Abstract
A quick start barbecue comprises a kettle, column and base. A moveable charcoal grate, when lowered into the column, folds into a basket shape thereby holding the charcoal in a compact configuration ideal for starting. Once the charcoal has ignited the grate is lifted into the kettle and in the process unfolds into a flat shape with the charcoal evenly distributed in a configuration ideal for cooking. The charcoal may be started using crumpled newspaper placed below the charcoal grate in its lower “basket” position or by use of a self igniting propane torch removably affixed to the column. A long chimney may be placed in the kettle to aid starting and stored around the column. A removable ash drawer in the base makes cleanup easy. Removal of the ash drawer causes a gate to close so that excess ash is confined to the column while the drawer is out.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to barbecues for cooking, and more particularly to barbecues of the type in which charcoal in briquette or similar form is used as the source of heat for the barbecue.
2. History of the Prior Art
Barbecues which use charcoal in briquette or similar form as the source of cooking heat are well known. Charcoal fueled barbecues provide the advantage that a gas hookup or, alternatively, a large and cumbersome propane tank, are not needed. In particular, charcoal barbecues are ideally suited for remote outdoor locations such as for picnics. Many such barbecues are portable and light weight, enabling them to be transported, such as by car, to the location where they are to be used for cooking. Upon setup of the barbecue, a desired quantity of charcoal is loaded into the barbecue and is ignited, causing the charcoal to burn. When the charcoal is capable of generating sufficient cooking heat, the food to be cooked is typically placed on a cooking grate disposed above the charcoal. When the cooking is finished, the ash generated by the burnt charcoal is disposed of in preparation for the next use of the barbecue.
One problem with charcoal barbecues is getting the charcoal to start and burn quickly so that cooking may commence without substantial delay. To accelerate the process of starting the charcoal, a number of arrangements and techniques have been devised. Typically, the charcoal is ignited while confined in a small container so as to concentrate the heat in a small volume. The charcoal may, for example, be placed in a can-shaped structure positioned above an igniter. When the charcoal is ready for cooking, it is typically spread onto a charcoal grate beneath the cooking grate. In some cases the can-like structure is lifted and turned upside down so as to dump the charcoal onto the charcoal grate, as shown, for example, by U.S. Pat. No. 5,469,835 of Stephen et al. In still other cases, mechanisms are provided for spreading the charcoal from the can-like structure onto the charcoal grate, as shown, for example, by U.S. Pat. No. 4,603,679 of Ogden, and by U.S. Pat. No. 5,638,807 of Flamenbaum. However, such arrangements leave much to be desired in terms of the lack of ease with which the charcoal can be ignited and initially burned while in a small and confined container and then easily spread onto a charcoal grate.
In U.S. Pat. No. 5,154,159 of Knafele, for example, the charcoal is started on an elevator platform which is then raised to a charcoal grill. However, the platform must then be rotated in order to distribute the charcoal over the separate and much larger charcoal grill.
In some cases, a chimney may be provided over the charcoal container in order to promote convection and cause the charcoal to burn faster. Such chimneys must be removed when not in use, typically requiring that they be separately carried and stored.
The charcoal is typically ignited using newspaper or other disposable flammable material. Sheets of newspaper are wadded up and placed under the charcoal. The paper is then set on fire using a match, and the burning paper ignites the charcoal. Paper ignition is shown by U.S. Pat. No. 3,209,743 of Stewart and U.S. Pat. No. 3,841,299 of Tomita. Still other forms of charcoal ignition such as a propane igniter may be used. In any case, however, it would be desirable to provide an arrangement in which paper can be used as the ignition source and, alternatively, in which a propane igniter can be readily coupled to the barbecue to serve as the ignition source.
