PROVISIONAL SPECIFICATION.
Improvements in Boilers for Stoves.
ROBERT ENOCH ROBERTS No. 2 Burges Road East Ham Essex Plumber do
hereby declare the nature of this invention to be as follows:-
It consists of a boiler of convenient shape dimensions and material which
boiler consists of a square formed by tubes so that the fire can play all over
the heating surface of the boiler and pipes the square shaped portion of the
tubes I make to fit any ordinary fire place or stove when this apparatus is in
action the fire surrounds the part formed for the boiler and heats the water
instantly and creates a rapid supply of hot water, being strong and simple in
construction it will not be likely to get out of order.
It consists of a boiler which is made of the best steel steam piping, sizes
sides square
1 in. x 1 piping the apparatus is made to fit kitcheners & stoves,
so to get firing all around pipes with this apparatus bars of stoves can be done
away with if needed. It works with easy bends and a rapid rise, it fits in all
around fire place fire in the centre so false bottom can fit in to save firing. It
can be with or without false bottom, with false bottom from lighting fire will
heat 25 gallons of water in 30 minutes without false bottom will do same work
in 20 minutes, pipes fitted to this apparatus from flow pipe against boiler tee peice
to fit to draw off tap, to draw hot water and to empty tank and clear pipe,
tee piece to fixed against boiler off of straight pipe so bends should be fitted to
hot water tank on flow pipe so to cause no checks Return pipe should be fitted
entering wall to boiler with a tee piece instead of a bend, so short peice can
drop down from tee to catch scales fronr tank and pipe before entering boiler.
The flue is arranged so all ranges can be used as an open fire place when this
is fixed, needs no attention tubes will not furr up or make any rattling noise or get
out of order.

I, ROBERT ENOCH ROBERTS of Hazlewood Villa, Burgess Road, East Ham
London, E. Plumber, 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 refers to arrangements for heating water for baths and other
purposes, and is designed to provide an efficient and inexpensive substitute for the
costly high pressure boiler now in general household use.
It consists in continuing the usual pipes or in connecting them to another pipe
made preferably of steel, or of iron of high quality, or of copper, which is coiled
or wound spiral fashion inside the ordinary fire-box of the stove or range.
One or more of these coils may be used and they may be formed of any size
tube.
By preference the coils follow as far as possible the shape of the fire-box, but
have rounded corners so as to offer little or no resistance to the circulation of the
heated water.
They may form in front the bar of the fire, or may lie contiguous thereto.
Ranges fitted with this tubular form of boiler, can be more easily converted into
open fire grates as they have no back boiler, and the flue can be carried under a
larger area of the hot plate, thus heating it more effectually.
In order to create a galvanic current to soften the water, a piece of zinc and
some copper wire can be fixed inside the tee piece, where the branch pipe is taken
off, to supply a tap.
A short vertical pipe stopped with a plug or tap, forming a drop piece, is fixed
on a tee piece, of the inflow pipe, to receive sediment, rust or scale formed in
the coil.
There will be no danger of my tubular boiler exploding, as it does not hold
steam.
I will now describe the invention with reference to the accompanying drawings
in which:
Fig. 1. shows a perspective view of a range fitted with my improved hot water
circulating coil, which in front forms the bars of the grate.
Fig. 2. shows a plan view of the circulating coil contained in the fire box. The
coil in this instance is behind and parallel with the bar or bars.
Fig. 3. shows a perspective view of two coils of the circulating pipes detached.
Fig. 4. shows a plan view of a slightly modified form of an arrangement of pipes
for a single coil, and is furnished with a tee-joint and draw-off pipe for supplying a
tap in front of range.
In all the figures the arrows indicate the direction taken by the water.
a is the fire box of the range.
a', is the cast bar of the same.
b, is a tap for drawing off cold water.
61, is a tap for drawing off hot water.
c, is the cold water supply pipe.
d, is the hot water return pipe.
The back of the coil is preferably sloped to suit the configuration of the grate as
shewn in the plan view Fig. 4.
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 I am
aware of the Specification of Letters Patent dated 27th July 1892 No. 13700

page_text: granted to W. H. Bushell and it is to be understood that I do not claim anything
described and claimed therein, but what 1 claim is :
In a range or stove and for like purposes, a heating coil for water, of steel or
iron pipe wound spirally around the interior area of fire box, and following nearly
the dimensions and outline thereof, said coil forming in front the fire bars, or
lying behind and contiguous to said bars, as herein described and set forth.
