WILLIAM J'. BOSSEMEYER,

OF DETROIT, MICHIGAN.

WEATHERPROOF FABRIC.

Application led April 22,

to drying and cracking, abrading, or other factors. Upon such suture the deck material ceases to be Water proof and the car will leak.

Fig. 1 is a cross section of one form of the invention. y

Fig, 2 is a cross section of the preferred form.

Fig. 3 is a perspective of, a piece of the preferred form.

These sections are greatly enlarged and exaggerated, as the finished material will only be about 1/15 or 1/2() of an inch in thickness.

I take a rubberized, or pyroxyline covered fabric which is ordinarily fairly thin, and considered fairly water proof, this is designated a. I then cause to adhere to the undersurface of this by any suitable adhesive, a piece of paper b. I spread over this paper a sticky adhesive water proofing material, such as bituminous pitch, or asphaltum; or for that matter, any suitable organic pitch,l .or other adhesive may be employed. The important factor is, that the material should be substantially impervious to Water and insoluble in water and contain good adhesive properties.

Preferably in this material are spread a large number of hairs, or tenacious fibers. They are preferably laid over each other at an angle which can advantageously be substantially at right angles.

Over this coating of adhesive I lay a sec- 0nd coating of pape-r. If desired the pitch and paper layers may be repeated as many times as seems necessary to, but I find the number of layers that I have specifically referred to, make it very strong and suitable decking material. y

However, I have found that it is preferable to use a crepe paper -as illustrated in Figsf2 and 3, for this paper is extensible without rupture, which is advantageous in a deck material, as this material is subjected to considerable stretching in the tacking operations and it is therefore desirable to' 1926. Serial No. 103,828.

have a web material that will not rupture, and also it is very desirable to have a fabric which is capable of a certain amount of stretching or yield, so that when the same is tacked in place under tension that it will always keep its position by reason of being under a permanent tension.

The hairs, or fiber, Will reinforce but, of course, can be omitted.v However, I prefer to use them as it gives greater strength. I

also prefer to use an adhesive such as pitch which is at a proper consistency, so as not to harden but which will be, under ordinary conditions, always sticky, or witha limited plasticity. This. is an important factor in giving the webbing a certain capacity to stretch even when reinforced with thehai'rs, or fibers. It will be apparent that when the pitch has a limited elasticity that the Vhairs canimove slightly in the pitch Awithout rupturing the material and therefore can give strength to the material without giving it such resistance to stretching as to cause rupture.

A great advantage of this material is thatit is under all ordinary conditions absolutely Water proof, for if the pitch is laid on in an uninterrupted, fairly thick coat, it forms a coating impervious to water and also insoluble in water, and it `will not make a great deal of difference whether some of the rubf berized, \or pyroxylined coating exterior comes off'. If desired, even the paper may be ,water proofed by soaking it in any suit able-water proofing material, such as some thin bituminous composition. y

In Fig. 2, I have shown the preferred `form of my weather proof fabric. I take a weather proof coated fabric as designated and I then lcause to adhere to the under surface of the weather proof coated fabric by any suitable adhesive, a piece .of embossed or crepe paper. I spread over this embossed or crepe paper a sticky adhesive water proof material such as bituminous pitch or asphaltum or any other suitable pitch which is impervious to water and adhesive. In this material are spread a large number of hairs or tenacious fibers, then over this coating of adhesive organic pitch, I lay a second coating of embossed or .crepe paper as desi nated in Fig. 2. The pre-` ferred form o .this Weather proof fabric as shown in Fig. 2, owing to the embossed or crepe paper, is extensible without rupture,

l. A Water proof material comprising a Water proof coated fabric, a layer of crepe i paper adhering to theinside of the fabric,

a layer of Water proof pitch spread over the crepe paper and having strands of fibrous material imbedded therein, and a layer of crepe paper laid over the pitch.

2. A deck material for automobile tops or the like Which comprises, a layer of fabric provided With a Water-proof coating on its exterior surface, a layer of Water-proof adhesive material lying beneath the fabric, and

-a layer of paper under-lying the adhesive material which confines the adhesive material to retain the same in place.

3. A deck material for automobile tops or Y the like which comprises, a layer of 4fabric provided with a Water proof coating .on its exterior surface to make it water proof, a

material with the several layers secured together by the adhesive qualities of the bituminous material, said paper being substantially impervious to the bituminous material for confining the same.

5. A deck material for automobile tops or the like Which comprises, a layer of fabric provided with a Water-proof coating on its exterior surface, a layer of adhesive bituminous material covered both above and below by extensible paper to retain the bituminous material in place, Withthe upper layer of paper secured directly to the inner surface of the .fabric and With the lower layer of extensible paper exposed.

6. A deck material for automobile tops or the like which comprises, an exterior layer of water-proof material, a layer of adhesive Water-proof material underneath the exterior layer, and a layer of extensible paper on either side of'this layer of adhesive material with one layer of paper underlying the exterior layer, with the other layer of the paper being the exposed bottom layer, said extensible paper being substantially impervious to the layer of adhesive material whereby such layer is confined and heldin place and said extensible layers of paper permitting the deck material to be stretched lWhen applied to an automobile top.

In testimony whereof I aHix my signature.
