A Prominent Rose Grower Said to Us 



the Other Day: 



Note machine operates 

 on worm and gear 

 principle. All gears are 

 entirely enclosed so that 

 no water or dirt can get 

 onto them. 



"You have the finest Venti- 

 lating Apparatus I have 



ever seen. 



)> 



This is the shaft hanger. 

 There are 9 white metal ro lers 

 all operating loosely in their 

 case. No pins to bind or break. 



This man has a lifetime experi- 

 ence in greenhouses and has 

 used every known make of 

 ventilating apparatus. He 

 knows what he is talking about. 



Steel lifting arm working on the rack and pinion prin- 

 ciple. The very least amount of leverage and smoothest 

 operating. 



w 



Our elbow arm is made entirely of steel. No castings to 

 break.
