PROCESS FOR MAKING BAG-FRAMES.

' Application filed April 16,

To all whom it may concern:

Be it known that I, 'FRANZ A. FULLER, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Process for Making Bag- Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has reference to improvements in the manufacture of frames for bags and purses, especially for traveling, chatelaine and similar bags.

The object of my invention is to overcome present difliculties, dispensing with the numerous constructions heretofore employed for connecting the pivot members with the main body of the frame section, in order to produce a bag frame with sharp angular corners, by making a frame from one piece of material, thereby producing a neat, sharp, and solid corner angle, free from open joints and one in which the cracking or puckering of the metal at the corners ofthe frame during the process of the manufacture of the same, is entirely overcome.

In the accompanying drawings forming a part of this specification,

Figure 1 represents the blank which subsequently forms the bag frame member, pre paratory to channeling the member and making the bend to form the corner.

Fig. 2 illustrates the blank after being channeled and the method of bending the channeled blank member to form the corner.

Fig. 3 represents a plan View of the same.

Fig. 4 represents a front elevation of a bag frame.

Fig. 5 represents a cross-section of the same; and

Fig. 6 represents a fragmentary view of a portion of the angled blank, illustrating in dotted lines the bend that is given to a portion of the hinge member 9, and a por tion of the main body member h, adjacent to the cusp e and notch 7.

Similar letters of reference refer to like parts throughout the specification and draw ings.

In describing the process forming my in Specification of Letters Patent.

vention, I will simultaneously describe the product of the same, so that those skilled in the art to which it pertains, may gain a full knowledge of the product, as. well as of the process.

In Fig. 1, I have shown a sheet metal blank a as it is punched out. The blank a comprises a main body portion provided at its extremities with apertured ears 6, and along its sides, intermediate of its ends, with diametrically-oppositely arranged projections 0, which subsequently form the corners of the bag frame, as clearly indicated in Fig. 4f of the drawings. To complete the frame members dcZ, with the corner illustrated in the drawings, the blank a is first placed in a suitable die, and the central portions of the blank a are channeled along the dotted lines, as shown in Fig. 1, so that a cross-section is as shown in Fig. 5, and a side elevation is as shown in Fig. 2.

It will be seen from an inspection of F ig. 2, that the blank when channeled as described, is also simultaneously formed with the cusps e-e on the lower side, and the depressions or notches f-f on the opposite or top side. After the blank a is channeled and provided with the cusps e and notches f, as heretofore described, the hinge members 9 are bent. The hinge members g g and a portion of the main body member 71. of the blank are bent at right-angles to the main body member h, as illustrated in Fig. 2.

The cusps e-c will be found to contain a sufiicient amount of material to stretch around the angle of the bend without weakening the same, to form a corner as illustrated, which is so much to be desired in bag frames of the character to which my bag frame relates. At the same time, the notches f upon the opposite outer side of the blank are of such shape and dimensions so as not to pucker or form ridges during the process just described. If it is attempted to bend a straight piece of metal such as bag frames are usually made from, it will be found that the inner corner will be puckered and covered with ridges, While the outer edge. will have been found to stretch to such an extent as to appear ragged and present a cracked and unsightly appearance.

By the process just described, I am enabled to produce a bag frame member which is composed of a single piece of metal, without the usual open joints and angled connections, and yet, by the exercise of this process, I am enabled to produce this frame with a minimum of waste material, and at the same-time, preserve maximum strength at the hitherto weakened points in the frame.

Having thus described my invention, what I desire to claim and secure by Letters Patent is V The process of forming channeled sheet metal bag frames, consisting in forming" a flat sheet metal blank provided with diametrically-oppositely arranged projections extending from the edges of said blank and near the ends thereof, channeling the central portion of said blank longitudinally and simultaneously forming notches projecting inwardly from the upper wall of said channeled portion of the blank and cusps adjacent said notches projecting dowmmrdly from the edges of the said Walls of the Cl12l11' neled portions of the blank and bending the ends of the channeled member to form a completed member with double rounded corners.

This specification signed and witnessed this 9th day of April, 1917 FRANZ A. FULLER. lVitnesses FREDK C. FIsoHER,
