Abstract: A self adjusting elevator, especially for use in a storage cabinet, or the like, which has a recess in which the elevator is horizontally disposed and within which the elevator is vertically moveable in conformity with the weight carried thereby. The elevator according to the present invention has a spring device incorporated therein which maintains tension on cables which support the elevator. As the elevator is unloaded, by removing articles therefrom, the elevator rises in the recess of the storage compartment thereby maintaining the articles thereon within easy reach. The elevator according to the present invention is particularly characterized in an improved arrangement for adjusting the spring device carried by the elevator thereby to modify the tension exerted on the aforementioned cables by the spring device.
