ture of the character referred to having ‘a male section
adapted to connect with an end of a section of a com

to connect with the opposing end of another section of
the combined hose and loom.
A further object of this invention is to provide a
coupling of the character referred to wherein one of the
sections thereof carries releasable locking means to en- -
gage elements of the other section, which means includes

disconnect coupling adapted to make and break connec
tion between sections of a ?exible ?uid or gas conducting
hose, and between sections of an electric loom having a
plurality of electrical lines and extending parallel with 15
said hose.
The coupling that we’provide, while suitable for use
in many situations, is primarily intended for use in air
craft and more particularly in connection with a combi
nation oxygen supply hose and electrical loorn adapted
to supply oxygen to a pilot and to connect electrical or
electronic components carried by the aircraft and related
vcomponents carried on or by the person of the pilot.
In the past, it has been common practice to provide
terior of the said one section and adapted to be engaged

suitable automatic releasing means, as circumstances
require.
Another object of ‘our invention is to provide a struc-'
ture of the character referred to wherein accessibility and
operation of the actuating sleeve is not impeded by the
loom ‘and wherein the loom and electrical parts and/ or
portions of the structure are independent of and are in
no way affected by operation of the said locking means.
An object of our invention is to provide one embodi

When the male member 18 is engaged in the body 40
of the female section, its inner end engages the sleeve 59
wardly from the inner surface 48 of the head and adapted
to slidably enter the opening 31 in the head '19 of the
male section and to oppose the inner surface 67 of the
carrier 63 when the coupling is made up. The carrier
64 is further provided with an inwardly opening recess
74 entering its inner end and adapted to slidably receive
the boss 68 on the carrier 63 when the coupling is made
and urges the sleeve longitudinally outwardly in the female
section and against the spring 60.
When the balls are released to shift radially outwardly
and the male member is withdrawn from engagement in
the female section, the sleeve 59 follows the male mem
her to a point where it overlies the openings 55 and holds
the balls 56 out and the ring 57 and actuating sleeve 57'
in their actuated position, as clearly illustrated in FIG. 3
of the drawings.
It is extremely important to note that the wedge ring
57 is slidably engaged in the actuating sleeve 57’ and
that the spring 58 is engaged between the ring and the
sleeve to normally urge the ring longitudinally inwardly
in the sleeve. With this relationship of parts and when

With our new construction, it will be apparent that the
operator, or pilot, when making connection with the
oxygen supply system and electrical system of the air
craft need only concern himself with one simple opera

wishes to ‘break the connections, he need only engage
