Abstract
Abstract An apparatus for loading unvulcanized tires on a tire vulcanizing machine of the sort which has a vertically movable loader arm with a contractibly expansible paddle at the fore end thereof, an oscillating cylinder cooperative with a movable arm for oscillating the loader arm in a horizontal plane, and a stand-by station for temporarily holding unvulcanized tires to be loaded on the vulcanizing machine, the loader arm being adapted to load the unvulcanized tires one after another in a mold on the machine by lifting, oscillating and paddle-expanding operations. The loading apparatus is characterized by the provision of a plural number of stand-by stations on a locus of oscillatory movement of one loader arm, and a plural number of oscillating cylinders cooperative with a corresponding number of movable arms for oscillating the loader arm between the center of the mold and a selected one of the stand-by stations.

Claim 3
Independent Claim
84 words
A method for loading an unvulcanized tire on a tire vulcanizing machine by holding said unvulcanized tire by a contractly expansible paddle, lifting and oscillating said unvulcanized tire over said machine and thereafter descending and placing said unvulcanized tire on a mold of said machine which comprises the steps of: placing and keeping unvulcanized tires at a plural number of stand-by stations located on a locus of oscillatory movement of said unvulcanized tire, and picking up a predetermined unvulcanized tire from said stand-by stations.
