STOVE-WARMING COMBINATION 



ADAPTATION TO LOCATION AND USE 



This fireplace approaches the camp stove type 

 and is excellently adapted to campground use. 

 These larger types are not recommended for 

 the open and extensive picnic areas requiring 

 a number of cooking units. The ideal location 

 for such fireplaces is one where the ground 

 level may be raised at the sides and the back 

 to reduce apparent height. 



The low chimney in which a spark arrester 

 may be inserted, if necessary, is added protec- 

 tion against any fire hazard, especially in the 

 timber areas of the West. 



The use of this unit as a cooking stove, or as 

 a warming fire, is easily accomplished by rais- 

 ing the hinged plate and the grill as shown in 

 figure 4. 



DESIGN AND CONSTRUCTION 



The design includes provision for a grill or 

 grate and or a solid plate, both of which are 

 hinged on bar hinges as shown in plate XXI, 

 figure 4. When the top grate and plate are 

 thrown back against the chimney, this unit is 

 converted into a warming fireplace. For use in 

 cooking, either the grill or the plate may be 

 used. 



Where fuel economy is an important factor, 

 the shelf shown in figures 4 and 5 may be 

 lengthened as indicated by the dotted lines, 

 thus reducing the depth of the firebox proper 



while retaining the same area of cooking 

 surface. 



The stone platforms on which to place cook- 

 ing utensils may be constructed as shown in 

 the sketch. 



The foundation for this type of fireplace 

 should be carried below the frost line and the 

 fire-clay brick hearth should be supported on 

 a reenforced concrete slab, as shown on this 

 drawing. The firebox is lined with fire-clay 

 brick laid as stretchers. The top plate ought 

 to be 10-gage sheet iron. It is not necessary to 

 reenforce this plate because the plate will rest 

 directly on top of the grate. 



The stonework must be laid in an informal 

 manner with carefully selected native stove. 



The low chimney is lined with fire-clay brick, 

 laid flatwise. An arch constructed of fire-clay 

 brick extends across the flue opening. The top 

 of this arched opening is slightly below the level 

 of the plate. 



VARIATIONS IN DESIGN 



Where steelwork is available at no abnor- 

 mal cost, two 3- by 3-inch angles with '74- by 9- 

 inch plate riveted to the under side may replace 

 the arch and will improve the appearance. 



The raised hearth may be omitted if the lower 

 elevation of the top is acceptable and the height 

 of the entire mass will thus be reduced approxi- 

 mately 8 inches.
