28 DESCRIPTION OF A STOVE. 



fary, by burning there a few flips of paper, or other light corn- 

 bull ible, I fay if necejfary, becaufe I have found by experi- 

 ence, that this precaution may be neglecled, as foon as the 

 ftove has been heated fo as to have loll all its internal damp- 

 ncfs. 



The door of this fort of blower, or air-vent, ought to fhut 

 very clofe. For this purpofe it is fufficient, to cut a piece of 

 brick of the proper lizc, to make a hole in it to receive a han- 

 dle, and to fatten upon it a piece of plate iron projecting a 

 little all round it. 



Fig. 5. Plan at the height of the line E F, fig. 1. 



Fig. 6. Tranfverfe feclion at the line G H of fig. 3, which 

 (hews the height of the fire-place, and the firft direclion of the 

 flame. 



V points out the arrangement of the heat pipes. 



The dotted lines give the profile of. the party walls, which 

 form the four grand circulating pipes. 



R the pipe which conveys the fmokefrom the circulatory pipes 

 into the chimney, and in which is the regifter that cuts off 

 the communication. It is a common ftove tunnel of plate iron ; 

 but it would be better to ufe a fubftance more flowly conduct- 

 ing heat, as an earthen tube made on purpofe, for that part in 

 which the Aider or flop plate acls. 



The elbow made by this pipe to reach the chimney renders 

 it upnecefTary to repeat, that it is a point of the full import- 

 ance for the body of the ftove to be completely feparate from 

 the wall. That which I have defcribed is 25 centimetres 

 (about 9 inches) diftant from the nearer! point of the nich in 

 which it is placed. 



S is an elongation of the perpendicular pipe that enters into 

 the chimney. It is intended to receive the water that might 

 condenfe in the upper part, to prevent it from getting into the 

 /love. The cap at the end of this elongation allows the pipe 

 to be cleaned without taking it down. 



The dotted lines forming the fquare fpace Q mark a place 

 where a nich may be made, or a fort of little ftove, as is don© 

 in fome of the Swedifh ftoves, and would advantageoufly fup. 

 ply the place of the brick-work, with which it mull otherwife 

 be filled up. 



All thefe figures being drawn on the fame fcale, there will 

 be no difficulty in preferving the proportions of the parts.
