PROVISIONAL SPECIFICATION.
An Improved Detachable Joint or Socket for Pipes and Conduits.
I, NIMROD SIMMONS B.SC. F.R.M.S. Civil and Mining Engineer of Glendale
Clifton in the City and County of Bristol do hereby declare the nature of this
invention to be as follows:-
:―
An improved pipe joint relating more especially to drain, water, or gas pipes
and consisting of a double socket of improved form disposed at the junction of
pipes in halves, and there held together on one side by a single or multiple hinge,
and on the other side by one or more bolts & nuts engaging with pairs of ears or
lugs. At the inner circumference of the socket, and at convenient distances apart,
are two or more annular channels, disposed on each side of the centre of the socket,
and formed for the reception of rubber or other packing as hereinafter
described.
The section through the channels at right angles to the length of the socket is a
polygon, preferably hexagonal, while the channel itself is semi-hexagonal in cross
section. In combination with the socket is a sleeve or collar of india rubber or
other elastic material, of the same cross section as the piping to be jointed,
preferably cylindrical with two or more beads or rings formed upon and being
part of it, so disposed as to enter into the annular channels formed in the socket as
before described.
In summary my invention consists of a socket of iron, steel, brass, stoneware, or
other suitable material formed in halves, or segments, hinged, and bolt compressed
upon an india rubber or other clastic sleeve or collar, the latter being of such form
as to fit upon the pipes to be jointed and having formed upon it beads or rings
engaging in annular channels formed in the iron or other socket. The beads and
channels are disposed on either sides of the junction in the pipes, and the compres-
sion of the socket halves upon the rubber sleeve has the effect of producing a
water tight and air tight joint as is intended and set forth herewith.

COMPLETE SPECIFICATION.
An Improved Detachable Joint or Socket for Pipes and Conduits.
I, NIMROD SIMMONS, B.Sc. of 8 Glendale Clifton in the City and County of
Bristol, Civil Engineer, 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:-
The said invention relates to an improved detachable joint for any kind of pipes,
but more especially for water pipes, soil pipes, drain pipes etc.
It consists of a socket in halves or segments of improved form, compressed upon
an elastic sleeve or collar.
Having reference to the accompanying drawings,
Fig. 1 is a front elevation of the joint as closed on a pipe P: the halves H. H.
being compressed by the bolts and nuts S engaging with ears or lugs E as shown.
Fig. 2 is an end elevation shewing the hinged joint J.
Similar letters of reference in each case apply to the same parts of the joint as
before described.
At C C Figs. 1 and 3 hollow beads are formed upon the joint circumferentially as
shown, and constitute channels of polygonal shape in cross section as shown in
Fig. 4, which is a section on the line C. D. Fig. 1.

page_text: Fig. 3 is a plan of the half socket, and shows the shape and position of the
channels formed in the hollow beads before mentioned. The joint can be made in
iron, brass, steel or any suitable material. In combination with the said socket is
used a sleeve or collar of india rubber or other elastic material stretched tightly
upon the butted junction in the pipes, and a comprehensive view of the said sleeve
is shown in Fig. 5, in which B. B. are beads formed upon the sleeve, and disposed
in such manner as to engage with the channels C. C formed in the joint as shown
in Fig. 3. The sleeve is extended beyond the beads as at W, to fill the ends of
the socket as desired.
The sleeve is also provided with a circumferential space M Fig. 6 whereby the
extensions or flaps F may be expanded against the circumference of the pipes by
hydraulic pressure automatically.
'
The action of the joint when compressed upon the pipes over the rubber or
elastic sleeve is not the same as obtains with semicircular straps on rubber rings,
but in virtue of the polygonal shape of the channels in my improved joint the
compressed force is concentrated upon the beads of the elastic sleeve
concentrically.
Having now particularly described the nature of this invention, and in what
manner the same is to be performed; I make claim to the following features.
1. A socket joint in halves or segments having two or more channels disposed
circumferentially at the inner periphery of the socket as a whole. The said
channels of polygonal shape in cross section as fully set forth herewith and shown
in Fig. 4.
2. The said joint or.socket in combination with an india rubber or other elastic
sleeve or collar as described, and having beads formed upon it to engage with the
channels formed in the socket for this purpose.
3. I also claim in the rubber or clastic sleeve, the formation of a circumferential
space as described, and for the purpose set forth, vis. The expansion of the. walls
of the said space as indicated in Fig. 6 at M and F-by hydraulic pressure
against the pipe and socket to form a tight joint when under pressure.
4. The combination of a socket in halves or segments, hinged and bolt com-
pressed upon a rubber or other elastic sleeve, and having polygonal channels
engaging with raised beads formed upon the said india rubber or elastic sleeve, and
for the purpose set forth, viz.-To form a watertight and airtight joint in any
length of piping, and to be easily detachable.
