The Florists^ Review 



March 22, 1917. 



This particular design of ball- 

 bearing vent hanger is bolted to 

 both the rafter and purlin, taking 

 the place of ihe regular purlin 

 knee. 



Here is our Standard Hall-bearing Hanger all apart. 

 It's built almost like a watch. But it has tne strength. 

 It stands the racket. 



This Ball=bearing Vent Hanger 

 Cuts Down Elbow Grease

|0R a long lime we have been using a ball bear- 

 it)g on some of our ventilating gears. And now 

 that we have equipped a shaft hanger w ith it, we 

 can't help wondering why it wasn't done ioug ago. 



Of course, it makes the apparatus run 

 easier— a lot easier. 



Yes, it does cost more than the old 

 hanger, but what of it? If it lakes a lot 

 of the lug and tug out of the ventilating, 

 what does the question of a little extra 

 on the cost amount to? 



But djn't for a minute cumpare this 

 ball-lieariiig hanger with tlmse that have 

 been rushed on the market in competi- 

 tion. 



Look at the photograph of the parts 

 shown above, and you will see how it is 



The old hanger. We 

 still make and sell a lot 

 of tlio!n. 



not skimped in any way. In fact, it's made just 

 like a bicycle bearing, or as any other dependable 

 ball bearing is made. 



Althougli there seems to be (|Uite a few parts, 

 its construction is simplicity itself. They 

 all go together easily and lit into a sur- 

 prisingly compact space. 



If you still prefer the old hangers at 

 •_'5c apiece, we have them. 



But once you have equipped a run of 

 ridge sash with the ball-bearing ones at 

 (iOc each, you will never go back to the 

 old ones. 



This ball-bearing hanger, in combina- 

 tion with our counterbalance gear, cuts 

 elbow grease down to almost no grease 

 atall.
