Abstract: A pneumatically-controlled container ring handle applicator--a mechanical device for installing plastic handles around bottle necks by forcibly expanding a plastic ring of the handle as it is urged onto the bottle neck--includes a finger carrier to which carrier is connected a plurality of pivoting fingers that extend from the carrier through slots out of the tube to push a plastic handle ring down a frustum portion of the applicator, expanding the ring as it moves on the increasing frustum diameter until the ring falls off the end of the applicator over a bottle neck placed below the applicator. Movement of the carrier in the finger cylinder is pneumatically-controlled with a piston in a cylindrical tube that moves down a piston cylinder under pneumatic pressure and returns to a rest position under bias of a spring secured in the cylinder under the piston which is compressed as the piston moves down the cylinder. A piston rod connects the piston to the finger carrier.
