Abstract: 1,232,985. Air cushion vehicles; pneumatic spring wheels. BRITISH AIRCRAFT CORP. Ltd. 24 Oct., 1968 [25 July, 1967], No. 34077/67. Headings B7C and B7K. An air cushion vehicle has a skirt 2 depending from the body 1, the end parts 3 being pleated or segmented, and inflatable wheels 6 each mounted on an axle 7 perpendicular to the fore- and-aft axis of the body adjacent to lateral membranes forming the parts of the skirt 4 lying fore and aft, the lower parts of the wheels lying at or below the lower edge of the skirt. The wheels 6 which are made of a nylon fabric impregnated with rubber or neoprene are mounted in tandem closely adjacent the outer face of the respective membrane 4 on axles 7 which slope at an angle of 5 degrees so that the wheels 6 are cambered inwards towards the top. The wheels are closely adjacent each other though not touching when inflated and their contact with the skirt is lubricated by impregnating the fabric with a silicone finish and/or by a jet of high-pressure air. The wheels some of which may be driven to propel the vehicle each have inflatable inner and outer tubes 8 and 9 connected by membranes 10 with a reinforced centre 11 forming a hub 11a for an axle 7 and a reinforced outer tread 10a. The space adjacent to the hub 11a bounded by the reinforced centre portion 11 and the inner surfaces of the ring 8 may be inflated. Each wheel may comprise more than two concentric tubes.

An hydraulic tracer head comprises a stylus rod 42 universally pivotally mounted in an axially displaceable sleeve 70, two mutually perpendicular distributer valve assemblies X, Y being arranged in a horizontal plane and having pistons 22, 23 articulated to an extension 40 of the stylus rod, a third distributer valve assembly Z being located parallel to the stylus rod and between the assemblies XY. The piston 126 of valve assembly Z is operated by an arm attached to the sleeve 70. Lateral displacements of the stylus rod are adjustably limited through a first range by the setting of conical seatings embracing a ball 55, further displacements being resisted by springs 58 and finally arrested by a ring 52. Similarly axial displacements of the rod 42 and sleeve 70 are limited firstly by conical seatings embracing a ball 98 and then further displacement is resisted by spring 102. A rotary collar 80 attached to the sleeve 70 carries a plunger member 84 which can be placed either in an inoperative position or in a position in which it is biased by spring 92 against the stylus rod to give a constant inclination in a given direction to the rod. The distributer valve pistons may be connected (Fig. 5, not shown) to a ring surrounding the stylus rod by elongated flexible rods or even directly to the stylus rod. The distributer valve cylinders may have circular ports providing a flow path the rate of increase of area of which varies with progressive movements of the pistons. The tracer head is intended to be manually controlled in following a template.
