1, HERBERT JOHN HADDAN, of 67 Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The present apparatus serves the purpose of providing stoves or other heating
apparatus periodically with a cortain quantity of fuel corresponding to the consumption
so that for longer spaces of time, for instance for a day, these heating apparatus do not
require any further attendance.
The apparatus consists of a cylinder of motal, preferably of sheet iron, and
hermetically closed above by a cover. In the cylinder are further arranged the two
cross partitions, placed at a short distance apart in the upper portion of the cylinder,
the upper being connected by screws with the cylinder so that it can be at any time
removed from the latter while the lower partition is securely fixed to the cylinder so
that at the places of connection neither air nor dust can penetrate.
The interior of the cylinder is divided from its lower end up to the lower cross
partition, by radially arranged separating walls, the number of which varies according
to the size of the apparatus. Each of the divisions thus formed is closed below by a
flap hinged to the cylinder so as to fall outwardly and corresponding in shape to the
cross section of the divisions.
The central pipe serves as a casing for a shaft which is guided centrally in the
cylinder in journals arranged at opposite ends of the pipe. The upper extremity of
this axle is connected with a spring driving work supported on the upper cross
partition. The shaft carries at its lower end a small removable disc having a lateral
recess, and with two oppositely arranged perforations into which a suitably constructed
key may be introduced by means of which the shaft is turned so as to wind up the
driving work.

page_text: The inner ends of the flap carry projecting pins which, when the compartments are
closed below by the flaps, rest upon disc and thus secure the flaps in position.
The partitions being filled with coal or other fuel and the flaps closed and secured
by the disc the shaft and disc are set in slow rotation by the driving work whereby
the pins of the flaps arrive in gradual succession over the recess in the disc, the flaps
thereby loose their support and fall down by the pressure of the coals in the partition
so that each partition is successively emptied into a funnel arranged below-from
which the coals fall into the place of combustion by pressing down by their weight
counterbalanced flaps which close the lower mouth of the funnel. After the coals
have passed the flaps, the latter are automatically brought to their former position by
the counterpoises.

page_text: The apparatus may be so arranged that, for instance, about every two hours a
corresponding quantity of coals sufficient to produce a certain heat in the respective
place, is introduced into the fire without any further assistance. When all the partitions
of the apparatus are emptied, this may be indicated by a signal apparatus connected
with the clock work K.
To fill the apparatus with fuel, it is removed from the mouth of the hopper M placed
upside down so as to wind up the clock work K.
The inner ends of the flaps G carry projecting pins n, which, when the compart-
ments are closed below by the flaps, rest upon disc L' and thus secure the flaps
in position.
The partitions being filled with coal or other fuel and the flaps closed and secured
by the disc, the shaft H and the disc L are set in slow rotation by the clock work,
whereby the pins n of the flaps arrive in gradual succession over the recess in the
disc L, the flaps thereby lose their support and fall down by the pressure of the coals
in the compartment so that each compartment is successively emptied into a hopper M
arranged below, from which the coals fall into the place of combustion by pressing
down by their weight the counterbalanced flaps 0 0 which close the lower mouth of
the hopper, and the fuel is introduced into the separate compartments. The flaps may
then be secured one by one, as the disc L is turned by introducing each pin n through
the slote as the latter arrives below the same when the disc Lis turned. The apparatus
is then replaced over the hopper M and the stove is again provided for a further space
of time with the necessary fuel. To prevent the clock work from being injured by the
shock caused by the falling in of the coals, the double bottom C D is arranged; the
clock work being contained in a hermetically closed space is thereby protected from
dust. In order to perform any necessary repairs to the clock work it can be easily
and expeditiously removed from out the apparatus since the cover band cross
partition Care both adapted to be unfastened.
Instead of six compartments as shown in the drawings, more or less may be
arranged corresponding to requirement, without departing from the scope of the
invention. It is obvious, that the apparatus may be manufactured in all sizes and for
various heating purposes.
As the apparatus can be filled with coals outside a room, it admits firstly of great
cleanliness, as no dust can be created by the coals and further it is very important in
a sanitary point of view, since no gases, dust or smell can pass from the coals into the
atmosphere of the room. Even if the apparatus is removed from its place for the
purpose of fresh filling, no hurtful gases can penetrate into the respective room, since
by the flaps OO the hopper M is perfectly closed.
The temperature of the room being continuously uniform, explosions and injuries to
the stove by overheating are perfectly excluded.
The apparatus works economically and can be attached to stoves chimneys etc. of
any construction without great expense.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is:
For use with stoves and other heating apparatus, a fuel feeding contrivance, by
means of which at certain intervals of time a predetermined quantity of fuel is
introduced automatically into the place of combustion.
