Abstract: A self-retracting hydraulic jack assembly is provided which includes a leg retraction compression spring carried by the piston rod assembly encased within the hydraulic extension cylinder of the jack. The hydraulic jack has first and second telescoping tubular leg members that are extensible relative to one another in response to the introduction of hydraulic fluid through the piston rod assembly and into the extension cylinder of the jack assembly. A third freely adjustable drop-leg telescopes into the other legs of the jack assembly through a cam actuated pull-pin casting mounted thereto.

Abstract: A finger ring is provided which includes a size-accommodating inner liner formed of a pliable, flexible and resilient material throughout and adhered to the inner diametrical surface of the ring. The liner includes a plurality of peripherally spaced flexible ribs extending inwardly therefrom to help facilitate ease of placement and removal of the ring from a person's finger, and to facilitate adjustment to and/or accommodation of variances in ring sizes. The outer substrate of the ring is formed with a liner retention shoulder to help retain the liner and resist shearing forces subjected thereto upon transition of the ring on and off the finger. The ring may be configured to permit simultaneous formation of aesthetically pleasing designs on the outer surface of the ring during the overmolding process utilized to form the inner liner therefor.
