What is the Host Vital Point in Grate Construction? 



Grate makers and users 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-FRICTION ROCKING GRATE 



open longer under any conditions 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 Reinberg, Emil Buettner. Bassett & Washburn. Wietor Bros.. Adam 

 Zender, Siuner Bros., Albeit Dickinson Co., and many otliers.

Tuesday morning a 

 florist in Medina, Ohio, 

 ordered nine Emergency 

 Pipe Clamps, three each 

 1-in., 1^-in., l^fl-in.— 

 total cost $4.30. Just 

 contrast that with the 

 cost of renewing three 

 pipe lines! How much 

 can YOU save?

ference is not so great as it otherwise 

 ■would be. After connecting with the 

 expansion tank, run one or more 2^^- 

 inch flow pipes to the farther end of 

 the house. As a rule, in bouses twenty 

 feet wide and over, three pipes of this 

 size can be used to good advantage, arid 

 it is not advisable to attempt to supply 

 more than 300 square feet of radiation 

 with one 2%-inch flow pipe. One of the 

 flows may be under the ridge and the 

 others on the wall plates. Place a part 

 of the returns on the walls and the 

 others under the benches.
