<p>ADJUSTABLE WEAVER'S BENCH An adjustable wooden bench has four legs, the upper portions of which are connected by a pair of horizontal rails provided with vertical openings through which the legs extend. The rails support a seat that is slidable lengthwise of them. A horizontal footrest rail like the top rails is mounted on the lower portions of the front legs. The top front rail is supported by a pair of flexible cables anchored at one end to the front legs above the rail, with the cable extending down through the rail and then lengthwise of the rail in opposite directions in engagement with its bottom and then down to anchors on the other front legs. Normally, the cables are locked against movement lengthwise of the rail to prevent it from moving vertically. The back rail and the footrest may be supported by cables in the same way as the front rails.</p> |
