Title: Improvements in or relating to apparatus for signalling fall of pressure in vehicle tyres
IPC: B60C23/02
Filed: 1950-02-17
Abstract: 689,633. Pneumatic tyres. CONTRI, G. D'O. Feb. 17, 1950 [Feb. 24, 1949], No. 4153/50. Classes 144 (i) and 144 (ii). A device of the kind described in Specification 499,911 for automatically controlling, and signalling fall of, pressure in twin pneumatic tyres, comprises a wheel-housing connected to a compressed air supply and fitted with a flexible diaphragm which forms a closure for a space in the housing having independent connections to the tyres. The deformations of the diaphragm, through fluctuations of tyre-pressure, are resisted by a spring-controlled valve subject to dial-controlled compression-adjustment and are utilized to actuate the signalling devices. As shown, the housing 1 has a wall 5 separating a sealed chamber 2 from the chamber 3 and formed with ducts leading to the tyres. The flexible diaphragm 7 in chamber 3 is clamped to the wall 5 by a collar 8 and is fitted over the hollow stem 9<SP>1</SP> of a headed member 9. An angled duct 10 in the head of member 9 connects a space 4 in the wall 5 with the controldevice and is normally closed by means of a spring-loaded valve 13. Excess tyre-pressure moves the valve 13 to open the space 4 to atmosphere until the pressure is reduced to conform with the imposed load on the valve which is predetermined by adjustment of a cap 18 fitted with a hand-grip. Coaxial with the member 9 is a hole in the wall 5 closed by a rubber cap 21, the flange of which is clamped against the wall 5 by a collar 22 having an arm 24 with a forked, bowed outer end. A rod 23 passing through the collar 22 bears at one end against the bottom of the cap 21, and at its other end against the shorter arm of a rocker 27 which is pivoted between the arms of the fork. The rod 23 is held up to the cap 21 by means of a curved spring terminal 28 bearing against the wall 5 and the longer arm of the rocker 27. On fall of pressure in the space 4, due to tyre-failure, the rod 23 is moved to actuate the rocker 27 whereby the terminal 28 is moved into contact with a fixed terminal 29 in the signalling-circuit. A pressure-gauge is fitted in the chamber 2.