Disposal of the residual ash and unburned portions of the charcoal after the cooking is finished can be a further problem. Simply turning the barbecue over and dumping the ash and charcoal residue can be cumbersome and messy, if not a fire hazard. Therefore, some barbecues are provided with an ash fallout system as shown, for example, by U.S. Pat. No. 3,915,145 of Tomita. Still others provide an ash drawer or other collection apparatus at the bottom thereof, as shown, for example, by U.S. Pat. No. 5,996,572 of Hagan. The barbecue is desirably designed so that ash and unburned portions of the charcoal fall down into the ash drawer. This may require open passageways from the charcoal grate down to the ash drawer so that the ash may fall down into the drawer unimpeded. In this connection it would be desirable to be able to scrape and otherwise manipulate the charcoal grate and the inner walls of the kettle or other cooking chamber at the top of the barbecue so as to agitate and dislodge the ash and charcoal and cause it to fall down into the ash drawer.
The ash drawer itself should desirably be designed so that the bottom of the barbecue just above it is closed off and sealed when the ash drawer is removed for disposition of its contents. When the drawer is again installed, the area above the drawer must be opened so as to receive the falling ash.
BRIEF DESCRIPTION OF THE INVENTION
Briefly stated, the present invention provides a quick start barbecue which has a housing with a cooking compartment therein and a cooking grate mounted in the cooking compartment. A foldable charcoal grate is positioned below the cooking grate and is movable between a lower position in which the charcoal grate folds to form a basket for charcoal and an upper position in which the charcoal grate unfolds to form a relatively flat grate for charcoal beneath the cooking grate. An actuator mechanism selectively moves the charcoal grate between the lower and upper positions. Igniting apparatus mounted below the charcoal grate ignites charcoal contained within the charcoal grate while it is in the lower position.
With the charcoal grate folded to form a basket in the lower position, the basket is filled with charcoal and the igniting apparatus is used to light the charcoal. When the charcoal is sufficiently hot and ready for cooking, the actuator mechanism is used to raise the charcoal grate to the upper position in which it unfolds so as to form a relatively flat grate for the charcoal beneath the cooking grate. Cooking may then be carried out.
The charcoal grate may comprise a central hub with a plurality of wire loops configured like flower petals pivotally coupled thereto and extending outwardly therefrom in a circular array. The petals pivot upwardly relative to the hub to form a basket for the charcoal, and pivot downwardly and outwardly relative to the hub to form a relatively flat grate for charcoal. The hub has a plurality of spokes extending outwardly in a circular array. Each of the petals is generally U-shaped, although not necessarily with straight legs, and is pivotally coupled at the free ends of the “U” to an adjacent pair of the hubs spokes.
The housing may comprise a kettle forming the cooking compartment and an upstanding column coupled to an opening into a lower portion of the kettle at a juncture therewith. The charcoal grate is positioned central to the vertical axis within and vertically movable between a position within the kettle and a position within the upper end of the column adjacent the juncture of the column with the kettle. The petals of the charcoal grate are contained within the column and form a basket for the charcoal when in the lower position. The petals pivot downwardly and outwardly relative to the hub as the charcoal grate is raised into the bottom of the kettle, to form a relatively flat grate for charcoal. The outer ends of the petals engage and reside against an inner wall of the kettle as the charcoal grate is raised into the bottom of the kettle, so that the vertical position of the hub of the charcoal grate within the bottom of the kettle determines the pivoting orientation of the petals relative to the hub.
The actuator mechanism may comprise a shaft centrally disposed and vertically movable within the column and with the hub mounted on an upper end thereof. The actuator mechanism includes an actuating handle coupled to a lower end of the shaft and extending to the outside of the column. The actuator mechanism includes lower and upper stops for the actuating handle, so that the charcoal grate is positioned in the lower position when the actuating handle engages the lower stop and in the upper position when the actuating handle engages the upper stop. The actuator mechanism also includes a rod disposed within a hollow interior of the shaft and fixed at its lower end to the housing. A coil spring is disposed within the hollow interior of the shaft and provides a lifting force to the charcoal basket while it is in the lower position.
