COMPLETE SPECIFICATION filed by the said William Henry Tayler
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 18th October 1871, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY TAYLER, of Tudor House, Anerley, in the County of Surrey,
Doctor of Medicine, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
STOVES FOR BURNING GAS OR GAS AND AIR FOR GENERAL HEATING AND COOKING
PURPOSES,” and have petitioned Her Majesty to grant unto me, my

page_text: executors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that I am the first and true
Inventor thereof.
.!
NOW KNOW YE, that I, the said William Henry Tayler, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement:-
My Invention has for its object improvements in stoves for general
heating and cooking purposes for burning gas or gas and air,
whereby the unpleasant odours and deleterious matters given off from
gas stoves generally are either purified, destroyed, or entirely removed.
For this purpose I make the stove, by preference if for heating pur-
poses, of a conical or cylindrical form either in metal, or fire-clay, or of
both combined, or of any other material or materials not injuriously
affected by heat. It consists of a combination of two or more chambers
placed vertically one over the other, leaving an annular space com-
municating with the external atmosphere between each chamber.
Openings are also provided allowing the heated air to pass from one
chamber into another, so as to produce a free ventilation and constant
supply of fresh air within the body of the stove.
In addition to the above method of constructing the stove, I attach
on the inside and outside of the first chamber, and on the outside of the
second chamber in the event of three chambers only being used, a
trough, which said trough I partly fill with any known substance or
substances which will decompose, absorb, or destroy any impurities
given off from the gas or gas and air during the process of combustion.
I also attach on the inside or outside of the stove, according to its size
and shape, a boiler for containing water, the steam from which is
allowed to pass within the body of the stove so as to supply moisture to
the atmosphere circulating through it, and thus prevent the heated air
passing out in too dry a state.
The stove is fitted to receive if necessary a pipe, which may be
connected with any flue, or may be extended to supply heated air to a

page_text: These several arrangements apply to stoves for heating purposes
generally, and I use them separately or combined according to the
purpose for which the stove is required, such for example as in the
difference between heating an outbuilding or a conservatory.
•
In stoves for cooking purposes I employ chambers arranged in the
manner before described for the free ventilation of air through the body
of the stove, giving the preference to two chambers of an oblong form.
On the top and outside of the upper chamber I construct an oven and
boiler; one or more of each according to the size of the stove, leaving an
open space in the middle communicating with the body of the stove,
which space is fitted to receive any cooking utensil for boiling, frying, or
grilling. I do not confine myself to any particular form of burner for
heating the stove, but I prefer one of wire gauze or finely perforated
metal having a disc of metal, or fire-clay, or any material not injuriously
affected by heat fixed over and at a short distance from the gauze or
perforated metal, which disc causes more complete combustion of pro-
ducts given off from the gas, and also more generally diffuses the heat.
-
From the different arrangements employed in the construction of the
stove it will be seen that,-
1st. Owing to the free ingress of fresh air to the body of the stove,
and to the ventilation between one chamber and another, the air inside
the stove is prevented from becoming overheated and giving out the
unpleasant odour to which this is mostly due, while this arrangement
also favours the more complete combustion of the gas.
2ndly. That as all products of combustion and the heated air, are
compelled to pass before mixing with the external atmosphere over
and through the purifying substances contained in the before-described
troughs, they are thus freed from all obnoxious matters.
3rdly. That the application of steam to the internal parts of the stove
prevents the contained air from becoming too dry and its natural
moisture from decomposition, thus allowing a proper moist heated air
to pass out, and so removing another source of odour.
The chambers can be constructed of any size and shape, and the
arrangements will be better understood by reference to the accompanying
Drawings.

Fig. 1, Sheet 1, is an elevation of plain three-chambered circular
stove, arranged to give free ventilation to the several parts. Fig. 2

chamber closed with a cover, on which is placed a small vessel G
containing 'water for evaporation; M, the gas or gas and air burner;
N, bed plate on which the stove and burner M stand; O, the feet of the 1
stove.

the troughs for holding the substance or substances for purifying the
products of combustion. Fig. 5 is a transverse section of the same,
showing the arrangement of the troughs filled ready for use, as also the
boiler for supplying: steam. to the stove. Fig. 6 is a plan of the above,

municating with the second chamber, and a large opening running
through both chambers and through the boiler H to an open space at
the top; B, annular space between the first and second chamber; O, the

Having thus described the nature of my said Invention, and the mode
in which I carry the same into effect, I would have it understood that I
do not confine myself to the precise details herein shown and described,
but what I do claim is, the several improvements in the construction of
a stove whereby a free ventilation is maintained within the internal parts
of the stove, the odours removed, and the impurities given off during the
combustion of the gas absorbed and destroyed.
In witness whereof, I, the said William Henry Tayler, have
hereunto set my hand and seal, this Eighteenth day of October,
in the year of our Lord One thousand eight hundred and seventy-
one.
