April 18, 1939. R. wl SPRINGER I ANTISQUEAK STRIP Filed June 27, 1955 Z ZZ 4 ATTORNEYS.

Patented Apr. 18, 1939 UNITED STATES A PATENT OFFICE 5 Claims.

Myinvention relates to improvementsin antisqueak strips or welts as used between adjacent structural parts of an automobile.

An object is to provide an anti-squeak strip which is simple, inexpensive, moisture resistant and is adapted to be disposed between two metal parts such as external parts of an automobile body or chassis to eliminate the noise and squeak produced by relative movement of the metal` 2 ture.

An important feature of my improved strip is that it comprises a web which is preferably formed of a plurality of layers of inexpensive o loosely integrated fibrous material, such as burlap, which is a coarse woven fabric impregnated with a rubber compound in aqua solution such as latex compound which preferably fills the interstices of the fabric and forms a moisture resistant coatingabout the individual libers that make up the same and renders the fabric and its individual component fibers moisture resisting. The latex furthermore secured the several layers of the material together so that the web is free of stitching or other stiff securing means.

The bead, which is preferably formed of a cord extending along one margin of the web and covered with suitable finish material which overlaps the web adjacent to the bead and is adhesively secured in place. The layers which make up the web are preferably spread apart slightly along one edge forming a channel or groove within which the cord is disposed so that the cord is partially but not completely embraced by these layers and is adhesively secured in position thereto.

Other objects, advantages, and meritorious features of my improved structure will more fully appear from the following specification, appended claims, and accompanying drawing, wherein: v

In carrying out my invention I prefer to form the web of the welt of a plurality of superimposed layers of loosely integrated brous material. Material such as burlap has been found suitable. 'I'his material is thoroughly impregnated with a suitable latex compound such as is described in my copending application Ser. No. 703,853. This latex compound renders the material moisture resistant and upon pressure being exerted upon the layers urging them together serves to adhesively secure the several layers together to form an integral web structure. In place of the latex compound suitable rubber compounds in aqua solution, now on the market, may be employed. These adhesives while not so water resistant as the latex compound described resist the attack of moisture and are less expensive than the latex compound described. Such a web structure is indicated in the several figures of the drawing by the numeral I0. 'Ihe interstices of the material which make up the web structure have the latex compound extending-therethrough and this compound covers the individual bers which make up the web so that they are rendered substantially moisture resistant and adhesively secured together. The latex serves as a connective tissue to adhesively secure the several layers of the web together as well as forming a film over the outer surface protecting the same against .moisture The compound is preferably of such a character that it remains tacky for a considerable period of time.

In Figs. 1 and 2 I exhibit a preferred form of my invention wherein the web is formed of two layers l2 and i4. These two layers are spread slightly apart along one margin and a ycord I6 is placed Within the groove or channel formed along said margin by the spreading apart of the layers as shown in Figs. 1 and 2. This cord may be formed of fiber, paper, or the like. The mare gins of the two layers partially embrace the cord but do not extend completely thereabout as shown in Figs. 1 and 2r The cord is adhesively secured in place. Adhesive may be applied The strip as a unit is moisture resistant.

thereto so that it will adhere to the adhesive coated surfaces of the web material.

A strip of hard surface finishvmaterial such as artificial leather or the like, indicated as I8, is folded over the cord as shown in Fig. 1. It overlaps the adjacent portions of the web. It is adhesively secured in place about the cord and to the opposite sides of the web. This forms the complete strip wherein the cord is denitely positioned by the spread apart margins of the two layers that make up the web and the several parts oi' the strip are all adhesively secured toget'llieraxr.

e web is adapted to be disposed between abutting metal surfaces to prevent squeaks or noise arising from their relative movement. 'I'he bead formed along one margin by the covered cord is adapted to overlie the joint of the metal parts.

