Abstract

11,494. Olsen, O. May 12. Pneumatic - tyre pressure gauges.- A gauge applicable to determining the pressure in pneumatic tyres, consists of a transparent tube A, containing a plunger 3, which is enclosed in an exterior shell 4 carrying graduations. When the tube A is applied to the tyre and the tyre valve is opened, the air passing into the lower portion of the tube A forces the plunger 3 upwards, so that its position relatively to the graduations shows the pressure. To effect a tight joint with the tyre valve, the tube A is provided with a washer 6 and an elastic sleeve 15. The exterior shell is formed with a perforated diaphragm 11 having a pin 12 which opens the tyre valve when the gauge is applied to the valve, To enable the position of the plunger to be adjusted, it is provided with convergent depressions at each end, within one of which rests a conical head 8 attached to a screw-threaded rod 9 which passes through the plunger and carries an adjustable conical nut 8<a> fitting the other depression. To facilitate the reading of the gauge in the dark, the plunger may be coated with a phosphorescent substance.
