A rough sketch of the old one, by way of comparison.

New Automatic Valve For Your 



Overhead Mains 



IT'S a great improvement over that big barrel 

 shaped one we used to make. 

 It's less than half the size. 

 Simpler in construction. 

 Easy to connect up. 

 Easy to clean. 



Just tap in a connection at the highest point of 

 your mains, screw on this Little Marvel Valve and 

 forget it. 



Day and night it's there, automatically worliing. 

 freeing the mains from all air pressure, and in- 

 creasing your lieating system's efficiency. 



Considering how carefully it's made; the accuracy 

 with which it works; and the added efficiency it 

 gives your heating; the price we ask for it is ridicu- 

 lously low. 



Send for price.
