METHOD OF MANU-FVACTURING GAS TIGlxiT MATERIAL Filed Nov. 12. 1927 (1Mo/l ne 13 Patented Oct. 13, 1931 UNITED STATESV lAJrI-:N'r' OFFICE- HANS STRBL, F BERLIN-TEMPELHOF, GERMANY, ASvSvIGNQRV BY AMESLN'E .ASSIGN- MENTS, TO LUFTSCHIFFBAU ZEPPELIN G. M. B. H., OF FRIEDRICHSHAFEN, BODENSEE,
GERMANY METHOD 0F MANUFACTURING GAS TIGHT MATERIAL 'Application filed November 12, 1927, Serial No. 232,942, and in Germany November 29, 1926.
My invention relates to gas-tight material and to the method of manufacturing the same, and it has special reference to balloon `material made of a layer of staple fabric .5. united with skins of animal'provenience, such as gold beaters skins for example.
It is the custom in the manufacture of such material first to provide the staple fabric layer and then to glue to this layer individual skins thereby forming a layer of such skins or to have a separate layer of skins prepared which is then glued to the fabric.
The agglutinant -used for uniting Hfabric and skins has to be hygroscopic. Part of this glue gets into the pores of the skins and serves for improving their gas-tightness. Another portion of thev glue fills the spaces in' the staple-fabric and it may even permeate right through the fabric layer to its other surface. In all events this hygroscopic glue in the fabric, open to Weather influences, 1s a great disadvantage to the quality of the material. In dry Weather such material is sure to be rather hard and brittle, whereas Wet lweather will cause a big increase in the Weight of the material. But such material ought to be free from Weather influences or at least weather changes should have only very small influence on the material.
It is the primary object of my invention, to improve these conditions.
It has been tried to cover the outer surface of the staple fabric layer after the union with the animal skins with a coating-of'varnish, but this method has not had muchsuccess. It has also been tried to make use of an agglutinant which is less hygroscopic such as rubber for example, but such a glue hasthe disadvantage that it does in no way contribute to the gas tightness of the animal skins.
According to my invention, I improve the quality of the gas-tight material and do away with the above mentioned drawbacks by applying the following method of manufacture illustrated by the accompanying 'drawing which constitutes a part of this specification I take the staple fabric layer 10 and provide it from one surface with a water resistant coating 11 or I impregnate the` fabric with a water resistant substance. After this4 prepwhich a substance may-be admixed, adapted to render the glue soft, as for example glycerme, Turkey redl oil or the like.
. In case an impregnating substance is made use of which does not unite with the agglutinant, precaution has to be taken, that the inner'surface of the fabric remains free from the impregnating substance.
By the described method of manufacture a product is attained which in its-qualities, especially with regard to its use in aiships, ranks far above the materials, known at present for this purpose.
What I claim is:
l.. A method of manufacturing gas cell material which comprises impregnating a layer of fabric by applying a weather-proofing substance on one side thereof and subsequently gluing animal skins to the other side of the fabric by means of a hygroscopic agglutinant for` rendering the material impervious to gas, said agglutinant also serving to close the pores of the animal skins. I
2. A method of manufacturing gas cell material which comprised impregnating a layer of fabric by applying a cellulose product on one side thereof Whilemaintaining the surface of the other side of the fabric free from the impregnating material, and subsequently gluing animal skins to the last-mentioned side of the fabric by means of isinglass admixed with glycerine. e A
3. A ga? Il material for aircraft comprising a layer of fabric, a weather-proofing material disposed in the form of a coating ,on one side of the fabric and substantially fil-ling the interstices thereof, and a layer of sldns of be some glue consisting v 2 mmm@ animal provenience having a, hygroscopic coating thereon, said coating serving as a glue for cementing the skins to the other side of the layer of fabric, said Weather-proofing ma,- terial resisting penetration of the hygroscopic coating inbo the interstices of the fabric.
