w. HIERI'NG METHOD OF AND BLANK FOR MAKING CHANNELED BAG FRAMES Filed Jul .1; 193a ATTORNEY Patented July 6, 1937 UNITED STATES PATENT OFFICE METHOD OF AND BLANK FOR MAKING CHANNELED BAG FRAMES William 0. Hiering, Newark, N. J., assignor to The J. E Mergott Company, Newark, N. J., a corporation of Delaware I Application July 1, 1936, Serial No. 88,346, 4 Claims. (cl. 113--116) This invention relates to frames for hand bags, and more particularly to a method of making said frames.

Hand bag frames are generally U-shaped, and

in order to prevent buckling anddistortionat the comers, heretofore, considerable care has been necessary in the bending of the frame. In U. S. Patent No. 1,925,804 granted to me on September 5, 1933, there is described a method of making a frame whereby neat, sharp and solid corners are produced which are free from open joints, with no puckering of the metal. That patent applies especially to a channeled frame member opening upwardly. It is an object of the present invention to provide a method ofmaking a hand bag frame which is substantially tubular, having a. lateral opening. In accordance with the invention, a blank is provided from which the frame is formed. 20 This blank has cut therein triangular openings and trapezoidal notches in the edge of the blank adjacent the triangular openings. From this blank there is formed a substantially tubular member which is bent into a U-shaped frame hand bag frame from a single sheet of bendable metal, without resorting to spot welding or rivet- 40 ing or the attaching of an additional piece of metal to the frame member at the corners thereof. e

A further object is the provision of a novel blank for forming a tubular frame member, which 5 blank consists of a single strip of material provided with openings and notches therein to enable it to be bent to provide neat angled corners.

These and other advantageous objects, which will later appear, are accomplished by the simple 50 and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which:

Fig. 1 is a perspective view of a frame member 55 embodying my invention,

member, the openings and notches enabling the Fig. 2 is a perspective view of a blank from which the frame member is formed,

Fig. 3 is a plan view of a portion of the tubular member, showing a step in the formation of the frame member,

Figs. 4 and 5 show further steps in the formin of a corner of a U-shaped frame member,

Fig. 6 shows a comer of a. frame member formed in'accordance with myinvention, and

Fig. .7 isa view showing the obverssideof the corner shown in Fig. 6. I

Referring to the drawing, in Fig. 2 there is shown a metal strip 8 from which the frame members are formed. The strip is provided with triangular openings 9, and adiacent each opening 9 the edge of the strip is provided with trapezoidal notches I0, thus forming connecting strip ll between the openings 9 and the notches HI. After providing the strip 8 with ;the openings 9 and notches III, the strip is then bent into a substantially tubular shape as indicated in Fig. 3, having the edges l2 and I3 spaced from each other on the same side of the tubular member. The tubular member is then bent into a U-shape, each corner being formed as shown in Figs. 4 and 5, the connecting strip ll being doubled back upon itself as indicated in Fig. 5 and the corners thus produced have the appearance shown in Fig. 6.

By means of this method, I am able to produce neat right-angled corners in a substantially tubular U-shaped hand bag frame member, without cracking or buckling of the metal at the corners during the bending process.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive 'or limitative of the invention, of which obviously an embodiment may be constructed including many modifications, without departing from the general scope herein indicated and denoted in the appended claims.

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

1. The method of making a substantially tubular bag frame member having an angledcorner from a flat metal strip, comprising providing the strip with a triangular opening and a trapezoidal notch in the edge of the strip adjacent said opening forming a. connecting strip between the opening and the notch, then bending the strip into a substantially tubular shape so that the connecting strip forms a part of a wall of the mem-; .ber, then bending the tubular member so that the connecting strip will be doubled back upon itself to produce a right angled corner.

jacent said notch providing a connecting strip be-.

tween the opening and the notch, the bases of said opening and notch being adJacent each other.

4. The method 01 making a cylindrical tubular U-shaped bag frame member having right angular comers, comprising forming trapezoidal notches in the longitudinal edge of a strip otbendable sheet material, forming a triangular opening in said strip adjacent each notch to providea connecting strip, bending the strip into a substantially cylindrical tubular shape, and then bending the tubular shaped strip so that the connecting strips will be bent back upon themselves and the triangular openings will be closed toprovide angled corners.
