Abstract: A seat support mechanism for a tilting chair with separate adjustments for front and rear tilt, which mechanism includes interconnected torsion bars which are adjustable to vary the resilient restraining force which opposes rearward tilt of the seat when occupied. The support mechanism also includes a separate torsion member and adjustment to vary the resilient restraining force opposing front tilt of the seat when the seat occupant leans forward.

Abstract: A concealable lighting fixture wherein the longer, vertically extending leg of a support frame is mounted in a vertically extending bearing in a bracket so that the frame is vertically shiftable in and rotatable with respect to the bracket. A diametrically extending support pin is mounted in the lower end of the longer leg for engaging a support surface on the upper end of the bracket. When engaged with the support surface, the support pin releasably retains the frame, and a lamp assembly on the upper end of the support frame, in an elevated operative position. In one embodiment, the bearing for the longer leg of the frame is provided by concave recesses in the inner faces of a pair of vertically extending flanges on one side of the plate portion of the bracket. In another embodiment, the bearing is provided by a tube welded to the plate portion.
