DESCRIPTION 
1. Technical Field 
The present invention relates generally to outdoor cooking devices and, 
more particulary, to an improved ash catcher for a portable charcoal 
grill. 
2. Background of the Invention 
Charcoal grills have been in existence for several decades and usually 
consist of a lower chamber that has a supporting grid for supporting 
charcoal briquettes that are ignited to provide the heat for food 
supported on a cooking grid, located above the charcoal grid. Usually, 
this type of unit incorporates vent openings adjacent the bottom of the 
firebox for providing the necessary air for ignition and burning of the 
charcoal. The vent openings are also utilized for disposing of the ashes 
that accummulate in the bottom of the chamber. 
One of the more successful types of outdoor charcoal cooking units has been 
marketed for a number of years by the Assignee of the present invention 
and consists of a generally hemispherical upwardly-opening lower bowl 
which has a grid adjacent the bottom for supporting charcoal briquettes 
and a cooking grid located adjacent the upper rim of the bowl. A cover is 
usually removably supported on the rim of the bowl and the bowl has vent 
openings adjacent the lower portion, which not only provides the necessary 
air for combustion of the charcoal briquettes but also a means for 
discarding the ashes that accummulate in the lower portion of the bowl. 
The charcoal grill marketed by the Assignee of the present invention 
includes a tripod leg supporting structure consisting of three legs that 
are received in sockets that are connected to the outer surface of the 
bowl and define a generally triangular configuration for the supporting 
structure. 
The charcoal grill sold by the Assignee of the present invention also 
includes an ash catcher that is supported on the respective legs and the 
ash catcher is formed of a non-corrosive material, such as aluminum. The 
ash catcher has three generally L-shaped slots extending from the outer 
periphery which are adapted to receive the legs of the support structure 
so that the ash catcher can be manipulated into position by inserting the 
ends of the slots around the legs and than rotating the ash catcher so 
that the bases of the L-shaped slots receive the legs. 
Because of the lightweight construction of the particular types of ash 
catchers, difficulties have been encountered in maintaining the ash 
catcher in a fixed position, particularly under windy environments. 
Thus, the Assignee of the present invention has developed a 
specially-designed spring clip which has a circular portion surrounding 
and frictionally gripping the respective legs of the support structure and 
being located above the upper surface of the ash catcher to prevent the 
ash catcher from being raised and tilted during high wind conditions. 
While such an arrangement has been proven to be satisfactory for 
essentially fixedly-securing the ash catcher on the tripod leg 
arrangement, the manufacturer of this type of unit, as shown in U.S. Pat. 
No. 4,416,248, is constantly striving to reduce costs and increase its 
competitive position with respect to this type of grill. 
SUMMARY OF THE INVENTION 
According to the present invention, a new ash catcher has been developed 
which is easier to manufacture and results in a more sturdy structure than 
what has heretofor been known for units of the type. The grill consists of 
a lower hemispherical bowl supported on three legs that are arranged in a 
tripod configuration with a cover on the bowl and an ash catcher supported 
on the tripod leg structure. 
According to the primary aspect of the invention, the ash catcher consists 
of a generally circular disk that has a peripheral rim thereon which 
provides the necessary rigidity for the unit and the disk is moved 
upwardly from a lower position into engagement with each of the inner 
surfaces of the three leg structures to be wedged therein. A plurality of 
spring clips, equal in number to the leg structures, are supported on the 
legs and have inwardly-directed arms which are positioned below the ash 
catcher and act to maintain the ash catcher in the wedged position in the 
tripod leg structure. 
With this arrangement, the construction of the ash catcher is significantly 
simplified since the punching operation of providing the L-shaped slots is 
eliminated. Furthermore, the ash catcher is significantly more rigid since 
it is a one-piece structure that is still preferably formed of 
non-corrosive material that has a downwardly-directed rim around the 
periphery thereof. 
With the construction so far described, the ash catcher can be formed with 
a minimum amount of material, less than what was previously necessary, and 
the formation of the slots can be eliminated. Since the ash catcher has 
its periphery located within the triangular leg structure, a further 
reduction in materials is achieved over what was previously utilized by 
the Assignee of the present invention.

