Double-pit outdoor grill

Abstract

A double-pit outdoor grill with consists of two more or less symmetrical cooking chambers joined to form a common wall. The common wall between the two chambers have openings which permit the flow of heat/air from the lower chamber through to the upper chamber with same exiting the upper chamber by way of a centrally located stack. The lower chamber has an air intake located along the forward and bottom mid-section of the chamber, allowing air to draft in along the bottom of the lower chamber which is used to burn wood or similar cooking materials. Either through the natural draw of air or with the assistance of a high temperature furnace fan, which can be situated either over the stack of the upper compartment [resulting in a draw of air through the upper and lower compartments] or fixed in front of the lower compartment air intake (acting as a forced air device, pushing air from the lower compartment through the cooking fuel and into the upper compartment), temperature can be increased and/or the combustion process accelerated. The two symmetrical upper and lower chambers are joined by their aft walls, each running the same width which produces a fire box and confection oven, thus allowing for the even distribution of heat from the fire box to the confection oven. The symmetrical design of the two chambers further permits both cooking chambers to be used simultaneously, one as an oven cooker, and the second is a direct fire pit. Symmetry of the items allows for even distribution of heat from the fire box to the oven, and the placement of the upper and lower chambers, allows for air to draw in through the lower, fire box, and follow its natural path of rising and exiting through the upper oven box. The chambers may be mounted to fixed legs or, as shown in the working model, to a double trailer.

1 . A cooking device which consists of two more or less symmetrical cooking chambers placed fore and aft of the back wall of each chamber joined to form a common wall.  
   
   
       2 . A cooking device where the two chambers are arranged such that one is located with its base 50% of the distance up from the base of the second chamber creating an upper and lower chamber, both being more or less symmetrical compartments.  
   
   
       3 . A cooking device as described in  1  and  2  above and with a common wall between the two chambers have openings which permit the flow of heat/air from the lower chamber through to the upper chamber with same exiting the upper chamber by way of a centrally located stack.  
   
   
       4 . A cooking device as described in  1 ,  2  and  3  above and where the lower chamber has an air intake located along the forward and bottom mid-section of the chamber, allowing air to draft in along the bottom of the lower chamber which is used to burn wood or similar cooking materials.  
   
   
       5 . A cooking device as described in  1  through  4  above and where either through the natural draw of air or with the assistance of a high temperature furnace fan, which can be situated either over the stack of the upper compartment [resulting in a draw of air through the upper and lower compartments] or fixed in front of the lower compartment air intake (acting as a forced air device, pushing air from the lower compartment through the cooking fuel and into the upper compartment), temperature can be increased and/or the combustion process accelerated, or where two fans are used in conjunction with each other.  
   
   
       6 . A cooking device as described in  1  through  5  above and where the two symmetrical upper and lower chambers are joined by their aft walls, each running the same width which produces a fire box and confection oven, thus allowing for the even distribution of heat from the fire box to the confection oven.  
   
   
       7 . A cooking device as described in  1  through  6  above and where the symmetrical design of the two chambers further permits both cooking chambers to be used simultaneously, one as an oven cooker, and the second is a direct fire pit.  
   
   
       8 . A cooking device as described in  1  through  7  above and whereby following the basic principles of symmetry and box orientation, the cooking chambers may be constructed larger or smaller than the working model.
