218 Improved Stove for Heating Rooms, &0. 



present position of its crown I, forms a reverberatory fur- 

 nace, or will make a sand-bath by reversing it. 



The space occupied by the fire-place in fig. 1, may ir) 

 this be converted into apartments for evaporating substances, 

 or occasionally for cooling tlieni by an opening at K to admit 

 cold air, while the warm air of the stove is excluded by a 

 register or door. The dotted lines show the manner in which 

 a second furnace may be connected by an opening into the 

 flue at L. 



In addition to the uses already pointed out, this stove 

 would probably be found extremely serviceable in drying 

 japanncrs' goods, and consuming the noxious fumes and 

 •gas which arise from the oil and varnish used in this bu- 

 siness. 



Since the stove is not limited to any certain dimensions, 

 it might be adapted to the drying of malt and hops, perhaps 

 of herbs, corn, and seeds generally. It nnght also be ac- 

 commodated to the purposes of the sugar-bakers, connected 

 with the great fires they employ for their boilers. It has 

 been shown to be useful in the confectioner's art, and pro- 

 bably it may be equally so in baking biscuits for the navy ; 

 nor less so in drying linen for the laundress, dyer, calico- 

 printer, and bleacher. I have myself found it well accom- 

 modated for a chemical elaboratory. 



The efficacy of the stove in ventilating, boiling, and steam- 

 ing, may easily be shown. In manufactories and rooms, 

 generallv, the heated and noxious part of the atmosphere 

 ascends towards the ceiling : if then the air-flue M, fig. 3,, 

 is continued upward according to the height of the room in 

 which it is placed, the air will be drawn from the top, and 

 the room become ventilated, while from the opening at N 

 it is siupplied, if requisite, with warm air. 



It IS unnecessary to show the various ways in which a 

 boiler may be connected with this plan : it is sufficient to 

 observe, that in the space allotted for the fire-place in fig. 1, 

 there is sufficient room within the body of the stove for this 

 purpose ; and that if the circulating air be made to pass over 

 the boiler, evaporation may be carried on very expeditiously 

 by the air removing the vapour as it arises. Finally, if an-
