[Classes 144 (i) and 144 (ii).] Pneumatic tyres of the kind adapted to be mounted directly on a hub barrel, and particularly for use on the landing-wheels of aircraft, are built up from one or more plies 28 of rubbered cord material, the edges of the flat band thus produced being contracted by means of rings 34, and the structure then shaped to tyre form on a spherical air-bag. Other reinforcing bead-cores, such as 39, may be fitted on either side of the rings 34. The latter may have interlocking ends which may also be pinned together. The tyre is clamped between flanged collars 52 keyed on the hub-barrel 53 and secured by nuts 56, 57. The tyre beads and the flanges 54 of the collars 52 are formed with interengaging ribs 48, 49 respectively. Specification 336,715, [Class 144 (ii), Wheel tyres, Pneumatic &c.], is referred to. |
