You have noticed that tlie 

 hand wheel standard on 

 this one is much smaller 

 than the other. That's be- 

 cause it is intended for 

 short runs to 50 feet, 

 which requires smaller

 ber 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 teet- 

 ered, I could do it "easy as 

 pie." His weight was then 

 counterbalanced 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 teeter board. The coun- 

 terbalanced weights, "me."

goes down. No, 



that's wrong. 



It goes up just 

 a little harder than it goes 

 down, so that when the lever 

 lock is released, the sash will 

 close down themselves.
