Pullout firebox drawer
Abstract
A wood-burning stove includes side-walls joined together in an
airtight manner to form a firebox and a heat chamber there above.
The firebox in this wood-burning stove is a drawer on
rollers/sliders and pulls out for ease of placing fuel exactly
where the operator wants it and severely decreases the risk of
injury or burning. This is accomplished by not having to place the
fuel into the enclosed cavity of the wood-burning stove increasing
risk of injury and decreasing the accuracy of where you would like
to place the fuel in the firebox. In addition there are knobs that
control the airflow into the firebox that controls the combustion
giving the operator control over the temperature in the firebox and
allows the fuel to burn more efficiently.

BACKGROUND OF THE INVENTION
[0002] The present invention relates to a stove apparatus for the
combustion of solid fuel, such as wood logs, to provide heat for a
dwelling, cooking of food, or the like and, more particularly, to
such a stove apparatus having walls joined together in a
substantially airtight manner to form a firebox and heat chamber
there above with an air-supply manifold provided with a plurality
of spaced-apart, air-discharge openings to direct streams of heated
air toward the fuel while supported in the firebox for the
combustion process. The present invention further provides an
improved access door to permit easier loading of fuel into the
firebox. This is accomplished by putting the entire firebox on
rails or rollers so the entire firebox can be pulled out as a
drawer. This makes loading fuel into the said firebox much safer
from burns and easier to place the fuel in the exact spot
desired.
[0003] Known designs for fireboxes failed to provide adequate
control of the air supply to control the combustion process. Slide
or rotary plate members were usually positioned at a convenient
location sometimes dictated only to satisfy the aesthetic
appearance for controlling a supply of air. One or more logs used
for fuel are usually supported on a grating or directly on a
fire-resistant floor space at a site which is distally spaced
sometimes by as much as 10-12 inches from the opening provided to
deliver the necessary air for combustion. Since the space within
the firebox walls is usually subject to a chimney draft, control of
the air supply for the combustion process was erratic and fuel was
consumed at a wastefully-excessive rate.
[0004] The present invention is based, in part, on the discovery
that not only is it necessary to control the quantities of air
which are supplied into a wood stove but also that the air supplies
must be conducted to a point closely adjacent the supply of wood
fuel for an effective control of the combustion process. A wood
stove of this type must, therefore, be not only of robust
construction for longevity but also the walls must be joined
together in a substantially airtight manner. To achieve an airtight
pullout firebox drawer we have provided two heavy-duty clamps to
effectively make the firebox airtight when closed. These clamps are
very similar to the ones used on conventional wood burning stoves,
only instead of only having one clamp and hinges on the opposing
side there are two clamps one on either side of the drawer.
SUMMARY OF THE INVENTION
[0005] It is an object of the present invention to provide a stove
apparatus for the combustion of solid fuel, such as wood logs,
while supported in a firebox formed by surrounding stove walls
wherein the stove apparatus includes an air-supply manifold having
a plurality of spaced-apart, air-discharge openings directed toward
the fuel; the manifold extending through an opening in one of the
stove walls to conduct the flow of air in or in close proximity to
the firebox so that conductive heating of the air in the manifold
occurs for the discharge of heated streams of air through the
openings toward the fuel.
[0006] It is a further object of the present invention to provide a
stove apparatus for the combustion of solid fuel such as wood logs
wherein stove walls include a pullout firebox drawer. Said pullout
firebox drawer decreases the risk of injury of being burned while
attempting to place fuel in the firebox. The operator of a pullout
firebox drawer does not need to place any part of their body into
the oven cavity drastically decreasing the risk of injury. Also
this makes placing fuel in an exact spot in the firebox that much
easier because you have an open area to place the fuel in any
location in the firebox not just the spots you can reach inside a
conventional wood-burning stove.

DETAILED DESCRIPTION OF THE DRAWINGS
[0017] In the description that follows, like parts are marked
throughout the specification and drawings with the same reference
numerals, respectively. The drawing figures might not be to scale,
and certain components can be shown in generalized or schematic
form and identified by commercial designations in the interest of
clarity and conciseness.
[0018] Referring to the drawings the main fuel tray assembly
without the main firebox is identified by numeral 100. The main
fuel tray 102 is where the fuel will be burned and is where the
fuel grate 104 sits. The ash tray handle 106 gives the operator of
the firebox a sturdy handle to grasp and pull the firebox out. 106
the ash tray handle is connected to the ash tray pan 108. The ash
tray pan collects the burnt ashes from 102 the main fuel tray and
is where the main fuel tray sits. The mounting feet 112 sit flush
with 108 the ash tray pan and sit on top of and welded to 110 the
wire rack. The mounting pin 114 slides through 112 the mounting
feet and secures 112 the mounting feet to 108 the ash tray pan and
to 102 the main fuel tray. Numeral 116 show the large oval shaped
vent holes in 102 the main fuel tray and allow for better air flow
into the bottom of fire thus creating more efficient fire. Numeral
118 shows the large oval holes in 104 the main fuel grate to
increase air flow to the fire which increases the efficiency of the
fire and to allow for ash to fall down into 108 the ash tray pan.
Numeral 120 shows the small circular holes in 104 the main fuel
grate to allow for even more airflow into the fire. 122 the rack
stop, is the device that keeps the fire box from sliding all of the
way out of the housing or oven. 400 the firebox has a generally
rectangular shape and is comprised of three walls and a large hole
in the front to allow for 100 the main fuel tray assembly to be
pulled out of.
[0019] Numeral 200 shows an exploded view of the fuel tray
assembly. The fire starter grate 202 sits inside of 102 the main
fuel tray and approximately three inches below 104 the main fuel
grate. 202 the fire starter grate is where kindling and other
suitable materials rest upon to ignite the fuel on 104 the main
fuel grate. Numeral 204 shows the pin holes in 202 the fire starter
grate to secure 202 to 206 the fire starter grate supports, and
then secured to 208 pin holes in the bottom of 108 the ash tray
pan. 210 the pin holes in 112 the mounting feet allow 114 the
mounting pin to slide through. 212 the pin holes in 102 the main
fuel tray also allows for 114 the mounting pin to slide through.
214 the pin holes in 108 that allows 114 the mounting pin to slide
through to secure the mounting to 112 the mounting feet, 108 the
ash tray pan, and 102 the main fuel tray so the components are all
secure as one piece. Numeral 216 shows the small circular holes in
202 the fire starter grate and allow for increased air flow into
the fire. 218 is the pin hole in 114 the mounting pin the secure
the mounting pin from sliding out. 400 is the firebox assembly.
