Improvements in and relating to Fittings for Heating Apparatus
and the like.
I, ROBERT GRUNDY BROOKE, of Upton Grange, Macclesfield, in the County.
of Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to fittings for use in conjunction with continuous circu-
lation heating apparatus and is applicable to that type of apparatus which is
employed for the warming of buildings, conservatories and the like, in which
the heating is effected by radiators through which the heating fluid is passed.
In continuous circulation heating apparatus in which a circulation of hot
water actuated by a steam injector or other steam jet apparatus is employed
with radiators branching out of, and returning to, a main circulation pipe a
cock or cocks is usually provided at each radiator by the closing of which the
radiator may at any time be cut out from the circulation. If however, through
inadvertence the wrong cock only is shut or is shut in the wrong order then the
flow of water through the pipes at that point is also stopped thereby completely
stopping the entire circulation throughout the whole system.
The object of my invention is to provide a neat and compact fitting by means
of which one or a number of radiators may be cut out of a circuit without the
possibility of causing interference with the circulation of the heating fluid.
My invention consists in providing a suitable union or valve casing which I
connect in the main circulation pipe and with the radiator, and in combining
with this union or valve casing a valve or valves which may be adjusted to
divert the flow of heating fluid through the radiator or to cut off the radiator
and allow the flow to take place direct through the main pipe.
In carrying my invention into effect according to one modification, as adapted
for connection to individual radiators in a branch heating circuit from the main
supply, I form a casting of three branch pipes uniting together at a common
junction. Two of the branches, the main inlet and outlet branch, are in a
direct line with each other and are suitably screwed at their ends for coupling
in the main line of piping of the heating circuit. The end of the third, or
radiator branch is, also suitably screwed for connection to the inlet pipe of the
radiator by means of a union nut.
The junction of the three branch pipes is bored out to receive a hollow cylin-
drical or tapered plug cock, which is fitted with a suitably packed gland. Two
apertures or ports are cut in the body of the plug in such positions that when
the plug is turned so as to close the outlet passage the fluid is diverted from the
inlet branch through the radiator. When the plug is turned so as to shut off
the radiator branch, the flow takes directly through the other two branches.
With the cock in any intermediate position part of the flow takes place through
the radiator and part directly through the main pipe. This arrangement pre-
vents the possibility of the current being stopped while changing the valve

page_text: from one position to another. The cock is provided with a suitable handle
which carries a pointer and the union casing is clearly marked to indicate the
positions of the handle for adjustment of the cock.
According to another modification of my invention, I form a three way valve
casing which is fitted with two partitioning webs one above the other. The
webs are bored out to form seats for two valves, of the mushroom or other suit-
able type, fixed upon a vertical spindle. The lower valve is inverted and con-
trols the passage from the inlet branch to the radiator, and the upper one controls
the passage between the main and outlet branches. The spindle carrying the
valves is loosely connected to a screwed spindle which passes through a stuffing
box in the top of the casing and is fitted with a hand wheel. Suitable index
marks are provided upon the wheel and casing to permit of proper adjustment
of the valves.
According to a further modification of my invention I form a casting of four
branch pipes uniting together at a common junction, two of the branches of
which I connect to the inlet and outlet of the radiator respectively, the other
two being connected in the supply pipe. At the junction of the branches I
provide a suitable cock or valve which may be adjusted so as to shut off the
radiator branches completely or to divert the flow of heating fluid through the
radiator.

