page_text: Figure 1 in the annexed drawing snows in elevation the ends of two Пexible pipes
joined together and made fast.
Figure II shows the same in section.
The joint consists mainly of a cylindrical part A screwed on its outer diameter to
receive the tapped ends of the nuts Cand having at each end a plain conical part B of
smaller diameter to receive the hose pipe D.
The inside of the nut C is tapped at one end in the usual manner to fit the screw on
the outer diameter of A and the other end is formed into a conical part slightly
rounded at its edges, having the same taper as the conical end B the smaller diameter
of this part being sufficient to admit the hose pipe D the pipe being pressed on to the
conical end B and becoming thereby slightly expanded the nut C is then screwed on
to the outer diameter of A thus bringing the conical portion of the nut in contact with

page_text: the hose pipe D thereby forcibly compressing the hose between the two conical parts
and forming a firm and perfectly watertight joint.
Figures III and IV show the arrangement by which a flexible pipe can be joined
to iron or any other kind of pipe Figure III being in elevation and Figure IV in
section.
In this case one end of the cylindrical portion A is formed in a similar manner to
that shown on Figures I and II, the flexible pipe being forcibly compressed between
the two conical parts as heretofore described, and the other end instead of having a
conical part is formed as a nut E which is tapped in its internal diameter to a suitable
size, to receive iron or any other kind of pipe as shown at F.

I GEORGE EMENS of Hetton-le-hole, in the County of Durham, Fitter, 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 is designed in order to simplify the ordinary methods of joining the
ends of hose pipes, or for connecting flexible tubes to metal tubes or fittings for
various purposes. The invention consists principally in dispensing entirely with the
ordinary methods of clamping or fastening by wire or other lapping materials the
ends of hose pipe to the respective parts of the coupling, and in so constructing and
arranging the various parts that the hose pipe itself forms the joint. Such being the
nature and object of my said invention, I will now proceed to describe the manner in
which the same is to be or may be performed or carried into practical effect, and in
order that the same may be distinctly understood, I have annexed to provisional
specification a sheet of drawings illustrative thereof and have marked the same with
figures and letters of reference, corresponding with those in the following explanation
thereof.
Figure 1 in the drawing shows in elevation the ends of two flexible pipes joined
together and made fast.
Figure 2 shows the same in section.
The joint consists mainly of a cylindrical part A screwed on its outer diameter to
receive the tapped ends of the nuts C and having at each end a plain conical part B of
smaller diameter to receive the hose pipe D.
The inside of the nut C is tapped at one end in the usual manner to fit the screw on
the outer diameter of A and the other end is formed into a conical part, slightly
rounded at its edges, having the same taper as the conical end B, the smaller
diameter of this part being sufficient to admit the hose pipe D, the pipe being
pressed on to the conical end B, and becoming thereby slightly expanded, the nut C
is then screwed on to the outer diameter of A, thus bringing the conical portion of the
nut in contact with the hose pipe D, thereby forcibly compressing the hose between
the two conical parts and forming a firm and perfectly tight joint.
Figures 3 and 4 show the arrangement by which a flexible pipe can be joined to
iron or any other kind of pipe, Figure 3 being in elevation, and Figure 4 in
section.
In this case one end of the cylindrical portion A, is formed in a similar manner to
that shown on Figures 1 and 2, the flexible pipe being forcibly compressed between
the two conical parts as heretofore described and the other end instead of having a
conical part is formed as a nut E, which is tapped in its internal diameter to a suitable
size to receive iron or any other kind of pipe as shown at F.

page_text: It will be evident that this construction of joint is equally applicable for joining
flexible hose on to fixed stand pipes, pumps or taps and for other similar purposes.
Having now. described the nature and object of my invention for improvements in
the construction of hose pipe couplings, together with the manner in which the same is
to be or may be performed or carried into practical effect, I declare that what I
claim is
The combination of inner and outer conical parts arranged as shown, brought into
forcible contact with the inner and outer diameter of the hose or flexible pipe, so that
the pipe is firmly compressed between the two conical parts thereby forming a
perfectly tight joint, the whole being constructed and arranged substantially in the
manner and for the purpose hereinbefore more particularly set forth and described.
Dated this 3rd day of June 1887.
