Nov. 3, 1959 N. LOCKRIDGE SUPPORT Filed Oct. '7, 1957 United States Patent 9 2,910,794 SUPPORT Nanelia Lockrid ge, Chicago, Ill. Application October 7, 1957, Serial No. 688,678 i i i s clams. (or. 41-10 My invention relates to ornamentation in the nature of an edging of a type appropriate to many articles. One of its common uses is in connection with table doilies on which dishes and food may be set at dinner.

In the accompanying drawings:

Figure 5 is a diagram of the corresponding edge contour when the rosettes are more closely spaced;

Figure 6 is a diagram of the same edge contour when the rosettes are more widely spaced;

Figure 7 is a diagram of one of the attractive contours that can be produced by a shift of the tension attachments; and

Figure 8 is a detail of the apex of one rosette.

In the embodiment selected to illustrate the invention, the main doily 10 may be rectangular, circular, or elliptical. In one of the commonest embodiments, it is manufactured by die cutting the lace-like pattern from a thin sheet of flexible plastic. The individual blanks 12, from which the rosettes are formed, are circular. In Figure 3, a small central portion of the lace-work is illustrated, including a small central opening at 14.

Such a flexible sheet is first bent double, and the points indicated as B and B are attached to each other, as by a tiny wire clip or by adhesive or by warming thermoplastic material to form a local weld. The next step is to attach the points L and L by bending the edge be tween them up to define a lobe 16 (see Figures 4 and 5). This completes the formation of one of unitary rosettes 18. A series of such rosettes are affixed to the main doily 10 along lines spaced inward from the edge of the main doily, so that the apex of each rosette overlies the edge of the main doily to the extent of about one fourth or one third of the axial dimension of the rosette. Subsequently, the adjacent outer portions of each rosette are attached to the adjacent rosettes at points T and T The resulting configuration of the large end of the rosette illustrated in Figure 4 is that which results when the spacing of the rosettes along the edge of the main doily is approximately equal to the undistorted maximum horizontal dimension of an individual rosette. In this instance, the attachment at T and T as indicated in Figure 4, makes no material change in the contour of the large end of the rosette.

By reducing the spacing of the rosettes to about 60% of that obtaining in Figure 4, the rosettes are caused to press against each other, and the higher configuration illustrated in Figure 5 results. By increasing the spacing of the rosettes, the attachment between the rosettes will elongate the large ends horizontally and reduce their vertical dimension ure 6.

2,910,794 Patented Nov. 3, 1959 ice to secure an appearance according to Fig- Finally, by positioning the attachment points T, T considerably closer to the point B and reducing the spacingof the rosettes correspondingly, the tension at the attachm ent points T ,T can pull the edgeportion between them relatively straight, and above the attachment points the abutting sides of the rosette will rise substantially vertically to produce the ornamental appearance of Figure7.

Because of the central hole 14, the completed individual rosettewill not have a sharp apex, but the folded circle will assume a U-shap'e, as illustrated in Figure 8.

It willibe obvious that only a few of the wide variety of ornamental configurations that can be produced according to the'invention' have been illustrated in the drawings. In general, identifying'the'arrangement with respect to Figure 3, the angle L CL can be varied about 70 to and the same variation can be obtained in the angle T CT but the two angles 'need not necessarily be equal. For instance, the configuration of Figure 7 results from a substantial reduction of the angle T CT leaving the angle L CL substantially unchanged.

In allembodirnentsfthe finished product has a central supporting area surrounded by an attractive ruching, or frill. With the rosettes made up from thing flexible plastic sheet, die cut to a lace-like pattern, the process of fabrication and assembly is extremely simple, and the assembled article very attractive. The plastic product, according to the invention, can be made of any of a wide variety of colors and color patterns with minimum expense and labor. In the hands of the user, if it happens to be soiled with food, even very badly soiled, a dousing in soapy water and hanging up to dry restores it completely to its original freshness and beauty.

It will be apparent that because the folds are made through the center of the circle, the finished rosette will present a generally conical shape with its apex at the center of the sheet. When the rosette blank is circular, the base of the cone will have all the edge of the sheet lying substantially at the surface of a sphere, and the center of the sphere will coincide with the center of the sheet. It will be obvious that blanks deviating from a circular outer contour can produce attractive variations from the spherical shape, including a cone with a plane base.

By the use of rosettes and main body members of assorted colors in various sequences, a wide variety of color combinations and patterns can be produced.

Others may readily adapt the invention for use under various conditions of service by employing one or more or the novel features disclosed, or equivalents thereof. As at present advised, with respect to the apparent scope of my invention, I desire to claim the following subject matter:

1. An ornamental rosette comprising an initially flat, circular, piece of sheet plastic, extensively cut open inside its periphery to leave a lace-like remainder; said sheet being first folded by attaching diametrically opposite peripheral points to each other by a first fastening, to bring the entire peripheral edge into an approximately figure 8 configuration having opposite reentrant sides adjacent the point of fastening; the equal lobes of said figure eight being subsequently flexed about said first fastening point, to straighten out one of said sides and increase the concavity of the other side until the edge portions on either ide of said concavity meet; said meeting sides being then fastened to each other by a second fastening; whereby the entirety assumes the form of three cones having all their apexes at the original center of the sheet; the end cones being approximately equal and larger than the middle cone.

2. An ornamental rosette comprising an initially flat,

ripheral points to each other by a first fastening, to bring the entire peripheral edge into an approximately figure 8 configuration having opposite reentrant sides adjacent the point of fastening; the equal lobes of said figure 8 being subsequently flexed about said first fastening point, to straighten out one of said reentrant sides, and increase the concavity of the other side until the edge portions on either side of said concavity meet; said meeting sides being then fastened to each other by a second fastening; whereby the entirety assumes the form of three cones having all their apexes at the original center of the sheet; the end cones being approximately equal and larger than the middle cone; the base of the middle cone having a symmetrical tear-drop configuration with its apex at said second fastening and remote from said first fastening; the base of each end cone having a tear-drop configuration with its apex at said first fastening; the entirety of the periphery of the base of said middle cone being constituted of portions of the peripheries of said end cones; the tear-drop configurations of said end cones being asymmetrical, with the points curved in toward each other around the lobe of said middle cone.

3. An ornamental rosette comprising an initially flat, circular piece of sheet plastic; said sheet being first folded by attaching diametrically opposite peripheral points to each other by a first fastening, to bring the entire peripheral edge into an approximately figure 8 configuration having opposite reentrant sides adjacent the point of fastening; the equal lobes of said figure 8 being subsequently flexed about said first fastening point, to straighten out one of said reentrant sides, and increase the concavity of the other side until the edge portions on either side of said concavity meet; said meeting sides being then fastened ito each other by a second fastening; whereby the entirety assumes the form of three cones having all their apexes at the original center of the sheet; the end cones being approximately equal and larger than the middle cone.
