I, AUGUST WILHELM BILLMAN, of 24 Müster Samuelsgatan, Stockholm, in the
Kingdom of Sweden, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a hose-coupling composed of two symmetrical halves or
sections and has for its purpose to so arrange these halves that they can be
instantaneously coupled together or disconnected, while their interlocking action is
assisted by the water pressure in the hose, making the joint more perfect the more
said water pressure is increased.
Each section is provided at its head end with two lugs projecting diametrically
opposite each other over the said end of the section. A latch is arranged in one of
these lugs so as to be movable almost tangentially to the circumference of the
coupling, and against this latch beara one arm of a bell-crank lever fulcrumed on the
lug while its other arın enters into an opening through the wall of the section and
is forced outward by an elastic ring which is inserted in the mouth of each section,
just inside the bell-crank lever and serves as a packing ring when the two sections or
halves of the coupling are united. The other lng on each section is provided at one
eud with an aperture located so as to allow of the latch of the other section or half
snapping into it when the two sections are pushed together. In order to facilitate
the snapping of the latches their ends should be inclined with reference to the axia
of the coupling. For disconnecting the coupling the handles of the two latches are
pulled simultaneously, this action releasing the latches from the corresponding
apertures, and the sections or halves of the coupling are subsequently pulled apart.
When the halves are united, the pressure of the water in the hose will act on the
elastic ring in each section and said rings being thereby expanded will force the
inner arms of the bell-crank levers outward and inasmuch as the latches are pushed
into the apertures with greater force the higher the water pressure a firm engagement
of the two halves or sections of the coupling will be effected and all danger of
accidental disengagement avoided.
I, AUGUST WILHELM BILLMAN, of 24 Mäster Samuelsgatan, Stockholm, in the
5 Kingdom of Sweden, Manufacturer, do hereby declare the nature of this invention
and in what manuer the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

page_text: My invention relates to a hose-coupling composed of two symmetrical halves or
sections and has for its purpose to so arrange these halves that they can bo
instantaneously coupled together or disconnected, while their interlocking action
is assisted by the water pressure in the hose, making the joint more perfect the
more the said water pressure is increased.
In the accompanying drawing I have shown a hose-coupling arranged in accordance
with this invention.
Figure 1 illustrates a side view of the two symmetrical halves or sections of the
coupling joined together.
Figure 2 is an end view of one of these sections and
Figure 3 is a similar view partially in cross-section illustrating the position of the
coupling latch during the operation of connecting or disconnecting the sections.
Each section is provided at its head end with two lugs b, c, (Figure 2) projecting
diametrically opposite each other over the said end of the section. A latch dis
arranged in the lugs b so as to be movable almost taugentially to the circumference
of the coupling, and against this latch bears one arm of a bell-crank lever e, e',
Fulcrumed on the lug while its other arme enters an opening through the wall of
the section, and is forced outward by an elastic ring which is inserted in the mouth
of each section, just inside of the bell-crank lever and serves as a packing ring
when the two sections or halves of the coupling are united. The other lug c of
each section is provided at one end with an aperture g located so as to allow of the
latch of the other section or half snapping into it when the two sections are
pushed together. In order to facilitate the snapping of the latches their ends
should be slanted with reference to the axis of the coupling. For disconnecting
the coupling the handles h of the two latches are pulled simultaneously, this action
releasing the latches from the corresponding apertures g (Figure 3), and the sections
or halves of the coupling are subsequently pulled apart. When the halves are
united, the pressure of the water in the hose will act on the elastic ring f in each
section and said rings being thereby expanded will force the inner arms of the
bell-crank lever outward and, inasmuch as the latches are pushed into the apertures
with greater force the higher the water pressure a firm engagement of the two
halves or sections of the coupling will be effected and all danger of an unintentional
disengagement avoided. A spring may be arranged to act upon each latch for
pressing it forward.
Having now particularly described and ascortained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
clain is :-
An improved hose-coupling composed of two symmetrical sections or halves (a, «),
each provided at its head end with two axially projecting lugs (b, c), (diametrically
opposite each other, one of said lugs (b) having a latch (d) inovable through it
almost tangentially to the circumference of the coupling and this latch being acted
upon at its rear end by one arm (e) of a bell-crank lever (e, e) which is fulcrumed
parallel to the axis of the coupling and whose other arm (e¹) protrudes to the inside
of the half or section and is forced outward by means of an elastic ring (f), inserted
in the mouth of said section; while the other lug (c) is provided with an aperture (g)
into which the latch of the other half or section snaps when the two sections are
pushed together.
