Abstract: A weighing apparatus particularly for placing under a wheel of a vehicle for giving an indication of axle loading, said apparatus comprising a resilient body formed of an elastomeric material, such as rubber, a cavity being provided in the body and filled with liquid, the cavity being connected to an indicator by means of a conduit for indicating changes in volume of the cavity when the body suffers changes due to compression forces applied thereto by the member being weighed, the body has a resilient metal load plate bonded to the upper surface, a resilient metal load support plate mounted on the plate and a metal plate bonded to the body and spaced below the plate and to which reaction forces are applied during weighing, the plate is provided with a screw-threaded bore in communication with the cavity and a screw-threaded plug is in screw-threaded engagement with the bore, said plug having an inner end portion which engages with part of the wall of the cavity to prevent that part of the wall being deformed

Abstract: A weighing apparatus, particularly a portable apparatus for weighing vehicles, comprising a resilient body formed of an elastomeric material in which is formed a closed cavity containing a liquid, said cavity being connected by a conduit to an indicator for indicating changes in volume of the cavity when the body suffers changes due to compression forces applied thereto by the member being weighed, said body having a resilient metal plate fixed to an upper surface thereof, a resilient metal load support plate mounted on the plate and a further resilient metal plate embedded in the body and spaced below the plate and to which reaction forces are applied during weighing.
