Tire-up-set′ting ma-chine′.
A machine for shrinking tires without cutting.
The tire is heated and then forcibly compressed endwise, so as to thicken it in one part and shorten it. It is then, while yet hot, placed on the wheel and shrunk in position.
Fig. 6484 is a machine for
upsetting, cutting, and punching tires.
The upper figure show the upsetter; the heater tire is placed between the clamps, one of which is on a sliding head; as the heads are brought together the tire is shortened.
The shears and punch are shown beneath, being operated by an oscillating cam, moved by rack, pinion, and lever.
