Cup-adjusting Hub

“One end of the cup-adjusting hub, with inward bearings. The cones are formed of one piece with the spindles, and the adjusting cp C is screwed in the end of the hub shell, and locked in position by the screwed locking-ring R. The figure also illustrates a divided spindle for facilitating the removal of the tire for repair when required without disturbing the wheel, bearings, chain or gear-case. The chain side of the hub-spindle, not shown in the figure, is secured to the frame in the usual way; on the left side the spindle S projects very little beyond the adjusting cup. A distance washer W is placed between the end of the spindle S and the fork-end F. A detachable screw-pin, or the footstep, P, passes through the washer W, and is screwed into the end of the spindle S, the hexagod head of the detachable pin drawing all the parts securely together.” — The Encyclopedia Britannica, 1910
