Abstract

The barbecue, when assembled, comprises three sections; a raised base (7) and two truncated cones (12, 13). These fit together to form the chimney of the stove. The meat to be grilled is placed in a wire mesh cap (14) which sits on top of the chimney. Holes (18) drilled in the base and upper section of the assembly provide the air flow necessary to produce combustion of the balled up paper fuel. Fat, dripping onto the fuel from the meat being grilled, provides the means of sustaining combustion until cooking is completed. The barbecue is compact and lightweight and when not in use can be stowed in a relatively small package making it easily portable. <IMAGE>

Description

PEAK-FEAST RARBEGUE THIS BARBECUE relates to a stove for cooking meat and the like , particularly at picnics and similar outdoor functions.

It is sometimes difficult to find suitable fire places and obtain the necessary fuel when it is desired to grill meat out of doors, also there is frequently danger and inconvenience associated With open tires It is an object of this barbecue to provide a special form of stove whereby the above mentioned difficulties are avoided.

Further objects of this barbecue are to provide an efficient lightweight stove which can be easily assembled and readily collapsed for packing and transportation.

In accordance with this barbecue there is provided a transportable grilling stove built of sheet metal and of bucket-like shape, having feet and holes in the bottom providing ventilation suitably limited to allow a few sheets of crumpled paper to serve as an initial fuel for grilling fatty meats and thereafter to allow the paper to form a charred base on which fat dropping from the meats can burn effectively to continue the grilling operation.

The barbecue provides also for a cap in the form of two layers of a metal wire mesh hinged together; for said cap to have handles extendible with a sliding action; for the stove to be built of fitted sheet metal cylindrical sections and for additional ventilation holes to be provided round the cylindrical part of the stove.

By way of example a preferred form of stove according to this barbecue suitable for use at a small picnic will be described.

Fig. 3 is an assembly of the parts for transport.

Fig. 4 is a cover open to receive the food to be grilled.

Fig. 5 the cover as shown in Fig. 4 folded for transport.

Fig. 6 a plan of the bottom of the barbecue showing a convenient distribution of the ventilation holes.

In the example illustrated the barbecue is made of mild steel sheet about 26 to 94 Birmingham Wire Gauze and its approximate sizes are as follows: The bottom or bucket section 7 is spun to form a flat bottom dish 3#" high, 9" diameter at bottom 8 and 9#" diameter at top 9. The bottom 8 has feet 10 welded on to lift it to l" to 2".

The bottom 8 has 16 - 3/16" holes distributed over the area, conveniently on four radii.

The barbecue is in three sections each having te shape of an inverted truncated cone. The bottom one 7 is adapted to have the smaller 12 of the cones fitting into it a small way, and the larger one 13 of the truncated cones fits a small way into the top of the smaller cone 12, as shown in Flg. 1. These two conical sections 12 and 13 have the following approximate dimensions respectively; both are 5" high and 12 is 9#" at the bottom and 10# diameter at the top. 13 is 10#" diameter at the bottom and 11" at the top.When fitted together, fn the way described, the barbecue has an overall height ol approximately 13".

Two flat pieces 14 or metal wire mesh, Figs. 4 and 5 about 10" in diameter are hinged together and provided with metal projecting lugs 15. This forms a loose fitting cap or cover for the top of the stove. Each piece 14 has a long U-shaped wire 15 adapted to be slid radially outwardly to form a handle e (Fig. 4.). The food to be grilled is conveniently placed between the two parts 14 of the cover and when the stove is burning they are turned over from time to time for the food to become properly grilled. Care must be taken not to over-crowd the top but to leave room for the heated air to escape readily from the top of the barbecue.If the cap is raised too far above the top of the stove air can pass underneath and the food is liable to be burnt.

In use this barbecue has heen constructed to function when crumpled newspaper only is used as initial fuel.

Three or four sheets of newspaper are lightly balled up, dropped onto the bottom of the stove as shown in dotted lines 17, Fig. l, and ignited. This is the initial fuel; normally the fat dropping from the meat, which, almost immediately begins to fall, augments the newspaper fuel 17 and the heat provided by the fat carried and burning on the charred paper is sufficient to complete the grill.

It will be noted that the holes 11 in the bottom 8 are well spread and are only 3/16" in diameter. Usually there are only 16 of them so that they provide a total area of .4416 square inches. Around the lower portion of the second cone 12 are some 20 holes 1d, these also are 3/16" in diameter which give a total area of .552 square inches. This means that a total area of all these 5/1,5 inch holes is just under a square inch, and through this small area the air must pass to a fire at the bottom of a chimney l3" high and formed by the bucket. The area of the chimney has an average of not less than 78.54 square inches. It might be thought that combustion would be damped due to restriction of air, but as the amount of ventilation has been regulated a balance is obtained in the amount of air allowed to pass into the stove. Ton much air would burn up the paper too rapidly and burning fragments would be blown out of the barbecue or else reduced to such fine ash as to provide nothing on which the fat from the food could be supported while burning.

On the other hand too little air would not s support combustion of the paper or would produce a flame so weak that the fat from the food would not he melted and would not drop or if any did drop, theye would be insufficient air to produce a flame to complete the grilling. The few ventilation holes 18 serve to allow jets of a air to enter and these serve to complete the combustion and reduce the tendency for smoke to be formed.

From the description of this barbecue it will be realised that this provides a barbecue for g'-illing, fired hy only a few sheets of newspaper. At the end of the cooling there are no coals to throw out or smouldering embers to dampen. A little ash from burnt paper is all left. No grass or forest fires are lilrely to he started by accidental ignition emanating from the cooking operation, where this barbecue is used.

When the barbecue is to be packed for transport, the two cylindrical sections 12, 13 when separated, are nested one within the other, and the bottom section 7 lowered into them as shown in Fig. 3. The cap 14 as shown in Fig. 5 can be placed on top of the disassembled parts of the stove for packing purposes.
