PROVISIONAL SPECIFICATION.
Improvements in Water and Steam Heating Apparatus and in
Boilers therefor.
I, EDWIN PEAKE, of Fountain Square, Fenton, in the county of Stafford,
Plumber &c., do hereby declare the nature of this invention to be as follows:-
My invention relates to water or steam heating apparatus, and especially to that
class of such apparatus in which circulating pipes of small bore are. employed;
the chief objects of my invention being to provide an improved arrangement
of pipes whereby heat may be entirely cut off from one or more of a number
of rooms without affecting the others, to arrange the apparatus so that it can be
worked at either high or low pressure, and to provide an improved circulating
boiler.
According to my said invention a coil or equivalent arrangement of pipes is placed
in each room to be heated, the flow or inlet end of which is directly connected with
the circulating boiler; the other end of the said coil is connected with a return pipo
which is common to all the coils.
A cock is arranged in the flow end of each coil, by adjusting which cock the
circulation of water through the coil can be regulated without interfering with the
circulation through the other coils.
A closed supply tank is placed at a suitable level, which tank is of sufficient size to
avoid the necessity for constant refilling. The said tank is also provided with a water
gauge and with an expansion or overflow pipe.
The said overflow pipe is provided with a cock by closing which the pressure will
be caused to risc, so that the apparatus works under high pressure; when, however,
the cock is opened the apparatus works under low pressure.
The shell of the boiler is of elliptical shape in transverse vertical section or
formed with straight parallel sides and semicircular at the top and bottom.
Through the interior of the boiler extends a flue of the same shape internally as
the exterior of the shell, so that the water-space is of the same width all around
the flue.
The furnace is within the flue, so that the heat which radiates through the bars
assists in heating the lower part of the boiler.
The boiler is set in such a manner that the heat after leaving the internal flue,
through the opening at the rear end, passes along the outer sides of the boiler at the
lower parts thereof towards the front, and then returns along the upper portions
rearwardly to the chimney.
An important advantage of my invention is that air cannot get choked in the pipes,
as is the case with most systems of high pressure heating where a tubular boiler is
employed, so that any concussion in the pipes is avoided.

page_text: the same is to be performed to be particularly described and ascertained in and by
the following statement :-
My invention relates to water or steam heating apparatus, and especially to that
class of such apparatus in which circulating pipes of small bore are employed; the
chief objects of any invention being to provide an improved arrangement of pipes
whereby heat, may be entirely cut off from one or more of a number of rooms without
affecting the others, to arrange the apparatus so that it can be worked at either high
or low pressure, and to provide an improved circulating boiler.
In the accompanying drawing
Figure 1 is a diagrammatic elevation illustrating my improved heating apparatus
and boiler arranged to heat four separate apartments or rooms.
Figure 2 is a longitudinal section of the boiler drawn to an enlarged scale, and
Figure 3 is a cross section of the same.
According to my said invention a coil or equivalent arrangement of pipes is placed
in each room to be heated. These coils are shown at a, b, c, d in Figure 1. The flow
or inlet end e of each coil is directly connected with the circulating boiler f and the
other end y of the said coil is connected with a return pipe which is common to all
the coils.
A cock i is arranged in the flow end e of each coil, by adjusting which cock the
circulation of water through the coil can be regulated or shut off without interfering:
with the circulation through the other coils.
The circulation takes place in the direction indicated by the arrows.
A closed supply tank is placed at a suitable level which tank is of sufficient size to
avoid the necessity for constant refilling. The said tank also acts as the air vessel to
receive any air which may accumulate in the working and is also provided with a
water gauge k.
d' is the filling inlet of the tank j.
High pressure apparatuses have hitherto usually been worked with tubular boilers
which amongst other disadvantages are very difficult to clean.
Now according to my invention I make the shell of the boiler f, as clearly shown
in Figures 1 and 3, of elliptical shape in transverse vertical section or formed
with straight parallel sides and semi-circular at the top and bottom. Through
the interior of the boiler extends a flue m of the sanie shape internally as the
exterior of the shell so that the water space n is of the same width all around
the flue.
The furnace is within the flue so that the heat which radiates through the bars o
thereof assists in heating the lower part of the boiler.
The boiler is set in such a manner that the heat after leaving the internal flue m
through an opening m¹ at the rear end is caused by means of a fire brick partition q
to pass in the direction indicated by the arrows in Figure 2 along the outer sides of
the boiler at the lower parts thereof towards the front and then return along the
upper portions rearwardly to the chimney. The boiler is also fitted with a pressure
gauge (shewn in dotted lines in Figure 3) so that the heat can be regulated according
to the pressure at which the apparatus is required to work.
An important advantage of my invention is that air cannot get choked in the pipes
as is the case with most systems. of high pressure heating where a tubular boiler is
employed so that any concussion. in the pipes is avoided..
"Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim..is;:
(1) A heating apparatus comprising a coil or equivalent arrangement of pipes
placed in each room to be heated the flow or inlet end of each coil being directly
connected with the boiler and provided with a cock and the other end with a return
pipe which is common to all the coils and leads to the boiler, substantially as and for
the purpose herein before described.

of the accompanying drawing.
(3) The improvements in water and steam heating apparatus substantially as
herein before described with reference to the accompanying drawing.
