INGLIS ROSS 19 South St. James Street Edinburgh in the County' of Midlothian
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to Ball Hydrants or water service valves for extinguishing
fires and for serving and leading water off from main. supply pipes for other useful
purposes The top or cover of this valve chest is made separate and secured fluid
pressure tight by snugs and screw bolts. jointing the under face surface on that of the
upper edge by a vulcanised rubber ring which forms, the valve scat. The nature and
novelty of this invention consists as follows:-By an important improvement the
vulcanite ball which forms the valve is secured to its seat by a cup and spiral spring
made of steel and coated with tin the spring being inserted in a recess in the valve
chamber under the vulcanite ball the spring being made longer than the depth of the
valve chamber so as to make it fluid tight with the spiral spring without the use of
water. By this arrangement it prevents any stagnant water or gas which sometimes
accumulates in the surface-box from entering the main pipe when the water is
turned off.

page_text: I INGLIS ROSS of Number 19 South St. James Street Edinburgh in the County of
Midlothian 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 is of the nature of an improvement in the working of Ball Hydrants
or water service valves for serving and leading off water from main supply pipes for
shuch purposes as extinguishing fires and for other uses where a considerable supply
and force of water is required.
The cover of the valve chest is of a separate piece made fluid pressure tight by
snugs and screw bolts and its under face surface consists of a vulcanite rubber ring
so as to form the seat of the valve which consists of a vulcanite ball so far this is the
ordinary Ball Hydrant in present use. But it is to the working of the Ball or valve
that my invention applies.
Hitherto the Ball has been allowed to rise or fall in accordance with the pressure of
the water or the vacuity of the valve chamber, in which case any material reduction
in the amount and consequently the pressure of the water, through its being shut off
or throu any other cause-causes the Ball to drop and thereby leaves the entrance into
the valve chamber or main pipe open to receive any stagnent or noxious water or gas
which may have accumulated in the surface box, the important improvement invented
by me however prevents this and is of this nature, the vulcanite Ball (A) which forms
the valve is secured to its seat by a cup (B) and spiral spring (C) inserted in a
recess (D) in the valve chamber under the vulcanite Ball, the spring being made
longer than the valve chamber so that whatever the pressure of the water may be
even although there be no water in the valve chamber or main pipe the spring
keeps the Ball tight against the vulcanite rubber ring E-in the under surface of the
valve chamber cover (F) which forms the valve seat-thereby rendering the valve
chamber fluid tight the depression of the Ball so as to admit of entrance into the
valve chamber is obtained by pressure from without.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :
The invention of the Operation of a Spiral Spring to Ball Hydrants so as to keep
the valve or Ball in position independent of water pressure.
