The axle bearing consists of a bearing case and a collar formed integral with the bearing case as shown in this patent sketch. The axle bearing case is reamed out to form an opening to receive the adjusting cones provided with the surfaces for the axle bearing balls. The collar is fitted to receive the shank of the vehicle, and the collar is securely held in place by means of a set screw. By reference to the sketch it will be noticed that the bottom seat of the bearing case is movable on recount of being cut entirely through the bearing case and partially through at the other side from the opening in the collar. This construction admits of the bottom seat of the bearing case serving as a lock to prevent the unscrewing of the adjusting cones within the bearing case. This newspaper also shows the 1893 patent cutaway drawing of the bicycle axle bearing.

The newspaper claims that this bicycle axle patent was awarded in 1983.
