Patent number: 6626501Abstract: A bicycle may have a combination comprising a wheel and a rim with a hole in the rim, an inner tube with a valve stem in the hole in the rim, and a tire. If the air pressure is low in the inner tube and the bicycle is ridden with the wheel rotating, the valve stem and the wheel may move with respect to each other. The valve stem is in the opening in the rim. With the low air pressure in the inner tube, the inner tube may slip or move with respect to the rim. The slippage or moving places a stress on the valve stem with the possibility of damaging the inner tube and valve stem and causing the air leak as the valve stem is not definitely positioned. The subject invention is a decorative stabilizing device for definitely positioning the valve stem with respect to the rim and lessening the possibility of causing an air leak in the bicycle inner tube.Type: GrantFiled: January 17, 2001Date of Patent: September 30, 2003Inventor: Paul Davidoski

Patent number: 4487241Abstract: A system is disclosed for warning that the pressure in one tire of a pair of dual tires is more than a predetermined amount below the pressure in the other. The system comprises a device fitted to the valve stem of the outer tire and having a single air inlet and two air outlets connected one to each tire. Two pistons are subjected to tire pressures and themselves act on a lever. When the tire pressures differ, the forces on the lever are unbalanced, and the lever tilts. A trigger unit is mounted on the rim of the inner tire and linked to the lever by a stiff wire. When the wire is displaced, a spring loaded arm of the trigger unit is released. On the body of the vehicle there is a switch the operating member of which is struck by the spring loaded arm after that arm has been released. The switch is connected to a warning device in the vehicle cab.Type: GrantFiled: September 20, 1982Date of Patent: December 11, 1984Inventor: Izak F. van der Merwe
