BAG-FRAME.

Specification of Letters Patent.

Patented July 2, 1912.

' scription 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 difficulties in dispensing with the numerous simple means 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 pieceof material, thereby producing a neat, sharp and solid corner angle, free from open joints, and one in which the crackin or puckering of the metal at the corners o the 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 illustrates the blank which subsequently forms the bag frame member, pre aratory to chan-.

neling the member and ma ing the bend to form the square corner. Fig. 2 illustrates the blank after b ng channeled and the method of bending the channeled blank member to form the square corner. Fig. 3

represents a plan View of the same. Fig.4 illustrates a front elevation of a bag frame; and Fig. 5 is a cross-section of the same.

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

In describing the process forming apart of my, invention, 1- 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 process, as well as of the product.

In Fig. 1, I have shown a sheet metal from, it will be blank a as it is punched out. The blank a I comprises a main body portion provided at its extremities with ears I). To complete the frame members a, c with sharp corners, thebTank a is first placed in a suitable die and the central portions of the blank a are channeled along the dotted lines of Fig. 1, so that a cross-section is, asshown in Fig. 5, and a side elevation is, as shown in Fig. 2. It will be seen from an inspection of Fig. 2, that the blank when channeled as described is also simultaneously formed with the cusps d, d on the upper side and the notches e, e on the opposlte or under side. After the blank a is channeled, and provided with the cusps and notches, as heretofore described, the hinge members f, f are bent at right angles to the main body member f, as illustrated in Fig. 2. The cusps d, d will be found to contain a sufficient amount of material to stretch around the angle of the bend without weakening the same, and form a sharp and square corner 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 6 upon the opposite underside 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 tobend a straight piece of material, such as ba frames are usually made found that the inner corner will be puckeredand covered with ridges, while ,the outer edge will be found to have stretched to such an extent as to a pear ragged and present a cracked and unslghtly appearance.

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

I claim:

'1. A blank for forming bag frames comprising a straight channeled strip of sheet metal U-shaped in cross section, the side walls of saidstrip being continuous from end to end of the blank, the outer wall of said channeled strip being provided with outwardly projecting cusps and the edges of the side walls of said channeled strip being provided with, notches therein adjacent said cusps. I i

2. A blank for formingv bag frames comprising a straight ehanneled strip of sheet metal Ushaped in cross section, having con tinuons 'nnbrokenside walls extending from end to end of the blank, the outer wall of said channe'led' strip be ng provided with outwardly projecting cuspsand' the edges of the side walls of said channeled strip being provided with ll-shaped notches; therein} adjacent the cusps, thedistance between the apic'esof said notches and the outer wall of theadjacent ens s being substantially equal 15 to the width of t e sidewall of the blanks. This specification signed and witnessed this 6th dayof May, 1910.
