Feed Water Governor.
WILLIAM ROBERT PETHER Civil & Mechanical Engineer 178 Bridge Road,
Battersea Surrey and ROSSALL WILLIAM PAPINEAU Leadenhall House London E.C.
Civil Engineer do hereby declare the nature of this invention to be as follows:-
An apparatus for maintaining water or other liquid in steam Boilers or other
vessels at any adjustable level:
The apparatus consists of a float of any suitable material and of convenient
dimensions which rising and falling with the level of the surface of the liquid is
connected by a rod or other attachment passing through a stuffing-box to a lever
fixed outside the vessel or the float may be connected directly inside the vessel to the
lever acting inside. Thus the level of the float acting by means of the lever regulates
the supply either by putting in action a pump injector or other machinery or by
opening and closing the supply or overflow.

Feed Water Governor.
WILLIAM ROBERT PETHER 178 Bridge Road Battersea Surrey Engineer ROSSALL
WILLIAM PAPINEAU Leadenhall House London E.C. Civil 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:-
An apparatus for maintaining water or other liquids in Steam Boilers or other
vessels at any adjustable level. The appliance consists of a float of any suitable
material and of convenient dimensions which floating at the level of the surface of the
liquid is connected by a rod, wire or other suitable means passing through a stuffing
box to a lever fixed outside or the float may be connected directly inside the vessel to
the lever acting inside. Thus the float acting by means of the lever regulates the
supply either by putting in action a pump injector or other machinery or by opening
and closing the supply or overflow.
We will now describe with reference to the accompanying drawings the manner in
which our said invention is to be performed.
Fig. 1. represents in part section and elevation a feed water governor as it can be
constructed and fitted to a Cornish boiler.
A is the back pressure or check valve through which the supply of water passes
into the boiler.
C is the
A portion of the shell of the boiler is shewn and marked B.
supply pipe through which the feed water is circulated by a pump or other machine
D is an equilibrium or other stop valve E is the return pipe to conduct the feed
water back to the pump or other machine F is a float made of any suitable material
and dimensions G is a guide through which the connecting rod (H) of the float is
allowed to work. I is a lever fixed on the spindle J with the other end attached to
the connecting rod H. K is a double lever being fixed near the centre on the
spindle J one of the ends being connected with the weight L and the other end with
the connecting rod M. N is an ordinary stuffing box fitted to the shell of the boiler.
O is a socket with a left-handed thread on the one side and a right-handed thread
on the other.

page_text: The operation of the parts above described is as follows.
The float F floating at the level of the desired water level (which can be regulated
by lengthening or shortening the connecting rods M by means of the socket O) is
connected with the equilibrium valve D by means of the connecting rods H. M. and
the spindle J therefore if more water is required in the boiler the float F falls and
closes the valve D cutting off the circulation of the water through the pipe E, the
water then passes through the check valve A into the boiler and raises the float F to
the mean water level and thereby opens the valve D sufficiently to retain the water
at the desired level in the boiler or if the water should rise too high in the boiler it
acts upon and opens the valve D through which the water is allowed to pass until
such time the water has evaporated in the boiler to bring the float F again to the
mean water level.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1st. In an automatic feed water governor for steam or other boilers, the com-
bination with the circulating, overflow, supply or suction valve or valves and float
and float connecting rods of means for working the said valves from the said float,
substantially as, and for the purposes, described.
2nd. The arrangement and combination of parts constituting the automatic feed
water governor for steam or other boilers herein before described and illustrated by
the accompanying drawing.
