A Contrivance for conveying Steam from Boilers. 2G5 



is the case at my works, being mj first essay ; but this is 

 not immediately necessary, for in the bleach house belong- 

 ing to Messrs. Benvon, Benyon, and Baze, flax-spinners, 

 of this place, I advised the steam to enter the smoke flue, 

 about SIX teet above the top of the pan, and with the same 

 good eflfect. 



Several of my friends here have adopted them in their 

 kitchens, and wash and brew- houses. The steam flues are 

 variously curved, as the situations required them to reach 

 the nearest or most convenient smoke chimney, and with 

 the same uniformly good success. I would, however, re- 

 commend, that at the lower part of the aperture, where the 

 steam enters a smoke flue, a stone may l)e made to project 

 a little way into the chimney, in order to break the current 

 of the ascending smoke, and thereby facilitate the entrance 

 of the steam. 



I would remark further, that in some cases a curved or 

 angular form may possibly be found the most eligible for 

 the steam chimney, in order to prevent a gust of wind, or 

 any other casualty, from forcing soot down into the liquid 

 in the pan. — I have not yet witnessed any immediate neces- 

 sity for it myself, and therefore merely suggest it as possi- 

 ble, but yet very easily remedied. 

 I am, sir,

AA, the brickwork surrounding the pan. 



B, the steam chimney, made of wood, about two feet 

 broad and six inches deep. A small opening at the back 

 part ot the pan admits the steam into this chimney, it may 

 from ihence be carried up to the top of the building or 

 turned into any smoke chimney near at hand. 



In order to keep the w^ter in the pan as hot as possible 

 during the night, ihere are two dampers in the steam chim- 

 ney at D, and if both these dampers are shut, and the whole 

 top of the pan covered closely over at c, the boili;ig water 

 even when the fire is withdrawn, will keep liot for the 

 workmen till the next morning.
