carried just under the ridge through 

 the whole, I should suggest the follow- 

 ing: Carry a 2%-inch flow from boiler 

 to partition between the second and 

 third; there use a reducing tee and con- 

 tinue the riser, using 2-inch to the par- 

 tition between the first and second, where 

 it can again be reduced from two to one 

 and one-half inches, also using a reduc- 

 ing tee. From each of these tees pipes 

 can be carried down the gable to supply 

 radiating pipes on the side walls or un- 

 der the side benches. In addition to 

 the 2 1^ -inch flow the third house will 

 require four 2-inch pipes under each side 

 bench. The second house should have 

 three 2-inch pipes under each side bench, 

 and the first house three 1 14 -inch pipes 

 under each side bench. It will be well 

 to have the top of the boiler lower than 

 the level of the pipes under the benches 

 by several inchfes, twelve to eighteen if 

 possible. The main return should be 

 planned in the same manner as the riser 

 and connected with boiler with as few 

 angles as possible. L. C. C. 



EXPANSION TANK TROUBLE. 



I am thinking of overhauling my heat- 

 ing system and want to hear a word of 

 advice. In two houses, I have on each 

 of the four walls three 4-inch cast- 

 iron return pipes, and the six pipes in 

 each house return to thoi boiler through 

 a 4-inch pipe twenty feet long. Now 

 I want to make the six 4-inch pipes in 

 each house return to the boiler through a 

 6-inch stone tile. Would this be advisa- 

 ble? I know something is wrong with 

 the returns, as when I get the water 

 heated up good the boiler pounds it out 

 through the expansion tank. H. A. D. 



While you do not state the point at 

 which your expansion tank is connected 

 with the heating system, I am of the 

 opinion that it is connected with the flow 

 pipes not far from the boiler, and that 

 it is not elevated far above the highest 

 point in the system. If this is the case 

 you can overcome your difficulty almost 

 entirely by connecting the expansion 

 tank with a %-inch pipe to the main 

 return, within fifteen or eighteen inches 

 of the point where it enters the boiler, 

 and elevating the expansion tank several 

 feet above the highest point in the 

 system, eight to ten feet. Make the ex- 

 pansion tank large, fifty gallons, and I 

 do not think you will find it necessary 

 to modify the size of the main return. 

 I do not think it advisable to attempt to 

 use a stone drain for the main return, 

 even if it were necessary to use 6-inch 

 pipe. " L. C. C. 



When you order that new boiler, omit the 

 common stationary grate bars and get the 



Martin Rocking Orate 



Repeat orders received from most of the 

 following leading growers show what they 

 think of it after trial : Peter Keinberg, Bas- 

 sett & Washburn. Emil Buettner, J. A. Bud- 

 long, Adam Zender, Sinner Bros., Wietor 

 Bros., Albert Dickinson Co., Poehlmann Bros. 

 Oo. and many others. 



Be sure to ask about the Rocking Grate 

 when you visit any of these growers. They 

 will teU you that they DO save coal. 

 Write for catalogue and prices.

of you last year. We would not have them out for double their cost and 



find them as sensitive as a watch. We will be In Chicago soon to take up
