vThe present invention relates to hose couplings
and more particularly to aquick detachable cou
pling for releasably connecting hose lines trans
mitting fluids under vacuum or moderate pres
mounted in a groove II in the socket in position
to bear on the portion 3 of the'nipple when thel
coupling is assembled.
Releasable locking means for holding the cou-Y
pling in assembled relation is provided >in the
Various types of quick detachable hose cou
plings have been developed and found commer
cial vacceptancebut such couplings have in gen
eral been more or less specializedl in character
10 in accordance with the type of installation in
which they are employed. In particular there is
a lack of commercial couplings of this type which
are interchangeably adaptable for use with con
duits for either vacuum or moderate pressure.
It is an object of the present invention to pro
vide a novel quick detachable hose coupling which
is'simpie and economical in construction and ef
iicient and reliable in operation.
It is another object to provide such a_ device
20 which is readily operable by very simple manipu
lation, requiring no twisting or rotation of any
Another object is to provide such a device which
is equally well adapted for use in vacuum lines
and in lines carrying moderate positive pressures.
Further objects and- advantages will be ap
parent from the following description taken in
connection with the' accompanying drawing in

periphery of the socket and provided with lateral
1y extending portions I6 and I’I adapted to seat
in a circumferential- groove I8 in the socket so as
to prevent longitudinal withdrawal of the locking
.clip from the socket.
A thimble I9 is arranged to bear loosely on the
periphery of the socket, having a ñange 2| at
its outer end provided with an opening 22 to
receive the nipple, and a ñange 23 at its inner
end arranged to project dntov a circumferential
groove 24 in the periphery of the socket, the width
of the groove 24 being sufficiently greater than
the thickness of the ñange 23 to permit limited '

Referring ñrst'to Fig. 1 of the drawing, there
is illustrated a spud or nipple I having a'cylin

diameter adjacent its end, the step „between the
two surfaces being defined by a beveled shoulder

In the operation of the device, introduction of
the nipple into the socket as illustrated in Fig. 3
causes the locking clip I2 to straighten up sufiì

whereupon the cylindrical portions of the‘fnipple
enter the corresponding portions of the socket,

from the socket is then prevented by the clamp'
