Abstract

2995. Oldridge, S. T. Feb. G. No Patent granted (Sealing fee not paid). Signals, auto matic-alarm; signals, road-vehicles. -To detect the puncture of a pneumatic tyre of a motor-car, cycle, or other road vehicle, a tube D is threaded into the felloe F of the wheel, and a plunger C sliding through the tube is held in its inoperative position by the pressure of the tyre. On deflation, the plunger is pulled through the tube by a spring and releases an alarm. This alarm may consist of a clapper B striking against a globe A attached to the tube D ; or of a bell, attached to a hinged side of a box, Fig. 3, the side being locked when the tyre is inflated; or of a whistle or other wind instrument blown by the escaping air.
