CONVERTIBLE CAMP STOVE 



ADAPTATION TO LOCATION AND USE 



This type is primarily a camp stove, although 

 it may be used as a campfire. The simpler 

 units (pis. IV, V, and VIII) are appropriate for 

 the natural forest areas. There is, however, in 

 many campgrounds, especially in the larger 

 timber, a definite need for this convertible 

 unit which eliminates undue fire hazard, pro- 

 vides for cooking and for warming fire use, 

 and increases the convenience of everyday 

 use in a camp. 



These units ought to be so located that a 

 screen of natural grovrth will separate one 

 from the other. 



This camp stove, together vrith the stove 

 shown in plate XI-A, figure 4, are excellently 

 adapted to campground use. 



DESIGN AND CONSTRUCTION 



It should be constructed with an interesting 

 texture of informal stonework and should tie 

 naturally to the surrounding ground. 



In addition to the sand or gravel area which 

 naturally should surround any campfire or 

 camp-stove unit, there might well be a few 

 flagstones immediately in front of this camp 

 stove. 



The foundation walls should extend below 

 frost, in order to avoid the danger of uneven 

 settlement due to the excess of weight at the 

 chimney end of the camp stove. 



The chimney is lined with fire-clay brick and 

 the firebox is lined to the height of the side 

 walls. The firebox is entirely enclosed by the 

 solid top plate and the single door or double 

 doors across the front. 



The sohd top plate extends 2 inches over the 

 brickwork on either side and it is hinged at the 

 rear of the firebox as shown in figure 2. In 

 order to convert this stove into a campfire, the 

 doors are opened and the top is thrown back 

 against the chimney. A certain amount of heat 

 will continue to go up the chimney unless a 

 damper is installed to control the draft. 



The danger of warping is decreased by the 

 welding of two 1 by 1 inch angles across the 

 underside of the top plate (pi. XXII, fig. 4). 



The chimney approximates S'/? feet in height 

 above ground level. It may be Uned with lava 

 rock, or it may have a terra-cotta flue Uning in 

 place of the fire-clay brick. It is very desirable 

 that a spark arrester be inserted in the top of 

 the chimney, especially if the fire hazard is 

 very great. 



VARIATIONS IN DESIGN 



It is entirely practical to have the firebox with 

 the sides parallel (pi. XI A, fig. 4), rather than 

 to have the front of the firebox wider than the 

 rear, although the splayed sides reflect more 

 heat when used as a warming fire. 



If the front doors are omitted, then it will be 

 necessary to install a damper in the chimney 

 in order to properly control the draft. 



In figure 4, the height of the top plate above 

 the ground is approximately 16 inches. This top 

 plate may be lowered approximately 4 inches 

 by omitting the raised hearth and thus 

 leaving a total height of approximately 12 

 inches between the surface of the ground and 

 the top of the plate, with chimney lowered 

 proportionately.
