1851 Great Exhibition: Official Catalogue: Class VIII.: William Randall Vickers
8. VICKERS, WM. RANDALL, 32 Baker Street, Portman Sq. — Designer.
Geometrical floating life-belt, made of sail canvas, and divided into five compartments, stuffed with cork-cuttings. Models of strong sail-canvas, made up for stuffing. Samples of the sail-canvas, and two sample bags of the cork cuttings. The life-belt can be folded up (nearly in the form of a cube) and made to serve as a cushion on board ship. If one of these compartments should be torn, the rest would still form a useful belt. It is made to surround the body of the wearer and leave his arms free.
