sleeve 13 and terminates at that point, while
the thimble 20 extends inwardly beyond the
inner end of the female member 10 when in
operative position. The inner end of the
5 hose section 21 is disposed in the body por-
tion of the female member prior to the in-
sertion of the thimble 20. After position-
ing the hose section 21 as just stated, the
thimble 20 is inserted in the female member
10 and is expanded in any suitable manner to
force the. shoulder 21 of the thimble 20 out-
wardly and also to force the groove 19 of
the thimble 20 from the position shown in
Fig. 1 to that shown in Fig. 2, to provide
15 for a firm clamping of the inner end of the
hose section 21 between the ribs 22 and 23
of the female meniber 10 and thimble 20,
respectively, and also effectively provide for
a positive union between the female member
20 10, the sleeve 13, and thimble 20, preventing
accidental displacement of the latter. It
will thus be seen that the thimble'20 of the
female coupling member 10 not only co-
operates with the female niember to clamp
25 the -hose, but, by virtue of the groove 19
and shoulder 20, it also coperates with the
coupling sleeve 13 to reinforce the annular
shoulder 17 to hold the coupling sleeve in
true rotative position upon the female mem-
30 ber 10. Hence, besides performing the
function of a clamping thimble, the member
20 also performs the function of a swivel
element. It also presents its shoulder 21
to such cooperative relation with the shoul-
35 der 15 of the sleeve 13 as to provide a broad
bearing surface for the gasket 16.
The exterior of the sleeve 13 is provided
with grooves 24 to receive a wrench or any
other suitable implement (not shown) to
40 permit of ready operation of the sleeve to
draw the male and female members together
or disconnect them. If preferred, the exte-
rior of the sleeve 13 may be squared into
rectangular, hexagonal or other shape for
45 wrenching purposes in a manner well known
in the art, and which is thought too obvious
to illustrate.
From the foregoing, it will be understood
that the expansible thimbles taper from their
50 inner to their outer ends, in fact, in practice
they are formed almost into a knife edge
and at their outer ends they are quite thin.
It will also be understood that the expansion
of these thimbles occurs preferably at their
55 inner enlarged ends to expand the inner ends
of the hose positions considerably at their
inner extremities, but only slightly at the
points adjacent the outer ends of the coup-
ling. The result is that the fibers of the
60 hose are not broken by the expansion of the
thimbles at the outer ends of the latter, and
consequently weakeniing of the hose at the
outer ends, of the coupling is obviated.
Flexible hose when placed under heavy pres-
65 sure expands considerably, and even if thehose is not weakened by 'the expansion of
the thimbles, there is considerable friction
and consequent wear upon the hose at the
mouths of the coupling incident to expan-
sion of the hose and other strain thereupon, 70
and in many instances the hose eventually
breaks and leaks at the mouths of the coup-
ling. In the present instance, by virtue of
the thin outer ends of the thimbles and ex-
pansion thereof at their inner ends, and the 75
fact that the outer ends of the male and
female members are rounded, there is little,
if any, possibility of the hose being sub-
jected to undue wear at the mouths of the
coupling incident to heavy pressure or for 80
other reasons.
Of course my improved coupling is ap-
plicable to connect pipe sections as well as
flexible hose.
Having thus described my invention, what 85
I claim and desire to secure by Letters Pat-
ent is-
1. A hose coupling comprising a male
member, a female member composed of a
body portion and a sleeve, the body portion 9o
of the female member having an external
groove, a clamping thimble in each of said
members, the thimble in the female member
having a groove and also a shoulder, said
sleeve having shoulders, one shoulder for 95
engagement in the groove of the body por-
tion of the female member and the other
shoulder for engagement in the groove of
the thimble in the female member and adapt-
ed to overlap the shoulder of the thimble. 100
2. A hose coupling comprising a male
member, a female member composed of a
body portion and a sleeve, the body portion
of the female member having an external.
groove, a clamping thimble in each of said 105
members, the thimble in the female member
having an annular groove and also an an-
nular shoulder, said sleeve having annular
shoulders, one shoulder for engagement in
the groove of the body portion of the female 110
member and the other shoulder for engage-
ment in'the groove of the thimble in the
female member and adapted to overlap the
shoulder of the thimble in advance of the
latter. 115
.3. A hose coupling comprising a. male
member, a female member composed of a
body portion and a sleeve, the sleeve being
adapted to couple said members together,
thimbles in said members, said sleeve having 120
swiveled engagement with one of said mem-
bers and also having swiveled engagement
with the thimble in the female member to
hold said latter thimble against movement
outwardly of its member. 125
4. A hose'- coupling comprising a male
member, a female member composed of a
body portion and a sleeve, the body portion
of the female member having an external
groove, a tapering clamping thimble in each 1308
