PROVISIONAL SPECIFICATION.
Improvements in Fittings for Hose or Tubing.
I, JAMES LIONEL JONES, of 15, Parliament Street, Dublin, Ireland, Hose
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in coupling the tail ends of hose or
tubing, and is especially applicable to that class of hose or tubing known as
wire bound," having an internal spiral wire body, as described in Letters Patent,
dated 19th day of June, 1884, numbered 9169; and dated 31st day of May, 1889,
numbered 9050 respectively.
"
By the term "tail ends," I mean that part of the fitting which is inserted
into the hose or tubing, and is, when so inserted usually bound or tied by some
suitable means.
In carrying out my invention, instead of scoring or notching the tail part of the
fitting I form round same a male screw thread of the same pitch as the spiral
wire on which the hose or tubing is made. This end then screws into the interior
convolutions of the wire forming the body of the hose or tubing.
As a modification I may reverse the arrangement, and on hoses or tubings having
an external wire form the tail part so as it will pass over the hose and screw on the
external instead of the internal wire spirals, these tails are preferably made to
taper slightly so that being screwed into the interior end the diameter increases,
and thus makes a perfectly staunch joint, or in the case of an external tail, the
diameter diminishes slightly, and thereby compresses, the hose and produces a
like effect.

Improvements in Fittings for Hose or Tubing.
I, JAMES LIONEL JONES, of 15, Parliament Street, Dublin, Ireland, Hose
Manufacturer, 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 coupling the "tail ends," of hose
or tubing and is especially adapted to that class of hose or tubing known as
wire-bound," that is provided with an internal spiral wire body and an external

spiral wire binding as described in Specifications dated 19th day of June 1884
numbered 9169. and dated 31st day of May 1889, numbered 9050 respectively
By the term tail ends I mean that part of the fitting which is inserted
into the hose or tubing and is when so inserted, usually bound or tied by some
suitable means.
In carrying out my invention, instead of scoring or notching the tail part of
the fitting I form round same a male screw thread of the same pitch as the
spiral wire which forms the internal body of the hose or tubing for which the
tail end is intended.
The fitting thus prepared then screws into the interior convolutions of the body
wire and makes a perfect air, and water tight joint.
As a modification I may reverse the arrangement and form a screw thread on
the internal circumference of the tail end so as to screw on over the external
spirals of the hose or tubing whereby a perfectly good air and water tight joint
may also be effected.
I prefer however the first described arrangement as being more convenient and
practical.
In order that my invention may be more readily understood, I attach the
accompanying sheet of drawings in which.
Figure 1 represents a piece of the special class of hose or tubing known as
"wire bound" and described in the above recited specifications respectively, and
in connection with which the improved fittings are designed for use:-the solid
spirals indicate the external wire binding and the dotted spirals the internal body
wire.
Fig. 2. represents an ordinary union coupling constructed according to my
invention, i.e., the tail ends are provided with male threads corresponding in
pitch to that of the convolutions of the internal body wire of the hose or
tubing.
Fig. 3 illustrates two pieces of hose or tubing (partly in section) coupled
together by my improved fitting.
Thus it will be obvious that according to my invention no special terminal or
preparation of any kind is necessary on the end of the hose or tubing in order
to receive the fitting, the tail ends being ready to engage direct with the con-
volutions of the wire body.
An important advantage therefore resulting from the use of my invention is
that a joint or coupling can be instantly effected at any part wherever the hose or
tubing may be cut.
From what has been described it will be readily understood how the modified or
converse arrangement above referred to may be effected:-that is providing the
tail ends with an internal screw thread instead of an external one, for engagement
with the convolutions of the external binding wire of the hose or tubing.
The tail ends are made, preferably to taper so that when screwed into the
interior of the hose or tubing the diameter of the fitting increases and when made
to screw on over the external convolutions of the hose or tubing the diameter of
the fitting diminishes.
By this means a perfectly staunch joint is ensured.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I desire to have it
understood that what I claim is :-
First: In the coupling or joining together the ends of hose or tubing of the
type referred to, the use and application of fittings provided with tail ends con-
structed and operating in the manner substantially as described and illustrated
in the accompanying drawings.
Second: The use and application of fittings provided with tail ends threaded
with a pitch corresponding to the pitch of the convolutions of either the internal
wire body or the external binding wire of hose or tubing known as
"
wire-bound"

page_text: so that such fittings may engage direct with the end of such hose or tubing and
thereby effect a perfectly staunch joint substantially as specified and illustrated
in the accompanying drawings.
