An Improved Pipe and Rod Coupling, Part of which is applicable
as a Nozzle.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-.
My invention relates to an improved means for expeditiously and firmly uniting
sections of pipe, hose or solid rod, so as to allow them to be readily detached when
desired.
In the accompanying drawing,
Fig. 1 is a perspective view of the two parts, male and female, of the coupling,
when separated, the locking lever of the female part being thrown back.
Fig. 2 is a perspective view of the two parts, as first brought together for
coupling.
Fig. 3 is a longitudinal section of the two parts connected.
Fig. 4 is a perspective view of the locking lever.
Fig. 5 is a perspective view showing a modification, the two parts of the
coupling being separated.
Similar letters and figures of reference indicate similar features in the respective
figures.
The male and female parts of the coupling are represented by A and B,
respectively, the first named being designed to receive the other, when the sections
of pipe, hose, etc., to which the parts are joined or form a part, are to be connected.
The part A, of the coupling, the general form of which is cylindrical, is provided
upon its main portion with ribs a, to assist in retaining it within a tubular hose
when covered, or wrapped by wire or the like. The opposite end 1 of said part A,
is of enlarged diameter, producing a socket with an internal shoulder b, upon
which a leather or gum washer c is seated. A sufficient proportionate length is
given to the socket portion 1; and on its exterior is formed an ear d, to which the
locking lever C is pivoted at c'. A segment of the annular edge of the socket
portion is removed, as at 2. The locking lever C is provided with a forked
inner end, composed of two sides 3-3; the inner of which is extended
beyond the pivot, and formed into a cam or wedge 4 which, in the movement
of the lever C upon its pivot, enters the opening 2, for a purpose hereinafter
described.
The main portion of the male part B of the coupling is also furnished with
ribs a', similar to those a of the part A. The part B is also substantially
cylindrical in form, it having, near its inner end, a flange g against which the end
of the attached pipe or hose section fits; and having, outside of said flange g, an
annular groove h and a rounded head i. It will be observed that the socket
portion of the part A of the coupling, is, preferably at the point opposite the
pivot c¹ of the lever C, provided with a shoulder 5, and that the edge of

page_text: the socket, across the length of said projection, is inclined or beveled back,
as at 6.
In order to unite the two parts A and B, it being supposed that each is
attached to a section of pipe, hose, etc., the two parts are first brought, sub-
stantially, to the position shown in Fig. 2, the inner surface of the rounded head i
of the part B being placed over the shoulder 5 of the part A, so as to rest within
the depression 5", between said shoulder 5 and the washer c. It will be seen that
the inclined or beveled portion 6 allows the bringing together of the parts at such
angle as will permit the head i to fit over the shoulder 5. At this time, the locking
lever C is thrown back, so that its cam or wedge 4 is elevated above the upper
portion of the back edge of the head i; and, in order to continue the operation of
coupling, the part B must now be pushed or tilted inward by hand, so that the
rounded face of its head i shall fit up, in a measure, against the washer c, so that
the back edge of said head shall be brought forward of the point or narrowest
part of the cam or wedge 4 of the locking lever C. This being the position of
the two parts of the coupling, the part B will still stand at a slight angle with
reference to a line drawn longitudinally through the part A. In order to complete
the coupling action, the lever C must now be pushed down by the finger or thumb
of the operator, so that the cam or wedge 4 thereof shall press against the back
edge of the head i and gradually draw in the rounded exterior of the head against
the washer c, and, at the same time, the outer face of the flange g against the
trued outer edge of the socket portion 1 of the part A. The two parts of the
coupling have now been brought to the position shown in Fig. 3, a perfect union
having been effected. The compression of the washer c by the rounded head i
insures a perfectly water or air tight joint.
In Fig. 5, the same construction of parts is retained, and the same mode of
coupling carried out, the only difference between the devices shown in said figure,
and in Figs. 1 to 4, inclusive, being that the female part of the coupling is threaded,
exteriorly, to adapt it to be screwed into a pipe, hose, etc., and the male part
provided with an internal thread 7 to fit it to screw upon the pipe, hose, etc.
The
part B, when used with a pipe or hose, may, when detached from the part A, be
used as a nozzle or tip, for watering or sprinkling purposes.
It is obvious that by slight mechanical changes in form, not involving invention,
the parts A and B may be adapted for use with metal tubing or solid rods, such as
shafting or pump rods; or the said coupling parts may be formed integrally there-
with, if desired, and thus afford reliable means for the expeditious securing of tube
or rod sections end wise; such modifications in form and use being manifestly within
the scope of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
:
1. In a coupling, the female member thereof having a segmental opening in its
edge and provided with an ear and a lower shoulder, the edge of said member
being inclined or beveled back across the front of 'said shoulder, combined with a
locking lever pivoted to said ear, and having a cam or wedge adapted to enter said
segmental opening, substantially as set forth.
2. In a hose coupling, the combination of a male section having a head and an
annular shoulder, a female section having on its edge a shoulder or lip, the edge of
said female section being inclined or beveled back across the front of said shoulder,
said female section also having an edge opening opposite said shoulder or lip, and a
lever, provided with a cam or wedge, pivoted to the female section in its edge opening
and adapted to engage the annular shoulder of the male section, substantially as
set forth.
3. In a hose coupling, the combination of a male section having a head and an
annular shoulder, a female section having on its edge a shoulder or lip, the edge of
said female section being inclined or beveled back across the front of said shoulder,

page_text: said female section having also an edge opening opposite said shoulder or lip, a
lever, provided with a cam or wedge, pivoted to the female section in its edge
opening and adapted to engage the annular shoulder of the male section, and a
washer placed between said coupling sections; the construction being such that, in
uniting the two sections, the said inclined or beveled edge shall allow the shoulder
of the male section to be hooked over the shoulder or lip of the female section and
afterwards brought with its face parallel to the face of the female section ready
to be drawn into tight engagement therewith by the wedge-like action of the locking
lever, substantially as set forth.
