This invention relatesto a machine for making frame parts for handbags and has for its primary object and purpose to pro vide certain improvementsin a machine of thiitgellelal type as disclosed in Patent No. 63, wedto me on the 5th day of Jannary, 1926, whereby such bag. frame parts a predetermined crosssectional form may be expeditiously produced with amater al improvement of the finished product.

In the machine shown in my issued patent,

1 the stock is first acted upon by means of snitable dies to produce at spaced points in the length thereofintegrally connected perforated ears by-means ofwhich assembled coniplementary frame members may be hingedly connected with each other. Thereafter the material is cut on a transverse line between theears and the separated sections are successively bent into the desired cross sectional shape. This cutting of the sheet metal material between the connected ears, results in a rough or unfinished edge on the ear ofieach irame part, which it is desirable to eliminate.

ft is therefore, one oftheimportant objects of my present improvementsto provide a machine for forming the. frameparts from sheet metal strip stockwvhereby this disadvantage is overcome and a perfectly finished product is produced;

It is alsoa further object of the invention to provide novel automatically acting means whereby the sheet metal frame parts are bent to provide an intermediate longitudinally gitudinal flanges extending to the walls of said groove in. obtuse angular relation to each other. I

With the above and other objects in view, the invention consists in the improved machine ior forming bag frame parts and fin thejform i constructionand relative arrann'ement its several elements will be hereinaiter more frilly described illustrated in the accompanying drawings, and subsequent- 1vincorporated inthe suhjoined claims.

Referringwin detail tothe drawing, bag f-rameparts are formedjfrom', sheet metal strip stock indicated at 5 in Figs, 1 and'Qof the drawingsvvhioh is of the required thick ness so that it may be readily bent and shaped to the desired predetermined form.

In the first operation, the sheet metal. strip 5 is providedjalong one of its longitudinal edges with a continuous slightly inclined flange 6. This flanged strip is adapted to be fed over a suitable bed plate indicated at 7 having guiding means for the strip and above which a vertically movable die operates (not shown). This die, which produces at intervals in the length of the sheet metal strip the longitudinally spaced ears as shown at 8 is of slightly different form from that shown in my issued patent so that instead of providing the ears integrally connected with each other by a part of the stock, these. cars have no direct connection and are completely separated at their opposed ends, the parts of the sheet metal strip at opposite sides of the ears do however, remain integrally joined at one side of the ears 8 by the narrow longitudinally extending connecting portion 9. Each of the ears 8 is of course, perforated as at 10 to receive the usual hinge pin when assembled complementary frame members are connected with each other.

After the metal strip has been provided with the ears 8 and connecting portion 9, it is fed over a table 11 having suitable guiding means and upon a supporting flange 13 of an anvil 12, the length of which is substantially equivalent to the length of one of the frame parts. This anvil is pivotally mounted for vertical movement as shown at 1 1 upon a suitable support 15 transversely spaced from the table 11 and is yieldingly urged upwardly by means of the springs 16 into engagement with the stop rod 17 This anvil is provided with a longitudinally extending flange 18 projecting upwardly above the supporting flange 13 upon which one edge portion of the metal frame strip is received.

Above the table 11 and the anvil 12, there is arranged a vertically movable plunger 19 which carries a die plate 20 having a lower edge portion 21 of the proper cross sectional shape for bending the frame parts into the form shown in Figs. 6 and 7 of the drawings. Any suitable means may be prrwided for moving this plunger downwardly against the action of the springs indicated at 29 which normally hold the die plunger in a raised position. The plunger 19 also carries a part- 23 having a beveled surface 24 to cooperate with a correspondingly beveled surface 27 on the upstanding flange 26 provided upon one edge of the plate which is slidably mounted in suitable guide ways on the under side of the table 11. At its other edge this transversely slidable plate may be provided with suitable supporting legs 28 resting on a base 25). Coiled springs 22 normally hold plate in the position shown in Fig. 10 of the drawings, and in spaced relation to the anvil 12 and its support 15. 7

At the right hand end of the plunger 19, a vertically movable member 31 is suitably pivoted at one of its ends as at 32. the other end of said member being provided with :1

downwardly extending finger 33 and being yieldingly held by means of the leaf spring 3 1 in contact with a stop 35. lVith this latter end of the men'iber 31 a projecting part on the manually operated plate 36 which is pivotally supported intermediate of its ends as at 37 is engaged. By depressing the other end of this plate, the end of the member 31 having the part 33 may be lifted against the action of: spring 3-1 to the dotted line position as shown in Fig. 14; of the drawings. This displacement of the part 31 is made with each feeding movement of the sheet metal strip so as to position the spaced ears 8 and the connecting portion 9 of said strip with respect to a vertically movable cutting member 38 which may be mounted upon the right hand end of the plunger member 19 so as to operate with the die plate 20.

