Archival history
MERL 'Catalogue index' card – ‘… // DATE ACQUIRED: // GROUP: // NEGATIVE: // PERIOD: // PLACE OF ORIGIN: // NUMBER: // DESCRIPTION: …‘ The trying ring is a fixture at ground level in the wheelwright's yard. When the wheel is ready for tyring, it is fixed down on this ring by the Hub clamp. One end of which is exbedded in the centre of the ring. The wheel once it is fixed on the clamp is made rigid by screwing down the handle at the top of the clamp. Near the tyring ring a fire of straw and wood is lit, and the tyre is expanded by heat on it. The tyre is seized by tongs and hurried to the clamped wheel, and is beaten over the rim. As it slips over the felloes, cold water is thrown over it, and as it contracts the wheel is firmly gripped by the iron tyre. //, MERL miscellaneous note - 'The hup clamp consists of a round shaft, the top of which has a screw thread, a square piece at the other end is used for fixing onto the ring, a piece of iron horizontal to the shaft screws down the thread to clamp the wheel and 2 wooden pieces, one square shaped which is 3 ins above ground level when the wheel is tyred.'
