Description

BEST AVAILABLE COPY CHARLES ALFRED GABLES DE CAUDEMBERG, OF NICEFRANGE.
PROCESS FOR AGGLOMERATING FIBROUS SUBSTANCES.
Specification of Letters Patent.
Patented Nov. 27, 1906.
Application filed May 2, 1906. Serial No. 314.882.
To a, whom it may concern:
Be it known that I, CHARLES ALFRED CABLES DE CAUDEMBERG, doctor of medicine, a citizen of the French Republic, residing at Nice, Alpes Maritimes, France, have invented certain new and useful Improvements in Processes for Agglomerating Fibrous Substances, of which the following is a specification.
This invention has for its object to agglomerate fibrous substances, which may be either mineral ones, as peat, asbestos, or the like, or
vegetable ones, as cotton, linen, hemp, or the like, or animal ones, as horsehair, wool, hair, or the like, by means of a peculiar agglutinative substance.
This invention is based on the following observation: If fibrous substances are im bibed with a solution of weak percentage of bitumen and indie-rubber, andif the mass thus obtained is immerged in a sulfured solu tion of high percentage, this mass rapidly agglomerates and hardens under the influence of the vulcanization.
In practice the fibrous substances which are to be a glomerated are first prepared in the form a apted to their destination by being crushed, compressed, or disposed into molds. They are then imbibed with a solution of bitumen and india-rubber in a suitable dissolvent for instance, heavy benzin. This solution is made in the proportions of two to five per cent. of bitumen and two to five per cent. of india-rubber. Between these limits the proportions of bitumen and india-rubber may be varied, the percentage of bitumen being increased if more hardness is required and the percentage of india-rubher being increased for obtaining more elasticity. The excess of liquid is squeezed out by means of a light pressure. The substances thus impregnated are dipped into a bath of carbon sulfid containing five to ten per cent. of sulfur protor' iorid. The duration of the with the thickness of the nized. Itis ad- 1 :7, a a
closed vessel provided with a pump for first producing the vacuum and after increasing the pressure. The absorption is thus more speedy and more complete, and the results are more homogeneous. When it is taken out from the second bath, the agglutinated mass remains malleable during a certain time, and thus it can be rolled, compressed, or molded in various forms. The heat accelerates and increases the hardening.
The agglomerated substances thus obtained have peculiar properties. Having the same density as the lightest wood, they have the hardness of the most compact bodies. Their resistance to the crushing by shock or by pressure is considerable. They are unassailable by the acids or by the oxidizing substances. They are water-proof and uninflammable. They are not spoiled at the extremes of the surrounding temperature. Their industrial uses derive obviously from tin properties hereinbefore described. Having thus described and ascertained thr nature of my invention and in what manne: the same may be performed, I declare tha' what I claim is l. A process for agglomerating fibrou; substances consisting in impregnating thes' substances with a solution containing two t1 five per cent. of bitumen and two to fi e pe cent. of india-rubber and in dipping th mass thus obtained in a bath of carbon sulfii containing five to ten per cent. of sulfur pro tochlorid, substantially as described.
2. Aprocess for agglomerr" fibrous sub stances consisting in impi l 1g the sub stances with a solution co .g bitume: and india-rubber, and th ecting th material to a bath of carbr utainin sulfur protochlorid.
In testimony whereof my hand in presenceof nesses.
