Specification of letters Patent Ho. 370, dated August 31, 1837.
To all whom it may concern :
Be it known that I, John S. Leavitt, of
Turner, in the county of Oxford and State
of Jtfaine, have invented a new useful Im-
5 provement in Cooking-Stoves; and I do
hereby declare the following is a full and
exact description, reference being made to
the accompanying drawings.
Plate I represents the stove with the fire
10 place as shown when put up ready for use.
A represents the front piece or plate over
the fire place. 1, 1 represents another plate
or piece about three inches wide immediately
above A. B represents a damper which closes
15 a valve above the fire place, when this valve
is closed the smoke passes under the plate
upon which the damper slides and through
an opening in the back of the fire place into
the chimney and up the flue thereof as in
20 common fire frames. C represents the door
of the oven. D the oven. E one side of the
fire place. F the clamper that closes the
valve over the oven. G the top of the stove
over the oven. H the boiler on the top of
25 the stove over the oven. I the funnel of
the stove. J the plate at the right hand of
the oven. K represents the plate upon
which is placed two small boilers L and M.
N the small plate in the rise between the
30 large and small boilers. O represents the
large boiler. P the plate upon which it
stands. Q the end of the stove at the right
hand. E, the corner of the stove between the
end of the stove at the right hand and the
35 door of the furnace. S represents the fur-
nace. The piece marked 2 represents the
plate above and on the right side of the door.
T represents the door of the furnace. U,
the hearth around the furnace. V the side
40 of the fire place. W and X the legs of the
stove. Y the back of the fire place. Z the
hearth upon which the stove stands. The
clots on the plates marked B. Q- represent
two air holes.
45 Plate II is a view of the stove with a part
of the top and some of the front plates taken
away in order to show more fully the inte-
rior structure of it.
The same letters refer to corresponding
50 parts in Plate I. The crooked arrows show
the course of the flame and smoke from the
Plate III is a section of the stove also
showing the course or direction of the flame
55 and smoke from the furnace and fire place.
The letters refer to the corresponding parts
on Plate I.
Operation: When used for cooking or
the common purposes to which such stoves
are put, a fire is put into the furnace S and 60
the flame regulated by means of the dampers
described above. As many people are de-
sirous of seeing the fire, or prefer an open
fire place to sit by, a fire may be put into
the fire place Y whenever necessary or in 65
evenings. Much of the heat from the fire
place may be sent up around the oven and
under the boilers L and M by drawing back
the clamper B.
Different sizes of lids or covers may be put 70
upon the openings over the top for dif-
ferent sized boilers as in the usual way.
It will be seen that the nature of my im-
provement consists in the arrangement of
the boilers — in the mode of conveying heat 75
from the furnace to the boilers — in the ar-
rangement of the oven and the manner in
which it is heated— in the open fire place
and the manner of conveying heat from it
through the orifice in the top and also in SO
the combination of the several parts of the
stove — in reference to the space which, it is
The small boilers are heated directly by
the fire communicated from the furnace be- b-5
neath without the intervention of any ob-
stacle whatever. This is not the case in any
other cooking stoves within my knowledge.
The oven which is situated higher than any ■
other part of the stove, has a vacant space 9o
on the right hand and on the left hand and
also over its top as well as under its bottom ; .
through which space the heat is conveyed
directly from the furnace or from the top of
the fire place by which means it may be ti'6
The clamper B covers the opening through
which the heat from the fire place passes.
What. I claim as my improvement is —
The combination and adaptation of an 100
open fire place with a cooking stove having
a furnace, oven boilers holes &c, substan-
tially as above described.
In testimony that the above is .a true
specification of my said improvement I have 105
hereunto set my hand this twenty first dav
of April 1837.