The igniting apparatus comprises at least one access hole in the column which provides access to the space within the column and below the charcoal in the basket. The access hole permits wadded up paper to be inserted therethrough and ignited to light charcoal positioned thereabove within the charcoal grate. A platform or basket holds the paper close to the underside of the charcoal basket. The access holes may also function as vent holes to allow ingress of air. The igniting apparatus may also include a propane torch igniter having a bracket detachably coupled to the housing at the access hole and having a nozzle which extends through the access hole to direct flame to the charcoal in the charcoal grate. The bracket has an upper hook and a lower tab respectively extending into upper and lower portions of the access hole to attach the bracket to the housing. The upper hook has a lip portion engaging an inner surface of the housing. Installation of the propane igniter is easily accomplished by inserting the upper hook of the bracket into the upper portion of the access hole so that the lip portion thereof engages the inner surface of the housing, and then lowering the propane igniter so that the lower tab is seated within a lower portion of the access hole. Removal of the propane igniter involves a reverse action in which the propane igniter is raised to remove the lower tab from the lower portion of the access hole, following which the lip portion of the upper hook may be disengaged from the inner surface of the housing to permit removal of the propane igniter.
The barbecue includes an ash drawer mounted at the bottom end of the column for collecting ash from the charcoal grate and from the cooking compartment. The charcoal grate is rotatable and vertically movable to dislodge ash therefrom and from the inner surface of the kettle allowing it to settle into the ash drawer. The rotational and vertical movement of the cooking grate allows safe and easy distribution of the charcoal for cooking when the charcoal grate is raised.
The barbecue may include a pair of shells pivotally joined by a handle assembly and positionable for storage on the outside of the column. The pair of shells are removable from the outside of the column and joinable together to form a chimney mounted in the lower portion of the kettle at the juncture with the column. The handle assembly is spring loaded to normally bias the pair of shells together onto the outside of the column. When the pair of shells are removed from the outside of the column and joined together and mounted in the lower portion of the kettle at the juncture with the column, they form a chimney above the charcoal basket. Such chimney, which is substantially tubular, serves to draw air through the charcoal due to convection which causes the charcoal to ignite faster. The shells are pivotably coupled along a first edge of each, and the handle assembly comprises a pair of handles, each mounted on a different one of the pair of shells adjacent the first edge thereof. The handle assembly includes a spring coupled to each of the pair of handles for biasing the pair of shells into a closed position in which second edges of each shell opposite the first edge thereof are joined together. The second edges of the pair of shells are provided with a tongue and groove interlock.
In addition to the ash drawer, the barbecue preferably includes a gate mounted within the housing above the ash drawer such that the gate is closed to close off the bottom of the lower end of the column whenever the ash drawer is removed from the lower end of the housing. A lift bar coupled to the housing beneath the ash drawer holds the ash drawer against the lower end of the housing to seal off the bottom of the lower end of the housing when the ash drawer is installed in the lower end of the housing. The gate has downwardly projecting front and rear lips. The front lip is contacted by the ash drawer to close the gate upon removal of the ash drawer. The rear lip is contacted by the ash drawer to open the gate upon installation of the ash drawer in the lower end of the housing.

DETAILED DESCRIPTION
FIG. 1
shows a quick start barbecue
10
according to the invention. The barbecue
10
has a housing which includes a kettle
12
at the top, forming a cooking chamber. The kettle
12
has a removable lid
14
to provide access to the interior thereof. The kettle
12
is mounted at the upper end of a column
16
extending downwardly from the kettle
12
to a base
18
at a lower end thereof. The column
16
is partially conical in shape so as to have a diameter which increases gradually from a lower end
20
thereof at the base
18
to an upper end
22
thereof at a juncture with the kettle
12
.
The column
16
has an access hole
24
in a side thereof. As described in detail hereafter, the access hole
24
provides access to a paper basket
50
inside of the column
16
so that newspaper or other combustible material can be inserted through the hole and ignited to start the charcoal within the barbecue
10
. The access hole
24
also functions as a vent allowing air to enter the column and rise through the charcoal. A vent covers
54
slidably engages the inside of the column
16
to cover or uncover the access/vent holes
24
. The vent cover
54
and a vent in the lid
14
(not shown) are closed after cooking is finished in order to smother the charcoal.
