
