1851 Great Exhibition: Official Catalogue: Class VIII.: Edward Bennett
392. BENNETT, EDWARD, 2 Victoria Place, Woolwich — Inventor.
Universal wedge block, in stone, wood, or brick, applicable for piers, dock and sea-walls, foundations, waterwheel aprons, fire-proof floorings or roofings, and all descriptions of furnace work, etc., or for any situation requiring great resistance to lateral pressure. The principle of these blocks rests upon their pure geometrical construction, for a weight or pressure cannot pass beyond the centre of the stones, and they are better than stone altogether solid.