In Fig. 3 a slightly modied form is shown wherein the two layers I2 and I4 which make up the web are impregnated with and adhesively secured together by the adhesive compound as described in connection with the construction of Figs. 1 and 2. 'I'hese two layers, however, are not spread apart in the margin as is the structure of Figs. 1 and 2, but abut the cord I6 and the cord is adhesively secured thereto. The finish material I8 is adhesively secured in place as is described in conjunction with the construction of Figs. 1 and 2. y

Fig. 4 is similar to the construction of Fig. 3 except that in this case the web is formed of a single layer of material indicated as 20. This layer should be of a' suitable thickness and texture to serve its purpose and the cord is adhesively secured to the edge thereof. 'I'he inish strip I8 over the cord presents a ilnished bead along one margin of the web as has heretofore been described. y

Fig. 5 diiers from Fig.' 1 in that in this iigure of the drawing the web while formed of the two layers I2 and I4 has one layer adhesively secured to the cord along its edge but in abutting engagement therewith as is the case in Fig. 3 while the other layer is extended partially about the cord as shown so as to form a particularly secure connection therewith extending partially about the cord and adhesively secured thereto.

In Fig. 6 the construction comprises three layers of material I2, I4 and 22. 'I'he intermediate layer is of less width than the two outer layers and the cord I6 abuts the edge of the intermediate layer and is adhesively secured toit. 'Ihe two outer layers partially overlie the cord and are adhesively secured thereto as is the case with the structure of Fig. 1.

In Fig. 7 the construction embodies one layer of material shaped or bent along one margin to form a flange-like portion 24 to which cord I 6 is adhesively secured. Such a construction aords a particularly secure connection with a minimum of material.

What I claim is:

i. A welt comprising two superimposed layers of loosely integrated fabric impregnated with and adhesively secured together by a moisture resist-,f

ing adhesive compound, of rubber in aqua solution, said layers being spread slightly apart along one edge forming a channel along said edge, a cord extending along said edge having a diameter greater than the depth of said channel and seated within said channel and a strip of nish material folded over the cord overlying said layers and adhesively secured thereto.

2. A welt comprising a plurality of superimposed layers of loosely woven fabric impregnated with and adhesively. secured together by a moisture resisting adhesive compound of rubber in aqua solution,at least two of said layers being spread slightly apart along one linear margin, a cord having a diameter greater than the depth of said channel and extending along said margin overlying the spread apart portions of said layers and incompletely embraced thereby and adhesively secured thereto, and a iinish strip folded over the 4cord and overlapping the spread apart portions of said layers and adhesively secured thereto.

3. An anti-squeak strip comprising a web formed of at least three superimposed layers of material impregnated with and adhesively secured together by a moisture resisting adhesive compound, a cord extending along one linear margin of the web and adhesively secured to the edge of the intermediate layer of said. three layers, said other two layers each extending beyond the edge of the intermediate layer and incompletely around said cord and adhesively secured thereto, and a strip of finish material folded over the cord and overlapping the web adjacent to the cord and adhesively secured in place.

4. An anti-squeak strip comprising a web includng a layer of loosely integrated brous material impregnated with a moisture resisting adhesive compound which extends through the interstices of the material and renders the same moisture resisting, said layer being bent along a longitudinal line adjacent to one margin to form an angular ange-like portion along such margin, a cord extending along said margin and adhesively secured to said ange portion, and nish material folded over said cord and adhesively secured thereto and to the web.

5. An anti-squeak strip comprising a web formed of at least two superimposed layers of loosely woven fabric impregnated with and adhesively secured together by a moisture resisting compound which extends through the interstices of the layers and renders them moisture resisting, one of said layers being bent along a. longitudinal line adjacent to one margin to form an angular iiange-like portion along such margin, a cord extending along said margin seating against and incompletely embraced by said ange like portion and adhesively secured thereto, said cord abutting and adhesively secured to the edge of the other of said two layers and a strip o f ilnish material folded over said cord and adhesively secured thereto and to said web.
