Appiiation lea February 11, 1925. seriai No. 8,442.

The invention relates to dies. In the making of articles of various shapes from thin sheet metal, such as alu-Y minum foil or .from paper or other sheet material capable of being pressed or formed into the desired shape, it has been customary to shape the sheet material between specially made male and female dies with fixed 1mpressions so thatonly one article of a certain shape could be produced with ea'ch set of dies. Such laprocedure of forming thev articles involved a great expense indie Vcost since a distinct set of dies hadfto be'made for each particular form orarticle to be produced, and this situation has prevented the successful marketing of ornamental articles, such as Christmas-tree ornaments of stand- Y ard form, up to the present time. VOne Yof the objects of this invention is to vprovide a die'construction suitable for making-orner ments or other articles in which one o ftheV dies is so constructed and arranged asl to conform to a vgreat 'variety of shapes and sizes of forming dies, so rthat `the cost of V dies for forming' the articles is materially reduced and ornaments of Vstamped form, such as Christmas-tree ornaments, made of thin sheet metal can be produced at a cost` provide a die construction in whichone of theV dies is used to press the material being lformed against the forming die,V said firstnamed die being composed of a pluralityrof independently movable elements that are yieldingly mounted4 so that they `may :be

. moved to automatically adjustV themselves to conformto the shape of said forming die.

YA further object of .the invention is to provide a die construction whereby blanks of sheet material may be subjected to a 'cor-V rugat-ing process to form such blanks in articles of the desired shape. l

The invention further consistsl in the sev.-V

Fig. 5 is a detail sectional view similar to Fig. 3, Vshowing thel forming die in-an intermediate position; 1 I Fig. 6 isa detail sectional view taken von the line 6`6 of Fig..5; 'i i I Figs. 7 and` 8`are detail sectional views. of the sheeteholding parts of the'dies,Fig. 7 showing the parts separated and Fig. 8A showing the parts in operative position;

Figa `9, 10 and 11- are4 detail sectional views of forming' diesof different shapes for use with the adjustable die; Fig. 12 is an elevation'vievs7 of an orna. ment fashioned by the die-mechanism embodying the invention.- i The adjustable die member.V includes a. frame 14 having a plurality of radially ldisposedwslots 15 formed therein and cooperating With a top frame 'member 16, secured to said Vframe 14, to form a'plurality of radially disposed guid'eways which `are vpreferably inclined upwardly, as -shown in Fig. 8. 'i

In each of the guideways'formed vas above described, a presser bar orxmember 171is5'slidably mounted. Each of these bars ispro! vided with a beveled edge 1'8 lat, its forming end which is also rounded, as'at 19. Flach bar is limited in its inward movement by a Y stop-pin 2O adjustablyjmountedon an arm 21 secured to the bar and engageablewit-ha part of the frame, here shown as an annular surface 22. i

their stop `position i by means of' 'a strong Y engages the en'd 2/1 of each bar. L f

The forming die 25 may -be 'of'a-ny shape desired, either Asymmetrical or unsymmetrica'l7 and where a corrugated article is to, be formed isv provided with a fl-uted or corrugated surface 26, and soalined relativeto the adjustable die that-the beveled edges 18 of the presser bars line up ,with the bottoms of theA flutes or radially disposedjcorrugations 27 as shown in Fin.` 6. This lformin a e g die may be-moved relativel to the' adjustable die, in any suitable manner, and is generally movedY up and down by connection ofy an' operating rod 28` with a suitable press meohanism. A forming die of one shape islshovml.'

The bars are 1 independently `movable and are normallypressed inward to.

in Figq andfforming dies of other shapes i that may be tused in connection with the adjustable die are shown inrFigs. 9, and 11.V

4With the' above construction a piece of i sheet material, las inet-a1 foil,` paper or other material, is placed between the dies vand then j as the forming die descends and moves vpast the presser` bars 17 the material is formed by said bars into the'shape of Vthe *forming die, since the bars are forced outwardly by said die 25 as the materialrwith 'Y said Vdiemoves over said bars. -As Y the presser'bars Vreadily conform to various Y' a singlev adjustable die.

Ashapes which the forming die may have, a greatvaretv of articles may be made with In some instances I iind that it is desirable to exert `pressure upon the material be- Vilflgsshaped- Without permanently'clamping r'it during the forming operation, and for this purposeI provide a presser or clamping' Vmember 29 movable with and relative to the formingV die and'cooperating with a fixed 'member 30 `on-the top of theadjustable die.

For corrugated articles these members 29' and 30` are kprovided with radially: disposed Vcor'rugations 31 and 32 adapted-to register as shown in Fig.`8, the corrugation 32 being alinedf'with those formed on the forming die; The member 29 is connected with the die'25vby means of a cylindrical part 33 Vwhich Vforms 'a guide for. the .forming die 25' connected by screws ,-311 Y with cap rmember 375 slidably mounted on the-rod 28 and alined with the die 25A by means of a pair of spaced guide rods 36l secured to the basev ofthe forming die and projecting through. openings 37'in said cap VThe'member 2.9-may,
