PICTURE FRAME.

Specification of I etterslatent.

Application filed April 20, 1921. Serial No. 462,826.

useful Picture Frame, of which the following is a specification.

My invention relates to an improved picture frame for so-called medallion photographs and the like. The object is to provide a construction which may be economically produced, the finished article being very easy of application or removal.

In the drawings:

Fig. 1 is a front elevation of a medallion with the frame applied.

Fig. 2 is an edge elevation of a portion of the medallion with a section of the frame in place.

Fig. 3 is a perspective view of a portion of the stock from which the frame is made.

Fig. 4 is an end elevation 0fv said stock after the first operation.

Fig. 5 is'a perspective view showing the effect of bending the stock shown in Fig.

'4: into circular form.

1 represents a medallion, which in this particular instance is oval in form, the edge being rounded. While the particular construction of the medallion is immaterial to this invention, it will be understood that such devices are usually in the form of a plaque with a convex front surface and a concave rear surface. lhe frame to which my invention relates is made of a size to fit snugly upon the circumferential edge of the medallion. The front edge 2 ofv the frame is notched or serrated for the purposes hereinafter described. The rear edge 3 of the frame is unbroken. I make the frame by taking a flat strip of metal, one edge of which is notched or serrated, to provide the desired ornamentation as well as to slightly weaken the extreme edge of the same, so that when the strip is transformed into the final shape of the frame, the outer edge will not tear. I first take this fiat straight strip as shown in Fig. 3, and I then bend down the unbroken edge at substantially right angles as shown in Fig. 4. I then bend the strip into round or oval form and bring the ends together and solder them. The bending of the strip into round or oval form produces a twist in the same throughout its entire length so that the inner edge of the frame presents a groove or channel which will receive the rounded edge of the medallion. The circumference of the, unbroken rear edge of the frame is slightly less than the circumference of the medallion, with the result that it-is necessary to apply if Patented May 9,1922.

a little force in fitting the frame to the medallion, but'this may be easily done since the rounded edge of the medallion permits the rear unbroken edge of the frame to be easily snapped thereover by finger pressure alone. When this is done, the framewill he held friction-tight in place, the ornamental serrated front edge of the frame furnishingan artistic frame or finishing for the edge of the medallion as well as serving to prevent accidental disengagement therefrom. If desired, one or more decorative scrolls or tips 4 may be secured to the outer edge of the frame, but I wish it to be understood that my invention is not limited to the application of such decorative additions. In the foregoing, it will be seenthat the serrated edge of the frame performs a double function, to wit, it provides the decorative meansaforesaid, and it weakens that edge of the frame so that when the straight strip of right angular cross-section is bent into curved form, the

said weakened edge of the frame will stretch so as to permit of the twisting or, distortion of the strip throughout its length to produce .the inner channel adapted to receive the rounded edge of the medallion. It will be observed "that the serrations shown terminate short of the bottom of the channel. may be rapidly and economically produced,

By my invention, such frames since it is possible to stamp out cheaply and rapidly the initial flat strip with one ornamental edge. The processof bending down the unbroken edge is exceedingly simple, and the final process of bending the angulair strip into round or oval form'and cut-' ting off and soldering the butt ends may to furnish a frame of an exceedingly at-" tractive appearance which may be easily and quickly applied to the medallion withwithout the employment of any additional clips or fastenings suchas are us'ually emarticles of merchandise. I

From the foregoing it Wlll be seen that my invention relates not only to the finished Y also be quickly accomplished, and all at a I very small expense, whereby it is possible out the exercise of any special skill, and

prising, first forming a straight flat strip with one serrated edge, then bending the strip longitudinally at substantially right angles, then bending the strip transversely into curved form, simultaneously twisting 15 said strip to form a channel at the inner side, and then uniting the ends of the strip to form an endless "frame of curved contour.
