TO MAINTAIN AN EVEN TEMPERATURE 

 in your greenhouses, use a 



Foster Pressure 

 Regulator 



Qlass 



That's the class you want. Attach this simple device to the steam main just inside of your green- 

 house and obtain the exact temperature desired by turning the adjusting nut "K" (see illustration) to 

 the "right" for greater heat, to the "left" for less. At whatever pressure the valve is "set," the pressure 

 at all times will be absolutely constant. Sizes ^-inch to 2-inch have composition bodies; larger sizes, 

 to and including 10-inch, iron body, composition mounted. 



As an expert in your line, let us talk it over, as experts in ours. We recommend, we aid you in the 

 selection of the proper size, and should you require higher pressure than 15 lbs., the most suitable type 

 of our other styles of pressure Regulators would be recommended. 



"The Foster Pressure Regulators which have been installed in our greenhouses are 

 giving perfect satisfaction." Petek Reinberg, Chicago.

FLORISTS' REVIEW 



When Writing Advertisers 



Grates shown partly open, 

 resting on a. stand as used 

 in cast sectional boilers that 

 do not have grate supports. 

 Independent of boiler. Shak- 

 ing lever located just inside 



damper door. Adapted to large and small furnaces. Now 

 in use by greenhouse operators everywhere, and not one 

 complaint of grates getting clogged with cinders. For prices 

 give size of furnace. Try them in your residence furnaces.
