7 Claims.

Our invention relates to fender welts, i. e., cushioning. strips adapted to be interposed be-' I tween certain sheet metal parts of automobiles, such as between the body and fenders, to prevent squeaks, rattles, etc. ,An important object of the invention is to providea fender welt having an ornamental weatherproof exterior portion and an efficient cushioning and sound-deadening in- I terior portion.

Further objects are concerned with generally improving the durability of the sound-deadening portion under adverse'conditions consequent upon loosening of the juxtaposed metal parts and relative movement of the same, resulting infrubbing A further important object is the provision of "a fenderv welt'st'ructure the sound-deadening portion of-which can be readily made in any desired thickness to suit the exigencies of particular ingo stallations and preferences.

' Another object is to provide a fender welt of materials which are inexpensive, efficient and durable, which can be satisfactorily die cut, and which 'wlll'possess a high degree of flexibility.

.25 An important principle of the invention resides in the use, in the cushioning or sound-deadening portion of the welt, of a crimped or crepe paper, employed preferably ina plurality of plies bonded together by'a suitable waterproof adhesive and filler. We have found that crepe paper, the particular character of which will be more fully explained hereinafter, possesses certain important properties which render it definitely superior to any cushioning material which, so far as we are an aware, has ever been heretofore used in fender -welt constructions. In its broad aspects the invention contemplates the use. of this type of paper; and in certain embodiments of the invention the paper is specially folded and is associated to with other elements of the welt in a particular fashion to produce a structure having certain additional advantages, as will be explained hereinafter. I I I The invention is shown in certain preferred 45 forms of embodiment in the acompanying drawing, in which each of the figures is a perspective view,showing one end in cross section, and in all of which the's'ame reference numerals designate corresponding parts.

In the drawing, Figs. 1 to 4, inclusive illustrate various formsof the fender welts proposed by our invention, and Fig. 5 shows, on an enlarged scale, a fragment of theorepe paper material which constitutes an important element of the construc- I 55 tion. I l

Referring now to the drawing, the reference numeral l designates generally the external portion of a fender welt, i. e., the beaded edge which is exposed to view and to the weather when the interior portion, designated by the reference nu- 5 meral 2, is interposed in operative position between adjacent and generally parallel surfaces of two metal bodies, as for example an automobile body and the attaching flange of a fender.

'The portion i is conveniently made beaded, as

tance from the bead filler to receive and support the sound-deadening material which comprises an important element of the interior portion 2 of the welt, and the other ply of the bead-covering fabric, designated 6 in all the figures, extends a much shorter distance from the filler. The sound-deadening material is interposed between the

piles

5 and 6, which may be stitched together, preferably close to the' bead filler, as shown at I in Figs. 1, 3, and 4, or these two plies may be secured to the sound-deadening material by the use of cement only, as shown in Fig. 2.

The sound-deadening material which forms the important and operative part of the portion 2 of the welt is, according to the principles of our invention, built up of crepe paper employed in a plurality of

superposed plies

8, 8. Crepe paper is paper having a multiplicity of surface irregularities, comprising alternate juxtaposed ridges and depressions of more or less minute but readily discernible character. As a rule, the paper is orig- 40 inally smooth-surfaced and of uniform thickness and is subsequently creped' by causing it to pass between rollers which introduce the characteristic surface folds. This type of crepe paper is shorter in at least one dimension than the original sheet from which it was formed, and it is freely extensible in the direction of that dimension when placed under tension to straighten out the crimps or folds. This type ofcrepe paper, shown in Fig. 5, is the form preferred for the sound-deadening element of our invention, but we may use a paper of a somewhat different type, i. e., one which has been originally calendered to provide the desired surface elevations and depressions. It is to be understood that the

term

8, 8, securely bonded together by an adhesive such as a latex or asphaltum compound, which is weather-resistant and more or less permanently flexible. The portion 2 of the welt is capable of being provided in any desired thickness, within a relatively wide range of limits, to suit different installations and manufacturers preferences, by the simple expedient of using plies of paper in greater or less number. This feature constitutes a distinct advantage of our invention and overcomes the difiiculty hereto fore experienced with welts in which the portion to be interposed between the metal surfaces of Tex- I the automobile was made of textile fabric. tile material suitable for use of this kind is inherently thicker than the paper which we employ, and it is not practical to use it in more than a single ply, exclusive of the attaching ply of coated fabric. Attempts to providecushioning portions of multi-ply textile fabric have been uniformly unsuccessful because the resulting body was in the great majority of cases either too thick or'too thin. No knowntextile fabric having cushioning properties and the requisite strength is available'in sheets of sufficient thinness to permit accurate gauging 'of' plural ply thickness.

