BALL-BEARING HINGES.

They Render the Door’s Motions Positively Squeakless. A ball-bearing door hinge? Why not? No squeaking of the door, no working up of the pin, no greasy butt

coated with dust and lint, no wearing down of the butt and rubbing on the threshold, no crowding and pushing to open the door; compact, simple, and cheap. Surely it is a very appropriate use for ball bearings. The

engravings show the whole thing In a nutshell. Ais a steel plate washer, B the guide, C the cover, and D is the whole hearing washer placed between the two parts of the butt.
