Claims.

This invention relates to metallic tire covers and more particularly to a beading therefor and the method of applying the same to the cover.

An object of the invention is to provide a simplified form of beading for a tire cover which permits of the economical manufacture of the cover and which not only enhances the appearance of the cover but also serves to strengthen and reinforce the cover.

Another object of the invention is to provide a beading for a cover of such formation as will permit'of the introduction of a decorative strip in the beaded portion of the cover after the cover has been fabricated whereby a strip of any desired finish or color may be secured to the cover, which strip may be in accord with the taste of the party applying the same to the cover or may be in accord with the appointments of the car or vehicle to which the cover is to be applied.

Still another object of the invention relates to a novel method of forming the bead construction on the cover whereby a mounting for a decorative strip is rolled, spun or otherwise formed in the cover at the same time the cover is fabricated so that after the cover has been completed a decorative strip may be inserted in this formation and retained therein without the necessity of using any fastening or securing means for holding the strip in place.

In accordance with the general features of this invention there is provided a cover member which has formed in it as an integral .part thereof a plurality of spaced converging slanting ring-like extensions which define an annular pocket into which a decorative strip is adapted to be forced or snapped andretained in the pocket by these extensions.

Another feature ofthe invention relates to the method of forming this bead construction in the cover, which method consists in rolling, spinning or otherwise providing the extensions in the cover at the same time that the cover is formed whereby after the cover has been fabricated a decorative strip may be inserted in thisbead formation be.- tween the extensions .so as to be retained in position on the cover without the necessity of employing any means for fastening or securing the strip in place other than the extensions themselves.

Other objects and advantages of this invention will more fully appear from the following detailed description, taken in connection with the accompanying drawing which illustrates a single embodiment thereof, and in which Figure 1 is a side View of a cover with a bead formation embodying the features of this invention;

Figure 2 is an enlarged fragmentary cross sectional view through a cover such as that shown in Figure 1 in the course of manufacture;

Figure 3 is a view similar to Figure 2 but showing the extensions on the cover as being bent towards each other into their final form to define a pocket for receiving a decorative strip; and

Figure 4 is an enlarged sectional view of the 10 finished bead construction showing the manner in which a decorative strip is retained in place by the slanting and converging extensions on the cover.

The cover shown in the drawing is of the twopart type such as that disclosed in applicants Patent No. 1,807,697 which issued June 2, 1931, and more particularly embodies a ring-like side plate I f! and a split rim or tread covering portion ll cooperable with the plate to hold the same in place. That is to say, the split rim is contractible upon the tire to not only retain itself on the tire but to also retain the plate in position on the tire as disclosed in my aforesaid patent. It is of course understood that the bead formation of my present invention is not limited to this specific form of cover, but may be used with other types of tire covers with equal advantage.

While it is to be appreciated that either the outer peripheral part or the side wall part or both of the cover may be provided with the beading of my present invention, I have in order to simplify the illustration and description of this invention illustrated the beading as being only applied to the side plate portion of the cover.

The side plate I 0 is of ring-like construction and may be fabricated from any suitable stiff material such for example as metallic sheet. This part isrolled, spun or otherwise formed into a ring having a curved convex cross-section, and is provided at its outermost margin with a cushioning strip 12 for engagement with the cover rim ll as disclosed in my aforesaid patent.

In the forming of this ring-like plate, it is provided with a plurality of spaced circular riblike lateral extensionsl3 and I4 disposed on the outer side of the plate. These extensions, as well-as the plate, may of course be formed in any suitable manner, but I find that I can most readily fabricate this structure by a rolling process.

Each of these two rib-like extensions l3 and I4 is formed integral with the plate proper and consists of portions of the plate material bent outwardly from the cover proper and back on itself toward the cover proper. The rib-like beads thus 5 formed define a pocket between them for receiving a decorative strip I5 to be hereinafter described in connection with Figure 4. I

After the rib-like beads I3 and 14 have thus been formed, they are then bent inwardly toward each other as shown in Figure 3 so as to each assume a slanting position and whereby the ribs converge. In other words the ribs are caused to assume a reentrant position whereby a strip retaining pocket [5 is provided between the ribs.

Thereafter a strip of suitable material such for example as stainless steel which has a width slightly greater than that of the pocket l6 may be snapped into the pocket I6 as shown in Figure 4 with its marginal portions in engagement with the reentrant ribs l3 and I4, thus enabling these ribs to retain the strip in place in the pocket. It will of course be appreciated that the flexing of this strip into the pocket l6 causes it to become bowed whereby its marginal edges are at all times urged by the natural resiliency of the material into tight contact with the inner surfaces of the reentrant ribs l3 and 14 thus augmenting the frictional engagement of the strip with the walls of the pocket I6.

This decorative strip may be applied at the time of the fabrication of the cover to the cover part, or it may be applied to the cover at any later desired time. Furthermore, this strip may be of a finish and color other than that of the' cover part with which it is associated, and it may for example be of a finish and color which will blend with the appointments of the vehicle to which the spare tire cover is to be applied. This is an advantageousrfeature since a cover of my invention may be shipped to a car manufacturer where a decorative strip such as the strip [5 may be applied to the cover in accordance with. the taste and requirements of the manufacturer. Then, too, this decorative strip may be finished at the automobile manufacturers plant so as to have the same finish as a part of the vehicle to which the spare tire cover is to be applied.

Now it will be apparent from the foregoing description that the bead construction of my invention essentially comprises reentrant-like ribs defining reentrant openings in the pocket 16 into which the marginal edges of a flexible strip are adapted to be flexed for the purpose of enabling the strip to be retained in place by the reentrant ribs without the necessity of any additional fastening means. Furthermore, this bead construction is advantageous in the cover inasmuch as it enhances the cross-sectional rigidity of the cover part with which the bead construction is associated and thus aids in resisting distortion of the cover part. 7

It is of course to be understood that although I have illustrated and described in detail the preferred embodiment of the invention, the invention is not to be thus limited but only insofar as defined by the scope and spirit of the appended claims.

I claim as my invention: 7
