Log stove and fire stand

Abstract

A log stove and fire stand are disclosed wherein the fire stand has a grill with three adjustable legs positioned over the log stove to complement the structural integrity of the burning log stove. The log stove may include a variable cross-section static air flow design and a ventilator gate that provide a method to inject excessive air (oxygen) flow into the combustion chamber throughout the burn cycle for complete fuel consumption. An excessive air volume to fuel ratio insures complete combustion of the billet thus reducing pollution.

We claim: 
     
         1 . A log stove compromising a log billet of combustible wood having a longitudinal axis, the log billet comprising:
 a combustion chamber extending into a top surface of the log billet substantially parallel to the longitudinal axis of the log billet, the combustion chamber comprising a generally cylindrical sidewall, a closed lower end and an open upper end;   a ventilator port comprising a passageway extending into the log billet from an outside surface of the log billet such that the ventilator port intersects the combustion chamber; and   a slot cut into the log billet, the slot extending transversely through the log billet from the outside surface of the log billet to the combustion chamber side wall, the slot comprising a upper end adjacent the top surface of the log billet and a lower end spaced apart from the top surface of the log billet, wherein the slot upper end has a first width and the slot lower end has a second width less than the first width;   wherein the width of the slot upper end is less than a diameter of the combustion chamber.   
     
     
         2 . The log stove of  claim 1  wherein the open upper end of the combustion chamber forms an exhaust port. 
     
     
         3 . The log stove of  claim 1  wherein the ventilator port has an axis that is perpendicular to a central axis of the combustion chamber. 
     
     
         4 . The log stove of  claim 1  wherein the ventilator port has a substantially cylindrical shape. 
     
     
         5 . The log stove of  claim 4  wherein the ventilator port has a substantially constant diameter. 
     
     
         6 . The log stove of  claim 1  wherein the ventilator port comprises a tapered hole. 
     
     
         7 . The log stove of  claim 6  wherein the ventilator port has a first diameter adjacent to log billet outside surface and a second diameter adjacent to the combustion chamber sidewall. 
     
     
         8 . The log stove of  claim 7  wherein the first ventilator port diameter is larger than the second ventilator port diameter. 
     
     
         9 . The log stove of  claim 1  wherein the ventilator port further comprises a gate. 
     
     
         10 . The log stove of  claim 9  wherein the gate is attached to the outside surface of the log billet. 
     
     
         11 . The log stove of  claim 9  wherein the gate is adjustable to adjust an opening size of the ventilator port. 
     
     
         12 . The log stove of  claim 9  wherein the gate comprises a combustible material. 
     
     
         13 . The log stove of  claim 10  wherein the gate further comprises a pin attaching the gate to the outside surface of the log billet. 
     
     
         14 . The log stove of  claim 13  wherein the pin comprises a combustible material. 
     
     
         15 . The log stove of  claim 1  wherein the slot has a first portion having a first constant width extending from the log billet top surface to a distance between the slot upper end and the slot lower end, and the slot has a second portion having a second constant width smaller than the first constant width, the second portion extending a remaining distance to the slot lower end. 
     
     
         16 . The log stove of  claim 1  wherein the slot is substantially perpendicular to the combustion chamber sidewall. 
     
     
         17 . The log stove of  claim 1  further comprising a second slot extending from the combustion chamber sidewall substantially opposite the first slot. 
     
     
         18 . The log stove of  claim 17  wherein the second slot extends substantially parallel to the first slot. 
     
     
         19 . The log stove of  claim 18  further comprising third and fourth slots. 
     
     
         20 . The log stove of  claim 19  wherein the third and fourth slots extend substantially perpendicular to the first slot.
