PROCESS OF. PRODUCiNG BAG FRAMES.
Application filed April 3,
This invention relates to improvements in the art of producting sheet metal strips or blan {S as used in the construction of many articles, such, for instance, as bag frames.
One of the objects of the invention is to provide a novel process for the construction of such like parts whereby they can be produced in an extremely rapid and economical manner.
Another aim is in the provision of aprocess, comprising several steps, from the fiat sheet blank to a finished product ready for bending and assembly, and by which uniformity is attained.
Theseseveral objects and others of a similar nature, are secured by the novel and practical process hereafter described and lllust-rated in the annexed drawing, forming part hereof, and in which Figure 1 is a plan view of a portion of a sheet metal blank ready to have the first operation performed upon it.
Figure 2 is a similar View of the same, shown as having passed through a rolling process imparting stripes of a fanciful design by embossing means.
Figure 3 is another View of the strip, severed and shaped by stamping to produce required end formations, including perforations and prior to shearing into finished width.
Figure t is a plan View of the finished product, ready for further operations not part of this process.
In Figure 1 there is shown a fragment of a plain metal strip 10, as received either flat or from a coil, the same being indefinitely long and of such width as to furnish several of the finished blanks without waste.
This strip is passed through embossing rolls to produce stripes 11 of any preferred fanciful pattern, the same being so ar ranged that a pair of the stripes will appear properly on the finished article and it is to be noted that the embossing operation is performed simultaneously for all the stripes and throughout the entire length of the strip at one setting.
The next operation in carrying out the process is to feed the strip into a punch press or stamp wherein, at proper intervals, the hinge lugs 12 are formed at one operation on both of the severed ends of the strip, and simultaneously therewith the rivet openings 13 in the lugs together with 1924,; seri my 704,004.
The relatively short .blanks, uniform in length, width and contour are next sheared to produce the frame blank shown in Figure 1, the same having its stripes so arranged as to present a space therebetween and uniform margins at its edges.
Obviously there is no waste of material, except for the small punchings adjacent the lugs, and it will be apparent that the embossing is expeditiously performed and the time taken in producing the end profiles is materially less than if separate operation were performed at each end of a strip equal in width to the finished article. I
Although the foregoing is descriptive of the preferred embodiment of the invention,
it will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the scope of the claims hereto appended.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1.,The process of producing bag frame blanks which consists in subjecting an indefinitely long stripof sheet metal to a punch press, whereby a series of frame end members are produced in opposed relation, perforating the frame end members and adjacent portions of the blank simultaneously to forming hinge lugs and shearing the strip lengthwise to produce separate bag frame blanks.
2. The process of producing bag frame blanks which consists in passing an indefinitely long strip of sheet metal between embossing rolls, whereby spaced stripes are formed, subjecting the embossed strip to a punch press whereby a series of frame end members are produced in opposed relation, perforating the frame end members and adjacent portions of the blanks simultaneously to forming the lugs, and shearing the strips lengthwise to produce bag frame blanks, each blank having two stripes symmetrically disposed, said frame end menu bers constituting hinge lugs. I
3. The process of producing bag frame blanks which consists in passing an indefinitely long strip of sheet metal bet-ween rolls, subjecting the strip to a punch .press whereby a series of frame end members are produced in opposed relation, perforating the frame end members and adjacent portions of the blanks simultaneously to forming the lugs, and shearing the strips length- Wise to produce bag frame blanks, said frame end members constituting hinge lugs.
l. Flat blanks for hag frames produced by ornamenting an-indefinitely long strip of material by the production of grouped pairs of stripes lengthwise thereon, piercing the material to produce a plurality of 1 uniform opposed ends constituting hinge lugs simultaneously perforating the strip adjacent the lugs and shearing the strip to produce independent frame blanks.
This specification signed and witnessed 15 this 28th day of March, 1924:.
