PROVISIONAL SPECIFICATION.
Improvements in Stoves.
I, MAYDAY LEE of 6, Greenfield Terrace, Llanelly, in the County of
Glamorgan, Master Mariner, do hereby declare the nature of this invention to be
as follows:-
A
This invention relates to an improved form of stove for heating purposes. It
is cylindrical and lined in the usual way with a fire-brick lining if necessary.
tube traverses the stove for nearly its entire length. Near the lower part of the
tube, and attached thereto is a circular disc perforated in any convenient way to
form a grate, upon which the fuel rests. The under-side of the disc at its outer
edge has teeth, so as to form a kind of level-wheel. A pinion working in contact
with these teeth and actuated 'from the outside, causes the disc with the central
tube to revolve. Also on the under-side of the disc, a regulating or damper plate
is attached thereto. This plate is bent to about two-thirds of the circumference of
the stove and of sufficient depth to completely cover the air supply port in the
outer shell, so that when the disc and damper plate are revolved, the air can be
admitted to any extent or cut off when required. The opening in the bottom of
the outer case provides for the ashes being withdrawn at will. The central tube
bas apertures made in any convenient position throughout its length; these adinit
air into the fire. Attached also to the outside of the tube are projections which
may be placed spirally. These projections, when the tube is revolved, help to
break up the coal and trim the fire, a suitable bearing being placed on the top of
the tube so as to keep it central. The aperture in the centre of the tube is open
and the gases are led away through an opening in the side near the top. The door
is made to open and revolve around a fixed pin, a handle with a screw arrangement
being provided for clamping the door when shut and preventing the escape of
smoke. A similar door is placed at the bottom of the stove and above the
revolving disc, for the purpose of cleaning out the grate and the like.
The central vertical tube may be made with longitudinal corrugations throughout
its length for use in burning anthracite and coal of that class, suitable orifices being
made in the pipe for the admission of air. The apertures in the revolving disc are
made larger or smaller according to the class of coal to be burnt. At the bottom
of the outside casing, an aperture is made through which a spindle is passed, and
to which a level pinion is attached for the purpose of revolving the disc with its
attachments. The disc before mentioned I prefer to make depressed at the centre
to a slight extent, somewhat after the fashion of an inverted umbrella, so that the
fuel will have a tendency to always fall towards the middle. The bottom opening
in the outer casing is made with sides to rest close up to the revolving damper, so
that the air is completely shut off when the damper is closed.
In some cases a projecting pin is made in the disc or an opening of the disc of
its outer edge, so that a rod may be inserted therein or a series of holes made in
the periphery, so that a pin or handle may be inserted therein.

I, MAYDAY LEE of No. 6 Greenfield Terrace, Llanelly, in the County of
Glamorgan, Master Mariner, 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 relates to improvements in heating stoves and fire grates, and in
order that it and the best way of carrying it into effect, may be thoroughly
understood, I will now describe it and them in detail, referring in so doing to the
accompanying figures which illustrate the application of my invention to an ordinary
upright stove.
Figure 1 is a sectional elevation of the stove.
Figure is a plan of the bottom grate.
Figure 3 is a plan of the ring upon which the bottom grate rests.
Figure 4 is a front elevation of the grated door.
Figures 5 to 8 are side elevations of different modifications of central tubes.
A is the stove casing; and B, the fire brick lining of the fire box C. D is a
circular bottom grate. In diameter, it is not more than the internal diameter of
the fire box, and rests upon an annular ring E which is itself supported by legs E',
the top ends of which are shouldered to engage in notches E, E in the edge
of the ring. E³, E' are perforations in the ring within the diameter of the fire
box, to supply air to the outer annulus of the grate bottom D.
F is a vertical pipe. Its foot is adapted to fit into the centre of the bottom
grate so as to turn with it. Figure 2 shows the presence of a triangular hole D¹.
The sides of the pipe F are perforated either with the holes For with the slots F
They may have projecting arms H fitted to them. Although the pipe is shown in
Figure 1 as extending to the full height of the fire box, my invention includes a
central perforated pipe of any height. A short pipe may not require to be
supported at its top, but a long one does. In the latter case, I provide such a
support as is illustrated in Figure 1, viz. -a transverse bar G having a central
socket G in which the top of the pipe F fits loosely enough to turn therein as the
bottom grate D is turned. This turning is effected by means of an external winch
handle on the axle I of an internal pinion J which engages in a crown gear J' fast
on the underside of the grate D and fitting within and just clear of the annulus E.
K is the fuel mouth; and K2, its door. L is the mouth for admitting air to the
fuel from above the grate D. L' is a grated door; and L2, an outer and dumb
plate for regulating that supply. Both are of the same size and external shape, and
both are pivotted upon a stud projecting from one side of the mouth L.
T is an opening adapted to supply air to the fuel from below the bottom grate D.
It may be fitted with any suitable damper.
U is the ashpit; V, the smoke flue; and W, its valve. X may be either an
ordinary removable cover or a combination of it and an evaporating pan.
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 :-
The combination in and with a heating stove or in or with a fire grate of any
type, of a revolving grate and perforated tube, as set forth.
