STANDARD GRATE 

 FIREPLACE VARIATIONS 



ADAPTATION TO LOCATION AND USE 



This type of iireplace may be developed in a 

 number of ways as shown upon the accompany- 

 ing plate. Its simplicity of design, permanence 

 of grate, cheapness and ease of construction 

 are important factors which increase its pop- 

 ularity. It is constructed in one form or another 

 for use on picnic areas and on campgrounds, 

 from California to Maine and from northern 

 Washington to Florida. It is a comparatively 

 inconspicuous unit, and for use in its simpler 

 forms (as shown in pi. Ill, fig. 1; and pi. Ill A, 

 figs. 1, 2, and 3) in primitive areas and in high 

 mountain country near timber line, it has no 

 equal. As explained under plate III this unit 

 is not recommended for use in areas of high 

 fire hazard. 



The type shown in figure 6 is also not recom- 

 mended for use in areas where there is any 

 tendency toward vandalism or any rough 

 usage which might knock down the dry stone- 

 enclosing wall. The types shown in figures 7 

 and 8 are excellently adapted for areas 

 which are used at frequent intervals by rather 

 large groups who frequently have "fish fries." 

 These multiple units provide necessary in- 

 crease in cooking surface and have proven 

 to be very popular in actual use on a number 

 of recreation areas. In multiple units such as 

 shown in figure 8 the width of the top of the 

 enclosing wall on either side of the large fire- 

 place, may be narrow (approximating 6 

 inches) because of the reduced requirements 



for any "warming shelf", and because stones 

 of the width normally used on either side of 

 the single unit fireplace might cause incon- 

 venience in the actual use of the fireplace. 



Wherever the single units are used for camp- 

 ground cooking, it is generally desirable that 

 a removable plate be used to cover a portion 

 of the top of the grate as shown in figures 1 

 and 5. 



DESIGN AND CONSTRUCTION 



In addition to the comments with reference to 

 the design and construction of this type of 

 fireplace included under plates II and III, 

 this further information may be of value. 



This fireplace is sometimes designed as 

 shown in figures 4 and 6 with the long side 

 open to the front. When the fireplace is thus 

 designed it is desirable that the top of the sur- 

 rounding wall be slightly above the top of the 

 grate and yet not exceeding 18 inches in the 

 height inasmuch as a wall of greater height 

 would not be convenient for use as a seat on 

 which to sit while cooking food on the grate. 



The efficiency of this fireplace is greatly 

 increased by the use of the removable top plate. 



Whenever a fire-clay brick lining is used in 

 the firebox it is very desirable that the stone 

 masonry construction protect and cover the 

 ends of the fireplace lining as shown on the 

 right-hand side of the fireplace in figure 5. 

 The method of anchoring the standard grate is 

 shown in plate III.
