Tire loader

A tire loader comprising a movable frame, a horizontal plate mounted for rotation on a vertical axis, loader shoes mounted on said frame for radial movement to and from said axis, respective link means interconnecting said plate and each shoe, each link means extending at a common angle with respect to a radius whereby rotation of said plate in one direction will reduce said angle thus moving said shoes radially outwardly and rotation of said plate in the opposite direction will increase said angle thus moving said shoes radially inwardly, said plate being journaled on a vertically extending non-rotatable pin, radially extending slide bars secured to the bottom of said pin, one for each loader shoe, and means mounting each loader shoe for sliding movement on its respective slide bar, each loader shoe being supported on its respective slide bar by horizontally spaced pairs of slide blocks of elastomeric material, each block being in sliding frictional engagement with the slide bar, each loader shoe including two parallel ears, and fasteners interconnecting said ears, each fastener extending through a sleeve spacing said ears.

A tire loader comprising a movable frame, a horizontal plate mounted for rotation on a vertical axis, loader shoes mounted on said frame for radial movement to and from said axis, respective link means interconnecting said plate and each shoe, each link means extending at a common angle with respect to a radius whereby rotation of said plate in one direction will reduce said angle thus moving said shoes radially outwardly and rotation of said plate in the opposite direction will increase said angle thus moving said shoes radially inwardly, said plate being journaled on a vertically extending non-rotatable pin, radially extending slide bars secured to the bottom of said pin, one for each loader shoe, means mounting each loader shoe for sliding movement on its respective slide bar, said plate including a hub journaled on said pin and an arm projecting from said hub, said arm being pivotally connected to the rod of a piston-cylinder assembly, a second arm projecting from said hub, a stop rod pivotally connected to said second arm, a fixed stop block through which said stop rod slidably moves, and adjustable stops on said stop rod on opposite sides of said stop block operative to limit rotation of said plate in said one and opposite directions.

A tire loader comprising a movable frame, a horizontal plate mounted for rotation on a vertical axis, loader shoes mounted on said frame for radial movement to and from said axis and respective link means interconnecting said plate and each shoe, each link means extending at a common angle with respect to a radius whereby rotation of said plate in one direction will reduce said angle thus moving said shoes radially outwardly and rotation of said plate in the opposite direction will increase said angle thus moving said shoes radially inwardly, a piston-cylinder assembly operative to rotate said plate in said one and opposite directions, said piston-cylinder assembly being pivotally connected at one end to said movable frame, and an adjustable stop limiting the rotation of said plate in said one direction and thus the movement of said shoes radially outwardly.

A tire loader comprising a movable frame, a horizontal plate mounted for rotation on a vertical axis, loader shoes mounted on said frame for radial movement to and from a common center, and respective link means interconnecting said plate and each shoe, each link means extending at a common angle with respect to a radius whereby rotation of said plate in one direction will reduce said angle thus moving said shoes radially outwardly and rotation of said plate in the opposite direction will increase said angle thus moving said shoes radially inwardly, said link means including adjustable length connecting rods hingedly connected to said plate and the respective shoes, said connecting rods being independently and substantially continuously adjustable in length through a selected range.

A tire loader comprising a vertically and horizontally movable support, a frame secured to said support, a set of loader shoes mounted on said frame for radial movement to and from a common center axis, a rotatable plate, and adjustable length link means interconnecting each shoe and said plate whereby rotation of said plate about a vertical axis will move said shoes radially, said link means being independently and substantially continuously adjustable in length through a selected range.
