PACKING FOR HOODS OF AUTOMOBILES.

Application filed December 26, 1924.. Serial 1T0.- 758,018.

To (ZZZ whom may concern."

Be it known that I, GEORGE E. CUTTING, a citizen of the United'States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Packing for floods of Automobiles, of which the following is a specification. 7

This invention relates to the anti-rattling packing used on the edge of an automobile cowl and radiator for securing a comparatively tight joint with the hood and preventing rattling.

The principal object of the invention is to provide a form of packing adapted to be used in substantially the same way as the packing ordinarily employed which will prevent two metal surfaces coming together and thus eliminating practically all the metallic sound due to the vibration.

Another object of the invention is to provide a packing of this kind in which even after considerable wear the metallic surfaces necessarily present will not come into contact with each other and to provide a durable and neat construction.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a perspective view showing an automobile hood partly open with a preferred form of my packing on cowl;

Fig. 2 is a face view of a strip of the packing' showing it in position on the cowl:-

Fig. 3 is a sectional View onthe line 33 of Fig. 2.

Ordinarily the cowl 10 and radiator of an automobile are provided all around the inside edge with a strip of soft material of uniform thickness held in place by brass rivets or split pins. -This soft material comes in contact with, the metallic surface of the hood and is intended to seal the joint between them andprevent vibration of one independently of the other. But evidently that is something that cannot be entirely prevented andthat vibration results in the rivet heads coming into contact with the metal of the hood. The impact of one metallic surface against another causes a disagreeable rattling sound which increases as the car grows older. As heretofore con; structed,this packing has been of such a nature that the heads of the rivets projected beyond it and therefore necessarily into contact with the metal.

According to my construction, I weave a mobile hood consistin narrow tape of suitable thread or yarn in such form that it has a pair of longitudinal edges 11 of considerable thickness connected across the center by a strip 12 of very much less thickness and having a body of thread 14: woven into the two edges inside the exterior surfaces thereof and thus forming a thick packing cushion along the two edges of the fabric. I utilize the central portion for inserting the rivets 15 and their heads 16 lie entirely in this central portion below the raised surfaces of the two edges and in engagement with the thick edge portions, as shown in Figure 3. These are soft surfaces which may be compressed somewhat inwear but they alwaysbxtend beyond the surfaces of the rivet heads and protect them from contact with the metallicsurface of the cover. In this way there is no contact of metal with metal and no vibration which is et up between the parts will result in one metal knocking against another. Therefore till the rattle is entirely removed and this condition prevails even after long usage and wear.

The tape which I have described can be woven on an ordinary narrow fabric loom and after the loom is set up for that purpose the expense of making the tape is comparatively small so that there is very little expense added to the cost of the car.

This constitutes an eflicient and durable means for preventing a disa reeable rattle which has een the source 0 much annoyance heretofore and it can be used for similar'purposes generally in other arts.

Although I have. illustrated and described only a single form of the invention, I am aware of the fact that modifications can bemade therein by any erson skilled in the art without departing rom the scope of the invention, as ex ressed in the claims.

Therefore I 0 not wishto be limited to the details of construction herein shown and described but what I do claim is 1. An anti-rattling packing for an autonarrow fabric tape thicker at-the edges than along the center, said'thicke'ned edges belng fiat spaced apart and projectin abruptly above the plane of the center w en in use of a piece of woven tape consisting of a compact woven narrow fabric having a thickened woven fiat portion along each edge throughout its length, and

a comparatively thin flat portion extending contact at their edges with them and below the outer surfaces of the thick portions.

3. The combination of the cowl ledge of an automobile, with headed fastening devices passing therethrough and a packing strip along the cowl. ledge consisting of a narrow woven tape having a pair of continuous intergx'al thick portions along its opposite edges, and an area thinner along its center, spacing the thick portions Wide enough apart on opposite sides of it in the same plane to just receive between them the heads of fastening devices for securing it in position so that the heads .will assist in keeping the packing straight by engaging the inner edges of the thick edge portions.

In testimony whereof .l have hereunto atfixed my signature.

GEORGE B. CUTTING.
