Abstract: This invention discloses composite two faced picture, document and/or other artwork frames, each composed of two separate frames with panes permanently installed on elastomeric pads and fitted to allow pane to pane resilient contact with two sets of displayed material and mats clamped back to back between panes for alternate viewing of either side. Each pair of composite frames are opened and closed quickly and easily, by the user, for frequent changes of displayed material. A variety of methods of opening closing, hanging, or setting up for display, all designed for quick and easy operation, by the user without assistance or tools, are presented.

Abstract: An adjustable nose-rest mechanism for bi-focals that allows ready one-hand and variable adjustment of the nose rest elevation relative to the lenses in order to vertically position the lenses (rather than tilting of the head) for ease of viewing computer screens and the like. The mechanism generally includes a boss attached or hooked onto the bi-focals, said boss comprising a hollow sleeve aligned vertically. An elongate slider is slidably carried in the boss, and a nose rest is attached at the lower end of the slider. A set screw is threaded frontally into the boss and is tightenable against the slider. The slider can be adjusted along a continuous range of elevations and locked into any of said positions by tightening the set screw, thereby facilitating adjustment of the nose rest. A mechanism for temporarily attaching a singularly adjustable nose-rest to any standard bi-focals, comprising an internally threaded tube, adjusting yoke, and spring support member.