DETAILED DESCRIPTION 
While this invention is susceptible of embodiment in many different forms, 
there is shown in the drawings and will herein be described in detail a 
preferred embodiment of the invention with the understanding that the 
present disclosure is to be considered as an exemplification of the 
principles of the invention and is not intended to limit the broad aspect 
of the invention to the embodiment illustrated. 
FIG. 1 is a perspective view of a charcoal grill, generally designated by 
reference numeral 10, of the type that is disclosed in U.S. Pat. No. 
4,416,248, incorporated herein by reference. The grill 10 includes a 
generally spherical bowl 12 that has a cover 14 and is supported by three 
substantially identical legs 16 that are outwardly-inclined and arranged 
in a tripod configuration. Each of the legs is received into a socket 18 
that is secured to the periphery of the bowl 12. The cover 14 has vent 
openings (not shown) that are adapted to be opened and closed by a 
rotatable vent closure 20. The interior of the bowl has a charcoal grid 
supported adjacent the lower end thereof, which supports the charcoal 
above the bottom of the bowl so that air is drawn into the vent openings 
(not shown) to provide the proper combustion for the charcoal briquettes 
supported on the charcoal grid. A cooking grid (not shown) is located 
adjacent the peripheral rim of the bowl 12, as is more fully disclosed in 
the above-mentioned patent. 
The bowl 12 has elongated slots (not shown) that define vent openings which 
are adapted to be covered by generally inverted, V-shaped arms that are 
connected to a rotatable member which has a handle 22 secured thereto. As 
disclosed in the above patent, the handle may be manipulated to move the 
ashes collected in the bottom of bowl 12 towards the vent slots and an ash 
catcher 30 is provided for collecting the ashes that fall through the 
slots. As indicated above, in the prior art-type of charcoal grills 
utilizing the tripod leg structure support, the ash catcher is designed 
such that it can be releasably supported on the three legs through the use 
of three generally L-shaped slots which receive the legs. 
However, in practice, it has been found that because of the lightweight 
construction, the ash catcher has a tendency to move and vibrate under 
windy conditions and, in fact, under some conditions, may actually become 
detached from the leg structure. Furthermore, the ash catcher requires 
several production steps, including the stamping of the slots extending 
from the periphery. 
According to the present invention, a simplified ash catcher has been 
developed which can easily be assembled onto the tripod-type leg structure 
without any additional tools. The new ash catcher is constructed so as to 
be a one-piece unit that is rigidified around the periphery thereof by a 
flange or rim and is designed to be wedged into the tripod leg structure 
with supporting clips holding the ash catcher in the wedged position. In 
the illustrated embodiment, the supporting clips are in the form of a 
circular spring that surrounds each leg and frictionally grips the leg 
with the spring having a pair of arms that are grippable to release the 
clips from the legs and these arms also acts as the support for the ash 
catcher. 
As illustrated in FIG. 2, the ash catcher 30 comprises a generally circular 
dish or pan 32 that has a downwardly-directed peripheral rim or lip 34. 
The peripheral lip 34 is adapted to engage the inner surface of each leg 
and to be wedged in the tripod leg structure. 
The ash catcher is held in the wedged position by three spring clips 40 
respectively associated with the three legs. Each spring clip 40 includes 
a circular spring portion 42 and a pair of arms 44. The spring portion 42 
is adapted to encircle and frictionally grip the leg 16 and can be 
released by squeezing the arms 44. 
In assemblying the ash catcher, the three spring clips are initially 
positioned as shown in FIG. 2 below the final position for the ash 
catcher. The ash catcher is then wedged into position as shown in FIG. 2 
and the clip arms 44 are gripped and moved up into engagement with the 
lower side of the ash catcher to hold it in wedging engagement with the 
legs. 
In the assembled condition, the ash catcher is held in a fixed position and 
cannot move or vibrate during windy conditions. 
While the ash catcher has been shown associated with a tripod leg 
arrangement, the concept could also be adapted in a four leg support 
arrangement so long as the legs are inclined outwardly.