Also visible in
FIG. 1
is an actuating handle
26
extending outwardly through a recess
28
in the side of the column
16
. The actuating handle
26
forms part of an actuator mechanism
30
which functions to raise and lower a charcoal grate within the barbecue
10
, as described in detail hereafter. The recess
28
is provided with lower and upper stops
32
and
34
. The lower and upper stops
32
and
34
engage the actuating handle
26
to position the handle
26
in lower and upper positions, respectively. The actuating handle
26
is shown in an uppermost position in engagement with the upper stop
34
, in FIG.
1
.
Also shown in
FIG. 1
is an ash drawer
36
which is mounted within the base
18
. The ash drawer
36
which is shown in
FIG. 7
is described hereafter in conjunction with a gate within the base
18
which is shown in
FIGS. 8A-8C
but which is not shown in FIG.
1
.
FIG. 2
is a sectional view of the barbecue
10
of FIG.
1
. In
FIG. 2
, the lid
14
is removed from the kettle
12
, and a chimney
38
is installed within the kettle
12
at the juncture of the bottom of the kettle
12
with the upper end
22
of the column
16
. The chimney
38
, which is shown and described in detail in connection with
FIG. 3
is comprised of a pair of opposite, hinging shells which close together to form the tubular chimney
38
. The chimney
38
is normally stored on the outside of the column
16
, except when in use as shown in FIG.
2
. The opposite shells of the chimney may be separated against spring resistance to enable placement around the column
16
for storage thereon.
As shown in
FIG. 2
, the barbecue includes a charcoal grate
40
which includes a central hub
42
having a plurality of petals
44
pivotally coupled thereto. The charcoal grate
40
is shown and described in greater detail in connection with FIG.
4
. In the position of the charcoal grate
40
shown in
FIG. 2
, the petals
44
are pivoted upwardly relative to the hub
42
to form a basket
46
for charcoal when in such lower position.
With the charcoal grate
40
in the lower position so as to form a charcoal basket
46
, as shown in
FIG. 2
, the basket
46
may be filled with charcoal. The charcoal is ignited using igniting apparatus
48
which includes a paper basket
50
which is a platform to hold combustible material such as newspaper close to the charcoal to be ignited.
The paper basket
50
may be used to ignite a quantity of charcoal located in the basket
46
formed by the charcoal grate
40
. Sheets of newspaper or other similar flammable material are wadded up and inserted through the access holes
24
onto the paper basket
50
. Matches may then be used to ignite the paper which in turn ignites and starts the charcoal within the basket
46
formed by the charcoal grate
40
.
The igniting apparatus
48
alternatively includes a propane igniter
58
which includes a liquid propane (LP) tank
60
coupled to a bracket
62
having a nozzle
64
extending therefrom. Note that the propane igniter
58
in
FIG. 2
is shown opposite the recess
28
for illustrative purposes only. The bracket
62
has an upper hook
66
which extends therefrom and has a lip portion
68
. The bracket
62
also has a lower prong
70
extending therefrom.
To install the propane igniter
58
on the barbecue
10
, the upper hook
66
of the bracket
62
is first inserted into an upper portion of the access hole
24
where the lip portion
68
thereof is engaged with the inside of the column
16
. The propane igniter
58
is then lowered so as to insert the lower prong
70
into a lower portion of the access hole
24
, until the bracket
62
is seated against the outside of the column
16
. Propane gas from the tank
60
is ignited, and forms a flame at the nozzle
64
. This ignites and starts a quantity of charcoal loaded within the basket
46
of the charcoal grate
40
. The propane igniter
58
may have a sparking device
59
to light the propane.
The propane igniter
58
is easily removed from the barbecue
10
simply by reversing the installation procedure. The propane igniter
58
is rotated upwardly so as to remove the lower prong
70
from the lower portion of the access hole
24
. This enables the upper hook
66
with its lip portion
68
to be disengaged from and removed from the access hole
24
, thus completing removal of the propane igniter
58
from the barbecue
10
.
