An Improved Hose Coupling.
Year: 1897

page_text: Date of Application, 7th May, 1897
Complete Specification Left, 20th Jan., 1898-Accepted, 5th Mar., 1898
I, CHARLES PREVET, of 48, Rue des Petites Ecuries, Paris, France, Manufacturer
of Preserved Provisions, do hereby declare the nature of this invention to be as
follows:
This invention relates to a hose coupling for connecting one length of rubber
hose to another or to a draw-off cock.
The invention is illustrated in the accompanying drawing wherein Figure 1 is
an external view and Figure 2 a longitudinal section of the hose coupling.
Figure 3 represents the coupling attached to a draw-off cock. The same letters of
reference denote like parts in all the Figures.
The coupling comprises an expansible spigot formed of a screw-threaded tubular
stem a provided with a head a and garnished with a sleeve b of rubber provided
with a flange the sleeve being confined between the head a and a cap c recessed
to receive the rubber flange the cap being slipped on the stem and pressed
towards the head a by a nut e screwing on the stem a¹ and acting through a
distance collar so as by the pressure to compress the tubular rubber sleeve b
longitudinally and expand it diametrically. The lower threaded end is screwed
into the bore of the rubber hose g which may be secured by a wire binding if
necessary, a washer f being interposed between the nut c and the hose g.
When the head a and sleeve of the coupling are inserted into a socket on
another length of tube or into the nozzle of a tap h, as in Figure 3, the nut c is
screwed up so as to expand sleeve b within the socket or nozzle and also press the
flange against the end of the socket or nozzle whereby a perfectly tight joint
is ensured and a thoroughfare for liquid is provided through the bore all of the
stem a¹.
An Improved Hose Coupling.
I, CHARLES PREVET, of 48, Rue des Petites Ecuries, Paris, France, Manufacturer
of Preserved Provisions, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a hose coupling for connecting one length of rubber
hose to another or to a draw-off cock.

page_text: The invention is illustrated in the drawing accompanying my Provisional
Specification wherein Figure 1 is an external view and Figure a longitudinal
section of the hose coupling. Figure 3 represents the coupling attached to a draw-
off cock. The same letters of reference denote like parts in all the figures.
The coupling comprises an expansible spigot formed of a screw-threaded tubular
stem a provided with a head a and garnished with a sleeve b of rubber provided
with a flange b', the sleeve being confined between the head a and a cap c recessed
to receive the rubber flange, the cap being slippeil on the stem a¹ and pressed
towards the head a by a nut e screwing on the stem a¹ and acting through a
distance collar d so as by the pressure to compress the tubular rubber sleeve b
longitudinally and expand it diametrically. The lower threaded end is screwed
into the bore a of the rubber hose g which may be secured by a wire binding if
necessary, a washer being interposed between the nut e and the hose g.
When the head and sleeve of the coupling are inserted into a socket on
another length of tube or into the nozzle of a tap h, as in Figure 3, the nut e is
screwed up so as to expand sleeve b within the socket or nozzle and also press the
flange against the end of the socket or nozzle whereby a perfectly tight joint
is ensured and a thoroughfare for liquid is provided through the bore all of the
stem a¹.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
A hose coupling consisting of an expansible spigot formed of a mushroom-
headed tubular serew-threaded stem communicating with the hose attached thereto,
a flanged india-rubber sleeve b' confined between the head a and a cap c loose
on the stem and recessed to receive the flange band a nut e screwing on said stem
and acting to compress the rubber sleeve longitudinally and expand it diametri-
cally so as to cause it to fit tightly in the bore of the nozzie or socket of the cock
or pipe to which it is to be connected and also compress its flange b' against the
end of the nozzle or socket substantially as specified.
