Quaker City Ball Box Bearing

Having used Ball Box Bearings on our mills since 1890, we find the usual frictin has been reduced to a minimum and we are able to grind 20 per cent. more with same amount of power in a given time and also have the mill run cooler, than before we adopted the Ball Box Bearing. This device is a great improvement and is far superior to the best babbitt metal, phosphor-bronze or pure copper journal boxes usually found on machines of this nature. We can send these boxes by mail to fit any of our mills sold prior to 1890, and make this sug-
gestion for the benefit of users of Quaker City Mills who purchased same before we added this improvement. When ordering give letter and number of mill and diameter of spindle.
