COMPLETE SPECIFICATION.
Improvements in Fittings for Hose and like Pipes."
I, ADAM MCKEE, of No. 246 New York Avenue, in the town of Union Hill,
Hudson County, State of New Jersey, United States of America, Plumber, 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:
-
The invention relates to Improvements in Hose Fittings and pertains particu-
larly to means applicable either to the nozzle or the coupling for the hose, as
well as to devices for coupling two pieces of hose together or for mending the hose.
The invention pertains particularly to the neck portion of the hose fitting,
which portion enters the hose, and said invention consists in the novel features
hereinafter described and particularly pointed out in the claims..
Referring to the accompanying drawings, forming a part of this application:
Fig. 1 is a central, vertical, longitudinal section through a section of hose
provided with a coupling constructed in accordance with and embodying the
invention, said coupling being also in section;
Fig. 2 is a side elevation of a hose coupling embodying the invention, this
coupling being intended for securing two pieces of hose together or for mending
the hose and being double ended or having two corresponding necks, as shown;
Fig. 3 is a vertical transverse section on the dotted line 3-3 of Fig. 1; and
Fig. 4 is a like section on the dotted line 4-4 of Fig. 1.
In the drawings, referring to Figs. 1, 3 and 4, A designates a section of hoze
and B the coupling at the end thereof, said coupling comprising the usual
internally threaded sleeve C and the neck D, which neck embraces the features
comprising the present invention. At one end of the neck 1) is formed the
annular shoulder E and adjacent to said shoulder E there is formed upon the
neck D the annular shoulder F between which and the annular shoulder G
formed on said neck is a broad annular groove H within which is placed the sheet
metal band I snugly filling said groove H and formed from a strip of sheet metal
whose ends are correspondingly cut on a diagonal line, as shown at J, and whose
entire surface is covered with the prongs K punched out from the sheet metal and
extending outward on inclined lines toward the end of the hose A. The band
I is wrapped around the neck ]) between the annular shoulders F, G, and until
the neck D has been driven into the hose A the diagonal edges J of said band I
will be slightly free of one another, as shown at the left hand side of Fig. 2,
whereas, upon the said neck D being driven into the hose the pressure of the
latter will bring the said diagonal edges J substantially together, as indicated at
the right hand side of Fig. 2. The inner end of the neck D beyond the annular
shoulder G is formed with the coarse grooves L having inclined sides extending
outward toward the end of the lose and upon the inner end of the neck is placed
the tight fitting band M of rubber or like material which at its outer edge engages
the said shoulder G, the latter acting as a stop for said band M. The band M is
of greater thickness than the shoulder G and is of such length that its end projects
into the hose beyond the end of the neck 1). The purpose of the band M is to
prevent leakage around the neck 1) when the latter is within the hose.

page_text: The form of coupling illustrated in Figs. 1, 3 and 4 is adapted for connecting
the. hose to the usual water supply pipe, the latter being threaded to engage the
threaded sleeve C held upon the neck D by means of the shoulder E at the outer
end of said neck. The sleeve C 18 slipped upon the neck D from the inner end
thereof before the band M, and, preferably the sheet metal band E, are applied
thereto.
The sheet metal band I made from a flat strip is wrapped around the neck D
between the shoulders F, G, which act as stops for the ends of the band and sai
band I when in position constitutes a snug sleeve encompassing the neck D but
capable of turning thereon. The band constitutes an enlarged elongated
washer which is aided in being retained in position upon the end of the neck D
by means of the annular grooves 1 and shoulder G. When the neck D is forcibly
pressed into the end of the hose A, as shown in Fig. 1. the band M will firmly
bind against the inner surface of the hose and the external surface of the end
of the neck 1) and the prongs K of the band I will engage the inner surfaces of
the end of the hose and securely retain the latter upon the neck D. There is a
substantial advantage in employing the band I-having the prongs K in that the
prongs will securely engage the nose and the band will permit the hose to turn
upon the neck D in instances in which the hose may be twisted prior to the
pressure of water being turned into the same. The pressure of the water will
frequently be sufficient to force the hose and band I to turn together upon the
neck and thus relieve the hose from its twisted condition.
The form of the invention shown in Fig. 2 is substantially a duplication of the
device illustrated in Fig. 1, less the coupling sleeve C, and the construction shown
in Fig. 2 is intended for use in coupling two pieces of hose together, as for
instance, in mending hose or adding a further length thereto.
The con-
In Fig. 2 at the center of the coupling is an annular shoulder N and at each
side of this shoulder is provided a neck D corresponding in construction with the
neck D of Fig. 1, and the parts of which are lettered correspondingly with the
parts of Fig. 1 and require therefore no further detailed description.
struction shown in Fig. 2 duplicates the neck D of Fig. 1 in order that the neck
at one side of the shoulder N may enter one section of the hose A while the neck
at the other side of the said shouider N may enter the other section of hose A.
At the right hand side of Fig. 2 the hose is shown by full lines in position upon
the neck D while at the left hand side of Fig. 2 the section of hose is indicated
by dotted lines and the sheet metal band I is shown in the condition it has prior
to having its edges squeezed together by the pressure of the hose applied theron.
When the neck D of the hose fitting is forced into the end of the hose the latter
will be rigidly retained thereon and will not require any external wrapping to
bind it upon said neck.
Haying 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. In a hose fitting, the neck D having the band or washer M at its inner end
and provided with the annular groove H, combined with the band I applied
within said groove and having the prongs K inclined outward toward the end of
the hose; substantially as set forth.
2. In a hose fitting, the neck D having at its inner end the grooves L and
provided with the annular groove H and shoulders F, G, combined with the band
or washer M engaging said grooves I and the sheet metal band I applied within
said groove H between the shoulders F, G, and having the prongs K struck up
therefrom and inclined outward toward the end of the hose; substantially as set
forth.
3. In a hose fitting, the neck D having at its inner end the band or washer M,
combined with the sheet metal band I encompassing said neck and capable of

page_text: turning thereon, said band having struck up prongs K inclining outward toward
the end of the hose; substantially as set forth.
4. In a hose fitting, the neck baving the groove H and shoulders F, G, com-
bined with the washer or band M at the inner end of said neck and the sheet
metal band I applied within said groove H, said band having the diagonal end
edges and also the prongs K struck up therefrom and inclining outward toward
the end of the hose; substantially as set forth.
5. A hose fitting having the central annular shoulder N and the neck D at each
side of said shoulder, said necks corresponding with one another and each having
an annular groove, combined with the washer or band M at the end of each of
said necks, the shoulder G at the outer end of each washer or band and the sheet
metal band I applied within the groove formed between the shoulders N, G, and
having the prongs struck up therefrom and inclining outward toward the end of
the hose; substantially as set forth.
6. In a hose fitting, the neck 1) to enter the hose, combined with the sheet
metal band I encompassing and adapted to turn with the hose on said neck, the
surface of said band having the series of prongs struck up therefrom and inclining
outward toward the end of the hose; substantially as set forth.
