page_text: We, ROBERT GEORGE RESTALL, GEORGE FREDERICK RESTALL and EDWARD
WILLIAM RESTALL, all of Commercial Road, Bournemouth, in the County of Hants,
and of Marylebone Road, in the County of Middlesex, Sanitary Engineers, do hereby
declare the nature of our said 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 relates to certain improvements in the construction of stoves, the
principal object of the Invention being to impede the escape of the products of com-
bustion from the stove by causing the same to take a repeatedly interrupted, circuitous
or circumferential course in such a manner as that the heat is utilized to its best
advantage, and is prevented from escaping directly to the flue or chimney as in
existing analogous apparatus.
The Invention is illustrated on the accompanying drawings in various modifications
of its application. Fig. 1. represents an elevation, parily in section, of a stove
constructed in accordance with the present improvements. Fig. 2. is a sectional plan
view thereof. Figs. 3 to 5, are sectional elevations of other modifications, and Fig. 6,
is a plan view of Fig. 5.
The store may be constructed of galvanized sheet iron or of any other suitable
metal or material, and may be made of any suitable shape and ornamental configura-
tion, and the beat may be provided by the combustion of gas or of mineral oil or
other suitable heating agent.
In the modification represented in Figs. 1 and 2, the object of the invention is
obtained by the formation of the stove with a series of contiguous and communi-
cating chambers, 7, formed by the external front, back and side plates 8, 9, 10, and
by internal division plates, 11, throughout the longitudinal extent of which chambers,
or nearly so, the products of combustion are caused to pass, the adjacent chambers
only communicating at one place arranged at the lowest practicable position, through
holes or openings, 12, made in the plates, 11. The products of combustion firstly
rise into a central hot chamber, 13, which is constantly maintained at an elevated
temperature and escape therefrom in the manner above indicated through the series of
chambers, 7, from the external one of which they finally escape at the opening, 14,
whence they are led by a flue pipe, 15, to any convenient chimney or outlet or the

page_text: outermost chamber, 7, may be divided by a plate 11* so as to lead the escaping
products to a higher outlet 14*. Provision for a current of heated air through the
chamber, 13, is afforded by a top hole, 30.
As aforesaid, any suitable heating agent may be used, and the burners and fittings
thereof would require to be adapted thereto.
16. represents a ring-burner for gas, which is fitted on a supply-pipe 17, with
facility of turning theroon, and is connected by a stay, 18, to a door, 19, hinged at, 20,
to a door-frame, 21, adapted to the stove-case in such a manner as that when the door
is sufficiently opened the burner is brought outside of the stove-case so that the
ignition of the gas can be safely effected. Air to support the combustion enters into
the bottom part of the chamber, 13. 31. represents a shield plate adapted between
the burner and the opening, 12, into the first chamber, 7.
In the modification illustrated in Fig. 3. substantially the same result is obtained by
causing the products of combustion to traverse a course alternately towards the centre
and the circumference of the stove, by arranging the division plates, 11, and forming
holes or openings, 12, therein, in the manner represented. The plates, 11, with the
central holes, 12, may extend across the whole width of the stove, and the inter-
vening plates, 11, may be supported by stay bars, 24, rising from the aforesaid
plates 11. so as to leave annular openings, 12, between them and the stove case, and
their edges are deflected so as to cause the products of combustion to be kept to the
greatest convenient extent adjacent to the circumference of the stove-case, such products
finally escaping through the opening, 14, whence they may be led away as afore-
said.
In the modification illustrated in Figs. 4, to 6, the stove is shown as surrounded by
an additional or hot-air chamber, 25, through which a continuous current of the
outer air is caused to pass by the action of the stove, such air entering the
chamber by holes or openings, 26, made in the lower part thereof and escaping
into the room or place to be warmed by holes or openings, 27, made in the upper
part of the casing, 25. Within the stove chamber the aforesaid main object of the
invention is obtained by arranging the plates, 11, in the manner illustrated, and .by
forming the holes or openings, 12, in the alternate plates at opposite sides of the
stove, and by applying between the plates, 11, other partitions, 28, dividing such
chambers, 7-holes or openings, 29, being made in opposite sides of such partitions, 28,
so as to cause the products of combustion to be kept continuously near to the circum-
ference of the stove case, and the edges of the openings, 12, in the plates, 11,
adjacent to the sides of the stove case being deflected or so shaped as to aid in
effecting this action.
In the modification illustrated in Fig. 4. the stove chamber is made of a double
conical formation and is adapted, with suitably supported baffle plates, 11, which cause
the producis of combustion to keep adjacent to the circumference of the stove until
they escape at the outlet, 14.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The hereinbefore described improvements in the construction of stoves.
2. The peculiar formation of stoves as hereinbefore described with reference to
the accomnaning drawings
