PROVISIONAL SPECIFICATION.
Improvements connected with Hose Couplings used for High
Pressure Hydraulic and Steam Machinery.
J, JOSEPH THOMPSON, of The Sphincter Grip Armoured Hose Company,
Limited, 9 Moorfields, London, and Emerson Street, Southwark, London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, certain means for uniting flexible armoured hose
to couplings in an easy and expeditious manner.
For the purpose of this invention, I employ a socket, with a contracted end, into
which segmental pieces are fitted, each piece having a double inclined rib on its
exterior and with undulating, or a screw threaded inner face to engage the
armouring of the hose, so that when the end of the armoured hose is inserted
into the socket and the segments put in place, a screwing up of a ferrule, or it
may be a nozzle lodged in the flexible hose draws the segments and the hose in
to close contact, and makes a firm joint, or connection.
I have described a half coupling, the other half having segmental pieces also,
capable of being acted upon by the same screw ferrule to draw the two ends of
hose lengths to make a continuation thereof.
The ferrule may be in connection with a tee provided with hat shaped or with
cup leathers for a right angled joint, the socket or sockets being so arranged on
the flexible hose, that it can turn axially when it has a tendency to curl under
the internal pressure.
Dated this 17th day of November 1892.

COMPLETE SPECIFICATION.
Improvements connected with Hose Couplings used for High
Pressure Hydraulic and Steam Machinery.
1, JOSEPH THOMPSON, of The Sphincter Grip Armoured Hose Company,
Limited, 9 Moorfields, London, and Emerson Street, Southwark, London,
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 has for object, certain means for uniting flexible armoured hose
to couplings in an easy and expeditious manner.
The invention will be fully understood by referring to the annexed drawings.
Figure 1 is a part sectional elevation of a complete pair of couplings for
connecting the adjoining ends of two armoured flexible hose pipings.
Figure 2 perspective elevation of three segmental pieces with screw thread
interior to engage the armouring wire of the hose, and with a double incline or
rib on the outside for the nip of the socket when screwed up on the nut.
Figure 3 part sectional elevation of a complete pair of couplings for armoured
flexible hose with the intermediate nut or "union," (see Figure 4 detached view)
right and left hand screw threaded for the sockets to travel on and draw the
segments into close contact with the hose ends on their exterior, the interior being
pinched against internal uozzles.

page_text: Figure 5 is an elevation of a single coupling for connecting a flexible armoured
hose to a fixed pipe.
Figure 6 part sectional elevation of a single coupling in connection with a swivel
tee, which is in communication in any desired manner with a source of supply on
exit at any right angle circumferentially from, or around the axis of the coupling.
Figure 7 is an end view showing the socket encircling the segments.
For the purpose of this invention, I employ a socket A with a contracted end,
into which segmental pieces B, B, are fitted, each piece having a double inclined
surface D D formed upon the middle of the segments B or two inclined surfaces D, D
at each end of the segments B as at Figure 3, and with undulating, or a screw
threaded inner face E to engage the armouring F of the hose G, so that when the
end of the armoured hose F is inserted into the socket A, and over the nozzle I
and the segments B put in place, a screwing up of a ferrule H, draws the
segments B, B, and the hose in to close contact, with the same and makes a firm
joint, or connection.
I have described a half coupling, the other half having segmental pieces also
capable of being acted upon by the same screw ferrule, or nut H, or different screw
ferrules H, H, may be employed to draw the two ends of hose lengths to make a
continuation thereof.
The ferrule may be in connection with a tee K provided with hat shaped or with
cup leathers L, L, for a right angled joint, the socket A, or sockets A, A being so
arranged on the flexible hose G that it can turn axially when it has a tendency to
curl under the internal pressure.
The swivel tee may be on a double coupling for distributing from two outlets, if
desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The construction of couplings for flexible armoured hose, as herein before
described and as shown on the annexed drawings, and consisting of internal
threaded segments, having external inclined faced ribs, which by outside socket
and inside nozzle enable such hose or hoses to be coupled up, or be connected
with a swivel joint, as set forth.
