PROVISIONAL SPECIFICATION.
Improvements in the Means of Connecting Pipes.
We WILLIAM HULME, Junior, of Moor Nook, Sale, in the County of Chester,
and JAMES HULME, of Moor Nook, Sale, in the County of Chester, and 267 City
Road, Hulme, Manchester, in the County of Lancaster, both Market Gardeners,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the manner of connecting the ends of
pipes by means of wedges, as described in the Specification of the Patent No. 3679
of 1890; the objects of this inventign are, in addition to what is therein stated, to
enable pipes that are constructed with the improvements herein after described, to
be laid in extended curves without requiring specially formed bends, or bends to be
placed at any required angle, and to neutralize the effects that would be produced
with rigid joints, from any inequality in the surface of the ground on which the
pipes may be laid.
In the accompanying drawing Fig. 1 is the socket end of the pipe, and Fig. 2 is
the end of a pipe intended to be connected thereto.
We construct the end of a pipe such as a that is intended to be inserted into the
socket b, with a narrow ring or projection c, the external diameter of which is of
a size that will fit within the socket b. We place a flat india rubber ring d on the
pipe at the back of the projection c, said ring being wider than the portion of the
pipe a extending beyond the projection c, so that it may lap over the end of
the pipe, or a ring of india rubber or other material may be placed at the end a¹
of said pipe. The end a¹ of the pipe a is placed within the socket b, with the
india rubber ring d in contact with the inner end e of said socket; wedges are
then driven into the holes f and f¹, at the back c' of the projection c, which will
thereby press the rubber between the inner portion of the socket b, and the end a¹
of the pipe a, and also the projection c.

By these means an unleakable joint is obtained, while permitting each pipe to be
deflected or to be moved to a moderate extent from a straight line, and elbow pipes
may be placed at any angle.

COMPLETE SPECIFICATION.
Improvements in the Means of Connecting Pipes.
We, WILLIAM HULME, Junior, of Moor Nook, Sale, in the County of Chester
and JAMES HULME, of Moor Nook, Sale in the County of Chester, and 267 City
Road, Hulme, Manchester, in the County of Lancaster, both Market Gardeners
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:―
This invention relates to improvements in the manner of connecting the ends of
pipes such as are or may be used for water, steam, gas, or for other purposes.

page_text: The objects of this invention are to obtain perfect and unleakable joints in pipes
which may be readily connected without the use of cement or other like substances
requiring the aid of experienced workmen to form the joint; to enable pipes that
are constructed with our said improvements to be laid in extended curves without
requiring specially formed bends, or bends to be placed at any required angle; to
neutralize the effects that would be produced with rigid joints if the ground on
which the pipes may be laid should be uneven; and to enable the pipes to be
disconnected without injury to the joints.
We attain these objects by the means hereinafter described and as illustrated in
the accompanying sheet of drawings in which
Fig. 1 is a side view of a pipe of any length constructed according to our
invention:
Fig. 2 represents an end A, and Fig. 3 an end B of a pipe such as is represented
by Fig. 1. placed in the positions required for inserting the end B within the end A
so as to form a joint as represented in Fig. 4, which is a longitudinal section of a
completed joint; Fig. 5 is an end view of the same :
Fig. 6 is a side view of a socket for connecting two ends of pipes that may have
required to be cut to make up a length of piping, and Fig. 7 is a transverse section
of said two ends of pipes united.
In these views similar letters refer to similar parts.
In this invention we construct pipes a which terminate at one end with a socket
as b, and the opposite end with a narrow ring or projection c, the external diameter
of which is such as to permit said ring to be easily inserted into the socket b. We
place an india rubber washer as d on the extreme end of the pipe a, said washer
being wider than the portion a¹ of the pipe a that extends beyond the aforesaid
projection c.
In order to form a joint, the end B of one pipe is inserted in the socket 6 formed
on the end A of another pipe, and cottar pins fare driven through the holes e
behind the ring or projection c, which thereby causes the overhanging portion of
the aforesaid india rubber washer d to be pressed forcibly in between the shoulder b¹
of the socket 6 and the end a¹ of the pipe a and also the projection c, as represented
in Fig. 4.
An india rubber washer or a washer of other material, may if preferred be
placed on the shoulder b¹ in the socket in lieu of the washer d or in addition
thereto.
In order to connect ends of pipes that may have required to be cut for the
purpose of making up a length of piping, we employ a loose socket as represented
in Fig. 6, in which we insert either one cut end a² of a pipe and one end as B, or
two cut ends a' and a³ as in Fig. 7. These ends of pipes are fixed and the joint
made in the manner herein before described, by slipping onto the ends of the pipes
the rings with india rubber washers d placed between said rings and the
shoulder and driving in behind the rings c¹ through the holes e, the cottar pins f
which thereby cause the india rubber washers to be pressed forcibly between the
rings c' and the shoulders as represented in Fig. 7.
By these means pipes with joints formed in the manner herein before described
may be laid in a curved line or at a moderate angle, and elbow pipes may be placed
at any angle without requiring the joints to be specially forined, and said pipes
may be immediately disconnected by withdrawing the cottars f.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed we declare that
what we claim is :-
1st. In pipes that are, or may be employed for water, steam, gas, and for other
purposes, the formation of joints by the combination and use of a fast or loose ring
or projection as c, that is caused to press against an india rubber or other pliable
washer as d in a socket as b by means of cottar pins or wedges as ƒ in the manner
and for the purpose substantially as herein before described.

page_text: 2nd. In pipes that are employed for water, steam, gas, and for other purposes,.
the use of a socket as represented in Fig. 6, in combination with rings c', pliable
washers d, and cottar pins or wedges f, for the purpose and in the manner
substantially as herein before described.
Dated this 18th day of August 1894.
