I, WILLIAM DAVID PATTERSON, of 14 North 5th Street, Keokuk, in the
County of Lee and State of Iowa, United States of America, Attorney-at-Law,
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:—
Figure 1 is a longitudinal section of my improved hose-coupling.
Fig. 2 is a transverse section taken on line 22 in Fig. 1, showing the coupler
closed; and
Fig. 3 is a transverse section on the same section-line, showing the coupling
released.
Similar letters of reference indicate corresponding parts in all the views.
The object of my invention is to produce a simple and efficient coupling for
connecting lengths of hose, which may be connected instantaneously and readily
disconnected.
My invention consists in a coupling formed of an outer and inner portion, the
outer portion being provided with a circumferential groove containing a movable
ring, and spring-actuated latches pivoted in the outer portion and adapted to enter
an annular groove in the inner portion, the said latches being connected by links
with the ring of the outer portion, so that by turning the ring the latches may be
withdrawn and the inner portion released, all as will be hereinafter more fully
described. The outer portion A of the coupling is bored in two diameters, con-
nected by a conical portion a and a shoulder b. An elastic packing c rests upon the
shoulder b. The larger part of the outer portion A of the coupling is furnished
with a collar d, formed integrally with the coupling, and a collar is screwed
on the coupling. Between the collars d d¹ is a groove e, in which is placed the
ring B.
In diametrically-opposite sides of the part A and opposite the groove e are
formed mortises f, in which are pivoted the latches, which are oppositely
arranged with respect to each other. The said latches gare pressed forward by
spiral springs h, and the outward movement of each latch is limited by a link i,
pivoted in a recess ; in the ring B, and also pivotally connected with the free end
of the latch g.
In one side of the portion A of the coupling is formed a recess a¹, between one
end wall of which and a lug b', projecting from the ring B into the recess, is
held a spiral spring a², which spring normally acts to hold the ring B in the
position shown in Fig. 2. The ring B is furnished with lugs k, located over the
recesses, which lugs are adapted to receive a spanner or wrench for turning
the ring.
The inner portion C of the coupling is furnished with a circumferential groove
for receiving the latches g g'. The inner end of the part C is provided with a
bevelled surface m, and the outer end is reduced in diameter to receive the hose.

page_text: The free ends of the latches are bevelled on their outer edges for engagement
with the bevelled surface m of the part C, so that when the part C is inserted in
the part A the latches will be pushed back and will drop into the groove / in the
inner portion of the coupling. To release the coupling the ring B is turned,
thereby causing the latches gg to be drawn outwardly by means of the links i and
the spring a to be compressed, as shown in Fig. 2, whereupon the part may be
drawn out, the spring a² then reacting and causing the ring to assume the position
shown in Fig. 2.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. A coupling formed of two parts, one part being furnished with the spring-
pressed latches ga', the spring-pressed ring B, and links i, the other part being
grooved circumferentially and adapted to receive the spring-pressed latches,
substantially as specified.
2. A coupling formed of the parts A. C, the part A being furnished with the
collars d d', the spring-pressed latches, pivoted in mortises in the part A,
the spring-pressed ring B, placed between the collars d d', and the links, pivoted
in the ring B and connected with the latches y g', substantially as specified.
