Abstract: A steering tube clamp and stem assembly for a bicycle or other cycle in which the steering tube clamping parts are concealed inside a stem tube which extends away from the rider. The clamping assembly employs an axially extending cut and intersecting arcuate cuts in a wall of a sleeve which connects to the steering tube and a pair of spaced lugs which are integrally formed with the steering tube sleeve and extend in parallel into the stem tube. A clamping screw head is accessible through an aperture in the wall of the stem tube. The stem tube is welded to the steering tube sleeve and to two additional outside lugs which parallel the concealed lugs to minimize stresses in a welded connection of the stem tube to the sleeve.

Abstract: A changing device for shaft and hub connections, comprising a shaft end, a hub part surrounding the shaft end, and a conical clamping bushing disposed therebetween. There is also provided -means for retaining the clamping bushing on the end of the shaft in a way so that it cannot be lost, and at the same time serves to initiate biaxial displacement of the clamping bushing in relation to the end of the shaft. This permits assembling and dismantling of the hub part, whereby all other parts of the shaft and hub connection can remain mounted on the end of the shaft. This leads to particularly short tool changing times.

Abstract: A clamp having a U-shaped clamp body which engages a profile such as a rectangular pipe on three sides, while a fourth side of the profile is engaged by a bolt which is secured by a nut and extends through conical holes in the free legs of the clamp body. Conical washers on the bolt engage the conical holes on the far side from the pipe, meaning that the bolt is located eccentrically in the holes. Tightening the bolt the nut makes the clamp body squeeze the top side and the bottom side of the pipe. The conical washers in the conical holes make the bolt squeeze the pipe in the direction of the back side of the pipe. The pipe is thus squeezed from all sides.

Abstract: One end of a flexible cable of specified length attached to the end of a shaft and the other end attached to a light-weight and disengageable restraint anchor with a wedge-shaped cross section within a tube. The shaft cannot be removed from the tube, nor can cable be cut, because the anchor is located at a depth in tube greater than the specified length of cable. Anchor is comprised of an inner and an outer piece and operably attached to cable via the inner piece. Outer surface of outer piece essentially conforms to the tube inner diameter. During normal operation (random vibration and impact) the anchor is held in a specific location by a low-force radial force means comprised of a metal snap ring pressing outwards on outer piece. During an undesired removal, the inner piece and outer piece together provide a high-force radial constraint by means of wedge-shaped cross section such that any amount of tension on cable will be insufficient to move anchor from specified location.
