The screen or screening 200 may be removably attached to the flange 2g by the use of clips 210, 212, 214, 216, and one or more further clips, such as attached between devices 4 and 34, and between devices 24 and 34, not shown.

The screen or screening 200 may be the same type of material as used for known fireplace screens.

FIG. 6 shows a front, top, and right side perspective view of the apparatus 1 of FIG. 1 along with the two logs 102 and 104 shown placed in an inner chamber 52 of the second device 50 of FIG. 3, along with screening 200 attached, which screens the region between the first device 2 and the second device 50, and wherein the second device 50 is shown placed on one or more supports 250, 252, and 254, and one or more further supports not shown. There typically would be at least four supports, which may define vertices of a rectangular shape. Each of the supports 250, 252, and 254, may be a brick or a stone, or other non flammable rigid support structure.

The screen 3 or spark screen may be changed to a larger version.

In at least one embodiment, there will also be a removable plate mounted in the front of the upper tray so you can see the flame-light through a logo that will be cut into the plate.

The base supports 250, 252, and 254, and any further base supports are constructed so that they are able to stop heat from traveling down to the ground surface 106, which could harm or set fire to a deck, or grass on the ground surface 106 in FIG. 6.

The screening 200, or spark arrester surrounding screen 200 may be made of hanging chain, chain mail, other material suited for high temp.

The second device 50 may hold firewood, such as logs 102 and 104 in inner chamber 52, as the logs 102 and 104 burn.

There may be an optional grill kit provided to cook, grill, or bake food, where would it be placed, show in pen marked up drawing.

A gas (natural/propane) kit may be provided with the apparatus 1.

The apparatus 1 and screening 200 may be used as a smoke box, to smoke meats.

The apparatus 1 and screening 200 may be used as a box with stone to cook pizza.

The beams, members or support columns 10, 20, 30, and 40 may be of different material and they may be attached or adhered to devices or trays 2 and 50 in various known ways. There can be more or less members or support columns.

An average wheelbarrow tray, such as preferably used for trays or devices 2 and 50, is heavy duty sixteen gauge (on average) high grade steel so apparatus 1 will last for many years.

The screen 3 is typically fixed, such as by screws, to upper tray 2 to provide safety. The screening 200 can be more easily removed such as by detachable clips, or may be able to be slid similar to a fire place screening or screening.

In one or more embodiments, a method provided, includes placing one or more combustible items in an inner chamber 52 of the wheelbarrow tray 50 of such an apparatus; and causing the one or more combustible items to ignite for which safety is provided by the utilization of the permanent spark arrestor screen 3 fastened to the top of the wheelbarrow tray 2 and spark arrestor screening 200 surrounding the wheelbarrow fire pit and/or inner chamber 52. The method to fasten the spark arrestor screening 200 surrounding the wheelbarrow fire pit and/or inner chamber 52 can change depending on configuration. The spark arrestor screen 3 on top of wheelbarrow tray 2 can be modified regarding, material, shape and size of screen and its surface area coverage depending on configuration.

Although the invention has been described by reference to particular illustrative embodiments thereof, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. It is therefore intended to include within this patent all such changes and modifications as may reasonably and properly be included within the scope of the present invention's contribution to the art.
