Abstract
This disclosure relates to apparatus for vulcanizing a tire, and includes a pair of generally annular split dies which are axially movable relative to each other, and a pair of generally circular supports surrounded by the dies. The supports include bead seats which are engagable with the axially outer sides of the tire beads so as to form a closed space between the supports and within the tire. The space is supplied with a pressure medium which is heated during vulcanization. The supports are axially movable relative to each other and to the dies. Each of the supports has mounted thereon a plurality of pivotal members which are movable into engagement with the axially inner sides of the tire beads. The pivotal members press the beads tightly against the bead seats in order to form a seal between the beads and the bead seats.

Apparatus for vulcanizing a tire, comprising a pair of generally annular split dies axially movable relative to each other, a pair of generally circular supports surrounded by said dies, said supports including bead seats adapted to engage the axially outer sides of the tire beads so as to form a closed space between said supports and within the tire, said space being adapted to be supplied with a pressure medium and heated, said supports being axially movable relative to each other and to said dies, a plurality of members pivotally mounted on each of said supports adjacent said bead seats, each of said pivotable members including a plate movably mounted adjacent the free end thereof, and compression spring means for urging said plate against the associated tire bead annular tension spring means mounted on said pivotable members of each of said supports for urging said pivotable members to pivot into a retracted position away from the tire bead, and drive means provided on said supports for urging said pivotable members into compressive engagement with the axially inner sides of said tire beads on said bead seats.
Apparatus for vulcanizing a tire, comprising a pair of generally annular split dies axially movable relative to each other, a pair of generally circular removable supports spaced radially inwardly of said dies, said supports including bead seats adapted to engage the axially outer sides of the tire beads so as to form a closed space between said supports and within the tire, said space being adapted to be supplied with a pressure medium and heated, at least one member movably mounted on each of said supports adjacent said bead seats and movable into engagement with the axially inner sides of said tire beads, and drive means mounted on each of said supports and connected to said members associated therewith for moving said members.
