Balanced Houses 

 And Counter Balanced Ventilating Apparatus 



If you were on one end of a 

 board put across a barrel, and I 

 on the other, and you weighed 

 so much more than I that you 

 sent me up, while you went 

 down, it looks to me as if that 

 teeter-totter was out of balance. 



Now, if you should let my end 

 down again, and you move up 

 more towards the center, then a 

 complete balance could be estab- 

 lished, because the greater length 

 of the board on which I sat 

 would form so much greater 

 leverage, that it would offset 

 your additional weight when 

 nearing the banel. 



Id exacdy like fashion, you 

 might take the weight of iron 

 in one concern's house, and it 

 might be more than ours, but on 

 investigation you might find out 



Exactly the Mme teeter-tott«r principle ii applied to oar 

 counterbalanced ridse vcitilatlnfr apparatus. The weight 

 in the nprigbt, combined with the arrangement of the 

 cable drum and gear, creates a balance. The sash go up 

 practically as easily as the/ come doim. 



that it was out of balance in its 

 distribution. 



Or, to say it in another way: 

 HOW and WHEN you use the 

 iron has quite as much to do 

 with constructing a greenhouse, 

 as how much you use. 



Twin auto motors are perfectly 

 balanced, giving a continuous, 

 even distribution of power. 



Built as our houses are, you 

 have a perfecdy balanced frame 

 that evenly distributes all stresses 

 and strains. 



How would you like to make us 

 prove these statements? All 

 right, it's exacdy what we would 

 like to have the chance to do. 

 You say where and we'll be 

 there.
