Abstract
474,308. Preventing unauthorized use of bicycles. NIELSEN, N. C. July 22, 1936, No. 20254. [Class 79 (iii)] To prevent unauthorized use, the hub 16 of a bicycle wheel is locked against rotation by key controlled means provided in a housing 1, 20 secured to the end of the fixed axle or to the cycle frame. In the form shown in Fig. 2, a ring 3 mounted on a pivot pin 2 in the housing is pressed by a spring 18 tending to cause a lug 4 on the ring to pass through an opening in the inner wall of the housing to engage one of a number of openings or recesses 5 in the hub. The ring is normally held out of action by the retention of a pin 8 thereon between a pivoted arm 9 and a number of spring pressed pivoted wards 10 adapted to be controlled by a key inserted into a barrel 13 co-operating with slots 21 in the housing. The locking device is put in action by pressing an external arm 12 fixed to the pivot 19 carrying the arm 9, the arm 9 being thereby depressed allowing the pin 8 and with it the ring 3 to swing under the influence of the spring 18. The key wards are at the same time moved up by springs 23 and prevent return of the pin 8. Release is effected when the key whilst depressing the wards, engages a notch 6 in the ring and returns the ring to the position shown in Fig. 2. In a modification, Fig. 5, the housing contains a pair of pivoted brake-like arms 29 with corrugated inner surfaces and pressed by springs 18 into engagement with the corrugated bed of a groove in a collar 26 threaded on the end of the axle and secured by an oppositely threaded nut, the arms 29 being releasable by a key actuated cam 34.
