With Our Self-feeding Hot Water Boilers 



Springfield, Mo., May 15, 1906. 

 Gentlemen :— Youre of the 11th at hand. The Wilks heater bought 

 from you last fall has done finely. We burned coke and it haa done jnat 

 fine. By filling up the magazine about 9 or 10 o'clock and cloaing it up 

 all around, we found a good fire in it by 7 a. m. The grate is one of the 

 best arrangements we ever saw for an ordinary sized plant. It is one of 

 the best heaters I have ever seen. Yours truly,

ters with a coil of 1^-inch pipes and 

 under each bed (eight of them) with a 

 1-ineh pipe. How many pipes will be 

 needed? There is no partition between 

 the two houses. How many 1^4 -inch 

 pipes will be needed under the two 8-foot 

 gutters and the one .'5-foot gutter? 



A. V. B. 



Put in twelve lV4-inch pipes in each 

 house, with eight on each outside wall. 

 Put two under the gutters to melt the 

 snow. Your idea about the main and 

 general heating system is all right.

FROM HOT VATER TO STEAM. 



I am changing from hot water to 

 steam, and should be pleased to know, 

 through the Review, if the details of my 

 plan are correct. The potting shed is at 

 the northwest corner of the grounds and 

 the boiler-house is near the opposite cor- 



What is the Most Vital Point 

 in Grate Construction? 



Grate makers and nsers agree 

 that the most important point 

 is to keep the air spaces open 

 as long as possible under all 

 conditions. 



We guarantee to keep the 

 air spaces of the 



Martin Anti-rriction 

 Rocking Grate 



open longer under any condi- 

 tions than can be done by any 

 other grate in existence. 

 The hottest fire you can build will not warp a "Martin," and it can be 

 installed without disturbing the brick work. 



We refer to Peter Eeinberg, Emil Buettner, Bassett & Washburn, Wietor 

 Bros.,- Adam Zender, Sinner Bros., Albert Dickinson Co., and many others.

ner. House No. 1, which is 22x100, ex- 

 tends in a southeasterly direction from 

 the potting shed. The flow pipe in this 

 house would be overhead and the returns 

 would consist of one 2-inch pipe on the 

 walls or under the gutter and six 1%- 

 inch pipes under the benches. Would 

 that be enough to carry a temperature of 

 56 to 58 degrees in zero weather, in this 

 Pennsylvania climate? House No. 2, 

 which is also 22x100, runs straight east 

 and west, with its west end joined to the 

 potting shed and the north end of house 

 No. 1. In this second house there would 

 also be an overhead flow, with one 2-inch 

 return on the north wall and nine IV^- 

 inch returns under the benches, to main-
