HORTICULTUEE 



March 3, 1917 



WELL do I remember when a kid, playing 

 teeter totter, how hard it was to bear down 

 my end of the board when Fatty Jones was 

 on the other end. But when he slid up nearer 

 the log on which the board teetered, I could do 

 it "easy as pie." His weight was then counter- 

 balanced or evened up by mine. 



Exactly the same principle is put into operation 

 by our new counterbalanced gear. 



The sash might well be "Fatty Jones." The gears; 

 the teeterboard. The counterbalanced weights, 

 "me." 



When rightly installed and counterbalanced this 

 gear runs the sash up, as easy as it goes down. 

 No that's wrong. It goes up just a little harder 

 than it goes down; so that when the lower lock 

 is released, the sash will close down themselves. 

 Close down — but not slam down. 

 It will come down itself to within a few inches of 

 the header and then a half tuni of the hand wheel 

 pulls the sash down snug and tight. 

 It is made for short runs, with rod and arm. And 

 for long runs where the rack and pinion is used. 

 The counterbalanced gear is now part of the stand- 

 ard greenhouse equipment.
