Claim 1
Independent Claim
314 words
A transfer and storage system for shipping containers comprising the combination of a horizontal array of open-ended compartments provided with container support means and openings leading into the compartments, a container handling crane provided with a cage mounted for horizontal and vertical movement adjacent to and for alignment with said compartment openings, said compartments each being provided with horizontal rail means disposed in spaced relation to and above the compartment container support means, substantially horizontal rail means carried by the crane cage and selectively alignable with the rail means of the various compartments upon predetermined movements of the cage relative to the compartments, a carriage mounted for travel on the rail means of the cage between a retracted position within the cage and an extended position within a given compartment, a transfer frame means associated with and drivingly connected to the carriage for moving the carriage between said retracted and extended positions, downwardly projecting container lift means on the carriage for releasably engaging a container and for gripping the container as the carriage and container are moved between said retracted and extended positions, means for adjusting the lift means to the size of container to be handled, said lift means also being adapted to raise and lower a container with respect to the carriage in order to lower a container from the carriage onto a compartment container support means or to lift a container from the compartment container support means into a carrying position on the carriage and drive means on the cage and connected to the transfer frame means for imparting movement to the frame means and coupling means connecting the transfer frame means and the carriage for telescoping the carriage relative to the frame means and the cage and moving the carriage into and out of a given compartment when the rail means of the compartment and the cage have been aligned.

Claim 3
Dependent Claim
28 words
A system as set forth in claim 1 wherein the containers are provided with upwardly disposed pickUp means engageable with the downwardly projecting lift means on the carriage.
Claim 4
Dependent Claim
21 words
A system as set forth in claim 1 wherein the means for adjusting the lift means are mounted on the carriage.
