This invention relates to a method of making metallic frames and has for its object the provision of an improved method whereby metallic frames, such as picture frames or the like may be rapidly, economically, and efficiently produced through the employment of a sequence or series of operative steps, comprising a method having many advantageous features over methods heretofore followed. A more specific object of the invention is the employment of a method for the production of a frame comprising front and rear confining flanges and formed from one continuous strip of metal rather than from a plurality of independent metallic members.

Other objects will appear hereinafter. The invention consists in the combinations of the successive steps oroperations hereinafter described. and claimed, although it is to be understood that the method is not to be literally confined to the sequence stated.

' The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in f which:

Fig. 1 is a plan vievw of a metallic blank strip from which the frame is formed; Fig. 2 is a plan view of the strip after the front and rear confining flanges have been bent to form 0 a channel shaped strip; Fig. 3 is asideview of the flanged portion ultimately forming the front confining flange of the frame after the corner miters have been cut; Fig. 4; is a view similar to Fig. 3 but taken on the opposite side .to show the rear confining flanges; Fig. 5 is a front View of the completed frame bent to shape before attachment of the miter concealing members; Fig. 6 is a rear view of the frame shown in Fig. 5; is a sectional view taken on the line 7-7 of Fig. 5 Fig. 8 is a sectional View taken on the line 8-8 of Fig.4); Fig 9 is a view taken on the line 99 of Fig. 4.; 'Fig. 10 is a detail section of a corner forming portion of the strip after the miter. out has been made; Fig. 11 is a perspective view of the completed frame with a pictureand backing incorporated; Fig. 12 is a vertical sectional view taken on the line 12-12 of Fig. 11; Fig. 13 is a detail view of one corner of the completed frame; and.

1 1 is a. detail sectional view taken substantially on the line 14-44 of Fig. 13.

As illustrated in the drawings, the preferredmethod of theinvention contemplates the initial selection of a strip of metal as tion 18 of the intended completed frame. It

will be understood that any suitable metal or material may be employed for the purpose, the essential requisites being that. suflicient flexibility or pliability is present to permit of the folding and bending operations next described.

The next following step in the preferred sequence is to bend the'continuous front and rear flanges 16 and 17, respectively, whereby the strip assumes the formation shown in Fig. 2, and in this operation the flange portion 16 may be formed of greater width than the rear flange 17. Dies may be employed for these-bending operations by which an embossed ornamental design such as shown in Figs. 11 and 13 will be formed on the flange .portion 16, by the employment of compley mentary embossing dies to produce anydesired designer configuration. For a rectanular frame, the channel member thus formed is subjected to three intermediate transverse miteringicuts 19, 20, and 21, as well as end mitering cuts 22 and 23, as shown in Fig. 3,

which may be performed by suitable miter- .ing dies, and in this operation the .cutting implements are-preferably disposed or used at the points 19, 20 and 21 to score to'a slight depth the inner surface of the portion 18, as shown in Fig. 10, to facilitate bending as presently described. At thisstage the in-, tegral member is composed of four sections represented by a to ront flange 24 for the completed frame,si e front flanges 25 and 26,

tended for the bottom of the frame.

- is severed for substantially one-half its width, as shown in Fig. 7, and the rear flange of this section is likewise severed and omitted.

Following the above described operations the sections are bent to form a rectangular frame as shown in Figs. 5 and 6, the scoring described facilitating the bending operations,

. and the free ends 21 and 23 may be soldered steps for carrying my. invention into effect,

across the edge'portion- 18 and the excess solder later ground down to form a smooth corner and complete the continuity of the frame.

To complete the frame proper the final operation consists in concealing the miter cuts at the corners at the respective meeting edges of the front flange portions, and this is preferably accomplished by the use of relatively narrow ornamental members 32 of the necessary length to entirely conceal the cut edges as shown in Fig. 13; These. members are preferably secured in place by aspot welding operation which serves to unify the adjacent portions as shown at 33 in Fig. 14. This operation rigidly secures the adjacent edge portions of the mitered-flanges to the concealing member and thus serves also to strengthen and render the frame more rigid.

The assembly shown in Figs. 11 and 12 is completed by inserting through the slot 31.

a glass 34, picture 35, intermediate filler 36, and backer 37, to which may be secured a supportingl member 38.

By t a frame is produced possessing general \attractiven'ess and the appearance of superior workmanship. I I

While I have illustrated and described the preferred sequence and series of operative this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the method set forth, but desire to avail myselfof such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The methodof making metallic frames which comprises longitudinally bending a strip of metal to form a continuous edge portion and a front flange ortion and a rear flange portion, cutting miters in said flange portions, bending said strip at the mitered corners, soldering the free ends of said edge portion, and spot welding a piece of concealing metal at each corner over the mitered cuts on the front flange portion.

2. The method of making metallic frames which comprises longitudinally bending a strip of metal to form a continuous edge portion and a front flange portion and a rear flange portion, cutting miters in said flange portions, simultaneously scoring said edge portion at the points of the miter cuts, bending said strip at the mitered corners, soldering the free ends of said edge portion, and

spot welding a piece of concealing metal at each corner over the mitered cuts on the front flange portion.

3. The method of makin metallic frames which comprises longitudinally bending a strip of metal to form a continuous edge por- I e employment of the present method
