Abstract: The invention concerns a method and a device for attenuating oscillating movements and clamping in a predetermined position one end of a freely depending spoke for example when mounting spoke wheels. The free end of the spoke is permitted to slide into a slot which includes an energy attenuating structure which the spoke passes. When the free end of the spoke thereupon exits from the slot it is intercepted by a magnet and thereafter guided to a securing device by which it is clamped.

Abstract: A method and a device for automatically mounting spokes in wheels. In the method, the hub of a wheel and the rim of a wheel are interconnected by an inner layer of spokes being supplied in a first station, whereafter the procedure is repeated in a second station for mounting an outer layer of spokes. If desired, this can be done simultaneously with the mounting of an inner layer of spokes in a new wheel in the first station. The device for automatically mounting spokes in wheels comprises rim support means, hub securing means, means for feeding spokes into flange apertures in the hub, means for clamping the ends of the spokes for defining the positions thereof, and means for threading nipples onto the spokes.

Abstract: A crank bearing device for pedal vehicles comprises a cylindrical crank bearing shell, which is connected to the vehicle frame. A crank passes through this shell with a ball bearing bushing at each end of the crank arm. Between each of such a bushing and a cone, threaded onto the crank, are placed a number of ball bearings. The invention provides that these bushings have a cylindrical outer surface cooperating with a cylindrical inner surface of the shell and are provided with a number of low, protruding ribs. Through driving the bushing into the shell the ribs are forced into the material of the shell, thereby interconnecting the bushing and the shell with each other.
