COMPLETE SPECIFICATION.
Improvements in Hose or Tubing Connectors.
I, JOSEPH BEST GREEN, of Janesville, in the County of Rock and State of
Wisconsin, United States of America, 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 a new means for connecting together two ends of hose,
or other flexible or ductile tubing, or for uniting such hose or tubing with a
hydrant, or a nozzle; also serving as a mender. It is simple in construction,
aud provides an absolutely water, air, gas, and steam tight joint, which is
capable of withstanding so severe a strain, that it may be said to be practically
impregnable.
My said device consists of a cylindrically shaped piece which is provided
exteriorly at oue or both ends with one or more annular shoulders, which each
taper toward their contiguous cylinder end. Said cylindrical piece is forced into
the end of a hose or other flexible or ductile tube, so that the prominent edges of
its shoulders become somewhat embedded therein. A thimble shaped substantially
as the frustum of a cene, having a screw thread on its interior surface, and having
a flaring mouth, is then screwed upon the hose end, causing the material of said
hose or tubing to be forced into the interstices between the cylinder and its
shoulders, and thus a perfect grip is established which cannot be released except
by unscrewing said thimble.
In order that my said invention may be better understood and explained in
detail, I have annexed hereto a sheet of drawings, in which:
Fig. 1 is a side view showing two ends of tubing united by my connection.
Fig. 2 is a central longitudinal section of Fig. 1 showing both inner and outer
portions of my connector.
Fig. 3 is a side elevation, partly broken away, being a detail of the thimble, and
showing its formation.
Fig. 4 is a front view of said thimble.
Fig. 5 is a detail side view of the cylindrical connector piece, and
Fig. 6 is a detail side view of a connector for uniting a hose end with a
nozzle &c.
In Figs. 1 and 2 I have illustrated two pieces of hose A and A¹ which have been
united by my device. Said device comprises a cylindrical piece B which is prefer-
ably formed of metal, and which is provided at either end with the exterior
annular shoulders a a. I do not limit myself to the specific number of shoulders a
shown as may on occasion use only one, or a plurality, but I have shown two of
such shoulders as being a convenient number for the purpose. Said shoulders a
taper towards their contiguous end 6 of the cylinder, as will be seen, and between
each pair of said shoulders as also between the rear shoulder and the surface of the
cylinder, annular spaces or interstices c are formed.
An end of said cylindrical piece B is fitted into the end of tube A, so that the
laterally extending edges of shoulders a become slightly imbedded in its substance.
C indicates a collar or thimble piece which is formed substantially as the frustum
of a cone, and is provided, at its major diameter, with a flaring or bell-shaped
mouth d. Said thimble C is screw-threaded interiorly, and has one or more
(preferably two) ribs e upon its outer surface, said ribs extending in a line
co-incident with the conical structure of said thimble, and serving as a means for
gripping and turning it.

page_text: Thimble C is passed, with its mouth d foremost, over cylindrical piece B and
the end of hose A, (upon which it is arranged to fit snugly) and it is screwed
upon said hose end, over the shoulders a.
The bell-shaped or flaring mouth d of the thimble C enables it to pass readily
over the bose end, even though the same be ragged or uneven, and by this
particular construction of thimble no time is lost in making the connection. The
forward movement of the thimble in screwing upon the hose end is further
facilitated by its conical formation, and, as it thus advances, it presses the material
of the hose between it and the piece B, into the spaces e, behind shoulders a until
the jointure is made effective.
When the aforesaid couplings have been applied to the ends of two adjacent
pieces of hose or the like, as A, A', to connect same, it will be found that the
greater the tension applied to said pieces, to sever them, the more complete will
become their union. In fact, they can only be parted by first unscrewing the
thimble C.
It is unnecessary for me to dilate upon the various uses to which this device can
be applied, being sufficient to enumerate the following uses, to wit:
For uniting or mending breaks in hose, tubing of all sorts and descriptions, lead
and other ductile pipe, and for connecting the above with hydrants, nozzles, &c.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. A hose or tubing coupler, consisting of a cylindrical piece arranged to fit
within an end of each of two pieces of hose or tubing, and a thimble arranged to
screw upon said hose or tubing to bind said cylindrical piece and the tubing
together.
2. In a hose or tubing coupler, a cylindrical connecting piece arranged to be
inserted part way within a hose or tubing, means upon said connecting piece to
engage with said hose or tubing, and means for binding said parts together.
3. A coupling for hose or flexible tubing comprising a cylindrical connecting
piece arranged to fit part way within said hose or tubing, said connecting piece
having one or more annular tapering shoulders formed thereon, and a collar or
thimble arranged to fit over said hose or tubing, and to embed and bind said
hose or tubing in the interstices formed behind the shoulders on said connecting
piece.
coupling for hose or flexible tubing, a cylindrical connecting piece
arranged to fit part way within said hose or tubing and baving means of engage-
ment therewith, together with an interiorly threaded collar or thimble shaped
substantially as the frustum of a cone, and being outwardly flared at its major
diameter, substantially as and for the purposes set forth.
