ABSTRACT:
A control rod (20) through a hollow axle (30) has a lever-operated cam (2) on one end which pushes a follower (8) against a first safety drop-out (50). On the opposite end of the control rod is an adjustment nut (15) surrounded by a safety interlock slide (11). When the cam is loose, a compression spring (19) urges the safety slide inward toward the second drop-out (50) where it is retained by a conventional safety tab or lip (51). The compression spring imparts enough tension on the control rod to pull the cam follower against the first drop-out, thus retaining the axle in the drop-outs despite a loose cam. To release the axle, first the cam is opened, then the slide is pulled outward with the fingers while the thumb pushes the adjustment nut inward, as with a hypodermic needle. Installation of the axle is the reverse of these steps, ending with closing the cam, with no need to readjust the nut. A conical compression spring (9) at each end of the axle centers the control rod laterally for easy insertion and removal of the axle in and out of the drop-outs.
