in Claims. (Cl. son-37 radially projecting handle or horn structures at the sides of the central crown portionofthe cover. Where a separatecentral cap is provided it is easy enough to draw the horns directly in the margins of the cap. However, where the central crown portion is only a small diameter crown protrusion of a larger cap or cover, material may not be'available about the sides of the central crown protrusion or embossment to enable the provision of drawn or pressed-out horn members.

By the present invention such horn members are provided efiectively as separate, attached structures.

An important object of the present invention is to provide a cover crown with novel radially projecting horn members.

Another object of the invention is to provide a cover having a crown to which are secured in self-retaining relation radially projecting horn members.

A further object of the invention is meansfor connecting horn members to the sides of cover crown protrusions.

Still another object of the invention is to provide an improved method of making wheel covers including central crown protrusions to which radially projecting horn members are attached.

, Other objects, features and advantages of the present invention will be readily apparent from the following Figure 4 is a diametrical sectional view similar to Figure 2 but illustrating various steps in the assembly of the cover components;

Figure It) is a fragmentary detail sectional view taken substantially on the line XX of Figure 8.

A wheel cover 15- (Figures 1 and 2) may comprise a ,hub cap or a full disk type of wheel cover and may be a knock-off cap, as preferred, since the present invention is applicable to any type of cover wherein radially projecting head lugs, wings,-'ears or horns 17 are usable. In a rotary knock-01f type of cap or cover the horns 17 serve the purpose of affording convenient hand holds or grips for angular turning leverage on the cap; On a snap-om, pry-off type of cap or cover the horns 17 may serve only as ornamental, simulative appendages where the cap or cover is intended to afford the appearance of a knock-off cap or cap and cover combination.

As shown, the cover 15 comprises a sheet metal body 18 in the form of a stamping providing a sloping wall 19 provided with a central outward crown projection or protrusion 20 which in the present instance has a circular generally axially but somewhat flaring side wall 21 joining the sloping wall 19 angularly. The cover body 18 may be made from stainless steel or brass or other suitable sheet and it may be plated or polished, burnished, or otherwise ornamentally finished.

As illustrated, two of the horns 17 are provided at diametrically opposite sides of the crown protrusion 20, but it will be obvious that three or more of the horns 17 may be provided, as preferred. The horns 17 project radially from the side wall 21 into overlying relation to the adjacent portion of the outer body wall 19.

The horns 17 are preferably made from sheet metal stamped or otherwiseshaped to form and the material may be the same as that from which the cover body 18 is made or other material may be utilized, as preferred. By preference, each of the horns 17 is formed as a hollow shell having coextensive side walls 22 merging at a tip 23 to provide an outer end closure for the shell, while the opposite or inner end of the shell is open. The horn shell 17 is wider at its inner or open end and tapers towardthe tip 23. The construction and arrangement is such that in assembly with the cover, the shell opens downwardly or toward the adjacent portion of the body wall 19 and with the edges of the side walls 22 closely adjacent to the coversurface.

Assembly ofthe horn shells 17 with the crown side wall 21 of the cover is effected by interconnecting the inner or open end portion of the respective horn shells To this end the crown side wall is provided with respective apertures 24 (Figures 4 and 5 dimensioned to receive the inner end portions of the horn shells in snug relation. The outline of the openings 24 is thus complementary to the contour of the inner end portion of the respective horn shells 17 so that the horn shells can be assembled by thrusting them through the respective openings 24 from the inside of the crown 20.

Interlocking interengagement of the horn shells 17 with the crown side wall 21 is efiected by the provision on the inner end portions .of the side walls 22 of depending locating or stop lugs 25, while the upper inner end portion of the horn shell is provided with an interlock lug extension 27. The outer edges of the depending lug extensions 25 engage against the lower margin defining the opening the crown side wall 21.

In order to retain the horn shells 17 againstinward displacement, the crown 20 is inset adjacent its margin to provide an interlock shoulder 28 which opposes the asaaszs Patented Jan. 20, 1959 r inner side of the respective retaining lug extension 27. The interlock shoulder 28 may be provided as a knockin lug or individual depression adjacent to the respective symmetrical annular inwardly projecting rib defining an outwardly opening *groove-at-the margin of the peak or topof the crowriZtl. 'As-best seen in Figure 4, thecrown top-may originally be formed flat and then rolled or pressed in at its -margin to provide the insetor depressed shoulder 28' after'the horns 17 have been assembled with'the-crown and as a final step in completing the as sembl ed," interlockedrelationship. To facilitate such assembly, the interlock extensions 27 are preferably formed on a radius as shown and in the final assembly fit 'up in a -cornpl'ementary groove 29 in the margin of the crown top'formedbetween-theinterlock rib 2d and the upper margin 'ofthe side wall 21. In orderto brace the inner end portions of the: side walls'22of'the horn shells-againstinward collapsing and also to substantially close on" the apertures -24 against entrance of" dirt'therethrough into the crown '29, after assembly of the horns 17 with the cover, respective closure members 30 areprovided. Herein the closure members 30 comprise integral tongues or flanges struck out in the formation of the apertures 24 and in the preassembly condition extending as integral extensions from the lower margins defining the respective apertures 24. After the respective horn shells 17 have'been assembledwith the 'crown 20, the bracing and closure flange tongues 30 are "bent up into interengaging and closing relatio'n'to the inside of the-inner portion of the associated'horn shell from the inwardly extending position of Figure 4- into the final assembledposition shown in Figure 2. It will be observed that the flanges 3d are cut to an outline that is complementary to the internal shape of the inner end portions of the horn shells.

suitable sheet material stamped or drawn to shape,- having a sloping major wallS and a central crown protrusion it? provided with a side wall 41 which merges angularly with the cover wall 39.

