BALLOON ENVELOPE MATERIAL AND METHOD OF MANUFACTURING THE ,SAME
Filed Jan. 24, 1935 Invenfar:
Patented Mar. 3, 1936 PATENT OFFICE BALEooN ENVELOPE MATERIAL AND METH- on or MANUFACTURING THE sAME Hans Strobl, Berlin-Tempelhof, Germany, as-
signor to Luftsizhiffbau Zeppelin G. m. 'b. H., Fiiedrichshafen, Bodensee, Germany Application January 24, 1935, Serial No. 3,360 -In Germany June 23, 1930 4 Claims. (o1. 154-2) .My-invention relates to balloon envelope materialas-for example for gas cells of gas inflated airships and the like and to the method of manufacturing such material. .The present application is a continuation in part of my application Serial No. 544,167, filed June 13, 193 1.
Lately ithas become usual to-manufacture balloon envelope material from fabric combined with skins of animal provenience, both materials being glued together by an adhesive comprising gelatine; isinglass or similar substances with an admixture of softening substances such as glycerine,-Turkey red oil orthe like. According to my invention I use only staple fabric without any animal skins or the like,but I impregnate the fabric with liquid substances only. First I impregnate the fabric with a substance insoluble in water, such' asindia rubber solution, a cellulose product, for instance cellulose acetate or cellulose nitrate, or the like. This impregnation rendering the fabric resistant against weather influences may be applied to the fabric from one. side only or from both sides; I prefer to impregnate from one side only but to have the interstices of the fabric filled more or less with this first impregnation substance. Nor-' mally the amount of substance applied tothe fabric should be such that an uninterrupted surface layer of such waterproof material results. Of course, instead of substances entirely insoluble in water such substances may be used also E1011 are nearly'insoluble or mixtures of both ingagent such as glycerine, Turkey red oil or Then I provide one side of the impregnated fabric with a second impregnation, this' time composed of gelatine, of casein, isinglass ora similar substance with an admixture of a soften.-
the like. These substances may be applied-as a mixture or separately in' anynumber. of coatings. The weight proportion of the gelatinous material to the softening agent "should be from 50:50 to" 33%;:66%, which means that at least the same weight amount ofsoftening agent should be applied as gelatinous material is used. flhissecond' impregnation which is to bemade on the second surface of the fabric may again be applied in such 'quantitythat a second uninterrupted surface layer of such gastightening substances results. 7 I
At last I add to the material which is now impregnated twice a third layer preferably of fibre or the like, whichisconnected to the other layers by means of'the impregnating substancesthemselves, which can be done by applyingtlns fibre substance for the second impregnation.
.' This second impregnation which is-hygroscopic layer before the prior impregnations have dried, or any well-known adhesive may be used therefor. This layer of fibre may be applied loosely or as a fabric, as circumstances may .aiford. Cotton or linen fibre for example are suitable. for this layer. This fibre layer can be applied toone side or to both sides of the balloon envelope material; if applied to one side only it should be the side which carries the second (gastightening) impregnation, as this needs protection more than the weather=proof surface.
As the first impregnation for rendering the original fabric resistant against weather-influences serves more or less also for filling the interstices of the fabric, this means a reduction in the necessary amount of the gas-tighte1 1]i;11ge third'layer consisting of fibre is most important because it protects the impregnation layer or layers against influences from outside, especially Q0 mechanical influences such as rubbing and the like. It is very valuable to have such protection on the side of the second (gas-tight) impregnation, but if circumstances should afiord both sides may be so protected.
The new material attained by my method of manufacture has great advantages over the old the. material resistant against-weather influ- 3 ences and then both may be united by means of an intermediate impregnation of the second kind for making the material gas-tight serving at the same time for gluing the two layers together.
is thenv enclosed by the weather-resistant coatings so that practically a minimum of water 1 can "only be absorbed.
To the impregnating substances which are subject to decomposition by outer influences 45 (substances: of animal provenience as gelatine Y or the like) I prefer to. make "a preserving agent,. as for instancecreosote or-the like.
In certain cases it may be found desirable'to further .add tothe balloon envelope material '50 manufactured according to the new method of my invention-as explained abovean outer coating ofoil or lacquer, which may be applied a in any well-known manner on top of the fibrous layer and/or on the surface which possibly does 55 quantity of the impregnating substance is assumed to be so rich that the upper surface of the impregnating layer is plane. But of course, in
certain cases it may suffice to apply only so much material that the fabric l is just soaked up toits upper surface so that the surface of the impregnation is wave-like following-the surface of the fabric itself; The second impregnation 3 of the gas-proofing composition is applied to the other side of the fabric. There is a protective layer of fibre 4 assumed to be applied to .both sides of the balloon material.
I do not want to be limited to the detailsdescribed or shown in the drawing as many variations will occur to those skilled in the art.
What I claim is:
1. Balloon envelope material comprising a water-proofed staple fabric, a gas-proofing gelatinous coating including a softening agent and having adhesive properties applied to the side of said fabric, and a wear-resisting layer of fibre secured to the fabric on the gas-proofed side thereof. u
.2. Method ofwmanufacturing weather-proof and gas-tight balloon envelope material which consists in first impregnating a staple "fabric with a liquid water-proofing composition, then applying a gas-proofing gelatinous composition coating to one side of the fabric, and thereafter afilxing swear-resisting fibrous layer to the gas-proofed side of the fabric.
3. Method of, manufacturing weather-proof and gas-tight balloon envelope material which .consists in first impregnating a, staple fabric from one side with a liquid weather-proofing composition,-then applying on the other-side a gas-proofing'impregnation of gelatinous coating material incorporatingv a softening agent; and
thereafter afiixing a protective fibrous layer to the gas-proofed side of the fabric.
4. Method of (manufacturing weather-proof and gas-tight balloon envelope material which consists in first impregnating a staple fabric from one side with a weather-proofing liquid rubber composition; then applying on the other side a gas-proofing impregnation of gelatinous coating material incorporating a softening agent and having adhesive properties, and afiixing to the gas-proofing impregnation through its adhesive.properties a protective fibrous layer.
