(Cl. 28o-152) Claims.

5 of' the parts. They are widely used in the automobile industry and particularly in automobile bodymconstruction.- One specic use is between the fender and the adjacent body portion.

Such strips include a web portion and a marginal bead portion. The web portion is adapted to be inserted between the two adjoining metal parts. The metal parts are secured together through this web porti-on. The strip is so positioned between the metal parts that the bead portion extends along and overlies the joint between the metal parts. The bead has a finished outer surface so that it presents a neat finished appearance. My invention relates to improvements in strips of this type. One object of my invention -is the provision of a strip of this 'nature which is inexpensive, which is waterproof, which is yieldinglycompressible and resilient, and which is adapted to seal the joint between the two metal parts and further to seal itself adhesively across said metal parts preventing the ingress of dirt or Water into the joint between said parts.

A characteristicy of my invention is that the web width which is disposed between the adjoining metal parts is impregnated with latex which forms a connective film filling the interstices of i the material and extending in the form of a water proof envelope over the outer surface of the web. In addition, it renders the web compressible and resilient and it further seals the opposed surfaces of the web width against the adjoining metal faces preventing the seepage of water into the joint.

Other objects, advantages, and meritorious characteristics of my invention will more fully appear from the following specification, appended claims, and accompanying drawing, wherein:

Figure 1 isa perspective of 'my improved welt partly unfolded to show the structure,

Figure 2 is a cross sectional View transversely of the welt shown in Figure l, and

Figure 3 is a sectional View through a fragment of a body structure showing the employment of my invention.

My improved anti-squeak strip is formed of va width of. webbing of suitable fibrous material.

I prefer to employ a loosely woven brous material such as jute webbing. 'This material is impregnated with a suitable latex compound.

The latex compound is allowed to set to a tacky condition and the strip is then folded over a cord or the like, indicated as I0. This cord may be est formed of twisted paper or any other suitable material. The strip is brought together over the' cord and the separate folds are pressed together. This operation results in the formation of a double thickness of material i2 extending away from the cord in the form of a web.

As a result of the'impregnation with the latex compound and the compressionl of the folds together the web portion l2 is thoroughly impregnated with the latex and the interstices thereof are filled with such compound.

The latex extends as a film between the two layers of the material. It extends as a film over the outer surface of the web. It forms a resilient connective film enveloping the web.

A strip of finish fabric I4, such as'artiflcial leather or the like, is then folded over the covered cord as shown. This finish strip is adhesively heldin place thereover and upon both sides of the web as illustrated. The latex compound which was used to impregnate the web adhesivelyV secures this strip in place. An additional layer of adhesive may be used underneath said strip if found desirable. It is unnecessary to employ any stitching or any other securing means in a construction of this character. Adhesive com# pound is sufiicient to secure the several parts of n the finished article together.

The latex` compound is utilized in a sufficient quantity so that it renders the web yieldingly compressible and resilient.

In the drawing the complete strip is illustrated as disposed between adjoining metal parts I6 and I8 which are held together by fastening means 20. The stripv completely seals the joint between-such parts filling the irregularities of the opposed surfaces of the parts. In addition, it seals itself against the adjoining surfaces of themetal parts. Along and adjacentvto the bead it is present in such an amount that it forms a yielding cushionlike layer that fills the spaces between the metal parts at the entrance to the joint. Should any water seep in, however, it vwill not penetrate suniciently to rust the metal parts or rot the fabric material as the two surfaces of the web portion are sealed against the opposed adjacent metal faces.

The impregnation of the web 'material and the. compression of the double thickness thereof forms a web portion which possesses sufficient stiffness so .that it is self-supporting. It is stiiily selfsupporting so that itmay be readily inserted within relatively limited spaces between the metal parts, yet it is sufciently fiexible and compressible to accurately conform to irregularities of the surfaces which it adjoins.

A suitable latex compoundl may be formed of 5,0 c. c. m'. of rubber latex, 4 c. c. m. of saturated Burgundy pitch solution, and 20 drops of Neo-` zone L.

'I'he amount of the saturated Burgundy pitch solution may be varied up to 6 c. c. m. with the amount of latex set forth above and the Neo' zone L may be increased up to 60 drops in the f schedule' set forth above.

. layers being compressed together with the latex adhesively securing them together and forming a permanently tacky moisture resisting iilm extending over each outer surface of the web and a film extending between the two layers constituting the web and through the interstices of the two layers, and a finish strip folded over the folded edge of the web and adhesively secured thereto.

2. Ah anti-squeak strip comprising a loosely woven web width so impregnated with a suitable latex compound as to form a latex coating over 'the individual bers of the web material, said width of material folded lengthwise upon itself into a double thickness'web and compressedv together, said latex compound adhesively securing the folds of the material together and forming a film therebetween and a film thereover and extending through the interstices of thematerial, a cord extending between the folds along the fold line, and a strip of hard surfaced finish material folded over the folded edge of the web and adhesively secured thereto by the outer coating of latex on the web width, said web width containing sufficient latex characterized by being nor- .mally tacky to render the same sufliciently stiff to be self-supporting while retaining yielding flexibility and resiliency.

3. An anti-squeak strip comprising two superimposed layers of loosely woven fibrous webbing impregnated throughout with a latex compound forming a latex covering enclosing the individual fibers which make up the webbing;` a cord extending along one linear margin of said superimposed layers, said layers being compressed together and held together by the latex compound with which the layers are impregnated, said latex compound extending between said layers and through the interstices thereof to the outer surface of each layer rendering the two layers and the individual fibers which make up the same water-resisting', and rendering said two layers suiiiciently rigid to be self -supporting as a unitary structure, and a strip of finishing material folded over said cord and adhesively secured to the opposite surfaces of said superimposed layers.

4. A welt comprising a bead filler, a strip of loosely woven fabric impregnated with a latex compound and folded over the bead filler so as to provide a bead at one edge of the welt with a leg projecting therefrom, and a finish strip folded over said bead, said latex compound adhesively securing said folds together and said finish st'rip to said bead portion.

5. A welt comprising a bead portion, superimposed layers of loosely woven fabric impregnated with and adhesively secured together by a latex compound and adhesively secured by the latex compound to the bead portion so as to pro vide a bead along one edge of the welt with a web projecting therefrom, and a finish strip folded over the bead and adhesively secured thereto and to said layers.