Improvements in and relating to Fittings for Heating Apparatus
and the like.
I, ROBERT GRUNDY BROOKE, of Upton Grange, Macclesfield, Cheshire,
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:-
My invention relates to fittings for use in conjunction with continuous circu-
lation heating apparatus and is applicable to that type of apparatus which is
employed for the warming of buildings, conservatories and the like, in which
the heating is effected by radiators through which the heating fluid is passed.
In continuous circulation heating apparatus in which a circulation of hot
water actuated by a steam injector or other steam jet apparatus is employed
with radiators branching out of, and returning to, a main circulation pipe a
cock or cocks is or are usually provided at each radiator by the closing of which the
radiator may at any time be cut off from the circulation. If however, through
inadvertance the wrong cock only is shut or is shut in the wrong order then the
flow of water through the pipes at that point is also stopped thereby completely
stopping the circulation throughout the entire system.
The object of my invention is to provide a neat and compact fitting by means
of which one or a number of radiators may be cut out of a circuit without the
possibility of causing interference with the circulation of the heating fluid.
My invention consists in providing a suitable union or valve casing which I
connect in the main circulation pipe and with the radiator, and in combining
with this union or valve casing a valve or valves which may be adjusted to

page_text: divert the flow of heating fluid through the radiator or to cut off the radiator
and allow the flow to take place direct through the main pipe.
In the three accompanying sheets of explanatory drawings:-
Figure 1 is a sectional elevation, and
Figure 2 a sectional plan of my improved valve fitting.
Figure 3, 4, 5, and 6 are similar views of modified forms of my improved
valve fitting.
In carrying my invention into effect according to one modification, as adapted
for connection to individual radiators in a branch heating circuit from the main
supply, I form a casing A of three branch pipes uniting together at a common
junction. Two of the branches, the main inlet a and outlet branch b, are in a
direct line with each other and are suitably screwed at their ends for coupling
in the main line of piping of the heating circuit. The end of the third or radiator
branch c is also suitably screwed for connection to the inlet pipe of the radiator
by means of a union nut.
The junction of the three branch pipes is bored out to receive a hollow cylin-
drical or tapered plug cock B, which is fitted with a suitably packed gland D.
The apertures or ports e, f, are cut in the body of the plug in such positions
that when the plug is turned so as to close the outlet passage b, the fluid is
diverted from the inlet branch through the radiator. When the plug is turned
so as to shut off the radiator branch c, the flow takes place directly through the
other two branches a, b, with the cock in any intermediate position, as for
example as shown in Figure 2, part of the flow takes place through the radiator
and part directly through the main pipe. This arrangement prevents the possi-
bility of the current being stopped while changing the valve from one position
to another. The cock is provided with a suitable handle which carries a pointer
and the union casing is clearly marked to indicate the positions of the handle
for adjustment of the cock.
According to another modification of my invention as shown in Figures 3
and 4, I form a three way valve casing which is fitted with two partitioning
webs F, F, one above the other. The webs are bored out to form seats for two
valves G, H, of the mushroom or other suitable type, fixed upon a vertical spindie.
The lower valve H is inverted and controls the passage from the inlet branch a¹,
to the radiator c¹ and the upper valve G controls the passage between the main
inlet and outlet branches a¹, 61. The spindle carrying the valves, or the head
of the valve G, is loosely connected to a screwed spindle K which passes through
a stuffing box in the top of the casing and is fitted with a hand wheel or lever.
Suitable index marks are provided upon the wheel or lever and the casing to
permit of the proper adjustment of the valves.
According to a further modification of my invention I form a casting of four
branch pipes uniting together at a common junction, as shown in Figures 5
and 6, two of the branches 2, 3, of which I connect to the inlet and outlet of
the radiator respectively, the other two, a2, 2 being connected in the supply pipe.
At the junction of the branches I provide a suitable cock or valve L which may
be adjusted so as to shut off the radiator branches completely or to divert the
flow of heating fluid through the radiator.
I modify the form of my casing and the type of valve for working within it
to suit the particular fitting branches or pipes to which it is to be attached.
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:-
1. The improved union valve or fitting for use in connection with the circu-
lation pipes and radiators or the like of a heating system, for enabling the flow
of the heating fluid to be diverted and controlled substantially as hereinbefore
described and as illustrated in the accompanying drawings.

page_text: 2. In a system of heating pipes or mains, the arrangement of a valve
or fitting operated by a manipulating lever or hand wheel, by means of which
one or a number of radiators or the like may be cut out of circuit without inter-
fering with the circulation of the heating fluid, substantially as herein before
described and as illustrated in the accompanying drawings.
