PROVISIONAL SPECIFICATION.
Improvements in Joint Connections for Taps, Cocks, Valves, Pipes,
or the like.
J, SCOTT FREELAND KELLY, of Bridge End Foundry, Cardigan, in the County
of Cardigan, Engineer, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Frank Sharp, S.E. Wznaad, India,
Engineer) to be as follows :-
This invention relates to improvements in joint connections for cocks, taps, valves,
pipes or the like used for the control, regulation or conveyance of liquids and fluids.
It consists essentially in making the joint so that the liquid or fluid passing
therethrough tends to increase the tightness or efficiency of the joint according to
the pressure of such liquid or fluid.
In carrying out my invention I provide the tap, pipe, cock or valve (which I
will hereinafter refer to as the tap) with one or more projections either formed
integral with the main body of the tap or otherwise as may be found convenient
and in close proximity to the projections provide an annular groove into which I
At the bottom of the annular
spring an elastic ring of india-rubber or the like.
groove I drill one or more holes which pass through the body of the tap into the
interior thereof, thus communicating with the liquid or fluid way of the tap.
The part to which the tap is to be connected I form with an annular groove in
its interior of sufficiently large outside diameter to allow of the projection or
projections on the tap being turned round therein. One or more slots are formed
in the connecting part to allow of the projections on the tap passing into it and
one or more slots or recesses for retaining the projections when the tap has been
turned a portion of a revolution about its axis. The elastic ring on the tap fits
against the interior surface of the connecting part and forms a joint therewith.
In coupling or making up the joint the tap is inserted in the connecting part and
turned part of a revolution about its axis, and pulled forward till the projections on
the tap butt against the end of the recesses. Steam, air, water or the like may
now be turned on from the main supply and passing through the tap some of it
forces its way into the holes and annular groove, pressing the elastic ring against
the connecting part and forming a tight joint.
It will be obvious that a joint such as described will have but little wear and tear
whilst it is applicable to all or nearly all kinds of taps, cocks, valves or pipes. It
will also be obvious that the joint may be applied to one or more ends or branches
of a tap.

Improvements in Joint Connections for Taps, Cocks, Valves, Pipes,
or the like.
I, SCOTT FREELAND KELLY, of Bridge End Foundry, Cardigan, in the County
of Cardigan, Engineer (a communication from abroad by Frank Sharp of
S.E. Wznaad India, 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 :-
This invention relates to improvements in joint connections for cocks, taps, valves

page_text: or the like used for the control, regulation or conveyance of liquids and fluids, and
has for its object the provision of a joint which will increase in tightness or
efficiency as the pressure of the liquid or fluid passing through it increases.
My invention therefore consists essentially in forming on one part of the joint
piece an annular groove into which fits an indiarubber or other flexible ring said
groove communicating with the interior of the joint piece by one or more holes
through which the liquid or fluid may flow and come into contact with the flexible
ring, pressing the latter against the interior surface of the second piece forming
the joint and making the whole fluid or liquid tight. My invention also relates to
means for preventing the forcing of the joint asunder by the liquid or fluid passing
through it.
The invention will be fully described by the aid of the accompanying drawings
wherein I have only shown the joint connection as applied to a cock as it will be
obvious to practical engineers how the connection may be adapted to valves, taps,
pipes or the like without the aid of drawings.
Fig. 1 is an elevation of a cock with the improved joint applied.
Fig. 2 an elevation of a nipple forming one part of the joint.
Fig. 3 a longitudinal section of the cock.
Fig. 4 a similar section of the nipple and
Fig. 5 an end elevation of nipple.
In these A is the body of the cock near one end of which I form one or more
projections a either integral with the shell of the cock or otherwise as may be found
convenient. In close proximity to the projections a I form an annular groove B,
in the shell A, into which I spring an elastic or flexible ring of indiarubber or
the like. At the bottom of the annular groove one or more holes are drilled
which pass through the body of the cock and communicate with the liquid or fluid-
way C, thereof.
This portion of the cock might be termed the spigot portion of
the joint, and the other portion of the joint the socket.
This socket portion I have shown as consisting of a nipple D formed with an
annular grooved in its interior sufficiently deep to allow of the projections a being
turned round therein in a direction concentric with the axis of the cock. One or
more slots are formed in the connecting part or nipple to allow of the pro-
jections a passing into it and one or more slots or recesses are also formed for
retaining the projections in place when the cock has been turned round in the
direction named. The elastic or flexible ring fits against the interior surface E
of the nipple and forms a joint therewith.
In coupling or making up the joint the spigot is inserted in the nipple and turned
part of a revolution about its axis. It is then pulled forward a little until the
projections a are butt against the ends of the recesses d". Steam, air, water or the
fike may then be turned on from the main supply and passing through the cock
some portion of it forces its way through the holes and presses the flexible ring b
against the interior surface E of the nipple D and thus forms a liquid or fluid-tight
joint which increases in tightness or efficiency as the fluid or liquid passing through
it increases in pressure.
It will thus be seen that the joint is very simple in construction and that it
will have but little wear and tear whilst it is applicable to all or nearly all kinds
of taps, cocks, valves or pipes. It will also be obvious that the joint may be
applied to one or more ends or branches of a tap or cock and that the socket
piece may be replaced by the spigot piece and vice versa as may be found most
convenient.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In joint connections for cocks, taps, valves, pipes or the like the use of a
flexible ring fitting in an annular groove on the spigot portion of the joint, said ring
being pressed outward by the fluid or liquid passing through the joint, and causing

page_text: it to form a fluid or liquid-tight joint with the surface in the nipple substantially
as described.
2. In joint connections such as set forth in Claim 1 the means substantially as
described for preventing the joint pieces being forced asunder by the liquid or fluid
passing therethrough.
3. Joint connections for cocks, taps, valves, pipes or the like constructed and
arranged substantially as described and shown.
