PROCESS OF FORMING BAG-FRAMES.

To all whom it may concern:

and ALBERT FULLER, citizens of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented a certain new and useful Process of Forming Bag-Frames, of which the following is a full, clear, and exact description, such as will enable others skilled: in the art to which it pertains to make, con-;

ing more rigidity and stability than those The primary object of this invention isv the production of angular bag frames for struct, and use the same.

bags and purses, and especially for traveling chatelaine and similar bags by a process which consists in first cutting a blank of the requisite form from sheet metal, said blank comprising a main body member and angular pivot members, then, by means of suitable punches and dies, angling the major portion, or the entirety of the main body member, and finally angling the hinge members to form the completed member with sharp corners, or first angling the major portion of the main body member, thereafter angling the corner of the blank and finally angling the hinge members to form the completed member with sharp corners,

or first angling the major portion of the main body, corner and one hinge member, and thereafter angling the remaining portion of the main body member, other corner and hinge member to form the completed member with sharp corners.

Hitherto, in the construction of bag.

frames of the type to which our invention relates, it has been customary to form at first a blank as illustrated in full lines in} Figure 6, and thereafter by suitable drawingdies, simultaneously draw up the metal around the three edges of the blank, and thereafter, cutting out the blank on the dotted lines indicated in said fi re. This process is objectionable for the reason that while it lends itself admirably to soft metal, it is not at all adapted when it is desired to use what is known in the trade as quarter, half or hard metal, and for the further reason that the metal indicated by the dotted lines is waste material.

With our improved process, it is not necessary to cut a blank of the outline indicated in Fig. 6 having a solidcenter, but one which has the dimensions and" outlines indi Specification of Letters Patent.

In describing the process forming a part of our invention, we will simultaneously describe the productof the same, so that those skilled in the art to which it pertains, may gain a full knowledge of the process as well as the product.

In Figs. 1 and 7, we hiWQ shown the sheet metal blanks a and a as they are punched out. Since the blanks form three sides of a hollow rectangle, the resulting waste is reduced to a minimum, and may be further reduced by alternating the blanks as illustrated in Fig. 1. The blanks (a comprise a main body portion 5 and the two hinge portions 0 at right angles thereto. To complete the frame members with sharp corners, the outer edge portion of the blank is bent up or angled along the dotted lines of Fig. 1, so that a cross section is, as shown in Figs. 5, 13 and 14, where A represents an angled frame made from the blank a and A one made from the blank a of Fig. 7. It will be seen that the main body portion Z) of the blank a. is made wider than the hinge portions 0, thereby producing in the completed frame member A a flangeextending beyond the plane of the edges of the angled hinge members as clearly shown in Figs. 13

and '14. As shown, these sheet metal blanks a are blanked out in such a way as to nearly resemble the finished frame member, which as previously stated, comprises the main body' member 6, and the two angular hinge members 0, as distinguished from the blank illustrated in full lines in Fig. 6, in which it was necessary to cut out a blank as shown, and then by means of a simple drawing die, angle or draw up at one operation, the main body member and the rectangular hinge members, and thereafter cutting out the blank on the dotted lines indicated in said figure, said portion indicated by the dotted lines representing the waste material. The

process just described in'connection with the blank illustrated in Fig. 6 of the drawings, did lend itself admirably to the heretofore soft material used, but is absolutely impractical when applied to what is known in the trade as hard material, for the reason that in the subsequent operation of drawing up or angling the sides of said blank, the metal at the angled portion of the blank would break, owing to the hardness of the same. WVe have also found it to be impracticalto take a blank as indicated in Figs. 1 and 7 of the drawings of either soft or hard material, and subject it to the operationof simultaneously angling or drawing up by.

means of a drawing die, the main body member'and hinge members of said blank,

'forfthe reason" that the metal" of the main bedyeembemhf body member, as indicated in Figs. 2, 8 and 10, and finally angling the hinge members and corners of said blank to form the completed member with sharp corners, as illustrated in Figs. 4; and'12.

Sometimes, we find it convenient to first angle the major portion of the main body member, as indicated in Fig. 8, thereafter angling the corner of the blank as indicated in Fig. 9, and finally angling the hinge members to form the completed member with sharp corners, as indicated in Fig. 12.

By the process described in connection with the blank in Fig. 7, we are enabled to produce a bag frame member, the main body portion In of which has formed thereon an angle or flange of greater depth than those of the hinge members 0 as illustrated in Figs. 13, 14, 15 and 16, in which the angled portion extends over and overlaps the angled portion of the other frame member, (see Fig. 13) thereby producing when assembled a bag frame of extremely neat appearance and novel construction.

A novel product of this process is further illustrated in Figs. 15 and 16, in which three members constitute the completed bag frame, two of which, namely, the outer ones A A are provided at the main body por tion with an angle or flange of greater depth than those of the hinge members, the space between the hinge members permitting the interposition of an auxiliary member A the wider angled portions of the main frame members A? cover the top of the auxiliary frame and the hinge members of said auxiliary frame filling in the space between the two outer frame members, which, when so assembled, produce an even surface extending entirely around the frame sections.

Another novel product of this process is illustrated in Figs. 17 and 18, which shows the form of inlay used in connection with the above described bag frame members. It will be seen that the inlay B is angled in the same manner as the frame member--A shown in Fig. 4, except that the angled portion is only deep'enough' to accommodate the thickness of the leather which isto'be inserted between the inlay and" the bag 'membenandthereaft rheld in place ts thr' gh the inlay anctframe meniual manner: The manner of the tools and the product, inasmuch as this process of independently angling the sides of the blank, as distinguished from angling or drawing up the sides of the blank simultaneously as heretofore done, .enables us to dispense with an accurately fitting punch and die, the dimensions of which have to be kept up to asize to accommodate material of a given thickness and substitute therefor a punch and die of very simple construction, which can be set up with relation to each other to accommodate the material of varying thicknesses.