. Each of the horn members 37 comprises a sheet metal shell having coextensive side walls 42 merging to an outer end tip 4-3 and'fiaring toward an inner open end.

' The side wall 41 is formed with appropriate apertures 44- of complementary outline to the inner end portion of the horn shell 37 so that the horn shells can be assembled'through the respective openings 44 from the inside of the crown'dll into snug engagement at their inner end portions with the edge defining the respective opening 44.

Retention of the respective horns 37 in their respective aperturesdlis accomplished by having the inner end portions of the side walls 42 provided with depend I ing' retainingo-r stop lug extensions 45 that are engageable asshoulders against the inner side of the margin defining the lower portion of the associated aperture 44. An upper innerend interlock lug extension 417 on the shell'37 provides an outwardly facing shoulder that engages retainingly withrthe upper margin defining the aperture 44. The crown 40 is provided with a shoulder '48 spaced radially inwardly from'the upper margin of the side wall' 41 and engageahle retainingly and-under resilient tension by the extremitytip-o-fthe' retaining extension 47.

Inassemblinglthe.horn37 with the capor cover, the horn is extended through the aperture 44 until the retaining and stop lugs 45 engage the lower margin of the side wall 41 and the end of the retaining lug extension 47 engages under the crown 4%) adjacent to the shoulder 48, substantially as shown in dash outline in Figure 6.

Then the born 37 is forced to fulcrum clockwise as seen in Figure 6 on the lower edge of the opening 44- to snap the retaining lug 47 forwardly and into retaining tensioned engagement with the shoulder 48. The horn 37 is thus effectively retained against inward displacement as Well as outward longitudinal displacement.

As the final assembly step, an integral lower marginal tongue extension 49 at the aperture 4 3 is bent up into bracing'relation to the side walls 4-2 of the horn 37 and into closing relationrto the opening 44.

In the modification of Figures 7 and 8, a cap or cover 50 is provided having a plurality of horn shells 51. The cap or cover 549 includes a sheet metal body stamped or pressed to form and including a sloping major wall "portion 52and a central outwardly projecting crown protrusion'53having a side wall '54-. The side wall has respective'apertures 55 therein through which the horns 51 project in assembly.

'Each' of the horns 51 is preferably formed up from a sheet metal blank B as seen in Figure 9 which is creased and bent along lines L as indicated in Figure 9 toprovide co-extensive'somewhatt'laterally and rearwardly fiaring side walls 57 merging at an outer blunt reduced width tip 58 and defining an inward opening.

At their 'inner end portions, the side walls 57 are provided with depending retaining lug extensions 59 as well as upwardly projecting respective similar lug extensions (it).

In assembly the downward lug extensions 59 provide respective shoulders engaging against the lower margin defining'the associated crown side wallopening 55 while the upper retaining extensions dtl'engage against the upper margin defining the aperture 55, after the respective shell horn 51 has been assembled by projecting the groove is feasiblewhere the material from which the same through the opening 55 into the assembled position. For retaining the shell horn 51 against inward displacement, the crown 53 is provided with shoulder means 61 which in the present instance is shown'as comprising an annular symmetrical shoulder pressed into the marginal portion of the crown top. This shoulder '61 may be preformed and the upper retaining lugs 6t? snapped into the groove 62 provided in the crown margin, or the shoulder 61 may be spun or pressed into the crown after assembly of the horns with the crown. However, by reason of the individual character of'the retaining lugs so and the converging relation thereof as best seen in Figure 1.0, snapping of the'same into a preformed retaining horns 51 is made is of adequate flexible resiliency. As best seen in Figure 8, the groove as may be substantially complementary to the contour of the retaining lug extensions 69, shown in this instance as formed on a radius. The manner in which the horns 51 may be assembled by snapping the retaining ears or lugs 60 into the groove 62 in the final assembly is indicated in dash outline in Figure 8.

As the final step in completing assembly of the horns 51 with the crown 53,- a side wall bracing and closure tongue flange 63 is bent up from the dash position as shown in Figure 8 to the full line position shown in'Figures 8 and 10. Thereby the side walls 57 are braced against inward collapsing and the opening at the inner end of the horn 51 is closed again'stentry of dirt into the crown;

I Although herein the horn members 17, 37 or 51, as the case may be, have been disclosed especially in conjunction with the crown protuberance of a respective cover oracap member, it will be understood that at least in certain aspects the construction disclosed and the method ofassembly can be employed to connect projecting shell-like members from other parts of a sheet metal member such as a Wheel cover or the like.

It will be understood that modifications and variations may be eifected without departing from the scope of the novel concepts of the present invention.