" We are aware of the disclosure in United States Patent No. 1,808,259, issued to Robert C. Schemmel on June 2, 1931, of the substitution of 'aply of a relatively heavy grade of paper for the customary textile fabric of the internal portion 2 of the fender welt. Our present invention is to be distinguished from, the paper ply of the Schemmel patent in several important respects. The Schemmel paper was a relatively heavy grade, was smooth-surfaced, and was employed in a single ply only. Its thickness prevented i'ts use in plural plies, and in every respect except cost it was indistinguishable from the common textile fabric which it supplanted.

The portion 2 of our fender welt, formed as hereinabove described, is a cushioning body of relatively g-reat compressibility, characterized by .a surface having a multiplicity 'of' alternate depressions and elevations. The cushioning body is exceedingly durable, and is very securely united to the bead portion I ,by the ply -which backs and supports it.

A good fender welt must be flexible and capable of being readily curved in the-f plane of its web portion without appreciable distortion thereof. This is necessary to accommodate the welt to the curved contours of automobile" fenders and the like. 'An important advantage of our composite crepe paper body is its possession of these two qualities in high degree, practically without regard to thethickness to which th body may be built up.

In the form of the invention shown in Figs. 1 and 2 the sound-deadening material is disposed on one face only of the skirt or web portion of the welt. Fig. 3 illustrates a modification in which the multi-ply body is originally provided in twice the width desired for the skirt. Half of the body-is folded back on itself, with the portion 5 of the covering fabric for the bead filler interposed between the two halves. There is thus provided a resilient, yielding, sounddeadenlng surface of both sides of the web.

In Fig. 4 a further modification is shown. In this form of the invention the portion 9 of'the bead filler covering fabric 3 is made somewhat narrower than the portion 5 shown in Figs. 1-3,

and the plural plies of sound-deadening material I are made somewhat wider than as shown in Figs. 1 and 2 and somewhat narrower than as shown in Fig. 3, so that a portion of the plural ply body may be folded over on itself and its edge butted against the extreme edge of the portion 9. The plies of sound-deadening material may be made as thick as, or somewhat thicker than, the'ply 9, so that when the welt is compressed between the two metallic surfaces both surfaces of the metal will be separated by the sound-deadening material. The Fig. 4 form of construction has the advantage, possessed also bythe Fig. 3 construction, of providing a cushioning surface for both metal surfaces, and in addition it has the advantage, lacking from the Fig. 3 construction, of presenting no exposed raw edge of multi-ply material adjacent to the bead I, which of course in practice is exterior of the metal parts and exposed to the weather.

Figs. 1 to 4 inclusive may be regarded as showing complete fender welts ready for perforation to accommodate the usual bolts which secure the metal parts together, or they may belthought of as blanks which can be die cut or otherwise operated upon to'transform the web'portions 2 into tongued or pronged strips, as contemplated by the'Drangeid Patent No. 1,760,838 and the Schemmel Patent No. 1,808,259.

The welt is applied in the usual manner between the fender flange and the body and the customary bolts are drawn tight, compressing the down its elevations. Theyieldability and resilience of the superposed plies of paper and adhesive are such that the somewhat diminished thickness of the worn body remains great enough to cushion the metal parts, and there is no fraying or tearing of the cushioning body or the fibers thereof such as occurs. when woven .material wears under similar conditions of use.

It is believed that the principles of the invention'will be understood from the foregoing description of certain preferred forms of embodiment. It is to be understood that the invention is capable of embodiment instill further modified forms, and all such, modifications, to the extent that they incorporate the principles of the invention as defined by the appended claims, are to be deemed within the scope and purview thereof.
