Improved Coupling for Rubber or other Hose.
I JOSEPH THOMPSON of The Sphincier Grip Armoured Hose Company Limited,
63 Fore Street City of London do hereby declare the nature of my said inven-
tion to be as follows:--
The coupling is specially constructed to be used in conjunction with wire
armoured rubber or other hose, that is having a strong wire firmly coiled on
the outside of same.
The invention consists in constructing the body of the coupling with a
recessed spiral for its entire length to fit the outside spiral wire of hose, the said
coupling to be made in two or more parts or it may be only divided for a part
of its length and after it is screwed on to the said wire armour it is firmly clamped
to same by bolts or other means.
The body of the coupling for a part of its length has an ordinary screw thread
formed on the outside of same on which is fitted a nut with a corresponding
thread, this nut is formed with a shoulder at one end on its inside which fits
against a corresponding shoulder on a conical or taper pipe and on screwing
this nut on to the body of the coupling the conical or taper pipe is forced into
the hole in the centre of hose expanding the hose firmly into the end of the
coupling, at the same time making a tight joint between the pipe and hose
and thus io machine.
The body of the coupling on the outside of the hose is made somewhat longer
than the part of hose wherein the taper pipe fits so that when the pressure is
admitted into the hose it is expanded by said pressure firmly to the spiral
armour and the spiral armour is forced firmly into the corresponding spiral
formed in the body of coupling thus forming a firm connection between the hose
and coupling and the more pressure admitted to hose the more firm is the con-
nection between hose and coupling.
By a modification of said coupling it can be adapted to unarmoured hose.

· Improved Coupling for Rubber or other Hose.
1 JOSEPH THOMPSON of The Sphincter Grip Armoured Hose Company Limited
9 Moorfields, City of London, do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
The coupling is specially constructed to be used in conjunction with wire
armoured rubber or other hose, that is having a strong wire firmly coiled on
the outside of same.
The invention, which is clearly represented in the annexed drawings, Figure 1
a longitudinal section, Figure 2 an elevation, Figure 3 end view from right

page_text: hand side of Figure 1. Figure 4 part sectional end view from left hand side of
Figure 1, consists in constructing the body A of the coupling with a recessed
spiral for its entire length to fit the outside spiral wire B of hose C, the said
coupling A being divided for a part of its length or it may be made in two or
more parts and after it is screwed on to the said wire armour it is firmly clamped
to same by bolts D) or other means.
The body A of the coupling for a part of its length has an ordinary screw
thread formed on the outside of same, on which is fitted a nut E with a corre-
sponding thread. This nut E is formed with a shoulder F at one end on its
inside which fits against a corresponding shoulder G on a conical or taper pipe H
and on screwing this nut on to the body A of the coupling, the conical or taper
pipe H is forced into the hole in the centre of hose C expanding the hose firmly
into the end of the coupling A at the same time making a tight joint between
the pipe and the hose and thus to machine. The body A of the coupling on the
outside of the hose C is made somewhat longer than the part of hose wherein the
taper pipe fits so that when the pressure is admitted into the hose it is expanded
by said pressure firmly to the spiral armour and the spiral armour is forced
firmly into the corresponding spiral formed in the body of the coupling, thus
forming a firm connection between the hose and coupling and the more pressure is
admitted to the hose the more firm is the connection between hose and coupling.
When the coupling is to be used for connecting hose together, one end of a
hose pipe may be connected to the extension I, having the nut F, so that when
coupled to another pipe the nut E has only to be screwed on to the body A, the
tapered end H entering the hose pipe as explained, or instead of attaching a hose
pipe to the extension I it can be fastened to another coupling constructed in the
same manner as that shewn at Figure 1, with the exception that the extension I
of the tapered socket H is made somewhat larger and with a female screw thread
for screwing on to the extension I when coupling hose together. When the
coupling is to be attached direct to a tap or stand pipe the extension I may be
screwed direct into same or an union socket may be attached to the extension I
for coupling purposes.
By a modification of said coupling it can be adapted to unarmoured hoses.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is:-
1. The improved coupling, constructed and fixable in the manner described
and substantially as shewn on the annexed drawings when employed for the
purpose set forth.
2. Screw threading the inside and the outside of a split socket, the inner
thread to correspond to the spiral wrapping of the hose covering wire and the
outer corresponding to that of a nut or its equivalent for use with a conical
nozzle for spreading the enclosed end of flexible hose as set forth and sub-
stantially as shewn on the drawings.
