A TTORNE Y 1 LESTER} 'N. wnnniafor CHICAGO, ILLINOIS, AssIGn'on T0 AMERICAN VREENFORCED Patented Aug. 16, 1932 PAPER. coMrANY, OF ATTLEBOBO, MessAcHUsEr'rs, A conroaa'rion or MessieoHUsET'rs f s TA PA LIN Qix fncation' filed January 21, 1931'. Serial No. 510,120.

This'invention relates to a Waterproof covering. sheet or tarpaulin. formed of reenfor ced paper;

"Tarpaulins are extensively used on land and aboard ships to cover and protect various objects, and as commonly constructed are made of waterproof canvas. 3 They-are usually relatively large and are comparatively expensive due tothe number of 'yards of canvas required in theirconstructlon,

The present invention therefore relates to a modified tarpaulin or covering sheet formed of waterproof reenforced paper that is strong enough to withstand the forces to which the covering sheet is likely tobe subjected, and to the construction'whereby the marginal edges of the sheet may be tied down with anchoring ropes without tearing the paper. 1 r s WVhen tarpaulins are employed'to protect Objects from the weather it is necessary "to secure the tarpaulins firmly in pl'ace-to' prevent them from being pulled loose'orcarried away by the wind, and an important feature of the-present invention-therefore resides in very good results are securedby employing a two ply paper having the sheets of paper united by a waterproof 'adhesive such 'as black asphaltumand reenforced withfunspun fibres of long staple secured between the sheets, by the adhesive and which are capable of withstanding the strong pull'of the anchoring ropes.

A' more specific feature of the invention resides in means for reenforcing the sheet of'paper in the area of'the grommet, and

;in covering .means for excluding rain and moisture at this point.- Th'eaboveand other features of the invention will be hereinafter described in connectioniwith the accompanying drawings whichillustrate one tical' form of the invention.

In the drawings l I Fig. 1 a plan View of a tarpaulin constructed of reenforced waterproof paper in accordance with the present invention.

good prac Fig. 2 on an enlarged scale is a plan View a of a portion of the tarpaulinof F ig. 1 showing theconstruction of a grommet; and

' F ig. 3 is asectional view taken on the line 33 of Fig.2. i

The covering sheet or tarpanlin of the presentinve'ntion' is illustrated in'the drawings a as formed of a multiply reenforce'd paper comprising theiupper sheet of paper '2 and a similarlower sheet of paper 3. These sheets of paper are secured together by a waterproof adhesive, such as black asphaltum, and the dinally and transversely by layers 4 and 5 of straightened unspu'n' fibres, such as sisal which are relatively strong and" will not stretch or elongate appreciably under tension. While other forms of reenforced' waterproof paper might be used in carrying out thefeatures'of the present invention-the reenforc'ed paper shown and described is particularly well adapted for the present use becausethe asphaltum serves to firmly unitethe sheets of paper 2 and 3 to render the composite sheetv waterproof, and serves also to firmly secure the reenforcing fibres to the sheets of paper so that the tension or pull exerted upon the paper will be taken up by the fibres to pre- Vent the paper from tearing.

.70 paper is preferably reenforced both longitu- It will be understood that the tarpaulin of the present invention may be given any desired size by securing two or'more sheets-of reenforced waterproof papertogether'.

The strength of the edge portions'cf the tarpaulin of reenforced papryis preferably ginal edge portion (i-to the face ofvthe sheet by a waterproof adhesive such asbla ck asphalincreased by folding a marginal edge 'p'ortion 6 thereof back upon the paper as shown in the drawings and by securing this martum. The corners-of the covering sheet'are also preferably folded inwardly as at 7 to'in;

crease the strength of the sheet at this point.. It is important that the covering sheet or tarpaulin ofthe presentinvention be provided with means whereby it may be readily tied .a waterproof adhesive;

or anchored in place over the object to be protected and this isac'complished in accordance with the present invention by providing the desired number of grommets or metalv eyelts along the marginal edges of the covering sheet and at the four corners. Since these grommets are likely to be subjected to a .8 of textile material-folded about the edge portion of the tarpaulin as shown and firmly secured to the opposite faces ofthecovering sheet, preferably by a waterproof adhesive.

It isdesirable to exclude, moisture from the textile material 8 and'thismay be-accomplished by covering the samewith a patch 9 preferably formed of reenforc efd waterproof paper similar to-the sheet 1. This patch shouldbeconsidera bly largerthan the reenforcing sheet 8 as shown and isipreferably folded about the edge portion of the sheet 1 and is adhesively secured to the opposite faces of the sheetthrough the employment of Each grommet or metal: eyelet l0 pref er;- ably passes through the reenforcing sheet 1, folded marginal portion 6, the textile material 8, and also through the outer waterproof ing patch 9, as best shown in Fig.3 and is se-' cured in'place by spreading the inner end portion of the tubular shank 1 1 ofthe grommet outwardly over the disc 12v in a well known manner and as will be apparent from a r t will be seen from thelconstruction just described that. the reenforcingelements 6, 8, and 9 all serve to distribute the'pull'exerted upon the grommet 10 over a substantial area ofthe sheet 1 of reenforced paper, and it will i also be seen that since the grommet passes through the layers 4 and 5 of reenforcing fibres thepull exerted upon the grommet will be imparted directly to these reenforcing elements to relieve the paper sheets 2 and 3 from rupturing strains. The grommets disposed at the corners of. the tarpaulin extend through the reenforcing elements above men- .tioned and also through the inwardly folded corner portion to further increase the strength of the construction at these corners. The anchoring means for the tarpaulin ,suchias ropes13lmay be passed through the grommets as shown in Figs.2 and'3 and may exert a strong pull upon the grommets withrial and paper covering,

ployed for various purposes where a relative- V ly large waterproof covering is desired and that the same is sufficiently strong and durable to withstand repeateduse without tearing. "It will also beseen that thecost of such reenforced papertarpaulin is only a'fraction 1.
