CAETEE'S PORTABLE HOT- WATER APPARATUS. 



I HAVE herewltli sent a. rough sketch of n, 

 plant house whh my portable heating ap- 

 paratus tiierehi, showing the stove in part 

 gection. I have likewise sent a sketch of 

 the stove on a larger scale, with the 

 diameter of pipes and water space round 

 the fire and flue. The following descrip- 

 tion will, I think, suffice to enable the 

 reader to understand the construction : — 



A, iireplace closed in front with a re- 

 gulator to ash-pit door to regulate the 

 di-aught ; B, flue pipe passing through tlie 

 outer hase, c, and conducted out of the 

 Louse at any convenient part ; », water 

 space round the fire and flue pipe ; e, re- 

 turn pipe for circulating the water ; f, small 

 funnel or small cistern for supplying the 

 water. 



The general dimensions are as follows : 

 Fli*e-box, twelve inches by sixteen inches ; 

 outside pipe, six inches diameter ; inside flue 

 pipe, three inches diameter, which leaves 

 a space of one and a-half inch for water. 



The cost will vary according to size and 

 length of house, etc., the sketch represents 

 a twenty feet house, with apparatus eigh- 

 teen feet long. The cost of one the dimen- 

 sions given will be about £B, made of 

 strong galvanized iron. 



The advantages of this arrangement is 

 the portahility with the economy of fuel 

 and equal distribution of heat along the 

 front of the house. 



In large or extensive range of houses 

 the pipes can be carried in any direction, 

 as any other hot-water applications, and 

 two or more fireplaces can he attached with 

 the fireplace outside the building, or inside 

 with an air pipe from without to supply air 

 to the fire if found injurious by taking it 

 from the inside of the house. 



The best fuel is cinders or small coke or 

 common charcoal (not prepared). I think 

 if the latter was allowed to escape in the 

 house once once or twice a week, it would 

 he found to clear the house of flies and im- 

 prove the plants. 



My patent steam hoiler for agricultural 

 purposes has two fireplaces, one at each 

 end, with the flues passing twice through 

 the boiler and returning to the centre be- 

 fore it makes its exit. This arrangement 

 is not required for heating plant houses, but 

 is very effective for generating steam for 

 heating large establishments or drying 

 grain, etc. 



Should the readers of the I'louai, 

 World require fm-ther descriptions, I shall 

 be most happy to supply them.