The charcoal grate
40
is positioned using the actuator mechanism
30
. As shown in
FIG. 2
, the actuating handle
26
is coupled to a hollow shaft
72
which extends upwardly from the actuating handle
26
to an upper end thereof which is coupled to the central hub
42
of the charcoal grate
40
. The upper end of the hollow shaft
72
extends through a bushing
74
fixedly mounted to the column
16
. A substantially cylindrical heat shield
76
is fixedly mounted inside the upper end of the column
16
. The bushing
74
permits vertical movement of the hollow shaft
72
therethrough.
The bottom end of the rod
78
is mounted to a wall
80
of the recess
28
. The rod
78
extends through the interior of the hollow shaft
72
. The top of the rod
78
serves as a mounting point for the upper end of extension coil spring
82
. The lower end of the coil spring
82
provides a lifting force to the shaft
72
and thus the charcoal grate
40
in order to move the charcoal into the cooking position.
With the charcoal grate
40
positioned in its lowermost position with the actuating handle
26
engaging the lower stop
32
, as shown in
FIG. 2
, the charcoal grate
40
resides just above the bushing
74
, and the coil spring
82
is in an extended state. As described in detail hereafter, the actuating handle
26
is disengaged from the lower stop
32
and is raised along the recess
28
, moving the hollow shaft
72
upwardly through the bushing
74
so as to raise and gradually unfold the charcoal grate
40
until eventually the charcoal grate
40
forms a relatively flat grate and the charcoal is positioned inside the kettle
12
just below a cooking grate. This feature in accordance with the invention enables the charcoal to be readily transported upwardly into a location where it is ready for use on a relatively flat grate. This is made possible by the charcoal grate
40
which folds to form the basket
46
when in the lower position and which unfolds to form a relatively flat grate when in the upper position. When the charcoal grate
40
is in the lowermost position as shown in FIG.
2
and forms the basket
46
, charcoal loaded into the basket
46
and ignited by the igniting apparatus
48
starts and burns very quickly by being held in a confined manner and being subject to an updraft due to convection. The chimney
38
further serves to increase the convection and accelerate the process of igniting the charcoal. When the coals are ready for cooking, the chimney
38
is removed from the kettle
12
and set aside. Using the actuating handle
26
, the charcoal grate
40
is then raised into the bottom of the kettle
12
, where it unfolds into a relatively flat grate for holding the charcoal beneath a cooking grate within the kettle
12
. The actuating handle
26
may be moved rotationally and vertically to evenly distribute the charcoal for cooking.
The chimney
38
is shown in FIG.
3
. As shown therein, the chimney
38
is comprised of opposite mating shells
84
and
86
pivotably coupled along a first edge of each at a pivot joint
88
. A spring-loaded handle assembly
90
includes a pair of handles
92
and
94
coupled to the first edges of the shells
84
and
86
respectively. As shown in
FIG. 3
, the handles
92
and
94
form a convenient means of grasping the shells
84
and
86
to transport the chimney
38
between the outside of the column
16
and the inside of the kettle
12
. A spring
96
attached to and extending between the handles
92
and
94
normally biases the shells
84
and
86
into a closed position in which second edges of the shells
84
and
86
opposite the first edges are joined together. The second edges of the shells
84
and
86
are provided with a groove
98
and a tongue
100
, respectively, for interlocking engagement when the shells
84
and
86
are closed together.
By simply squeezing the handles
92
and
94
together, against the resistance of the spring
96
, the opposite shells
84
and
86
pivot into the open position. Because the handles
92
and
94
are relatively close to each other, it is possible using a single hand to grasp both handles
92
and
94
and squeeze them together to open the shells
84
and
86
, while at the same time removing the shells
84
and
86
from the outside of the column
16
. By releasing some of the pressure on the handles
92
and
94
, the opposite shells
84
and
86
then join together under the urging of the spring
96
, and the chimney
38
formed by the shells
84
and
86
may then be placed within the kettle
12
in the position shown in FIG.
