PROVISIONAL SPECIFICATION.
Improvements in Couplings for Hose Pipes, Rods, and the like.
I ISAAC ST. CLAIR GOLDMAN, of Redlands, in the County of San Bernardino,
State of California, United States of America do hereby declare the nature of
this invention to be as follows:-
The object of the invention is to provide a coupling for hose pipes and rods etc.
which is simple and durable in construction, permits of quickly and securely
fastening theparts without liability of leakage.
The invention consists in a recessed female head having a lip adapted to be
engaged by a hook formed on the other head and fitting into the said recess, and in
certain details.
The improved coupling is composed of two members adapted to connect with the
hose or formed or fastened on the rods to be connected. The male member is
formed with a head, preferably semi-circular, and fitting into a correspondingly
shaped recess formed in the female member. On the head and at the underside is
cut a transversely extending notch forming a hook adapted to engage a corre-
spondingly shaped lip extending transversely in the front end of the recess
of the female member. Into the recess fits a washer engaged by the surface
of the head and serving to form a tight joint to prevent leakage. The washer
preferably fits into an enlargement of the recess, the lower end resting against the
inside of the lip, while the upper end rests against a corresponding lip. Thus,
displacement of the washer is prevented.
On the top of the female member is secured a spring plate extending with its
free end onto the other member and engaging by a recess a projection or hook held.
on the latter member. The outer end of the spring plate is slightly curved upward
so as to form a convenient handle adapted to be taken hold of by the operator so
as to lift the plate out of engagement whenever it is desired to uncouple.
In order to prevent sidewise displacement of the spring plate, the latter passes
through a recess formed in the enlarged end of the female member.

Improvements in Couplings for Hose Pipes, Rods, and the like.
I, ISAAC ST. CLAIR GOLDMAN, formerly of Redlands in the County of San
Bernardino, and State of California, United States of America, Watchmaker, and
at present of No. 534, South Pearle Street, Los Angeles, California, aforesaid,
do hereby declare the nature of this invention and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in aud by the following
statement :-
The object of the invention is to provide an improved coupling for hose pipes.
rods, and the like, which is simple and durable in construction and permits of
quickly and securely fastening the parts in place without liability of leakage.
The invention consists in a recessed female head having a lip adapted to be
engaged by a hook formed on the other head and fitting into the said recess, and
also in certain parts and details and combinations of the same, as will be herein-
after described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a sectional side elevation of the improvement as applied to a hose.
Figure 2 is a plan view of the same.
Figure 3 is an end view of the male head.
Figure 4 is a similar view of the female head.
Figure 5 is a reduced side elevation of the improvement as applied on solid rods.
Similar letters of reference indicate corresponding parts in all the figures.
The improved coupling is composed of two members A and B adapted to connect
with the hose pipes C and D respectively or formed or fastened on solid rods C
and D as illustrated in Figure 5. The inale member A is formed with a head E
preferably made semi-spherical and fitting into a correspondingly shaped recess F
formed in the female member B. On the head E and at the underside is cut a
transversely extending notch forming a hook G adapted to engage a corre-
spondingly-shaped lip H extending transversely in the front end of the recess F
of the female member B. Into the recess F fits a washer I against which the
surface of the head E is pressed and serving to form a tight joint to prevent
leakage between the two members A and B. The washer I preferably fits into an
enlargement of the recess F in which it is retained by the lip H H as plainly
shewn in Figure 1 whereby the displacement of the washer is prevented. On the
top of the female member B is secured a spring plate J extending with its free
end on to the member A. and provided with a recess Jengaging with a projection
or hook K on the said member A. The outer end of the spring plate J is slightly
curved upwards so as to form a convenient handle J2 for lifting the said plate J
out of engagement with the projection K whenever it is desired to uncouple the two
parts. In order to prevent sidewise displacement of the spring plate the latter
passes through a recess B, formed in the enlarged end of the member B.
1 do not limit myself to any particular form or shape of the head E and the
corresponding recess or of the members A and B, as the said forms may be varied
according to the nature of the parts to be coupled together. A different locking
device, instead of the one described, may also be employed to hold, the two
members A and B in a locked or coupled position.
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-
1). A coupling, comprising a female section having a semi-spherical recess in its
end and provided with a lip, a male section provided with a semi-spherical head
fitting in the recessed end of the female section and provided with a rigid hook
engaging the lip of the said female section, and means for locking the two sections
together, substantially as described.
2). A hose coupling, comprising two members of which one is formed with a
recess and is provided at the front end of the said recess with a transversely
extending lip, the other member being formed with a hook adapted to engage the
said lip, its head fitting into the said recess and a washer fitted into the said recess
of one of the members to be pressed by the head of the other member to form a
tight joint, substantially as shewn and described.

page_text: 3). A hose coupling, comprising two members of which one is formed with a
recess and is provided at the front end of the said recess with a transversely-
extending lip, the other member being formed with a hook adapted to engage the
said lip, its head fitting into the said recess, a washer fitted into the said recess of
one of the members to be pressed by the head of the other member to form a tight
joint, and a lock for fastening the two members together, substantially as shewn
and described.
