PAPIER MACHEE. John Cope Houdan, of No. 29, Liverpool-street, King's Cross, Middlesex, Civil Engineer, for *' Improvements hi the mode of manufacturing papier ntachet-j and other articles made of vegetable ;—Granted Nov. 21, 1843; Enrolled May 21, 1844. This invention consists in a mode of combining successive layers of wet pulp, by causing the same to be wound round a cylinder until it has acquired a ihickness sulKcient for the purpose it is intended, alter which it is to be cut from ihe cylinder «ith any convenient instrument. Tlie machine first de- scribed consists of a vat or back conlaining a quantity of pulp, which the in- ventor prefers to be made Irom tine coloured rajjs ; on the edge of this back there are two plummer blocks or steps suiiporting a cylinder covered willi wire gauze, which cylinder is partly immersed in the pulp contained in the back; above this cylinder, anil a little to one side thereof, there is another cylinder ot wood or other suitable material supported by two levers, moving upon an axis at their lower ends ; th