2
. When it is desired to remove the chimney
38
from the kettle
12
, the handles
92
and
94
are grasped and the shells
84
and
86
are lifted out of the kettle
12
. By then squeezing the handles
92
and
94
toward each other, the shells
84
and
86
open sufficiently so that they may be placed over the outside of the column
16
. When the handles
92
and
94
are released, the urging of the spring
96
biases the opposite shells
84
and
86
toward one another to hold them in place on the outside of the column
16
.
FIG. 4
is a detailed view of the charcoal grate
40
. As shown therein, the central hub
42
includes a plurality of spokes
102
which extend outwardly in a circular array. Each of the petals
44
is comprised of a generally U-shaped element having opposite pairs of legs
104
and
106
pivotably coupled to an adjacent pair of the spokes. Each leg
104
and
106
is coupled to one of the spokes
102
by a pivot pin
108
. The ends of each petal may be squeezed together as indicated to assemble the grate at the factory or for the user to replace individual petals.
The pivot pins
108
enable the petals
44
to undergo pivoting movement relative to the spokes
102
of the hub
42
. When the charcoal grate
40
is in its lowermost position shown in
FIG. 2
, the petals
44
are pivoted upwardly relative to the hub
42
to form the basket
46
for the charcoal. As the charcoal grate
40
is then raised from this position, the petals
44
swing downwardly relative to the hub
42
until they form a relatively flat charcoal grate with the hub
42
, as described hereafter.
FIG. 5
is a cross-sectional view of the barbecue
10
with the charcoal grate
40
raised somewhat from its lowermost position in FIG.
2
. This action is brought about by disengaging the actuating handle
26
from the lower stop
32
and moving it upwardly. Such action slides the hollow shaft
72
upwardly along the rod
78
. This movement is aided by tension coil spring
82
residing within the hollow shaft
72
. The hollow shaft
72
moves upwardly through the bushing
74
, raising the hub
42
of the charcoal grate
40
above the bushing
74
and the bottom of the heat shield
76
.
As previously described, the upper end
22
of the column
16
forms a juncture with an open lower end of the kettle
12
. As the charcoal grate
40
is raised, the petals
44
slide along the juncture
110
until the hub
42
of the charcoal grate
40
begins to enter the lower open end
110
of the kettle
12
. When this happens, the petals
44
are free to pivot downwardly relative to the hub
42
by a substantial amount so as to begin to open up the basket
46
previously formed by the charcoal grate
40
. As shown in
FIG. 5
, the petals
44
are in a partially opened position.
As also shown in
FIG. 5
, a cooking grate
112
is mounted within the kettle
12
just below the lid
14
of the kettle. Food placed on the cooking grate
112
is cooked by the charcoal when the charcoal grate
40
is raised into its uppermost position, as described hereafter.
FIG. 6
is a cross-sectional view of the barbecue
10
similar to that of
FIG. 5
, but with the charcoal grate
40
raised to its uppermost position. The actuating handle
26
has been raised into engagement with the upper stop
34
, and the coil spring
82
is relaxed even further compared with the case in FIG.
5
. The hollow shaft
72
is moved still further into the bottom of the kettle
12
, allowing the petals
44
to pivot downwardly even further so that they combine with the hub
42
to form a relatively flat grate for the charcoal.
FIG. 6
shows a quantity of charcoal on the charcoal grate
40
. The charcoal is positioned below the cooking grate
112
in a desired position for cooking food placed upon the cooking grate
112
.
As the charcoal burns and ash begins to form, the open spaces within the charcoal grate shown in
FIG. 4
permit such ash to fall through the charcoal grate
40
into the upper open end of the column
16
. The bottom of the heat shield
76
is open, allowing such ash to fall therethrough to the lower end
20
of the column
16
. The lower end
20
of the column
16
has an opening
114
therein, through which the ash falls into the ash drawer
36
within the base
18
. In this fashion, the ash drawer
36
continues to collect ash which falls from the charcoal grate
40
as the cooking process proceeds. Eventually, the ash drawer
36
is removed from the base in order to permit disposal of the ash therein.
