PROVISIONAL SPECIFICATION.
An Improvement relating to Hose Pipe Couplings.
We, WILLIAM CORNISH, of 1, Albert Terrace, Fowey, Cornwall, Master
Mariner, and ALEXANDER SMART, of 24, Spring Vale Place, Saltcoats,
Ayrshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
:܃
This invention relates to coupling hose pipes to water mains, and consists in the
provision, in the main, of a valve at each coupling place; the valve being so
arranged that the act of coupling opens the water-way from the main to the hose,
and is closed by the act of uncoupling. By this provision the water need not be
turned off from the main for coupling; and coupling caps and plugs are dispensed
with.
Screwed into a neck projecting outwards from the water supply pipe or main is
a valve seating upon which, when no hose is coupled, rests a valve the spindle of
which is passed through a bracket in the seating.
The water in the supply pipe normally keeps the valve on its seat. The valve
spindle projects outwards beyond the seating. In screwing up the union nut to
connect a hose to the supply pipe or main, a bar extending across the hose pipe is
brought into contact with the projecting end of the spindle and the valve is raised
admitting water, to the hose pipe.
As the union nut is unscrewed for disconnecting the hose pipe, the valve closes.
The valve may, when in positious which render it desirable, be acted upon
by a spring which tends constantly to return it to its seat.

An Improvement relating to Hose Pipe Couplings.
We, WILLIAM CORNISH, of Albert Terrace, Fowey, Cornwall, Master Mariner,
and ALEXANDER SMART, of 24, Spring Vale Place, Saltcoats, Ayrshire, Engineer,
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:-
This invention relates to coupling hose-pipes to water mains, and consists in the
provision, in the main, of a valve at each coupling place; the valve being so
arranged that the act of coupling opens the water-way from the main to the hose,
and is closed by the act of coupling. By this provision the water need not be
turned off from the main for coupling; and coupling caps and plugs are dispensed
with.
Screwed into a neck projecting outwards from the water supply pipe or main is
& valve-seating upon which, when no hose is coupled, rests a valve, the spindle of
which is passed through a bracket in the seating.

page_text: The water in the supply pipe keeps the valve on its seat. The valve spindle
projects outwards beyond the seating. In screwing up the union nut to connect a
hose to the supply pipe or main, a bar extending across the hose pipe is brought
into contact with the projecting end of the spindle, and the valve is raised
admitting water to the hose pipe.
As the union nut is unscrewed for disconnecting the hose pipe, the valve closes.
The valve may, when in positions which render it desirable, be acted upon by
a spring which tends constantly to return it to its seat.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 thereon
represents, in section, the improvement relating to hose-pipe couplings which
constitutes this invention. The valve is shown closed. Fig. 2 is a similar view
showing the hose-pipe connected and the valve open.
Screwed into the neck a of the water supply pipe or main b is a valve-seating o
upon which when, as seen at Fig. 1, no hose-pipe is connected, the valve d rests
closing communication between the throat e of the valve-seating and the pipe b.
The spindle d¹ of the valve d passes through a socket o from which extend at
suitable distances apart radial arms c between which are clear spaces after the
manner of the spaces between the spokes of a wheel. The face of the valve d
bearing on the seating c is a washer of india-rubber, leather, or other suitable
substance. The spindle of the valve projects beyond the outer end of the
nipple f. In screwing up the union nut g, Fig. 2, to connect the hose-pipe / to the
supply pipe b, the bar which extends across the mouth of the hose-pipe his
brought into contact with the lower end of the spindle d' and by this means the
valve d is raised from its seat and continues to rise until the union nut g is fully
screwed on the nipple f. Communication is thus established between the main
pipe 6 and the hose-pipe h.
As the union nut g is unscrewed to disconnect the hose-pipe h, the valve is
lowered and ultimately returns to its seat.
The relief valve usually employed in connection with water service pipes is
adopted in connection with this invention. The form of valve may vary and is not
restricted to that shown in the appended drawings.
When the valve is reversed or in other positions which render it desirable,
it may be acted upon by a spring which tends constantly to return it to
its seat.
Caps. or plugs are dispensed with, communication between the main and the
hose-pipe is readily made and without escape of water, and the water supply in
the main need not be turned off when shifting the hose-pipe from one section of
the main to another. O
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A method of, and means for coupling and uncoupling hose-pipes, and establishing
and cutting off communication between them; consisting of a valve controlling
the communication between the main and the hose-pipe, such valve being arranged
to open into the main by the contact of a bar extending across the mouth of the
hose-pipe with the valve spindle as the union nut is screwed on the nipple of the
branch, and to return to its seat as the union nut is unscrewed, substantially as
hereinabove described with reference to the accompanying sheet of illustrative
drawings.
