The above views will clearly show the great advantages possessed by 

 this Bearing from the combination of hardened steel balls and hardened 

 conical surfaces, with the facilities for universally adjusting the Bearing 

 in case of wear the frictional surfaces and points of contact are reduced 

 to the lowest possible minimum, thereby producing the most complete 

 Bicycle Bearing ever offered to the public.