After cooking is completed, if partially burned charcoal remains on the charcoal grate
40
, the charcoal grate
40
can be rotated and raised and lowered to a limited extent by manipulating the actuating handle
26
, thus sifting ash from the remaining unburned charcoal. The ash falls through the column
16
and into the ash drawer
36
. An arrow
116
shown in
FIG. 5
illustrates such rotational and vertical motion of the actuating handle
26
to rotate and dislodge ash from the charcoal grate
40
.
If ash has collected on the bottom of the kettle
12
, the charcoal grate
40
can be lowered part way and then rotated to dislodge the ash, allowing it to fall through the column
16
and into the ash drawer
36
below. Lowering the charcoal grate all the way causes the petals
44
to pivot upwardly to the extent that they form the basket
46
. When the barbecue
10
is next used, charcoal is poured into the basket
46
at lease up to the juncture
110
of the column
16
and the kettle
12
.
The ash drawer
36
is shown in FIG.
7
. As shown therein, the drawer
36
is of generally rectangular configuration and has an open upper end
118
through which the ash falls for deposit within the drawer
36
. The front end of the ash drawer
36
has a curved face
120
which fits flush with the base
18
of the barbecue
10
when the ash drawer
36
is in the closed position. An opening
121
facilitates grasping thereof for outward pulling to remove the ash drawer
36
from the base
18
of the barbecue
10
.
FIG. 8A
shows the ash drawer
36
in the closed position within the base
18
. As such, the opening
114
at the bottom of the column
16
communicates with the upper open end
118
of the ash drawer
36
so that ash descending through the column
16
is free to fall into and deposit within the ash drawer
36
. The ash drawer
36
is designed to hold at least two uses worth of ash. However, the lower end
20
of the column
16
is capable of storing still more ash, up to the bottom edges of the access holes
24
. A lift bar
122
mounted within the base
18
at the bottom thereof resides against the bottom of the ash drawer
36
. The lift bar
122
serves to hold the ash drawer
36
against the structure at the lower end
20
of column
16
at the opening
114
therein. This provides an air seal, which is required in order to smother the charcoal.
The ash drawer
36
operates in conjunction with a gate
124
. As shown in
FIG. 8A
, the gate
124
is in an open position when the ash drawer
136
is in the closed position within the base
18
. This leaves the bottom end of the column
16
open so that ash falling through the column
16
can fall freely into the ash drawer
36
. However, opening of the ash drawer
36
causes the gate
124
to close off the open lower end of the column
16
, thereby preventing ash from falling onto the floor or ground beneath the barbecue
10
when the ash drawer
36
is removed. The gate
124
has downwardly hanging front and rear lips
126
and
128
.
As shown in
FIG. 8B
, as removal of the ash drawer
36
is begun, a rear portion of the ash drawer
36
contacts the front lip
126
of the gate
124
. Further outward movement of the ash drawer
36
slides the gate
124
into the closed position so as to close off the open lower end of the column
16
. In this position, the closed gate
124
prevents ash from falling from the column
16
onto the ground or floor below the barbecue
10
. Once the ash drawer
36
passes the lift bar
122
, the back end thereof may drop so as to clear the front lip
126
, thereby permitting removal of the ash drawer
36
from the base
18
.
Upon reinsertion of the ash drawer
36
, the rear edge thereof first passes under the front lip
126
of the grate
124
. Upon further insertion, the rear portion of the ash drawer
36
is lifted by the lift bar
122
. As the ash drawer
36
is moved into the closed position, the rear edge thereof engages the rear lip
128
of the gate
124
, thereby sliding the gate
124
into a position in which the bottom end of the column
16
is again opened and the opening
114
at the lower end
20
of the column
16
communicates with the upper open end
118
of the ash drawer
36
.
The front lip
126
of the gate
124
is spring loaded so that if the front lip
126
is contacted by the drawer
36
as the drawer is being withdrawn, it will cause the gate
124
to close, but if the front lip
126
is contacted by the drawer
36
as the drawer
36
is being inserted, the front lip
126
will flex, allowing the rear edge of the drawer
36
to bypass the front lip
126
.