Assuming that the section of the metal strip which has previously been operated upon to provide the ears 8 and the connecting portion 9 therein is disposed in the position shown in Fig. 13 and one section of the strip is positioned on the part 13 of the anvil 12 as shown in Fig. 10, upon lowering the plunger 19, the lower edge thereof comes into bearing contact upon the strip section and at the same time its lateral side face bears against the face of the upstanding iange 18 on the anvil so that in the continued downward movement of the die plate the anvil and the strip section move as a unit therewith until the anvil engages the 'upper surface of the support 15. In this operation, the camming action between the beveled surfaces 24c and 27 causes an inward movement of the plate 25 beneath the opposite edge portion of the sheet metal strip section to the position si'ibstantially indicatcd in Fig. 11. At this time, the knife 38 operates to cut out the narrow portion 9 of the sheet metal strip at the right hand end of the die plate 20 and thus separate the section which is positioned upon the anvil l2 and the plate 25 from the ren'iaining part of the strip. As the die plate 20 now continucs its downward movement and the plate 25 simultaneously moves inwardly beneath said strip section towards the anvil12, the lower edge of the die plate forces the intermediate part of the sheet metal strip section downwardly throughout the length of said section lwtwecn the flange 13 of the anvil and the opposed edge of the plate 25, thereby producing the longitudinally extending channel 3.) in the fran'ie-part. The shoulder 21 of the die plate 20 bears upon one edge portion of the frame part at one side of the channel 39 forcing the same upon the surface of the flange 13 while the edge of the table 25 constitutes a fulcrum against which the opposite edge portion of the frame part bears so that in the movement of said plate, it is forced upwardly against the obliquely lli) inclined surface 21 of the die plate. There is in this mannir prov ded the frame part 8 constituting integral extensions of the flange 41.

When the die plate 20 is raised, the plate 25 and the anvil 12 return to their normal:

positions, and in the upward movement of the anvil 12, the formed frame part is dislodged and drops downwardly between the support 15 and the table 11, as shown in Fig. 12of thcdrawings. The stock is then fed from'table 7 over table 11 and upon the anvil tioned as shown in Fig. 13. Pressure on the plate 36 is then released so that member 31 is forced downwardly by the s 'iring and the part 38 of said member enters between the opposed spaced ears 8, thus preventing any longitudinal shifting movement of the strip during the operation of the shaping die 20 and the cutting die 38 so that the accurate cutting out or removal of the connecting portion 9 between the sections of the sheet metal strip is assured, whereby a perfectly finished product will be obtained.

From the foregoing description, considered in connection with the accompanying drawings, it will be seen that I have devised a machine for very rapidly and accurately producing such sheet metal frame parts for ladies hand bags and the like. It is of course understood that in the use of these frame parts. the material constituting the body wall of the bag is connected with the flanges ll of the complementary frame sections while the other flanges 4O abut against each other when the bag is closed. It will further be understood that these frame parts may be bent or shaped as desired by other operations in accordance with the particular outline form of the bag.

it will be seen that by means of my present improvements, the edges of the ears provided at the ends of the frame parts are entirely smooth and unbrokenso that no subsequent additional operations are necessary in order to properlv finish these ends of the frame parts. The-form and arrangement of the several cooperating elements as above described also insures the positive and reliable operation of the mechanism whereby perfect uniformity in the resultant product is obtained.

I have herein shown an embodiment of the invention, which has given very satis factory results in practical operation. Nevertheless, it is to be understood that the essential features of my presentimprovements might also be incorporated in various other alternative mechanical structures, and I accordingly reserve the privilege of resortmg to all such legitimate changes therein as may be fairly incorporated within the spirit and sc pe o thei veiiti n @SChilIlIQd-Q Iclaim: y 1.
